xfs: recalculate leaf entry pointer after compacting a dir2 block

2013-01-16T22:08:55+00:00

Dave Jones hit this assert when doing a compile on recent git, with CONFIG_XFS_DEBUG enabled: XFS: Assertion failed: (char *)dup - (char *)hdr == be16_to_cpu(*xfs_dir2_data_unused_tag_p(dup)), file: fs/xfs/xfs_dir2_data.c, line: 828 Upon further digging, the tag found by xfs_dir2_data_unused_tag_p(dup) contained "2" and not the proper offset, and I found that this value was changed after the memmoves under "Use a stale leaf for our new entry." in xfs_dir2_block_addname(), i.e. memmove(&blp[mid + 1], &blp[mid], (highstale - mid) * sizeof(*blp)); overwrote it. What has happened is that the previous call to xfs_dir2_block_compact() has rearranged things; it changes btp->count as well as the blp array. So after we make that call, we must recalculate the proper pointer to the leaf entries by making another call to xfs_dir2_block_leaf_p(). Dave provided a metadump image which led to a simple reproducer (create a particular filename in the affected directory) and this resolves the testcase as well as the bug on his live system. Thanks also to dchinner for looking at this one with me. Signed-off-by: Eric Sandeen Tested-by: Dave Jones Reviewed-by: Dave Chinner Reviewed-by: Mark Tinguely Signed-off-by: Ben Myers

xfs: remove int casts from debug dquot soft limit timer asserts

2013-01-16T22:08:40+00:00

The int casts here make it easy to trigger an assert with a large soft limit. For example, set a >4TB soft limit on an empty volume to reproduce a (0 > -x) comparison due to an overflow of d_blk_softlimit. Signed-off-by: Brian Foster Reviewed-by: Ben Myers Signed-off-by: Ben Myers

xfs: fix the multi-segment log buffer format

2013-01-16T22:08:08+00:00

Per Dave Chinner suggestion, this patch: 1) Corrects the detection of whether a multi-segment buffer is still tracking data. 2) Clears all the buffer log formats for a multi-segment buffer.

xfs: fix segment in xfs_buf_item_format_segment

2013-01-16T22:07:56+00:00

Not every segment in a multi-segment buffer is dirty in a transaction and they will not be outputted. The assert in xfs_buf_item_format_segment() that checks for the at least one chunk of data in the segment to be used is not necessary true for multi-segmented buffers.

xfs: rename bli_format to avoid confusion with bli_formats

Rename the bli_format structure to __bli_format to avoid accidently confusing them with the bli_formats pointer. Signed-off-by: Mark Tinguely Reviewed-by: Christoph Hellwig Reviewed-by: Dave Chinner Signed-off-by: Ben Myers

xfs: use b_maps[] for discontiguous buffers

2013-01-16T22:07:11+00:00

Commits starting at 77c1a08 introduced a multiple segment support to xfs_buf. xfs_trans_buf_item_match() could not find a multi-segment buffer in the transaction because it was looking at the single segment block number rather than the multi-segment b_maps[0].bm.bn. This results on a recursive buffer lock that can never be satisfied. This patch: 1) Changed the remaining b_map accesses to be b_maps[0] accesses. 2) Renames the single segment b_map structure to __b_map to avoid future confusion.
