pNFS/filelayout: Fix coalescing test for single DS
When there is a single DS no striping constraints need to be placed on the IO. When such constraint is applied then buffered reads don't coalesce to the DS's rsize. Signed-off-by: Olga Kornievskaia <kolga@netapp.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> |

Treewide: Stop corrupting socket's task_frag
Since moving to memalloc_nofs_save/restore, SUNRPC has stopped setting the GFP_NOIO flag on sk_allocation which the networking system uses to decide when it is safe to use current->task_frag. The results of this are unexpected corruption in task_frag when SUNRPC is involved in memory reclaim. The corruption can be seen in crashes, but the root cause is often difficult to ascertain as a crashing machine's stack trace will have no evidence of being near NFS or SUNRPC code. I believe this problem to be much more pervasive than reports to the community may indicate. Fix this by having kernel users of sockets that may corrupt task_frag due to reclaim set sk_use_task_frag = false. Preemptively correcting this situation for users that still set sk_allocation allows them to convert to memalloc_nofs_save/restore without the same unexpected corruptions that are sure to follow, unlikely to show up in testing, and difficult to bisect.

Merge tag 'nfsd-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux
Pull more nfsd updates from Chuck Lever:
"This contains a number of crasher fixes that were not ready for the
initial pull request last week.
In particular, Jeff's patch attempts to address reference count
underflows in NFSD's filecache, which have been very difficult to
track down because there is no reliable reproducer.
Common failure modes:
https://bugzilla.kernel.org/show_bug.cgi?id=216691#c11
https://bugzilla.kernel.org/show_bug.cgi?id=216674#c6
https://bugzilla.redhat.com/show_bug.cgi?id=2138605
The race windows were found by inspection and the clean-ups appear
sensible and pass regression testing, so we include them here in the
hope that they address the problem. However we remain vigilant because
we don't have 100% certainty yet that the problem is fully addressed.
Summary:
- Address numerous reports of refcount underflows in NFSD's filecache
- Address a UAF in callback setup error handling
- Address a UAF during server-to-server copy"

cifs: fix refresh of cached referrals
We can't rely on cifs_tcon::ses to refresh cached referral as the server target might not respond to referrals, e.g. share is not hosted in a DFS root server. Consider the following mount //dom/dfs/link -> /root1/dfs/link -> /fs0/share where fs0 can't get a referral for "/root1/dfs/link". To simplify and fix the access of dfs root sessions, store the dfs root session pointer directly to new sessions so making it easier to select the appropriate ipc connection and use it for failover or cache refresh.

cifs: reduce roundtrips on create/qinfo requests
To work around some Window servers that return STATUS_OBJECT_NAME_INVALID on query infos under DFS namespaces that contain non-ASCII characters, we started checking for -ENOENT on every file open, and if so, then send additional requests to figure out whether it is a DFS link or not. It means that all those requests will be sent to every non-existing file. So, in order to reduce the number of roundtrips, check earlier whether status code is STATUS_OBJECT_NAME_INVALID and tcon supports dfs, and if so, then map -ENOENT to -EREMOTE so mount or automount will take care of chasing the DFS link -- if it isn't an DFS link, then -ENOENT will be returned appropriately.

Driver Core changes for 6.2-rc1
Here is the set of driver core and kernfs changes for 6.2-rc1. The "big" change in here is the addition of a new macro, container_of_const() that will preserve the "const-ness" of a pointer passed into it. The "problem" of the current container_of() macro is that if you pass in a "const *", out of it can comes a non-const pointer unless you specifically ask for it. For many usages, we want to preserve the "const" attribute by using the same call. For a specific example, this series changes the kobj_to_dev() macro to use it, allowing it to be used no matter what the const value is. This prevents every subsystem from having to declare 2 different individual macros (i.e. kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce the const value at build time, which having 2 macros would not do either. The driver for all of this have been discussions with the Rust kernel developers as to how to properly mark driver core, and kobject, objects as being "non-mutable". The changes to the kobject and driver core in this pull request are the result of that, as there are lots of paths where kobjects and device pointers are not modified at all, so marking them as "const" allows the compiler to enforce this. So, a nice side affect of the Rust development effort has been already to clean up the driver core code to be more obvious about object rules. All of this has been bike-shedded in quite a lot of detail on lkml with different names and implementations resulting in the tiny version we have in here, much better than my original proposal. Lots of subsystem maintainers have acked the changes as well. Other than this change, included in here are smaller stuff like: - kernfs fixes and updates to handle lock contention better - vmlinux.lds.h fixes and updates - sysfs and debugfs documentation updates - device property updates All of these have been in the linux-next tree for quite a while with no problems, OTHER than some merge issues with other trees that should be obvious when you hit them (block tree deletes a driver that this tree modifies, iommufd tree modifies code that this tree also touches).

