The walk to destroy the nodes was not always setting the node type and would result in a destroy method potentially using the values as nodes. Avoid this by setting the correct node types. This is necessary for the RCU mode of the maple tree. Link: https://lkml.kernel.org/r/20230227173632.3292573-4-surenb@google.com Fixes: 54a611b6 ("Maple Tree: add new data structure") Signed-off-by:

When initially starting a search, the root node may already be in the process of being replaced in RCU mode. Detect and restart the walk if this is the case.

Patch series "Fix VMA tree modification under mmap read lock". Syzbot reported a BUG_ON in mm/mmap.c which was found to be caused by an inconsistency between threads walking the VMA maple tree. The inconsistency is caused by the page fault handler modifying the maple tree while holding the mmap_lock for read. This only happens for stack VMAs. We had thought this was safe as it only modifies a single pivot in the tree. Unfortunately, syzbot constructed a test case where the stack had no guard page and grew the stack to abut the next VMA. This causes us to delete the NULL entry between the two VMAs and rewrite the node. We considered several options for fixing this, including dropping the mmap_lock, then reacquiring it for write; and relaxing the definition of the tree to permit a zero-length NULL entry in the node. We decided the best option was to backport some of the RCU patches from -next, which solve the problem by allocating a new node and RCU-freeing the old node. Since the problem exists in 6.1, we preferred a solution which is similar to the one we intended to merge next merge window. These patches have been in -next since next-20230301, and have received intensive testing in Android as part of the RCU page fault patchset. They were also sent as part of the "Per-VMA locks" v4 patch series. Patches 1 to 7 are bug fixes for RCU mode of the tree and patch 8 enables RCU mode for the tree. Performance v6.3-rc3 vs patched v6.3-rc3: Running these changes through mmtests showed there was a 15-20% performance decrease in will-it-scale/brk1-processes. This tests creating and inserting a single VMA repeatedly through the brk interface and isn't representative of any real world applications. This patch (of 8): ma_pivots() and ma_data_end() may be called with a dead node. Ensure to that the node isn't dead before using the returned values. This is necessary for RCU mode of the maple tree.

The struct pages could be discontiguous when the kfence pool is allocated via alloc_contig_pages() with CONFIG_SPARSEMEM and !CONFIG_SPARSEMEM_VMEMMAP. This may result in setting PG_slab and memcg_data to a arbitrary address (may be not used as a struct page), which in the worst case might corrupt the kernel. So the iteration should use nth_page().

It does not reset PG_slab and memcg_data when KFENCE fails to initialize kfence pool at runtime. It is reporting a "Bad page state" message when kfence pool is freed to buddy. The checking of whether it is a compound head page seems unnecessary since we already guarantee this when allocating kfence pool. Remove the check to simplify the code.

Pull xfs percpu counter fixes from Darrick Wong: "We discovered a filesystem summary counter corruption problem that was traced to cpu hot-remove racing with the call to percpu_counter_sum that sets the free block count in the superblock when writing it to disk. The root cause is that percpu_counter_sum doesn't cull from dying cpus and hence misses those counter values if the cpu shutdown hooks have not yet run to merge the values. I'm hoping this is a fairly painless fix to the problem, since the dying cpu mask should generally be empty. It's been in for-next for a week without any complaints from the bots. - Fix a race in the percpu counters summation code where the summation failed to add in the values for any CPUs that were dying but not yet dead.

Merge tag 'for-6.3/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix DM thin to work as a swap device by using 'limit_swap_bios' DM target flag (initially added to allow swap to dm-crypt) to throttle the amount of outstanding swap bios. - Fix DM crypt soft lockup warnings by calling cond_resched() from the cpu intensive loop in dmcrypt_write(). - Fix DM crypt to not access an uninitialized tasklet. This fix allows for consistent handling of IO completion, by _not_ needlessly punting to a workqueue when tasklets are not needed. - Fix DM core's alloc_dev() initialization for DM stats to check for and propagate alloc_percpu() failure. * tag 'for-6.3/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm stats: check for and propagate alloc_percpu failure dm crypt: avoid accessing uninitialized tasklet dm crypt: add cond_resched() to dmcrypt_write() dm thin: fix deadlock when swapping to thin device

At some point in between sending this patch to the list and merging it into for-next, the tracepoints got all mixed up because I've over-reliant on automated tools not sucking. The end result is that the tracepoints are all wrong, so fix them. Signed-off-by:

If user does forced unmount ("umount -f") while files are still open on the share (as was seen in a Kubernetes example running on SMB3.1.1 mount) then we were marking the share as "TID_EXITING" in umount_begin() which caused all subsequent operations (except write) to fail ... but unfortunately when umount_begin() is called we do not know yet that there are open files or active references on the share that would prevent unmount from succeeding. Kubernetes had example when they were doing umount -f when files were open which caused the share to become unusable until the files were closed (and the umount retried). Fix this so that TID_EXITING is not set until we are about to send the tree disconnect (not at the beginning of forced umounts in umount_begin) so that if "umount -f" fails (due to open files or references) the mount is still usable.

Get rid of any prefix paths in @path before lookup_positive_unlocked() as it will call ->lookup() which already adds those prefix paths through build_path_from_dentry(). This has caused a performance regression when mounting shares with a prefix path where readdir(2) would end up retrying several times to open bad directory names that contained duplicate prefix paths. Fix this by skipping any prefix paths in @path before calling lookup_positive_unlocked().

Performance tests with large number of threads noted that the change of the default closetimeo (deferred close timeout between when close is done by application and when client has to send the close to the server), to 5 seconds from 1 second, significantly degraded perf in some cases like this (in the filebench example reported, the stats show close requests on the wire taking twice as long, and 50% regression in filebench perf). This is stil configurable via mount parm closetimeo, but to be safe, decrease default back to its previous value of 1 second. Reported-by:
