octeontx2-af: Set proper errorcode for IPv4 checksum errors
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.

octeontx2-af: Fix mailbox errors in nix_rss_flowkey_cfg
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.

af_unix: fix potential NULL deref in unix_dgram_connect()
syzbot was able to trigger NULL deref in unix_dgram_connect() [1]
This happens in
if (unix_peer(sk))
sk->sk_state = other->sk_state = TCP_ESTABLISHED; // crash because @other is NULL
Because locks have been dropped, unix_peer() might be non NULL,
while @other is NULL (AF_UNSPEC case)
We need to move code around, so that we no longer access
unix_peer() and sk_state while locks have been released.

dpaa2-eth: Replace strlcpy with strscpy
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.

net: bridge: use mld2r_ngrec instead of icmpv6_dataun
br_ip6_multicast_mld2_report function uses icmp6h to parse mld2_report packet. mld2r_ngrec defines mld2r_hdr.icmp6_dataun.un_data16[1] in include/net/mld.h. So, it is more compact to use mld2r rather than icmp6h. By doing printk test, it is confirmed that icmp6h->icmp6_dataun.un_data16[1] and mld2r->mld2r_ngrec are indeed equivalent. Also, sizeof(*mld2r) and sizeof(*icmp6h) are equivalent, too. Signed-off-by: MichelleJin <shjy180909@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

net: sched: Fix qdisc_rate_table refcount leak when get tcf_block failed
The reference counting issue happens in one exception handling path of
cbq_change_class(). When failing to get tcf_block, the function forgets
to decrease the refcount of "rtab" increased by qdisc_put_rtab(),
causing a refcount leak.
Fix this issue by jumping to "failure" label when get tcf_block failed.

sch_htb: Fix inconsistency when leaf qdisc creation fails
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).
Fixes:

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

which can be found on various ALi chipsets and is also available on older Intel systems which expose a PIRQ router. While the Intel support is more or less nostalgia, the ALi chips are still in use on popular embedded boards used for routers. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmEsn2QTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoQT1EACIvzRbycwclASIV6rBK5FMcVa2VuXR GVqrfERPCUHQxnLshUJxnLk0NvZcQrLHjYl/QMCHBFOeEh3XrzU7JkKDW0Q8Dnov QGFRtandKDwY4TwnCPKVdz/HeWMxNRT7OF4d08Q3iKCN5l39RLxraMixSrFL8soO wgGcRTjbTa6HaMlqacFN7DwwiHxbIGJNepi0yqLZBV2dQOnZPd+ujV1FRSNXkv9p vFPfuazk/psiSXy3x/+YVPUw+6h8DRDkflc9+wvSR+1cVl8eyrjkLgLH43ihddEN Dl1SG5vKyCOtvQm+TEYdB5qjb/Zd4BjlbvKPJ+94OTtsjIIwxzInizkeTXiLHXnl SDHX9Sc8L4sYP5+tAew1WMj8K2/p6FzdHm+sBJHd2JFSsMpeErI7p0y0Nz58E7pG 0cRqeWlq7rbGFPq544A8cgx/LjPkZT4LgutGpJ6f3NTZeLfj09xbFRqxNOHqAx+h fp+36RNb1/j70Yz+4r7lLeDOVswbK+YxPIZGdnNfINTHeGllthDI5vaUL0L2jZnI CnnKjss2a1WkDC8gczr/3QYcQRKrKDHL0hn0nUh+9laAaTSwNv3oRrkUWvMqwaT8 qSMMm5Eb84B4fZLyvPIcAwyC++JU/cVCgWEP37EzhYcvp6tq8GmR1cdi1lo2/K4O qhg1d7loNh0eCg== =R+c1 -----END PGP SIGNATURE----- Merge tag 'x86-irq-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 PIRQ updates from Thomas Gleixner: "A set of updates to support port 0x22/0x23 based PCI configuration space which can be found on various ALi chipsets and is also available on older Intel systems which expose a PIRQ router.

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"
