hfs: fix BUG on bnode parent update
hfs_brec_update_parent() may hit BUG_ON() if the first record of both a leaf node and its parent are changed, and if this forces the parent to be split. It is not possible for this to happen on a valid hfs filesystem because the index nodes have fixed length keys. For reasons I ignore, the hfs module does have support for a number of hfsplus features. A corrupt btree header may report variable length keys and trigger this BUG, so it's better to fix it.

hfs: prevent btree data loss on root split
This bug is triggered whenever hfs_brec_update_parent() needs to split the root node. The height of the btree is not increased, which leaves the new node orphaned and its records lost. It is not possible for this to happen on a valid hfs filesystem because the index nodes have fixed length keys. For reasons I ignore, the hfs module does have support for a number of hfsplus features. A corrupt btree header may report variable length keys and trigger this bug, so it's better to fix it.

hfsplus: fix BUG on bnode parent update
Creating, renaming or deleting a file may hit BUG_ON() if the first record of both a leaf node and its parent are changed, and if this forces the parent to be split. This bug is triggered by xfstests generic/027, somewhat rarely; here is a more reliable reproducer: truncate -s 50M fs.iso mkfs.hfsplus fs.iso mount fs.iso /mnt i=1000 while [ $i -le 2400 ]; do touch /mnt/$i &>/dev/null ((++i)) done i=2400 while [ $i -ge 1000 ]; do mv /mnt/$i /mnt/$(perl -e "print $i x61") &>/dev/null ((--i)) done The issue is that a newly created bnode is being put twice. Reset new_node to NULL in hfs_brec_update_parent() before reaching goto again.

hfsplus: prevent btree data loss on root split
Creating, renaming or deleting a file may cause catalog corruption and data loss. This bug is randomly triggered by xfstests generic/027, but here is a faster reproducer: truncate -s 50M fs.iso mkfs.hfsplus fs.iso mount fs.iso /mnt i=100 while [ $i -le 150 ]; do touch /mnt/$i &>/dev/null ((++i)) done i=100 while [ $i -le 150 ]; do mv /mnt/$i /mnt/$(perl -e "print $i x82") &>/dev/null ((++i)) done umount /mnt fsck.hfsplus -n fs.iso The bug is triggered whenever hfs_brec_update_parent() needs to split the root node. The height of the btree is not increased, which leaves the new node orphaned and its records lost.

Pull XArray conversion from Matthew Wilcox: "The XArray provides an improved interface to the radix tree data structure, providing locking as part of the API, specifying GFP flags at allocation time, eliminating preloading, less re-walking the tree, more efficient iterations and not exposing RCU-protected pointers to its users. This patch set 1. Introduces the XArray implementation 2. Converts the pagecache to use it 3. Converts memremap to use it The page cache is the most complex and important user of the radix tree, so converting it was most important. Converting the memremap code removes the only other user of the multiorder code, which allows us to remove the radix tree code that supported it. I have 40+ followup patches to convert many other users of the radix tree over to the XArray, but I'd like to get this part in first. The other conversions haven't been in linux-next and aren't suitable for applying yet, but you can see them in the xarray-conv branch if you're interested" * 'xarray' of git://git.infradead.org/users/willy/linux-dax: (90 commits) radix tree: Remove multiorder support radix tree test: Convert multiorder tests to XArray radix tree tests: Convert item_delete_rcu to XArray radix tree tests: Convert item_kill_tree to XArray radix tree tests: Move item_insert_order radix tree test suite: Remove multiorder benchmarking radix tree test suite: Remove __item_insert memremap: Convert to XArray xarray: Add range store functionality xarray: Move multiorder_check to in-kernel tests xarray: Move multiorder_shrink to kernel tests xarray: Move multiorder account test in-kernel radix tree test suite: Convert iteration test to XArray radix tree test suite: Convert tag_tagged_items to XArray radix tree: Remove radix_tree_clear_tags radix tree: Remove radix_tree_maybe_preload_order radix tree: Remove split/join code radix tree: Remove radix_tree_update_node_t page cache: Finish XArray conversion dax: Convert page fault handlers to XArray ... |

