Lukas Czerner	0d94230343	fs: record I_DIRTY_TIME even if inode already has I_DIRTY_INODE ... commit cbfecb927f429a6fa613d74b998496bd71e4438a upstream. Currently the I_DIRTY_TIME will never get set if the inode already has I_DIRTY_INODE with assumption that it supersedes I_DIRTY_TIME. That's true, however ext4 will only update the on-disk inode in ->dirty_inode(), not on actual writeback. As a result if the inode already has I_DIRTY_INODE state by the time we get to __mark_inode_dirty() only with I_DIRTY_TIME, the time was already filled into on-disk inode and will not get updated until the next I_DIRTY_INODE update, which might never come if we crash or get a power failure. The problem can be reproduced on ext4 by running xfstest generic/622 with -o iversion mount option. Fix it by allowing I_DIRTY_TIME to be set even if the inode already has I_DIRTY_INODE. Also make sure that the case is properly handled in writeback_single_inode() as well. Additionally changes in xfs_fs_dirty_inode() was made to accommodate for I_DIRTY_TIME in flag. Thanks Jan Kara for suggestions on how to make this work properly.

Dave Chinner	9ec5a534d7	xfs: validate inode fork size against fork format ... [ Upstream commit 1eb70f54c445fcbb25817841e774adb3d912f3e8 ] xfs_repair catches fork size/format mismatches, but the in-kernel verifier doesn't, leading to null pointer failures when attempting to perform operations on the fork. This can occur in the xfs_dir_is_empty() where the in-memory fork format does not match the size and so the fork data pointer is accessed incorrectly. Note: this causes new failures in xfs/348 which is testing mode vs ftype mismatches. We now detect a regular file that has been changed to a directory or symlink mode as being corrupt because the data fork is for a symlink or directory should be in local form when there are only 3 bytes of data in the data fork. Hence the inode verify for the regular file now fires w/ -EFSCORRUPTED because the inode fork format does not match the format the corrupted mode says it should be in.

Dave Chinner	9e7b231687	xfs: reorder iunlink remove operation in xfs_ifree ... [ Upstream commit 9a5280b312e2e7898b6397b2ca3cfd03f67d7be1 ] The O_TMPFILE creation implementation creates a specific order of operations for inode allocation/freeing and unlinked list modification. Currently both are serialised by the AGI, so the order doesn't strictly matter as long as the are both in the same transaction. However, if we want to move the unlinked list insertions largely out from under the AGI lock, then we have to be concerned about the order in which we do unlinked list modification operations. O_TMPFILE creation tells us this order is inode allocation/free, then unlinked list modification. Change xfs_ifree() to use this same ordering on unlinked list removal. This way we always guarantee that when we enter the iunlinked list removal code from this path, we already have the AGI locked and we don't have to worry about lock nesting AGI reads inside unlink list locks because it's already locked and attached to the transaction. We can do this safely as the inode freeing and unlinked list removal are done in the same transaction and hence are atomic operations with respect to log recovery.

This is enough to make kvmalloc mad, but isn't large enough to trip the validation functions. In other words, I'm fussing with checks that were **already sufficient** because that's easier than dealing with 644 internal bug reports. Yes, that's right, six hundred and forty-four.

Eric Sandeen	1350a4cdfb	xfs: revert "xfs: actually bump warning counts when we send warnings" ... [ Upstream commit bc37e4fb5cac2925b2e286b1f1d4fc2b519f7d92 ] This reverts commit 4b8628d57b. XFS quota has had the concept of a "quota warning limit" since the earliest Irix implementation, but a mechanism for incrementing the warning counter was never implemented, as documented in the xfs_quota(8) man page. We do know from the historical archive that it was never incremented at runtime during quota reservation operations. With this commit, the warning counter quickly increments for every allocation attempt after the user has crossed a quote soft limit threshold, and this in turn transitions the user to hard quota failures, rendering soft quota thresholds and timers useless. This was reported as a regression by users. Because the intended behavior of this warning counter has never been understood or documented, and the result of this change is a regression in soft quota functionality, revert this commit to make soft quota limits and timers operable again.

