the stop, just ignore the stop.\n\nThis makes our state tracking more accurate. Before, when a task is booted out of a ptrace-stop via SIGKILL or equivalent while we\u0027re reading its state in `Task::did_waitpid`, we would treat the task as as if it were still stopped, even though now it is either running in the kernel towards PTRACE_EVENT_EXIT or reap, or else stopped in a new PTRACE_EVENT_EXIT stop which we will see in the next wait(). We would cover up the discrepancy by changing the stop to a fake PTRACE_EVENT_EXIT. Instead we now \"tell the truth\" that the task is not known to be stopped and instead we should wait for its next stop.\n\nThe downside is that this requires us to propagate the fact that the task is not actually stopped to various callers, including the callers of `Task::resume_execution`. This is annoying, but it\u0027s also helpful to consider how these callers should behave when a task is booted out of a ptrace-stop by SIGKILL and is no longer stopped. It\u0027s complex and hard to test, but the underlying kernel behavior is the problem.\n" }, { "commit": "7f4d35a2af395777b71c96e2472728bf441a91e0", "tree": "b160e442cdc7deb1c2ce71b93fc00b47c9a42b03", "parents": [ "4d751148a650a66c75d7de3f5bcb926573b9b634" ], "author": { "name": "Robert O\u0027Callahan", "email": "robert@ocallahan.org", "time": "Sat Sep 09 09:10:17 2023 +1200" }, "committer": { "name": "Robert O\u0027Callahan", "email": "robert@ocallahan.org", "time": "Sat Sep 09 09:53:56 2023 +1200" }, "message": "Download Firefox release for testing instead of using the distro package, because on new Ubuntus Firefox is a Snap package which we don\u0027t support in rr yet\n" }, { "commit": "4d751148a650a66c75d7de3f5bcb926573b9b634", "tree": "94b8aae37b61fe3a9ee374e5bd6f861c6ae53cea", "parents": [ "1b4371d4167e4f4b574029cc075881b64184bbaa" ], "author": { "name": "Simon Sobisch", "email": "simonsobisch@web.de", "time": "Tue Sep 05 13:24:05 2023 +0200" }, "committer": { "name": "Robert O\u0027Callahan", "email": "robert@ocallahan.org", "time": "Sat Sep 09 08:31:08 2023 +1200" }, "message": "Update .gitignore\n\nto drop generated files" }, { "commit": "1b4371d4167e4f4b574029cc075881b64184bbaa", "tree": "4028bfd8f631c571ae9c57fd8e45f8d4db9dca77", "parents": [ "1afb318f1b8965b96ab9fe525a6b8807aa3c4be0" ], "author": { "name": "Robert O\u0027Callahan", "email": "robert@ocallahan.org", "time": "Sat Sep 09 08:06:08 2023 +1200" }, "committer": { "name": "Robert O\u0027Callahan", "email": "robert@ocallahan.org", "time": "Sat Sep 09 08:07:36 2023 +1200" }, "message": "Ensure that detached tasks are kicked out of their self-induced group-stop\n\nResolves #3597\n" }, { "commit": "1afb318f1b8965b96ab9fe525a6b8807aa3c4be0", "tree": "d42b6ce7b709f38e34712fb2057ba33060707528", "parents": [ "13b2274f8ddba292c27fd42257075b4a827c9236" ], "author": { "name": "Robert O\u0027Callahan", "email": "robert@ocallahan.org", "time": "Thu Sep 07 07:59:41 2023 +1200" }, "committer": { "name": "Robert O\u0027Callahan", "email": "robert@ocallahan.org", "time": "Thu Sep 07 08:02:15 2023 +1200" }, "message": "Rework register comparison API so that all register-difference output is emitted in a single log line\n\nCurrently when LOG(error) is fatal we lose output.

interfering branch heuristic\nby false-positive coincidence. Even more unfortunately, this is a calibration loop\nfor a tracing library, so it does actually just call `rdtsc` in a loop a bunch.\nAdditionally this is shipped as a binary, so every user is hitting this unfortunate coincidence.\nOf course, since we\u0027re shipping the library, I can suggest we modify the source to make\nit more friendly to rr patching. That said, I wasn\u0027t quite sure what would be best to suggest here.\n\nAt first I thought, I could simply insert a bunch of nops after.\nUnfortunately, that doesn\u0027t actually do anything, because the branch could still\nbe interfering into the middle of the nop sled.\nThen I thought maybe a singular large `nop` would be sufficient, but of course,\nthere could be something that intentionally conditionally skips the rdtsc.\n\nIn this PR, I propose that we make the following sequence known-safe:\n```\nnopl 0(%ax, %ax, 1) # single instruction, 5-byte nop\nrdtsc\n```\n\nThis currently wouldn\u0027t quite work, because an interfering jump to the\n`rdtsc` would simply hit the trailing nop padding, ignoring the rdtsc.\nHowever, if we slightly tweak the patch to instead use:\n\n```\n1: jmp %hook\n[usual nop padding here]\njmp 1b\n2:\n```\n\nThen everything works out well. Our return address is past the entire patch\nregion, so we return to the correct place and it doesn\u0027t matter whether\nwe jump to the nop or to the instruction itself. Of course, and actual\ninterfering branch over the nop is unlikely (though I supposed not\nimpossible depending on what comes before), since interfering branches\nare supported, this nicely takes care of the spurious branch problem\nabove (assuming the extra 5-byte nop is inserted).\n" }, { "commit": "55012fb240bec85902589a35f42865b8ecce4d4d", "tree": "2db0cd8c7272da935b7a2665b7948b8d013a06d6", "parents": [ "4af8558d6cf83c1ab747eb85e3adadc0c6a72ef6" ], "author": { "name": "Keno Fischer", "email": "keno@juliacomputing.com", "time": "Fri Aug 18 03:03:51 2023 -0400" }, "committer": { "name": "Robert O\u0027Callahan", "email": "robert@ocallahan.org", "time": "Sat Aug 19 12:47:09 2023 +1200" }, "message": "Fix detection of interfering branches for PATCH_SYSCALL_INSTRUCTION_IS_LAST\n\nThe interfering branch check was assuming that the syscall (or rdtsc\ninstruction) is at the start of the patch region.
