[ Upstream commit 170a9e341a3b02c0b2ea0df16ef14a33a4f41de8 ]
The offset 12 (bit-rate) of EEPROM SFP DAC (passive) cables is expected
to be in the range 0x64 to 0x68. However, the 5 meter and 7 meter Molex
passive cables have the rate ceiling 0x78 at offset 12.
Add a quirk for Molex passive cables to extend the rate ceiling to 0x78.

[ Upstream commit 09c5f6bf11ac98874339e55f4f5f79a9dbc9b375 ]
The current XGBE code assumes that offset 6 of EEPROM SFP DAC (passive)
cables is NULL. However, some cables (the 5 meter and 7 meter Molex
passive cables) have non-zero data at offset 6. Fix the logic by moving
the passive cable check above the active checks, so as not to be
improperly identified as an active cable. This will fix the issue for
any passive cable that advertises 1000Base-CX in offset 6.

When a console stack dump is initiated with CONFIG_GCOV_PROFILE_ALL

This happens when the compiled code for show_stack() has a single word
on the stack, and doesn't use a tail call to show_stack_log_lvl().
(CONFIG_GCOV_PROFILE_ALL=y is the only known case of this.) Then the
__unwind_start() skip logic hits an off-by-one bug and fails to unwind
all the way to the intended starting frame.
Fix it by reverting the following commit:
f1d9a2abff66 ("x86/unwind/orc: Don't skip the first frame for inactive tasks")
The original justification for that commit no longer exists. That
original issue was later fixed in a different way, with the following
commit:

It was caused by srv->listener that might be set to null by
tipc_topsrv_stop() in net .exit whereas it's still used in
tipc_topsrv_accept() worker.
srv->listener is protected by srv->idr_lock in tipc_topsrv_stop(), so add
a check for srv->listener under srv->idr_lock in tipc_topsrv_accept() to
avoid the null-ptr-deref. To ensure the lsock is not released during the
tipc_topsrv_accept(), move sock_release() after tipc_topsrv_work_stop()
where it's waiting until the tipc_topsrv_accept worker to be done.
Note that sk_callback_lock is used to protect sk->sk_user_data instead of
srv->listener, and it should check srv in tipc_topsrv_listener_data_ready()
instead. This also ensures that no more tipc_topsrv_accept worker will be
started after tipc_conn_close() is called in tipc_topsrv_stop() where it
sets sk->sk_user_data to null.

[ Upstream commit ca6c21327c6af02b7eec31ce4b9a740a18c6c13f ]
Marco reported:
Due to the implementation of how SIGTRAP are delivered if
perf_event_attr::sigtrap is set, we've noticed 3 issues:
1. Missing SIGTRAP due to a race with event_sched_out() (more
details below).
2. Hardware PMU events being disabled due to returning 1 from
perf_event_overflow(). The only way to re-enable the event is
for user space to first "properly" disable the event and then
re-enable it.
3. The inability to automatically disable an event after a
specified number of overflows via PERF_EVENT_IOC_REFRESH.
The worst of the 3 issues is problem (1), which occurs when a
pending_disable is "consumed" by a racing event_sched_out(), observed
as follows:
CPU0 | CPU1
--------------------------------+---------------------------
__perf_event_overflow() |
perf_event_disable_inatomic() |
pending_disable = CPU0 | ...
| _perf_event_enable()
| event_function_call()
| task_function_call()
| /* sends IPI to CPU0 */
<IPI> | ...
__perf_event_enable() +---------------------------
ctx_resched()
task_ctx_sched_out()
ctx_sched_out()
group_sched_out()
event_sched_out()
pending_disable = -1
</IPI>
<IRQ-work>
perf_pending_event()
perf_pending_event_disable()
/* Fails to send SIGTRAP because no pending_disable! */
</IRQ-work>
In the above case, not only is that particular SIGTRAP missed, but also
all future SIGTRAPs because 'event_limit' is not reset back to 1.
To fix, rework pending delivery of SIGTRAP via IRQ-work by introduction
of a separate 'pending_sigtrap', no longer using 'event_limit' and
'pending_disable' for its delivery.
Additionally; and different to Marco's proposed patch:
- recognise that pending_disable effectively duplicates oncpu for
the case where it is set. As such, change the irq_work handler to
use ->oncpu to target the event and use pending_* as boolean toggles.
- observe that SIGTRAP targets the ctx->task, so the context switch
optimization that carries contexts between tasks is invalid. If
the irq_work were delayed enough to hit after a context switch the
SIGTRAP would be delivered to the wrong task.
- observe that if the event gets scheduled out
(rotation/migration/context-switch/...) the irq-work would be
insufficient to deliver the SIGTRAP when the event gets scheduled
back in (the irq-work might still be pending on the old CPU).
Therefore have event_sched_out() convert the pending sigtrap into a
task_work which will deliver the signal at return_to_user.

