FROMGIT: f2fs: fix to avoid use SSR allocate when do defragment
SSR allocate mode will be used when doing file defragment
if ATGC is working at the same time, that is because
set_page_private_gcing may make CURSEG_ALL_DATA_ATGC segment
type got in f2fs_allocate_data_block when defragment page
is writeback, which may cause file fragmentation is worse.
A file with 2 fragmentations is changed as following after defragment:

UPSTREAM: epoll: be better about file lifetimes
epoll can call out to vfs_poll() with a file pointer that may race with the last 'fput()'. That would make f_count go down to zero, and while the ep->mtx locking means that the resulting file pointer tear-down will be blocked until the poll returns, it means that f_count is already dead, and any use of it won't actually get a reference to the file any more: it's dead regardless. Make sure we have a valid ref on the file pointer before we call down to vfs_poll() from the epoll routines.

ANDROID: 16K: Fix show maps CFI failure
If the kernel is built CONFIG_CFI_CLANG=y, reading smaps may cause a panic. This is due to a failed CFI check; which is triggered becuase the signature of the function pointer for printing smaps padding VMAs does not match exactly with that for show_smap(). Fix this by casting the function pointer to the expected type based on whether printing maps or smaps padding.

ANDROID: 16K: Handle pad VMA splits and merges
In some cases a VMA with padding representation may be split, and
therefore the padding flags must be updated accordingly.
There are 3 cases to handle:
Given:
| DDDDPPPP |
where:
- D represents 1 page of data;
- P represents 1 page of padding;
- | represents the boundaries (start/end) of the VMA
1) Split exactly at the padding boundary
| DDDDPPPP | --> | DDDD | PPPP |
- Remove padding flags from the first VMA.
- The second VMA is all padding
2) Split within the padding area
| DDDDPPPP | --> | DDDDPP | PP |
- Subtract the length of the second VMA from the first VMA's
padding.
- The second VMA is all padding, adjust its padding length (flags)
3) Split within the data area
| DDDDPPPP | --> | DD | DDPPPP |
- Remove padding flags from the first VMA.
- The second VMA is has the same padding as from before the split.
To simplify the semantics merging of padding VMAs is not allowed.
If a split produces a VMA that is entirely padding, show_[s]maps()
only outputs the padding VMA entry (as the data entry is of length 0).

ANDROID: 16K: Separate padding from ELF LOAD segment mappings
In has been found that some in-field apps depend on the output of
/proc/*/maps to determine the address ranges of other operations.
With the extension of LOAD segments VMAs to be contiguous in memory,
the apps may perform operations on an area that is not backed by the
underlying file, which results in a SIGBUS. Other apps have crashed
with yet unindentified reasons.
To avoid breaking in-field apps, maintain the output of /proc/*/[s]maps
with PROT_NONE VMAs for the padding pages of LOAD segments instead of
showing the segment extensions.
NOTE: This does not allocate actual backing VMAs for the shown
PROT_NONE mappings.
This approach maintains 2 possible assumptions that userspace (apps)
could be depending on:
1) That LOAD segment mappings are "contiguous" (not speparated by
unrelated mappings) in memory.
2) That no virtual address space is available between mappings of
consecutive LOAD segments for the same ELF.
For example the output of /proc/*/[s]maps before and after this change
is shown below. Segments maintain PROT_NONE gaps ("[page size compat]")
for app compatiblity but these are not backed by actual slab VMA memory.

BACKPORT: userfaultfd: protect mmap_changing with rw_sem in userfaulfd_ctx
Increments and loads to mmap_changing are always in mmap_lock critical section. This ensures that if userspace requests event notification for non-cooperative operations (e.g. mremap), userfaultfd operations don't occur concurrently. This can be achieved by using a separate read-write semaphore in userfaultfd_ctx such that increments are done in write-mode and loads in read-mode, thereby eliminating the dependency on mmap_lock for this purpose. This is a preparatory step before we replace mmap_lock usage with per-vma locks in fill/move ioctls.

