ksmbd: add missing assignments to ret on ndr_read_int64 read calls
Currently there are two ndr_read_int64 calls where ret is being checked
for failure but ret is not being assigned a return value from the call.
Static analyis is reporting the checks on ret as dead code. Fix this.

ksmbd: defer notify_change() call
When ownership is changed we might in certain scenarios loose the ability to alter the inode after we changed ownership. This can e.g. happen when we are on an idmapped mount where uid 0 is mapped to uid 1000 and uid 1000 is mapped to uid 0. A caller with fs*id 1000 will be able to create files as *id 1000 on disk. They will also be able to change ownership of files owned by *id 0 to *id 1000 but they won't be able to change ownership in the other direction. This means acl operations following notify_change() would fail. Move the notify_change() call after the acls have been updated. This guarantees that we don't end up with spurious "hash value diff" warnings later on because we managed to change ownership but didn't manage to alter acls.

ksmbd: remove setattr preparations in set_file_basic_info()
Permission checking and copying over ownership information is the task of the underlying filesystem not ksmbd. The order is also wrong here. This modifies the inode before notify_change(). If notify_change() fails this will have changed ownership nonetheless. All of this is unnecessary though since the underlying filesystem's ->setattr handler will do all this (if required) by itself.

ndr: fix translation in ndr_encode_posix_acl()
The sid_to_id() helper encodes raw ownership information suitable for s*id handling. This is conceptually equivalent to reporting ownership information via stat to userspace. In this case the consumer is ksmbd instead of a regular user. So when encoding raw ownership information suitable for s*id handling later we need to map the id up according to the user namespace of ksmbd itself taking any idmapped mounts into account.

ksmbd: fix translation in sid_to_id()
The sid_to_id() functions is relevant when changing ownership of filesystem objects based on acl information. In this case we need to first translate the relevant s*ids into k*ids in ksmbd's user namespace and account for any idmapped mounts. Requesting a change in ownership requires the inverse translation to be applied when we would report ownership to userspace. So k*id_from_mnt() must be used here.

ksmbd: fix translation in acl entries
The ksmbd server performs translation of posix acls to smb acls. Currently the translation is wrong since the idmapping of the mount is used to map the ids into raw userspace ids but what is relevant is the user namespace of ksmbd itself. The user namespace of ksmbd itself which is the initial user namespace. The operation is similar to asking "What *ids would a userspace process see given that k*id in the relevant user namespace?". Before the final translation we need to apply the idmapping of the mount in case any is used. Add two simple helpers for ksmbd.

ksmbd: fix translation in ksmbd_acls_fattr()
When creating new filesystem objects ksmbd translates between k*ids and s*ids. For this it often uses struct smb_fattr and stashes the k*ids in cf_uid and cf_gid. Let cf_uid and cf_gid always contain the final information taking any potential idmapped mounts into account. When finally translation cf_*id into s*ids translate them into the user namespace of ksmbd since that is the relevant user namespace here.

ksmbd: fix translation in create_posix_rsp_buf()
When transferring ownership information to the client the k*ids are translated into raw *ids before they are sent over the wire. The function currently erroneously translates the k*ids according to the mount's idmapping. Instead, reporting the owning *ids to userspace the underlying k*ids need to be mapped up in the caller's user namespace. This is how stat() works. The caller in this instance is ksmbd itself and ksmbd always runs in the initial user namespace. Translate according to that taking any potential idmapped mounts into account. Switch to from_k*id_munged() which ensures that the overflow*id is returned instead of the (*id_t)-1 when the k*id can't be translated.

ksmbd: fix lookup on idmapped mounts
It's great that the new in-kernel ksmbd server will support idmapped
mounts out of the box! However, lookup is currently broken. Lookup
helpers such as lookup_one_len() call inode_permission() internally to
ensure that the caller is privileged over the inode of the base dentry
they are trying to lookup under. So the permission checking here is
currently wrong.
Linux v5.15 will gain a new lookup helper lookup_one() that does take
idmappings into account. I've added it as part of my patch series to
make btrfs support idmapped mounts. The new helper is in linux-next as
part of David's (Sterba) btrfs for-next branch as commit
c972214c133b ("namei: add mapping aware lookup helper").
I've said it before during one of my first reviews: I would very much
recommend adding fstests to [1]. It already seems to have very
rudimentary cifs support. There is a completely generic idmapped mount
testsuite that supports idmapped mounts.

