xfs: merge the projid fields in struct xfs_icdinode

2019-11-13T19:13:45+00:00

There is no point in splitting the fields like this in an purely in-memory structure. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J. Wong

xfs: use a struct timespec64 for the in-core crtime

2019-11-13T19:13:45+00:00

struct xfs_icdinode is purely an in-memory data structure, so don't use a log on-disk structure for it. This simplifies the code a bit, and also reduces our include hell slightly.

xfs: remove all *_ITER_ABORT values

2019-08-30T04:22:41+00:00

Use -ECANCELED to signal "stop iterating" instead of these magical *_ITER_ABORT values, since it's duplicative. Signed-off-by: Darrick J. Wong Reviewed-by: Dave Chinner

fs: xfs: Remove KM_NOSLEEP and KM_SLEEP.

2019-08-26T19:06:22+00:00

Since no caller is using KM_NOSLEEP and no callee branches on KM_SLEEP, we can remove KM_NOSLEEP and replace KM_SLEEP with 0. Signed-off-by: Tetsuo Handa Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J. Wong

xfs: fix stack contents leakage in the v1 inumber ioctls

2019-07-29T04:12:32+00:00

Explicitly initialize the onstack structures to zero so we don't leak kernel memory into userspace when converting the in-core inumbers structure to the v1 inogrp ioctl structure. Add a comment about why we have to use memset to ensure that the padding holes in the structures are set to zero.

xfs: bump INUMBERS cursor correctly in xfs_inumbers_walk

2019-07-09T15:06:20+00:00

There's a subtle unit conversion error when we increment the INUMBERS cursor at the end of xfs_inumbers_walk. If there's an inode chunk at the very end of the AG /and/ the AG size is a perfect power of two, the startino of that last chunk (which is in units of AG inodes) will be 63 less than (1 << agino_log). If we add XFS_INODES_PER_CHUNK to the startino, we end up with a startino that's larger than (1 << agino_log) and when we convert that back to fs inode units we'll rip off that upper bit and wind up back at the start of the AG. Fix this by converting to units of fs inodes before adding XFS_INODES_PER_CHUNK so that we'll harmlessly end up pointing to the next AG. Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster

xfs: specify AG in bulk req

2019-07-04T14:52:23+00:00

Add a new xfs_bulk_ireq flag to constrain the iteration to a single AG. If the passed-in startino value is zero then we start with the first inode in the AG that the user passes in; otherwise, we iterate only within the same AG as the passed-in inode.

Introduce a new version of the in-core bulkstat structure that supports our new v5 format features. This structure also fills the gaps in the previous structure. We leave wiring up the ioctls for the next patch. Signed-off-by: Darrick J. Wong Reviewed-by: Allison Collins Reviewed-by: Brian Foster
