(Without this feature, if xfs could not allocate contiguous +space for 64 new inodes, inode creation would fail.) + +In practice, the disk format change is restricted to the inode btree, +which as far as I can tell is not used by grub. If all you're doing +today is parsing a directory, reading an inode number, and converting +that inode number to a disk location, then ignoring this feature +should be fine, so I've added it to XFS_SB_FEAT_INCOMPAT_SUPPORTED + +I did some brief testing of this patch by hacking up the regression +tests to completely fragment freespace on the test xfs filesystem, and +then write a large-ish number of inodes to consume any existing +contiguous 64-inode chunk. This way any files the grub tests add and +traverse would be in such a fragmented inode allocation. Tests passed, +but I'm not sure how to cleanly integrate that into the test harness. + +Signed-off-by: Eric Sandeen +Reviewed-by: Daniel Kiper +Tested-by: Chris Murphy +--- + grub-core/fs/xfs.c | 11 ++++++++++- + 1 file changed, 10 insertions(+), 1 deletion(-) + +diff --git a/grub-core/fs/xfs.c b/grub-core/fs/xfs.c +index c6031bd..3b00c74 100644 +--- a/grub-core/fs/xfs.c ++++ b/grub-core/fs/xfs.c +@@ -79,9 +79,18 @@ GRUB_MOD_LICENSE ("GPLv3+"); + #define XFS_SB_FEAT_INCOMPAT_SPINODES (1 << 1) /* sparse inode chunks */ + #define XFS_SB_FEAT_INCOMPAT_META_UUID (1 << 2) /* metadata UUID */ + +-/* We do not currently verify metadata UUID so it is safe to read such filesystem */ ++/* ++ * Directory entries with ftype are explicitly handled by GRUB code. ++ * ++ * We do not currently read the inode btrees, so it is safe to read filesystems ++ * with the XFS_SB_FEAT_INCOMPAT_SPINODES feature. ++ * ++ * We do not currently verify metadata UUID, so it is safe to read filesystems ++ * with the XFS_SB_FEAT_INCOMPAT_META_UUID feature. ++ */ + #define XFS_SB_FEAT_INCOMPAT_SUPPORTED \ + (XFS_SB_FEAT_INCOMPAT_FTYPE | \ ++ XFS_SB_FEAT_INCOMPAT_SPINODES | \ + XFS_SB_FEAT_INCOMPAT_META_UUID) + + struct grub_xfs_sblock +-- +cgit v1.0-41-gc330 +
