Hi all, This patchset hoists the code that checks log intent record validation into separate functions, and reworks them to use the standard field validation predicates instead of open-coding them. This strengthens log recovery against (some) fuzzed log items. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. 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=fix-recovered-log-intent-validation-5.11 --- fs/xfs/xfs_bmap_item.c | 75 ++++++++++++++++++++++++++++---------------- fs/xfs/xfs_extfree_item.c | 31 ++++++++++++------ fs/xfs/xfs_log_recover.c | 5 ++- fs/xfs/xfs_refcount_item.c | 61 ++++++++++++++++++++++-------------- fs/xfs/xfs_rmap_item.c | 75 ++++++++++++++++++++++++++++---------------- fs/xfs/xfs_trace.h | 19 +++++++++++ 6 files changed, 178 insertions(+), 88 deletions(-)