Brian Foster	12689d950d	xfs: fix soft lockup via spinning in filestream ag selection loop ... [ Upstream commit f650df7171b882dca737ddbbeb414100b31f16af ] The filestream AG selection loop uses pagf data to aid in AG selection, which depends on pagf initialization. If the in-core structure is not initialized, the caller invokes the AGF read path to do so and carries on. If another task enters the loop and finds a pagf init already in progress, the AGF read returns -EAGAIN and the task continues the loop. This does not increment the current ag index, however, which means the task spins on the current AGF buffer until unlocked. If the AGF read I/O submitted by the initial task happens to be delayed for whatever reason, this results in soft lockup warnings via the spinning task. This is reproduced by xfs/170. To avoid this problem, fix the AGF trylock failure path to properly iterate to the next AG. If a task iterates all AGs without making progress, the trylock behavior is dropped in favor of blocking locks and thus a soft lockup is no longer possible.

[ Upstream commit 82be38bcf8a2e056b4c99ce79a3827fa743df6ec ] Due to cycling of m_sb_lock, it's possible for multiple callers of xfs_reserve_blocks to race at changing the pool size, subtracting blocks from fdblocks, and actually putting it in the pool. The result of all this is that we can overfill the reserve pool to hilarious levels. xfs_mod_fdblocks, when called with a positive value, already knows how to take freed blocks and either fill the reserve until it's full, or put them in fdblocks. Use that instead of setting m_resblks_avail directly. Signed-off-by: Darrick J.

Darrick J. Wong	130b5965da	xfs: reserve quota for target dir expansion when renaming files ... [ Upstream commit 41667260bc84db4dfe566e3f6ab6da5293d60d8d ] XFS does not reserve quota for directory expansion when renaming children into a directory. This means that we don't reject the expansion with EDQUOT when we're at or near a hard limit, which means that unprivileged userspace can use rename() to exceed quota. Rename operations don't always expand the target directory, and we allow a rename to proceed with no space reservation if we don't need to add a block to the target directory to handle the addition. Moreover, the unlink operation on the source directory generally does not expand the directory (you'd have to free a block and then cause a btree split) and it's probably of little consequence to leave the corner case that renaming a file out of a directory can increase its size. As with link and unlink, there is a further bug in that we do not trigger the blockgc workers to try to clear space when we're out of quota. Because rename is its own special tricky animal, we'll patch xfs_rename directly to reserve quota to the rename transaction. We'll leave cleaning up the rest of xfs_rename for the metadata directory tree patchset. Signed-off-by: Darrick J.

[ Upstream commit 871b9316e7a778ff97bdc34fdb2f2977f616651d ] XFS does not reserve quota for directory expansion when linking or unlinking children from a directory. This means that we don't reject the expansion with EDQUOT when we're at or near a hard limit, which means that unprivileged userspace can use link()/unlink() to exceed quota.

Unlink operations generally do not expand the directory (you'd have to free a block and then cause a btree split) and we can defer the directory block freeing if there is no space reservation. Moreover, there is a further bug in that we do not trigger the blockgc workers to try to clear space when we're out of quota. To fix both cases, create a new xfs_trans_alloc_dir function that allocates the transaction, locks and joins the inodes, and reserves quota for the directory. If there isn't sufficient space or quota, we'll switch the caller to reservationless mode. This should prevent quota usage overruns with the least restriction in functionality.

