- relevant mailing-list or to the newsgroup.
+If you have problems that seem to be due to kernel bugs, please follow the
+instructions at 'Documentation/admin-guide/reporting-issues.rst'.
- - In all bug-reports, *please* tell what kernel you are talking about,
- how to duplicate the problem, and what your setup is (use your common
- sense). If the problem is new, tell me so, and if the problem is
- old, please try to tell me when you first noticed it.
-
- - If the bug results in a message like::

-
- or similar kernel debugging information on your screen or in your
- system log, please duplicate it *exactly*. The dump may look
- incomprehensible to you, but it does contain information that may
- help debugging the problem. The text above the dump is also
- important: it tells something about why the kernel dumped code (in
- the above example, it's due to a bad kernel pointer). More information
- on making sense of the dump is in Documentation/admin-guide/bug-hunting.rst
-
- - If you compiled the kernel with CONFIG_KALLSYMS you can send the dump
- as is, otherwise you will have to use the ``ksymoops`` program to make
- sense of the dump (but compiling with CONFIG_KALLSYMS is usually preferred).
- This utility can be downloaded from
- https://www.kernel.org/pub/linux/utils/kernel/ksymoops/ .
- Alternatively, you can do the dump lookup by hand:
-
- - In debugging dumps like the above, it helps enormously if you can
- look up what the EIP value means. The hex value as such doesn't help
- me or anybody else very much: it will depend on your particular
- kernel setup. What you should do is take the hex value from the EIP
- line (ignore the ``0010:``), and look it up in the kernel namelist to
- see which kernel function contains the offending address.
-
- To find out the kernel function name, you'll need to find the system
- binary associated with the kernel that exhibited the symptom. This is
- the file 'linux/vmlinux'. To extract the namelist and match it against
- the EIP from the kernel crash, do::
-
- nm vmlinux | sort | less
-
- This will give you a list of kernel addresses sorted in ascending
- order, from which it is simple to find the function that contains the
- offending address. Note that the address given by the kernel
- debugging messages will not necessarily match exactly with the
- function addresses (in fact, that is very unlikely), so you can't
- just 'grep' the list: the list will, however, give you the starting
- point of each kernel function, so by looking for the function that
- has a starting address lower than the one you are searching for but
- is followed by a function with a higher address you will find the one
- you want. In fact, it may be a good idea to include a bit of
- "context" in your problem report, giving a few lines around the
- interesting one.
-
- If you for some reason cannot do the above (you have a pre-compiled
- kernel image or similar), telling me as much about your setup as
- possible will help. Please read
- 'Documentation/admin-guide/reporting-issues.rst' for details.
-
- - Alternatively, you can use gdb on a running kernel. (read-only; i.e. you
- cannot change values or set break points.) To do this, first compile the
- kernel with -g; edit arch/x86/Makefile appropriately, then do a ``make
- clean``. You'll also need to enable CONFIG_PROC_FS (via ``make config``).
-
- After you've rebooted with the new kernel, do ``gdb vmlinux /proc/kcore``.
- You can now use all the usual gdb commands. The command to look up the
- point where your system crashed is ``l *0xXXXXXXXX``. (Replace the XXXes
- with the EIP value.)
-
- gdb'ing a non-running kernel currently fails because ``gdb`` (wrongly)
- disregards the starting offset for which the kernel is compiled.
+Hints on understanding kernel bug reports are in
+'Documentation/admin-guide/bug-hunting.rst'. More on debugging the kernel
+with gdb is in 'Documentation/dev-tools/gdb-kernel-debugging.rst' and

+Clang implementation notes
+==========================
+
+This document provides more details specific to the Clang/LLVM implementation of the eBPF instruction set.
+
+Versions
+========
+
+Clang defined "CPU" versions, where a CPU version of 3 corresponds to the current eBPF ISA.
+
+Clang can select the eBPF ISA version using ``-mcpu=v3`` for example to select version 3.
+
+Arithmetic instructions
+=======================
+
+For CPU versions prior to 3, Clang v7.0 and later can enable ``BPF_ALU`` support with
+``-Xclang -target-feature -Xclang +alu32``. In CPU version 3, support is automatically included.
+
+Atomic operations
+=================
+
+Clang can generate atomic instructions by default when ``-mcpu=v3`` is
+enabled. If a lower version for ``-mcpu`` is set, the only atomic instruction
+Clang can generate is ``BPF_ADD`` *without* ``BPF_FETCH``. If you need to enable
+the atomics features, while keeping a lower ``-mcpu`` version, you can use
+``-Xclang -target-feature -Xclang +alu32``.

+ applications using low power constrained nodes and is compliant
+ with the IEEE 802.3cg-2019 Ethernet standard for long reach
+ 10 Mbps single pair Ethernet (SPE).
+
+ The device has a 4-wire SPI interface for communication
+ between the MAC and host processor.

- "rx_resp": MSGDMA Rx dispatcher response space region
- "s1": SGDMA descriptor memory
-- interrupts: Should contain the TSE interrupts and its mode.
-- interrupt-names: Should contain the interrupt names
- "rx_irq": xDMA Rx dispatcher interrupt
- "tx_irq": xDMA Tx dispatcher interrupt
-- rx-fifo-depth: MAC receive FIFO buffer depth in bytes
-- tx-fifo-depth: MAC transmit FIFO buffer depth in bytes
-- phy-mode: See ethernet.txt in the same directory.
-- phy-handle: See ethernet.txt in the same directory.
-- phy-addr: See ethernet.txt in the same directory. A configuration should
- include phy-handle or phy-addr.
-- altr,has-supplementary-unicast:
- If present, TSE supports additional unicast addresses.
- Otherwise additional unicast addresses are not supported.

- If present, TSE supports a hash based multicast filter.
- Otherwise, hash-based multicast filtering is not supported.
-
-- mdio device tree subnode: When the TSE has a phy connected to its local
- mdio, there must be device tree subnode with the following
- required properties:
-
- - compatible: Must be "altr,tse-mdio".
- - #address-cells: Must be <1>.
- - #size-cells: Must be <0>.
-
- For each phy on the mdio bus, there must be a node with the following
- fields:
-
- - reg: phy id used to communicate to phy.
- - device_type: Must be "ethernet-phy".
-
-The MAC address will be determined using the optional properties defined in

description: |
- Port 5 of mt7530 and mt7621 switch is muxed between:
- 1. GMAC5: GMAC5 can interface with another external MAC or PHY.
- 2. PHY of port 0 or port 4: PHY interfaces with an external MAC like 2nd GMAC
- of the SOC. Used in many setups where port 0/4 becomes the WAN port.
- Note: On a MT7621 SOC with integrated switch: 2nd GMAC can only connected to
- GMAC5 when the gpios for RGMII2 (GPIO 22-33) are not used and not
- connected to external component!
+ There are two versions of MT7530, standalone and in a multi-chip module.
- Port 5 modes/configurations:
- 1. Port 5 is disabled and isolated: An external phy can interface to the 2nd
- GMAC of the SOC.
- In the case of a build-in MT7530 switch, port 5 shares the RGMII bus with 2nd
- GMAC and an optional external phy. Mind the GPIO/pinctl settings of the SOC!
- 2. Port 5 is muxed to PHY of port 0/4: Port 0/4 interfaces with 2nd GMAC.
- It is a simple MAC to PHY interface, port 5 needs to be setup for xMII mode
- and RGMII delay.
- 3. Port 5 is muxed to GMAC5 and can interface to an external phy.
- Port 5 becomes an extra switch port.
- Only works on platform where external phy TX<->RX lines are swapped.
- Like in the Ubiquiti ER-X-SFP.
- 4. Port 5 is muxed to GMAC5 and interfaces with the 2nd GAMC as 2nd CPU port.
- Currently a 2nd CPU port is not supported by DSA code.
+ MT7530 is a part of the multi-chip module in MT7620AN, MT7620DA, MT7620DAN,
+ MT7620NN, MT7621AT, MT7621DAT, MT7621ST and MT7623AI SoCs.
- Depending on how the external PHY is wired:
- 1. normal: The PHY can only connect to 2nd GMAC but not to the switch
- 2. swapped: RGMII TX, RX are swapped; external phy interface with the switch as
- a ethernet port. But can't interface to the 2nd GMAC.
+ MT7530 in MT7620AN, MT7620DA, MT7620DAN and MT7620NN SoCs has got 10/100 PHYs
+ and the switch registers are directly mapped into SoC's memory map rather than
+ using MDIO. The DSA driver currently doesn't support this.
- Based on the DT the port 5 mode is configured.
+ There is only the standalone version of MT7531.
- Driver tries to lookup the phy-handle of the 2nd GMAC of the master device.
- When phy-handle matches PHY of port 0 or 4 then port 5 set-up as mode 2.
- phy-mode must be set, see also example 2 below!
- * mt7621: phy-mode = "rgmii-txid";
- * mt7623: phy-mode = "rgmii";
+ Port 5 on MT7530 has got various ways of configuration.
- CPU-Ports need a phy-mode property:
- Allowed values on mt7530 and mt7621:
- - "rgmii"
- - "trgmii"
- On mt7531:
- - "1000base-x"
- - "2500base-x"
- - "rgmii"
- - "sgmii"
+ For standalone MT7530:
+ - Port 5 can be used as a CPU port.
+
+ - PHY 0 or 4 of the switch can be muxed to connect to the gmac of the SoC
+ which port 5 is wired to. Usually used for connecting the wan port
+ directly to the CPU to achieve 2 Gbps routing in total.
+
+ The driver looks up the reg on the ethernet-phy node which the phy-handle
+ property refers to on the gmac node to mux the specified phy.
+
+ The driver requires the gmac of the SoC to have "mediatek,eth-mac" as the
+ compatible string and the reg must be 1. So, for now, only gmac1 of an
+ MediaTek SoC can benefit this. Banana Pi BPI-R2 suits this.
+ Check out example 5 for a similar configuration.
+
+ - Port 5 can be wired to an external phy. Port 5 becomes a DSA slave.
+ Check out example 7 for a similar configuration.
+
+ For multi-chip module MT7530:
+
+ - Port 5 can be used as a CPU port.
+
+ - PHY 0 or 4 of the switch can be muxed to connect to gmac1 of the SoC.
+ Usually used for connecting the wan port directly to the CPU to achieve 2
+ Gbps routing in total.
+
+ The driver looks up the reg on the ethernet-phy node which the phy-handle
+ property refers to on the gmac node to mux the specified phy.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
+ Check out example 5.
+
+ - In case of an external phy wired to gmac1 of the SoC, port 5 must not be
+ enabled.
+
+ In case of muxing PHY 0 or 4, the external phy must not be enabled.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
+ Check out example 6.
+
+ - Port 5 can be muxed to an external phy. Port 5 becomes a DSA slave.
+ The external phy must be wired TX to TX to gmac1 of the SoC for this to
+ work. Ubiquiti EdgeRouter X SFP is wired this way.
+
+ Muxing PHY 0 or 4 won't work when the external phy is connected TX to TX.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with gpio function.
+ Check out example 7.

+description: |
+ There are multiple switches which are either part of the Ocelot-1 family, or
+ derivatives of this architecture. These switches can be found embedded in
+ various SoCs and accessed using MMIO, or as discrete chips and accessed over
+ SPI or PCIe. The present DSA binding shall be used when the host controlling
+ them performs packet I/O primarily through an Ethernet port of the switch
+ (which is attached to an Ethernet port of the host), rather than through
+ Frame DMA or register-based I/O.
+
+ VSC9953 (Seville):
+
+ This is found in the NXP T1040, where it is a memory-mapped platform
+ device.
+
+ The following PHY interface types are supported:
+
+ - phy-mode = "internal": on ports 8 and 9
+ - phy-mode = "sgmii": on ports 0, 1, 2, 3, 4, 5, 6, 7
+ - phy-mode = "qsgmii": on ports 0, 1, 2, 3, 4, 5, 6, 7
+ - phy-mode = "1000base-x": on ports 0, 1, 2, 3, 4, 5, 6, 7
+
+ VSC9959 (Felix):
+
+ This is found in the NXP LS1028A. It is a PCI device, part of the larger
+ enetc root complex. As a result, the ethernet-switch node is a sub-node of
+ the PCIe root complex node and its "reg" property conforms to the parent
+ node bindings, describing it as PF 5 of device 0, bus 0.
+
+ If any external switch port is enabled, the enetc PF2 (enetc_port2) should
+ be enabled as well. This is because the internal MDIO bus (exposed through
+ EA BAR 0) used to access the MAC PCS registers truly belongs to the enetc
+ port 2 and not to Felix.
+
+ The following PHY interface types are supported:
+
+ - phy-mode = "internal": on ports 4 and 5
+ - phy-mode = "sgmii": on ports 0, 1, 2, 3
+ - phy-mode = "qsgmii": on ports 0, 1, 2, 3
+ - phy-mode = "usxgmii": on ports 0, 1, 2, 3

-Microchip Ocelot switch driver family
-=====================================
-
-Felix
------
-
-Currently the switches supported by the felix driver are:
-
-- VSC9959 (Felix)
-- VSC9953 (Seville)
-
-The VSC9959 switch is found in the NXP LS1028A. It is a PCI device, part of the
-larger ENETC root complex. As a result, the ethernet-switch node is a sub-node
-of the PCIe root complex node and its "reg" property conforms to the parent
-node bindings:
-
-* reg: Specifies PCIe Device Number and Function Number of the endpoint device,
- in this case for the Ethernet L2Switch it is PF5 (of device 0, bus 0).
-
-It does not require a "compatible" string.
-
-The interrupt line is used to signal availability of PTP TX timestamps and for
-TSN frame preemption.
-
-For the external switch ports, depending on board configuration, "phy-mode" and
-"phy-handle" are populated by board specific device tree instances. Ports 4 and
-5 are fixed as internal ports in the NXP LS1028A instantiation.
-
-The CPU port property ("ethernet") configures the feature called "NPI port" in
-the Ocelot hardware core. The CPU port in Ocelot is a set of queues, which are
-connected, in the Node Processor Interface (NPI) mode, to an Ethernet port.
-By default, in fsl-ls1028a.dtsi, the NPI port is assigned to the internal
-2.5Gbps port@4, but can be moved to the 1Gbps port@5, depending on the specific
-use case. Moving the NPI port to an external switch port is hardware possible,
-but there is no platform support for the Linux system on the LS1028A chip to
-operate as an entire slave DSA chip. NPI functionality (and therefore DSA
-tagging) is supported on a single port at a time.
-
-Any port can be disabled (and in fsl-ls1028a.dtsi, they are indeed all disabled
-by default, and should be enabled on a per-board basis). But if any external
-switch port is enabled at all, the ENETC PF2 (enetc_port2) should be enabled as
-well, regardless of whether it is configured as the DSA master or not. This is
-because the Felix PHYLINK implementation accesses the MAC PCS registers, which
-in hardware truly belong to the ENETC port #2 and not to Felix.
-
-Supported PHY interface types (appropriate SerDes protocol setting changes are
-needed in the RCW binary):
-
-* phy_mode = "internal": on ports 4 and 5
-* phy_mode = "sgmii": on ports 0, 1, 2, 3
-* phy_mode = "qsgmii": on ports 0, 1, 2, 3
-* phy_mode = "usxgmii": on ports 0, 1, 2, 3
-* phy_mode = "2500base-x": on ports 0, 1, 2, 3
-
-For the rest of the device tree binding definitions, which are standard DSA and
-PCI, refer to the following documents:
-
-Documentation/devicetree/bindings/net/dsa/dsa.txt
-Documentation/devicetree/bindings/pci/pci.txt
-
-Example:
-
-&soc {
- pcie@1f0000000 { /* Integrated Endpoint Root Complex */
- ethernet-switch@0,5 {
- reg = <0x000500 0 0 0 0>;
- /* IEP INT_B */
- interrupts = <GIC_SPI 95 IRQ_TYPE_LEVEL_HIGH>;
-
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
-
- /* External ports */
- port@0 {
- reg = <0>;
- label = "swp0";
- };
-
- port@1 {
- reg = <1>;
- label = "swp1";
- };
-
- port@2 {
- reg = <2>;
- label = "swp2";
- };
-
- port@3 {
- reg = <3>;
- label = "swp3";
- };
-
- /* Tagging CPU port */
- port@4 {
- reg = <4>;
- ethernet = <&enetc_port2>;
- phy-mode = "internal";
-
- fixed-link {
- speed = <2500>;
- full-duplex;
- };
- };
-
- /* Non-tagging CPU port */
- port@5 {
- reg = <5>;
- phy-mode = "internal";
- status = "disabled";
-
- fixed-link {
- speed = <1000>;
- full-duplex;
- };
- };
- };
- };
- };
-};
-
-The VSC9953 switch is found inside NXP T1040. It is a platform device with the
-following required properties:
-
-- compatible:
- Must be "mscc,vsc9953-switch".
-
-Supported PHY interface types (appropriate SerDes protocol setting changes are
-needed in the RCW binary):
-
-* phy_mode = "internal": on ports 8 and 9
-* phy_mode = "sgmii": on ports 0, 1, 2, 3, 4, 5, 6, 7
-* phy_mode = "qsgmii": on ports 0, 1, 2, 3, 4, 5, 6, 7

What should an OEM do if they want to support Linux and Windows
using the same BIOS image? Often they need to do something different
for Linux to deal with how Linux is different from Windows.
-Here the BIOS should ask exactly what it wants to know:
+In this case, the OEM should create custom ASL to be executed by the
+Linux kernel and changes to Linux kernel drivers to execute this custom
+ASL. The easiest way to accomplish this is to introduce a device specific
+method (_DSM) that is called from the Linux kernel.
+
+In the past the kernel used to support something like:
_OSI("Linux-OEM-my_interface_name")
where 'OEM' is needed if this is an OEM-specific hook,
and 'my_interface_name' describes the hook, which could be a
quirk, a bug, or a bug-fix.
-In addition, the OEM should send a patch to upstream Linux
-via the linux-acpi@vger.kernel.org mailing list. When that patch
-is checked into Linux, the OS will answer "YES" when the BIOS
-on the OEM's system uses _OSI to ask if the interface is supported
-by the OS. Linux distributors can back-port that patch for Linux
-pre-installs, and it will be included by all distributions that
-re-base to upstream. If the distribution can not update the kernel binary,
-they can also add an acpi_osi=Linux-OEM-my_interface_name
-cmdline parameter to the boot loader, as needed.
-
-If the string refers to a feature where the upstream kernel
-eventually grows support, a patch should be sent to remove
-the string when that support is added to the kernel.
+However this was discovered to be abused by other BIOS vendors to change
+completely unrelated code on completely unrelated systems. This prompted
+an evaluation of all of it's uses. This uncovered that they aren't needed
+for any of the original reasons. As such, the kernel will not respond to
+any custom Linux-* strings by default.
That was easy. Read on, to find out how to do it wrong.

As of v4.15 of the Linux kernel, an smp_mb() was added to READ_ONCE() for
DEC Alpha, which means that about the only people who need to pay attention

-Linux DECnet Networking Layer Information
-=========================================
-
-1. Other documentation....
-==========================
-
- - Project Home Pages
- - http://www.chygwyn.com/ - Kernel info
- - http://linux-decnet.sourceforge.net/ - Userland tools
- - http://www.sourceforge.net/projects/linux-decnet/ - Status page
-
-2. Configuring the kernel
-=========================
-
-Be sure to turn on the following options:
-
- - CONFIG_DECNET (obviously)
- - CONFIG_PROC_FS (to see what's going on)
- - CONFIG_SYSCTL (for easy configuration)
-
-if you want to try out router support (not properly debugged yet)
-you'll need the following options as well...
-
- - CONFIG_DECNET_ROUTER (to be able to add/delete routes)
- - CONFIG_NETFILTER (will be required for the DECnet routing daemon)
-
-Don't turn on SIOCGIFCONF support for DECnet unless you are really sure
-that you need it, in general you won't and it can cause ifconfig to
-malfunction.
-
-Run time configuration has changed slightly from the 2.4 system. If you
-want to configure an endnode, then the simplified procedure is as follows:
-
- - Set the MAC address on your ethernet card before starting _any_ other
- network protocols.
-
-As soon as your network card is brought into the UP state, DECnet should
-start working. If you need something more complicated or are unsure how
-to set the MAC address, see the next section. Also all configurations which
-worked with 2.4 will work under 2.5 with no change.
-
-3. Command line options
-=======================
-
-You can set a DECnet address on the kernel command line for compatibility
-with the 2.4 configuration procedure, but in general it's not needed any more.
-If you do st a DECnet address on the command line, it has only one purpose
-which is that its added to the addresses on the loopback device.
-
-With 2.4 kernels, DECnet would only recognise addresses as local if they
-were added to the loopback device. In 2.5, any local interface address
-can be used to loop back to the local machine. Of course this does not
-prevent you adding further addresses to the loopback device if you
-want to.
-
-N.B. Since the address list of an interface determines the addresses for
-which "hello" messages are sent, if you don't set an address on the loopback
-interface then you won't see any entries in /proc/net/neigh for the local
-host until such time as you start a connection. This doesn't affect the
-operation of the local communications in any other way though.
-
-The kernel command line takes options looking like the following::
-
- decnet.addr=1,2
-
-the two numbers are the node address 1,2 = 1.2 For 2.2.xx kernels
-and early 2.3.xx kernels, you must use a comma when specifying the
-DECnet address like this. For more recent 2.3.xx kernels, you may
-use almost any character except space, although a `.` would be the most
-obvious choice :-)
-
-There used to be a third number specifying the node type. This option
-has gone away in favour of a per interface node type. This is now set
-using /proc/sys/net/decnet/conf/<dev>/forwarding. This file can be
-set with a single digit, 0=EndNode, 1=L1 Router and 2=L2 Router.
-
-There are also equivalent options for modules. The node address can
-also be set through the /proc/sys/net/decnet/ files, as can other system
-parameters.
-
-Currently the only supported devices are ethernet and ip_gre. The
-ethernet address of your ethernet card has to be set according to the DECnet
-address of the node in order for it to be autoconfigured (and then appear in
-/proc/net/decnet_dev). There is a utility available at the above
-FTP sites called dn2ethaddr which can compute the correct ethernet
-address to use. The address can be set by ifconfig either before or
-at the time the device is brought up. If you are using RedHat you can
-add the line::
-
- MACADDR=AA:00:04:00:03:04
-
-or something similar, to /etc/sysconfig/network-scripts/ifcfg-eth0 or
-wherever your network card's configuration lives. Setting the MAC address
-of your ethernet card to an address starting with "hi-ord" will cause a
-DECnet address which matches to be added to the interface (which you can
-verify with iproute2).
-
-The default device for routing can be set through the /proc filesystem
-by setting /proc/sys/net/decnet/default_device to the
-device you want DECnet to route packets out of when no specific route
-is available. Usually this will be eth0, for example::
-
- echo -n "eth0" >/proc/sys/net/decnet/default_device
-
-If you don't set the default device, then it will default to the first
-ethernet card which has been autoconfigured as described above. You can
-confirm that by looking in the default_device file of course.
-
-There is a list of what the other files under /proc/sys/net/decnet/ do
-on the kernel patch web site (shown above).
-
-4. Run time kernel configuration
-================================
-
-
-This is either done through the sysctl/proc interface (see the kernel web
-pages for details on what the various options do) or through the iproute2
-package in the same way as IPv4/6 configuration is performed.
-
-Documentation for iproute2 is included with the package, although there is
-as yet no specific section on DECnet, most of the features apply to both
-IP and DECnet, albeit with DECnet addresses instead of IP addresses and
-a reduced functionality.
-
-If you want to configure a DECnet router you'll need the iproute2 package
-since its the _only_ way to add and delete routes currently. Eventually
-there will be a routing daemon to send and receive routing messages for
-each interface and update the kernel routing tables accordingly. The
-routing daemon will use netfilter to listen to routing packets, and
-rtnetlink to update the kernels routing tables.
-
-The DECnet raw socket layer has been removed since it was there purely
-for use by the routing daemon which will now use netfilter (a much cleaner
-and more generic solution) instead.
-
-5. How can I tell if its working?
-=================================
-
-Here is a quick guide of what to look for in order to know if your DECnet
-kernel subsystem is working.
-
- - Is the node address set (see /proc/sys/net/decnet/node_address)
- - Is the node of the correct type
- (see /proc/sys/net/decnet/conf/<dev>/forwarding)
- - Is the Ethernet MAC address of each Ethernet card set to match
- the DECnet address. If in doubt use the dn2ethaddr utility available
- at the ftp archive.
- - If the previous two steps are satisfied, and the Ethernet card is up,
- you should find that it is listed in /proc/net/decnet_dev and also
- that it appears as a directory in /proc/sys/net/decnet/conf/. The
- loopback device (lo) should also appear and is required to communicate
- within a node.
- - If you have any DECnet routers on your network, they should appear
- in /proc/net/decnet_neigh, otherwise this file will only contain the
- entry for the node itself (if it doesn't check to see if lo is up).
- - If you want to send to any node which is not listed in the
- /proc/net/decnet_neigh file, you'll need to set the default device
- to point to an Ethernet card with connection to a router. This is
- again done with the /proc/sys/net/decnet/default_device file.
- - Try starting a simple server and client, like the dnping/dnmirror
- over the loopback interface. With luck they should communicate.
- For this step and those after, you'll need the DECnet library
- which can be obtained from the above ftp sites as well as the
- actual utilities themselves.
- - If this seems to work, then try talking to a node on your local
- network, and see if you can obtain the same results.
- - At this point you are on your own... :-)
-
-6. How to send a bug report
-===========================
-
-If you've found a bug and want to report it, then there are several things
-you can do to help me work out exactly what it is that is wrong. Useful
-information (_most_ of which _is_ _essential_) includes:
-
- - What kernel version are you running ?
- - What version of the patch are you running ?
- - How far though the above set of tests can you get ?
- - What is in the /proc/decnet* files and /proc/sys/net/decnet/* files ?
- - Which services are you running ?
- - Which client caused the problem ?
- - How much data was being transferred ?
- - Was the network congested ?
- - How can the problem be reproduced ?
- - Can you use tcpdump to get a trace ? (N.B. Most (all?) versions of
- tcpdump don't understand how to dump DECnet properly, so including
- the hex listing of the packet contents is _essential_, usually the -x flag.
- You may also need to increase the length grabbed with the -s flag. The
- -e flag also provides very useful information (ethernet MAC addresses))
-
-7. MAC FAQ
-==========
-
-A quick FAQ on ethernet MAC addresses to explain how Linux and DECnet
-interact and how to get the best performance from your hardware.
-
-Ethernet cards are designed to normally only pass received network frames
-to a host computer when they are addressed to it, or to the broadcast address.
-
-Linux has an interface which allows the setting of extra addresses for
-an ethernet card to listen to. If the ethernet card supports it, the
-filtering operation will be done in hardware, if not the extra unwanted packets
-received will be discarded by the host computer. In the latter case,
-significant processor time and bus bandwidth can be used up on a busy
-network (see the NAPI documentation for a longer explanation of these
-effects).
-
-DECnet makes use of this interface to allow running DECnet on an ethernet
-card which has already been configured using TCP/IP (presumably using the
-built in MAC address of the card, as usual) and/or to allow multiple DECnet
-addresses on each physical interface. If you do this, be aware that if your
-ethernet card doesn't support perfect hashing in its MAC address filter
-then your computer will be doing more work than required. Some cards
-will simply set themselves into promiscuous mode in order to receive
-packets from the DECnet specified addresses. So if you have one of these
-cards its better to set the MAC address of the card as described above
-to gain the best efficiency. Better still is to use a card which supports
-NAPI as well.
-
-
-8. Mailing list
-===============
-
-If you are keen to get involved in development, or want to ask questions
-about configuration, or even just report bugs, then there is a mailing
-list that you can join, details are at:

+==========
+
+The ``ice`` driver supports port splitting only for port 0, as the FW has

