Due to an oversight in commit 1b3044e39a89 ("procfs: fix pthread cross-thread naming if !PR_DUMPABLE") in switching from REG to NOD, mode changes on /proc/thread-self/comm were accidently allowed. Similar, mode changes for all files beneath /proc/<pid>/net/ are blocked but mode changes on /proc/<pid>/net itself were accidently allowed. Both issues come down to not using the generic proc_setattr() helper which blocks all mode changes. This is rectified with this pull request. This also removes a strange nolibc test that abused /proc/<pid>/net for testing mode changes. Using procfs for this test never made a lot of sense given procfs has special semantics for almost everything anway. Both changes are minor user-visible changes.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull fchmodat2 system call from Christian Brauner: "This adds the fchmodat2() system call. It is a revised version of the fchmodat() system call, adding a missing flag argument. Support for both AT_SYMLINK_NOFOLLOW and AT_EMPTY_PATH are included. Adding this system call revision has been a longstanding request but so far has always fallen through the cracks. While the kernel implementation of fchmodat() does not have a flag argument the libc provided POSIX-compliant fchmodat(3) version does. Both glibc and musl have to implement a workaround in order to support AT_SYMLINK_NOFOLLOW (see [1] and [2]). The workaround is brittle because it relies not just on O_PATH and O_NOFOLLOW semantics and procfs magic links but also on our rather inconsistent symlink semantics. This gives userspace a proper fchmodat2() system call that libcs can use to properly implement fchmodat(3) and allows them to get rid of their hacks. In this case it will immediately benefit them as the current workaround is already defunct because of aformentioned inconsistencies. In addition to AT_SYMLINK_NOFOLLOW, give userspace the ability to use AT_EMPTY_PATH with fchmodat2(). This is already possible with fchownat() so there's no reason to not also support it for fchmodat2(). The implementation is simple and comes with selftests. Implementation of the system call and wiring up the system call are done as separate patches even though they could arguably be one patch.

2023-08-26tools: ynl-gen: fix uAPI generation after tempfile changesJakub Kicinski1-10/+20
We use a tempfile for code generation, to avoid wiping the target file out if the code generator crashes. File contents are copied from tempfile to actual destination at the end of main(). uAPI generation is relatively simple so when generating the uAPI header we return from main() early, and never reach the "copy code over" stage. Since commit under Fixes uAPI headers are not updated by ynl-gen. Move the copy/commit of the code into CodeWriter, to make it easier to call at any point in time. Hook it into the destructor to make sure we don't miss calling it.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix ring buffer being permanently disabled due to missed record_disabled() Changing the trace cpu mask will disable the ring buffers for the CPUs no longer in the mask. But it fails to update the snapshot buffer. If a snapshot takes place, the accounting for the ring buffer being disabled is corrupted and this can lead to the ring buffer being permanently disabled. - Add test case for snapshot and cpu mask working together - Fix memleak by the function graph tracer not getting closed properly. The iterator is used to read the ring buffer. When it opens, it calls the open function of a tracer, and when it is closed, it calls the close iteration. While a trace is being read, it is still possible to change the tracer. If this happens between the function graph tracer and the wakeup tracer (which uses function graph tracing), the tracers are not closed properly during when the iterator sees the switch, and the wakeup function did not initialize its private pointer to NULL, which is used to know if the function graph tracer was the last tracer. It could be fooled in thinking it is, but then on exit it does not call the close function of the function graph tracer to clean up its data. - Fix synthetic events on big endian machines, by introducing a union that does the conversions properly. - Fix synthetic events from printing out the number of elements in the stacktrace when it shouldn't. - Fix synthetic events stacktrace to not print a bogus value at the end. - Introduce a pipe_cpumask that prevents the trace_pipe files from being opened by more than one task (file descriptor). There was a race found where if splice is called, the iter->ent could become stale and events could be missed. There's no point reading a producer/consumer file by more than one task as they will corrupt each other anyway. Add a cpumask that keeps track of the per_cpu trace_pipe files as well as the global trace_pipe file that prevents more than one open of a trace_pipe file that represents the same ring buffer. This prevents the race from happening. - Fix ftrace samples for arm64 to work with older compilers. * tag 'trace-v6.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: samples: ftrace: Replace bti assembly with hint for older compiler tracing: Introduce pipe_cpumask to avoid race on trace_pipes tracing: Fix memleak due to race between current_tracer and trace tracing/synthetic: Allocate one additional element for size tracing/synthetic: Skip first entry for stack traces tracing/synthetic: Use union instead of casts selftests/ftrace: Add a basic testcase for snapshot tracing: Fix cpu buffers unavailable due to 'record_disabled' missed

2023-08-25selftests: cachestat: catch failing fsync test on tmpfsAndre Przywara1-15/+47
The cachestat kselftest runs a test on a normal file, which is created temporarily in the current directory. Among the tests it runs there is a call to fsync(), which is expected to clean all dirty pages used by the file. However the tmpfs filesystem implements fsync() as noop_fsync(), so the call will not even attempt to clean anything when this test file happens to live on a tmpfs instance. This happens in an initramfs, or when the current directory is in /dev/shm or sometimes /tmp. To avoid this test failing wrongly, use statfs() to check which filesystem the test file lives on. If that is "tmpfs", we skip the fsync() test. Since the fsync test is only one part of the "normal file" test, we now execute this twice, skipping the fsync part on the first call. This way only the second test, including the fsync part, would be skipped.

2023-08-25selftests: cachestat: test for cachestat availabilityAndre Przywara1-1/+19
Patch series "selftests: cachestat: fix run on older kernels", v2. I ran all kernel selftests on some test machine, and stumbled upon cachestat failing (among others). These patches fix the run on older kernels and when the current directory is on a tmpfs instance. This patch (of 2): As cachestat is a new syscall, it won't be available on older kernels, for instance those running on a development machine. At the moment the test reports all tests as "not ok" in this case. Test for the cachestat syscall availability first, before doing further tests, and bail out early with a TAP SKIP comment. This also uses the opportunity to add the proper TAP headers, and add one check for proper error handling (illegal file descriptor).