mm: zero-seek shrinkers
The page cache and most shrinkable slab caches hold data that has been read from disk, but there are some caches that only cache CPU work, such as the dentry and inode caches of procfs and sysfs, as well as the subset of radix tree nodes that track non-resident page cache. Currently, all these are shrunk at the same rate: using DEFAULT_SEEKS for the shrinker's seeks setting tells the reclaim algorithm that for every two page cache pages scanned it should scan one slab object. This is a bogus setting. A virtual inode that required no IO to create is not twice as valuable as a page cache page; shadow cache entries with eviction distances beyond the size of memory aren't either. In most cases, the behavior in practice is still fine. Such virtual caches don't tend to grow and assert themselves aggressively, and usually get picked up before they cause problems. But there are scenarios where that's not true. Our database workloads suffer from two of those. For one, their file workingset is several times bigger than available memory, which has the kernel aggressively create shadow page cache entries for the non-resident parts of it. The workingset code does tell the VM that most of these are expendable, but the VM ends up balancing them 2:1 to cache pages as per the seeks setting. This is a huge waste of memory. These workloads also deal with tens of thousands of open files and use /proc for introspection, which ends up growing the proc_inode_cache to absurdly large sizes - again at the cost of valuable cache space, which isn't a reasonable trade-off, given that proc inodes can be re-created without involving the disk. This patch implements a "zero-seek" setting for shrinkers that results in a target ratio of 0:1 between their objects and IO-backed caches. This allows such virtual caches to grow when memory is available (they do cache/avoid CPU work after all), but effectively disables them as soon as IO-backed objects are under pressure. It then switches the shrinkers for procfs and sysfs metadata, as well as excess page cache shadow nodes, to the new zero-seek setting.

mm, proc: add KReclaimable to /proc/meminfo
The vmstat NR_KERNEL_MISC_RECLAIMABLE counter is for kernel non-slab allocations that can be reclaimed via shrinker. In /proc/meminfo, we can show the sum of all reclaimable kernel allocations (including slab) as "KReclaimable". Add the same counter also to per-node meminfo under /sys With this counter, users will have more complete information about kernel memory usage. Non-slab reclaimable pages (currently just the ION allocator) will not be missing from /proc/meminfo, making users wonder where part of their memory went. More precisely, they already appear in MemAvailable, but without the new counter, it's not obvious why the value in MemAvailable doesn't fully correspond with the sum of other counters participating in it.

dcache: allocate external names from reclaimable kmalloc caches
We can use the newly introduced kmalloc-reclaimable-X caches, to allocate
external names in dcache, which will take care of the proper accounting
automatically, and also improve anti-fragmentation page grouping.

userfaultfd: disable irqs when taking the waitqueue lock
userfaultfd contains howe-grown locking of the waitqueue lock, and does not disable interrupts.

With aio poll it is easy to trigger other locks that disable interrupts (or are called from interrupt context).

fsnotify: Fix busy inodes during unmount
Detaching of mark connector from fsnotify_put_mark() can race with
unmounting of the filesystem like:
CPU1 CPU2
fsnotify_put_mark()
spin_lock(&conn->lock);
...
inode = fsnotify_detach_connector_from_object(conn)
spin_unlock(&conn->lock);
generic_shutdown_super()
fsnotify_unmount_inodes()
sees connector detached for inode
-> nothing to do
evict_inode()
barfs on pending inode reference
iput(inode);
Resulting in "Busy inodes after unmount" message and possible kernel
oops. Make fsnotify_unmount_inodes() properly wait for outstanding inode
references from detached connectors.
Note that the accounting of outstanding inode references in the
superblock can cause some cacheline contention on the counter. OTOH it
happens only during deletion of the last notification mark from an inode
(or during unlinking of watched inode) and that is not too bad. I have
measured time to create & delete inotify watch 100000 times from 64
processes in parallel (each process having its own inotify group and its
own file on a shared superblock) on a 64 CPU machine. Average and
standard deviation of 15 runs look like:
Avg Stddev
Vanilla 9.817400 0.276165
Fixed 9.710467 0.228294
So there's no statistically significant difference.