+
+A system reboot is required for port split to be applied.
+
+The following command will select the port split option with 4 ports:

+.. code:: shell
+
+ $ devlink port split pci/0000:16:00.0/0 count 4
+
+The list of all available port options will be printed to dynamic debug after

+
+Affinity of user ports to CPU ports
+-----------------------------------
+
+Typically, DSA switches are attached to the host via a single Ethernet
+interface, but in cases where the switch chip is discrete, the hardware design
+may permit the use of 2 or more ports connected to the host, for an increase in
+termination throughput.
+
+DSA can make use of multiple CPU ports in two ways. First, it is possible to
+statically assign the termination traffic associated with a certain user port
+to be processed by a certain CPU port. This way, user space can implement
+custom policies of static load balancing between user ports, by spreading the
+affinities according to the available CPU ports.
+
+Secondly, it is possible to perform load balancing between CPU ports on a per
+packet basis, rather than statically assigning user ports to CPU ports.
+This can be achieved by placing the DSA masters under a LAG interface (bonding
+or team). DSA monitors this operation and creates a mirror of this software LAG
+on the CPU ports facing the physical DSA masters that constitute the LAG slave
+devices.
+
+To make use of multiple CPU ports, the firmware (device tree) description of
+the switch must mark all the links between CPU ports and their DSA masters
+using the ``ethernet`` reference/phandle. At startup, only a single CPU port
+and DSA master will be used - the numerically first port from the firmware
+description which has an ``ethernet`` property. It is up to the user to
+configure the system for the switch to use other masters.
+
+DSA uses the ``rtnl_link_ops`` mechanism (with a "dsa" ``kind``) to allow
+changing the DSA master of a user port. The ``IFLA_DSA_MASTER`` u32 netlink
+attribute contains the ifindex of the master device that handles each slave
+device. The DSA master must be a valid candidate based on firmware node
+information, or a LAG interface which contains only slaves which are valid
+candidates.
+
+Using iproute2, the following manipulations are possible:
+
+ .. code-block:: sh
+
+ # See the DSA master in current use
+ ip -d link show dev swp0
+ (...)
+ dsa master eth0
+
+ # Static CPU port distribution
+ ip link set swp0 type dsa master eth1
+ ip link set swp1 type dsa master eth0
+ ip link set swp2 type dsa master eth1
+ ip link set swp3 type dsa master eth0
+
+ # CPU ports in LAG, using explicit assignment of the DSA master
+ ip link add bond0 type bond mode balance-xor && ip link set bond0 up
+ ip link set eth1 down && ip link set eth1 master bond0
+ ip link set swp0 type dsa master bond0
+ ip link set swp1 type dsa master bond0
+ ip link set swp2 type dsa master bond0
+ ip link set swp3 type dsa master bond0
+ ip link set eth0 down && ip link set eth0 master bond0
+ ip -d link show dev swp0
+ (...)
+ dsa master bond0
+
+ # CPU ports in LAG, relying on implicit migration of the DSA master
+ ip link add bond0 type bond mode balance-xor && ip link set bond0 up
+ ip link set eth0 down && ip link set eth0 master bond0
+ ip link set eth1 down && ip link set eth1 master bond0
+ ip -d link show dev swp0
+ (...)
+ dsa master bond0
+
+Notice that in the case of CPU ports under a LAG, the use of the
+``IFLA_DSA_MASTER`` netlink attribute is not strictly needed, but rather, DSA
+reacts to the ``IFLA_MASTER`` attribute change of its present master (``eth0``)
+and migrates all user ports to the new upper of ``eth0``, ``bond0``. Similarly,
+when ``bond0`` is destroyed using ``RTM_DELLINK``, DSA migrates the user ports
+that were assigned to this interface to the first physical DSA master which is
+eligible, based on the firmware description (it effectively reverts to the
+startup configuration).
+
+In a setup with more than 2 physical CPU ports, it is therefore possible to mix
+static user to CPU port assignment with LAG between DSA masters. It is not
+possible to statically assign a user port towards a DSA master that has any
+upper interfaces (this includes LAG devices - the master must always be the LAG
+in this case).
+
+Live changing of the DSA master (and thus CPU port) affinity of a user port is
+permitted, in order to allow dynamic redistribution in response to traffic.
+
+Physical DSA masters are allowed to join and leave at any time a LAG interface
+used as a DSA master; however, DSA will reject a LAG interface as a valid
+candidate for being a DSA master unless it has at least one physical DSA master
+as a slave device.

Ethernet switch will be able to process these incoming frames from the

+device is thus also a DSA master, but the LAG slave devices continue to be DSA
+masters as well (just with no user port assigned to them; this is needed for

+Network Function Representors
+=============================
+
+This document describes the semantics and usage of representor netdevices, as
+used to control internal switching on SmartNICs. For the closely-related port
+representors on physical (multi-port) switches, see
+:ref:`Documentation/networking/switchdev.rst <switchdev>`.
+
+Motivation
+----------
+
+Since the mid-2010s, network cards have started offering more complex
+virtualisation capabilities than the legacy SR-IOV approach (with its simple
+MAC/VLAN-based switching model) can support. This led to a desire to offload
+software-defined networks (such as OpenVSwitch) to these NICs to specify the
+network connectivity of each function. The resulting designs are variously
+called SmartNICs or DPUs.
+
+Network function representors bring the standard Linux networking stack to
+virtual switches and IOV devices. Just as each physical port of a Linux-
+controlled switch has a separate netdev, so does each virtual port of a virtual
+switch.
+When the system boots, and before any offload is configured, all packets from
+the virtual functions appear in the networking stack of the PF via the
+representors. The PF can thus always communicate freely with the virtual
+functions.
+The PF can configure standard Linux forwarding between representors, the uplink
+or any other netdev (routing, bridging, TC classifiers).
+
+Thus, a representor is both a control plane object (representing the function in
+administrative commands) and a data plane object (one end of a virtual pipe).
+As a virtual link endpoint, the representor can be configured like any other
+netdevice; in some cases (e.g. link state) the representee will follow the
+representor's configuration, while in others there are separate APIs to
+configure the representee.
+
+Definitions
+-----------
+
+This document uses the term "switchdev function" to refer to the PCIe function
+which has administrative control over the virtual switch on the device.
+Typically, this will be a PF, but conceivably a NIC could be configured to grant
+these administrative privileges instead to a VF or SF (subfunction).
+Depending on NIC design, a multi-port NIC might have a single switchdev function
+for the whole device or might have a separate virtual switch, and hence
+switchdev function, for each physical network port.
+If the NIC supports nested switching, there might be separate switchdev
+functions for each nested switch, in which case each switchdev function should
+only create representors for the ports on the (sub-)switch it directly
+administers.
+
+A "representee" is the object that a representor represents. So for example in
+the case of a VF representor, the representee is the corresponding VF.
+
+What does a representor do?
+---------------------------
+
+A representor has three main roles.
+
+1. It is used to configure the network connection the representee sees, e.g.
+ link up/down, MTU, etc. For instance, bringing the representor
+ administratively UP should cause the representee to see a link up / carrier
+ on event.
+2. It provides the slow path for traffic which does not hit any offloaded
+ fast-path rules in the virtual switch. Packets transmitted on the
+ representor netdevice should be delivered to the representee; packets
+ transmitted by the representee which fail to match any switching rule should
+ be received on the representor netdevice. (That is, there is a virtual pipe
+ connecting the representor to the representee, similar in concept to a veth
+ pair.)
+ This allows software switch implementations (such as OpenVSwitch or a Linux
+ bridge) to forward packets between representees and the rest of the network.
+3. It acts as a handle by which switching rules (such as TC filters) can refer
+ to the representee, allowing these rules to be offloaded.
+
+The combination of 2) and 3) means that the behaviour (apart from performance)
+should be the same whether a TC filter is offloaded or not. E.g. a TC rule
+on a VF representor applies in software to packets received on that representor
+netdevice, while in hardware offload it would apply to packets transmitted by
+the representee VF. Conversely, a mirred egress redirect to a VF representor
+corresponds in hardware to delivery directly to the representee VF.
+
+What functions should have a representor?
+-----------------------------------------
+
+Essentially, for each virtual port on the device's internal switch, there
+should be a representor.
+Some vendors have chosen to omit representors for the uplink and the physical
+network port, which can simplify usage (the uplink netdev becomes in effect the
+physical port's representor) but does not generalise to devices with multiple
+ports or uplinks.
+
+Thus, the following should all have representors:
+
+ - VFs belonging to the switchdev function.
+ - Other PFs on the local PCIe controller, and any VFs belonging to them.
+ - PFs and VFs on external PCIe controllers on the device (e.g. for any embedded
+ System-on-Chip within the SmartNIC).
+ - PFs and VFs with other personalities, including network block devices (such
+ as a vDPA virtio-blk PF backed by remote/distributed storage), if (and only
+ if) their network access is implemented through a virtual switch port. [#]_
+ Note that such functions can require a representor despite the representee
+ not having a netdev.
+ - Subfunctions (SFs) belonging to any of the above PFs or VFs, if they have
+ their own port on the switch (as opposed to using their parent PF's port).
+ - Any accelerators or plugins on the device whose interface to the network is
+ through a virtual switch port, even if they do not have a corresponding PCIe
+ PF or VF.
+
+This allows the entire switching behaviour of the NIC to be controlled through
+representor TC rules.
+
+It is a common misunderstanding to conflate virtual ports with PCIe virtual
+functions or their netdevs. While in simple cases there will be a 1:1
+correspondence between VF netdevices and VF representors, more advanced device
+configurations may not follow this.
+A PCIe function which does not have network access through the internal switch
+(not even indirectly through the hardware implementation of whatever services
+the function provides) should *not* have a representor (even if it has a
+netdev).
+Such a function has no switch virtual port for the representor to configure or
+to be the other end of the virtual pipe.
+The representor represents the virtual port, not the PCIe function nor the 'end
+user' netdevice.
+
+.. [#] The concept here is that a hardware IP stack in the device performs the
+ translation between block DMA requests and network packets, so that only
+ network packets pass through the virtual port onto the switch. The network
+ access that the IP stack "sees" would then be configurable through tc rules;
+ e.g. its traffic might all be wrapped in a specific VLAN or VxLAN. However,
+ any needed configuration of the block device *qua* block device, not being a
+ networking entity, would not be appropriate for the representor and would
+ thus use some other channel such as devlink.
+ Contrast this with the case of a virtio-blk implementation which forwards the
+ DMA requests unchanged to another PF whose driver then initiates and
+ terminates IP traffic in software; in that case the DMA traffic would *not*
+ run over the virtual switch and the virtio-blk PF should thus *not* have a
+ representor.
+
+How are representors created?
+-----------------------------
+
+The driver instance attached to the switchdev function should, for each virtual
+port on the switch, create a pure-software netdevice which has some form of
+in-kernel reference to the switchdev function's own netdevice or driver private
+data (``netdev_priv()``).
+This may be by enumerating ports at probe time, reacting dynamically to the
+creation and destruction of ports at run time, or a combination of the two.
+
+The operations of the representor netdevice will generally involve acting
+through the switchdev function. For example, ``ndo_start_xmit()`` might send
+the packet through a hardware TX queue attached to the switchdev function, with
+either packet metadata or queue configuration marking it for delivery to the
+representee.
+
+How are representors identified?
+--------------------------------
+
+The representor netdevice should *not* directly refer to a PCIe device (e.g.
+through ``net_dev->dev.parent`` / ``SET_NETDEV_DEV()``), either of the
+representee or of the switchdev function.
+Instead, it should implement the ``ndo_get_devlink_port()`` netdevice op, which
+the kernel uses to provide the ``phys_switch_id`` and ``phys_port_name`` sysfs
+nodes. (Some legacy drivers implement ``ndo_get_port_parent_id()`` and
+``ndo_get_phys_port_name()`` directly, but this is deprecated.) See
+:ref:`Documentation/networking/devlink/devlink-port.rst <devlink_port>` for the
+details of this API.
+
+It is expected that userland will use this information (e.g. through udev rules)
+to construct an appropriately informative name or alias for the netdevice. For
+instance if the switchdev function is ``eth4`` then a representor with a
+``phys_port_name`` of ``p0pf1vf2`` might be renamed ``eth4pf1vf2rep``.
+
+There are as yet no established conventions for naming representors which do not
+correspond to PCIe functions (e.g. accelerators and plugins).
+
+How do representors interact with TC rules?
+-------------------------------------------
+
+Any TC rule on a representor applies (in software TC) to packets received by
+that representor netdevice. Thus, if the delivery part of the rule corresponds
+to another port on the virtual switch, the driver may choose to offload it to
+hardware, applying it to packets transmitted by the representee.
+
+Similarly, since a TC mirred egress action targeting the representor would (in
+software) send the packet through the representor (and thus indirectly deliver
+it to the representee), hardware offload should interpret this as delivery to
+the representee.
+
+As a simple example, if ``PORT_DEV`` is the physical port representor and
+``REP_DEV`` is a VF representor, the following rules::
+
+ tc filter add dev $REP_DEV parent ffff: protocol ipv4 flower \
+ action mirred egress redirect dev $PORT_DEV
+ tc filter add dev $PORT_DEV parent ffff: protocol ipv4 flower skip_sw \
+ action mirred egress mirror dev $REP_DEV
+
+would mean that all IPv4 packets from the VF are sent out the physical port, and
+all IPv4 packets received on the physical port are delivered to the VF in
+addition to ``PORT_DEV``. (Note that without ``skip_sw`` on the second rule,
+the VF would get two copies, as the packet reception on ``PORT_DEV`` would
+trigger the TC rule again and mirror the packet to ``REP_DEV``.)
+
+On devices without separate port and uplink representors, ``PORT_DEV`` would
+instead be the switchdev function's own uplink netdevice.
+
+Of course the rules can (if supported by the NIC) include packet-modifying
+actions (e.g. VLAN push/pop), which should be performed by the virtual switch.
+
+Tunnel encapsulation and decapsulation are rather more complicated, as they
+involve a third netdevice (a tunnel netdev operating in metadata mode, such as
+a VxLAN device created with ``ip link add vxlan0 type vxlan external``) and
+require an IP address to be bound to the underlay device (e.g. switchdev
+function uplink netdev or port representor). TC rules such as::
+
+ tc filter add dev $REP_DEV parent ffff: flower \
+ action tunnel_key set id $VNI src_ip $LOCAL_IP dst_ip $REMOTE_IP \
+ dst_port 4789 \
+ action mirred egress redirect dev vxlan0
+ tc filter add dev vxlan0 parent ffff: flower enc_src_ip $REMOTE_IP \
+ enc_dst_ip $LOCAL_IP enc_key_id $VNI enc_dst_port 4789 \
+ action tunnel_key unset action mirred egress redirect dev $REP_DEV
+
+where ``LOCAL_IP`` is an IP address bound to ``PORT_DEV``, and ``REMOTE_IP`` is
+another IP address on the same subnet, mean that packets sent by the VF should
+be VxLAN encapsulated and sent out the physical port (the driver has to deduce
+this by a route lookup of ``LOCAL_IP`` leading to ``PORT_DEV``, and also
+perform an ARP/neighbour table lookup to find the MAC addresses to use in the
+outer Ethernet frame), while UDP packets received on the physical port with UDP
+port 4789 should be parsed as VxLAN and, if their VSID matches ``$VNI``,
+decapsulated and forwarded to the VF.
+
+If this all seems complicated, just remember the 'golden rule' of TC offload:
+the hardware should ensure the same final results as if the packets were
+processed through the slow path, traversed software TC (except ignoring any
+``skip_hw`` rules and applying any ``skip_sw`` rules) and were transmitted or
+received through the representor netdevices.
+
+Configuring the representee's MAC
+---------------------------------
+
+The representee's link state is controlled through the representor. Setting the
+representor administratively UP or DOWN should cause carrier ON or OFF at the
+representee.
+
+Setting an MTU on the representor should cause that same MTU to be reported to
+the representee.
+(On hardware that allows configuring separate and distinct MTU and MRU values,
+the representor MTU should correspond to the representee's MRU and vice-versa.)
+
+Currently there is no way to use the representor to set the station permanent
+MAC address of the representee; other methods available to do this include:
+
+ - legacy SR-IOV (``ip link set DEVICE vf NUM mac LLADDR``)
+ - devlink port function (see **devlink-port(8)** and
+ :ref:`Documentation/networking/devlink/devlink-port.rst <devlink_port>`)

+22) Do not crash the kernel
+---------------------------
+
+In general, the decision to crash the kernel belongs to the user, rather
+than to the kernel developer.
+
+Avoid panic()
+*************
+
+panic() should be used with care and primarily only during system boot.
+panic() is, for example, acceptable when running out of memory during boot and
+not being able to continue.
+
+Use WARN() rather than BUG()
+****************************
+
+Do not add new code that uses any of the BUG() variants, such as BUG(),
+BUG_ON(), or VM_BUG_ON(). Instead, use a WARN*() variant, preferably
+WARN_ON_ONCE(), and possibly with recovery code. Recovery code is not
+required if there is no reasonable way to at least partially recover.
+
+"I'm too lazy to do error handling" is not an excuse for using BUG(). Major
+internal corruptions with no way of continuing may still use BUG(), but need
+good justification.
+
+Use WARN_ON_ONCE() rather than WARN() or WARN_ON()
+**************************************************
+
+WARN_ON_ONCE() is generally preferred over WARN() or WARN_ON(), because it
+is common for a given warning condition, if it occurs at all, to occur
+multiple times. This can fill up and wrap the kernel log, and can even slow
+the system enough that the excessive logging turns into its own, additional
+problem.
+
+Do not WARN lightly
+*******************
+
+WARN*() is intended for unexpected, this-should-never-happen situations.
+WARN*() macros are not to be used for anything that is expected to happen
+during normal operation. These are not pre- or post-condition asserts, for
+example. Again: WARN*() must not be used for a condition that is expected
+to trigger easily, for example, by user space actions. pr_warn_once() is a
+possible alternative, if you need to notify the user of a problem.
+
+Do not worry about panic_on_warn users
+**************************************
+
+A few more words about panic_on_warn: Remember that ``panic_on_warn`` is an
+available kernel option, and that many users set this option. This is why
+there is a "Do not WARN lightly" writeup, above. However, the existence of
+panic_on_warn users is not a valid reason to avoid the judicious use
+WARN*(). That is because, whoever enables panic_on_warn has explicitly
+asked the kernel to crash if a WARN*() fires, and such users must be
+prepared to deal with the consequences of a system that is somewhat more
+likely to crash.
+
+Use BUILD_BUG_ON() for compile-time assertions
+**********************************************
+
+The use of BUILD_BUG_ON() is acceptable and encouraged, because it is a
+compile-time assertion that has no effect at runtime.
+

-Master key vs. Subkeys
-----------------------
+Understanding PGP Subkeys
+-------------------------
-Subkeys are fully independent PGP keypairs that are tied to the "master"
-key using certifying key signatures (certificates). It is important to
-understand the following:
+A PGP key rarely consists of a single keypair -- usually it is a
+collection of independent subkeys that can be used for different
+purposes based on their capabilities, assigned at their creation time.
+PGP defines four capabilities that a key can have:
-1. There are no technical differences between the "master key" and "subkeys."
-2. At creation time, we assign functional limitations to each key by
- giving it specific capabilities.
-3. A PGP key can have 4 capabilities:
+- **[S]** keys can be used for signing
+- **[E]** keys can be used for encryption
+- **[A]** keys can be used for authentication
+- **[C]** keys can be used for certifying other keys
- - **[S]** key can be used for signing
- - **[E]** key can be used for encryption
- - **[A]** key can be used for authentication
- - **[C]** key can be used for certifying other keys
+The key with the **[C]** capability is often called the "master" key,
+but this terminology is misleading because it implies that the Certify
+key can be used in place of any of other subkey on the same chain (like
+a physical "master key" can be used to open the locks made for other
+keys). Since this is not the case, this guide will refer to it as "the
+Certify key" to avoid any ambiguity.
-4. A single key may have multiple capabilities.
-5. A subkey is fully independent from the master key. A message
- encrypted to a subkey cannot be decrypted with the master key. If you
- lose your private subkey, it cannot be recreated from the master key
- in any way.
+It is critical to fully understand the following:
-The key carrying the **[C]** (certify) capability is considered the
-"master" key because it is the only key that can be used to indicate
-relationship with other keys. Only the **[C]** key can be used to:
+1. All subkeys are fully independent from each other. If you lose a
+ private subkey, it cannot be restored or recreated from any other
+ private key on your chain.
+2. With the exception of the Certify key, there can be multiple subkeys
+ with identical capabilities (e.g. you can have 2 valid encryption
+ subkeys, 3 valid signing subkeys, but only one valid certification
+ subkey). All subkeys are fully independent -- a message encrypted to
+ one **[E]** subkey cannot be decrypted with any other **[E]** subkey
+ you may also have.
+3. A single subkey may have multiple capabilities (e.g. your **[C]** key
+ can also be your **[S]** key).
+
+The key carrying the **[C]** (certify) capability is the only key that
+can be used to indicate relationship with other keys. Only the **[C]**
+key can be used to:

+
+Coding Guidelines
+=================
+
+This document describes how to write Rust code in the kernel.
+
+
+Style & formatting
+------------------
+
+The code should be formatted using ``rustfmt``. In this way, a person
+contributing from time to time to the kernel does not need to learn and
+remember one more style guide. More importantly, reviewers and maintainers
+do not need to spend time pointing out style issues anymore, and thus
+less patch roundtrips may be needed to land a change.
+
+.. note:: Conventions on comments and documentation are not checked by
+ ``rustfmt``. Thus those are still needed to be taken care of.
+
+The default settings of ``rustfmt`` are used. This means the idiomatic Rust
+style is followed. For instance, 4 spaces are used for indentation rather
+than tabs.
+
+It is convenient to instruct editors/IDEs to format while typing,
+when saving or at commit time. However, if for some reason reformatting
+the entire kernel Rust sources is needed at some point, the following can be
+run::
+
+ make LLVM=1 rustfmt
+
+It is also possible to check if everything is formatted (printing a diff
+otherwise), for instance for a CI, with::
+
+ make LLVM=1 rustfmtcheck
+
+Like ``clang-format`` for the rest of the kernel, ``rustfmt`` works on
+individual files, and does not require a kernel configuration. Sometimes it may
+even work with broken code.
+
+
+Comments
+--------
+
+"Normal" comments (i.e. ``//``, rather than code documentation which starts
+with ``///`` or ``//!``) are written in Markdown the same way as documentation
+comments are, even though they will not be rendered. This improves consistency,
+simplifies the rules and allows to move content between the two kinds of
+comments more easily. For instance:
+
+.. code-block:: rust
+
+ // `object` is ready to be handled now.
+ f(object);
+
+Furthermore, just like documentation, comments are capitalized at the beginning
+of a sentence and ended with a period (even if it is a single sentence). This
+includes ``// SAFETY:``, ``// TODO:`` and other "tagged" comments, e.g.:
+
+.. code-block:: rust
+
+ // FIXME: The error should be handled properly.
+
+Comments should not be used for documentation purposes: comments are intended
+for implementation details, not users. This distinction is useful even if the
+reader of the source file is both an implementor and a user of an API. In fact,
+sometimes it is useful to use both comments and documentation at the same time.
+For instance, for a ``TODO`` list or to comment on the documentation itself.
+For the latter case, comments can be inserted in the middle; that is, closer to
+the line of documentation to be commented. For any other case, comments are
+written after the documentation, e.g.:
+
+.. code-block:: rust
+
+ /// Returns a new [`Foo`].
+ ///
+ /// # Examples
+ ///
+ // TODO: Find a better example.
+ /// ```
+ /// let foo = f(42);
+ /// ```
+ // FIXME: Use fallible approach.
+ pub fn f(x: i32) -> Foo {
+ // ...
+ }
+
+One special kind of comments are the ``// SAFETY:`` comments. These must appear
+before every ``unsafe`` block, and they explain why the code inside the block is
+correct/sound, i.e. why it cannot trigger undefined behavior in any case, e.g.:
+
+.. code-block:: rust
+
+ // SAFETY: `p` is valid by the safety requirements.
+ unsafe { *p = 0; }
+
+``// SAFETY:`` comments are not to be confused with the ``# Safety`` sections
+in code documentation. ``# Safety`` sections specify the contract that callers
+(for functions) or implementors (for traits) need to abide by. ``// SAFETY:``
+comments show why a call (for functions) or implementation (for traits) actually
+respects the preconditions stated in a ``# Safety`` section or the language
+reference.
+
+
+Code documentation
+------------------
+
+Rust kernel code is not documented like C kernel code (i.e. via kernel-doc).
+Instead, the usual system for documenting Rust code is used: the ``rustdoc``
+tool, which uses Markdown (a lightweight markup language).
+
+To learn Markdown, there are many guides available out there. For instance,
+the one at:
+
+ https://commonmark.org/help/
+
+This is how a well-documented Rust function may look like:
+
+.. code-block:: rust
+
+ /// Returns the contained [`Some`] value, consuming the `self` value,
+ /// without checking that the value is not [`None`].
+ ///
+ /// # Safety
+ ///
+ /// Calling this method on [`None`] is *[undefined behavior]*.
+ ///
+ /// [undefined behavior]: https://doc.rust-lang.org/reference/behavior-considered-undefined.html
+ ///
+ /// # Examples
+ ///
+ /// ```
+ /// let x = Some("air");
+ /// assert_eq!(unsafe { x.unwrap_unchecked() }, "air");
+ /// ```
+ pub unsafe fn unwrap_unchecked(self) -> T {
+ match self {
+ Some(val) => val,
+
+ // SAFETY: The safety contract must be upheld by the caller.
+ None => unsafe { hint::unreachable_unchecked() },
+ }
+ }
+
+This example showcases a few ``rustdoc`` features and some conventions followed
+in the kernel:
+
+ - The first paragraph must be a single sentence briefly describing what
+ the documented item does. Further explanations must go in extra paragraphs.
+
+ - Unsafe functions must document their safety preconditions under
+ a ``# Safety`` section.
+
+ - While not shown here, if a function may panic, the conditions under which
+ that happens must be described under a ``# Panics`` section.
+
+ Please note that panicking should be very rare and used only with a good
+ reason. In almost all cases, a fallible approach should be used, typically
+ returning a ``Result``.
+
+ - If providing examples of usage would help readers, they must be written in
+ a section called ``# Examples``.
+
+ - Rust items (functions, types, constants...) must be linked appropriately
+ (``rustdoc`` will create a link automatically).
+
+ - Any ``unsafe`` block must be preceded by a ``// SAFETY:`` comment
+ describing why the code inside is sound.
+
+ While sometimes the reason might look trivial and therefore unneeded,
+ writing these comments is not just a good way of documenting what has been
+ taken into account, but most importantly, it provides a way to know that
+ there are no *extra* implicit constraints.
+
+To learn more about how to write documentation for Rust and extra features,
+please take a look at the ``rustdoc`` book at:
+
+ https://doc.rust-lang.org/rustdoc/how-to-write-documentation.html
+
+
+Naming
+------
+
+Rust kernel code follows the usual Rust naming conventions:
+
+ https://rust-lang.github.io/api-guidelines/naming.html
+
+When existing C concepts (e.g. macros, functions, objects...) are wrapped into
+a Rust abstraction, a name as close as reasonably possible to the C side should
+be used in order to avoid confusion and to improve readability when switching
+back and forth between the C and Rust sides. For instance, macros such as
+``pr_info`` from C are named the same in the Rust side.
+
+Having said that, casing should be adjusted to follow the Rust naming
+conventions, and namespacing introduced by modules and types should not be
+repeated in the item names. For instance, when wrapping constants like:
+
+.. code-block:: c
+
+ #define GPIO_LINE_DIRECTION_IN 0
+ #define GPIO_LINE_DIRECTION_OUT 1
+
+The equivalent in Rust may look like (ignoring documentation):
+
+.. code-block:: rust
+
+ pub mod gpio {
+ pub enum LineDirection {
+ In = bindings::GPIO_LINE_DIRECTION_IN as _,
+ Out = bindings::GPIO_LINE_DIRECTION_OUT as _,
+ }
+ }
+
+That is, the equivalent of ``GPIO_LINE_DIRECTION_IN`` would be referred to as
+``gpio::LineDirection::In``. In particular, it should not be named
+``gpio::gpio_line_direction::GPIO_LINE_DIRECTION_IN``.