BACKPORT: userfaultfd: move userfaultfd_ctx struct to header file
Patch series "per-vma locks in userfaultfd", v7. Performing userfaultfd operations (like copy/move etc.) in critical section of mmap_lock (read-mode) causes significant contention on the lock when operations requiring the lock in write-mode are taking place concurrently. We can use per-vma locks instead to significantly reduce the contention issue. Android runtime's Garbage Collector uses userfaultfd for concurrent compaction. mmap-lock contention during compaction potentially causes jittery experience for the user. During one such reproducible scenario, we observed the following improvements with this patch-set: - Wall clock time of compaction phase came down from ~3s to <500ms - Uninterruptible sleep time (across all threads in the process) was ~10ms (none in mmap_lock) during compaction, instead of >20s This patch (of 4): Move the struct to userfaultfd_k.h to be accessible from mm/userfaultfd.c. There are no other changes in the struct. This is required to prepare for using per-vma locks in userfaultfd operations.

UPSTREAM: userfaultfd: fix return error if mmap_changing is non-zero in MOVE ioctl
To be consistent with other uffd ioctl's returning EAGAIN when mmap_changing is detected, we should change UFFDIO_MOVE to do the same.

BACKPORT: userfaultfd: UFFDIO_MOVE uABI
Implement the uABI of UFFDIO_MOVE ioctl. UFFDIO_COPY performs ~20% better than UFFDIO_MOVE when the application needs pages to be allocated [1]. However, with UFFDIO_MOVE, if pages are available (in userspace) for recycling, as is usually the case in heap compaction algorithms, then we can avoid the page allocation and memcpy (done by UFFDIO_COPY). Also, since the pages are recycled in the userspace, we avoid the need to release (via madvise) the pages back to the kernel [2]. We see over 40% reduction (on a Google pixel 6 device) in the compacting thread's completion time by using UFFDIO_MOVE vs. UFFDIO_COPY. This was measured using a benchmark that emulates a heap compaction implementation using userfaultfd (to allow concurrent accesses by application threads). More details of the usecase are explained in [2]. Furthermore, UFFDIO_MOVE enables moving swapped-out pages without touching them within the same vma. Today, it can only be done by mremap, however it forces splitting the vma. [1] https://lore.kernel.org/all/1425575884-2574-1-git-send-email-aarcange@redhat.com/ [2] https://lore.kernel.org/linux-mm/CA+EESO4uO84SSnBhArH4HvLNhaUQ5nZKNKXqxRCyjniNVjp0Aw@mail.gmail.com/ Update for the ioctl_userfaultfd(2) manpage: UFFDIO_MOVE (Since Linux xxx) Move a continuous memory chunk into the userfault registered range and optionally wake up the blocked thread. The source and destination addresses and the number of bytes to move are specified by the src, dst, and len fields of the uffdio_move structure pointed to by argp: struct uffdio_move { __u64 dst; /* Destination of move */ __u64 src; /* Source of move */ __u64 len; /* Number of bytes to move */ __u64 mode; /* Flags controlling behavior of move */ __s64 move; /* Number of bytes moved, or negated error */ }; The following value may be bitwise ORed in mode to change the behavior of the UFFDIO_MOVE operation: UFFDIO_MOVE_MODE_DONTWAKE Do not wake up the thread that waits for page-fault resolution UFFDIO_MOVE_MODE_ALLOW_SRC_HOLES Allow holes in the source virtual range that is being moved. When not specified, the holes will result in ENOENT error. When specified, the holes will be accounted as successfully moved memory. This is mostly useful to move hugepage aligned virtual regions without knowing if there are transparent hugepages in the regions or not, but preventing the risk of having to split the hugepage during the operation. The move field is used by the kernel to return the number of bytes that was actually moved, or an error (a negated errno- style value). If the value returned in move doesn't match the value that was specified in len, the operation fails with the error EAGAIN. The move field is output-only; it is not read by the UFFDIO_MOVE operation. The operation may fail for various reasons. Usually, remapping of pages that are not exclusive to the given process fail; once KSM might deduplicate pages or fork() COW-shares pages during fork() with child processes, they are no longer exclusive. Further, the kernel might only perform lightweight checks for detecting whether the pages are exclusive, and return -EBUSY in case that check fails. To make the operation more likely to succeed, KSM should be disabled, fork() should be avoided or MADV_DONTFORK should be configured for the source VMA before fork(). This ioctl(2) operation returns 0 on success. In this case, the entire area was moved. On error, -1 is returned and errno is set to indicate the error. Possible errors include: EAGAIN The number of bytes moved (i.e., the value returned in the move field) does not equal the value that was specified in the len field. EINVAL Either dst or len was not a multiple of the system page size, or the range specified by src and len or dst and len was invalid. EINVAL An invalid bit was specified in the mode field. ENOENT The source virtual memory range has unmapped holes and UFFDIO_MOVE_MODE_ALLOW_SRC_HOLES is not set. EEXIST The destination virtual memory range is fully or partially mapped. EBUSY The pages in the source virtual memory range are either pinned or not exclusive to the process. The kernel might only perform lightweight checks for detecting whether the pages are exclusive. To make the operation more likely to succeed, KSM should be disabled, fork() should be avoided or MADV_DONTFORK should be configured for the source virtual memory area before fork(). ENOMEM Allocating memory needed for the operation failed. ESRCH The target process has exited at the time of a UFFDIO_MOVE operation.

