When CRYPTO_LIB_POLY1305 is unset, CRYPTO_LIB_POLY1305_RSIZE
is still set in the Kconfig, cluttering things.
Fix this by making CRYPTO_LIB_POLY1305_RSIZE depend on
CRYPTO_LIB_POLY1305.

Fix the arm64 build error which was caused by commit ae07562909f3 ("mm:
change huge_ptep_clear_flush() to return the original pte") interacting
with commit fb396bb459c1 ("arm64/hugetlb: Drop TLB flush from
get_clear_flush()"):
arch/arm64/mm/hugetlbpage.c: In function ‘huge_ptep_clear_flush’:
arch/arm64/mm/hugetlbpage.c:515:9: error: implicit declaration of function ‘get_clear_flush’; did you mean ‘ptep_clear_flush’? [-Werror=implicit-function-declaration]
515 | return get_clear_flush(vma->vm_mm, addr, ptep, pgsize, ncontig);
| ^~~~~~~~~~~~~~~
| ptep_clear_flush
Due to the new get_clear_contig() has dropped TLB flush, we should add
an explicit TLB flush in huge_ptep_clear_flush() to keep original
semantics when changing to use new get_clear_contig().

pipe_resize_ring() needs to take the pipe->rd_wait.lock spinlock to
prevent post_one_notification() from trying to insert into the ring
whilst the ring is being replaced.
The occupancy check must be done after the lock is taken, and the lock
must be taken after the new ring is allocated.
The bug can lead to an oops looking something like:

Pull device mapper updates from Mike Snitzer:
- Enable DM core bioset's per-cpu bio cache if QUEUE_FLAG_POLL set.
This change improves DM's hipri bio polling (REQ_POLLED) performance
by 7 - 20% depending on the system.
- Update DM core to use jump_labels to further reduce cost of unlikely
branches for zoned block devices, dm-stats and swap_bios throttling.
- Various DM core changes to reduce bio-based DM overhead and simplify
IO accounting.
- Fundamental DM core improvements to dm_io reference counting and the
elimination of using bio_split()+bio_chain() -- instead DM's
bio-based IO accounting is updated to account that a split occurred.
- Improve DM core's abnormal bio processing to do less work.
- Improve DM core's hipri polling support to use a single list rather
than an hlist.
- Update DM core to pass NULL bdev to bio_alloc_clone() so that
initialization that isn't useful for DM can be elided.
- Add cond_resched to DM stats' various loops that loop over all
entries.
- Fix incorrect error code return from DM integrity's constructor.
- Make DM crypt's printing of the key constant-time.
- Update bio-based DM multipath to provide high-resolution timer to the
Historical Service Time (HST) path selector.

Pull nfsd updates from Chuck Lever:
"We introduce 'courteous server' in this release. Previously NFSD would
purge open and lock state for an unresponsive client after one lease
period (typically 90 seconds). Now, after one lease period, another
client can open and lock those files and the unresponsive client's
lease is purged; otherwise if the unresponsive client's open and lock
state is uncontended, the server retains that open and lock state for
up to 24 hours, allowing the client's workload to resume after a
lengthy network partition.
A longstanding issue with NFSv4 file creation is also addressed.
Previously a file creation can fail internally, returning an error to
the client, but leave the newly created file in place as an artifact.
The file creation code path has been reorganized so that internal
failures and race conditions are less likely to result in an unwanted
file creation.
A fault injector has been added to help exercise paths that are run
during kernel metadata cache invalidation. These caches contain
information maintained by user space about exported filesystems. Many
of our test workloads do not trigger cache invalidation.
There is one patch that is needed to support PREEMPT_RT and a fix for
an ancient 'sleep while spin-locked' splat that seems to have become
easier to hit since v5.18-rc3"

Pull modules updates from Luis Chamberlain:
- It was time to tidy up kernel/module.c and one way of starting with
that effort was to split it up into files. At my request Aaron Tomlin
spearheaded that effort with the goal to not introduce any functional
at all during that endeavour. The penalty for the split is +1322
bytes total, +112 bytes in data, +1210 bytes in text while bss is
unchanged. One of the benefits of this other than helping make the
code easier to read and review is summoning more help on review for
changes with livepatching so kernel/module/livepatch.c is now pegged
as maintained by the live patching folks.
The before and after with just the move on a defconfig on x86-64:
$ size kernel/module.o
text data bss dec hex filename
38434 4540 104 43078 a846 kernel/module.o
$ size -t kernel/module/*.o
text data bss dec hex filename
4785 120 0 4905 1329 kernel/module/kallsyms.o
28577 4416 104 33097 8149 kernel/module/main.o
1158 8 0 1166 48e kernel/module/procfs.o
902 108 0 1010 3f2 kernel/module/strict_rwx.o
3390 0 0 3390 d3e kernel/module/sysfs.o
832 0 0 832 340 kernel/module/tree_lookup.o
39644 4652 104 44400 ad70 (TOTALS)
- Aaron added module unload taint tracking (MODULE_UNLOAD_TAINT_TRACKING),
to enable tracking unloaded modules which did taint the kernel.
- Christophe Leroy added CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOC
which lets architectures to request having modules data in vmalloc
area instead of module area. There are three reasons why an
architecture might want this:
a) On some architectures (like book3s/32) it is not possible to
protect against execution on a page basis. The exec stuff can be
mapped by different arch segment sizes (on book3s/32 that is 256M
segments). By default the module area is in an Exec segment while
vmalloc area is in a NoExec segment. Using vmalloc lets you muck
with module data as NoExec on those architectures whereas before
you could not.
b) By pushing more module data to vmalloc you also increase the
probability of module text to remain within a closer distance
from kernel core text and this reduces trampolines, this has been
reported on arm first and powerpc folks are following that lead.
c) Free'ing module_alloc() (Exec by default) area leaves this
exposed as Exec by default, some architectures have some security
enhancements to set this as NoExec on free, and splitting module
data with text let's future generic special allocators be added
to the kernel without having developers try to grok the tribal
knowledge per arch. Work like Rick Edgecombe's permission vmalloc
interface [0] becomes easier to address over time.

Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
"This series has been 12 years in the making, it mostly finishes the
work that was started with the founding of Linaro to clean up platform
support in the kernel.
The largest change here is a cleanup of the omap1 platform, which is
the final ARM machine type to get converted to the common-clk
subsystem. All the omap1 specific drivers are now made independent of
the mach/*.h headers to allow the platform to be part of a generic
ARMv4/v5 multiplatform kernel.
The last bit that enables this support is still missing here while we
wait for some last dependencies to make it into the mainline kernel
through other subsystems.
The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
at the point of allowing multiplatform kernels, this work gets
completed here along with a few additional cleanup. At the same time,
the s3c24xx and s3c64xx are now deprecated and expected to get removed
in the future.
The PXA and OMAP1 bits are in a separate branch because of
dependencies. Once both branches are merged, only the three Intel
StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100)
need separate kernels, and there are no plans to include these"

nfsd4_release_lockowner() holds clp->cl_lock when it calls
check_for_locks(). However, check_for_locks() calls nfsd_file_get()
/ nfsd_file_put() to access the backing inode's flc_posix list, and
nfsd_file_put() can sleep if the inode was recently removed.
Let's instead rely on the stateowner's reference count to gate
whether the release is permitted. This should be a reliable
indication of locks-in-use since file lock operations and
->lm_get_owner take appropriate references, which are released
appropriately when file locks are removed.

Pull xfs updates from Dave Chinner:
"This is a big update with lots of new code. The summary below them
all, so I'll just touch on teh higlights. The two main new features
are Large Extent Counts and Logged Attribute Replay - these are two
new foundational features that we are building more complex future
features on top of.
For upcoming functionality, we need to be able to store hundreds of
millions of xattrs per inode. The Large Extent Count feature removes
the limits that prevent this scale of xattr storage, and while we were
modifying the on disk extent count format we also increased the number
of data extents we support per inode from 2^32 to 2^47.
We also need to be able to modify xattrs as part of larger atomic
transactions rather than as standalone transactions. The Logged
Attribute Replay feature introduces the infrastructure that allows us
to use intents to record the attribute modifications in the journal
before we start them, hence allowing other atomic transactions to log
attribute modification intents and then defer the actual modification
to later. If we then crash, log recovery then guarantees that the
attribute is replayed in the context of the atomic transaction that
logged the intent.
A significant chunk of the commits in this merge are for the base
attribute replay functionality along with fixes, improvements and
cleanups related to this new functioanlity. Allison deserves a big
round of thanks for her ongoing work to get this functionality into
XFS.
There are also many other smaller changes and improvements, so overall
this is one of the bigger XFS merge requests in some time.
I will be following up next week with another smaller pull request -
we already have another round of fixes and improvements to the logged
attribute replay functionality just about ready to go. They'll soak
and test over the next week, and I'll send a pull request for them
near the end of the merge window.
Summary:
- support for printk message indexing.
- large extent counts to provide support for up to 2^47 data extents
and 2^32 attribute extents, allowing us to scale beyond 4 billion
data extents to billions of xattrs per inode.
- conversion of various flags fields to be consistently declared as
unsigned bit fields.
- improvements to realtime extent accounting and converts them to
per-cpu counters to match all the other block and inode accounting.
- reworks core log formatting code to reduce iterations, have a
shorter, cleaner fast path and generally be easier to understand
and maintain.
- improvements to rmap btree searches that reduce overhead by up to
30% resulting in xfs_scrub runtime reductions of 15%.
- improvements to reflink that remove the size limitations in
remapping operations and greatly reduce the size of transaction
reservations.
- reworks the minimum log size calculations to allow us to change
transaction reservations without changing the minimum supported log
size.
- removal of quota warning support as it has never been used on
Linux.
- intent whiteouts to allow us to cancel intents that are completed
entirely in memory rather than having use CPU and disk bandwidth
formatting and writing them into the journal when it is not
necessary. This makes rmap, reflink and extent freeing slightly
more efficient, but provides massive improvements for....
- Logged Attribute Replay feature support. This is a fundamental
change to the way we modify attributes, laying the foundation for
future integration of attribute modifications as part of other
atomic transactional operations the filesystem performs.
- Lots of cleanups and fixes for the logged attribute replay
functionality"

