Hi all, While doing QA of the online fsck code, I made a few observations: First, nobody was checking that the di_onlink field is actually zero; Second, that allocating a temporary file for repairs can fail (and thus bring down the entire fs) if the inode cluster is corrupt; and Third, that file link counts do not pin at ~0U to prevent integer overflows. This scattered patchset fixes those three problems. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy! Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=inode-repair-improvements xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=inode-repair-improvements --- Commits in this patchset: * xfs_{db,repair}: add an explicit owner field to xfs_da_args * libxfs: port the bumplink function from the kernel * mkfs/repair: pin inodes that would otherwise overflow link count --- db/namei.c | 1 + include/xfs_inode.h | 2 ++ libxfs/util.c | 18 ++++++++++++++++++ mkfs/proto.c | 4 ++-- repair/incore_ino.c | 3 ++- repair/phase6.c | 13 ++++++++----- 6 files changed, 33 insertions(+), 8 deletions(-)