Brian Foster	139e6fc6e7	xfs: flush inodegc workqueue tasks before cancel ... [ Upstream commit 6191cf3ad59fda5901160633fef8e41b064a5246 ] The xfs_inodegc_stop() helper performs a high level flush of pending work on the percpu queues and then runs a cancel_work_sync() on each of the percpu work tasks to ensure all work has completed before returning. While cancel_work_sync() waits for wq tasks to complete, it does not guarantee work tasks have started. This means that the _stop() helper can queue and instantly cancel a wq task without having completed the associated work. This can be observed by tracepoint inspection of a simple "rm -f <file>; fsfreeze -f <mnt>" test: xfs_destroy_inode: ... ino 0x83 ... xfs_inode_set_need_inactive: ... ino 0x83 ... xfs_inodegc_stop: ... ... xfs_inodegc_start: ... xfs_inodegc_worker: ... xfs_inode_inactivating: ... ino 0x83 ... The first few lines show that the inode is removed and need inactive state set, but the inactivation work has not completed before the inodegc mechanism stops. The inactivation doesn't actually occur until the fs is unfrozen and the gc mechanism starts back up. Note that this test requires fsfreeze to reproduce because xfs_freeze indirectly invokes xfs_fs_statfs(), which calls xfs_inodegc_flush(). When this occurs, the workqueue try_to_grab_pending() logic first tries to steal the pending bit, which does not succeed because the bit has been set by queue_work_on(). Subsequently, it checks for association of a pool workqueue from the work item under the pool lock. This association is set at the point a work item is queued and cleared when dequeued for processing. If the association exists, the work item is removed from the queue and cancel_work_sync() returns true. If the pwq association is cleared, the remove attempt assumes the task is busy and retries (eventually returning false to the caller after waiting for the work task to complete). To avoid this race, we can flush each work item explicitly before cancel. However, since the _queue_all() already schedules each underlying work item, the workqueue level helpers are sufficient to achieve the same ordering effect. E.g., the inodegc enabled flag prevents scheduling any further work in the _stop() case. Use the drain_workqueue() helper in this particular case to make the intent a bit more self explanatory.

Brian Foster	1da0b50ea0	xfs: fix perag reference leak on iteration race with growfs ... [ Upstream commit 892a666fafa19ab04b5e948f6c92f98f1dafb489 ] The for_each_perag*() set of macros are hacky in that some (i.e. those based on sb_agcount) rely on the assumption that perag iteration terminates naturally with a NULL perag at the specified end_agno. Others allow for the final AG to have a valid perag and require the calling function to clean up any potential leftover xfs_perag reference on termination of the loop. Aside from providing a subtly inconsistent interface, the former variant is racy with growfs because growfs can create discoverable post-eofs perags before the final superblock update that completes the grow operation and increases sb_agcount. This leads to the following assert failure (reproduced by xfs/104) in the perag free path during unmount: XFS: Assertion failed: atomic_read(&pag->pag_ref) == 0, file: fs/xfs/libxfs/xfs_ag.c, line: 195 This occurs because one of the many for_each_perag() loops in the code that is expected to terminate with a NULL pag (and thus has no post-loop xfs_perag_put() check) raced with a growfs and found a non-NULL post-EOFS perag, but terminated naturally based on the end_agno check without releasing the post-EOFS perag. Rework the iteration logic to lift the agno check from the main for loop conditional to the iteration helper function. The for loop now purely terminates on a NULL pag and xfs_perag_next() avoids taking a reference to any perag beyond end_agno in the first place.

Brian Foster	768bfde1cf	xfs: terminate perag iteration reliably on agcount ... [ Upstream commit 8ed004eb9d07a5d6114db3e97a166707c186262d ] The for_each_perag_from() iteration macro relies on sb_agcount to process every perag currently within EOFS from a given starting point. It's perfectly valid to have perag structures beyond sb_agcount, however, such as if a growfs is in progress. If a perag loop happens to race with growfs in this manner, it will actually attempt to process the post-EOFS perag where ->pag_agno == sb_agcount. This is reproduced by xfs/104 and manifests as the following assert failure in superblock write verifier context: XFS: Assertion failed: agno < mp->m_sb.sb_agcount, file: fs/xfs/libxfs/xfs_types.c, line: 22 Update the corresponding macro to only process perags that are within the current sb_agcount.

[ Upstream commit 919edbadebe17a67193533f531c2920c03e40fa4 ] Jan Kara reported a performance regression in dbench that he bisected down to commit bad77c375e ("xfs: CIL checkpoint flushes caches unconditionally"). Whilst developing the journal flush/fua optimisations this cache was part of, it appeared to made a significant difference to performance. However, now that this patchset has settled and all the correctness issues fixed, there does not appear to be any significant performance benefit to asynchronous cache flushes. In fact, the opposite is true on some storage types and workloads, where additional cache flushes that can occur from fsync heavy workloads have measurable and significant impact on overall throughput. Local dbench testing shows little difference on dbench runs with sync vs async cache flushes on either fast or slow SSD storage, and no difference in streaming concurrent async transaction workloads like fs-mark.

