A prior trace point shows the allocation was an exact size match and that a length greater than MAXEXTLEN was asked for: xfs_alloc_size_done: agno 1 agbno 8 minlen 2097152 maxlen 2097152 ^^^^^^^ ^^^^^^^ We don't see this problem with extent size hints through the IO path because we can't do single IOs large enough to trigger MAXEXTLEN allocation. fallocate(), OTOH, is not limited in it's allocation sizes and so needs help here. The issue is that the extent size hint alignment is rounding up the extent size past MAXEXTLEN, because xfs_bmapi_write() is not taking into account extent size hints when calculating the maximum extent length to allocate. xfs_bmapi_reserve_delalloc() is already doing this, but direct extent allocation is not. Unfortunately, the calculation in xfs_bmapi_reserve_delalloc() is wrong, and it works only because delayed allocation extents are not limited in size to MAXEXTLEN in the in-core extent tree. hence this calculation does not work for direct allocation, and the delalloc code needs fixing. This may, in fact be the underlying bug that occassionally causes transaction overruns in delayed allocation extent conversion, so now we know it's wrong we should fix it, too. Many thanks to Brian Foster for finding this problem during review of this patch. Hence the fix, after much code reading, is to allow xfs_bmap_extsize_align() to align partial extents when full alignment would extend the alignment past MAXEXTLEN. We can safely do this because all callers have higher layer allocation loops that already handle short allocations, and so will simply run another allocation to cover the remainder of the requested allocation range that we ignored during alignment. The advantage of this approach is that it also removes the need for callers to do anything other than limit their requests to MAXEXTLEN - they don't really need to be aware of extent size hints at all.

xfs_attr3_leaf_remove() removes an attribute from an attr leaf block. If the attribute nameval data happens to be at the start of the nameval region, a new start offset (firstused) for the region is calculated (since the region grows from the tail of the block to the start). Once the new firstused is calculated, it is checked for zero in an apparent overflow check. Now that the in-core firstused is 32-bit, overflow is not possible and this check can be removed. Since the purpose for this check is not documented and appears to exist since the port to Linux, be conservative and replace it with an assert.

The on-disk xfs_attr3_leaf_hdr structure firstused field is 16-bit and subject to overflow when fs block size is 64k. The field is typically initialized to block size when an attr leaf block is initialized. This problem is demonstrated by assert failures when running xfstests generic/117 on an fs with 64k blocks. To support the existing attr leaf block algorithms for insertion, rebalance and entry movement, increase the size of the in-core firstused field to 32-bit and handle the potential overflow on conversion to/from the on-disk structure. If the overflow condition occurs, set a special value in the firstused field that is translated back on header read. The special value is only required in the case of an empty 64k attr block. A value of zero is used because firstused is initialized to the block size and grows backwards from there. Furthermore, the attribute block header occupies the first bytes of the block. Thus, a value of zero has no other legitimate meaning for this structure. Two new conversion helpers are created to manage the conversion of firstused to and from disk.

If the computed block number is not the starting block of the extent, split the extent such that the block number is the starting block of the extent. 4) Shift all the extents which are lying bewteen [offset, last allocated extent] towards right by len bytes.

Test generic/224 is failing with a corruption being detected on one of Michael's test boxes. Debug that Michael added is indicating that the minleft trimming is resulting in an underflow: ..... before fixup: rlen 1 args->len 0 after xfs_alloc_fix_len : rlen 1 args->len 1 before goto out_nominleft: rlen 1 args->len 0 before fixup: rlen 1 args->len 0 after xfs_alloc_fix_len : rlen 1 args->len 1 after fixup: rlen 1 args->len 1 before fixup: rlen 1 args->len 0 after xfs_alloc_fix_len : rlen 1 args->len 1 after fixup: rlen 4294967295 args->len 4294967295 XFS: Assertion failed: fs_is_ok, file: fs/xfs/libxfs/xfs_alloc.c, line: 1424 The "goto out_nominleft:" indicates that we are getting close to ENOSPC in the AG, and a couple of allocations later we underflow and the corruption check fires in xfs_alloc_ag_vextent_size(). The issue is that the extent length fixups comaprisons are done with variables of xfs_extlen_t types. These are unsigned so an underflow looks like a really big value and hence is not detected as being smaller than the minimum length allowed for the extent. Hence the corruption check fires as it is noticing that the returned length is longer than the original extent length passed in. This can be easily fixed by ensuring we do the underflow test on signed values, the same way xfs_alloc_fix_len() prevents underflow. So we realise in future that these casts prevent underflows from going undetected, add comments to the code indicating this. Reported-by: NMichael L.

