[PATCH] f2fs: Revert "f2fs: truncate blocks in batch in __complete_revoke_list()"

by Jaegeuk Kim

We should not truncate replaced blocks, and were supposed to truncate the first part as well. This reverts commit 78a99fe6254cad4be310cd84af39f6c46b668c72.

[PATCH 6.1 0/4] mptcp: Stable backports for 6.1.12

by Matthieu Baerts

Hi Greg, Sasha, Here are two MPTCP patches backports (patches 2-3/4), and one prerequisite (patch 1/4), that recently failed to apply to the 6.1 stable tree. They prevent some locking issues with MPTCP. After having cherry-picked patch 1/4 -- a simple refactoring to make a function more generic -- patch 2/4 applied without any issue. For patch 3/4, I had to resolve two simple function because two if-statements around the modified code have curly braces in v6.1, not later, see commit 976d302fb616 ("mptcp: deduplicate error paths on endpoint creation"). On top of that, patch 4/4 fixes MPTCP userspace PM selftest that has been recently broken due to a backport done in v6.1.8.

[PATCH 5.15 00/10] xfs backports for 5.15.y

by Leah Rumancik

Hello, Here is the next batch of backports for 5.15.y. These patches have already been ACK'd on the xfs mailing list. Testing included 25 runs of auto group on 12 xfs configs. No regressions were seen. I checked xfs/538 was run without issue as this test was mentioned in 56486f307100. Also, from 86d40f1e49e9, I ran ran xfs/117 with XFS compiled as a module and TEST_FS_MODULE_REOLOAD set, but I was unable to reproduce the issue. Below I've outlined which series the backports came from: series "xfs: intent whiteouts" (1): [01/10] cb512c921639613ce03f87e62c5e93ed9fe8c84d xfs: zero inode fork buffer at allocation [02/10] c230a4a85bcdbfc1a7415deec6caf04e8fca1301 xfs: fix potential log item leak series "xfs: fix random format verification issues" (2): [1/4] dc04db2aa7c9307e740d6d0e173085301c173b1a xfs: detect self referencing btree sibling pointers [2/4] 1eb70f54c445fcbb25817841e774adb3d912f3e8 -> already in 5.15.y xfs: validate inode fork size against fork format [3/4] dd0d2f9755191690541b09e6385d0f8cd8bc9d8f xfs: set XFS_FEAT_NLINK correctly [4/4] f0f5f658065a5af09126ec892e4c383540a1c77f xfs: validate v5 feature fields series "xfs: small fixes for 5.19 cycle" (3): [1/3] 5672225e8f2a872a22b0cecedba7a6644af1fb84 xfs: avoid unnecessary runtime sibling pointer endian conversions [2/3] 5b55cbc2d72632e874e50d2e36bce608e55aaaea fs: don't assert fail on perag references on teardown [2/3] 56486f307100e8fc66efa2ebd8a71941fa10bf6f xfs: assert in xfs_btree_del_cursor should take into account error series "xfs: random fixes for 5.19" (4): [1/2] 86d40f1e49e9a909d25c35ba01bea80dbcd758cb xfs: purge dquots after inode walk fails during quotacheck [2/2] a54f78def73d847cb060b18c4e4a3d1d26c9ca6d xfs: don't leak btree cursor when insrec fails after a split (1) https://lore.kernel.org/all/20220503221728.185449-1-david@fromorbit.com/ (2) https://lore.kernel.org/all/20220502082018.1076561-1-david@fromorbit.com/ (3) https://lore.kernel.org/all/20220524022158.1849458-1-david@fromorbit.com/ (4) https://lore.kernel.org/all/165337056527.993079.1232300816023906959.stgit@m… - Leah Darrick J.