Dave Chinner	d4dab8b405	xfs: run callbacks before waking waiters in xlog_state_shutdown_callbacks ... [ Upstream commit cd6f79d1fb324968a3bae92f82eeb7d28ca1fd22 ] Brian reported a null pointer dereference failure during unmount in xfs/006. He tracked the problem down to the AIL being torn down before a log shutdown had completed and removed all the items from the AIL. The failure occurred in this path while unmount was proceeding in another task: xfs_trans_ail_delete+0x102/0x130 [xfs] xfs_buf_item_done+0x22/0x30 [xfs] xfs_buf_ioend+0x73/0x4d0 [xfs] xfs_trans_committed_bulk+0x17e/0x2f0 [xfs] xlog_cil_committed+0x2a9/0x300 [xfs] xlog_cil_process_committed+0x69/0x80 [xfs] xlog_state_shutdown_callbacks+0xce/0xf0 [xfs] xlog_force_shutdown+0xdf/0x150 [xfs] xfs_do_force_shutdown+0x5f/0x150 [xfs] xlog_ioend_work+0x71/0x80 [xfs] process_one_work+0x1c5/0x390 worker_thread+0x30/0x350 kthread+0xd7/0x100 ret_from_fork+0x1f/0x30 This is processing an EIO error to a log write, and it's triggering a force shutdown. This causes the log to be shut down, and then it is running attached iclog callbacks from the shutdown context. That means the fs and log has already been marked as xfs_is_shutdown/xlog_is_shutdown and so high level code will abort (e.g. xfs_trans_commit(), xfs_log_force(), etc) with an error because of shutdown. The umount would have been blocked waiting for a log force completion inside xfs_log_cover() -> xfs_sync_sb(). The first thing for this situation to occur is for xfs_sync_sb() to exit without waiting for the iclog buffer to be comitted to disk. The above trace is the completion routine for the iclog buffer, and it is shutting down the filesystem. xlog_state_shutdown_callbacks() does this: { struct xlog_in_core *iclog; LIST_HEAD(cb_list); spin_lock(&log->l_icloglock); iclog = log->l_iclog; do { if (atomic_read(&iclog->ic_refcnt)) { /* Reference holder will re-run iclog callbacks. */ continue; } list_splice_init(&iclog->ic_callbacks, &cb_list); >>>>>> wake_up_all(&iclog->ic_write_wait); >>>>>> wake_up_all(&iclog->ic_force_wait); } while ((iclog = iclog->ic_next) != log->l_iclog); wake_up_all(&log->l_flush_wait); spin_unlock(&log->l_icloglock); >>>>>> xlog_cil_process_committed(&cb_list); } This wakes any thread waiting on IO completion of the iclog (in this case the umount log force) before shutdown processes all the pending callbacks. That means the xfs_sync_sb() waiting on a sync transaction in xfs_log_force() on iclog->ic_force_wait will get woken before the callbacks attached to that iclog are run. This results in xfs_sync_sb() returning an error, and so unmount unblocks and continues to run whilst the log shutdown is still in progress. Normally this is just fine because the force waiter has nothing to do with AIL operations. But in the case of this unmount path, the log force waiter goes on to tear down the AIL because the log is now shut down and so nothing ever blocks it again from the wait point in xfs_log_cover(). Hence it's a race to see who gets to the AIL first - the unmount code or xlog_cil_process_committed() killing the superblock buffer. To fix this, we just have to change the order of processing in xlog_state_shutdown_callbacks() to run the callbacks before it wakes any task waiting on completion of the iclog.

Darrick J. Wong	88beb994ea	xfs: don't include bnobt blocks when reserving free block pool ... [ Upstream commit c8c568259772751a14e969b7230990508de73d9d ] xfs_reserve_blocks controls the size of the user-visible free space reserve pool. Given the difference between the current and requested pool sizes, it will try to reserve free space from fdblocks. However, the amount requested from fdblocks is also constrained by the amount of space that we think xfs_mod_fdblocks will give us. If we forget to subtract m_allocbt_blks before calling xfs_mod_fdblocks, it will will return ENOSPC and we'll hang the kernel at mount due to the infinite loop. In commit fd43cf600c, we decided that xfs_mod_fdblocks should not hand out the "free space" used by the free space btrees, because some portion of the free space btrees hold in reserve space for future btree expansion. Unfortunately, xfs_reserve_blocks' estimation of the number of blocks that it could request from xfs_mod_fdblocks was not updated to include m_allocbt_blks, so if space is extremely low, the caller hangs. Fix this by creating a function to estimate the number of blocks that can be reserved from fdblocks, which needs to exclude the set-aside and m_allocbt_blks. Found by running xfs/306 (which formats a single-AG 20MB filesystem) with an fstests configuration that specifies a 1k blocksize and a specially crafted log size that will consume 7/8 of the space (17920 blocks, specifically) in that AG.