UPSTREAM: epoll: use refcount to reduce ep_mutex contention
We are observing huge contention on the epmutex during an http
connection/rate test:
83.17% 0.25% nginx [kernel.kallsyms] [k] entry_SYSCALL_64_after_hwframe
[...]
|--66.96%--__fput
|--60.04%--eventpoll_release_file
|--58.41%--__mutex_lock.isra.6
|--56.56%--osq_lock
The application is multi-threaded, creates a new epoll entry for
each incoming connection, and does not delete it before the
connection shutdown - that is, before the connection's fd close().
Many different threads compete frequently for the epmutex lock,
affecting the overall performance.
To reduce the contention this patch introduces explicit reference counting
for the eventpoll struct. Each registered event acquires a reference,
and references are released at ep_remove() time.
The eventpoll struct is released by whoever - among EP file close() and
and the monitored file close() drops its last reference.
Additionally, this introduces a new 'dying' flag to prevent races between
the EP file close() and the monitored file close().
ep_eventpoll_release() marks, under f_lock spinlock, each epitem as dying
before removing it, while EP file close() does not touch dying epitems.
The above is needed as both close operations could run concurrently and
drop the EP reference acquired via the epitem entry. Without the above
flag, the monitored file close() could reach the EP struct via the epitem
list while the epitem is still listed and then try to put it after its
disposal.
An alternative could be avoiding touching the references acquired via
the epitems at EP file close() time, but that could leave the EP struct
alive for potentially unlimited time after EP file close(), with nasty
side effects.
With all the above in place, we can drop the epmutex usage at disposal time.
Overall this produces a significant performance improvement in the
mentioned connection/rate scenario: the mutex operations disappear from
the topmost offenders in the perf report, and the measured connections/rate
grows by ~60%.
To make the change more readable this additionally renames ep_free() to
ep_clear_and_put(), and moves the actual memory cleanup in a separate
ep_free() helper.

This patch separates FAULT_BLKADDR_CONSISTENCE from FAULT_BLKADDR, and rename FAULT_BLKADDR to FAULT_BLKADDR_VALIDITY so that we can: a) use FAULT_BLKADDR_CONSISTENCE in f2fs_truncate_data_blocks_range() to simulate inconsistent issue independently, then it can verify fsck repair flow. b) FAULT_BLKADDR_VALIDITY fault will not cause any inconsistent status, we can just use it to check error path handling in kernel side.