"The biggest part of this is support for fsnotify inode marks that
don't pin inodes in memory but rather get evicted together with the

In __sanitizer_cov_trace_pc(), previously we write pc before updating pos.
However, some early interrupt code could bypass check_kcov_mode() check
and invoke __sanitizer_cov_trace_pc(). If such interrupt is raised
between writing pc and updating pos, the pc could be overitten by the
recursive __sanitizer_cov_trace_pc().
As suggested by Dmitry, we cold update pos before writing pc to avoid such
interleaving.
Apply the same change to write_comp_data().

When user_dlm_destroy_lock failed, it didn't clean up the flags it set
before exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of
lock is still in used, next time when unlink invokes this function, it
will return succeed, and then unlink will remove inode and dentry if lock
is not in used(file closed), but the dlm lock is still linked in dlm lock
resource, then when bast come in, it will trigger a panic due to
user-after-free. See the following panic call trace. To fix this,
USER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should
be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink
fail.
For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN,
USER_LOCK_BUSY is also required to be cleared. Even though spin lock is
released in between, but USER_LOCK_IN_TEARDOWN is still set, for
USER_LOCK_BUSY, if before every place that waits on this flag,
USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow
waits on the busy flag set by user_dlm_destroy_lock(), then we can
simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails. Fix
user_dlm_cluster_lock() which is the only function not following this.

The following function is the only place that checks USER_LOCK_ATTACHED.
This flag is set when lock request is granted through user_ast() and only
the following function will clear it.
Checking of this flag here is to make sure ocfs2_dlm_unlock is not issued
if this lock is never granted. For example, lock file is created and then
get removed, open file never happens.
Clearing the flag here is not necessary because this is the only function
that checks it, if another flow is executing user_dlm_destroy_lock(), it
will bail out at the beginning because of USER_LOCK_IN_TEARDOWN and never
check USER_LOCK_ATTACHED. Drop the clear, so we don't need take care of
it for the following error handling patch.
int user_dlm_destroy_lock(struct user_lock_res *lockres)
{
...
status = 0;
if (!(lockres->l_flags & USER_LOCK_ATTACHED)) {
spin_unlock(&lockres->l_lock);
goto bail;
}
lockres->l_flags &= ~USER_LOCK_ATTACHED;
lockres->l_flags |= USER_LOCK_BUSY;
spin_unlock(&lockres->l_lock);
status = ocfs2_dlm_unlock(conn, &lockres->l_lksb, DLM_LKF_VALBLK);
if (status) {
user_log_dlm_error("ocfs2_dlm_unlock", status, lockres);
goto bail;
}
...
}

Pull networking updates from Jakub Kicinski:
"Core
----
- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.
- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).
- Continue work annotating skb drop reasons.
- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.
- Add VLAN support for AF_PACKET SOCK_RAW GSO.
- Allow receiving skb mark from the socket as a cmsg.
- Enable memcg accounting for veth queues, sysctl tables and IPv6.
BPF
---
- Add libbpf support for User Statically-Defined Tracing (USDTs).
- Speed up symbol resolution for kprobes multi-link attachments.
- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.
- Add support for BPF link iterator.
- Introduce access to remote CPU map elements in BPF per-cpu map.
- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.
- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.
Protocols
---------
- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding to
very popular ports (e.g. 443).
- Add bridge FDB bulk flush filtering support allowing user space to
remove all FDB entries matching a condition.
- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.
- Support for MPTCP path manager in user space.
- Add MPTCP support for fallback to regular TCP for connections that
have never connected additional subflows or transmitted
out-of-sequence data (partial support for RFC8684 fallback).
- Avoid races in MPTCP-level window tracking, stabilize and improve
throughput.
- Support lockless operation of GRE tunnels with seq numbers enabled.
- WiFi support for host based BSS color collision detection.
- Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.
- Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).
- Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).
- Allow matching on the number of VLAN tags via tc-flower.
- Add tracepoint for tcp_set_ca_state().
Driver API
----------
- Improve error reporting from classifier and action offload.
- Add support for listing line cards in switches (devlink).
- Add helpers for reporting page pool statistics with ethtool -S.
- Add support for reading clock cycles when using PTP virtual clocks,
instead of having the driver convert to time before reporting. This
makes it possible to report time from different vclocks.
- Support configuring low-latency Tx descriptor push via ethtool.
- Separate Clause 22 and Clause 45 MDIO accesses more explicitly.
New hardware / drivers
----------------------
- Ethernet:
- Marvell's Octeon NIC PCI Endpoint support (octeon_ep)
- Sunplus SP7021 SoC (sp7021_emac)
- Add support for Renesas RZ/V2M (in ravb)