+General Information
+===================
+
+This document contains useful information to know when working with
+the Rust support in the kernel.
+
+
+Code documentation
+------------------
+
+Rust kernel code is documented using ``rustdoc``, its built-in documentation
+generator.
+
+The generated HTML docs include integrated search, linked items (e.g. types,
+functions, constants), source code, etc. They may be read at (TODO: link when
+in mainline and generated alongside the rest of the documentation):
+
+ http://kernel.org/
+
+The docs can also be easily generated and read locally. This is quite fast
+(same order as compiling the code itself) and no special tools or environment
+are needed. This has the added advantage that they will be tailored to
+the particular kernel configuration used. To generate them, use the ``rustdoc``
+target with the same invocation used for compilation, e.g.::
+
+ make LLVM=1 rustdoc
+
+To read the docs locally in your web browser, run e.g.::
+
+ xdg-open rust/doc/kernel/index.html
+
+To learn about how to write the documentation, please see coding-guidelines.rst.
+
+
+Extra lints
+-----------
+
+While ``rustc`` is a very helpful compiler, some extra lints and analyses are
+available via ``clippy``, a Rust linter. To enable it, pass ``CLIPPY=1`` to
+the same invocation used for compilation, e.g.::
+
+ make LLVM=1 CLIPPY=1
+
+Please note that Clippy may change code generation, thus it should not be
+enabled while building a production kernel.
+
+
+Abstractions vs. bindings
+-------------------------
+
+Abstractions are Rust code wrapping kernel functionality from the C side.
+
+In order to use functions and types from the C side, bindings are created.
+Bindings are the declarations for Rust of those functions and types from
+the C side.
+
+For instance, one may write a ``Mutex`` abstraction in Rust which wraps
+a ``struct mutex`` from the C side and calls its functions through the bindings.
+
+Abstractions are not available for all the kernel internal APIs and concepts,
+but it is intended that coverage is expanded as time goes on. "Leaf" modules
+(e.g. drivers) should not use the C bindings directly. Instead, subsystems
+should provide as-safe-as-possible abstractions as needed.
+
+
+Conditional compilation
+-----------------------
+
+Rust code has access to conditional compilation based on the kernel
+configuration:
+
+.. code-block:: rust
+
+ #[cfg(CONFIG_X)] // Enabled (`y` or `m`)
+ #[cfg(CONFIG_X="y")] // Enabled as a built-in (`y`)
+ #[cfg(CONFIG_X="m")] // Enabled as a module (`m`)
+ #[cfg(not(CONFIG_X))] // Disabled

+Quick Start
+===========
+
+This document describes how to get started with kernel development in Rust.
+
+
+Requirements: Building
+----------------------
+
+This section explains how to fetch the tools needed for building.
+
+Some of these requirements might be available from Linux distributions
+under names like ``rustc``, ``rust-src``, ``rust-bindgen``, etc. However,
+at the time of writing, they are likely not to be recent enough unless
+the distribution tracks the latest releases.
+
+To easily check whether the requirements are met, the following target
+can be used::
+
+ make LLVM=1 rustavailable
+
+This triggers the same logic used by Kconfig to determine whether
+``RUST_IS_AVAILABLE`` should be enabled; but it also explains why not
+if that is the case.
+
+
+rustc
+*****
+
+A particular version of the Rust compiler is required. Newer versions may or
+may not work because, for the moment, the kernel depends on some unstable
+Rust features.
+
+If ``rustup`` is being used, enter the checked out source code directory
+and run::
+
+ rustup override set $(scripts/min-tool-version.sh rustc)
+
+Otherwise, fetch a standalone installer or install ``rustup`` from:
+
+ https://www.rust-lang.org
+
+
+Rust standard library source
+****************************
+
+The Rust standard library source is required because the build system will
+cross-compile ``core`` and ``alloc``.
+
+If ``rustup`` is being used, run::
+
+ rustup component add rust-src
+
+The components are installed per toolchain, thus upgrading the Rust compiler
+version later on requires re-adding the component.
+
+Otherwise, if a standalone installer is used, the Rust repository may be cloned
+into the installation folder of the toolchain::
+
+ git clone --recurse-submodules \
+ --branch $(scripts/min-tool-version.sh rustc) \
+ https://github.com/rust-lang/rust \
+ $(rustc --print sysroot)/lib/rustlib/src/rust
+
+In this case, upgrading the Rust compiler version later on requires manually
+updating this clone.
+
+
+libclang
+********
+
+``libclang`` (part of LLVM) is used by ``bindgen`` to understand the C code
+in the kernel, which means LLVM needs to be installed; like when the kernel
+is compiled with ``CC=clang`` or ``LLVM=1``.
+
+Linux distributions are likely to have a suitable one available, so it is
+best to check that first.
+
+There are also some binaries for several systems and architectures uploaded at:
+
+ https://releases.llvm.org/download.html
+
+Otherwise, building LLVM takes quite a while, but it is not a complex process:
+
+ https://llvm.org/docs/GettingStarted.html#getting-the-source-code-and-building-llvm
+
+Please see Documentation/kbuild/llvm.rst for more information and further ways
+to fetch pre-built releases and distribution packages.
+
+
+bindgen
+*******
+
+The bindings to the C side of the kernel are generated at build time using
+the ``bindgen`` tool. A particular version is required.
+
+Install it via (note that this will download and build the tool from source)::
+
+ cargo install --locked --version $(scripts/min-tool-version.sh bindgen) bindgen
+
+

+This section explains how to fetch the tools needed for developing. That is,
+they are not needed when just building the kernel.
+
+
+rustfmt
+*******
+
+The ``rustfmt`` tool is used to automatically format all the Rust kernel code,
+including the generated C bindings (for details, please see
+coding-guidelines.rst).
+
+If ``rustup`` is being used, its ``default`` profile already installs the tool,
+thus nothing needs to be done. If another profile is being used, the component
+can be installed manually::
+
+ rustup component add rustfmt
+
+The standalone installers also come with ``rustfmt``.
+
+
+clippy
+******
+
+``clippy`` is a Rust linter. Running it provides extra warnings for Rust code.
+It can be run by passing ``CLIPPY=1`` to ``make`` (for details, please see
+general-information.rst).
+
+If ``rustup`` is being used, its ``default`` profile already installs the tool,
+thus nothing needs to be done. If another profile is being used, the component
+can be installed manually::
+
+ rustup component add clippy
+
+The standalone installers also come with ``clippy``.
+
+
+cargo
+*****
+
+``cargo`` is the Rust native build system. It is currently required to run
+the tests since it is used to build a custom standard library that contains
+the facilities provided by the custom ``alloc`` in the kernel. The tests can
+be run using the ``rusttest`` Make target.
+
+If ``rustup`` is being used, all the profiles already install the tool,
+thus nothing needs to be done.
+
+The standalone installers also come with ``cargo``.
+
+
+rustdoc
+*******
+
+``rustdoc`` is the documentation tool for Rust. It generates pretty HTML
+documentation for Rust code (for details, please see
+general-information.rst).
+
+``rustdoc`` is also used to test the examples provided in documented Rust code
+(called doctests or documentation tests). The ``rusttest`` Make target uses
+this feature.
+
+If ``rustup`` is being used, all the profiles already install the tool,
+thus nothing needs to be done.
+
+The standalone installers also come with ``rustdoc``.
+
+
+rust-analyzer
+*************
+
+The `rust-analyzer <https://rust-analyzer.github.io/>`_ language server can
+be used with many editors to enable syntax highlighting, completion, go to
+definition, and other features.
+
+``rust-analyzer`` needs a configuration file, ``rust-project.json``, which
+can be generated by the ``rust-analyzer`` Make target.
+
+
+Configuration
+-------------
+
+``Rust support`` (``CONFIG_RUST``) needs to be enabled in the ``General setup``
+menu. The option is only shown if a suitable Rust toolchain is found (see
+above), as long as the other requirements are met. In turn, this will make
+visible the rest of options that depend on Rust.
+
+Afterwards, go to::
+
+ Kernel hacking
+ -> Sample kernel code
+ -> Rust samples
+
+And enable some sample modules either as built-in or as loadable.
+
+
+Building
+--------
+
+Building a kernel with a complete LLVM toolchain is the best supported setup
+at the moment. That is::
+
+ make LLVM=1
+
+For architectures that do not support a full LLVM toolchain, use::
+
+ make CC=clang
+
+Using GCC also works for some configurations, but it is very experimental at
+the moment.
+
+
+Hacking
+-------
+
+To dive deeper, take a look at the source code of the samples
+at ``samples/rust/``, the Rust support code under ``rust/`` and
+the ``Rust hacking`` menu under ``Kernel hacking``.
+
+If GDB/Binutils is used and Rust symbols are not getting demangled, the reason
+is the toolchain does not support Rust's new v0 mangling scheme yet.
+There are a few ways out:
+
+ - Install a newer release (GDB >= 10.2, Binutils >= 2.36).
+
+ - Some versions of GDB (e.g. vanilla GDB 10.1) are able to use
+ the pre-demangled names embedded in the debug info (``CONFIG_DEBUG_INFO``).

-
-一个 IRQ 是来自某个设备的一个中断请求。目前，它们可以来自一个硬件引脚，
-或来自一个数据包。多个设备可能连接到同个硬件引脚，从而共享一个 IRQ。
-
-一个 IRQ 编号是用于告知硬件中断源的内核标识。通常情况下，这是一个
-全局 irq_desc 数组的索引，但是除了在 linux/interrupt.h 中的实现，
-具体的细节是体系结构特定的。
-
-一个 IRQ 编号是设备上某个可能的中断源的枚举。通常情况下，枚举的编号是
-该引脚在系统内中断控制器的所有输入引脚中的编号。对于 ISA 总线中的情况，
-枚举的是在两个 i8259 中断控制器中 16 个输入引脚。
-
-架构可以对 IRQ 编号指定额外的含义，在硬件涉及任何手工配置的情况下，
-是被提倡的。ISA 的 IRQ 是一个分配这类额外含义的典型例子。

+=====================
+PCI主桥的ACPI注意事项
+=====================
+
+一般的规则是，ACPI命名空间应该描述操作系统可能使用的所有东西，除非有其他方法让操作系
+统找到它[1, 2]。
+
+例如，没有标准的硬件机制来枚举PCI主桥，所以ACPI命名空间必须描述每个主桥、访问它
+下面的PCI配置空间的方法、主桥转发到PCI的地址空间窗口（使用_CRS）以及传统的INTx
+中断的路由（使用_PRT）。
+
+在主桥下面的PCI设备，通常不需要通过ACPI描述。操作系统可以通过标准的PCI枚举机制来
+发现它们，使用配置访问来发现和识别设备，并读取和测量它们的BAR。然而，如果ACPI为它们
+提供电源管理或热插拔功能，或者如果设备有由平台中断控制器连接的INTx中断，需要一个_PRT
+来描述这些连接，这种情况下ACPI可以描述PCI设备。
+
+ACPI资源描述是通过ACPI命名空间中设备的_CRS对象完成的[2]。_CRS就像一个通用的PCI BAR：
+操作系统可以读取_CRS并找出正在消耗的资源，即使它没有该设备的驱动程序[3]。这一点很重要，
+因为它意味着一个旧的操作系统可以正确地工作，即使是在操作系统不知道的新设备的系统上。新设
+备可能什么都不做，但操作系统至少可以确保没有资源与它们冲突。
+
+像MCFG、HPET、ECDT等静态表，不是保留地址空间的机制。静态表是在操作系统在启动初期且在它
+能够解析ACPI命名空间之前需要知道的东西。如果定义了一个新的表，即使旧的操作系统忽略了这
+个表，它也需要正常运行。_CRS允许这样做，因为它是通用的，可以被旧的操作系统解析；而静态表
+则不允许。
+
+如果操作系统要管理一个通过ACPI描述的不可发现的设备，该设备将有一个特定的_HID/_CID，以
+告诉操作系统与之绑定的驱动程序，并且_CRS告诉操作系统和驱动程序该设备的寄存器在哪里。
+
+PCI主桥是PNP0A03或PNP0A08设备。它们的_CRS应该描述它们所消耗的所有地址空间。这包括它
+们转发到PCI总线上的所有窗口，以及不转发到PCI的主桥本身的寄存器。主桥的寄存器包括次要/下
+级总线寄存器，决定了桥下面的总线范围，窗口寄存器描述了桥洞，等等。这些都是设备相关的，非
+架构相关的东西，所以PNP0A03/PNP0A08驱动可以管理它们的唯一方法是通过_PRS/_CRS/_SRS，
+它包含了特定于设备的细节。主桥寄存器也包括ECAM空间，因为它是由主桥消耗的。
+
+ACPI定义了一个Consumer/Producer位来区分桥寄存器（“Consumer”下文译作消费者）和
+桥洞（“Producer”下文译作生产者）[4, 5]，但是早期的BIOS没有正确使用这个位。其结果
+是，目前的ACPI规范只为扩展地址空间描述符定义了消费者/生产者；在旧的QWord/Word/Word地
+址空间描述符中，该位应该被忽略。因此，操作系统必须假定所有的QWord/Word/Word描述符都是
+窗口。
+
+在增加扩展地址空间描述符之前，消费者/生产者的失败意味着没有办法描述PNP0A03/PNP0A08设
+备本身的桥寄存器。解决办法是在PNP0C02捕捉器中描述桥寄存器（包括ECAM空间）[6]。
+除了ECAM之外，桥寄存器空间反正是特定于设备的，所以通用的PNP0A03/PNP0A08驱动程
+序(pci_root.c)没有必要了解它。
+
+新的架构应该能够在PNP0A03设备中使用“消费者”扩展地址空间描述符，用于桥寄存器，包括
+ECAM，尽管对[6]的严格解释可能禁止这样做。旧的x86和ia64内核假定所有的地址空间描述
+符，包括“消费者”扩展地址空间的描述符，都是窗口，所以在这些架构上以这种方式描述桥寄
+存器是不安全的。
+
+PNP0C02“主板”设备基本上是万能的。除了“不要将这些资源用于其他用途”之外，没有其他的编
+程模型。因此，PNP0C02 _CRS应该声明ACPI命名空间中(1)没有被_CRS声明的任何其他设备对
+象的地址空间，(2)不应该被OS分配给其他东西。
+
+除非有一个标准的固件接口用于配置访问，例如ia64 SAL接口[7]，否则PCIe规范要求使用增强
+型配置访问方法（ECAM）。主桥消耗ECAM内存地址空间并将内存访问转换为PCI配置访问。该规范
+定义了ECAM地址空间的布局和功能；只有地址空间的基础是特定于设备的。ACPI操作系统从静态
+MCFG表或PNP0A03设备中的_CBA方法中了解基础地址。
+
+MCFG表必须描述非热插拔主桥的ECAM空间[8]。由于MCFG是一个静态表，不能通过热插拔更新，
+PNP0A03设备中的_CBA方法描述了可热插拔主桥的ECAM空间[9]。请注意，对于MCFG和_CBA，
+基址总是对应于总线0，即使桥器下面的总线范围（通过_CRS报告）不从0开始。
+
+
+[1] ACPI 6.2, sec 6.1:
+ 对于任何在非枚举类型的总线上的设备（例如，ISA总线），OSPM会枚举设备的标识符，ACPI
+ 系统固件必须为每个设备提供一个_HID对象...以使OSPM能够做到这一点。
+
+[2] ACPI 6.2, sec 3.7:
+ 操作系统枚举主板设备时，只需通过读取ACPI命名空间来寻找具有硬件ID的设备。
+
+ ACPI枚举的每个设备都包括ACPI命名空间中ACPI定义的对象，该对象报告设备可能占用的硬
+ 件资源[_PRS]，报告设备当前使用的资源[_CRS]的对象，以及配置这些资源的对象[_SRS]。
+ 这些信息被即插即用操作系统（OSPM）用来配置设备。
+
+[3] ACPI 6.2, sec 6.2:
+ OSPM使用设备配置对象来配置通过ACPI列举的设备的硬件资源。设备配置对象提供了关于当前
+ 和可能的资源需求的信息，共享资源之间的关系，以及配置硬件资源的方法。
+
+ 当OSPM枚举一个设备时，它调用_PRS来确定该设备的资源需求。它也可以调用_CRS来找到该设
+ 备的当前资源设置。利用这些信息，即插即用系统决定设备应该消耗什么资源，并通过调用设备
+ 的_SRS控制方法来设置这些资源。
+
+ 在ACPI中，设备可以消耗资源（例如，传统的键盘），提供资源（例如，一个专有的PCI桥），
+ 或者两者都做。除非另有规定，设备的资源被假定为来自设备层次结构中设备上方最近的匹配资
+ 源。
+
+[4] ACPI 6.2, sec 6.4.3.5.1, 2, 3, 4:
+ QWord/DWord/Word 地址空间描述符 (.1, .2, .3)
+ 常规标志: Bit [0] 被忽略。
+
+ 扩展地址空间描述符 (.4)
+ 常规标志: Bit [0] 消费者/生产者:
+
+ * 1 – 这个设备消费这个资源
+ * 0 – 该设备生产和消费该资源
+
+[5] ACPI 6.2, sec 19.6.43:
+ ResourceUsage指定内存范围是由这个设备（ResourceConsumer）消费还是传递给子设备
+ （ResourceProducer）。如果没有指定，那么就假定是ResourceConsumer。
+
+[6] PCI Firmware 3.2, sec 4.1.2:
+ 如果操作系统不能原生的懂得保留MMCFG区域，MMCFG区域必须由固件保留。在MCFG表中或通
+ 过_CBA方法（见第4.1.3节）报告的地址范围必须通过声明主板资源来保留。对于大多数系统，
+ 主板资源将出现在ACPI命名空间的根部（在_SB下），在一个节点的_HID为EISAID（PNP0C0
+ 2），在这种情况下的资源不应该要求在根PCI总线的_CRS。这些资源可以选择在Int15 E820
+ 或EFIGetMemoryMap中作为保留内存返回，但必须始终通过ACPI作为主板资源报告。
+
+[7] PCI Express 4.0, sec 7.2.2:
+ 对于PC兼容的系统，或者没有实现允许访问配置空间的处理器架构特定固件接口标准的系统，需
+ 要使用本节中定义的ECAM。
+
+[8] PCI Firmware 3.2, sec 4.1.2:
+ MCFG表是一个ACPI表，用于沟通的基础地址对应的非热的可移动的PCI段组范围内的PCI段组在
+ 启动时提供给操作系统。这对PC兼容系统来说是必需的。
+
+ MCFG表仅用于沟通在启动时系统可用的PCI段组对应的基址。
+
+[9] PCI Firmware 3.2, sec 4.1.3:
+ _CBA (Memory mapped Configuration Base Address) 控制方法是一个可选的ACPI对
+ 象，用于返回热插拔主桥的64位内存映射的配置基址。_CBA 返回的基址是与处理器相关的地址。
+ _CBA 控制方法被评估为一个整数。
+
+ 这个控制方法出现在主桥对象下。当_CBA方法出现在一个活动的主桥对象下时，操作系统会评
+ 估这个结构，以确定内存映射的配置基址，对应于_CRS方法中指定的总线编号范围的PCI段组。
+ 一个包含_CBA方法的ACPI命名空间对象也必须包含一个相应的_SEG方法。

+引导配置
+========
+
+:作者: Masami Hiramatsu <mhiramat@kernel.org>
+
+概述
+====
+
+引导配置扩展了现有的内核命令行，以一种更有效率的方式在引导内核时进一步支持
+键值数据。这允许管理员传递一份结构化关键字的配置文件。
+
+配置文件语法
+============
+
+引导配置文件的语法采用非常简单的键值结构。每个关键字由点连接的单词组成，键
+和值由 ``=`` 连接。值以分号（ ``;`` ）或换行符（ ``\n`` ）结尾。数组值中每
+个元素由逗号（ ``,`` ）分隔。::
+
+ KEY[.WORD[...]] = VALUE[, VALUE2[...]][;]
+
+与内核命令行语法不同，逗号和 ``=`` 周围允许有空格。
+
+关键字只允许包含字母、数字、连字符（ ``-`` ）和下划线（ ``_`` ）。值可包含
+可打印字符和空格，但分号（ ``;`` ）、换行符（ ``\n`` ）、逗号（ ``,`` ）、
+井号（ ``#`` ）和右大括号（ ``}`` ）等分隔符除外。
+
+如果你需要在值中使用这些分隔符，可以用双引号（ ``"VALUE"`` ）或单引号
+（ ``'VALUE'`` ）括起来。注意，引号无法转义。
+
+键的值可以为空或不存在。这些键用于检查该键是否存在（类似布尔值）。
+
+键值语法
+--------
+
+引导配置文件语法允许用户通过大括号合并键名部分相同的关键字。例如::
+
+ foo.bar.baz = value1
+ foo.bar.qux.quux = value2
+
+也可以写成::
+
+ foo.bar {
+ baz = value1
+ qux.quux = value2
+ }
+
+或者更紧凑一些，写成::
+
+ foo.bar { baz = value1; qux.quux = value2 }
+
+在这两种样式中，引导解析时相同的关键字都会自动合并。因此可以追加类似的树或
+键值。
+
+相同关键字的值
+--------------
+
+禁止两个或多个值或数组共享同一个关键字。例如::
+
+ foo = bar, baz
+ foo = qux # !错误! 我们不可以重定义相同的关键字
+
+如果你想要更新值，必须显式使用覆盖操作符 ``:=`` 。例如::
+
+ foo = bar, baz
+ foo := qux
+
+这样 ``foo`` 关键字的值就变成了 ``qux`` 。这对于通过添加（部分）自定义引导
+配置来覆盖默认值非常有用，免于解析默认引导配置。
+
+如果你想对现有关键字追加值作为数组成员，可以使用 ``+=`` 操作符。例如::
+
+ foo = bar, baz
+ foo += qux
+
+这样， ``foo`` 关键字就同时拥有了 ``bar`` ， ``baz`` 和 ``qux`` 。
+
+此外，父关键字下可同时存在值和子关键字。
+例如，下列配置是可行的。::
+
+ foo = value1
+ foo.bar = value2
+ foo := value3 # 这会更新foo的值。
+
+注意，裸值不能直接放进结构化关键字中，必须在大括号外定义它。例如::
+
+ foo {
+ bar = value1
+ bar {
+ baz = value2
+ qux = value3
+ }
+ }
+
+同时，关键字下值节点的顺序是固定的。如果值和子关键字同时存在，值永远是该关
+键字的第一个子节点。因此如果用户先指定子关键字，如::
+
+ foo.bar = value1
+ foo = value2
+
+则在程序（和/proc/bootconfig）中，它会按如下显示::
+
+ foo = value2
+ foo.bar = value1
+
+注释
+----
+
+配置语法接受shell脚本风格的注释。注释以井号（ ``#`` ）开始，到换行符
+（ ``\n`` ）结束。
+
+::
+
+ # comment line
+ foo = value # value is set to foo.
+ bar = 1, # 1st element
+ 2, # 2nd element
+ 3 # 3rd element
+
+会被解析为::
+
+ foo = value
+ bar = 1, 2, 3
+
+注意你不能把注释放在值和分隔符（ ``,`` 或 ``;`` ）之间。如下配置语法是错误的::
+
+ key = 1 # comment
+ ,2
+
+
+/proc/bootconfig
+================
+
+/proc/bootconfig是引导配置的用户空间接口。与/proc/cmdline不同，此文件内容以
+键值列表样式显示。
+每个键值对一行，样式如下::
+
+ KEY[.WORDS...] = "[VALUE]"[,"VALUE2"...]
+
+
+用引导配置引导内核
+==================
+
+用引导配置引导内核有两种方法：将引导配置附加到initrd镜像或直接嵌入内核中。
+
+*initrd: initial RAM disk，初始内存磁盘*
+
+将引导配置附加到initrd
+----------------------
+
+由于默认情况下引导配置文件是用initrd加载的，因此它将被添加到initrd（initramfs）
+镜像文件的末尾，其中包含填充、大小、校验值和12字节幻数，如下所示::
+
+ [initrd][bootconfig][padding][size(le32)][checksum(le32)][#BOOTCONFIG\n]
+
+大小和校验值为小端序存放的32位无符号值。
+
+当引导配置被加到initrd镜像时，整个文件大小会对齐到4字节。空字符（ ``\0`` ）
+会填补对齐空隙。因此 ``size`` 就是引导配置文件的长度+填充的字节。
+
+Linux内核在内存中解码initrd镜像的最后部分以获取引导配置数据。由于这种“背负式”
+的方法，只要引导加载器传递了正确的initrd文件大小，就无需更改或更新引导加载器
+和内核镜像本身。如果引导加载器意外传递了更长的大小，内核将无法找到引导配置数
+据。
+
+Linux内核在tools/bootconfig下提供了 ``bootconfig`` 命令来完成此操作，管理员
+可以用它从initrd镜像中删除或追加配置文件。你可以用以下命令来构建它::
+
+ # make -C tools/bootconfig
+
+要向initrd镜像添加你的引导配置文件，请按如下命令操作（旧数据会自动移除）::
+
+ # tools/bootconfig/bootconfig -a your-config /boot/initrd.img-X.Y.Z
+
+要从镜像中移除配置，可以使用-d选项::
+
+ # tools/bootconfig/bootconfig -d /boot/initrd.img-X.Y.Z
+
+然后在内核命令行上添加 ``bootconfig`` 告诉内核去initrd文件末尾寻找内核配置。
+
+将引导配置嵌入内核
+------------------
+
+如果你不能使用initrd，也可以通过Kconfig选项将引导配置文件嵌入内核中。在此情
+况下，你需要用以下选项重新编译内核::
+
+ CONFIG_BOOT_CONFIG_EMBED=y
+ CONFIG_BOOT_CONFIG_EMBED_FILE="/引导配置/文件/的/路径"
+
+``CONFIG_BOOT_CONFIG_EMBED_FILE`` 需要从源码树或对象树开始的引导配置文件的
+绝对/相对路径。内核会将其嵌入作为默认引导配置。
+
+与将引导配置附加到initrd一样，你也需要在内核命令行上添加 ``bootconfig`` 告诉
+内核去启用内嵌的引导配置。
+
+注意，即使你已经设置了此选项，仍可用附加到initrd的其他引导配置覆盖内嵌的引导
+配置。
+
+通过引导配置传递内核参数
+========================
+
+除了内核命令行，引导配置也可以用于传递内核参数。所有 ``kernel`` 关键字下的键
+值对都将直接传递给内核命令行。此外， ``init`` 下的键值对将通过命令行传递给
+init进程。参数按以下顺序与用户给定的内核命令行字符串相连，因此命令行参数可以
+覆盖引导配置参数（这取决于子系统如何处理参数，但通常前面的参数将被后面的参数
+覆盖）::
+
+ [bootconfig params][cmdline params] -- [bootconfig init params][cmdline init params]
+
+如果引导配置文件给出的kernel/init参数是::
+
+ kernel {
+ root = 01234567-89ab-cdef-0123-456789abcd
+ }
+ init {
+ splash
+ }
+
+这将被复制到内核命令行字符串中，如下所示::
+
+ root="01234567-89ab-cdef-0123-456789abcd" -- splash
+
+如果用户给出的其他命令行是::
+
+ ro bootconfig -- quiet
+
+则最后的内核命令行如下::
+
+ root="01234567-89ab-cdef-0123-456789abcd" ro bootconfig -- splash quiet
+
+
+配置文件的限制
+==============
+
+当前最大的配置大小是32KB，关键字总数（不是键值条目）必须少于1024个节点。
+注意：这不是条目数而是节点数，条目必须消耗超过2个节点（一个关键字和一个值）。
+所以从理论上讲最多512个键值对。如果关键字平均包含3个单词，则可有256个键值对。
+在大多数情况下，配置项的数量将少于100个条目，小于8KB，因此这应该足够了。如果
+节点数超过1024，解析器将返回错误，即使文件大小小于32KB。（请注意，此最大尺寸
+不包括填充的空字符。）
+无论如何，因为 ``bootconfig`` 命令在附加启动配置到initrd映像时会验证它，用户
+可以在引导之前注意到它。
+
+
+引导配置API
+===========
+
+用户可以查询或遍历键值对，也可以查找（前缀）根关键字节点，并在查找该节点下的
+键值。
+
+如果您有一个关键字字符串，则可以直接使用 xbc_find_value() 查询该键的值。如果
+你想知道引导配置里有哪些关键字，可以使用 xbc_for_each_key_value() 迭代键值对。
+请注意，您需要使用 xbc_array_for_each_value() 访问数组的值，例如::
+
+ vnode = NULL;
+ xbc_find_value("key.word", &vnode);
+ if (vnode && xbc_node_is_array(vnode))
+ xbc_array_for_each_value(vnode, value) {
+ printk("%s ", value);
+ }
+
+如果您想查找具有前缀字符串的键，可以使用 xbc_find_node() 通过前缀字符串查找
+节点，然后用 xbc_node_for_each_key_value() 迭代前缀节点下的键。
+
+但最典型的用法是获取前缀下的命名值或前缀下的命名数组，例如::
+
+ root = xbc_find_node("key.prefix");
+ value = xbc_node_find_value(root, "option", &vnode);
+ ...
+ xbc_node_for_each_array_value(root, "array-option", value, anode) {
+ ...
+ }
+
+这将访问值“key.prefix.option”的值和“key.prefix.array-option”的数组。
+
+锁是不需要的，因为在初始化之后配置只读。如果需要修改，必须复制所有数据和关键字。