Darrick J. Wong	ea22fcd032	xfs: only run COW extent recovery when there are no live extents ... [ Upstream commit 7993f1a431bc5271369d359941485a9340658ac3 ] As part of multiple customer escalations due to file data corruption after copy on write operations, I wrote some fstests that use fsstress to hammer on COW to shake things loose. Regrettably, I caught some filesystem shutdowns due to incorrect rmap operations with the following loop: mount <filesystem> # (0) fsstress <run only readonly ops> & # (1) while true; do fsstress <run all ops> mount -o remount,ro # (2) fsstress <run only readonly ops> mount -o remount,rw # (3) done When (2) happens, notice that (1) is still running. xfs_remount_ro will call xfs_blockgc_stop to walk the inode cache to free all the COW extents, but the blockgc mechanism races with (1)'s reader threads to take IOLOCKs and loses, which means that it doesn't clean them all out. Call such a file (A). When (3) happens, xfs_remount_rw calls xfs_reflink_recover_cow, which walks the ondisk refcount btree and frees any COW extent that it finds. This function does not check the inode cache, which means that incore COW forks of inode (A) is now inconsistent with the ondisk metadata. If one of those former COW extents are allocated and mapped into another file (B) and someone triggers a COW to the stale reservation in (A), A's dirty data will be written into (B) and once that's done, those blocks will be transferred to (A)'s data fork without bumping the refcount. The results are catastrophic -- file (B) and the refcount btree are now corrupt. In the first patch, we fixed the race condition in (2) so that (A) will always flush the COW fork. In this second patch, we move the _recover_cow call to the initial mount call in (0) for safety. As mentioned previously, xfs_reflink_recover_cow walks the refcount btree looking for COW staging extents, and frees them. This was intended to be run at mount time (when we know there are no live inodes) to clean up any leftover staging events that may have been left behind during an unclean shutdown. As a time "optimization" for readonly mounts, we deferred this to the ro->rw transition, not realizing that any failure to clean all COW forks during a rw->ro transition would result in catastrophic corruption. Therefore, remove this optimization and only run the recovery routine when we're guaranteed not to have any COW staging extents anywhere, which means we always run this at mount time. While we're at it, move the callsite to xfs_log_mount_finish because any refcount btree expansion (however unlikely given that we're removing records from the right side of the index) must be fed by a per-AG reservation, which doesn't exist in its current location.

Christian Brauner	21c6c720be	fs: port higher-level mapping helpers ... commit 209188ce75d0d357c292f6bb81d712acdd4e7db7 upstream. Enable the mapped_fs{g,u}id() helpers to support filesystems mounted with an idmapping. Apart from core mapping helpers that use mapped_fs{g,u}id() to initialize struct inode's i_{g,u}id fields xfs is the only place that uses these low-level helpers directly. The patch only extends the helpers to be able to take the filesystem idmapping into account. Since we don't actually yet pass the filesystem's idmapping in no functional changes happen. This will happen in a final patch.

Christian Brauner	7bc23abcb4	fs: move mapping helpers ... commit a793d79ea3e041081cd7cbd8ee43d0b5e4914a2b upstream. The low-level mapping helpers were so far crammed into fs.h. They are out of place there. The fs.h header should just contain the higher-level mapping helpers that interact directly with vfs objects such as struct super_block or struct inode and not the bare mapping helpers. Similarly, only vfs and specific fs code shall interact with low-level mapping helpers. And so they won't be made accessible automatically through regular {g,u}id helpers.

