From ad747e3b299671e1a53db74963cc6c5f6cdb9f6d Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Wed, 6 Apr 2016 07:06:20 +1000 Subject: xfs: Don't wrap growfs AGFL indexes Commit 96f859d ("libxfs: pack the agfl header structure so XFS_AGFL_SIZE is correct") allowed the freelist to use the empty slot at the end of the freelist on 64 bit systems that was not being used due to sizeof() rounding up the structure size. This has caused versions of xfs_repair prior to 4.5.0 (which also has the fix) to report this as a corruption once the filesystem has been grown. Older kernels can also have problems (seen from a whacky container/vm management environment) mounting filesystems grown on a system with a newer kernel than the vm/container it is deployed on. To avoid this problem, change the initial free list indexes not to wrap across the end of the AGFL, hence avoiding the initialisation of agf_fllast to the last index in the AGFL. cc: # 4.4-4.5 Signed-off-by: Dave Chinner Reviewed-by: Carlos Maiolino Signed-off-by: Dave Chinner --- fs/xfs/xfs_fsops.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'fs/xfs/xfs_fsops.c') diff --git a/fs/xfs/xfs_fsops.c b/fs/xfs/xfs_fsops.c index ee3aaa0a5317..ca0d3eb44925 100644 --- a/fs/xfs/xfs_fsops.c +++ b/fs/xfs/xfs_fsops.c @@ -243,8 +243,8 @@ xfs_growfs_data_private( agf->agf_roots[XFS_BTNUM_CNTi] = cpu_to_be32(XFS_CNT_BLOCK(mp)); agf->agf_levels[XFS_BTNUM_BNOi] = cpu_to_be32(1); agf->agf_levels[XFS_BTNUM_CNTi] = cpu_to_be32(1); - agf->agf_flfirst = 0; - agf->agf_fllast = cpu_to_be32(XFS_AGFL_SIZE(mp) - 1); + agf->agf_flfirst = cpu_to_be32(1); + agf->agf_fllast = 0; agf->agf_flcount = 0; tmpsize = agsize - XFS_PREALLOC_BLOCKS(mp); agf->agf_freeblks = cpu_to_be32(tmpsize); -- cgit From 253f4911f297b83745938b7f2c5649b94730b002 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 6 Apr 2016 09:19:55 +1000 Subject: xfs: better xfs_trans_alloc interface Merge xfs_trans_reserve and xfs_trans_alloc into a single function call that returns a transaction with all the required log and block reservations, and which allows passing transaction flags directly to avoid the cumbersome _xfs_trans_alloc interface. While we're at it we also get rid of the transaction type argument that has been superflous since we stopped supporting the non-CIL logging mode. The guts of it will be removed in another patch.