+环形缓冲区
+==========
+
+:作者: David Howells <dhowells@redhat.com>
+:作者: Paul E. McKenney <paulmck@linux.ibm.com>
+
+
+Linux 提供了许多可用于实现循环缓冲的特性。有两组这样的特性：
+
+ (1) 用于确定2次方大小的缓冲区信息的便利函数。
+
+ (2) 可以代替缓冲区中对象的生产者和消费者共享锁的内存屏障。
+
+如下所述，要使用这些设施，只需要一个生产者和一个消费者。可以通过序列化来处理多个
+生产者，并通过序列化来处理多个消费者。

+
+ (*) 测量2次幂缓冲区
+
+ (*) 内存屏障与环形缓冲区的结合使用
+ - 生产者
+ - 消费者
+
+ (*) 延伸阅读
+
+
+
+什么是环形缓冲区？
+==================
+
+首先，什么是环形缓冲区？环形缓冲区是具有固定的有限大小的缓冲区，它有两个索引：
+
+ (1) 'head'索引 - 生产者将元素插入缓冲区的位置。
+
+ (2) 'tail'索引 - 消费者在缓冲区中找到下一个元素的位置。
+
+通常，当tail指针等于head指针时，表明缓冲区是空的；而当head指针比tail指针少一个时，
+表明缓冲区是满的。
+
+添加元素时，递增head索引；删除元素时，递增tail索引。tail索引不应该跳过head索引，
+两个索引在到达缓冲区末端时都应该被赋值为0，从而允许海量的数据流过缓冲区。
+
+通常情况下，元素都有相同的单元大小，但这并不是使用以下技术的严格要求。如果要在缓
+冲区中包含多个元素或可变大小的元素，则索引可以增加超过1，前提是两个索引都没有超过
+另一个。然而，实现者必须小心，因为超过一个单位大小的区域可能会覆盖缓冲区的末端并
+且缓冲区会被分成两段。
+
+测量2次幂缓冲区
+===============
+
+计算任意大小的环形缓冲区的占用或剩余容量通常是一个费时的操作，需要使用模（除法）
+指令。但是如果缓冲区的大小为2次幂，则可以使用更快的按位与指令代替。
+
+Linux提供了一组用于处理2次幂环形缓冲区的宏。可以通过以下方式使用::
+
+ #include <linux/circ_buf.h>
+
+这些宏包括：
+
+ (#) 测量缓冲区的剩余容量::
+
+ CIRC_SPACE(head_index, tail_index, buffer_size);
+
+ 返回缓冲区[1]中可插入元素的剩余空间大小。
+
+
+ (#) 测量缓冲区中的最大连续立即可用空间::
+
+ CIRC_SPACE_TO_END(head_index, tail_index, buffer_size);
+
+ 返回缓冲区[1]中剩余的连续空间的大小，元素可以立即插入其中，而不必绕回到缓冲
+ 区的开头。
+
+
+ (#) 测量缓冲区的使用数::
+
+ CIRC_CNT(head_index, tail_index, buffer_size);
+
+ 返回当前占用缓冲区[2]的元素数量。
+
+
+ (#) 测量缓冲区的连续使用数::
+
+ CIRC_CNT_TO_END(head_index, tail_index, buffer_size);
+
+ 返回可以从缓冲区中提取的连续元素[2]的数量，而不必绕回到缓冲区的开头。
+
+这里的每一个宏名义上都会返回一个介于0和buffer_size-1之间的值，但是：
+
+ (1) CIRC_SPACE*()是为了在生产者中使用。对生产者来说，它们将返回一个下限，因为生
+ 产者控制着head索引，但消费者可能仍然在另一个CPU上耗尽缓冲区并移动tail索引。
+
+ 对消费者来说，它将显示一个上限，因为生产者可能正忙于耗尽空间。
+
+ (2) CIRC_CNT*()是为了在消费者中使用。对消费者来说，它们将返回一个下限，因为消费
+ 者控制着tail索引，但生产者可能仍然在另一个CPU上填充缓冲区并移动head索引。
+
+ 对于生产者，它将显示一个上限，因为消费者可能正忙于清空缓冲区。
+
+ (3) 对于第三方来说，生产者和消费者对索引的写入顺序是无法保证的，因为它们是独立的，
+ 而且可能是在不同的CPU上进行的，所以在这种情况下的结果只是一种猜测，甚至可能
+ 是错误的。
+
+内存屏障与环形缓冲区的结合使用
+==============================
+
+通过将内存屏障与环形缓冲区结合使用，可以避免以下需求：
+
+ (1) 使用单个锁来控制对缓冲区两端的访问，从而允许同时填充和清空缓冲区；以及
+
+ (2) 使用原子计数器操作。
+
+这有两个方面：填充缓冲区的生产者和清空缓冲区的消费者。在任何时候，只应有一个生产
+者在填充缓冲区，同样的也只应有一个消费者在清空缓冲区，但双方可以同时操作。
+
+
+生产者
+------
+
+生产者看起来像这样::
+
+ spin_lock(&producer_lock);
+
+ unsigned long head = buffer->head;
+ /* spin_unlock()和下一个spin_lock()提供必要的排序。 */
+ unsigned long tail = READ_ONCE(buffer->tail);
+
+ if (CIRC_SPACE(head, tail, buffer->size) >= 1) {
+ /* 添加一个元素到缓冲区 */
+ struct item *item = buffer[head];
+
+ produce_item(item);
+
+ smp_store_release(buffer->head,
+ (head + 1) & (buffer->size - 1));
+
+ /* wake_up()将确保在唤醒任何人之前提交head */
+ wake_up(consumer);
+ }
+
+ spin_unlock(&producer_lock);
+
+这将表明CPU必须在head索引使其对消费者可用之前写入新项目的内容，同时CPU必须在唤醒
+消费者之前写入修改后的head索引。
+
+请注意，wake_up()并不保证任何形式的屏障，除非确实唤醒了某些东西。因此我们不能依靠
+它来进行排序。但是数组中始终有一个元素留空，因此生产者必须产生两个元素，然后才可
+能破坏消费者当前正在读取的元素。同时，消费者连续调用之间成对的解锁-加锁提供了索引
+读取（指示消费者已清空给定元素）和生产者对该相同元素的写入之间的必要顺序。
+
+
+消费者
+------
+
+消费者看起来像这样::
+
+ spin_lock(&consumer_lock);
+
+ /* 读取该索引处的内容之前，先读取索引 */
+ unsigned long head = smp_load_acquire(buffer->head);
+ unsigned long tail = buffer->tail;
+
+ if (CIRC_CNT(head, tail, buffer->size) >= 1) {
+
+ /* 从缓冲区中提取一个元素 */
+ struct item *item = buffer[tail];
+
+ consume_item(item);
+
+ /* 在递增tail之前完成对描述符的读取。 */
+ smp_store_release(buffer->tail,
+ (tail + 1) & (buffer->size - 1));
+ }
+
+ spin_unlock(&consumer_lock);
+
+这表明CPU在读取新元素之前确保索引是最新的，然后在写入新的尾指针之前应确保CPU已完
+成读取该元素，这将擦除该元素。
+
+请注意，使用READ_ONCE()和smp_load_acquire()来读取反向（head）索引。这可以防止编译
+器丢弃并重新加载其缓存值。如果您能确定反向（head）索引将仅使用一次，则这不是必须
+的。smp_load_acquire()还可以强制CPU对后续的内存引用进行排序。类似地，两种算法都使
+用smp_store_release()来写入线程的索引。这记录了我们正在写入可以并发读取的内容的事
+实，以防止编译器破坏存储，并强制对以前的访问进行排序。

+IDR接口已经被废弃，请使用 ``XArray`` 。
+
+IDR的用法
+=========
+
+首先初始化一个IDR，对于静态分配的IDR使用DEFINE_IDR()，或者对于动态分配的IDR使用
+idr_init()。
+
+您可以调用idr_alloc()来分配一个未使用的ID。通过调用idr_find()查询与该ID相关的指针，
+并通过调用idr_remove()释放该ID。
+
+如果需要更改与一个ID相关联的指针，可以调用idr_replace()。这样做的一个常见原因是通
+过将 ``NULL`` 指针传递给分配函数来保留ID；用保留的ID初始化对象，最后将初始化的对
+象插入IDR。
+
+一些用户需要分配大于 ``INT_MAX`` 的ID。到目前为止，所有这些用户都满足 ``UINT_MAX``
+的限制，他们使用idr_alloc_u32()。如果您需要超出u32的ID，我们将与您合作以满足您的
+需求。
+
+如果需要按顺序分配ID，可以使用idr_alloc_cyclic()。处理较大数量的ID时，IDR的效率会
+降低，所以使用这个函数会有一点代价。
+
+要对IDR使用的所有指针进行操作，您可以使用基于回调的idr_for_each()或迭代器样式的
+idr_for_each_entry()。您可能需要使用idr_for_each_entry_continue()来继续迭代。如果
+迭代器不符合您的需求，您也可以使用idr_get_next()。
+
+当使用完IDR后，您可以调用idr_destroy()来释放IDR占用的内存。这并不会释放IDR指向的
+对象；如果您想这样做，请使用其中一个迭代器来执行此操作。
+
+您可以使用idr_is_empty()来查看当前是否分配了任何ID。
+
+如果在从IDR分配一个新ID时需要带锁，您可能需要传递一组限制性的GFP标志，但这可能导
+致IDR无法分配内存。为了解决该问题，您可以在获取锁之前调用idr_preload()，然后在分
+配之后调用idr_preload_end()。

+========================
+通用的位域打包和解包函数
+========================
+
+问题陈述
+--------
+
+使用硬件时，必须在几种与其交互的方法之间进行选择。
+
+可以将指针映射到在硬件设备的内存区上精心设计的结构体，并将其字段作为结构成员（可
+能声明为位域）访问。但是由于CPU和硬件设备之间潜在的字节顺序不匹配，以这种方式编写
+代码会降低其可移植性。
+
+此外，必须密切注意将硬件文档中的寄存器定义转换为结构的位域索引。此外，一些硬件
+（通常是网络设备）倾向于以违反任何合理字边界（有时甚至是64位）的方式对其寄存器字
+段进行分组。这就造成了不得不在结构中定义寄存器字段的“高”和“低”部分的不便。
+
+结构域定义的更可靠的替代方法是通过移动适当数量的位来提取所需的字段。但这仍然不能
+防止字节顺序不匹配，除非所有内存访问都是逐字节执行的。此外，代码很容易变得杂乱无
+章，同时可能会在所需的许多位移操作中丢失一些高层次的想法。
+
+许多驱动程序采用了位移的方法，然后试图用定制的宏来减少杂乱无章的东西，但更多的时
+候，这些宏所采用的捷径依旧妨碍了代码真正的可移植性。
+
+解决方案
+--------
+
+该API涉及2个基本操作：
+
+ - 将一个CPU可使用的数字打包到内存缓冲区中（具有硬件约束/特殊性）。
+ - 将内存缓冲区（具有硬件约束/特殊性）解压缩为一个CPU可使用的数字。
+
+该API提供了对所述硬件约束和特殊性以及CPU字节序的抽象，因此这两者之间可能不匹配。
+
+这些API函数的基本单元是u64。从CPU的角度来看，位63总是意味着字节7的位偏移量7，尽管
+只是逻辑上的。问题是：我们将这个比特放在内存的什么位置？
+
+以下示例介绍了打包u64字段的内存布局。打包缓冲区中的字节偏移量始终默认为0，1...7。
+示例显示的是逻辑字节和位所在的位置。
+
+1. 通常情况下（无特殊性），我们会这样做：
+
+::
+
+ 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32
+ 7 6 5 4
+ 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
+ 3 2 1 0
+
+也就是说，CPU可使用的u64的MSByte(7)位于内存偏移量0处，而u64的LSByte(0)位于内存偏移量7处。
+
+这对应于大多数人认为的“大端”，其中位i对应于数字2^i。这在代码注释中也称为“逻辑”符号。
+
+
+2. 如果设置了QUIRK_MSB_ON_THE_RIGHT，我们按如下方式操作：
+
+::
+
+ 56 57 58 59 60 61 62 63 48 49 50 51 52 53 54 55 40 41 42 43 44 45 46 47 32 33 34 35 36 37 38 39
+ 7 6 5 4
+ 24 25 26 27 28 29 30 31 16 17 18 19 20 21 22 23 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7
+ 3 2 1 0
+
+也就是说，QUIRK_MSB_ON_THE_RIGHT不会影响字节定位，但会反转字节内的位偏移量。
+
+
+3. 如果设置了QUIRK_LITTLE_ENDIAN，我们按如下方式操作：
+
+::
+
+ 39 38 37 36 35 34 33 32 47 46 45 44 43 42 41 40 55 54 53 52 51 50 49 48 63 62 61 60 59 58 57 56
+ 4 5 6 7
+ 7 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8 23 22 21 20 19 18 17 16 31 30 29 28 27 26 25 24
+ 0 1 2 3
+
+因此，QUIRK_LITTLE_ENDIAN意味着在内存区域内，每个4字节的字的每个字节都被放置在与
+该字的边界相比的镜像位置。
+
+
+4. 如果设置了QUIRK_MSB_ON_THE_RIGHT和QUIRK_LITTLE_ENDIAN，我们这样做：
+
+::
+
+ 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63
+ 4 5 6 7
+ 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
+ 0 1 2 3
+
+
+5. 如果只设置了QUIRK_LSW32_IS_FIRST，我们这样做：
+
+::
+
+ 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
+ 3 2 1 0
+ 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32
+ 7 6 5 4
+
+在这种情况下，8字节内存区域解释如下：前4字节对应最不重要的4字节的字，后4字节对应
+更重要的4字节的字。
+
+6. 如果设置了QUIRK_LSW32_IS_FIRST和QUIRK_MSB_ON_THE_RIGHT，我们这样做：
+
+::
+
+ 24 25 26 27 28 29 30 31 16 17 18 19 20 21 22 23 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7
+ 3 2 1 0
+ 56 57 58 59 60 61 62 63 48 49 50 51 52 53 54 55 40 41 42 43 44 45 46 47 32 33 34 35 36 37 38 39
+ 7 6 5 4
+
+
+7. 如果设置了QUIRK_LSW32_IS_FIRST和QUIRK_LITTLE_ENDIAN，则如下所示：
+
+::
+
+ 7 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8 23 22 21 20 19 18 17 16 31 30 29 28 27 26 25 24
+ 0 1 2 3
+ 39 38 37 36 35 34 33 32 47 46 45 44 43 42 41 40 55 54 53 52 51 50 49 48 63 62 61 60 59 58 57 56
+ 4 5 6 7
+
+
+8. 如果设置了QUIRK_LSW32_IS_FIRST，QUIRK_LITTLE_ENDIAN和QUIRK_MSB_ON_THE_RIGHT，
+ 则如下所示：
+
+::
+
+ 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
+ 0 1 2 3
+ 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63
+ 4 5 6 7
+
+
+我们总是认为我们的偏移量好像没有特殊性，然后在访问内存区域之前翻译它们。
+
+预期用途
+--------
+
+选择使用该API的驱动程序首先需要确定上述3种quirk组合（共8种）中的哪一种与硬件文档
+中描述的相匹配。然后，他们应该封装packing()函数，创建一个新的xxx_packing()，使用
+适当的QUIRK_* one-hot 位集合来调用它。
+
+packing()函数返回一个int类型的错误码，以防止程序员使用不正确的API。这些错误预计不
+会在运行时发生，因此xxx_packing()返回void并简单地接受这些错误是合理的。它可以选择
+转储栈或打印错误描述。

+Devicetree动态解析器说明
+========================
+
+本文描述了内核内DeviceTree解析器的实现，它位于drivers/of/resolver.c中。
+
+解析器如何工作？
+----------------
+
+解析器被赋予一个任意的树作为输入，该树用适当的dtc选项编译，并有一个/plugin/标签。这就产
+生了适当的__fixups__和__local_fixups__节点。
+
+解析器依次通过以下步骤工作:
+
+1. 从实时树中获取最大的设备树phandle值 + 1.
+2. 调整树的所有本地 phandles，以解决这个量。
+3. 使用 __local__fixups__ 节点信息以相同的量调整所有本地引用。
+4. 对于__fixups__节点中的每个属性，找到它在实时树中引用的节点。这是用来标记该节点的标签。
+5. 检索fixup的目标的phandle。
+6. 对于属性中的每个fixup，找到节点:属性:偏移的位置，并用phandle值替换它。

+设备树覆盖说明
+==============
+
+本文档描述了drivers/of/overlay.c中的内核内设备树覆盖功能的实现，是
+Documentation/devicetree/dynamic-resolution-notes.rst[1]的配套文档。
+
+覆盖如何工作
+------------
+
+设备树覆盖的目的是修改内核的实时树，并使修改以反映变化的方式影响内核的状态。
+由于内核主要处理的是设备，任何新的设备节点如果导致一个活动的设备，就应该创建它，
+而如果设备节点被禁用或被全部删除，受影响的设备应该被取消注册。
+
+让我们举个例子，我们有一个foo板，它的基本树形图如下::
+
+ ---- foo.dts ---------------------------------------------------------------
+ /* FOO平台 */
+ /dts-v1/;
+ / {
+ compatible = "corp,foo";
+
+ /* 共享的资源 */
+ res: res {
+ };
+
+ /* 芯片上的外围设备 */
+ ocp: ocp {
+ /* 总是被实例化的外围设备 */
+ peripheral1 { ... };
+ };
+ };
+ ---- foo.dts ---------------------------------------------------------------
+
+覆盖bar.dts,
+::
+
+ ---- bar.dts - 按标签覆盖目标位置 ----------------------------
+ /dts-v1/;
+ /插件/;
+ &ocp {
+ /* bar外围 */
+ bar {
+ compatible = "corp,bar";
+ ... /* 各种属性和子节点 */
+ };
+ };
+ ---- bar.dts ---------------------------------------------------------------
+
+当加载（并按照[1]中描述的方式解决）时，应该产生foo+bar.dts::
+
+ ---- foo+bar.dts -----------------------------------------------------------
+ /* FOO平台 + bar外围 */
+ / {
+ compatible = "corp,foo";
+
+ /* 共享资源 */
+ res: res {
+ };
+
+ /* 芯片上的外围设备 */
+ ocp: ocp {
+ /* 总是被实例化的外围设备 */
+ peripheral1 { ... };
+
+ /* bar外围 */
+ bar {
+ compatible = "corp,bar";
+ ... /* 各种属性和子节点 */
+ };
+ };
+ };
+ ---- foo+bar.dts -----------------------------------------------------------
+
+作为覆盖的结果，已经创建了一个新的设备节点（bar），因此将注册一个bar平台设备，
+如果加载了匹配的设备驱动程序，将按预期创建设备。
+
+如果基础DT不是用-@选项编译的，那么“&ocp”标签将不能用于将覆盖节点解析到基础
+DT中的适当位置。在这种情况下，可以提供目标路径。通过标签的目标位置的语法是比
+较好的，因为不管标签在DT中出现在哪里，覆盖都可以被应用到任何包含标签的基础DT上。
+
+上面的bar.dts例子被修改为使用目标路径语法，即为::
+
+ ---- bar.dts - 通过明确的路径覆盖目标位置 --------------------
+ /dts-v1/;
+ /插件/;
+ &{/ocp} {
+ /* bar外围 */
+ bar {
+ compatible = "corp,bar";
+ ... /* 各种外围设备和子节点 */
+ }
+ };
+ ---- bar.dts ---------------------------------------------------------------
+
+
+内核中关于覆盖的API
+-------------------
+
+该API相当容易使用。
+
+1) 调用of_overlay_fdt_apply()来创建和应用一个覆盖的变更集。返回值是一个
+ 错误或一个识别这个覆盖的cookie。
+
+2) 调用of_overlay_remove()来删除和清理先前通过调用of_overlay_fdt_apply()
+ 而创建的覆盖变更集。不允许删除一个被另一个覆盖的覆盖变化集。
+
+最后，如果你需要一次性删除所有的覆盖，只需调用of_overlay_remove_all()，
+它将以正确的顺序删除每一个覆盖。
+
+你可以选择注册在覆盖操作中被调用的通知器。详见
+of_overlay_notifier_register/unregister和enum of_overlay_notify_action。
+
+OF_OVERLAY_PRE_APPLY、OF_OVERLAY_POST_APPLY或OF_OVERLAY_PRE_REMOVE
+的通知器回调可以存储指向覆盖层中的设备树节点或其内容的指针，但这些指针不能持
+续到OF_OVERLAY_POST_REMOVE的通知器回调。在OF_OVERLAY_POST_REMOVE通
+知器被调用后，包含覆盖层的内存将被kfree()ed。请注意，即使OF_OVERLAY_POST_REMOVE
+的通知器返回错误，内存也会被kfree()ed。
+
+drivers/of/dynamic.c中的变更集通知器是第二种类型的通知器，可以通过应用或移除
+覆盖层来触发。这些通知器不允许在覆盖层或其内容中存储指向设备树节点的指针。当包含
+覆盖层的内存因移除覆盖层而被释放时，覆盖层代码并不能防止这类指针仍然有效。
+
+任何其他保留指向覆盖层节点或数据的指针的代码都被认为是一个错误，因为在移除覆盖层
+后，该指针将指向已释放的内存。
+
+覆盖层的用户必须特别注意系统上发生的整体操作，以确保其他内核代码不保留任何指向覆
+盖层节点或数据的指针。任何无意中使用这种指针的例子是，如果一个驱动或子系统模块在
+应用了覆盖后被加载，并且该驱动或子系统扫描了整个设备树或其大部分，包括覆盖节点。

+GPIO控制器和引脚控制子系统
+--------------------------
-这些公约忽略了什么?
-================
+SOC上的GPIO控制器可能与引脚控制子系统紧密结合，即引脚可以与可选的gpio功
+能一起被其他功能使用。我们已经涵盖了这样的情况，例如一个GPIO控制器需要保
+留一个引脚或通过调用以下任何一个引脚来设置其方向::
+
+ pinctrl_gpio_request()
+ pinctrl_gpio_free()
+ pinctrl_gpio_direction_input()
+ pinctrl_gpio_direction_output()
+
+但是，引脚控制子系统是如何将GPIO号码（这是一个全局事项）与某个引脚控制器
+上的某个引脚交叉关联的？
+
+这是通过注册引脚的“范围”来实现的，这基本上是交叉参考表。这些描述是在
+Documentation/driver-api/pin-control.rst
+
+虽然引脚分配完全由引脚控制子系统管理，但gpio（在gpiolib下）仍由gpio驱动
+维护。可能发生的情况是，SoC中的不同引脚范围由不同的gpio驱动器管理。
+
+这使得在调用 "pinctrl_gpio_request" 之前，让gpio驱动向pin ctrl子系
+统宣布它们的引脚范围是合理的，以便在使用任何gpio之前要求引脚控制子系统准
+备相应的引脚。
+
+为此，gpio控制器可以用引脚控制子系统注册其引脚范围。目前有两种方法：有或
+无DT。
+
+关于对DT的支持，请参考 Documentation/devicetree/bindings/gpio/gpio.txt.
+
+对于非DT支持，用户可以用适当的参数调用gpiochip_add_pin_range()，将一

+保证I/O内存映射地址的写操作按程序图意的顺序达到设备。通常读取一个“安全”
+设备寄存器或桥寄存器，触发IO芯片清刷未处理的写操作到达设备后才处理读操作，
+而达到保证目的。驱动程序通常在spinlock保护的临界区退出之前使用这种技术。
+这也可以保证后面的写操作只在前面的写操作之后到达设备（这非常类似于内存
+屏障操作，mb()，不过仅适用于I/O）。
+
+假设一个设备驱动程的具体例子::
+
+ ...
+ CPU A: spin_lock_irqsave(&dev_lock, flags)
+ CPU A: val = readl(my_status);
+ CPU A: ...
+ CPU A: writel(newval, ring_ptr);
+ CPU A: spin_unlock_irqrestore(&dev_lock, flags)
+ ...
+ CPU B: spin_lock_irqsave(&dev_lock, flags)
+ CPU B: val = readl(my_status);
+ CPU B: ...
+ CPU B: writel(newval2, ring_ptr);
+ CPU B: spin_unlock_irqrestore(&dev_lock, flags)
+ ...
+
+上述例子中，设备可能会先接收到newval2的值，然后接收到newval的值，问题就
+发生了。不过很容易通过下面方法来修复::
+
+ ...
+ CPU A: spin_lock_irqsave(&dev_lock, flags)
+ CPU A: val = readl(my_status);
+ CPU A: ...
+ CPU A: writel(newval, ring_ptr);

+ CPU B: writel(newval2, ring_ptr);
+ CPU B: (void)readl(safe_register); /* 配置寄存器？*/
+ CPU B: spin_unlock_irqrestore(&dev_lock, flags)
+
+在解决方案中，读取safe_register寄存器，触发IO芯片清刷未处理的写操作，
+再处理后面的读操作，防止引发数据不一致问题。

-快速总结
--------------
-
-发现Oops并发送给看似相关的内核领域的维护者。别太担心对不上号。如果你不确定就发给
-和你所做的事情相关的代码的负责人。 如果可重现试着描述怎样重构。 那甚至比oops更有
-价值。
-
-如果你对于发送给谁一无所知， 发给linux-kernel@vger.kernel.org。感谢你帮助Linux
-尽可能地稳定。