FROMGIT: f2fs: compress: fix to avoid inconsistence bewteen i_blocks and dnode
In reserve_compress_blocks(), we update blkaddrs of dnode in prior to
inc_valid_block_count(), it may cause inconsistent status bewteen
i_blocks and blkaddrs once inc_valid_block_count() fails.
To fix this issue, it needs to reverse their invoking order.

FROMGIT: f2fs: compress: fix to cover normal cluster write with cp_rwsem
When we overwrite compressed cluster w/ normal cluster, we should
not unlock cp_rwsem during f2fs_write_raw_pages(), otherwise data
will be corrupted if partial blocks were persisted before CP & SPOR,
due to cluster metadata wasn't updated atomically.

f2fs: add helper to check compression level
commit c571fbb5b59a3741e48014faa92c2f14bc59fe50 upstream.
This patch adds a helper function to check if compression level is
valid.
Meanwhile, this patch fixes a reported issue [1]:
The issue is easily reproducible by:
1. dd if=/dev/zero of=test.img count=100 bs=1M
2. mkfs.f2fs -f -O compression,extra_attr ./test.img
3. mount -t f2fs -o compress_algorithm=zstd:6,compress_chksum,atgc,gc_merge,lazytime ./test.img /mnt
resulting in

https://bugzilla.kernel.org/show_bug.cgi?id=218471

fs/ntfs3: Fix an NULL dereference bug
[ Upstream commit b2dd7b953c25ffd5912dda17e980e7168bebcf6c ]
The issue here is when this is called from ntfs_load_attr_list(). The
"size" comes from le32_to_cpu(attr->res.data_size) so it can't overflow
on a 64bit systems but on 32bit systems the "+ 1023" can overflow and
the result is zero. This means that the kmalloc will succeed by
returning the ZERO_SIZE_PTR and then the memcpy() will crash with an
Oops on the next line.

cifs: failure to add channel on iface should bump up weight
[ Upstream commit 6aac002bcfd554aff6d3ebb55e1660d078d70ab0 ]
After the interface selection policy change to do a weighted
round robin, each iface maintains a weight_fulfilled. When the
weight_fulfilled reaches the total weight for the iface, we know
that the weights can be reset and ifaces can be allocated from
scratch again.
During channel allocation failures on a particular channel,
weight_fulfilled is not incremented. If a few interfaces are
inactive, we could end up in a situation where the active
interfaces are all allocated for the total_weight, and inactive
ones are all that remain. This can cause a situation where
no more channels can be allocated further.
This change fixes it by increasing weight_fulfilled, even when
channel allocation failure happens. This could mean that if
there are temporary failures in channel allocation, the iface
weights may not strictly be adhered to. But that's still okay.

BACKPORT: erofs: fix infinite loop due to a race of filling compressed_bvecs
I encountered a race issue after lengthy (~594647 sec) stress tests on
a 64k-page arm64 VM with several 4k-block EROFS images. The timing
is like below:
z_erofs_try_inplace_io z_erofs_fill_bio_vec
cmpxchg(&compressed_bvecs[].page,
NULL, ..)
[access bufvec]
compressed_bvecs[] = *bvec;
Previously, z_erofs_submit_queue() just accessed bufvec->page only, so
other fields in bufvec didn't matter. After the subpage block support
is landed, .offset and .end can be used too, but filling bufvec isn't
an atomic operation which can cause inconsistency.
Let's use a spinlock to keep the atomicity of each bufvec.