[PATCH v3] s390/signal: fix endless loop in do_signal

by Sumanth Korikkar

No upstream commit exists: the problem addressed here is that 'commit 75309018a24d ("s390: add support for TIF_NOTIFY_SIGNAL")' was backported to 5.10. This commit is broken, but nobody noticed upstream, since shortly after s390 converted to generic entry with 'commit 56e62a737028 ("s390: convert to generic entry")', which implicitly fixed the problem outlined below. Thread flag is set to TIF_NOTIFY_SIGNAL for io_uring work. The io work user or syscall calls do_signal when either one of the TIF_SIGPENDING or TIF_NOTIFY_SIGNAL flag is set. However, do_signal does consider only TIF_SIGPENDING signal and ignores TIF_NOTIFY_SIGNAL condition. This means get_signal is never invoked for TIF_NOTIFY_SIGNAL and hence the flag is not cleared, which results in an endless do_signal loop. Reference: 'commit 788d0824269b ("io_uring: import 5.15-stable io_uring")' Fixes: 75309018a24d ("s390: add support for TIF_NOTIFY_SIGNAL") Cc: stable(a)vger.kernel.org # 5.10.162 Acked-by: Heiko Carstens <hca(a)linux.ibm.com> Acked-by: Sven Schnelle <svens(a)linux.ibm.com> Signed-off-by: Sumanth Korikkar <sumanthk(a)linux.ibm.com> --- v2->v3: Correct changelog. v1->v2: Add the changelog. arch/s390/kernel/signal.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/s390/kernel/signal.c b/arch/s390/kernel/signal.c index b27b6c1f058d..9e900a8977bd 100644 --- a/arch/s390/kernel/signal.c +++ b/arch/s390/kernel/signal.c @@ -472,7 +472,7 @@ void do_signal(struct pt_regs *regs) current->thread.system_call = test_pt_regs_flag(regs, PIF_SYSCALL) ? regs->int_code : 0; - if (test_thread_flag(TIF_SIGPENDING) && get_signal(&ksig)) { + if (get_signal(&ksig)) { /* Whee!

[PATCH 0/1] s390: fix endless loop in do_signal

by Sumanth Korikkar

Hi, This patch fixes the issue for s390 stable kernel starting 5.10.162. The issue was specifically seen after stable version 5.10.162: Following commits can trigger it: 1. stable commit id - 788d0824269b ("io_uring: import 5.15-stable io_uring") can trigger this problem. 2. upstream commit id - 75309018a24d ("s390: add support for TIF_NOTIFY_SIGNAL") Problem: qemu and user processes could stall when TIF_NOTIFY_SIGNAL is set from io_uring work. Affected users: The issue was first raised by the debian team, where the s390 bullseye build systems are affected. Upstream commit Id: * The attached patch has no upstream commit. However, the stable kernel 5.10.162+ uses upstream commit id - 75309018a24d ("s390: add support for TIF_NOTIFY_SIGNAL"), which would need this fix * Starting from v5.12, there are s390 generic entry commits 56e62a737028 ("s390: convert to generic entry") and its relevant fixes, which are recommended and should address these problems. Kernel version to be applied: stable kernel 5.10.162+ Thanks.

[PATCH v4] sched/psi: fix use-after-free in ep_remove_wait_queue()

by Munehisa Kamata

If a non-root cgroup gets removed when there is a thread that registered trigger and is polling on a pressure file within the cgroup, the polling waitqueue gets freed in the following path. do_rmdir cgroup_rmdir kernfs_drain_open_files cgroup_file_release cgroup_pressure_release psi_trigger_destroy However, the polling thread still has a reference to the pressure file and will access the freed waitqueue when the file is closed or upon exit. fput ep_eventpoll_release ep_free ep_remove_wait_queue remove_wait_queue This results in use-after-free as pasted below. The fundamental problem here is that cgroup_file_release() (and consequently waitqueue's lifetime) is not tied to the file's real lifetime. Using wake_up_pollfree() here might be less than ideal, but it is in line with the comment at commit 42288cb44c4b ("wait: add wake_up_pollfree()") since the waitqueue's lifetime is not tied to file's one and can be considered as another special case. While this would be fixable by somehow making cgroup_file_release() be tied to the fput(), it would require sizable refactoring at cgroups or higher layer which might be more justifiable if we identify more cases like this.

by syzbot

This bug is marked as fixed by commit: ext4: block range must be validated before use in ext4_mb_clear_bb() But I can't find it in the tested trees[1] for more than 90 days. Is it a correct commit? Please update it by replying: #syz fix: exact-commit-title Until then the bug is still considered open and new crashes with the same signature are ignored. Kernel: Android 5.10 Dashboard link: https://syzkaller.appspot.com/bug?extid=15cd994e273307bf5cfa --- [1] I expect the commit to be present in: 1. android12-5.10-lts branch of https://android.googlesource.com/kernel/common