f2fs-for-4.20-rc1
In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata. Enhancement: - add checksum to keep superblock contents more safe - add checkpoint=disable/enable to support A/B update of entire filesystem - use plug for readahead IO in readdir - add more IO counts to avoid block layer hacks Bug fix: - prevent data corruption issue for hardware encryption - fix IO hang issues when GC is heavily triggered - add missing up_read in __write_node_page - recover inode metadata during roll-forward recovery flow - fix null pointer dereference issue in wrongly configured discard map There are some more sanity checks and minor bug fixes as well. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAlvPzt4ACgkQQBSofoJI UNJLfg/8Ch9TWfbeUEH+6ioJ4pdURHmb/gFOQRSGX8Nu+HkuPJQD8pqlheK7n5g7 Pw3K6NLXHmL2d8xSNFbBwYmUSAeoXTc0J4nqX0sUJ6m7SKsuQ45Qe3A90faKEoAA ce7flWKVI+aJcGurBe99GOM69ptfyjb1w/8UGB0pcXUDq4oaRv5a1UtAAm92WF7H 4/7jYD3ub5aeSynwe16wWR4B5aXJT0l0FcZYicI6IRY1mOjMtXuQt72AY+ffSzBt yQ6qb8OEl3xpfQZHHH00ZfvarkTBzXJGZwquiPX/CPzVcee8cOqPp+XZqN7CXBEr 9ItezxYiUxOkKCl12Al8DynHZa6o2kEnWxgd49WkL/cNdInnvf5MD0kdfCV3KfQa CAR0UVe2yTg5mGLemtTSWveLdHfI7+LhDmURuXmoTUa9GWldw0413qqVVypcsizv QOAS86hSicrVK+bDnCA70i8Xxw7YEnAyrfCcgihU84NZSi7nTPUYj4xtMd9SzRnK JO8gA79D7lcWaxUS4r9I+JBDwWcfMQZRPS7PFbvoGWilIwsEaocCPYNgtjCTsAsK 1fePqiF/265Q4lapmEhEjhuQSNH2xfJQZ4ux1OU+eS3OTDjbEAFBeVPZImh7Mo7F dkpXQwfcqAXPzOM4QAJ6hFX40D8SWMAlId6XGiIfJlrFmEUAxBk= =VDw4 -----END PGP SIGNATURE----- Merge tag 'f2fs-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata.

Preliminary results show eg. more files/sec in fsmark, better perf on multi-threaded workloads (filebench, dbench), fewer context switches and overall better memory allocation characteristics (multiple benchmarks). Apart from general performance, there's an improvement for qgroups + balance workload that's been troubling our users. Note for stable: there are 20+ patches tagged for stable, out of 90. Not all of them apply cleanly on all stable versions but the conflicts are mostly due to simple cleanups and resolving should be obvious. The fixes are otherwise independent. Performance improvements: - transition between blocking and spinning modes of path is gone, which originally resulted to more unnecessary wakeups and updates to the path locks, the effects are measurable and improve latency and scalability - qgroups: first batch of changes that should speedup balancing with qgroups on, skip quota accounting on unchanged subtrees, overall gain is about 30+% in runtime - use rb-tree with cached first node for several structures, small improvement to avoid pointer chasing Fixes: - trim - fix: some blockgroups could have been missed if their logical address was past the total filesystem size (ie. after a lot of balancing) - better error reporting, after processing blockgroups and whole device - fix: continue trimming block groups after an error is encountered - check for trim support of the device earlier and avoid some unnecessary work - less interaction with transaction commit that improves latency on slower storage (eg. image files over NFS) - fsync - fix warning when replaying log after fsync of a O_TMPFILE - fix wrong dentries after fsync of file that got its parent replaced - qgroups: fix rescan that might misc some dirty groups - don't clean dirty pages during buffered writes, this could lead to lost updates in some corner cases - some block groups could have been delayed in creation, if the allocation triggered another one - error handling improvements Cleanups: - removed unused struct members and variables - function return type cleanups - delayed refs code refactoring - protect against deadlock that could be caused by crafted image that tries to allocate from a tree that's locked already" * tag 'for-4.20-part1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (93 commits) btrfs: switch return_bigger to bool in find_ref_head btrfs: remove fs_info from btrfs_should_throttle_delayed_refs btrfs: remove fs_info from btrfs_check_space_for_delayed_refs btrfs: delayed-ref: pass delayed_refs directly to btrfs_delayed_ref_lock btrfs: delayed-ref: pass delayed_refs directly to btrfs_select_ref_head btrfs: qgroup: move the qgroup->members check out from (!qgroup)'s else branch btrfs: relocation: Remove redundant tree level check btrfs: relocation: Cleanup while loop using rbtree_postorder_for_each_entry_safe btrfs: qgroup: Avoid calling qgroup functions if qgroup is not enabled Btrfs: fix wrong dentries after fsync of file that got its parent replaced Btrfs: fix warning when replaying log after fsync of a tmpfile btrfs: drop min_size from evict_refill_and_join btrfs: assert on non-empty delayed iputs btrfs: make sure we create all new block groups btrfs: reset max_extent_size on clear in a bitmap btrfs: protect space cache inode alloc with GFP_NOFS btrfs: release metadata before running delayed refs Btrfs: kill btrfs_clear_path_blocking btrfs: dev-replace: remove pointless assert in write unlock btrfs: dev-replace: move replace members out of fs_info ... |

