f4ce24f | Theodore Ts'o | 07 May 2023, 01:04:01 UTC | ext4: fix deadlock when converting an inline directory in nojournal mode In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock by calling ext4_handle_dirty_dirblock() when it already has taken the directory lock. There is a similar self-deadlock in ext4_incvert_inline_data_nolock() for data files which we'll fix at the same time. A simple reproducer demonstrating the problem: mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64 mount -t ext4 -o dirsync /dev/vdc /vdc cd /vdc mkdir file0 cd file0 touch file0 touch file1 attr -s BurnSpaceInEA -V abcde . touch supercalifragilisticexpialidocious Cc: stable@kernel.org Link: https://lore.kernel.org/r/20230507021608.1290720-1-tytso@mit.edu Reported-by: syzbot+91dccab7c64e2850a4e5@syzkaller.appspotmail.com Link: https://syzkaller.appspot.com/bug?id=ba84cc80a9491d65416bc7877e1650c87530fe8a Signed-off-by: Theodore Ts'o <tytso@mit.edu> | 13 May 2023, 22:05:05 UTC |
4c0b481 | Theodore Ts'o | 06 May 2023, 02:20:29 UTC | ext4: improve error recovery code paths in __ext4_remount() If there are failures while changing the mount options in __ext4_remount(), we need to restore the old mount options. This commit fixes two problem. The first is there is a chance that we will free the old quota file names before a potential failure leading to a use-after-free. The second problem addressed in this commit is if there is a failed read/write to read-only transition, if the quota has already been suspended, we need to renable quota handling.

However, with the addition of support of encrypted, casefolded file names, that function can most certainly fail today. So make sure the callers of ext4_dirhash() properly check for failures, and reflect the errors back up to their callers.

fa83c34 | Baokun Li | 05 May 2023, 13:24:29 UTC | ext4: check iomap type only if ext4_iomap_begin() does not fail When ext4_iomap_overwrite_begin() calls ext4_iomap_begin() map blocks may fail for some reason (e.g. memory allocation failure, bare disk write), and later because "iomap->type ! = IOMAP_MAPPED" triggers WARN_ON(). When ext4 iomap_begin() returns an error, it is normal that the type of iomap->type may not match the expectation.

b87c7cd | Theodore Ts'o | 30 April 2023, 07:04:13 UTC | ext4: fix invalid free tracking in ext4_xattr_move_to_block() In ext4_xattr_move_to_block(), the value of the extended attribute which we need to move to an external block may be allocated by kvmalloc() if the value is stored in an external inode. So at the end of the function the code tried to check if this was the case by testing entry->e_value_inum. However, at this point, the pointer to the xattr entry is no longer valid, because it was removed from the original location where it had been stored. So we could end up calling kvfree() on a pointer which was not allocated by kvmalloc(); or we could also potentially leak memory by not freeing the buffer when it should be freed. Fix this by storing whether it should be freed in a separate variable.

5354b2a | Theodore Ts'o | 29 April 2023, 04:06:28 UTC | ext4: allow ext4_get_group_info() to fail Previously, ext4_get_group_info() would treat an invalid group number as BUG(), since in theory it should never happen. However, if a malicious attaker (or fuzzer) modifies the superblock via the block device while it is the file system is mounted, it is possible for s_first_data_block to get set to a very large number. In that case, when calculating the block group of some block number (such as the starting block of a preallocation region), could result in an underflow and very large block group number. Then the BUG_ON check in ext4_get_group_info() would fire, resutling in a denial of service attack that can be triggered by root or someone with write access to the block device. For a quality of implementation perspective, it's best that even if the system administrator does something that they shouldn't, that it will not trigger a BUG. So instead of BUG'ing, ext4_get_group_info() will call ext4_error and return NULL. We also add fallback code in all of the callers of ext4_get_group_info() that it might NULL. Also, since ext4_get_group_info() was already borderline to be an inline function, un-inline it. The results in a next reduction of the compiled text size of ext4 by roughly 2k.

So roll this boulder up the hill one more time by re-running ./scripts/parse-maintainers.pl --order on it. This file ends up being fairly painful for merge conflicts even normally, since unlike almost all other kernel files it's one of those "everybody touches the same thing", and re-ordering all entries is only going to make that worse.