XFS has hand-rolled per-cpu counters for the superblock since before there was any generic implementation. The free block counter is special in that it is used for ENOSPC detection outside transaction contexts for for delayed allocation. This means that the counter needs to be accurate at zero. The current per-cpu counter code jumps through lots of hoops to ensure we never run past zero, but we don't need to make all those jumps with the generic counter implementation. The generic counter implementation allows us to pass a "batch" threshold at which the addition/subtraction to the counter value will be folded back into global value under lock. We can use this feature to reduce the batch size as we approach 0 in a very similar manner to the existing counters and their rebalance algorithm. If we use a batch size of 1 as we approach 0, then every addition and subtraction will be done against the global value and hence allow accurate detection of zero threshold crossing. Hence we can replace the handrolled, accurate-at-zero counters with generic percpu counters. Note: this removes just enough of the icsb infrastructure to compile without warnings. The rest will go in subsequent commits. Signed-off-by: NDave Chinner <dchinner@redhat.com> Reviewed-by: NBrian Foster <bfoster@redhat.com> Signed-off-by: NDave Chinner <david@fromorbit.com>

Hence we don't need any of the complexity of the hand-rolled counters and we can simply replace them with generic per-cpu counters similar to the inode counter.

XFS has hand-rolled per-cpu counters for the superblock since before there was any generic implementation. There are some warts around the use of them for the inode counter as the hand rolled counter is designed to be accurate at zero, but has no specific accurracy at any other value. This design causes problems for the maximum inode count threshold enforcement, as there is no trigger that balances the counters as they get close tothe maximum threshold. Instead of designing new triggers for balancing, just replace the handrolled per-cpu counter with a generic counter. This enables us to update the counter through the normal superblock modification funtions, but rather than do that we add a xfs_mod_icount() helper function (from Christoph Hellwig) and keep the percpu counter outside the superblock in the struct xfs_mount. This means we still need to initialise the per-cpu counter specifically when we read the superblock, and vice versa when we log/write it, but it does mean that we don't need to change any other code.

When we log changes to the superblock, we first have to write them to the on-disk buffer, and then log that. Right now we have a complex bitfield based arrangement to only write the modified field to the buffer before we log it. This used to be necessary as a performance optimisation because we logged the superblock buffer in every extent or inode allocation or freeing, and so performance was extremely important. We haven't done this for years, however, ever since the lazy superblock counters pulled the superblock logging out of the transaction commit fast path. Hence we have a bunch of complexity that is not necessary that makes writing the in-core superblock to disk much more complex than it needs to be. We only need to log the superblock now during management operations (e.g. during mount, unmount or quota control operations) so it is not a performance critical path anymore. As such, remove the complex field based logging mechanism and replace it with a simple conversion function similar to what we use for all other on-disk structures. This means we always log the entirity of the superblock, but again because we rarely modify the superblock this is not an issue for log bandwidth or CPU time. Indeed, if we do log the superblock frequently, delayed logging will minimise the impact of this overhead.

Currently when we modify sb_features2, we store the same value also in sb_bad_features2. However in most places we forget to mark field sb_bad_features2 for logging and thus it can happen that a change to it is lost. This results in an inconsistent sb_features2 and sb_bad_features2 fields e.g. after xfstests test xfs/187. Fix the problem by changing XFS_SB_FEATURES2 to actually mean both sb_features2 and sb_bad_features2 fields since this is always what we want to log. This isn't ideal because the fact that XFS_SB_FEATURES2 means two fields could cause some problem in future however the code is hopefully less error prone that it is now.

After growing a filesystem, XFS can fail to allocate inodes even though there is a large amount of space available in the filesystem for inodes. The issue is caused by a nearly full allocation group having enough free space in it to be considered for inode allocation, but not enough contiguous free space to actually allocation inodes. This situation results in successful selection of the AG for allocation, then failure of the allocation resulting in ENOSPC being reported to the caller. It is caused by two possible issues. Firstly, we only consider the lognest free extent and whether it would fit an inode chunk. If the extent is not correctly aligned, then we can't allocate an inode chunk in it regardless of the fact that it is large enough. This tends to be a permanent error until space in the AG is freed. The second issue is that we don't actually lock the AGI or AGF when we are doing these checks, and so by the time we get to actually allocating the inode chunk the space we thought we had in the AG may have been allocated. This tends to be a spurious error as it requires a race to trigger. Hence this case is ignored in this patch as the reported problem is for permanent errors. The first issue could be addressed by simply taking into account the alignment when checking the longest extent. This, however, would prevent allocation in AGs that have aligned, exact sized extents free. However, this case should be fairly rare compared to the number of allocations that occur near ENOSPC that would trigger this condition. Hence, when selecting the inode AG, take into account the inode cluster alignment when checking the lognest free extent in the AG. If we can't find any AGs with a contiguous free space large enough to be aligned, drop the alignment addition and just try for an AG that has enough contiguous free space available for an inode chunk. This won't prevent issues from occurring, but should avoid situations where other AGs have lots of free space but the selected AG can't allocate due to alignment constraints.