Merge tag '5.15-rc-first-ksmbd-merge' of git://git.samba.org/ksmbd
Pull initial ksmbd implementation from Steve French:
"Initial merge of kernel smb3 file server, ksmbd.
The SMB family of protocols is the most widely deployed network
filesystem protocol, the default on Windows and Macs (and even on many
phones and tablets), with clients and servers on all major operating
systems, but lacked a kernel server for Linux. For many cases the
current userspace server choices were suboptimal either due to memory
footprint, performance or difficulty integrating well with advanced
Linux features.
ksmbd is a new kernel module which implements the server-side of the
SMB3 protocol. The target is to provide optimized performance, GPLv2
SMB server, and better lease handling (distributed caching). The
bigger goal is to add new features more rapidly (e.g. RDMA aka
"smbdirect", and recent encryption and signing improvements to the
protocol) which are easier to develop on a smaller, more tightly
optimized kernel server than for example in Samba.
The Samba project is much broader in scope (tools, security services,
LDAP, Active Directory Domain Controller, and a cross platform file
server for a wider variety of purposes) but the user space file server
portion of Samba has proved hard to optimize for some Linux workloads,
including for smaller devices.
This is not meant to replace Samba, but rather be an extension to
allow better optimizing for Linux, and will continue to integrate well
with Samba user space tools and libraries where appropriate. Working
with the Samba team we have already made sure that the configuration
files and xattrs are in a compatible format between the kernel and
user space server.
Various types of functional and regression tests are regularly run
against it. One example is the automated 'buildbot' regression tests
which use the Linux client to test against ksmbd, e.g.
http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/8/builds/56
but other test suites, including Samba's smbtorture functional test
suite are also used regularly"

Updates for timekeeping, timers and related drivers:
Core code:
- Cure a couple of incorrectness issues in the posix CPU timer code to
prevent that the tick dependency for NOHZ full is kept alive for no
reason.
- Avoid expensive double reprogramming of the clockevent device in
hrtimer_start_range_ns().
- Avoid pointless SMP function calls when the clock was set to avoid
disturbing CPUs which do not have any affected timers queued.
- Make the clocksource watchdog test work correctly when CONFIG_HZ is
less than 100.
Drivers:
- Prefer the ARM architected timer over the Exynos timer which is way
more expensive to access.
- Add device tree bindings for new Ingenic SoCs
- The usual improvements and cleanups all over the place

A reworked version of the opt-in L1D flush mechanism:
A stop gap for potential future speculation related hardware
vulnerabilities and a mechanism for truly security paranoid
applications.
It allows a task to request that the L1D cache is flushed when the kernel
switches to a different mm. This can be requested via prctl().
Changes vs. the previous versions:
- Get rid of the software flush fallback
- Make the handling consistent with other mitigations
- Kill the task when it ends up on a SMT enabled core which defeats the
purpose of L1D flushing obviously