504a10d | Bob Peterson | 28 April 2023, 16:07:46 UTC | gfs2: Don't deref jdesc in evict On corrupt gfs2 file systems the evict code can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. The sequence of events is: init_journal() ... fail_jindex: gfs2_jindex_free(sdp); <------frees journals, sets jdesc = NULL if (gfs2_holder_initialized(&ji_gh)) gfs2_glock_dq_uninit(&ji_gh); fail: iput(sdp->sd_jindex); <--references jdesc in evict_linked_inode evict() gfs2_evict_inode() evict_linked_inode() ret = gfs2_trans_begin(sdp, 0, sdp->sd_jdesc->jd_blocks); <------references the now freed/zeroed sd_jdesc pointer. The call to gfs2_trans_begin is done because the truncate_inode_pages call can cause gfs2 events that require a transaction, such as removing journaled data (jdata) blocks from the journal. This patch fixes the problem by adding a check for sdp->sd_jdesc to function gfs2_evict_inode. In theory, this should only happen to corrupt gfs2 file systems, when gfs2 detects the problem, reports it, then tries to evict all the system inodes it has read in up to that point.

2da5bff | Vitaly Prosyak | 10 May 2023, 13:51:11 UTC | drm/sched: Check scheduler work queue before calling timeout handling During an IGT GPU reset test we see again oops despite of commit 0c8c901aaaebc9 (drm/sched: Check scheduler ready before calling timeout handling). It uses ready condition whether to call drm_sched_fault which unwind the TDR leads to GPU reset. However it looks the ready condition is overloaded with other meanings, for example, for the following stack is related GPU reset : 0 gfx_v9_0_cp_gfx_start 1 gfx_v9_0_cp_gfx_resume 2 gfx_v9_0_cp_resume 3 gfx_v9_0_hw_init 4 gfx_v9_0_resume 5 amdgpu_device_ip_resume_phase2 does the following: /* start the ring */ gfx_v9_0_cp_gfx_start(adev); ring->sched.ready = true; The same approach is for other ASICs as well : gfx_v8_0_cp_gfx_resume gfx_v10_0_kiq_resume, etc... As a result, our GPU reset test causes GPU fault which calls unconditionally gfx_v9_0_fault and then drm_sched_fault. However now it depends on whether the interrupt service routine drm_sched_fault is executed after gfx_v9_0_cp_gfx_start is completed which sets the ready field of the scheduler to true even for uninitialized schedulers and causes oops vs no fault or when ISR drm_sched_fault is completed prior gfx_v9_0_cp_gfx_start and NULL pointer dereference does not occur. Use the field timeout_wq to prevent oops for uninitialized schedulers. The field could be initialized by the work queue of resetting the domain. v1: Corrections to commit message (Luben) Fixes: 11b3b9f461c5c4 ("drm/sched: Check scheduler ready before calling timeout handling") Signed-off-by: Vitaly Prosyak <vitaly.prosyak@amd.com> Link: https://lore.kernel.org/r/20230510135111.58631-1-vitaly.prosyak@amd.com Reviewed-by: Luben Tuikov <luben.tuikov@amd.com> Signed-off-by: Luben Tuikov <luben.tuikov@amd.com> | 10 May 2023, 14:28:01 UTC |
1d6a4fc | Qu Wenruo | 28 April 2023, 06:13:05 UTC | btrfs: make clear_cache mount option to rebuild FST without disabling it Previously clear_cache mount option would simply disable free-space-tree feature temporarily then re-enable it to rebuild the whole free space tree. But this is problematic for block-group-tree feature, as we have an artificial dependency on free-space-tree feature. If we go the existing method, after clearing the free-space-tree feature, we would flip the filesystem to read-only mode, as we detect a super block write with block-group-tree but no free-space-tree feature. This patch would change the behavior by properly rebuilding the free space tree without disabling this feature, thus allowing clear_cache mount option to work with block group tree. Now we can mount a filesystem with block-group-tree feature and clear_mount option: $ mkfs.btrfs -O block-group-tree /dev/test/scratch1 -f $ sudo mount /dev/test/scratch1 /mnt/btrfs -o clear_cache $ sudo dmesg -t | head -n 5 BTRFS info (device dm-1): force clearing of disk cache BTRFS info (device dm-1): using free space tree BTRFS info (device dm-1): auto enabling async discard BTRFS info (device dm-1): rebuilding free space tree BTRFS info (device dm-1): checking UUID tree CC: stable@vger.kernel.org # 6.1+ Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> | 10 May 2023, 12:51:27 UTC |