Darrick J. Wong	ce6bfe5523	xfs: only bother with sync_filesystem during readonly remount ... [ Upstream commit b97cca3ba9098522e5a1c3388764ead42640c1a5 ] In commit 02b9984d64, we pushed a sync_filesystem() call from the VFS into xfs_fs_remount. The only time that we ever need to push dirty file data or metadata to disk for a remount is if we're remounting the filesystem read only, so this really could be moved to xfs_remount_ro. Once we've moved the call site, actually check the return value from sync_filesystem. Fixes: 02b9984d64 ("fs: push sync_filesystem() down to the file system's remount_fs()") Signed-off-by: Darrick J.

Darrick J. Wong	3465b16783	xfs: prevent UAF in xfs_log_item_in_current_chkpt ... [ Upstream commit f8d92a66e810acbef6ddbc0bd0cbd9b117ce8acd ] While I was running with KASAN and lockdep enabled, I stumbled upon an KASAN report about a UAF to a freed CIL checkpoint. Looking at the comment for xfs_log_item_in_current_chkpt, it seems pretty obvious to me that the original patch to xfs_defer_finish_noroll should have done something to lock the CIL to prevent it from switching the CIL contexts while the predicate runs. For upper level code that needs to know if a given log item is new enough not to need relogging, add a new wrapper that takes the CIL context lock long enough to sample the current CIL context. This is kind of racy in that the CIL can switch the contexts immediately after sampling, but that's ok because the consequence is that the defer ops code is a little slow to relog items. ================================================================== BUG: KASAN: use-after-free in xfs_log_item_in_current_chkpt+0x139/0x160 [xfs] Read of size 8 at addr ffff88804ea5f608 by task fsstress/527999 CPU: 1 PID: 527999 Comm: fsstress Tainted: G D 5.16.0-rc4-xfsx #rc4 Call Trace: <TASK> dump_stack_lvl+0x45/0x59 print_address_description.constprop.0+0x1f/0x140 kasan_report.cold+0x83/0xdf xfs_log_item_in_current_chkpt+0x139/0x160 xfs_defer_finish_noroll+0x3bb/0x1e30 __xfs_trans_commit+0x6c8/0xcf0 xfs_reflink_remap_extent+0x66f/0x10e0 xfs_reflink_remap_blocks+0x2dd/0xa90 xfs_file_remap_range+0x27b/0xc30 vfs_dedupe_file_range_one+0x368/0x420 vfs_dedupe_file_range+0x37c/0x5d0 do_vfs_ioctl+0x308/0x1260 __x64_sys_ioctl+0xa1/0x170 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae RIP: 0033:0x7f2c71a2950b Code: 0f 1e fa 48 8b 05 85 39 0d 00 64 c7 00 26 00 00 00 48 c7 c0 ff ff ff ff c3 66 0f 1f 44 00 00 f3 0f 1e fa b8 10 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 55 39 0d 00 f7 d8 64 89 01 48 RSP: 002b:00007ffe8c0e03c8 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00005600862a8740 RCX: 00007f2c71a2950b RDX: 00005600862a7be0 RSI: 00000000c0189436 RDI: 0000000000000004 RBP: 000000000000000b R08: 0000000000000027 R09: 0000000000000003 R10: 0000000000000000 R11: 0000000000000246 R12: 000000000000005a R13: 00005600862804a8 R14: 0000000000016000 R15: 00005600862a8a20 </TASK> Allocated by task 464064: kasan_save_stack+0x1e/0x50 __kasan_kmalloc+0x81/0xa0 kmem_alloc+0xcd/0x2c0 [xfs] xlog_cil_ctx_alloc+0x17/0x1e0 [xfs] xlog_cil_push_work+0x141/0x13d0 [xfs] process_one_work+0x7f6/0x1380 worker_thread+0x59d/0x1040 kthread+0x3b0/0x490 ret_from_fork+0x1f/0x30 Freed by task 51: kasan_save_stack+0x1e/0x50 kasan_set_track+0x21/0x30 kasan_set_free_info+0x20/0x30 __kasan_slab_free+0xed/0x130 slab_free_freelist_hook+0x7f/0x160 kfree+0xde/0x340 xlog_cil_committed+0xbfd/0xfe0 [xfs] xlog_cil_process_committed+0x103/0x1c0 [xfs] xlog_state_do_callback+0x45d/0xbd0 [xfs] xlog_ioend_work+0x116/0x1c0 [xfs] process_one_work+0x7f6/0x1380 worker_thread+0x59d/0x1040 kthread+0x3b0/0x490 ret_from_fork+0x1f/0x30 Last potentially related work creation: kasan_save_stack+0x1e/0x50 __kasan_record_aux_stack+0xb7/0xc0 insert_work+0x48/0x2e0 __queue_work+0x4e7/0xda0 queue_work_on+0x69/0x80 xlog_cil_push_now.isra.0+0x16b/0x210 [xfs] xlog_cil_force_seq+0x1b7/0x850 [xfs] xfs_log_force_seq+0x1c7/0x670 [xfs] xfs_file_fsync+0x7c1/0xa60 [xfs] __x64_sys_fsync+0x52/0x80 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae The buggy address belongs to the object at ffff88804ea5f600 which belongs to the cache kmalloc-256 of size 256 The buggy address is located 8 bytes inside of 256-byte region [ffff88804ea5f600, ffff88804ea5f700) The buggy address belongs to the page: page:ffffea00013a9780 refcount:1 mapcount:0 mapping:0000000000000000 index:0xffff88804ea5ea00 pfn:0x4ea5e head:ffffea00013a9780 order:1 compound_mapcount:0 flags: 0x4fff80000010200(slab|head|node=1|zone=1|lastcpupid=0xfff) raw: 04fff80000010200 ffffea0001245908 ffffea00011bd388 ffff888004c42b40 raw: ffff88804ea5ea00 0000000000100009 00000001ffffffff 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff88804ea5f500: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ffff88804ea5f580: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc >ffff88804ea5f600: fa fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb ^ ffff88804ea5f680: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb ffff88804ea5f700: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc ================================================================== Fixes: 4e919af782 ("xfs: periodically relog deferred intent items") Signed-off-by: Darrick J.

