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.

Commit 9130b8dbc6ac ("SUNRPC: allow for upcalls for the same uid
but different gss service") introduced `auth` argument to
__gss_find_upcall(), but in gss_pipe_downcall() it was left as NULL
since it (and auth->service) was not (yet) determined.
When multiple upcalls with the same uid and different service are
ongoing, it could happen that __gss_find_upcall(), which returns the
first match found in the pipe->in_downcall list, could not find the
correct gss_msg corresponding to the downcall we are looking for.
Moreover, it might return a msg which is not sent to rpc.gssd yet.
We could see mount.nfs process hung in D state with multiple mount.nfs
are executed in parallel. The call trace below is of CentOS 7.9
kernel-3.10.0-1160.24.1.el7.x86_64 but we observed the same hang w/
elrepo kernel-ml-6.0.7-1.el7.
PID: 71258 TASK: ffff91ebd4be0000 CPU: 36 COMMAND: "mount.nfs"

#9 [ffff9203ca323820] rpc_execute at ffffffffc0420a48 [sunrpc]
The scenario is like this. Let's say there are two upcalls for
services A and B, A -> B in pipe->in_downcall, B -> A in pipe->pipe.
When rpc.gssd reads pipe to get the upcall msg corresponding to
service B from pipe->pipe and then writes the response, in
gss_pipe_downcall the msg corresponding to service A will be picked
because only uid is used to find the msg and it is before the one for
B in pipe->in_downcall. And the process waiting for the msg
corresponding to service A will be woken up.
Actual scheduing of that process might be after rpc.gssd processes the
next msg. In rpc_pipe_generic_upcall it clears msg->errno (for A).
The process is scheduled to see gss_msg->ctx == NULL and
gss_msg->msg.errno == 0, therefore it cannot break the loop in
gss_create_upcall and is never woken up after that.
This patch adds a simple check to ensure that a msg which is not
sent to rpc.gssd yet is not chosen as the matching upcall upon
receiving a downcall.

940261a19508 introduced nfs_io_size() to clamp the iosize to a multiple
of PAGE_SIZE. This had the unintended side effect of no longer allowing
iosizes less than a page, which could be useful in some situations.
UDP already has an exception that causes it to fall back on the
power-of-two style sizes instead. This patch adds an additional
exception for very small iosizes.

When the NFSv4 state manager recovers state after a server restart, it
reports that locks have been lost if it finds any lock state for which
recovery hasn't been successful. i.e. any for which
NFS_LOCK_INITIALIZED is not set.
However it only tries to recover locks that are still linked to
inode->i_flctx. So if a lock has been removed from inode->i_flctx, but
the state for that lock has not yet been destroyed, then a spurious
warning results.
nfs4_proc_unlck() calls locks_lock_inode_wait() - which removes the lock
from ->i_flctx - before sending the unlock request to the server and
before the final nfs4_put_lock_state() is called. This allows a window
in which a spurious warning can be produced.
So add a new flag NFS_LOCK_UNLOCKING which is set once the decision has
been made to unlock the lock. This will prevent it from triggering any
warning.

According to commit "vfs: parse: deal with zero length string value",
kernel will set the param->string to null pointer in vfs_parse_fs_string()
if fs string has zero length.
Yet the problem is that, nfs_fs_context_parse_param() will dereferences the
param->string, without checking whether it is a null pointer, which may
trigger a null-ptr-deref bug.
This patch solves it by adding sanity check on param->string
in nfs_fs_context_parse_param().

If we're asked to recover open state while a delegation return is

delegation unless we're explicitly reclaiming one.

Since commit 1a34c8c9a49e ("NFS: Support larger readdir buffers") has
updated dtsize, and with recent improvements to the READDIRPLUS helper
heuristic, the heuristic may not trigger until many dentries are emitted
to userspace. This will cause many thousands of GETATTR calls for "ls
-l" when the directory's pagecache has already been populated. This
manifests as poor performance for long directory listings after an
initially fast "ls -l".
Fix this by emitting only 17 entries for any first pass through the NFS
directory's ->iterate_shared(), which allows userpace to prime the
counters for the heuristic.

POSIX typically only refreshes the user's supplementary group
information upon login. Since NFS servers may often refresh their
concept of the user supplementary group membership at their own cadence,
it is possible for the NFS client's access cache to become stale due to
the user's group membership changing on the server after the user has
already logged in on the client.
While it is reasonable to expect that such group membership changes are
rare, and that we do not want to optimise the cache to accommodate them,
it is also not unreasonable for the user to expect that if they log out
and log back in again, that the staleness would clear up.

Pull power management fixes from Rafael Wysocki:
"These revert a recent change in the schedutil cpufreq governor that
had not been expected to make any functional difference, but turned
out to introduce a performance regression, fix an initialization issue
in the amd-pstate driver and make it actually replace the venerable
ACPI cpufreq driver on the supported systems by default.
Specifics:
- Revert a recent schedutil cpufreq governor change that introduced a
performace regression on Pixel 6 (Sam Wu)
- Fix amd-pstate driver initialization after running the kernel via
kexec (Wyes Karny)
- Turn amd-pstate into a built-in driver which allows it to take
precedence over acpi-cpufreq by default on supported systems and
amend it with a mechanism to disable this behavior (Perry Yuan)
- Update amd-pstate documentation in accordance with the other
changes made to it (Perry Yuan)"

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Alexander Gordeev:
- Fix size of incorrectly increased from four to eight bytes TOD field
of crash dump save area. As result in case of kdump NT_S390_TODPREG
ELF notes section contains correct value and "detected read beyond
size of field" compiler warning goes away.
- Fix memory leak in cryptographic Adjunct Processors (AP) module on
initialization failure path.
- Add Gerald Schaefer <[email protected]> and Alexander
Gordeev <[email protected]> as S390 memory management
maintainers. Also rename the S390 section to S390 ARCHITECTURE to be
a bit more precise.

Pull hotfixes from Andrew Morton:
"24 MM and non-MM hotfixes. 8 marked cc:stable and 16 for post-6.0
issues.
There have been a lot of hotfixes this cycle, and this is quite a
large batch given how far we are into the -rc cycle. Presumably a
reflection of the unusually large amount of MM material which went
into 6.1-rc1"