commit 406e14808ee695cbae1eafa5fd3ac563c29470ab upstream.
Before switching back to the right partition in mmc_blk_reset there used
to be a check if hw_reset was even supported. This return value
was removed, so there is no reason to check. Furthermore ensure
part_curr is not falsely set to a valid value on reset or
partition switch error.
As part of this change the code paths of mmc_blk_reset calls were checked
to ensure no commands are issued after a failed mmc_blk_reset directly
without going through the block layer.

commit 4fd9df10cb7a9289fbd22d669f9f98164d95a1ce upstream.
Since commit d9820ff ("ARC: mm: switch pgtable_t back to struct page *")
a memory leakage problem occurs. Memory allocated for page table entries
not released during process termination. This issue can be reproduced by
a small program that allocates a large amount of memory. After several
runs, you'll see that the amount of free memory has reduced and will
continue to reduce after each run. All ARC CPUs are effected by this
issue. The issue was introduced since the kernel stable release v5.15-rc1.
As described in commit d9820ff after switch pgtable_t back to struct
page *, a pointer to "struct page" and appropriate functions are used to
allocate and free a memory page for PTEs, but the pmd_pgtable macro hasn't
changed and returns the direct virtual address from the PMD (PGD) entry.
Than this address used as a parameter in the __pte_free() and as a result
this function couldn't release memory page allocated for PTEs.
Fix this issue by changing the pmd_pgtable macro and returning pointer to
struct page.

assuming Signal0 is requested without checking. This results in requests

callbacks and handling accordingly based on the particular Signal
requested. The trig_inverted member of the mchp_tc_data is removed as
superfluous.

commit 6746eae4bbaddcc16b40efb33dab79210828b3ce upstream.
cti_enable_hw() and cti_disable_hw() are called from an atomic context
so shouldn't use runtime PM because it can result in a sleep when
communicating with firmware.
Since commit 3c6656337852 ("Revert "firmware: arm_scmi: Add clock
management to the SCMI power domain""), this causes a hang on Juno when
running the Perf Coresight tests or running this command:
perf record -e cs_etm//u -- ls
This was also missed until the revert commit because pm_runtime_put()
was called with the wrong device until commit 692c9a499b28 ("coresight:
cti: Correct the parameter for pm_runtime_put")
With lock and scheduler debugging enabled the following is output:

commit a79343dcaba4b11adb57350e0b6426906a9b658e upstream.
Device-managed resources allocated post component bind must be tied to
the lifetime of the aggregate DRM device or they will not necessarily be
released when binding of the aggregate device is deferred.
This is specifically true for the DP IRQ, which will otherwise remain
requested so that the next bind attempt fails when requesting the IRQ a
second time.
Since commit c3bf8e21b38a ("drm/msm/dp: Add eDP support via aux_bus")
this can happen when the aux-bus panel driver has not yet been loaded so
that probe is deferred.
Fix this by tying the device-managed lifetime of the DP IRQ to the DRM
device so that it is released when bind fails.

commit 5a5c4e06fd03b595542d5590f2bc05a6b7fc5c2b upstream.
Back in 2014, the LQI was saved in the skb control buffer (skb->cb, or
mac_cb(skb)) without any actual reset of this area prior to its use.
As part of a useful rework of the use of this region, 32edc40ae65c
("ieee802154: change _cb handling slightly") introduced mac_cb_init() to
basically memset the cb field to 0. In particular, this new function got
called at the beginning of mac802154_parse_frame_start(), right before
the location where the buffer got actually filled.
What went through unnoticed however, is the fact that the very first
helper called by device drivers in the receive path already used this
area to save the LQI value for later extraction. Resetting the cb field
"so late" led to systematically zeroing the LQI.
If we consider the reset of the cb field needed, we can make it as soon
as we get an skb from a device driver, right before storing the LQI,
as is the very first time we need to write something there.