That is, log recovery was overwriting a buffer with newer changes on disk than was in the transaction. Tracing indicated that we were hitting the "recovery immediately" case in xfs_buf_log_recovery_lsn(), and hence it was ignoring the LSN in the buffer. The code was extracting the LSN correctly, then ignoring it because the UUID in the buffer did not match the superblock UUID. The problem arises because the UUID check uses the wrong UUID - it should be checking the sb_meta_uuid, not sb_uuid. This filesystem has sb_uuid != sb_meta_uuid (which is fine), and the buffer has the correct matching sb_meta_uuid in it, it's just the code checked it against the wrong superblock uuid. The is no corruption in the filesystem, and failing to recover the buffer due to a write verifier failure means the recovery bug did not propagate the corruption to disk. Hence there is no corruption before or after this bug has manifested, the impact is limited simply to an unmountable filesystem.... This was missed back in 2015 during an audit of incorrect sb_uuid usage that resulted in commit fcfbe2c4ef ("xfs: log recovery needs to validate against sb_meta_uuid") that fixed the magic32 buffers to validate against sb_meta_uuid instead of sb_uuid. It missed the magicda buffers.... Fixes: ce748eaa65 ("xfs: create new metadata UUID field and incompat flag") Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

Darrick J. Wong	c4f376ba8b	xfs: remove all COW fork extents when remounting readonly ... [ Upstream commit 089558bc7ba785c03815a49c89e28ad9b8de51f9 ] As part of multiple customer escalations due to file data corruption after copy on write operations, I wrote some fstests that use fsstress to hammer on COW to shake things loose. Regrettably, I caught some filesystem shutdowns due to incorrect rmap operations with the following loop: mount <filesystem> # (0) fsstress <run only readonly ops> & # (1) while true; do fsstress <run all ops> mount -o remount,ro # (2) fsstress <run only readonly ops> mount -o remount,rw # (3) done When (2) happens, notice that (1) is still running. xfs_remount_ro will call xfs_blockgc_stop to walk the inode cache to free all the COW extents, but the blockgc mechanism races with (1)'s reader threads to take IOLOCKs and loses, which means that it doesn't clean them all out. Call such a file (A). When (3) happens, xfs_remount_rw calls xfs_reflink_recover_cow, which walks the ondisk refcount btree and frees any COW extent that it finds. This function does not check the inode cache, which means that incore COW forks of inode (A) is now inconsistent with the ondisk metadata. If one of those former COW extents are allocated and mapped into another file (B) and someone triggers a COW to the stale reservation in (A), A's dirty data will be written into (B) and once that's done, those blocks will be transferred to (A)'s data fork without bumping the refcount. The results are catastrophic -- file (B) and the refcount btree are now corrupt. Solve this race by forcing the xfs_blockgc_free_space to run synchronously, which causes xfs_icwalk to return to inodes that were skipped because the blockgc code couldn't take the IOLOCK. This is safe to do here because the VFS has already prohibited new writer threads. Fixes: 10ddf64e42 ("xfs: remove leftover CoW reservations when remounting ro") Signed-off-by: Darrick J.

