2021-08-31octeontx2-af: Set proper errorcode for IPv4 checksum errorsSunil Goutham
With current config, for packets with IPv4 checksum errors, errorcode is being set to UNKNOWN. Hence added a separate errorcodes for outer and inner IPv4 checksum and changed NPC configuration accordingly. Also turn on L2 multicast address check in NPC protocol check block.

In npc_update_vf_flow_entry function the loop cursor 'index' is being changed inside the loop causing the loop to spin forever. This in turn hogs the kworker thread forever and no other mbox message is processed by AF driver after that. Fix this by using another variable in the loop.

2021-08-31dpaa2-eth: Replace strlcpy with strscpyJason Wang
The strlcpy should not be used because it doesn't limit the source length. As linus says, it's a completely useless function if you can't implicitly trust the source string - but that is almost always why people think they should use it! All in all the BSD function will lead some potential bugs. But the strscpy doesn't require reading memory from the src string beyond the specified "count" bytes, and since the return value is easier to error-check than strlcpy()'s. In addition, the implementation is robust to the string changing out from underneath it, unlike the current strlcpy() implementation. Thus, We prefer using strscpy instead of strlcpy.

Commit 76c47d1449fc ("gpio: mpc8xxx: Add ACPI support") has switched to a managed version when dealing with 'mpc8xxx_gc->regs'. So the corresponding 'iounmap()' call in the error handling path and in the remove should be removed to avoid a double unmap. This also allows some simplification in the probe. All the error handling paths related to managed resources can be direct returns and a NULL check in what remains in the error handling path can be removed.

2021-08-31drm/ttm: Fix ttm_bo_move_memcpy() for subclassed struct ttm_resourceThomas Hellström
The code was making a copy of a struct ttm_resource. However, recently the struct ttm_resources were allowed to be subclassed and also were allowed to be malloced, hence the driver could end up assuming the copy we handed it was subclassed and worse, the original could have been freed at this point. Fix this by using the original struct ttm_resource before it is potentially freed in ttm_bo_move_sync_cleanup() v2: Base on drm-misc-next-fixes rather than drm-tip.

2021-08-30sch_htb: Fix inconsistency when leaf qdisc creation failsMaxim Mikityanskiy
In HTB offload mode, qdiscs of leaf classes are grafted to netdev queues. sch_htb expects the dev_queue field of these qdiscs to point to the corresponding queues. However, qdisc creation may fail, and in that case noop_qdisc is used instead. Its dev_queue doesn't point to the right queue, so sch_htb can lose track of used netdev queues, which will cause internal inconsistencies. This commit fixes this bug by keeping track of the netdev queue inside struct htb_class. All reads of cl->leaf.q->dev_queue are replaced by the new field, the two values are synced on writes, and WARNs are added to assert equality of the two values. The driver API has changed: when TC_HTB_LEAF_DEL needs to move a queue, the driver used to pass the old and new queue IDs to sch_htb. Now that there is a new field (offload_queue) in struct htb_class that needs to be updated on this operation, the driver will pass the old class ID to sch_htb instead (it already knows the new class ID).

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" * tag 'locking-core-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (92 commits) locking/rtmutex: Return success on deadlock for ww_mutex waiters locking/rtmutex: Prevent spurious EDEADLK return caused by ww_mutexes locking/rtmutex: Dequeue waiter on ww_mutex deadlock locking/rtmutex: Dont dereference waiter lockless locking/semaphore: Add might_sleep() to down_*() family locking/ww_mutex: Initialize waiter.ww_ctx properly static_call: Update API documentation locking/local_lock: Add PREEMPT_RT support locking/spinlock/rt: Prepare for RT local_lock locking/rtmutex: Add adaptive spinwait mechanism locking/rtmutex: Implement equal priority lock stealing preempt: Adjust PREEMPT_LOCK_OFFSET for RT locking/rtmutex: Prevent lockdep false positive with PI futexes futex: Prevent requeue_pi() lock nesting issue on RT futex: Simplify handle_early_requeue_pi_wakeup() futex: Reorder sanity checks in futex_requeue() futex: Clarify comment in futex_requeue() futex: Restructure futex_requeue() futex: Correct the number of requeued waiters for PI futex: Remove bogus condition for requeue PI ...

2021-08-30drm/amd/pm: And destination bounds checking to struct copyKees Cook
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. The "Board Parameters" members of the structs: struct atom_smc_dpm_info_v4_5 struct atom_smc_dpm_info_v4_6 struct atom_smc_dpm_info_v4_7 struct atom_smc_dpm_info_v4_10 are written to the corresponding members of the corresponding PPTable_t variables, but they lack destination size bounds checking, which means the compiler cannot verify at compile time that this is an intended and safe memcpy(). Since the header files are effectively immutable[1] and a struct_group() cannot be used, nor a common struct referenced by both sides of the memcpy() arguments, add a new helper, amdgpu_memcpy_trailing(), to perform the bounds checking at compile time. Replace the open-coded memcpy()s with amdgpu_memcpy_trailing() which includes enough context for the bounds checking. "objdump -d" shows no object code changes.
