[PATCH 1/4] ext4: fix double-free of blocks due to wrong extents moved_len

by Baokun Li

In ext4_move_extents(), moved_len is only updated when all moves are successfully executed, and only discards orig_inode and donor_inode preallocations when moved_len is not zero. When the loop fails to exit after successfully moving some extents, moved_len is not updated and remains at 0, so it does not discard the preallocations. If the moved extents overlap with the preallocated extents, the overlapped extents are freed twice in ext4_mb_release_inode_pa() and ext4_process_freed_data() (as described in commit 94d7c16cbbbd), and bb_free is incremented twice. Hence when trim is executed, a zero-division bug is triggered in mb_update_avg_fragment_size() because bb_free is not zero and bb_fragments is zero. Therefore, update move_len after each extent move to avoid the issue.

IMA performance regression in 5.10.194 when using overlayfs

by rkolchmeyer＠google.com

Hi all, 5.10.194 includes 331d85f0bc6e (ovl: Always reevaluate the file signature for IMA), which resulted in a performance regression for workloads that use IMA and run from overlayfs. 5.10.202 includes cd5a262a07a5 (ima: detect changes to the backing overlay file), which resolved the regression in the upstream kernel. However, from my testing [1], this change doesn't resolve the regression on stable kernels. From what I can tell, cd5a262a07a5 (ima: detect changes to the backing overlay file) depends on both db1d1e8b9867 (IMA: use vfs_getattr_nosec to get the i_version) and a1175d6b1bda (vfs: plumb i_version handling into struct kstat). These two dependent changes were not backported to stable kernels. As a result, IMA seems to be caching the wrong i_version value when using overlayfs. From my testing, backporting these two dependent changes is sufficient to resolve the issue in stable kernels. Would it make sense to backport those changes to stable kernels? It's possible that they may not follow the stable kernel patching rules. I think the issue can also be fixed directly in stable trees with the following diff (which doesn't make sense in the upstream kernel): diff --git a/security/integrity/ima/ima_api.c b/security/integrity/ima/ima_api.c index 70efd4aa1bd1..c84ae6b62b3a 100644 --- a/security/integrity/ima/ima_api.c +++ b/security/integrity/ima/ima_api.c @@ -239,7 +239,7 @@ int ima_collect_measurement(struct integrity_iint_cache *iint, * which do not support i_version, support is limited to an initial * measurement/appraisal/audit. */ - i_version = inode_query_iversion(inode); + i_version = inode_query_iversion(real_inode); hash.hdr.algo = algo; /* Initialize hash digest to 0's in case of failure */ I've verified that this diff resolves the performance regression. Which approach would make the most sense to fix the issue in stable kernels? Backporting the dependent commits, or merging the above diff? I'd be happy to prepare and mail patches either way. Looking forward to your thoughts. Thanks, -Robert [1] I'm benchmarking with the following: cat <<EOF > /sys/kernel/security/ima/policy audit func=BPRM_CHECK audit func=FILE_MMAP mask=MAY_EXEC EOF docker run --rm debian bash -c "TIMEFORMAT=%3R; time bash -c :" A good result looks like 0.002 (units are seconds), and a bad result looks like 0.034.

However, commit 0f91d13366a4 ("mm/damon: simplify stop mechanism") made neither damon_start() nor damon_stop() ensure the corresponding kdamond has started the execution of kdamond_fn(). As a result, the cleanup can be skipped if damon_stop() is called fast enough after the previous damon_start(). Especially the skipped reset of ->kdamond could cause a use-after-free. Fix it by waiting for start of kdamond_fn() execution from damon_start().