-Oops在哪里?
-----------------------
-
-通常Oops文本由klogd从内核缓冲区里读取并传给syslogd，由syslogd写到syslog文件中，
-典型地是/var/log/messages(依赖于/etc/syslog.conf)。有时klogd崩溃了,这种情况下你
-能够运行dmesg > file来从内核缓冲区中读取数据并保存下来。 否则你可以
-cat /proc/kmsg > file， 然而你必须介入中止传输， kmsg是一个“永不结束的文件”。如
-果机器崩溃坏到你不能输入命令或者磁盘不可用那么你有三种选择:-
-
-（1） 手抄屏幕上的文本待机器重启后再输入计算机。 麻烦但如果没有针对崩溃的准备，
-这是仅有的选择。 另外，你可以用数码相机把屏幕拍下来-不太好，但比没有强。 如果信
-息滚动到了终端的上面，你会发现以高分辩率启动（比如，vga=791）会让你读到更多的文
-本。（注意：这需要vesafb，所以对‘早期’的oops没有帮助）
-
-（2）用串口终端启动（请参看Documentation/admin-guide/serial-console.rst），运行一个null
-modem到另一台机器并用你喜欢的通讯工具获取输出。Minicom工作地很好。
-
-（3）使用Kdump（请参看Documentation/admin-guide/kdump/kdump.rst），
-使用在Documentation/admin-guide/kdump/gdbmacros.txt中定义的dmesg gdb宏，从旧的内存中提取内核
-环形缓冲区。

-
-怎样跟踪Oops.. [原发到linux-kernel的一封邮件]
-
-主要的窍门是有五年和这些烦人的oops消息打交道的经验;-)
-
-实际上，你有办法使它更简单。我有两个不同的方法：
-
- gdb /usr/src/linux/vmlinux
- gdb> disassemble <offending_function>
-
-那是发现问题的简单办法，至少如果bug报告做的好的情况下（象这个一样-运行ksymoops
-得到oops发生的函数及函数内的偏移）。
-
-哦，如果报告发生的内核以相同的编译器和相似的配置编译它会有帮助的。
-
-另一件要做的事是反汇编bug报告的“Code”部分：ksymoops也会用正确的工具来做这件事，
-但如果没有那些工具你可以写一个傻程序：
-
- char str[] = "\xXX\xXX\xXX...";
- main(){}
-
-并用gcc -g编译它然后执行“disassemble str”（XX部分是由Oops报告的值-你可以仅剪切
-粘贴并用“\x”替换空格-我就是这么做的，因为我懒得写程序自动做这一切）。
-
-另外，你可以用scripts/decodecode这个shell脚本。它的使用方法是：
-decodecode < oops.txt
-
-“Code”之后的十六进制字节可能（在某些架构上）有一些当前指令之前的指令字节以及
-当前和之后的指令字节
-
-Code: f9 0f 8d f9 00 00 00 8d 42 0c e8 dd 26 11 c7 a1 60 ea 2b f9 8b 50 08 a1
-64 ea 2b f9 8d 34 82 8b 1e 85 db 74 6d 8b 15 60 ea 2b f9 <8b> 43 04 39 42 54
-7e 04 40 89 42 54 8b 43 04 3b 05 00 f6 52 c0
-
-最后，如果你想知道代码来自哪里，你可以：
-
- cd /usr/src/linux
- make fs/buffer.s # 或任何产生BUG的文件
-
-然后你会比gdb反汇编更清楚的知道发生了什么。
-
-现在，问题是把你所拥有的所有数据结合起来：C源码（关于它应该怎样的一般知识），
-汇编代码及其反汇编得到的代码（另外还有从“oops”消息得到的寄存器状态-对了解毁坏的
-指针有用，而且当你有了汇编代码你也能拿其它的寄存器和任何它们对应的C表达式做匹配
-）。
-
-实际上，你仅需看看哪里不匹配（这个例子是“Code”反汇编和编译器生成的代码不匹配）。
-然后你须要找出为什么不匹配。通常很简单-你看到代码使用了空指针然后你看代码想知道
-空指针是怎么出现的，还有检查它是否合法..
-
-现在，如果明白这是一项耗时的工作而且需要一丁点儿的专心，没错。这就是我为什么大多
-只是忽略那些没有符号表信息的崩溃报告的原因：简单的说太难查找了（我有一些
-程序用于在内核代码段中搜索特定的模式，而且有时我也已经能找出那些崩溃的地方，但是
-仅仅是找出正确的序列也确实需要相当扎实的内核知识）
-
-_有时_会发生这种情况，我仅看到崩溃中的反汇编代码序列， 然后我马上就明白问题出在
-哪里。这时我才意识到自己干这个工作已经太长时间了;-)

----------------------------------------------------------------------------
-关于Oops跟踪的注解：
-
-为了帮助Linus和其它内核开发者，klogd纳入了大量的支持来处理保护错误。为了拥有对
-地址解析的完整支持至少应该使用1.3-pl3的sysklogd包。
-
-当保护错误发生时，klogd守护进程自动把内核日志信息中的重要地址翻译成它们相应的符
-号。
-
-klogd执行两种类型的地址解析。首先是静态翻译其次是动态翻译。静态翻译和ksymoops
-一样使用System.map文件。为了做静态翻译klogd守护进程必须在初始化时能找到system
-map文件。关于klogd怎样搜索map文件请参看klogd手册页。
-
-动态地址翻译在使用内核可装载模块时很重要。 因为内核模块的内存是从内核动态内存池
-里分配的，所以不管是模块开始位置还是模块中函数和符号的位置都不是固定的。
-
-内核支持允许程序决定装载哪些模块和它们在内存中位置的系统调用。使用这些系统调用
-klogd守护进程生成一张符号表用于调试发生在可装载模块中的保护错误。
-
-至少klogd会提供产生保护错误的模块名。还可有额外的符号信息供可装载模块开发者选择
-以从模块中输出符号信息。
-
-因为内核模块环境可能是动态的，所以必须有一种机制当模块环境发生改变时来通知klogd
-守护进程。 有一些可用的命令行选项允许klogd向当前执行中的守护进程发送信号，告知符
-号信息应该被刷新了。 更多信息请参看klogd手册页。
-
-sysklogd发布时包含一个补丁修改了modules-2.0.0包，无论何时一个模块装载或者卸载都
-会自动向klogd发送信号。打上这个补丁提供了必要的对调试发生于内核可装载模块的保护
-错误的无缝支持。
-
-以下是被klogd处理过的发生在可装载模块中的一个保护错误例子：

-17) 不要重新发明内核宏
-------------------------------
+Linux内核布尔（bool）类型是C99 _Bool类型的别名。布尔值只能为0或1，而对布尔的
+隐式或显式转换将自动将值转换为true或false。在使用布尔类型时 **不需要** 构造，
+它会消除一类错误。
+
+使用布尔值时，应使用true和false定义，而不是1和0。

+布尔函数返回类型和堆栈变量总是可以在适当的时候使用。鼓励使用布尔来提高可读性，
+并且布尔值在存储时通常比“int”更好。
+
+如果缓存行布局或值的大小很重要，请不要使用布尔，因为其大小和对齐方式根据编译
+的体系结构而不同。针对对齐和大小进行优化的结构体不应使用布尔。
+
+如果一个结构体有多个true/false值，请考虑将它们合并为具有1比特成员的位域，或使

+
+类似地，对于函数参数，多个true/false值可以合并为单个按位的“标志”参数，如果调

+
+ 请注意，“External Editor”要求你的编辑器不能fork，换句话说，编辑器必须在

+
+- 修改你的Thunderbird设置，不要使用 ``format=flowed`` ！
+ 回到主窗口，按照
+ :menuselection:`主菜单-->首选项-->常规-->配置编辑器...`
+ 打开Thunderbird的配置编辑器。
+
+ - 将 ``mailnews.send_plaintext_flowed`` 设为 ``false``

+统的 **T:** 项以查找该树，或者直接询问维护者该树是否未在其中列出。
-仍然可以通过tarballs下载内核版本（如下一节所述），但这是进行内核开发的
-一种困难的方式。
+.. _zh_describe_changes:
-1) "diff -up"
--------------
-
-使用 "diff -up" 或者 "diff -uprN" 来创建补丁。
-
-所有内核的改动，都是以补丁的形式呈现的，补丁由 diff(1) 生成。创建补丁的
-时候，要确认它是以 "unified diff" 格式创建的，这种格式由 diff(1) 的 '-u'
-参数生成。而且，请使用 '-p' 参数，那样会显示每个改动所在的C函数，使得
-产生的补丁容易读得多。补丁应该基于内核源代码树的根目录，而不是里边的任
-何子目录。
-
-为一个单独的文件创建补丁，一般来说这样做就够了::
-
- SRCTREE=linux
- MYFILE=drivers/net/mydriver.c
-
- cd $SRCTREE
- cp $MYFILE $MYFILE.orig
- vi $MYFILE # make your change
- cd ..
- diff -up $SRCTREE/$MYFILE{.orig,} > /tmp/patch
-
-为多个文件创建补丁，你可以解开一个没有修改过的内核源代码树，然后和你自
-己的代码树之间做 diff 。例如::
-
- MYSRC=/devel/linux
-
- tar xvfz linux-3.19.tar.gz
- mv linux-3.19 linux-3.19-vanilla
- diff -uprN -X linux-3.19-vanilla/Documentation/dontdiff \
- linux-3.19-vanilla $MYSRC > /tmp/patch
-
-"dontdiff" 是内核在编译的时候产生的文件的列表，列表中的文件在 diff(1)
-产生的补丁里会被跳过。
-
-确定你的补丁里没有包含任何不属于这次补丁提交的额外文件。记得在用diff(1)
-生成补丁之后，审阅一次补丁，以确保准确。
-
-如果你的改动很散乱，你应该研究一下如何将补丁分割成独立的部分，将改动分
-割成一系列合乎逻辑的步骤。这样更容易让其他内核开发者审核，如果你想你的
-补丁被接受，这是很重要的。请参阅：
-:ref:`cn_split_changes`
-
-如果你用 ``git`` , ``git rebase -i`` 可以帮助你这一点。如果你不用 ``git``,

+回复审阅意见
+------------
+
+你的补丁几乎肯定会得到审阅者对补丁改进方法的评论（以回复邮件的形式）。您必须
+对这些评论作出回应；让补丁被忽略的一个好办法就是忽略审阅者的意见。直接回复邮
+件来回应意见即可。不会导致代码更改的意见或问题几乎肯定会带来注释或变更日志的
+改变，以便下一个审阅者更好地了解正在发生的事情。
+
+一定要告诉审阅者你在做什么改变，并感谢他们的时间。代码审阅是一个累人且耗时的
+过程，审阅者有时会变得暴躁。即使在这种情况下，也要礼貌地回应并解决他们指出的
+问题。当发送下一版时，在封面邮件或独立补丁里加上 ``patch changelog`` 说明与
+前一版本的不同之处（参见 :ref:`zh_the_canonical_patch_format` ）。

-为了加强对谁做了何事的追踪，尤其是对那些透过好几层的维护者的补丁，我们

+
+“签署”是在补丁注释最后的一行简单文字，认证你编写了它或者其他

+中的什么位置通常很有用。这对于自动化持续集成流水（CI）特别有用，这些流水线试

-pull 请求还应该包含一条整体消息，说明请求中将包含什么，一个补丁本身的 ``Git shortlog``

-一些维护人员（包括Linus）希望看到来自已签名提交的请求；这增加了他们对你的
-请求信心。特别是，在没有签名标签的情况下，Linus 不会从像 Github 这样的公共
-托管站点拉请求。
+有关此选项的更多信息，请参阅 ``man git-format-patch`` 。
-创建此类签名的第一步是生成一个 GNRPG 密钥，并由一个或多个核心内核开发人员对
-其进行签名。这一步对新开发人员来说可能很困难，但没有办法绕过它。参加会议是
-找到可以签署您的密钥的开发人员的好方法。
+.. note::
-一旦您在Git 中准备了一个您希望有人拉的补丁系列，就用 ``git tag -s`` 创建一
-个签名标记。这将创建一个新标记，标识该系列中的最后一次提交，并包含用您的私
-钥创建的签名。您还可以将changelog样式的消息添加到标记中；这是一个描述拉请求
-整体效果的理想位置。
+ ``--base`` 功能是在2.9.0版git中引入的。
-如果维护人员将要从中提取的树不是您正在使用的存储库，请不要忘记将已签名的标记
-显式推送到公共树。
-
-生成拉请求时，请使用已签名的标记作为目标。这样的命令可以实现::
-
- git request-pull master git://my.public.tree/linux.git my-signed-tag
+如果您不使用git格式化补丁，仍然可以包含相同的 ``base-commit`` 尾注，以指示您

-
-注意： ksymoops 在2.6中是沒有用的。 請以原有格式使用Oops(來自dmesg，等等)。
-忽略任何這樣那樣關於「解碼Oops」或者「通過ksymoops運行」的文檔。 如果你貼出運行過
-ksymoops的來自2.6的Oops，人們只會讓你重貼一次。
-
-快速總結
--------------
-
-發現Oops並發送給看似相關的內核領域的維護者。別太擔心對不上號。如果你不確定就發給
-和你所做的事情相關的代碼的負責人。 如果可重現試著描述怎樣重構。 那甚至比oops更有
-價值。
-
-如果你對於發送給誰一無所知， 發給linux-kernel@vger.kernel.org。感謝你幫助Linux
-儘可能地穩定。
-
-Oops在哪裡?
-----------------------
-
-通常Oops文本由klogd從內核緩衝區里讀取並傳給syslogd，由syslogd寫到syslog文件中，
-典型地是/var/log/messages(依賴於/etc/syslog.conf)。有時klogd崩潰了,這種情況下你
-能夠運行dmesg > file來從內核緩衝區中讀取數據並保存下來。 否則你可以
-cat /proc/kmsg > file， 然而你必須介入中止傳輸， kmsg是一個「永不結束的文件」。如
-果機器崩潰壞到你不能輸入命令或者磁碟不可用那麼你有三種選擇:-
-
-（1） 手抄屏幕上的文本待機器重啓後再輸入計算機。 麻煩但如果沒有針對崩潰的準備，
-這是僅有的選擇。 另外，你可以用數位相機把屏幕拍下來-不太好，但比沒有強。 如果信
-息滾動到了終端的上面，你會發現以高分辯率啓動（比如，vga=791）會讓你讀到更多的文
-本。（注意：這需要vesafb，所以對『早期』的oops沒有幫助）
-
-（2）用串口終端啓動（請參看Documentation/admin-guide/serial-console.rst），運行一個null
-modem到另一台機器並用你喜歡的通訊工具獲取輸出。Minicom工作地很好。
-
-（3）使用Kdump（請參看Documentation/admin-guide/kdump/kdump.rst），
-使用在Documentation/admin-guide/kdump/gdbmacros.txt中定義的dmesg gdb宏，從舊的內存中提取內核
-環形緩衝區。
-
-完整信息
-----------------
-
-注意：以下來自於Linus的郵件適用於2.4內核。 我因爲歷史原因保留了它，並且因爲其中
-一些信息仍然適用。 特別注意的是，請忽略任何ksymoops的引用。
-
-From: Linus Torvalds <torvalds@osdl.org>
-
-怎樣跟蹤Oops.. [原發到linux-kernel的一封郵件]
-
-主要的竅門是有五年和這些煩人的oops消息打交道的經驗;-)
-
-實際上，你有辦法使它更簡單。我有兩個不同的方法：
-
- gdb /usr/src/linux/vmlinux
- gdb> disassemble <offending_function>
-
-那是發現問題的簡單辦法，至少如果bug報告做的好的情況下（象這個一樣-運行ksymoops
-得到oops發生的函數及函數內的偏移）。
-
-哦，如果報告發生的內核以相同的編譯器和相似的配置編譯它會有幫助的。
-
-另一件要做的事是反彙編bug報告的「Code」部分：ksymoops也會用正確的工具來做這件事，
-但如果沒有那些工具你可以寫一個傻程序：
-
- char str[] = "\xXX\xXX\xXX...";
- main(){}
-
-並用gcc -g編譯它然後執行「disassemble str」（XX部分是由Oops報告的值-你可以僅剪切
-粘貼並用「\x」替換空格-我就是這麼做的，因爲我懶得寫程序自動做這一切）。
-
-另外，你可以用scripts/decodecode這個shell腳本。它的使用方法是：
-decodecode < oops.txt
-
-「Code」之後的十六進位字節可能（在某些架構上）有一些當前指令之前的指令字節以及
-當前和之後的指令字節
-
-Code: f9 0f 8d f9 00 00 00 8d 42 0c e8 dd 26 11 c7 a1 60 ea 2b f9 8b 50 08 a1
-64 ea 2b f9 8d 34 82 8b 1e 85 db 74 6d 8b 15 60 ea 2b f9 <8b> 43 04 39 42 54
-7e 04 40 89 42 54 8b 43 04 3b 05 00 f6 52 c0
-
-最後，如果你想知道代碼來自哪裡，你可以：
-
- cd /usr/src/linux
- make fs/buffer.s # 或任何產生BUG的文件
-
-然後你會比gdb反彙編更清楚的知道發生了什麼。
-
-現在，問題是把你所擁有的所有數據結合起來：C源碼（關於它應該怎樣的一般知識），
-彙編代碼及其反彙編得到的代碼（另外還有從「oops」消息得到的寄存器狀態-對了解毀壞的
-指針有用，而且當你有了彙編代碼你也能拿其它的寄存器和任何它們對應的C表達式做匹配
-）。
-
-實際上，你僅需看看哪裡不匹配（這個例子是「Code」反彙編和編譯器生成的代碼不匹配）。
-然後你須要找出爲什麼不匹配。通常很簡單-你看到代碼使用了空指針然後你看代碼想知道
-空指針是怎麼出現的，還有檢查它是否合法..
-
-現在，如果明白這是一項耗時的工作而且需要一丁點兒的專心，沒錯。這就是我爲什麼大多
-只是忽略那些沒有符號表信息的崩潰報告的原因：簡單的說太難查找了（我有一些
-程序用於在內核代碼段中搜索特定的模式，而且有時我也已經能找出那些崩潰的地方，但是
-僅僅是找出正確的序列也確實需要相當紮實的內核知識）
-
-_有時_會發生這種情況，我僅看到崩潰中的反彙編代碼序列， 然後我馬上就明白問題出在
-哪裡。這時我才意識到自己幹這個工作已經太長時間了;-)

----------------------------------------------------------------------------
-關於Oops跟蹤的註解：
-
-爲了幫助Linus和其它內核開發者，klogd納入了大量的支持來處理保護錯誤。爲了擁有對
-地址解析的完整支持至少應該使用1.3-pl3的sysklogd包。
-
-當保護錯誤發生時，klogd守護進程自動把內核日誌信息中的重要地址翻譯成它們相應的符
-號。
-
-klogd執行兩種類型的地址解析。首先是靜態翻譯其次是動態翻譯。靜態翻譯和ksymoops
-一樣使用System.map文件。爲了做靜態翻譯klogd守護進程必須在初始化時能找到system
-map文件。關於klogd怎樣搜索map文件請參看klogd手冊頁。
-
-動態地址翻譯在使用內核可裝載模塊時很重要。 因爲內核模塊的內存是從內核動態內存池
-里分配的，所以不管是模塊開始位置還是模塊中函數和符號的位置都不是固定的。
-
-內核支持允許程序決定裝載哪些模塊和它們在內存中位置的系統調用。使用這些系統調用
-klogd守護進程生成一張符號表用於調試發生在可裝載模塊中的保護錯誤。
-
-至少klogd會提供產生保護錯誤的模塊名。還可有額外的符號信息供可裝載模塊開發者選擇
-以從模塊中輸出符號信息。
-
-因爲內核模塊環境可能是動態的，所以必須有一種機制當模塊環境發生改變時來通知klogd
-守護進程。 有一些可用的命令行選項允許klogd向當前執行中的守護進程發送信號，告知符
-號信息應該被刷新了。 更多信息請參看klogd手冊頁。
-
-sysklogd發布時包含一個補丁修改了modules-2.0.0包，無論何時一個模塊裝載或者卸載都
-會自動向klogd發送信號。打上這個補丁提供了必要的對調試發生於內核可裝載模塊的保護
-錯誤的無縫支持。
-
-以下是被klogd處理過的發生在可裝載模塊中的一個保護錯誤例子：

-受汙染的內核
-
-一些oops報告在程序記數器之後包含字符串'Tainted: '。這表明內核已經被一些東西給汙
-染了。 該字符串之後緊跟著一系列的位置敏感的字符，每個代表一個特定的汙染值。
-
- 1：'G'如果所有裝載的模塊都有GPL或相容的許可證，'P'如果裝載了任何的專有模塊。
-沒有模塊MODULE_LICENSE或者帶有insmod認爲是與GPL不相容的的MODULE_LICENSE的模塊被
-認定是專有的。
-
- 2：'F'如果有任何通過「insmod -f」被強制裝載的模塊，' '如果所有模塊都被正常裝載。
-
- 3：'S'如果oops發生在SMP內核中，運行於沒有證明安全運行多處理器的硬體。 當前這種
-情況僅限於幾種不支持SMP的速龍處理器。
-
- 4：'R'如果模塊通過「insmod -f」被強制裝載，' '如果所有模塊都被正常裝載。
-
- 5：'M'如果任何處理器報告了機器檢查異常，' '如果沒有發生機器檢查異常。
-
- 6：'B'如果頁釋放函數發現了一個錯誤的頁引用或者一些非預期的頁標誌。
-
- 7：'U'如果用戶或者用戶應用程式特別請求設置汙染標誌，否則' '。
-
- 8：'D'如果內核剛剛死掉，比如有OOPS或者BUG。
-
-使用'Tainted: '字符串的主要原因是要告訴內核調試者，這是否是一個乾淨的內核亦或發
-生了任何的不正常的事。汙染是永久的：即使出錯的模塊已經被卸載了，汙染值仍然存在，
-以表明內核不再值得信任。

