Hi all, Here's one last round of fixes for UAF bugs and memory leaks that I found while testing the logged xattr code. The first patch is a bug for a memory leak in quotacheck that has been popping up here and there for the last 10 years, and the rest are previously seen patches rebased against where I /think/ Dave's current internal testing tree is right now, based on his request on IRC Friday night. 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=larp-fixes-5.19 --- fs/xfs/libxfs/xfs_attr.c | 6 + fs/xfs/libxfs/xfs_attr.h | 11 ++ fs/xfs/libxfs/xfs_defer.c | 59 ++++++++-- fs/xfs/xfs_attr_item.c | 268 +++++++++++++++++++++++++-------------------- fs/xfs/xfs_attr_item.h | 13 ++ fs/xfs/xfs_log.h | 7 + fs/xfs/xfs_qm.c | 9 +- 7 files changed, 235 insertions(+), 138 deletions(-)
