kernel, and, if supported, uses\nmulti-uprobes to improve USDT attachment speed.\n\nUSDTs can be attached system-wide or for the specific process by PID. In\nthe latter case, we rely on correct kernel logic of not triggering USDT\nfor unrelated processes.\n\nAs such, on older kernels that do support multi-uprobes, but still have\nbroken PID filtering logic, we need to fall back to singular uprobes.\n\nUnfortunately, whether user is using PID filtering or not is known at\nthe attachment time, which happens after relevant BPF programs were\nloaded into the kernel. Also unfortunately, we need to make a call\nwhether to use multi-uprobes or singular uprobe for SEC(\"usdt\") programs\nduring BPF object load time, at which point we have no information about\npossible PID filtering.\n\nThe distinction between single and multi-uprobes is small, but important\nfor the kernel. Multi-uprobes get BPF_TRACE_UPROBE_MULTI attach type,\nand kernel internally substitiute different implementation of some of\nBPF helpers (e.g., bpf_get_attach_cookie()) depending on whether uprobe\nis multi or singular. So, multi-uprobes and singular uprobes cannot be\nintermixed.\n\nAll the above implies that we have to make an early and conservative\ncall about the use of multi-uprobes. And so this patch modifies libbpf\u0027s\nexisting feature detector for multi-uprobe support to also check correct\nPID filtering.

User space mmap-s bpf_arena and uses it as a traditional mmap-ed\n anonymous region, like memcached or any key/value storage. The bpf\n program implements an in-kernel accelerator. XDP prog can search for\n a key in bpf_arena and return a value without going to user space.\n2. The bpf program builds arbitrary data structures in bpf_arena (hash\n tables, rb-trees, sparse arrays), while user space consumes it.\n3. bpf_arena is a \"heap\" of memory from the bpf program\u0027s point of view.\n The user space may mmap it, but bpf program will not convert pointers\n to user base at run-time to improve bpf program speed.\n\nInitially, the kernel vm_area and user vma are not populated. User space\ncan fault in pages within the range. While servicing a page fault,\nbpf_arena logic will insert a new page into the kernel and user vmas. The\nbpf program can allocate pages from that region via\nbpf_arena_alloc_pages(). This kernel function will insert pages into the\nkernel vm_area. The subsequent fault-in from user space will populate that\npage into the user vma. The BPF_F_SEGV_ON_FAULT flag at arena creation time\ncan be used to prevent fault-in from user space. In such a case, if a page\nis not allocated by the bpf program and not present in the kernel vm_area,\nthe user process will segfault. This is useful for use cases 2 and 3 above.\n\nbpf_arena_alloc_pages() is similar to user space mmap(). It allocates pages\neither at a specific address within the arena or allocates a range with the\nmaple tree. bpf_arena_free_pages() is analogous to munmap(), which frees\npages and removes the range from the kernel vm_area and from user process\nvmas.\n\nbpf_arena can be used as a bpf program \"heap\" of up to 4GB. The speed of\nbpf program is more important than ease of sharing with user space. This is\nuse case 3. In such a case, the BPF_F_NO_USER_CONV flag is recommended.\nIt will tell the verifier to treat the rX \u003d bpf_arena_cast_user(rY)\ninstruction as a 32-bit move wX \u003d wY, which will improve bpf prog\nperformance. Otherwise, bpf_arena_cast_user is translated by JIT to\nconditionally add the upper 32 bits of user vm_start (if the pointer is not\nNULL) to arena pointers before they are stored into memory. This way, user\nspace sees them as valid 64-bit pointers.\n\nDiff https://github.com/llvm/llvm-project/pull/84410 enables LLVM BPF\nbackend generate the bpf_addr_space_cast() instruction to cast pointers\nbetween address_space(1) which is reserved for bpf_arena pointers and\ndefault address space zero. All arena pointers in a bpf program written in\nC language are tagged as __attribute__((address_space(1))). Hence, clang\nprovides helpful diagnostics when pointers cross address space. Libbpf and\nthe kernel support only address_space \u003d\u003d 1. All other address space\nidentifiers are reserved.\n\nrX \u003d bpf_addr_space_cast(rY, /* dst_as */ 1, /* src_as */ 0) tells the\nverifier that rX-\u003etype \u003d PTR_TO_ARENA. Any further operations on\nPTR_TO_ARENA register have to be in the 32-bit domain. The verifier will\nmark load/store through PTR_TO_ARENA with PROBE_MEM32. JIT will generate\nthem as kern_vm_start + 32bit_addr memory accesses. The behavior is similar\nto copy_from_kernel_nofault() except that no address checks are necessary.\nThe address is guaranteed to be in the 4GB range. If the page is not\npresent, the destination register is zeroed on read, and the operation is\nignored on write.