+=======================
+Introduction to Netlink
+=======================
+
+Netlink is often described as an ioctl() replacement.
+It aims to replace fixed-format C structures as supplied
+to ioctl() with a format which allows an easy way to add
+or extended the arguments.
+
+To achieve this Netlink uses a minimal fixed-format metadata header
+followed by multiple attributes in the TLV (type, length, value) format.
+
+Unfortunately the protocol has evolved over the years, in an organic
+and undocumented fashion, making it hard to coherently explain.
+To make the most practical sense this document starts by describing
+netlink as it is used today and dives into more "historical" uses
+in later sections.
+
+Opening a socket
+================
+
+Netlink communication happens over sockets, a socket needs to be
+opened first:
+
+.. code-block:: c
+
+ fd = socket(AF_NETLINK, SOCK_RAW, NETLINK_GENERIC);
+
+The use of sockets allows for a natural way of exchanging information
+in both directions (to and from the kernel). The operations are still
+performed synchronously when applications send() the request but
+a separate recv() system call is needed to read the reply.
+
+A very simplified flow of a Netlink "call" will therefore look
+something like:
+
+.. code-block:: c
+
+ fd = socket(AF_NETLINK, SOCK_RAW, NETLINK_GENERIC);
+
+ /* format the request */
+ send(fd, &request, sizeof(request));
+ n = recv(fd, &response, RSP_BUFFER_SIZE);
+ /* interpret the response */
+
+Netlink also provides natural support for "dumping", i.e. communicating
+to user space all objects of a certain type (e.g. dumping all network
+interfaces).
+
+.. code-block:: c
+
+ fd = socket(AF_NETLINK, SOCK_RAW, NETLINK_GENERIC);
+
+ /* format the dump request */
+ send(fd, &request, sizeof(request));
+ while (1) {
+ n = recv(fd, &buffer, RSP_BUFFER_SIZE);
+ /* one recv() call can read multiple messages, hence the loop below */
+ for (nl_msg in buffer) {
+ if (nl_msg.nlmsg_type == NLMSG_DONE)
+ goto dump_finished;
+ /* process the object */
+ }
+ }
+ dump_finished:
+
+The first two arguments of the socket() call require little explanation -
+it is opening a Netlink socket, with all headers provided by the user
+(hence NETLINK, RAW). The last argument is the protocol within Netlink.
+This field used to identify the subsystem with which the socket will
+communicate.
+
+Classic vs Generic Netlink
+--------------------------
+
+Initial implementation of Netlink depended on a static allocation
+of IDs to subsystems and provided little supporting infrastructure.
+Let us refer to those protocols collectively as **Classic Netlink**.
+The list of them is defined on top of the ``include/uapi/linux/netlink.h``
+file, they include among others - general networking (NETLINK_ROUTE),
+iSCSI (NETLINK_ISCSI), and audit (NETLINK_AUDIT).
+
+**Generic Netlink** (introduced in 2005) allows for dynamic registration of
+subsystems (and subsystem ID allocation), introspection and simplifies
+implementing the kernel side of the interface.
+
+The following section describes how to use Generic Netlink, as the
+number of subsystems using Generic Netlink outnumbers the older
+protocols by an order of magnitude. There are also no plans for adding
+more Classic Netlink protocols to the kernel.
+Basic information on how communicating with core networking parts of
+the Linux kernel (or another of the 20 subsystems using Classic
+Netlink) differs from Generic Netlink is provided later in this document.
+
+Generic Netlink
+===============
+
+In addition to the Netlink fixed metadata header each Netlink protocol
+defines its own fixed metadata header. (Similarly to how network
+headers stack - Ethernet > IP > TCP we have Netlink > Generic N. > Family.)
+
+A Netlink message always starts with struct nlmsghdr, which is followed
+by a protocol-specific header. In case of Generic Netlink the protocol
+header is struct genlmsghdr.
+
+The practical meaning of the fields in case of Generic Netlink is as follows:
+
+.. code-block:: c
+
+ struct nlmsghdr {
+ __u32 nlmsg_len; /* Length of message including headers */
+ __u16 nlmsg_type; /* Generic Netlink Family (subsystem) ID */
+ __u16 nlmsg_flags; /* Flags - request or dump */
+ __u32 nlmsg_seq; /* Sequence number */
+ __u32 nlmsg_pid; /* Port ID, set to 0 */
+ };
+ struct genlmsghdr {
+ __u8 cmd; /* Command, as defined by the Family */
+ __u8 version; /* Irrelevant, set to 1 */
+ __u16 reserved; /* Reserved, set to 0 */
+ };
+ /* TLV attributes follow... */
+
+In Classic Netlink :c:member:`nlmsghdr.nlmsg_type` used to identify
+which operation within the subsystem the message was referring to
+(e.g. get information about a netdev). Generic Netlink needs to mux
+multiple subsystems in a single protocol so it uses this field to
+identify the subsystem, and :c:member:`genlmsghdr.cmd` identifies
+the operation instead. (See :ref:`res_fam` for
+information on how to find the Family ID of the subsystem of interest.)
+Note that the first 16 values (0 - 15) of this field are reserved for
+control messages both in Classic Netlink and Generic Netlink.
+See :ref:`nl_msg_type` for more details.
+
+There are 3 usual types of message exchanges on a Netlink socket:
+
+ - performing a single action (``do``);
+ - dumping information (``dump``);
+ - getting asynchronous notifications (``multicast``).
+
+Classic Netlink is very flexible and presumably allows other types
+of exchanges to happen, but in practice those are the three that get
+used.
+
+Asynchronous notifications are sent by the kernel and received by
+the user sockets which subscribed to them. ``do`` and ``dump`` requests
+are initiated by the user. :c:member:`nlmsghdr.nlmsg_flags` should
+be set as follows:
+
+ - for ``do``: ``NLM_F_REQUEST | NLM_F_ACK``
+ - for ``dump``: ``NLM_F_REQUEST | NLM_F_ACK | NLM_F_DUMP``
+
+:c:member:`nlmsghdr.nlmsg_seq` should be a set to a monotonically
+increasing value. The value gets echoed back in responses and doesn't
+matter in practice, but setting it to an increasing value for each
+message sent is considered good hygiene. The purpose of the field is
+matching responses to requests. Asynchronous notifications will have
+:c:member:`nlmsghdr.nlmsg_seq` of ``0``.
+
+:c:member:`nlmsghdr.nlmsg_pid` is the Netlink equivalent of an address.
+This field can be set to ``0`` when talking to the kernel.
+See :ref:`nlmsg_pid` for the (uncommon) uses of the field.
+
+The expected use for :c:member:`genlmsghdr.version` was to allow
+versioning of the APIs provided by the subsystems. No subsystem to
+date made significant use of this field, so setting it to ``1`` seems
+like a safe bet.
+
+.. _nl_msg_type:
+
+Netlink message types
+---------------------
+
+As previously mentioned :c:member:`nlmsghdr.nlmsg_type` carries
+protocol specific values but the first 16 identifiers are reserved
+(first subsystem specific message type should be equal to
+``NLMSG_MIN_TYPE`` which is ``0x10``).
+
+There are only 4 Netlink control messages defined:
+
+ - ``NLMSG_NOOP`` - ignore the message, not used in practice;
+ - ``NLMSG_ERROR`` - carries the return code of an operation;
+ - ``NLMSG_DONE`` - marks the end of a dump;
+ - ``NLMSG_OVERRUN`` - socket buffer has overflown, not used to date.
+
+``NLMSG_ERROR`` and ``NLMSG_DONE`` are of practical importance.
+They carry return codes for operations. Note that unless
+the ``NLM_F_ACK`` flag is set on the request Netlink will not respond
+with ``NLMSG_ERROR`` if there is no error. To avoid having to special-case
+this quirk it is recommended to always set ``NLM_F_ACK``.
+
+The format of ``NLMSG_ERROR`` is described by struct nlmsgerr::
+
+ ----------------------------------------------
+ | struct nlmsghdr - response header |
+ ----------------------------------------------
+ | int error |
+ ----------------------------------------------
+ | struct nlmsghdr - original request header |
+ ----------------------------------------------
+ | ** optionally (1) payload of the request |
+ ----------------------------------------------
+ | ** optionally (2) extended ACK |
+ ----------------------------------------------
+
+There are two instances of struct nlmsghdr here, first of the response
+and second of the request. ``NLMSG_ERROR`` carries the information about
+the request which led to the error. This could be useful when trying
+to match requests to responses or re-parse the request to dump it into
+logs.
+
+The payload of the request is not echoed in messages reporting success
+(``error == 0``) or if ``NETLINK_CAP_ACK`` setsockopt() was set.
+The latter is common
+and perhaps recommended as having to read a copy of every request back
+from the kernel is rather wasteful. The absence of request payload
+is indicated by ``NLM_F_CAPPED`` in :c:member:`nlmsghdr.nlmsg_flags`.
+
+The second optional element of ``NLMSG_ERROR`` are the extended ACK
+attributes. See :ref:`ext_ack` for more details. The presence
+of extended ACK is indicated by ``NLM_F_ACK_TLVS`` in
+:c:member:`nlmsghdr.nlmsg_flags`.
+
+``NLMSG_DONE`` is simpler, the request is never echoed but the extended
+ACK attributes may be present::
+
+ ----------------------------------------------
+ | struct nlmsghdr - response header |
+ ----------------------------------------------
+ | int error |
+ ----------------------------------------------
+ | ** optionally extended ACK |
+ ----------------------------------------------
+
+.. _res_fam:
+
+Resolving the Family ID
+-----------------------
+
+This section explains how to find the Family ID of a subsystem.
+It also serves as an example of Generic Netlink communication.
+
+Generic Netlink is itself a subsystem exposed via the Generic Netlink API.
+To avoid a circular dependency Generic Netlink has a statically allocated
+Family ID (``GENL_ID_CTRL`` which is equal to ``NLMSG_MIN_TYPE``).
+The Generic Netlink family implements a command used to find out information
+about other families (``CTRL_CMD_GETFAMILY``).
+
+To get information about the Generic Netlink family named for example
+``"test1"`` we need to send a message on the previously opened Generic Netlink
+socket. The message should target the Generic Netlink Family (1), be a
+``do`` (2) call to ``CTRL_CMD_GETFAMILY`` (3). A ``dump`` version of this
+call would make the kernel respond with information about *all* the families
+it knows about. Last but not least the name of the family in question has
+to be specified (4) as an attribute with the appropriate type::
+
+ struct nlmsghdr:
+ __u32 nlmsg_len: 32
+ __u16 nlmsg_type: GENL_ID_CTRL // (1)
+ __u16 nlmsg_flags: NLM_F_REQUEST | NLM_F_ACK // (2)
+ __u32 nlmsg_seq: 1
+ __u32 nlmsg_pid: 0
+
+ struct genlmsghdr:
+ __u8 cmd: CTRL_CMD_GETFAMILY // (3)
+ __u8 version: 2 /* or 1, doesn't matter */
+ __u16 reserved: 0
+
+ struct nlattr: // (4)
+ __u16 nla_len: 10
+ __u16 nla_type: CTRL_ATTR_FAMILY_NAME
+ char data: test1\0
+
+ (padding:)
+ char data: \0\0
+
+The length fields in Netlink (:c:member:`nlmsghdr.nlmsg_len`
+and :c:member:`nlattr.nla_len`) always *include* the header.
+Attribute headers in netlink must be aligned to 4 bytes from the start
+of the message, hence the extra ``\0\0`` after ``CTRL_ATTR_FAMILY_NAME``.
+The attribute lengths *exclude* the padding.
+
+If the family is found kernel will reply with two messages, the response
+with all the information about the family::
+
+ /* Message #1 - reply */
+ struct nlmsghdr:
+ __u32 nlmsg_len: 136
+ __u16 nlmsg_type: GENL_ID_CTRL
+ __u16 nlmsg_flags: 0
+ __u32 nlmsg_seq: 1 /* echoed from our request */
+ __u32 nlmsg_pid: 5831 /* The PID of our user space process */
+
+ struct genlmsghdr:
+ __u8 cmd: CTRL_CMD_GETFAMILY
+ __u8 version: 2
+ __u16 reserved: 0
+
+ struct nlattr:
+ __u16 nla_len: 10
+ __u16 nla_type: CTRL_ATTR_FAMILY_NAME
+ char data: test1\0
+
+ (padding:)
+ data: \0\0
+
+ struct nlattr:
+ __u16 nla_len: 6
+ __u16 nla_type: CTRL_ATTR_FAMILY_ID
+ __u16: 123 /* The Family ID we are after */
+
+ (padding:)
+ char data: \0\0
+
+ struct nlattr:
+ __u16 nla_len: 9
+ __u16 nla_type: CTRL_ATTR_FAMILY_VERSION
+ __u16: 1
+
+ /* ... etc, more attributes will follow. */
+
+And the error code (success) since ``NLM_F_ACK`` had been set on the request::
+
+ /* Message #2 - the ACK */
+ struct nlmsghdr:
+ __u32 nlmsg_len: 36
+ __u16 nlmsg_type: NLMSG_ERROR
+ __u16 nlmsg_flags: NLM_F_CAPPED /* There won't be a payload */
+ __u32 nlmsg_seq: 1 /* echoed from our request */
+ __u32 nlmsg_pid: 5831 /* The PID of our user space process */
+
+ int error: 0
+
+ struct nlmsghdr: /* Copy of the request header as we sent it */
+ __u32 nlmsg_len: 32
+ __u16 nlmsg_type: GENL_ID_CTRL
+ __u16 nlmsg_flags: NLM_F_REQUEST | NLM_F_ACK
+ __u32 nlmsg_seq: 1
+ __u32 nlmsg_pid: 0
+
+The order of attributes (struct nlattr) is not guaranteed so the user
+has to walk the attributes and parse them.
+
+Note that Generic Netlink sockets are not associated or bound to a single
+family. A socket can be used to exchange messages with many different
+families, selecting the recipient family on message-by-message basis using
+the :c:member:`nlmsghdr.nlmsg_type` field.
+
+.. _ext_ack:
+
+Extended ACK
+------------
+
+Extended ACK controls reporting of additional error/warning TLVs
+in ``NLMSG_ERROR`` and ``NLMSG_DONE`` messages. To maintain backward
+compatibility this feature has to be explicitly enabled by setting
+the ``NETLINK_EXT_ACK`` setsockopt() to ``1``.
+
+Types of extended ack attributes are defined in enum nlmsgerr_attrs.
+The most commonly used attributes are ``NLMSGERR_ATTR_MSG``,
+``NLMSGERR_ATTR_OFFS`` and ``NLMSGERR_ATTR_MISS_*``.
+
+``NLMSGERR_ATTR_MSG`` carries a message in English describing
+the encountered problem. These messages are far more detailed
+than what can be expressed thru standard UNIX error codes.
+
+``NLMSGERR_ATTR_OFFS`` points to the attribute which caused the problem.
+
+``NLMSGERR_ATTR_MISS_TYPE`` and ``NLMSGERR_ATTR_MISS_NEST``
+inform about a missing attribute.
+
+Extended ACKs can be reported on errors as well as in case of success.
+The latter should be treated as a warning.
+
+Extended ACKs greatly improve the usability of Netlink and should
+always be enabled, appropriately parsed and reported to the user.
+
+Advanced topics
+===============
+
+Dump consistency
+----------------
+
+Some of the data structures kernel uses for storing objects make
+it hard to provide an atomic snapshot of all the objects in a dump
+(without impacting the fast-paths updating them).
+
+Kernel may set the ``NLM_F_DUMP_INTR`` flag on any message in a dump
+(including the ``NLMSG_DONE`` message) if the dump was interrupted and
+may be inconsistent (e.g. missing objects). User space should retry
+the dump if it sees the flag set.
+
+Introspection
+-------------
+
+The basic introspection abilities are enabled by access to the Family
+object as reported in :ref:`res_fam`. User can query information about
+the Generic Netlink family, including which operations are supported
+by the kernel and what attributes the kernel understands.
+Family information includes the highest ID of an attribute kernel can parse,
+a separate command (``CTRL_CMD_GETPOLICY``) provides detailed information
+about supported attributes, including ranges of values the kernel accepts.
+
+Querying family information is useful in cases when user space needs
+to make sure that the kernel has support for a feature before issuing
+a request.
+
+.. _nlmsg_pid:
+
+nlmsg_pid
+---------
+
+:c:member:`nlmsghdr.nlmsg_pid` is the Netlink equivalent of an address.
+It is referred to as Port ID, sometimes Process ID because for historical
+reasons if the application does not select (bind() to) an explicit Port ID
+kernel will automatically assign it the ID equal to its Process ID
+(as reported by the getpid() system call).
+
+Similarly to the bind() semantics of the TCP/IP network protocols the value
+of zero means "assign automatically", hence it is common for applications
+to leave the :c:member:`nlmsghdr.nlmsg_pid` field initialized to ``0``.
+
+The field is still used today in rare cases when kernel needs to send
+a unicast notification. User space application can use bind() to associate
+its socket with a specific PID, it then communicates its PID to the kernel.
+This way the kernel can reach the specific user space process.
+
+This sort of communication is utilized in UMH (User Mode Helper)-like
+scenarios when kernel needs to trigger user space processing or ask user
+space for a policy decision.
+
+Multicast notifications
+-----------------------
+
+One of the strengths of Netlink is the ability to send event notifications
+to user space. This is a unidirectional form of communication (kernel ->
+user) and does not involve any control messages like ``NLMSG_ERROR`` or
+``NLMSG_DONE``.
+
+For example the Generic Netlink family itself defines a set of multicast
+notifications about registered families. When a new family is added the
+sockets subscribed to the notifications will get the following message::
+
+ struct nlmsghdr:
+ __u32 nlmsg_len: 136
+ __u16 nlmsg_type: GENL_ID_CTRL
+ __u16 nlmsg_flags: 0
+ __u32 nlmsg_seq: 0
+ __u32 nlmsg_pid: 0
+
+ struct genlmsghdr:
+ __u8 cmd: CTRL_CMD_NEWFAMILY
+ __u8 version: 2
+ __u16 reserved: 0
+
+ struct nlattr:
+ __u16 nla_len: 10
+ __u16 nla_type: CTRL_ATTR_FAMILY_NAME
+ char data: test1\0
+
+ (padding:)
+ data: \0\0
+
+ struct nlattr:
+ __u16 nla_len: 6
+ __u16 nla_type: CTRL_ATTR_FAMILY_ID
+ __u16: 123 /* The Family ID we are after */
+
+ (padding:)
+ char data: \0\0
+
+ struct nlattr:
+ __u16 nla_len: 9
+ __u16 nla_type: CTRL_ATTR_FAMILY_VERSION
+ __u16: 1
+
+ /* ... etc, more attributes will follow. */
+
+The notification contains the same information as the response
+to the ``CTRL_CMD_GETFAMILY`` request.
+
+The Netlink headers of the notification are mostly 0 and irrelevant.
+The :c:member:`nlmsghdr.nlmsg_seq` may be either zero or a monotonically
+increasing notification sequence number maintained by the family.
+
+To receive notifications the user socket must subscribe to the relevant
+notification group. Much like the Family ID, the Group ID for a given
+multicast group is dynamic and can be found inside the Family information.
+The ``CTRL_ATTR_MCAST_GROUPS`` attribute contains nests with names
+(``CTRL_ATTR_MCAST_GRP_NAME``) and IDs (``CTRL_ATTR_MCAST_GRP_ID``) of
+the groups family.
+
+Once the Group ID is known a setsockopt() call adds the socket to the group:
+
+.. code-block:: c
+
+ unsigned int group_id;
+
+ /* .. find the group ID... */
+
+ setsockopt(fd, SOL_NETLINK, NETLINK_ADD_MEMBERSHIP,
+ &group_id, sizeof(group_id));
+
+The socket will now receive notifications.
+
+It is recommended to use separate sockets for receiving notifications
+and sending requests to the kernel. The asynchronous nature of notifications
+means that they may get mixed in with the responses making the message
+handling much harder.
+
+Buffer sizing
+-------------
+
+Netlink sockets are datagram sockets rather than stream sockets,
+meaning that each message must be received in its entirety by a single
+recv()/recvmsg() system call. If the buffer provided by the user is too
+short, the message will be truncated and the ``MSG_TRUNC`` flag set
+in struct msghdr (struct msghdr is the second argument
+of the recvmsg() system call, *not* a Netlink header).
+
+Upon truncation the remaining part of the message is discarded.
+
+Netlink expects that the user buffer will be at least 8kB or a page
+size of the CPU architecture, whichever is bigger. Particular Netlink
+families may, however, require a larger buffer. 32kB buffer is recommended
+for most efficient handling of dumps (larger buffer fits more dumped
+objects and therefore fewer recvmsg() calls are needed).
+
+Classic Netlink
+===============
+
+The main differences between Classic and Generic Netlink are the dynamic
+allocation of subsystem identifiers and availability of introspection.
+In theory the protocol does not differ significantly, however, in practice
+Classic Netlink experimented with concepts which were abandoned in Generic
+Netlink (really, they usually only found use in a small corner of a single
+subsystem). This section is meant as an explainer of a few of such concepts,
+with the explicit goal of giving the Generic Netlink
+users the confidence to ignore them when reading the uAPI headers.
+
+Most of the concepts and examples here refer to the ``NETLINK_ROUTE`` family,
+which covers much of the configuration of the Linux networking stack.
+Real documentation of that family, deserves a chapter (or a book) of its own.
+
+Families
+--------
+
+Netlink refers to subsystems as families. This is a remnant of using
+sockets and the concept of protocol families, which are part of message
+demultiplexing in ``NETLINK_ROUTE``.
+
+Sadly every layer of encapsulation likes to refer to whatever it's carrying
+as "families" making the term very confusing:
+
+ 1. AF_NETLINK is a bona fide socket protocol family
+ 2. AF_NETLINK's documentation refers to what comes after its own
+ header (struct nlmsghdr) in a message as a "Family Header"
+ 3. Generic Netlink is a family for AF_NETLINK (struct genlmsghdr follows
+ struct nlmsghdr), yet it also calls its users "Families".
+
+Note that the Generic Netlink Family IDs are in a different "ID space"
+and overlap with Classic Netlink protocol numbers (e.g. ``NETLINK_CRYPTO``
+has the Classic Netlink protocol ID of 21 which Generic Netlink will
+happily allocate to one of its families as well).
+
+Strict checking
+---------------
+
+The ``NETLINK_GET_STRICT_CHK`` socket option enables strict input checking
+in ``NETLINK_ROUTE``. It was needed because historically kernel did not
+validate the fields of structures it didn't process. This made it impossible
+to start using those fields later without risking regressions in applications
+which initialized them incorrectly or not at all.
+
+``NETLINK_GET_STRICT_CHK`` declares that the application is initializing
+all fields correctly. It also opts into validating that message does not
+contain trailing data and requests that kernel rejects attributes with
+type higher than largest attribute type known to the kernel.
+
+``NETLINK_GET_STRICT_CHK`` is not used outside of ``NETLINK_ROUTE``.
+
+Unknown attributes
+------------------
+
+Historically Netlink ignored all unknown attributes. The thinking was that
+it would free the application from having to probe what kernel supports.
+The application could make a request to change the state and check which
+parts of the request "stuck".
+
+This is no longer the case for new Generic Netlink families and those opting
+in to strict checking. See enum netlink_validation for validation types
+performed.
+
+Fixed metadata and structures
+-----------------------------
+
+Classic Netlink made liberal use of fixed-format structures within
+the messages. Messages would commonly have a structure with
+a considerable number of fields after struct nlmsghdr. It was also
+common to put structures with multiple members inside attributes,
+without breaking each member into an attribute of its own.
+
+This has caused problems with validation and extensibility and
+therefore using binary structures is actively discouraged for new
+attributes.
+
+Request types
+-------------
+
+``NETLINK_ROUTE`` categorized requests into 4 types ``NEW``, ``DEL``, ``GET``,
+and ``SET``. Each object can handle all or some of those requests
+(objects being netdevs, routes, addresses, qdiscs etc.) Request type
+is defined by the 2 lowest bits of the message type, so commands for
+new objects would always be allocated with a stride of 4.
+
+Each object would also have it's own fixed metadata shared by all request
+types (e.g. struct ifinfomsg for netdev requests, struct ifaddrmsg for address
+requests, struct tcmsg for qdisc requests).
+
+Even though other protocols and Generic Netlink commands often use
+the same verbs in their message names (``GET``, ``SET``) the concept
+of request types did not find wider adoption.
+
+Notification echo
+-----------------
+
+``NLM_F_ECHO`` requests for notifications resulting from the request
+to be queued onto the requesting socket. This is useful to discover
+the impact of the request.
+
+Note that this feature is not universally implemented.
+
+Other request-type-specific flags
+---------------------------------
+
+Classic Netlink defined various flags for its ``GET``, ``NEW``
+and ``DEL`` requests in the upper byte of nlmsg_flags in struct nlmsghdr.
+Since request types have not been generalized the request type specific
+flags are rarely used (and considered deprecated for new families).
+
+For ``GET`` - ``NLM_F_ROOT`` and ``NLM_F_MATCH`` are combined into
+``NLM_F_DUMP``, and not used separately. ``NLM_F_ATOMIC`` is never used.
+
+For ``DEL`` - ``NLM_F_NONREC`` is only used by nftables and ``NLM_F_BULK``
+only by FDB some operations.
+
+The flags for ``NEW`` are used most commonly in classic Netlink. Unfortunately,
+the meaning is not crystal clear. The following description is based on the
+best guess of the intention of the authors, and in practice all families
+stray from it in one way or another. ``NLM_F_REPLACE`` asks to replace
+an existing object, if no matching object exists the operation should fail.
+``NLM_F_EXCL`` has the opposite semantics and only succeeds if object already
+existed.
+``NLM_F_CREATE`` asks for the object to be created if it does not
+exist, it can be combined with ``NLM_F_REPLACE`` and ``NLM_F_EXCL``.
+
+A comment in the main Netlink uAPI header states::
+
+ 4.4BSD ADD NLM_F_CREATE|NLM_F_EXCL
+ 4.4BSD CHANGE NLM_F_REPLACE
+
+ True CHANGE NLM_F_CREATE|NLM_F_REPLACE
+ Append NLM_F_CREATE
+ Check NLM_F_EXCL
+
+which seems to indicate that those flags predate request types.

/lib/firmware/{intel-ucode,amd-ucode}. The default distro installation
packages already put them there.
+Since kernel 5.19, late loading is not enabled by default.
+
+The /dev/cpu/microcode method has been removed in 5.19.
+
+Why is late loading dangerous?
+==============================
+
+Synchronizing all CPUs
+----------------------
+
+The microcode engine which receives the microcode update is shared
+between the two logical threads in a SMT system. Therefore, when
+the update is executed on one SMT thread of the core, the sibling
+"automatically" gets the update.
+
+Since the microcode can "simulate" MSRs too, while the microcode update
+is in progress, those simulated MSRs transiently cease to exist. This
+can result in unpredictable results if the SMT sibling thread happens to
+be in the middle of an access to such an MSR. The usual observation is
+that such MSR accesses cause #GPs to be raised to signal that former are
+not present.
+
+The disappearing MSRs are just one common issue which is being observed.
+Any other instruction that's being patched and gets concurrently
+executed by the other SMT sibling, can also result in similar,
+unpredictable behavior.
+
+To eliminate this case, a stop_machine()-based CPU synchronization was
+introduced as a way to guarantee that all logical CPUs will not execute
+any code but just wait in a spin loop, polling an atomic variable.
+
+While this took care of device or external interrupts, IPIs including
+LVT ones, such as CMCI etc, it cannot address other special interrupts
+that can't be shut off. Those are Machine Check (#MC), System Management
+(#SMI) and Non-Maskable interrupts (#NMI).
+
+Machine Checks
+--------------
+
+Machine Checks (#MC) are non-maskable. There are two kinds of MCEs.
+Fatal un-recoverable MCEs and recoverable MCEs. While un-recoverable
+errors are fatal, recoverable errors can also happen in kernel context
+are also treated as fatal by the kernel.
+
+On certain Intel machines, MCEs are also broadcast to all threads in a
+system. If one thread is in the middle of executing WRMSR, a MCE will be
+taken at the end of the flow. Either way, they will wait for the thread
+performing the wrmsr(0x79) to rendezvous in the MCE handler and shutdown
+eventually if any of the threads in the system fail to check in to the
+MCE rendezvous.
+
+To be paranoid and get predictable behavior, the OS can choose to set
+MCG_STATUS.MCIP. Since MCEs can be at most one in a system, if an
+MCE was signaled, the above condition will promote to a system reset
+automatically. OS can turn off MCIP at the end of the update for that
+core.
+
+System Management Interrupt
+---------------------------
+
+SMIs are also broadcast to all CPUs in the platform. Microcode update
+requests exclusive access to the core before writing to MSR 0x79. So if
+it does happen such that, one thread is in WRMSR flow, and the 2nd got
+an SMI, that thread will be stopped in the first instruction in the SMI
+handler.
+
+Since the secondary thread is stopped in the first instruction in SMI,
+there is very little chance that it would be in the middle of executing
+an instruction being patched. Plus OS has no way to stop SMIs from
+happening.
+
+Non-Maskable Interrupts
+-----------------------
+
+When thread0 of a core is doing the microcode update, if thread1 is
+pulled into NMI, that can cause unpredictable behavior due to the
+reasons above.
+
+OS can choose a variety of methods to avoid running into this situation.
+
+
+Is the microcode suitable for late loading?
+-------------------------------------------
+
+Late loading is done when the system is fully operational and running
+real workloads. Late loading behavior depends on what the base patch on
+the CPU is before upgrading to the new patch.
+
+This is true for Intel CPUs.
+
+Consider, for example, a CPU has patch level 1 and the update is to
+patch level 3.
+
+Between patch1 and patch3, patch2 might have deprecated a software-visible
+feature.
+
+This is unacceptable if software is even potentially using that feature.
+For instance, say MSR_X is no longer available after an update,
+accessing that MSR will cause a #GP fault.
+
+Basically there is no way to declare a new microcode update suitable
+for late-loading. This is another one of the problems that caused late
+loading to be not enabled by default.

+ Ocelot is a family of networking chips that support multiple ethernet

+ * These steps are required in order to ensure that we do not accidentally

+ * do not directly update the cached timestamp here because it is possible
+ * this might produce an error when ICE_CFG_BUSY is set. If this occurred, we
+ * would have to try again. During that time window, timestamps might be
+ * requested and returned with an invalid extension. Thus, on failure to
+ * immediately update the cached PHC time we would need to zero the value
+ * anyways. For this reason, we just zero the value immediately and queue the

- *
- * Process timestamps captured by the PHY associated with this port. To do

- *
- * If a given index has a valid timestamp, perform the following steps:
- *
- * 1) copy the timestamp out of the PHY register
- * 4) clear the timestamp valid bit in the PHY register
- * 5) unlock the index by clearing the associated in_use bit.
- * 2) extend the 40b timestamp value to get a 64bit timestamp
- * 3) send that timestamp to the stack
- *
- * After looping, if we still have waiting SKBs, then re-queue the work. This
- * may cause us effectively poll even when not strictly necessary. We do this
- * because it's possible a new timestamp was requested around the same time as
- * the interrupt. In some cases hardware might not interrupt us again when the
- * timestamp is captured.
- *
- * Note that we only take the tracking lock when clearing the bit and when
- * checking if we need to re-queue this task. The only place where bits can be
- * set is the hard xmit routine where an SKB has a request flag set. The only
- * places where we clear bits are this work function, or the periodic cleanup
- * thread. If the cleanup thread clears a bit we're processing we catch it
- * when we lock to clear the bit and then grab the SKB pointer. If a Tx thread
- * starts a new timestamp, we might not begin processing it right away but we
- * will notice it at the end when we re-queue the work item. If a Tx thread
- * starts a new timestamp just after this function exits without re-queuing,
- * the interrupt when the timestamp finishes should trigger. Avoiding holding
- * the lock for the entire function is important in order to ensure that Tx
- * threads do not get blocked while waiting for the lock.

