Move the allocation of chip->auth to tpm2_start_auth_session() so that this
field can be used as flag to tell whether auth session is active or not.
Instead of flushing and reloading the auth session for every transaction
separately, keep the session open unless /dev/tpm0 is used.

Commit 0aaa8977acbf ("configs: introduce debug.config for CI-like setup")
added CONFIG_PROVE_RCU_LIST=y to the common CI config,
but RCU_EXPERT is not set, and it's a dependency for
CONFIG_PROVE_RCU_LIST=y. Make sure CIs take advantage
of CONFIG_PROVE_RCU_LIST=y, recent fixes in networking
indicate that it does catch bugs.

That makes this perf source code to be rebuilt:
CC /tmp/build/perf-tools/util/arm-spe.o
The changes in the above patch add MIDR_NEOVERSE_N3, that probably need

maybe we need to leave this for later when this is all tested on those

"I would not touch this for now -- someone would have to go audit the

it'd be better to do that as a follow-up."

If devm_gpiod_get_optional() fails, we need to disable previously enabled
regulators, as done in the other error handling path of the function.
Also, gpiod_set_value_cansleep(, 1) needs to be called to undo a
potential gpiod_set_value_cansleep(, 0).
If the "reset" gpio is not defined, this additional call is just a no-op.
This behavior is the same as the one already in the .remove() function.

Pull ftrace fixes from Steven Rostedt:
- Fix missing mutex unlock in error path of register_ftrace_graph()
A previous fix added a return on an error path and forgot to unlock

the mutex is just released at the exit of the function anyway. Other
functions in this file should be updated with this, but that's a
cleanup and not a fix.
- Change cpuhp setup name to be consistent with other cpuhp states

In a commit 24b7f8e5cd65 ("firewire: core: use helper functions for self
ID sequence"), the enumeration over self ID sequence was refactored with
some helper functions with KUnit tests. These helper functions are
guaranteed to work expectedly by the KUnit tests, however their application
includes a mistake to assign invalid value to the index of port connected
to parent device.
This bug affects the case that any extra node devices which has three or
more ports are connected to 1394 OHCI controller. In the case, the path
to update the tree cache could hits WARN_ON(), and gets general protection
fault due to the access to invalid address computed by the invalid value.
This commit fixes the bug to assign correct port index.

ieee80211_chanctx
Move the `struct ieee80211_chanctx_conf conf` to the end of
`struct ieee80211_chanctx` and fix a memory corruption bug
triggered e.g. in `hwsim_set_chanctx_magic()`: `radar_detected`
is being overwritten when `cp->magic = HWSIM_CHANCTX_MAGIC;`
See the function call sequence below:
drv_add_chanctx(... struct ieee80211_chanctx *ctx) ->
local->ops->add_chanctx(&local->hw, &ctx->conf) ->
mac80211_hwsim_add_chanctx(... struct ieee80211_chanctx_conf *ctx) ->
hwsim_set_chanctx_magic(ctx)
This also happens in a number of other drivers.
Also, add a code comment to try to prevent people from introducing
new members after `struct ieee80211_chanctx_conf conf`. Notice that
`struct ieee80211_chanctx_conf` is a flexible structure --a structure
that contains a flexible-array member, so it should always be at
the end of any other containing structures.
This change also fixes 50 of the following warnings:
net/mac80211/ieee80211_i.h:895:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are

scx_ops_bypass() can currently race on the ops enable / disable path as
follows:
1. scx_ops_bypass(true) called on enable path, bypass depth is set to 1
2. An op on the init path exits, which schedules scx_ops_disable_workfn()
3. scx_ops_bypass(false) is called on the disable path, and bypass depth
is decremented to 0
4. kthread is scheduled to execute scx_ops_disable_workfn()
5. scx_ops_bypass(true) called, bypass depth set to 1
6. scx_ops_bypass() races when iterating over CPUs
While it's not safe to take any blocking locks on the bypass path, it is
safe to take a raw spinlock which cannot be preempted. This patch therefore
updates scx_ops_bypass() to use a raw spinlock to synchronize, and changes
scx_ops_bypass_depth to be a regular int.
Without this change, we observe the following warnings when running the
'exit' sched_ext selftest (sometimes requires a couple of runs):

If ufshcd_rtc_work calls ufshcd_rpm_put_sync() and the pm's usage_count
is 0, we will enter the runtime suspend callback. However, the runtime
suspend callback will wait to flush ufshcd_rtc_work, causing a deadlock.
Replace ufshcd_rpm_put_sync() with ufshcd_rpm_put() to avoid the
deadlock.

In commit 63fb3ec80516 ("sched_ext: Allow only user DSQs for
scx_bpf_consume(), scx_bpf_dsq_nr_queued() and bpf_iter_scx_dsq_new()"), we
updated the consume path to only accept user DSQs, thus making it invalid
to consume SCX_DSQ_GLOBAL. This selftest was doing that, so let's create a
custom DSQ and use that instead. The test now passes:

It turns out that AMD has a "Meltdown Lite(tm)" issue with non-canonical
accesses in kernel space. And so using just the high bit to decide
whether an access is in user space or kernel space ends up with the good
old "leak speculative data" if you have the right gadget using the
result:
CVE-2020-12965 “Transient Execution of Non-Canonical Accesses“
Now, the kernel surrounds the access with a STAC/CLAC pair, and those
instructions end up serializing execution on older Zen architectures,
which closes the speculation window.
But that was true only up until Zen 5, which renames the AC bit [1].
That improves performance of STAC/CLAC a lot, but also means that the
speculation window is now open.
Note that this affects not just the new address masking, but also the
regular valid_user_address() check used by access_ok(), and the asm
version of the sign bit check in the get_user() helpers.
It does not affect put_user() or clear_user() variants, since there's no
speculative result to be used in a gadget for those operations.

If more than 255 colocated APs exist for the set of all
APs found during 2.4/5 GHz scanning, then the 6 GHz scan
construction will loop forever since the loop variable
has type u8, which can never reach the number found when
that's bigger than 255, and is stored in a u32 variable.
Also move it into the loops to have a smaller scope.
Using a u32 there is fine, we limit the number of APs in
the scan list and each has a limit on the number of RNR
entries due to the frame size. With a limit of 1000 scan
results, a frame size upper bound of 4096 (really it's
more like ~2300) and a TBTT entry size of at least 11,
we get an upper bound for the number of ~372k, well in
the bounds of a u32.

When we free wdev->cqm_config when unregistering, we also
need to clear out the pointer since the same wdev/netdev
may get re-registered in another network namespace, then
destroyed later, running this code again, which results in
a double-free.

Revert commit dfdfe4be183b ("wifi: iwlwifi: remove retry loops in
start"), it turns out that there's an issue with the PNVM load
notification from firmware not getting processed, that this patch
has been somewhat successfully papering over. Since this is being
reported, revert the loop removal for now.
We will later at least clean this up to only attempt to retry if
there was a timeout, but currently we don't even bubble up the
failure reason to the correct layer, only returning NULL.

When we add the vif (and its default link) in fw restart we may
override the link that already exists. We take care of this but if
link 0 is a valid MLO link, then we will re-create a default link on
mvmvif->link[0] and we'll loose the real link we had there.
In non-MLO, we need to re-create the default link upon the interface
creation, this is fine. In MLO, we'll just wait for change_vif_links()
to re-build the links.

1. The size of the response packet is not validated.
2. The response buffer is not freed.
Resolve these issues by switching to iwl_mvm_send_cmd_status(),
which handles both size validation and frees the buffer.