BACKPORT: f2fs: Restrict max filesize for 16K f2fs
Blocks are tracked by u32, so the max permitted filesize is
(U32_MAX + 1) * BLOCK_SIZE. Additionally, in order to support crypto
data unit sizes of 4K with a 16K block with IV_INO_LBLK_{32,64}, we must
further restrict max filesize to (U32_MAX + 1) * 4096. This does not
affect 4K blocksize f2fs as the natural limit for files are well below
that.

ceph: fix invalid pointer access if get_quota_realm return ERR_PTR
[ Upstream commit 0f4cf64eabc6e16cfc2704f1960e82dc79d91c8d ] This issue is reported by smatch that get_quota_realm() might return ERR_PTR but we did not handle it. It's not a immediate bug, while we still should address it to avoid potential bugs if get_quota_realm() is changed to return other ERR_PTR in future. Set ceph_snap_realm's pointer in get_quota_realm()'s to address this issue, the pointer would be set to NULL if get_quota_realm() failed to get struct ceph_snap_realm, so no ERR_PTR would happen any more.

fs/kernfs/dir: obey S_ISGID
[ Upstream commit 5133bee62f0ea5d4c316d503cc0040cac5637601 ] Handling of S_ISGID is usually done by inode_init_owner() in all other filesystems, but kernfs doesn't use that function. In kernfs, struct kernfs_node is the primary data structure, and struct inode is only created from it on demand. Therefore, inode_init_owner() can't be used and we need to imitate its behavior. S_ISGID support is useful for the cgroup filesystem; it allows subtrees managed by an unprivileged process to retain a certain owner gid, which then enables sharing access to the subtree with another unprivileged process. -- v1 -> v2: minor coding style fix (comment) Signed-off-by: Max Kellermann <max.kellermann@ionos.com> Acked-by: Tejun Heo <tj@kernel.org> Link: https://lore.kernel.org/r/20231208093310.297233-2-max.kellermann@ionos.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org> |

fast_dput(): handle underflows gracefully
[ Upstream commit 504e08cebe1d4e1efe25f915234f646e74a364a8 ] If refcount is less than 1, we should just warn, unlock dentry and return true, so that the caller doesn't try to do anything else. Taking care of that leaves the rest of "lockref_put_return() has failed" case equivalent to "decrement refcount and rejoin the normal slow path after the point where we grab ->d_lock". NOTE: lockref_put_return() is strictly a fastpath thing - unlike the rest of lockref primitives, it does not contain a fallback. Caller (and it looks like fast_dput() is the only legitimate one in the entire kernel) has to do that itself. Reasons for lockref_put_return() failures: * ->d_lock held by somebody * refcount <= 0 * ... or an architecture not supporting lockref use of cmpxchg - sparc, anything non-SMP, config with spinlock debugging... We could add a fallback, but it would be a clumsy API - we'd have to distinguish between: (1) refcount > 1 - decremented, lock not held on return (2) refcount < 1 - left alone, probably no sense to hold the lock (3) refcount is 1, no cmphxcg - decremented, lock held on return (4) refcount is 1, cmphxcg supported - decremented, lock *NOT* held on return. We want to return with no lock held in case (4); that's the whole point of that thing. We very much do not want to have the fallback in case (3) return without a lock, since the caller might have to retake it in that case. So it wouldn't be more convenient than doing the fallback in the caller and it would be very easy to screw up, especially since the test coverage would suck - no way to test (3) and (4) on the same kernel build.

This is because flexbg_size is too large and the size of the new_group_data
array to be allocated exceeds MAX_ORDER. Currently, the minimum value of
MAX_ORDER is 8, the minimum value of PAGE_SIZE is 4096, the corresponding
maximum number of groups that can be allocated is:
(PAGE_SIZE << MAX_ORDER) / sizeof(struct ext4_new_group_data) ≈ 21845
And the value that is down-aligned to the power of 2 is 16384. Therefore,
this value is defined as MAX_RESIZE_BG, and the number of groups added
each time does not exceed this value during resizing, and is added multiple
times to complete the online resizing. The difference is that the metadata
in a flex_bg may be more dispersed.