* DOC: GSI Transactions

* to be performed. When a transaction has completed a callback function

- * To perform a command (or set of them), a user of the GSI transaction
+ * To perform an operation (or set of them), a user of the GSI transaction
* interface allocates a transaction, indicating the number of TREs required
- * (one per command). If sufficient TREs are available, they are reserved
+ * (one per operation). If sufficient TREs are available, they are reserved
* for use in the transaction and the allocation succeeds. This way
- * exhaustion of the available TREs in a channel ring is detected
- * as early as possible. All resources required to complete a transaction
- * are allocated at transaction allocation time.
+ * exhaustion of the available TREs in a channel ring is detected as early
+ * as possible. Any other resources that might be needed to complete a
+ * transaction are also allocated when the transaction is allocated.
*
- * Commands performed as part of a transaction are represented in an array
- * of Linux scatterlist structures. This array is allocated with the
- * transaction, and its entries are initialized using standard scatterlist
- * functions (such as sg_set_buf() or skb_to_sgvec()).
+ * Operations performed as part of a transaction are represented in an array
+ * of Linux scatterlist structures, allocated with the transaction. These
+ * scatterlist structures are initialized by "adding" operations to the
+ * transaction. If a buffer in an operation must be mapped for DMA, this is
+ * done at the time it is added to the transaction. It is possible for a
+ * mapping error to occur when an operation is added. In this case the
+ * transaction should simply be freed; this correctly releases resources
+ * associated with the transaction.
*
- * Once a transaction's scatterlist structures have been initialized, the
- * transaction is committed. The caller is responsible for mapping buffers
- * for DMA if necessary, and this should be done *before* allocating
- * the transaction. Between a successful allocation and commit of a
- * transaction no errors should occur.
- *

* DOC: IPA Registers
*
* IPA registers are located within the "ipa-reg" address space defined by
- * Device Tree. The offset of each register within that space is specified
- * by symbols defined below. The address space is mapped to virtual memory
- * space in ipa_mem_init(). All IPA registers are 32 bits wide.
+ * Device Tree. Each register has a specified offset within that space,
+ * which is mapped into virtual memory space in ipa_mem_init(). Each
+ * has a unique identifer, taken from the ipa_reg_id enumerated type.
+ * All IPA registers are 32 bits wide.
*
- * Certain register types are duplicated for a number of instances of
- * something. For example, each IPA endpoint has an set of registers
- * defining its configuration. The offset to an endpoint's set of registers
- * is computed based on an "base" offset, plus an endpoint's ID multiplied
- * and a "stride" value for the register. For such registers, the offset is
- * computed by a function-like macro that takes a parameter used in the
- * computation.
+ * Certain "parameterized" register types are duplicated for a number of
+ * instances of something. For example, each IPA endpoint has an set of
+ * registers defining its configuration. The offset to an endpoint's set
+ * of registers is computed based on an "base" offset, plus an endpoint's
+ * ID multiplied and a "stride" value for the register. Similarly, some
+ * registers have an offset that depends on execution environment. In
+ * this case, the stride is multiplied by a member of the gsi_ee_id
+ * enumerated type.
*
- * Some register offsets depend on execution environment. For these an "ee"
- * parameter is supplied to the offset macro. The "ee" value is a member of
- * the gsi_ee enumerated type.
+ * Each version of IPA implements an array of ipa_reg structures indexed
+ * by register ID. Each entry in the array specifies the base offset and
+ * (for parameterized registers) a non-zero stride value. Not all versions
+ * of IPA define all registers. The offset for a register is returned by
+ * ipa_reg_offset() when the register's ipa_reg structure is supplied;
+ * zero is returned for an undefined register (this should never happen).
*
- * The offset of a register dependent on endpoint ID is computed by a macro
- * that is supplied a parameter "ep", "txep", or "rxep". A register with an
- * "ep" parameter is valid for any endpoint; a register with a "txep" or
- * "rxep" parameter is valid only for TX or RX endpoints, respectively. The
- * "*ep" value is assumed to be less than the maximum valid endpoint ID
- * for the current hardware, and that will not exceed IPA_ENDPOINT_MAX.
- *
- * The offset of registers related to filter and route tables is computed
- * by a macro that is supplied a parameter "er". The "er" represents an
- * endpoint ID for filters, or a route ID for routes. For filters, the
- * endpoint ID must be less than IPA_ENDPOINT_MAX, but is further restricted
- * because not all endpoints support filtering. For routes, the route ID
- * must be less than IPA_ROUTE_MAX.
- *
- * The offset of registers related to resource types is computed by a macro
- * that is supplied a parameter "rt". The "rt" represents a resource type,
- * which is a member of the ipa_resource_type_src enumerated type for
- * source endpoint resources or the ipa_resource_type_dst enumerated type
- * for destination endpoint resources.
- *
- * Some registers encode multiple fields within them. For these, each field
- * has a symbol below defining a field mask that encodes both the position
- * and width of the field within its register.
- *
- * In some cases, different versions of IPA hardware use different offset or
- * field mask values. In such cases an inline_function(ipa) is used rather
- * than a MACRO to define the offset or field mask to use.
- *
- * Finally, some registers hold bitmasks representing endpoints. In such
- * cases the @available field in the @ipa structure defines the "full" set
- * of valid bits for the register.
+ * Some registers encode multiple fields within them. Each field in
+ * such a register has a unique identifier (from an enumerated type).
+ * The position and width of the fields in a register are defined by
+ * an array of field masks, indexed by field ID. Two functions are
+ * used to access register fields; both take an ipa_reg structure as
+ * argument. To encode a value to be represented in a register field,
+ * the value and field ID are passed to ipa_reg_encode(). To extract
+ * a value encoded in a register field, the field ID is passed to
+ * ipa_reg_decode(). In addition, for single-bit fields, ipa_reg_bit()
+ * can be used to either encode the bit value, or to generate a mask
+ * used to extract the bit value.

- tristate "Kernel support for a.out and ECOFF binaries"
- depends on HAVE_AOUT
- help
- A.out (Assembler.OUTput) is a set of formats for libraries and
- executables used in the earliest versions of UNIX. Linux used
- the a.out formats QMAGIC and ZMAGIC until they were replaced
- with the ELF format.
-
- The conversion to ELF started in 1995. This option is primarily
- provided for historical interest and for the benefit of those
- who need to run binaries from that era.
-
- Most people should answer N here. If you think you may have
- occasional use for this format, enable module support above
- and answer M here to compile this support as a module called
- binfmt_aout.
-
- If any crucial components of your system (such as /sbin/init
- or /lib/ld.so) are still in a.out format, you will have to
- say Y here.
-

- help
- Say Y if you are using OSF/1 binaries (like Netscape and Acrobat)
- with v4 shared libraries freely available from Compaq. If you're
- going to use shared libraries from Tru64 version 5.0 or later, say N.

+ * mapped according to the relevant mount- and filesystem idmapping. It is
+ * important that the ACL_{GROUP,USER} entries in struct posix_acl will be
+ * mapped into k{g,u}id_t that are supposed to be mapped up in the filesystem
+ * idmapping. This is crucial since the resulting struct posix_acl might be
+ * cached filesystem wide. The vfs_set_acl_prepare() function will take care to
+ * perform all necessary idmappings.
+ *
+ * Note, that since basically forever the {g,u}id values encoded as
+ * ACL_{GROUP,USER} entries in the uapi POSIX ACLs passed via @value contain
+ * values that have been mapped according to the caller's idmapping. In other
+ * words, POSIX ACLs passed in uapi format as @value during setxattr() contain
+ * {g,u}id values in their ACL_{GROUP,USER} entries that should actually have
+ * been stored as k{g,u}id_t.
+ *
+ * This means, vfs_set_acl_prepare() needs to first recover the k{g,u}id_t by
+ * calling K{G,U}IDT_INIT(). Afterwards they can be interpreted as vfs{g,u}id_t
+ * through from_vfs{g,u}id() to account for any idmapped mounts. The
+ * vfs_set_acl_prepare_k{g,u}id() helpers will take care to generate the
+ * correct k{g,u}id_t.
+ *
+ * The filesystem will then receive the POSIX ACLs ready to be cached
+ * filesystem wide and ready to be written to the backing store taking the
+ * filesystem's idmapping into account.
+ *

+/* cgroup_iter provides four modes of traversal to the cgroup hierarchy.
+ *
+ * 1. Walk the descendants of a cgroup in pre-order.
+ * 2. Walk the descendants of a cgroup in post-order.
+ * 3. Walk the ancestors of a cgroup.
+ * 4. Show the given cgroup only.
+ *
+ * For walking descendants, cgroup_iter can walk in either pre-order or
+ * post-order. For walking ancestors, the iter walks up from a cgroup to
+ * the root.
+ *
+ * The iter program can terminate the walk early by returning 1. Walk
+ * continues if prog returns 0.
+ *
+ * The prog can check (seq->num == 0) to determine whether this is
+ * the first element. The prog may also be passed a NULL cgroup,
+ * which means the walk has completed and the prog has a chance to
+ * do post-processing, such as outputting an epilogue.
+ *
+ * Note: the iter_prog is called with cgroup_mutex held.
+ *
+ * Currently only one session is supported, which means, depending on the
+ * volume of data bpf program intends to send to user space, the number
+ * of cgroups that can be walked is limited. For example, given the current
+ * buffer size is 8 * PAGE_SIZE, if the program sends 64B data for each
+ * cgroup, assuming PAGE_SIZE is 4kb, the total number of cgroups that can
+ * be walked is 512. This is a limitation of cgroup_iter. If the output data
+ * is larger than the kernel buffer size, after all data in the kernel buffer
+ * is consumed by user space, the subsequent read() syscall will signal
+ * EOPNOTSUPP. In order to work around, the user may have to update their
+ * program to reduce the volume of data sent to output. For example, skip
+ * some uninteresting cgroups.

- The DECnet networking protocol was used in many products made by
- Digital (now Compaq). It provides reliable stream and sequenced
- packet communications over which run a variety of services similar
- to those which run over TCP/IP.
-
- To find some tools to use with the kernel layer support, please
- look at Patrick Caulfield's web site:
- <http://linux-decnet.sourceforge.net/>.
-
- More detailed documentation is available in
- <file:Documentation/networking/decnet.rst>.
-
- Be sure to say Y to "/proc file system support" and "Sysctl support"
- below when using DECnet, since you will need sysctl support to aid
- in configuration at run time.
-
- The DECnet code is also available as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want).
- The module is called decnet.
-
-config DECNET_ROUTER
- bool "DECnet: router support"
- depends on DECNET
- select FIB_RULES
- help
- Add support for turning your DECnet Endnode into a level 1 or 2
- router. This is an experimental, but functional option. If you
- do say Y here, then make sure that you also say Y to "Kernel/User
- network link driver", "Routing messages" and "Network packet
- filtering". The first two are required to allow configuration via
- rtnetlink (you will need Alexey Kuznetsov's iproute2 package
- from <ftp://ftp.tux.org/pub/net/ip-routing/>). The "Network packet
- filtering" option will be required for the forthcoming routing daemon
- to work.
-
- See <file:Documentation/networking/decnet.rst> for more information.

- * DECnet An implementation of the DECnet protocol suite for the LINUX
- * operating system. DECnet is implemented using the BSD Socket
- * interface as the means of communication with the user level.
- *
- * DECnet Socket Layer Interface
- *
- * Authors: Eduardo Marcelo Serrat <emserrat@geocities.com>
- * Patrick Caulfield <patrick@pandh.demon.co.uk>
- *
- * Changes:
- * Steve Whitehouse: Copied from Eduardo Serrat and Patrick Caulfield's
- * version of the code. Original copyright preserved
- * below.
- * Steve Whitehouse: Some bug fixes, cleaning up some code to make it
- * compatible with my routing layer.
- * Steve Whitehouse: Merging changes from Eduardo Serrat and Patrick
- * Caulfield.
- * Steve Whitehouse: Further bug fixes, checking module code still works
- * with new routing layer.
- * Steve Whitehouse: Additional set/get_sockopt() calls.
- * Steve Whitehouse: Fixed TIOCINQ ioctl to be same as Eduardo's new
- * code.
- * Steve Whitehouse: recvmsg() changed to try and behave in a POSIX like
- * way. Didn't manage it entirely, but its better.
- * Steve Whitehouse: ditto for sendmsg().
- * Steve Whitehouse: A selection of bug fixes to various things.
- * Steve Whitehouse: Added TIOCOUTQ ioctl.
- * Steve Whitehouse: Fixes to username2sockaddr & sockaddr2username.
- * Steve Whitehouse: Fixes to connect() error returns.
- * Patrick Caulfield: Fixes to delayed acceptance logic.
- * David S. Miller: New socket locking
- * Steve Whitehouse: Socket list hashing/locking
- * Arnaldo C. Melo: use capable, not suser
- * Steve Whitehouse: Removed unused code. Fix to use sk->allocation
- * when required.
- * Patrick Caulfield: /proc/net/decnet now has object name/number
- * Steve Whitehouse: Fixed local port allocation, hashed sk list
- * Matthew Wilcox: Fixes for dn_ioctl()
- * Steve Whitehouse: New connect/accept logic to allow timeouts and
- * prepare for sendpage etc.

- * DECnet An implementation of the DECnet protocol suite for the LINUX
- * operating system. DECnet is implemented using the BSD Socket
- * interface as the means of communication with the user level.
- *
- * DECnet Device Layer
- *
- * Authors: Steve Whitehouse <SteveW@ACM.org>
- * Eduardo Marcelo Serrat <emserrat@geocities.com>
- *
- * Changes:
- * Steve Whitehouse : Devices now see incoming frames so they
- * can mark on who it came from.
- * Steve Whitehouse : Fixed bug in creating neighbours. Each neighbour
- * can now have a device specific setup func.
- * Steve Whitehouse : Added /proc/sys/net/decnet/conf/<dev>/
- * Steve Whitehouse : Fixed bug which sometimes killed timer
- * Steve Whitehouse : Multiple ifaddr support
- * Steve Whitehouse : SIOCGIFCONF is now a compile time option
- * Steve Whitehouse : /proc/sys/net/decnet/conf/<sys>/forwarding
- * Steve Whitehouse : Removed timer1 - it's a user space issue now
- * Patrick Caulfield : Fixed router hello message format
- * Steve Whitehouse : Got rid of constant sizes for blksize for
- * devices. All mtu based now.

- * DECnet Neighbour Functions (Adjacency Database and

- *
- * Author: Steve Whitehouse <SteveW@ACM.org>
- *
- *
- * Changes:
- * Steve Whitehouse : Fixed router listing routine
- * Steve Whitehouse : Added error_report functions
- * Steve Whitehouse : Added default router detection
- * Steve Whitehouse : Hop counts in outgoing messages
- * Steve Whitehouse : Fixed src/dst in outgoing messages so
- * forwarding now stands a good chance of
- * working.
- * Steve Whitehouse : Fixed neighbour states (for now anyway).
- * Steve Whitehouse : Made error_report functions dummies. This
- * is not the right place to return skbs.
- * Steve Whitehouse : Convert to seq_file

- * DECnet An implementation of the DECnet protocol suite for the LINUX
- * operating system. DECnet is implemented using the BSD Socket
- * interface as the means of communication with the user level.
- *
- * DECnet Network Services Protocol (Input)
- *
- * Author: Eduardo Marcelo Serrat <emserrat@geocities.com>
- *
- * Changes:
- *
- * Steve Whitehouse: Split into dn_nsp_in.c and dn_nsp_out.c from
- * original dn_nsp.c.
- * Steve Whitehouse: Updated to work with my new routing architecture.
- * Steve Whitehouse: Add changes from Eduardo Serrat's patches.
- * Steve Whitehouse: Put all ack handling code in a common routine.
- * Steve Whitehouse: Put other common bits into dn_nsp_rx()
- * Steve Whitehouse: More checks on skb->len to catch bogus packets
- * Fixed various race conditions and possible nasties.
- * Steve Whitehouse: Now handles returned conninit frames.
- * David S. Miller: New socket locking
- * Steve Whitehouse: Fixed lockup when socket filtering was enabled.
- * Paul Koning: Fix to push CC sockets into RUN when acks are
- * received.
- * Steve Whitehouse:
- * Patrick Caulfield: Checking conninits for correctness & sending of error
- * responses.
- * Steve Whitehouse: Added backlog congestion level return codes.
- * Patrick Caulfield:
- * Steve Whitehouse: Added flow control support (outbound)
- * Steve Whitehouse: Prepare for nonlinear skbs

- * Steve Whitehouse: Now conninits have the "return" bit set.
- * Steve Whitehouse: Fixes to check alloc'd skbs are non NULL!
- * Moved output state machine into one function
- * Steve Whitehouse: New output state machine
- * Paul Koning: Connect Confirm message fix.
- * Eduardo Serrat: Fix to stop dn_nsp_do_disc() sending malformed packets.
- * Steve Whitehouse: dn_nsp_output() and friends needed a spring clean

- * DECnet An implementation of the DECnet protocol suite for the LINUX
- * operating system. DECnet is implemented using the BSD Socket
- * interface as the means of communication with the user level.
- *
- * DECnet Routing Functions (Endnode and Router)
- *
- * Authors: Steve Whitehouse <SteveW@ACM.org>
- * Eduardo Marcelo Serrat <emserrat@geocities.com>
- *
- * Changes:
- * Steve Whitehouse : Fixes to allow "intra-ethernet" and
- * "return-to-sender" bits on outgoing
- * packets.
- * Steve Whitehouse : Timeouts for cached routes.
- * Steve Whitehouse : Use dst cache for input routes too.
- * Steve Whitehouse : Fixed error values in dn_send_skb.
- * Steve Whitehouse : Rework routing functions to better fit
- * DECnet routing design
- * Alexey Kuznetsov : New SMP locking
- * Steve Whitehouse : More SMP locking changes & dn_cache_dump()
- * Steve Whitehouse : Prerouting NF hook, now really is prerouting.
- * Fixed possible skb leak in rtnetlink funcs.
- * Steve Whitehouse : Dave Miller's dynamic hash table sizing and
- * Alexey Kuznetsov's finer grained locking
- * from ipv4/route.c.
- * Steve Whitehouse : Routing is now starting to look like a
- * sensible set of code now, mainly due to
- * my copying the IPv4 routing code. The
- * hooks here are modified and will continue
- * to evolve for a while.
- * Steve Whitehouse : Real SMP at last :-) Also new netfilter
- * stuff. Look out raw sockets your days
- * are numbered!
- * Steve Whitehouse : Added return-to-sender functions. Added
- * backlog congestion level return codes.
- * Steve Whitehouse : Fixed bug where routes were set up with
- * no ref count on net devices.
- * Steve Whitehouse : RCU for the route cache
- * Steve Whitehouse : Preparations for the flow cache
- * Steve Whitehouse : Prepare for nonlinear skbs

+ *
+ * User ports with no phy-handle or fixed-link are expected to connect to an
+ * internal PHY located on the ds->slave_mii_bus at an MDIO address equal to
+ * the port number. This description is still actively supported.
+ *
+ * Shared (CPU and DSA) ports with no phy-handle or fixed-link are expected to
+ * operate at the maximum speed that their phy-mode is capable of. If the
+ * phy-mode is absent, they are expected to operate using the phy-mode
+ * supported by the port that gives the highest link speed. It is unspecified
+ * if the port should use flow control or not, half duplex or full duplex, or
+ * if the phy-mode is a SERDES link, whether in-band autoneg is expected to be
+ * enabled or not.
+ *
+ * In the latter case of shared ports, omitting the link management description
+ * from the firmware node is deprecated and strongly discouraged. DSA uses
+ * phylink, which rejects the firmware nodes of these ports for lacking
+ * required properties.
+ *
+ * For switches in this table, DSA will skip enforcing validation and will
+ * later omit registering a phylink instance for the shared ports, if they lack
+ * a fixed-link, a phy-handle, or a managed = "in-band-status" property.
+ * It becomes the responsibility of the driver to ensure that these ports
+ * operate at the maximum speed (whatever this means) and will interoperate
+ * with the DSA master or other cascade port, since phylink methods will not be
+ * invoked for them.
+ *
+ * If you are considering expanding this table for newly introduced switches,
+ * think again. It is OK to remove switches from this table if there aren't DT
+ * blobs in circulation which rely on defaulting the shared ports.

+# This prepares a custom sysroot with our custom `alloc` instead of
+# the standard one.
+#
+# This requires several hacks:
+# - Unlike `core` and `alloc`, `std` depends on more than a dozen crates,
+# including third-party crates that need to be downloaded, plus custom
+# `build.rs` steps. Thus hardcoding things here is not maintainable.
+# - `cargo` knows how to build the standard library, but it is an unstable
+# feature so far (`-Zbuild-std`).
+# - `cargo` only considers the use case of building the standard library
+# to use it in a given package. Thus we need to create a dummy package
+# and pick the generated libraries from there.
+# - Since we only keep a subset of upstream `alloc` in-tree, we need
+# to recreate it on the fly by putting our sources on top.
+# - The usual ways of modifying the dependency graph in `cargo` do not seem
+# to apply for the `-Zbuild-std` steps, thus we have to mislead it
+# by modifying the sources in the sysroot.
+# - To avoid messing with the user's Rust installation, we create a clone
+# of the sysroot. However, `cargo` ignores `RUSTFLAGS` in the `-Zbuild-std`
+# steps, thus we use a wrapper binary passed via `RUSTC` to pass the flag.
+#
+# In the future, we hope to avoid the whole ordeal by either:
+# - Making the `test` crate not depend on `std` (either improving upstream
+# or having our own custom crate).
+# - Making the tests run in kernel space (requires the previous point).
+# - Making `std` and friends be more like a "normal" crate, so that
+# `-Zbuild-std` and related hacks are not needed.

+# `alloc`
+
+These source files come from the Rust standard library, hosted in
+the <https://github.com/rust-lang/rust> repository, licensed under
+"Apache-2.0 OR MIT" and adapted for kernel use. For copyright details,
+see <https://github.com/rust-lang/rust/blob/master/COPYRIGHT>.
+
+Please note that these files should be kept as close as possible to
+upstream. In general, only additions should be performed (e.g. new
+methods). Eventually, changes should make it into upstream so that,
+at some point, this fork can be dropped from the kernel tree.
+
+
+## Rationale
+
+On one hand, kernel folks wanted to keep `alloc` in-tree to have more
+freedom in both workflow and actual features if actually needed
+(e.g. receiver types if we ended up using them), which is reasonable.
+
+On the other hand, Rust folks wanted to keep `alloc` as close as
+upstream as possible and avoid as much divergence as possible, which
+is also reasonable.
+
+We agreed on a middle-ground: we would keep a subset of `alloc`
+in-tree that would be as small and as close as possible to upstream.
+Then, upstream can start adding the functions that we add to `alloc`
+etc., until we reach a point where the kernel already knows exactly
+what it needs in `alloc` and all the new methods are merged into
+upstream, so that we can drop `alloc` from the kernel tree and go back
+to using the upstream one.
+
+By doing this, the kernel can go a bit faster now, and Rust can
+slowly incorporate and discuss the changes as needed.

+/// `Cow` implements `Deref`, which means that you can call
+/// non-mutating methods directly on the data it encloses. If mutation
+/// is desired, `to_mut` will obtain a mutable reference to an owned
+/// value, cloning if necessary.
+///
+/// If you need reference-counting pointers, note that
+/// [`Rc::make_mut`][crate::rc::Rc::make_mut] and
+/// [`Arc::make_mut`][crate::sync::Arc::make_mut] can provide clone-on-write
+/// functionality as well.
+///
+/// # Examples
+///
+/// ```
+/// use std::borrow::Cow;
+///
+/// fn abs_all(input: &mut Cow<[i32]>) {
+/// for i in 0..input.len() {
+/// let v = input[i];
+/// if v < 0 {
+/// // Clones into a vector if not already owned.
+/// input.to_mut()[i] = -v;
+/// }
+/// }
+/// }
+///
+/// // No clone occurs because `input` doesn't need to be mutated.
+/// let slice = [0, 1, 2];
+/// let mut input = Cow::from(&slice[..]);
+/// abs_all(&mut input);
+///
+/// // Clone occurs because `input` needs to be mutated.
+/// let slice = [-1, 0, 1];
+/// let mut input = Cow::from(&slice[..]);

+///
+/// // No clone occurs because `input` is already owned.
+/// let mut input = Cow::from(vec![-1, 0, 1]);

+//!
+//! # Examples
+//!
+//! Move a value from the stack to the heap by creating a [`Box`]:

+//! ```
+//! let val: u8 = 5;
+//! let boxed: Box<u8> = Box::new(val);

+//!
+//! ```
+//! let boxed: Box<u8> = Box::new(5);
+//! let val: u8 = *boxed;
+//! ```
+//!
+//! Creating a recursive data structure:
+//!
+//! ```
+//! #[derive(Debug)]
+//! enum List<T> {
+//! Cons(T, Box<List<T>>),
+//! Nil,

+//! let list: List<i32> = List::Cons(1, Box::new(List::Cons(2, Box::new(List::Nil))));
+//! println!("{list:?}");

+//! This will print `Cons(1, Cons(2, Nil))`.

+//! Cons(T, List<T>),
+//! # }
+//! ```
+//!
+//! It wouldn't work. This is because the size of a `List` depends on how many
+//! elements are in the list, and so we don't know how much memory to allocate
+//! for a `Cons`. By introducing a [`Box<T>`], which has a defined size, we know how
+//! big `Cons` needs to be.
+//!
+//! # Memory layout
+//!
+//! For non-zero-sized values, a [`Box`] will use the [`Global`] allocator for
+//! its allocation. It is valid to convert both ways between a [`Box`] and a
+//! raw pointer allocated with the [`Global`] allocator, given that the
+//! [`Layout`] used with the allocator is correct for the type. More precisely,
+//! a `value: *mut T` that has been allocated with the [`Global`] allocator
+//! with `Layout::for_value(&*value)` may be converted into a box using
+//! [`Box::<T>::from_raw(value)`]. Conversely, the memory backing a `value: *mut
+//! T` obtained from [`Box::<T>::into_raw`] may be deallocated using the
+//! [`Global`] allocator with [`Layout::for_value(&*value)`].
+//!
+//! For zero-sized values, the `Box` pointer still has to be [valid] for reads
+//! and writes and sufficiently aligned. In particular, casting any aligned
+//! non-zero integer literal to a raw pointer produces a valid pointer, but a
+//! pointer pointing into previously allocated memory that since got freed is
+//! not valid. The recommended way to build a Box to a ZST if `Box::new` cannot
+//! be used is to use [`ptr::NonNull::dangling`].
+//!
+//! So long as `T: Sized`, a `Box<T>` is guaranteed to be represented
+//! as a single pointer and is also ABI-compatible with C pointers
+//! (i.e. the C type `T*`). This means that if you have extern "C"
+//! Rust functions that will be called from C, you can define those
+//! Rust functions using `Box<T>` types, and use `T*` as corresponding
+//! type on the C side. As an example, consider this C header which
+//! declares functions that create and destroy some kind of `Foo`
+//! value:
+//!
+//! ```c
+//! /* C header */
+//!
+//! /* Returns ownership to the caller */
+//! struct Foo* foo_new(void);
+//!
+//! /* Takes ownership from the caller; no-op when invoked with null */
+//! void foo_delete(struct Foo*);
+//! ```
+//!
+//! These two functions might be implemented in Rust as follows. Here, the
+//! `struct Foo*` type from C is translated to `Box<Foo>`, which captures
+//! the ownership constraints. Note also that the nullable argument to
+//! `foo_delete` is represented in Rust as `Option<Box<Foo>>`, since `Box<Foo>`
+//! cannot be null.
+//!
+//! ```
+//! #[repr(C)]
+//! pub struct Foo;
+//!
+//! #[no_mangle]
+//! pub extern "C" fn foo_new() -> Box<Foo> {
+//! Box::new(Foo)
+//! }
+//!
+//! #[no_mangle]
+//! pub extern "C" fn foo_delete(_: Option<Box<Foo>>) {}
+//! ```
+//!
+//! Even though `Box<T>` has the same representation and C ABI as a C pointer,
+//! this does not mean that you can convert an arbitrary `T*` into a `Box<T>`
+//! and expect things to work. `Box<T>` values will always be fully aligned,
+//! non-null pointers. Moreover, the destructor for `Box<T>` will attempt to
+//! free the value with the global allocator. In general, the best practice
+//! is to only use `Box<T>` for pointers that originated from the global
+//! allocator.
+//!
+//! **Important.** At least at present, you should avoid using
+//! `Box<T>` types for functions that are defined in C but invoked
+//! from Rust. In those cases, you should directly mirror the C types
+//! as closely as possible. Using types like `Box<T>` where the C
+//! definition is just using `T*` can lead to undefined behavior, as
+//! described in [rust-lang/unsafe-code-guidelines#198][ucg#198].

+ *
+ * We chose this API instead of the alternative for a few reasons:
+ * - Logically, it is helpful to understand pinning in regard to the
+ * memory region being pointed to. For this reason none of the
+ * standard library pointer types support projecting through a pin
+ * (Box<T> is the only pointer type in std for which this would be
+ * safe.)
+ * - It is in practice very useful to have Box<T> be unconditionally
+ * Unpin because of trait objects, for which the structural auto
+ * trait functionality does not apply (e.g., Box<dyn Foo> would
+ * otherwise not be Unpin).
+ *
+ * Another type with the same semantics as Box but only a conditional
+ * implementation of `Unpin` (where `T: Unpin`) would be valid/safe, and
+ * could have a method to project a Pin<T> from it.