Updates for locking and atomics:
The regular pile:
- A few improvements to the mutex code
- Documentation updates for atomics to clarify the difference between
cmpxchg() and try_cmpxchg() and to explain the forward progress
expectations.
- Simplification of the atomics fallback generator
- The addition of arch_atomic_long*() variants and generic arch_*()
bitops based on them.
- Add the missing might_sleep() invocations to the down*() operations of
semaphores.
The PREEMPT_RT locking core:
- Scheduler updates to support the state preserving mechanism for
'sleeping' spin- and rwlocks on RT. This mechanism is carefully
preserving the state of the task when blocking on a 'sleeping' spin- or
rwlock and takes regular wake-ups targeted at the same task into
account. The preserved or updated (via a regular wakeup) state is
restored when the lock has been acquired.
- Restructuring of the rtmutex code so it can be utilized and extended
for the RT specific lock variants.
- Restructuring of the ww_mutex code to allow sharing of the ww_mutex
specific functionality for rtmutex based ww_mutexes.
- Header file disentangling to allow substitution of the regular lock
implementations with the PREEMPT_RT variants without creating an
unmaintainable #ifdef mess.
- Shared base code for the PREEMPT_RT specific rw_semaphore and rwlock
implementations. Contrary to the regular rw_semaphores and rwlocks the
PREEMPT_RT implementation is writer unfair because it is infeasible to
do priority inheritance on multiple readers. Experience over the years
has shown that real-time workloads are not the typical workloads which
are sensitive to writer starvation. The alternative solution would be
to allow only a single reader which has been tried and discarded as it
is a major bottleneck especially for mmap_sem. Aside of that many of
the writer starvation critical usage sites have been converted to a
writer side mutex/spinlock and RCU read side protections in the past
decade so that the issue is less prominent than it used to be.
- The actual rtmutex based lock substitutions for PREEMPT_RT enabled
kernels which affect mutex, ww_mutex, rw_semaphore, spinlock_t and
rwlock_t. The spin/rw_lock*() functions disable migration across the
critical section to preserve the existing semantics vs. per CPU
variables.
- Rework of the futex REQUEUE_PI mechanism to handle the case of early
wake-ups which interleave with a re-queue operation to prevent the
situation that a task would be blocked on both the rtmutex associated
to the outer futex and the rtmutex based hash bucket spinlock.
While this situation cannot happen on !RT enabled kernels the changes
make the underlying concurrency problems easier to understand in
general. As a result the difference between !RT and RT kernels is
reduced to the handling of waiting for the critical section. !RT
kernels simply spin-wait as before and RT kernels utilize rcu_wait().
- The substitution of local_lock for PREEMPT_RT with a spinlock which
protects the critical section while staying preemptible. The CPU
locality is established by disabling migration.
The underlying concepts of this code have been in use in PREEMPT_RT for
way more than a decade. The code has been refactored several times over
the years and this final incarnation has been optimized once again to be
as non-intrusive as possible, i.e. the RT specific parts are mostly
isolated.
It has been extensively tested in the 5.14-rt patch series and it has
been verified that !RT kernels are not affected by these changes.

Scheduler changes for v5.15 are:
- The biggest change in this cycle is scheduler support for asymmetric scheduling affinity, to support the execution of legacy 32-bit tasks on AArch32 systems that also have 64-bit-only CPUs. Architectures can fill in this functionality by defining their own task_cpu_possible_mask(p). When this is done, the scheduler will make sure the task will only be scheduled on CPUs that support it. (The actual arm64 specific changes are not part of this tree.) For other architectures there will be no change in functionality. - Add cgroup SCHED_IDLE support - Increase node-distance flexibility & delay determining it until a CPU is brought online. (This enables platforms where node distance isn't final until the CPU is only.) - Deadline scheduler enhancements & fixes - Misc fixes & cleanups.

Pull RCU updates from Paul McKenney:
"RCU changes for this cycle were:
- Documentation updates
- Miscellaneous fixes
- Offloaded-callbacks updates
- Updates to the nolibc library
- Tasks-RCU updates
- In-kernel torture-test updates
- Torture-test scripting, perhaps most notably the pinning of
torture-test guest OSes so as to force differences in memory
latency. For example, in a two-socket system, a four-CPU guest OS
will have one pair of its CPUs pinned to threads in a single core
on one socket and the other pair pinned to threads in a single core
on the other socket. This approach proved able to force race
conditions that earlier testing missed. Some of these race
conditions are still being tracked down"