But xfs_attr_node_hasname will free state itself instead of caller if xfs_da3_node_lookup_int fails. Fix this bug by moving the step of free state into caller. Also, use "goto error/out" instead of returning error directly in xfs_attr_node_addname_find_attr and xfs_attr_node_removename_setup function because we should free state ourselves.

Brian Foster	0e84e17c16	xfs: punch out data fork delalloc blocks on COW writeback failure ... [ Upstream commit 5ca5916b6bc93577c360c06cb7cdf71adb9b5faf ] If writeback I/O to a COW extent fails, the COW fork blocks are punched out and the data fork blocks left alone. It is possible for COW fork blocks to overlap non-shared data fork blocks (due to cowextsz hint prealloc), however, and writeback unconditionally maps to the COW fork whenever blocks exist at the corresponding offset of the page undergoing writeback. This means it's quite possible for a COW fork extent to overlap delalloc data fork blocks, writeback to convert and map to the COW fork blocks, writeback to fail, and finally for ioend completion to cancel the COW fork blocks and leave stale data fork delalloc blocks around in the inode. The blocks are effectively stale because writeback failure also discards dirty page state. If this occurs, it is likely to trigger assert failures, free space accounting corruption and failures in unrelated file operations. For example, a subsequent reflink attempt of the affected file to a new target file will trip over the stale delalloc in the source file and fail. Several of these issues are occasionally reproduced by generic/648, but are reproducible on demand with the right sequence of operations and timely I/O error injection. To fix this problem, update the ioend failure path to also punch out underlying data fork delalloc blocks on I/O error. This is analogous to the writeback submission failure path in xfs_discard_page() where we might fail to map data fork delalloc blocks and consistent with the successful COW writeback completion path, which is responsible for unmapping from the data fork and remapping in COW fork blocks.

[ Upstream commit c30a0cbd07ecc0eec7b3cd568f7b1c7bb7913f93 ] For kmalloc() allocations SLOB prepends the blocks with a 4-byte header, and it puts the size of the allocated blocks in that header. Blocks allocated with kmem_cache_alloc() allocations do not have that header. SLOB explodes when you allocate memory with kmem_cache_alloc() and then try to free it with kfree() instead of kmem_cache_free(). SLOB will assume that there is a header when there is none, read some garbage to size variable and corrupt the adjacent objects, which eventually leads to hang or panic. Let's make XFS work with SLOB by using proper free function.

When the request succeeds, we report that done_before additional bytes were tranferred.

We'll use that to allow iomap_dio_rw to be used with page faults disabled: when a page fault occurs while submitting a request, we synchronously complete the part of the request that has already been submitted. The caller can then take care of the page fault and call iomap_dio_rw again for the rest of the request, passing in the number of bytes already tranferred.

Michel Lespinasse	7045d2d838	FROMLIST: mm: implement speculative handling in do_fault_around() ... Call the vm_ops->map_pages method within an rcu read locked section. In the speculative case, verify the mmap sequence lock at the start of the section. A match guarantees that the original vma is still valid at that time, and that the associated vma->vm_file stays valid while the vm_ops->map_pages() method is running. Do not test vmf->pmd in the speculative case - we only speculate when a page table already exists, and and this saves us from having to handle synchronization around the vmf->pmd read. Change xfs_filemap_map_pages() account for the fact that it can not block anymore, as it is now running within an rcu read lock.