+
+//! # The Rust core allocation and collections library
+//!
+//! This library provides smart pointers and collections for managing
+//! heap-allocated values.
+//!
+//! This library, like libcore, normally doesn’t need to be used directly
+//! since its contents are re-exported in the [`std` crate](../std/index.html).
+//! Crates that use the `#![no_std]` attribute however will typically
+//! not depend on `std`, so they’d use this crate instead.
+//!
+//! ## Boxed values
+//!
+//! The [`Box`] type is a smart pointer type. There can only be one owner of a
+//! [`Box`], and the owner can decide to mutate the contents, which live on the
+//! heap.
+//!
+//! This type can be sent among threads efficiently as the size of a `Box` value
+//! is the same as that of a pointer. Tree-like data structures are often built
+//! with boxes because each node often has only one owner, the parent.
+//!
+//! ## Reference counted pointers
+//!
+//! The [`Rc`] type is a non-threadsafe reference-counted pointer type intended
+//! for sharing memory within a thread. An [`Rc`] pointer wraps a type, `T`, and
+//! only allows access to `&T`, a shared reference.
+//!
+//! This type is useful when inherited mutability (such as using [`Box`]) is too
+//! constraining for an application, and is often paired with the [`Cell`] or
+//! [`RefCell`] types in order to allow mutation.
+//!
+//! ## Atomically reference counted pointers
+//!
+//! The [`Arc`] type is the threadsafe equivalent of the [`Rc`] type. It
+//! provides all the same functionality of [`Rc`], except it requires that the
+//! contained type `T` is shareable. Additionally, [`Arc<T>`][`Arc`] is itself
+//! sendable while [`Rc<T>`][`Rc`] is not.
+//!
+//! This type allows for shared access to the contained data, and is often
+//! paired with synchronization primitives such as mutexes to allow mutation of
+//! shared resources.
+//!
+//! ## Collections
+//!
+//! Implementations of the most common general purpose data structures are
+//! defined in this library. They are re-exported through the
+//! [standard collections library](../std/collections/index.html).
+//!
+//! ## Heap interfaces
+//!
+//! The [`alloc`](alloc/index.html) module defines the low-level interface to the
+//! default global allocator. It is not compatible with the libc allocator API.
+//!
+//! [`Arc`]: sync
+//! [`Box`]: boxed
+//! [`Cell`]: core::cell
+//! [`Rc`]: rc
+//! [`RefCell`]: core::cell

+
+//! A dynamically-sized view into a contiguous sequence, `[T]`.
+//!
+//! *[See also the slice primitive type](slice).*
+//!
+//! Slices are a view into a block of memory represented as a pointer and a
+//! length.
+//!
+//! ```
+//! // slicing a Vec
+//! let vec = vec![1, 2, 3];
+//! let int_slice = &vec[..];
+//! // coercing an array to a slice
+//! let str_slice: &[&str] = &["one", "two", "three"];
+//! ```
+//!
+//! Slices are either mutable or shared. The shared slice type is `&[T]`,
+//! while the mutable slice type is `&mut [T]`, where `T` represents the element
+//! type. For example, you can mutate the block of memory that a mutable slice
+//! points to:
+//!
+//! ```
+//! let x = &mut [1, 2, 3];
+//! x[1] = 7;
+//! assert_eq!(x, &[1, 7, 3]);
+//! ```
+//!
+//! Here are some of the things this module contains:
+//!
+//! ## Structs
+//!
+//! There are several structs that are useful for slices, such as [`Iter`], which
+//! represents iteration over a slice.
+//!
+//! ## Trait Implementations
+//!
+//! There are several implementations of common traits for slices. Some examples
+//! include:
+//!
+//! * [`Clone`]
+//! * [`Eq`], [`Ord`] - for slices whose element type are [`Eq`] or [`Ord`].
+//! * [`Hash`] - for slices whose element type is [`Hash`].
+//!
+//! ## Iteration
+//!
+//! The slices implement `IntoIterator`. The iterator yields references to the
+//! slice elements.
+//!
+//! ```
+//! let numbers = &[0, 1, 2];
+//! for n in numbers {
+//! println!("{n} is a number!");
+//! }
+//! ```
+//!
+//! The mutable slice yields mutable references to the elements:
+//!
+//! ```
+//! let mut scores = [7, 8, 9];
+//! for score in &mut scores[..] {
+//! *score += 1;
+//! }
+//! ```
+//!
+//! This iterator yields mutable references to the slice's elements, so while
+//! the element type of the slice is `i32`, the element type of the iterator is
+//! `&mut i32`.
+//!
+//! * [`.iter`] and [`.iter_mut`] are the explicit methods to return the default
+//! iterators.
+//! * Further methods that return iterators are [`.split`], [`.splitn`],
+//! [`.chunks`], [`.windows`] and more.
+//!
+//! [`Hash`]: core::hash::Hash
+//! [`.iter`]: slice::iter
+//! [`.iter_mut`]: slice::iter_mut
+//! [`.split`]: slice::split
+//! [`.splitn`]: slice::splitn
+//! [`.chunks`]: slice::chunks
+//! [`.windows`]: slice::windows

+/// vec.resize(5, 0);
+/// assert_eq!(vec, [0, 0, 0, 0, 0]);
+/// ```
+///
+/// For more information, see
+/// [Capacity and Reallocation](#capacity-and-reallocation).
+///
+/// Use a `Vec<T>` as an efficient stack:
+///
+/// ```
+/// let mut stack = Vec::new();
+///
+/// stack.push(1);
+/// stack.push(2);
+/// stack.push(3);
+///
+/// while let Some(top) = stack.pop() {
+/// // Prints 3, 2, 1
+/// println!("{top}");
+/// }
+/// ```
+///
+/// # Indexing
+///
+/// The `Vec` type allows to access values by index, because it implements the
+/// [`Index`] trait. An example will be more explicit:
+///
+/// ```
+/// let v = vec![0, 2, 4, 6];
+/// println!("{}", v[1]); // it will display '2'
+/// ```
+///
+/// However be careful: if you try to access an index which isn't in the `Vec`,
+/// your software will panic! You cannot do this:
+///
+/// ```should_panic
+/// let v = vec![0, 2, 4, 6];
+/// println!("{}", v[6]); // it will panic!
+/// ```
+///
+/// Use [`get`] and [`get_mut`] if you want to check whether the index is in
+/// the `Vec`.
+///
+/// # Slicing
+///
+/// A `Vec` can be mutable. On the other hand, slices are read-only objects.
+/// To get a [slice][prim@slice], use [`&`]. Example:
+///
+/// ```
+/// fn read_slice(slice: &[usize]) {
+/// // ...
+/// }
+///
+/// let v = vec![0, 1];
+/// read_slice(&v);
+///
+/// // ... and that's all!
+/// // you can also do it like this:
+/// let u: &[usize] = &v;
+/// // or like this:
+/// let u: &[_] = &v;
+/// ```
+///
+/// In Rust, it's more common to pass slices as arguments rather than vectors
+/// when you just want to provide read access. The same goes for [`String`] and
+/// [`&str`].
+///
+/// # Capacity and reallocation
+///
+/// The capacity of a vector is the amount of space allocated for any future
+/// elements that will be added onto the vector. This is not to be confused with
+/// the *length* of a vector, which specifies the number of actual elements
+/// within the vector. If a vector's length exceeds its capacity, its capacity
+/// will automatically be increased, but its elements will have to be
+/// reallocated.
+///
+/// For example, a vector with capacity 10 and length 0 would be an empty vector
+/// with space for 10 more elements. Pushing 10 or fewer elements onto the
+/// vector will not change its capacity or cause reallocation to occur. However,
+/// if the vector's length is increased to 11, it will have to reallocate, which
+/// can be slow. For this reason, it is recommended to use [`Vec::with_capacity`]
+/// whenever possible to specify how big the vector is expected to get.
+///
+/// # Guarantees
+///
+/// Due to its incredibly fundamental nature, `Vec` makes a lot of guarantees
+/// about its design. This ensures that it's as low-overhead as possible in
+/// the general case, and can be correctly manipulated in primitive ways
+/// by unsafe code. Note that these guarantees refer to an unqualified `Vec<T>`.
+/// If additional type parameters are added (e.g., to support custom allocators),
+/// overriding their defaults may change the behavior.
+///
+/// Most fundamentally, `Vec` is and always will be a (pointer, capacity, length)
+/// triplet. No more, no less. The order of these fields is completely
+/// unspecified, and you should use the appropriate methods to modify these.
+/// The pointer will never be null, so this type is null-pointer-optimized.
+///
+/// However, the pointer might not actually point to allocated memory. In particular,
+/// if you construct a `Vec` with capacity 0 via [`Vec::new`], [`vec![]`][`vec!`],
+/// [`Vec::with_capacity(0)`][`Vec::with_capacity`], or by calling [`shrink_to_fit`]
+/// on an empty Vec, it will not allocate memory. Similarly, if you store zero-sized
+/// types inside a `Vec`, it will not allocate space for them. *Note that in this case
+/// the `Vec` might not report a [`capacity`] of 0*. `Vec` will allocate if and only
+/// if <code>[mem::size_of::\<T>]\() * [capacity]\() > 0</code>. In general, `Vec`'s allocation
+/// details are very subtle --- if you intend to allocate memory using a `Vec`
+/// and use it for something else (either to pass to unsafe code, or to build your
+/// own memory-backed collection), be sure to deallocate this memory by using
+/// `from_raw_parts` to recover the `Vec` and then dropping it.
+///
+/// If a `Vec` *has* allocated memory, then the memory it points to is on the heap
+/// (as defined by the allocator Rust is configured to use by default), and its
+/// pointer points to [`len`] initialized, contiguous elements in order (what
+/// you would see if you coerced it to a slice), followed by <code>[capacity] - [len]</code>
+/// logically uninitialized, contiguous elements.
+///
+/// A vector containing the elements `'a'` and `'b'` with capacity 4 can be
+/// visualized as below. The top part is the `Vec` struct, it contains a
+/// pointer to the head of the allocation in the heap, length and capacity.
+/// The bottom part is the allocation on the heap, a contiguous memory block.
+///
+/// ```text
+/// ptr len capacity
+/// +--------+--------+--------+
+/// | 0x0123 | 2 | 4 |
+/// +--------+--------+--------+
+/// |
+/// v
+/// Heap +--------+--------+--------+--------+
+/// | 'a' | 'b' | uninit | uninit |
+/// +--------+--------+--------+--------+
+/// ```
+///
+/// - **uninit** represents memory that is not initialized, see [`MaybeUninit`].
+/// - Note: the ABI is not stable and `Vec` makes no guarantees about its memory
+/// layout (including the order of fields).
+///
+/// `Vec` will never perform a "small optimization" where elements are actually
+/// stored on the stack for two reasons:
+///
+/// * It would make it more difficult for unsafe code to correctly manipulate
+/// a `Vec`. The contents of a `Vec` wouldn't have a stable address if it were
+/// only moved, and it would be more difficult to determine if a `Vec` had
+/// actually allocated memory.
+///
+/// * It would penalize the general case, incurring an additional branch
+/// on every access.
+///
+/// `Vec` will never automatically shrink itself, even if completely empty. This
+/// ensures no unnecessary allocations or deallocations occur. Emptying a `Vec`
+/// and then filling it back up to the same [`len`] should incur no calls to
+/// the allocator. If you wish to free up unused memory, use
+/// [`shrink_to_fit`] or [`shrink_to`].
+///
+/// [`push`] and [`insert`] will never (re)allocate if the reported capacity is
+/// sufficient. [`push`] and [`insert`] *will* (re)allocate if
+/// <code>[len] == [capacity]</code>. That is, the reported capacity is completely
+/// accurate, and can be relied on. It can even be used to manually free the memory
+/// allocated by a `Vec` if desired. Bulk insertion methods *may* reallocate, even
+/// when not necessary.
+///
+/// `Vec` does not guarantee any particular growth strategy when reallocating
+/// when full, nor when [`reserve`] is called. The current strategy is basic
+/// and it may prove desirable to use a non-constant growth factor. Whatever
+/// strategy is used will of course guarantee *O*(1) amortized [`push`].
+///
+/// `vec![x; n]`, `vec![a, b, c, d]`, and
+/// [`Vec::with_capacity(n)`][`Vec::with_capacity`], will all produce a `Vec`
+/// with exactly the requested capacity. If <code>[len] == [capacity]</code>,
+/// (as is the case for the [`vec!`] macro), then a `Vec<T>` can be converted to
+/// and from a [`Box<[T]>`][owned slice] without reallocating or moving the elements.
+///
+/// `Vec` will not specifically overwrite any data that is removed from it,
+/// but also won't specifically preserve it. Its uninitialized memory is
+/// scratch space that it may use however it wants. It will generally just do
+/// whatever is most efficient or otherwise easy to implement. Do not rely on
+/// removed data to be erased for security purposes. Even if you drop a `Vec`, its
+/// buffer may simply be reused by another allocation. Even if you zero a `Vec`'s memory
+/// first, that might not actually happen because the optimizer does not consider
+/// this a side-effect that must be preserved. There is one case which we will
+/// not break, however: using `unsafe` code to write to the excess capacity,
+/// and then increasing the length to match, is always valid.
+///
+/// Currently, `Vec` does not guarantee the order in which elements are dropped.
+/// The order has changed in the past and may change again.

+ * BPF_PROG2 is an enhanced version of BPF_PROG in order to handle struct

+ * in the trampoline stack, argument type size is needed to place proper number
+ * of u64 values for each argument. Therefore, BPF_PROG2 has different
+ * syntax from BPF_PROG. For example, for the following BPF_PROG syntax:
+ *
+ * int BPF_PROG(test2, int a, int b) { ... }
+ *
+ * the corresponding BPF_PROG2 syntax is:
+ *
+ * int BPF_PROG2(test2, int, a, int, b) { ... }
+ *
+ * where type and the corresponding argument name are separated by comma.
+ *
+ * Use BPF_PROG2 macro if one of the arguments might be a struct/union larger
+ * than 8 bytes:
+ *
+ * int BPF_PROG2(test_struct_arg, struct bpf_testmod_struct_arg_1, a, int, b,
+ * int, c, int, d, struct bpf_testmod_struct_arg_2, e, int, ret)

carrying a dependency, then the compiler can break that dependency
by substituting a constant of that value.
- Conversely, LKMM sometimes doesn't recognize that a particular
- optimization is not allowed, and as a result, thinks that a
- dependency is not present (because the optimization would break it).
- The memory model misses some pretty obvious control dependencies
- because of this limitation. A simple example is:
+ Conversely, LKMM will sometimes overestimate the amount of
+ reordering compilers and CPUs can carry out, leading it to miss
+ some pretty obvious cases of ordering. A simple example is:
r1 = READ_ONCE(x);
if (r1 == 0)
smp_mb();
WRITE_ONCE(y, 1);
- There is a control dependency from the READ_ONCE to the WRITE_ONCE,
- even when r1 is nonzero, but LKMM doesn't realize this and thinks
- that the write may execute before the read if r1 != 0. (Yes, that
- doesn't make sense if you think about it, but the memory model's
- intelligence is limited.)
+ The WRITE_ONCE() does not depend on the READ_ONCE(), and as a
+ result, LKMM does not claim ordering. However, even though no
+ dependency is present, the WRITE_ONCE() will not be executed before
+ the READ_ONCE(). There are two reasons for this:
+
+ The presence of the smp_mb() in one of the branches
+ prevents the compiler from moving the WRITE_ONCE()
+ up before the "if" statement, since the compiler has
+ to assume that r1 will sometimes be 0 (but see the
+ comment below);
+
+ CPUs do not execute stores before po-earlier conditional
+ branches, even in cases where the store occurs after the
+ two arms of the branch have recombined.
+
+ It is clear that it is not dangerous in the slightest for LKMM to
+ make weaker guarantees than architectures. In fact, it is
+ desirable, as it gives compilers room for making optimizations.
+ For instance, suppose that a 0 value in r1 would trigger undefined
+ behavior elsewhere. Then a clever compiler might deduce that r1
+ can never be 0 in the if condition. As a result, said clever
+ compiler might deem it safe to optimize away the smp_mb(),
+ eliminating the branch and any ordering an architecture would
+ guarantee otherwise.
2. Multiple access sizes for a single variable are not supported,
and neither are misaligned or partially overlapping accesses.

+ * This test makes sure BPF stats collection using rstat works correctly.
+ * The test uses 3 BPF progs:
+ * (a) counter: This BPF prog is invoked every time we attach a process to a
+ * cgroup and locklessly increments a percpu counter.
+ * The program then calls cgroup_rstat_updated() to inform rstat
+ * of an update on the (cpu, cgroup) pair.
+ *
+ * (b) flusher: This BPF prog is invoked when an rstat flush is ongoing, it
+ * aggregates all percpu counters to a total counter, and also
+ * propagates the changes to the ancestor cgroups.
+ *
+ * (c) dumper: This BPF prog is a cgroup_iter. It is used to output the total
+ * counter of a cgroup through reading a file in userspace.
+ *
+ * The test sets up a cgroup hierarchy, and the above programs. It spawns a few
+ * processes in the leaf cgroups and makes sure all the counters are aggregated
+ * correctly.

-# This test sends 1Gbps of traffic through the switch, into which it then
-# injects a burst of traffic and tests that there are no drops.
-#
-# The 1Gbps stream is created by sending >1Gbps stream from H1. This stream
-# ingresses through $swp1, and is forwarded thtrough a small temporary pool to a
-# 1Gbps $swp3.
-#
-# Thus a 1Gbps stream enters $swp4, and is forwarded through a large pool to
-# $swp2, and eventually to H2. Since $swp2 is a 1Gbps port as well, no backlog
-# is generated.
-#
-# At this point, a burst of traffic is forwarded from H3. This enters $swp5, is
-# forwarded to $swp2, which is fully subscribed by the 1Gbps stream. The
-# expectation is that the burst is wholly absorbed by the large pool and no
-# drops are caused. After the burst, there should be a backlog that is hard to
-# get rid of, because $sw2 is fully subscribed. But because each individual
-# packet is scheduled soon after getting enqueued, SLL and HLL do not impact the
-# test.

-# runs out of the descriptor buffer space with default configuration.
-#
-# The machine therefore needs to be able to produce line rate with as small

+# This script is designed for testing the support of NEXT-C-SID flavor for SRv6
+# End behavior.
+# A basic knowledge of SRv6 architecture [1] and of the compressed SID approach
+# [2] is assumed for the reader.
+#
+# The network topology used in the selftest is depicted hereafter, composed by
+# two hosts and four routers. Hosts hs-1 and hs-2 are connected through an
+# IPv4/IPv6 L3 VPN service, offered by routers rt-1, rt-2, rt-3 and rt-4 using
+# the NEXT-C-SID flavor. The key components for such VPNs are:
+#
+# i) The SRv6 H.Encaps/H.Encaps.Red behaviors [1] apply SRv6 Policies on
+# traffic received by connected hosts, initiating the VPN tunnel;
+#
+# ii) The SRv6 End behavior [1] advances the active SID in the SID List
+# carried by the SRH;
+#
+# iii) The NEXT-C-SID mechanism [2] offers the possibility of encoding several
+# SRv6 segments within a single 128-bit SID address, referred to as a
+# Compressed SID (C-SID) container. In this way, the length of the SID
+# List can be drastically reduced.
+# The NEXT-C-SID is provided as a "flavor" of the SRv6 End behavior
+# which advances the current C-SID (i.e. the Locator-Node Function defined
+# in [2]) with the next one carried in the Argument, if available.
+# When no more C-SIDs are available in the Argument, the SRv6 End behavior
+# will apply the End function selecting the next SID in the SID List.
+#
+# iv) The SRv6 End.DT46 behavior [1] is used for removing the SRv6 Policy and,
+# thus, it terminates the VPN tunnel. Such a behavior is capable of
+# handling, at the same time, both tunneled IPv4 and IPv6 traffic.

+#
+# Local SID/C-SID table
+# =====================
+#
+# Each SRv6 router is configured with a Local SID/C-SID table in which
+# SIDs/C-SIDs are stored. Considering an SRv6 router rt-x, SIDs/C-SIDs are
+# configured in the Local SID/C-SIDs table as follows:
+#
+# Local SID/C-SID table for SRv6 router rt-x
+# +-----------------------------------------------------------+
+# |fcff:x::d46 is associated with the non-compressed SRv6 |
+# | End.DT46 behavior |
+# +-----------------------------------------------------------+
+# |fcbb:0:0x00::/48 is associated with the NEXT-C-SID flavor |
+# | of SRv6 End behavior |
+# +-----------------------------------------------------------+
+# |fcbb:0:0x00:d46::/64 is associated with the SRv6 End.DT46 |
+# | behavior when NEXT-C-SID compression is turned on |
+# +-----------------------------------------------------------+
+#
+# The fcff::/16 prefix is reserved for implementing SRv6 services with regular
+# (non compressed) SIDs. Reachability of SIDs is ensured by proper configuration
+# of the IPv6 routing tables in the routers.
+# Similarly, the fcbb:0::/32 prefix is reserved for implementing SRv6 VPN
+# services leveraging the NEXT-C-SID compression mechanism. Indeed, the
+# fcbb:0::/32 is used for encoding the Locator-Block while the Locator-Node
+# Function is encoded with 16 bits.
+#
+# Incoming traffic classification and application of SRv6 Policies
+# ================================================================
+#
+# An SRv6 ingress router applies different SRv6 Policies to the traffic received
+# from a connected host, considering the IPv4 or IPv6 destination address.
+# SRv6 policy enforcement consists of encapsulating the received traffic into a
+# new IPv6 packet with a given SID List contained in the SRH.
+# When the SID List contains only one SID, the SRH could be omitted completely
+# and that SID is stored directly in the IPv6 Destination Address (DA) (this is
+# called "reduced" encapsulation).
+#
+# Test cases for NEXT-C-SID
+# =========================
+#
+# We consider two test cases for NEXT-C-SID: i) single SID and ii) double SID.
+#
+# In the single SID test case we have a number of segments that are all
+# contained in a single Compressed SID (C-SID) container. Therefore the
+# resulting SID List has only one SID. Using the reduced encapsulation format
+# this will result in a packet with no SRH.
+#
+# In the double SID test case we have one segment carried in a Compressed SID
+# (C-SID) container, followed by a regular (non compressed) SID. The resulting
+# SID List has two segments and it is possible to test the advance to the next
+# SID when all the C-SIDs in a C-SID container have been processed. Using the
+# reduced encapsulation format this will result in a packet with an SRH
+# containing 1 segment.
+#
+# For the single SID test case, we use the IPv4 addresses of hs-1 and hs-2, for
+# the double SID test case, we use their IPv6 addresses. This is only done to
+# simplify the test setup and avoid adding other hosts or multiple addresses on
+# the same interface of a host.
+#
+# Traffic from hs-1 to hs-2
+# -------------------------
+#
+# Packets generated from hs-1 and directed towards hs-2 are handled by rt-1
+# which applies the SRv6 Policies as follows:
+#
+# i) IPv6 DA=cafe::2, H.Encaps.Red with SID List=fcbb:0:0400:0300:0200:d46::
+# ii) IPv4 DA=10.0.0.2, H.Encaps.Red with SID List=fcbb:0:0300::,fcff:2::d46
+#
+# ### i) single SID
+#
+# The router rt-1 is configured to enforce the given Policy through the SRv6
+# H.Encaps.Red behavior which avoids the presence of the SRH at all, since it
+# pushes the single SID directly in the IPv6 DA. Such a SID encodes a whole
+# C-SID container carrying several C-SIDs (e.g. 0400, 0300, etc).
+#
+# As the packet reaches the router rt-4, the enabled NEXT-C-SID SRv6 End
+# behavior (associated with fcbb:0:0400::/48) is triggered. This behavior
+# analyzes the IPv6 DA and checks whether the Argument of the C-SID container
+# is zero or not. In this case, the Argument is *NOT* zero and the IPv6 DA is
+# updated as follows:
+#
+# +---------------------------------------------------------------+
+# | Before applying the rt-4 enabled NEXT-C-SID SRv6 End behavior |
+# +---------------------------------------------------------------+
+# | +---------- Argument |
+# | vvvvvvvvvvvvvvvv |
+# | IPv6 DA fcbb:0:0400:0300:0200:d46:: |
+# | ^^^^ <-- shifting |
+# | | |
+# | Locator-Node Function |
+# +---------------------------------------------------------------+
+# | After applying the rt-4 enabled NEXT-C-SID SRv6 End behavior |
+# +---------------------------------------------------------------+
+# | +---------- Argument |
+# | vvvvvvvvvvvv |
+# | IPv6 DA fcbb:0:0300:0200:d46:: |
+# | ^^^^ |
+# | | |
+# | Locator-Node Function |
+# +---------------------------------------------------------------+
+#
+# After having applied the enabled NEXT-C-SID SRv6 End behavior, the packet is
+# sent to the next node, i.e. rt-3.
+#
+# The enabled NEXT-C-SID SRv6 End behavior on rt-3 is executed as the packet is
+# received. This behavior processes the packet and updates the IPv6 DA with
+# fcbb:0:0200:d46::, since the Argument is *NOT* zero. Then, the packet is sent
+# to the router rt-2.
+#
+# The router rt-2 is configured for decapsulating the inner IPv6 packet and,
+# for this reason, it applies the SRv6 End.DT46 behavior on the received
+# packet. It is worth noting that the SRv6 End.DT46 behavior does not require
+# the presence of the SRH: it is fully capable to operate properly on
+# IPv4/IPv6-in-IPv6 encapsulations.
+# At the end of the decap operation, the packet is sent to the
+# host hs-2.
+#
+# ### ii) double SID
+#
+# The router rt-1 is configured to enforce the given Policy through the SRv6
+# H.Encaps.Red. As a result, the first SID fcbb:0:0300:: is stored into the
+# IPv6 DA, while the SRH pushed into the packet is made of only one SID, i.e.
+# fcff:2::d46. Hence, the packet sent by hs-1 to hs-2 is encapsulated in an
+# outer IPv6 header plus the SRH.
+#
+# As the packet reaches the node rt-3, the router applies the enabled NEXT-C-SID
+# SRv6 End behavior.
+#
+# +---------------------------------------------------------------+
+# | Before applying the rt-3 enabled NEXT-C-SID SRv6 End behavior |
+# +---------------------------------------------------------------+
+# | +---------- Argument |
+# | vvvv (Argument is all filled with zeros) |
+# | IPv6 DA fcbb:0:0300:: |
+# | ^^^^ |
+# | | |
+# | Locator-Node Function |
+# +---------------------------------------------------------------+
+# | After applying the rt-3 enabled NEXT-C-SID SRv6 End behavior |
+# +---------------------------------------------------------------+
+# | |
+# | IPv6 DA fcff:2::d46 |
+# | ^^^^^^^^^^^ |
+# | | |
+# | SID copied from the SID List contained in the SRH |
+# +---------------------------------------------------------------+
+#
+# Since the Argument of the C-SID container is zero, the behavior can not
+# update the Locator-Node function with the next C-SID carried in the Argument
+# itself. Thus, the enabled NEXT-C-SID SRv6 End behavior operates as the
+# traditional End behavior: it updates the IPv6 DA by copying the next
+# available SID in the SID List carried by the SRH. After that, the packet is
+# sent to the node rt-2.
+#
+# Once the packet is received by rt-2, the router decapsulates the inner IPv6
+# packet using the SRv6 End.DT46 behavior (associated with the SID fcff:2::d46)
+# and sends it to the host hs-2.
+#
+# Traffic from hs-2 to hs-1
+# -------------------------
+#
+# Packets generated from hs-2 and directed towards hs-1 are handled by rt-2
+# which applies the SRv6 Policies as follows:
+#
+# i) IPv6 DA=cafe::1, SID List=fcbb:0:0300:0400:0100:d46::
+# ii) IPv4 DA=10.0.0.1, SID List=fcbb:0:0300::,fcff:1::d46
+#
+# For simplicity, such SRv6 Policies were chosen so that, in both use cases (i)
+# and (ii), the network paths crossed by traffic from hs-2 to hs-1 are the same
+# as those taken by traffic from hs-1 to hs-2.
+# In this way, traffic from hs-2 to hs-1 is processed similarly to traffic from
+# hs-1 to hs-2. So, the traffic processing scheme turns out to be the same as
+# that adopted in the use cases already examined (of course, it is necessary to
+# consider the different SIDs/C-SIDs).