cifs: allow calling SMB2_xxx_free(NULL)
Change these free functions to allow passing NULL as the argument and
treat it as a no-op just like free(NULL) would.
Or, if rqst->rq_iov is NULL.
The second scenario could happen for smb2_queryfs() if the call
to SMB2_query_info_init() fails and we go to qfs_exit to clean up
and free all resources.
In that case we have not yet assigned rqst[2].rq_iov and thus
the rq_iov dereference in SMB2_close_free() will cause a NULL pointer
dereference.

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo updates from Eric Biederman: "I have been slowly sorting out siginfo and this is the culmination of that work. The primary result is in several ways the signal infrastructure has been made less error prone. The code has been updated so that manually specifying SEND_SIG_FORCED is never necessary. The conversion to the new siginfo sending functions is now complete, which makes it difficult to send a signal without filling in the proper siginfo fields. At the tail end of the patchset comes the optimization of decreasing the size of struct siginfo in the kernel from 128 bytes to about 48 bytes on 64bit. The fundamental observation that enables this is by definition none of the known ways to use struct siginfo uses the extra bytes. This comes at the cost of a small user space observable difference. For the rare case of siginfo being injected into the kernel only what can be copied into kernel_siginfo is delivered to the destination, the rest of the bytes are set to 0. For cases where the signal and the si_code are known this is safe, because we know those bytes are not used. For cases where the signal and si_code combination is unknown the bits that won't fit into struct kernel_siginfo are tested to verify they are zero, and the send fails if they are not. I made an extensive search through userspace code and I could not find anything that would break because of the above change. If it turns out I did break something it will take just the revert of a single change to restore kernel_siginfo to the same size as userspace siginfo. Testing did reveal dependencies on preferring the signo passed to sigqueueinfo over si->signo, so bit the bullet and added the complexity necessary to handle that case. Testing also revealed bad things can happen if a negative signal number is passed into the system calls. Something no sane application will do but something a malicious program or a fuzzer might do. So I have fixed the code that performs the bounds checks to ensure negative signal numbers are handled" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (80 commits) signal: Guard against negative signal numbers in copy_siginfo_from_user32 signal: Guard against negative signal numbers in copy_siginfo_from_user signal: In sigqueueinfo prefer sig not si_signo signal: Use a smaller struct siginfo in the kernel signal: Distinguish between kernel_siginfo and siginfo signal: Introduce copy_siginfo_from_user and use it's return value signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE signal: Fail sigqueueinfo if si_signo != sig signal/sparc: Move EMT_TAGOVF into the generic siginfo.h signal/unicore32: Use force_sig_fault where appropriate signal/unicore32: Generate siginfo in ucs32_notify_die signal/unicore32: Use send_sig_fault where appropriate signal/arc: Use force_sig_fault where appropriate signal/arc: Push siginfo generation into unhandled_exception signal/ia64: Use force_sig_fault where appropriate signal/ia64: Use the force_sig(SIGSEGV,...) in ia64_rt_sigreturn signal/ia64: Use the generic force_sigsegv in setup_frame signal/arm/kvm: Use send_sig_mceerr signal/arm: Use send_sig_fault where appropriate signal/arm: Use force_sig_fault where appropriate ... |