ARM64:
* Enable the per-vcpu dirty-ring tracking mechanism, together with an option to keep the good old dirty log around for pages that are dirtied by something other than a vcpu. * Switch to the relaxed parallel fault handling, using RCU to delay page table reclaim and giving better performance under load. * Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option, which multi-process VMMs such as crosvm rely on (see merge commit |

btrfs: fix leak of fs devices after removing btrfs module
When removing the btrfs module we are not calling btrfs_cleanup_fs_uuids()
which results in leaking btrfs_fs_devices structures and other resources.
This is a regression recently introduced by a refactoring of the module
initialization and exit sequence, which simply removed the call to
btrfs_cleanup_fs_uuids() in the exit path, resulting in the leaks.
So fix this by calling btrfs_cleanup_fs_uuids() at exit_btrfs_fs().

btrfs: fix an error handling path in btrfs_defrag_leaves()
All error handling paths end to 'out', except this memory allocation
failure.
This is spurious. So branch to the error handling path also in this case.
It will add a call to:
memset(&root->defrag_progress, 0,
sizeof(root->defrag_progress));

pstore: Switch pmsg_lock to an rt_mutex to avoid priority inversion
Wei Wang reported seeing priority inversion caused latencies
caused by contention on pmsg_lock, and suggested it be switched
to a rt_mutex.
I was initially hesitant this would help, as the tasks in that
trace all seemed to be SCHED_NORMAL, so the benefit would be
limited to only nice boosting.
However, another similar issue was raised where the priority
inversion was seen did involve a blocked RT task so it is clear
this would be helpful in that case.

f2fs-for-6.2-rc1
In this round, we've added two features: 1) F2FS_IOC_START_ATOMIC_REPLACE and 2) per-block age-based extent cache. 1) is a variant of the previous atomic write feature which guarantees a per-file atomicity. It would be more efficient than AtomicFile implementation in Android framework. 2) implements another type of extent cache in memory which keeps the per-block age in a file, so that block allocator could split the hot and cold data blocks more accurately. Enhancement: - introduce F2FS_IOC_START_ATOMIC_REPLACE - refactor extent_cache to add a new per-block-age-based extent cache support - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs - add proc entry to show discard_plist info - optimize iteration over sparse directories - add barrier mount option Bug fix - avoid victim selection from previous victim section - fix to enable compress for newly created file if extension matches - set zstd compress level correctly - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot - correct i_size change for atomic writes - allow to read node block after shutdown - allow to set compression for inlined file - fix gc mode when gc_urgent_high_remaining is 1 - should put a page when checking the summary info Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmOaTNUACgkQQBSofoJI UNIQnw//V7Q8DUHw5YNj04jutwXH2DNMLAmn/NJh5S6dIzy/LiywlSzVg53/0/FP 4K577urUkIhgilRO+yncUMSnSQk7BluQvGSx4ja2AV+dpDomjxM3GwIacGzSvr7D VfVf8Vig10UEFrrtEEKtv1VFlYHAmo8lLpubzrZHV8aZFLHHYO2fakQhPu8BYsaz eGCJwxjvTZcQUPkaeG9tWto3ChI3F6PzreiQ5TztHhLWSEgw/o0qijpsc+2SthaV my7uGjeBY8EGPeSYbeCxRtdx8g8Qu11K3ISuDj8zBybmjG3IWOGt1CVcrY6tZbal aL70CMtHkMqMn03VqbpCTqBtdWNMrrw5sYSL3qXIUdXlX/2yJBh9fLAeNxKNs5Nu 6veSb2WgYMHqIsClkAAcP0xJ8g6kodGoG60wVr4ek0Vdt4osaQqwq+bnffpwwxtQ F+7aRuinv+rdrHJ4CuFXAmHPKh2lBe2lTTWZEKg2RptTxZ5DhD2Qn6x1khPD2GFA mG2Aeiq6PVxxEeIO+w/VBCuAgpGTFV2N/ZIF8VfjFNdWiN5OGLWQNHC2KGj2G2uV +fA+B91txQWtjY9h72YJb2+aGIixcnLY24ni4mDgDItqtpCB4PW56W8cbnbv9Pl+ aXAWdADqJdDyllHoVB/JQ24gr2fATJGRIDeYDnw+vPP4f5ZT5vg= =f00t -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6.2-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 two features: F2FS_IOC_START_ATOMIC_REPLACE and a per-block age-based extent cache.

