[REGRESSION] cifs: triggers bad flatpak & ostree signatures, corrupts ffmpeg & mkvmerge outputs

by Forest

#regzbot introduced: 3ee1a1fc3981 Dear maintainers, I think I have found a cifs regression in the 6.10 kernel series, which leads certain programs to write corrupt data. After upgrading from kernel 6.9.12 to 6.10.6, flatpak and ostree are now writing bad gpg signatures when exporting signed packages or signing their repository metadata/summary files, whenever the repository is on a cifs mount. Instead of writing the signature data, null bytes are written in its place. Furthermore, ffmpeg and mkvmerge are now intermittently writing corrupt files to cifs mounts. No error is reported by the applications or the kernel when it happens. In the case of flatpak, the problem isn't revealed until something tries to use the repository and finds signatures full of null bytes. (Of course, this means the affected repositories have been rendered useless.) In the case of ffmpeg and mkvmerge, the problem isn't revealed until someone plays the video file and reaches a corrupt section. A kernel bisect reveals this: 3ee1a1fc39819906f04d6c62c180e760cd3a689d is the first bad commit commit 3ee1a1fc39819906f04d6c62c180e760cd3a689d Author: David Howells <dhowells(a)redhat.com> Date: Fri Oct 6 18:29:59 2023 +0100 cifs: Cut over to using netfslib I was unable to determine whether 6.11.0-rc4 fixes it, due to another cifs bug in that version (which I hope to report soon). An strace of flatpak (which uses libostree) shows it generating correct signatures internally, but behaving differently on cifs vs. ext4 when working with memory-mapped temp files, in which the signatures are stored before being written to their final outputs. Here's where I reported my initial findings to those projects: https://github.com/flatpak/flatpak/issues/5911 https://github.com/ostreedev/ostree/issues/3288 Debian Testing and Unstable kernels (6.10.4-1 and 6.10.6-1) are affected: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1079394 The following reproducer script consistently triggers the problem for me. Run it with two arguments: a path on a cifs mount where an ostree repo should be created, and a GPG key ID with which to sign a commit. #!/bin/sh set -e if [ "$#" -lt 2 ] || [ "$1" = "-h" ] ; then echo "usage: $(basename "$0") <repo-dir> <gpg-key-id>" exit 2 fi repo=$1 keyid=$2 src="./foo" echo "creating ostree repo at $repo" ostree init --repo="$repo" echo "creating source file tree at $src" mkdir -p "$src" echo hi > "$src"/hello ostree commit --repo="$repo" --branch=foo --gpg-sign="$keyid" "$src" if ostree show --repo="$repo" foo; then echo --- echo success! else echo --- ostree show --repo="$repo" --print-detached-metadata-key=ostree.gpgsigs foo echo failure! echo look for null bytes in the above commit signature fi

I found a work around for this problem. Remove the six minmax patches introduced with kernel 5.15.164: minmax: allow comparisons of 'int' against 'unsigned char/short' minmax: allow min()/max()/clamp() if the arguments have the same minmax: clamp more efficiently by avoiding extra comparison minmax: fix header inclusions minmax: relax check to allow comparison between unsigned arguments minmax: sanity check constant bounds when clamping Can these 6 patches be removed or fixed?

Tagging tail pages can cause imbalanced "calls" counters, since only head pages are untagged by pgalloc_tag_sub() and reference counts on tail pages are leaked, e.g., # echo 2048kB >/sys/kernel/mm/hugepages/hugepages-1048576kB/demote_size # echo 700 >/sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages # time echo 700 >/sys/kernel/mm/hugepages/hugepages-1048576kB/demote # grep alloc_gigantic_folio /proc/allocinfo Before this patch: 0 549427200 mm/hugetlb.c:1549 func:alloc_gigantic_folio real 0m2.057s user 0m0.000s sys 0m2.051s After this patch: 0 0 mm/hugetlb.c:1549 func:alloc_gigantic_folio real 0m1.711s user 0m0.000s sys 0m1.704s Not tagging tail pages also improves the splitting time, e.g., by about 15% when demoting 1GB hugeTLB folios to 2MB ones, as shown above.

[PATCH v2 3/3] usb: roles: Fix a false positive recursive locking complaint

by Bart Van Assche

Suppress the following lockdep complaint by giving each sw->lock a unique lockdep key instead of using the same lockdep key for all sw->lock instances: INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe you didn't initialize this object before use? turning off the locking correctness validator.

[for-linus][PATCH 2/2] tracing/timerlat: Add interface_lock around clearing of kthread in stop_kthread()

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> The timerlat interface will get and put the task that is part of the "kthread" field of the osn_var to keep it around until all references are released. But here's a race in the "stop_kthread()" code that will call put_task_struct() on the kthread if it is not a kernel thread. This can race with the releasing of the references to that task struct and the put_task_struct() can be called twice when it should have been called just once. Take the interface_lock() in stop_kthread() to synchronize this change. But to do so, the function stop_per_cpu_kthreads() needs to change the loop from for_each_online_cpu() to for_each_possible_cpu() and remove the cpu_read_lock(), as the interface_lock can not be taken while the cpu locks are held. The only side effect of this change is that it may do some extra work, as the per_cpu variables of the offline CPUs would not be set anyway, and would simply be skipped in the loop. Remove unneeded "return;" in stop_kthread().