\n\nrX \u003d bpf_addr_space_cast(rY, 0, 1) tells the verifier that rX-\u003etype \u003d\nunknown scalar. If arena-\u003emap_flags has BPF_F_NO_USER_CONV set, then the\nverifier converts such cast instructions to mov32. Otherwise, JIT will emit\nnative code equivalent to:\nrX \u003d (u32)rY;\nif (rY)\n rX |\u003d clear_lo32_bits(arena-\u003euser_vm_start); /* replace hi32 bits in rX */\n\nAfter such conversion, the pointer becomes a valid user pointer within\nbpf_arena range. The user process can access data structures created in\nbpf_arena without any additional computations. For example, a linked list\nbuilt by a bpf program can be walked natively by user space.\n\nSigned-off-by: Alexei Starovoitov \u003cast@kernel.org\u003e\nSigned-off-by: Andrii Nakryiko \u003candrii@kernel.org\u003e\nReviewed-by: Barret Rhoden \u003cbrho@google.com\u003e\nLink: https://lore.kernel.org/bpf/20240308010812.89848-2-alexei.starovoitov@gmail.com\n" }, { "commit": "385d344839d9c25d4d7ff861b9ad8636ceeb0b95", "tree": "dff51bd8ec6e03293dec430215f3ac9df684b475", "parents": [ "d71c0ed2ef49514df395d914ab7706da6553fb0b" ], "author": { "name": "Alexei Starovoitov", "email": "ast@kernel.org", "time": "Wed Mar 06 19:12:26 2024 -0800" }, "committer": { "name": "Andrii Nakryiko", "email": "andrii.nakryiko@gmail.com", "time": "Mon Mar 25 21:58:26 2024 -0700" }, "message": "libbpf: Allow specifying 64-bit integers in map BTF.\n\n__uint() macro that is used to specify map attributes like:\n __uint(type, BPF_MAP_TYPE_ARRAY);\n __uint(map_flags, BPF_F_MMAPABLE);\nIt is limited to 32-bit, since BTF_KIND_ARRAY has u32 \"number of elements\"\nfield in \"struct btf_array\".\n\nIntroduce __ulong() macro that allows specifying values bigger than 32-bit.\nIn map definition \"map_extra\" is the only u64 field, so far.\n\nSigned-off-by: Alexei Starovoitov \u003cast@kernel.org\u003e\nLink: https://lore.kernel.org/r/20240307031228.42896-5-alexei.starovoitov@gmail.com\nSigned-off-by: Martin KaFai Lau \u003cmartin.lau@kernel.org\u003e\n" }, { "commit": "d71c0ed2ef49514df395d914ab7706da6553fb0b", "tree": "3b6edb6747eac6b74e606b499dd43b6289045aaf", "parents": [ "5e80833e509e10118ce69ddd36c6d13e4efe6909" ], "author": { "name": "Jakub Kicinski", "email": "kuba@kernel.org", "time": "Wed Mar 06 11:55:08 2024 -0800" }, "committer": { "name": "Andrii Nakryiko", "email": "andrii.nakryiko@gmail.com", "time": "Mon Mar 25 21:58:26 2024 -0700" }, "message": "netdev: add queue stat for alloc failures\n\nRx alloc failures are commonly counted by drivers.\nSupport reporting those via netdev-genl queue stats.\n\nAcked-by: Stanislav Fomichev \u003csdf@google.com\u003e\nReviewed-by: Amritha Nambiar \u003camritha.nambiar@intel.com\u003e\nReviewed-by: Xuan Zhuo \u003cxuanzhuo@linux.alibaba.com\u003e\nLink: https://lore.kernel.org/r/20240306195509.1502746-3-kuba@kernel.org\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\n" }, { "commit": "5e80833e509e10118ce69ddd36c6d13e4efe6909", "tree": "7d8666418b512ffa8c01dfdfa9817c3b9b7d532c", "parents": [ "2778cbce609aa1e2747a69349f7f46a2f94f0522" ], "author": { "name": "Jakub Kicinski", "email": "kuba@kernel.org", "time": "Wed Mar 06 11:55:07 2024 -0800" }, "committer": { "name": "Andrii Nakryiko", "email": "andrii.nakryiko@gmail.com", "time": "Mon Mar 25 21:58:26 2024 -0700" }, "message": "netdev: add per-queue statistics\n\nThe ethtool-nl family does a good job exposing various protocol\nrelated and IEEE/IETF statistics which used to get dumped under\nethtool -S, with creative names.

This\nenables a port to be in a state where it can receive incoming packets\nwhile not still distributing. This is useful for reducing packet loss when\na port begins distributing before its partner is able to collect.\n\nAdded new functions such as bond_set_slave_tx_disabled_flags and\nbond_set_slave_rx_enabled_flags to precisely manage the port\u0027s collecting\nand distributing states. Previously, there was no dedicated method to\ndisable TX while keeping RX enabled, which this patch addresses.\n\nNote that the regular flow process in the kernel\u0027s bonding driver remains\nunaffected by this patch. The extension requires explicit opt-in by the\nuser (in order to ensure no disruptions for existing setups) via netlink\nsupport using the new bonding parameter coupled_control. The default value\nfor coupled_control is set to 1 so as to preserve existing behaviour.\n\nSigned-off-by: Aahil Awatramani \u003caahila@google.com\u003e\nReviewed-by: Hangbin Liu \u003cliuhangbin@gmail.com\u003e\nLink: https://lore.kernel.org/r/20240202175858.1573852-1-aahila@google.com\nSigned-off-by: Paolo Abeni \u003cpabeni@redhat.com\u003e\n" }, { "commit": "fb98d4bd25f11f4960d7d2d218e4be200397417e", "tree": "14e21a5786fb35af0dfc0799ae2bfc2411eb97f1", "parents": [ "f4e9b606f4e2f1682e345a6ff9a9c4fe56147080" ], "author": { "name": "Andrii Nakryiko", "email": "andrii@kernel.org", "time": "Fri Mar 01 15:28:37 2024 -0800" }, "committer": { "name": "Andrii Nakryiko", "email": "andrii.nakryiko@gmail.com", "time": "Fri Mar 01 15:39:45 2024 -0800" }, "message": "include: fix BPF_CALL_REL definition\n\nFix our Github-specific definition of BPF_CALL_REL macro.