hardening updates for v6.2-rc1
- Convert flexible array members, fix -Wstringop-overflow warnings,
and fix KCFI function type mismatches that went ignored by
maintainers (Gustavo A. R. Silva, Nathan Chancellor, Kees Cook).
- Remove the remaining side-effect users of ksize() by converting
dma-buf, btrfs, and coredump to using kmalloc_size_roundup(),
add more __alloc_size attributes, and introduce full testing
of all allocator functions. Finally remove the ksize() side-effect
so that each allocation-aware checker can finally behave without
exceptions.
- Introduce oops_limit (default 10,000) and warn_limit (default off)
to provide greater granularity of control for panic_on_oops and
panic_on_warn (Jann Horn, Kees Cook).
- Introduce overflows_type() and castable_to_type() helpers for
cleaner overflow checking.
- Improve code generation for strscpy() and update str*() kern-doc.
- Convert strscpy and sigphash tests to KUnit, and expand memcpy
tests.
- Always use a non-NULL argument for prepare_kernel_cred().
- Disable structleak plugin in FORTIFY KUnit test (Anders Roxell).
- Adjust orphan linker section checking to respect CONFIG_WERROR
(Xin Li).
- Make sure siginfo is cleared for forced SIGKILL (haifeng.xu).
- Fix um vs FORTIFY warnings for always-NULL arguments.

- Fix a broken error return in xfs_remove
- Print FS UUID at mount/unmount time
- Numerous fixes to the online fsck code
- Fix inode locking inconsistency problems when dealing with realtime
metadata files
- Actually merge pull requests so that we capture the cover letter
contents
- Fix a race between rebuilding VFS inode state and the AIL flushing
inodes that could cause corrupt inodes to be written to the
filesystem

unwritten extent racing with writeback started on behalf of memory
reclaim changing the extent state

adjustment code not handling MAXREFCOUNT correctly, resulting in
unnecessary record splits

Pull XFS updates from Darrick Wong:
"The highlight of this is a batch of fixes for the online metadata
checking code as we start the loooong march towards merging online
repair. I aim to merge that in time for the 2023 LTS.
There are also a large number of data corruption and race condition
fixes in this patchset. Most notably fixed are write() calls to
unwritten extents racing with writeback, which required some late(r
than I prefer) code changes to iomap to support the necessary
revalidations. I don't really like iomap changes going in past -rc4,
but Dave and I have been working on it long enough that I chose to
push it for 6.2 anyway.
There are also a number of other subtle problems fixed, including the
log racing with inode writeback to write inodes with incorrect link
count to disk; file data mapping corruptions as a result of incorrect
lock cycling when attaching dquots; refcount metadata corruption if
one actually manages to share a block 2^32 times; and the log
clobbering cow staging extents if they were formerly metadata blocks.
Summary:
- Fix a race condition w.r.t. percpu inode free counters
- Fix a broken error return in xfs_remove
- Print FS UUID at mount/unmount time
- Numerous fixes to the online fsck code
- Fix inode locking inconsistency problems when dealing with realtime

NFSD: fix use-after-free in __nfs42_ssc_open()
Problem caused by source's vfsmount being unmounted but remains on the delayed unmount list. This happens when nfs42_ssc_open() return errors. Fixed by removing nfsd4_interssc_connect(), leave the vfsmount for the laundromat to unmount when idle time expires. We don't need to call nfs_do_sb_deactive when nfs42_ssc_open return errors since the file was not opened so nfs_server->active was not incremented. Same as in nfsd4_copy, if we fail to launch nfsd4_do_async_copy thread then there's no need to call nfs_do_sb_deactive Reported-by: Xingyuan Mo <hdthky0@gmail.com> Signed-off-by: Dai Ngo <dai.ngo@oracle.com> Tested-by: Xingyuan Mo <hdthky0@gmail.com> Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |

EFI updates for v6.2:
- Refactor the zboot code so that it incorporates all the EFI stub
logic, rather than calling the decompressed kernel as a EFI app.
- Add support for initrd= command line option to x86 mixed mode.
- Allow initrd= to be used with arbitrary EFI accessible file systems
instead of just the one the kernel itself was loaded from.
- Move some x86-only handling and manipulation of the EFI memory map
into arch/x86, as it is not used anywhere else.
- More flexible handling of any random seeds provided by the boot
environment (i.e., systemd-boot) so that it becomes available much
earlier during the boot.
- Allow improved arch-agnostic EFI support in loaders, by setting a
uniform baseline of supported features, and adding a generic magic
number to the DOS/PE header. This should allow loaders such as GRUB or
systemd-boot to reduce the amount of arch-specific handling
substantially.
- (arm64) Run EFI runtime services from a dedicated stack, and use it to
recover from synchronous exceptions that might occur in the firmware
code.
- (arm64) Ensure that we don't allocate memory outside of the 48-bit
addressable physical range.
- Make EFI pstore record size configurable
- Add support for decoding CXL specific CPER records

Previously, this would have resulted in repeated multishot notifications if we had a dependency there. That could happen if an eventfd was registered as the ring eventfd, and we multishot polled for events on it. Or if an io_uring fd was added to epoll, and io_uring had a multishot request for the epoll fd.
