This reverts commit 82ea174dc5.
Unfortunately according to our recent findings there is still some
unidentified factor, requiring CDCLK to be set higher - otherwise we
still get underruns on some multipipe configurations, despite CDCLK
being set according to BSpec formula. So getting again back into debug
mode to indentify the cause, meanwhile setting CDCLK=Pixel rate back in
order to remove regression in 10% of the cases due to FIFO underruns.

In some cases, when an error occurs during testing and the main test
routine returns, a memory leak occurs via leaving previously registered
shadow variables allocated in the kernel as well as shadow_ptr list
elements. From now on, in case of error, remove all allocated shadow
variables and shadow_ptr struct elements.

This change makes the test feel more familiar with narrowing to a
typical usage by operating on a number of identical structure instances
and populating the same two new shadow variables symmetrically while
keeping the same testing and verification criteria for the extra
variables.

The initial idea was to make a change to please cppcheck and remove void
pointer arithmetics found a few times:
portability: 'obj' is of type 'void *'. When using void pointers
in calculations, the behaviour is undefined.
[arithOperationsOnVoidPointer]
The rest of the changes are to help make the test read as an example
while continuing to verify the shadow variable code. The logic of the
test is unchanged but restructured to use descriptive names.

The test-klp-callbacks script includes a few tests which rely on kernel
task timings that may not always execute as expected under system load.
These may generate out of sequence kernel log messages that result in
test failure.
Instead of using sleep timing windows to orchestrate these tests, add a
block_transition module parameter to communicate the test purpose and
utilize flush_queue() to serialize the test module's task output.

It is preferable to allow suspend even when Bluetooth has problems
preparing for sleep. When Bluetooth fails to finish preparing for
suspend, log the error and allow the suspend notifier to continue
instead.
To also make it clearer why suspend failed, change bt_dev_dbg to
bt_dev_err when handling the suspend timeout.

qca_suspend() removes the vote for the UART TX clock after
writing an IBS sleep request to the serial buffer. This is
not a good idea since there is no guarantee that the request
has been sent at this point. Instead remove the vote after
successfully entering IBS sleep. This also fixes the issue
of the vote being removed in case of an aborted suspend due
to a failure of entering IBS sleep.

While trying to use the lantiq_gswip driver on one of my boards I made
a mistake when specifying the phy-mode (because the out-of-tree driver
wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the
following error is printed multiple times:
Unsupported interface: 3
While it gives at least a hint at what may be wrong it is not very user
friendly. Print the human readable phy-mode and also which port is
configured incorrectly (this hardware supports ports 0..6) to improve
the cases where someone made a mistake.

The driver registers three different types of thermal zones: For the
ASIC itself, for port modules and for gearboxes.
Currently, all three types use the same get_trend() callback which does
not work correctly for the ASIC thermal zone. The callback assumes that
the device data is of type 'struct mlxsw_thermal_module', whereas for
the ASIC thermal zone 'struct mlxsw_thermal' is passed as device data.
Fix this by using one get_trend() callback for the ASIC thermal zone and
another for the other two types.

Commit 6cc7c266e5 ("ima: Call ima_calc_boot_aggregate() in
ima_eventdigest_init()") added a call to ima_calc_boot_aggregate() so that
the digest can be recalculated for the boot_aggregate measurement entry if
the 'd' template field has been requested. For the 'd' field, only SHA1 and
MD5 digests are accepted.
Given that ima_eventdigest_init() does not have the __init annotation, all
functions called should not have it. This patch removes __init from
ima_pcrread().

IPC MU has no power domain assigned and there could be IPC during
noirq suspend phase, so IRQF_NO_SUSPEND flag is needed for IPC MU.
However, for other MUs, they have power domain assigned and their
power will be turned off during noirq suspend phase, but with
IRQF_NO_SUSPEND set, their interrupts are NOT disabled even after
their power turned off, it will cause system crash when mailbox
driver trys to handle pending interrupts but the MU power is already
turned off.
So, IRQF_NO_SUSPEND flag should ONLY be added to IPC MU which has
power domain managed by SCU, then all other MUs' pending interrupts
after noirq suspend phase will be handled after system resume.

Some of i.MX8M SoCs have MU clock, they need to be managed in runtime
to make sure the MU clock can be off in runtime, add runtime PM callback
to handle MU clock.
And on i.MX8MP, the MU clock is combined with power domain and runtime
PM is enabled for the clock driver, during noirq suspend/resume phase,
runtime PM is disabled by device suspend, but the MU context save/restore
needs to enable MU clock for register access, calling clock prepare/enable
will trigger runtime resume failure and lead to system suspend failed.
Actually, the MU context save/restore is ONLY necessary for SCU IPC MU,
other MUs especially on i.MX8MP platforms which have MU clock assigned,
they need to runtime request/free mailbox channel in the consumer driver,
so no need to save/restore MU context for them, hence it can avoid this
issue, so the MU context save/restore is ONLY applied to i.MX platforms
MU instance without clock present.

For "mem" mode suspend on i.MX8 SoCs, MU settings could be
lost because its power is off, so save/restore is needed
for MU settings during suspend/resume. However, the restore
can ONLY be done when MU settings are actually lost, for the
scenario of settings NOT lost in "freeze" mode suspend, since
there could be still IPC going on multiple CPUs, restoring the
MU settings could overwrite the TIE by mistake and cause system
freeze, so need to make sure ONLY restore the MU settings when
it is powered off, Anson fixes this by checking whether restore
is actually needed when resume.

Fix two issues with introspecting the task mode.
1. If a task is attached to a unconfined profile that is not the
ns->unconfined profile then. Mode the mode is always reported
as -
$ ps -Z
LABEL PID TTY TIME CMD
unconfined 1287 pts/0 00:00:01 bash
test (-) 1892 pts/0 00:00:00 ps
instead of the correct value of (unconfined) as shown below
$ ps -Z
LABEL PID TTY TIME CMD
unconfined 2483 pts/0 00:00:01 bash
test (unconfined) 3591 pts/0 00:00:00 ps
2. if a task is confined by a stack of profiles that are unconfined
the output of label mode is again the incorrect value of (-) like
above, instead of (unconfined). This is because the visibile
profile count increment is skipped by the special casing of
unconfined.

Currently apparmor_sk_clone_security() does not check for existing
label/peer in the 'new' struct sock; it just overwrites it, if any
(with another reference to the label of the source sock.)
static void apparmor_sk_clone_security(const struct sock *sk,
struct sock *newsk)
{
struct aa_sk_ctx *ctx = SK_CTX(sk);
struct aa_sk_ctx *new = SK_CTX(newsk);
new->label = aa_get_label(ctx->label);
new->peer = aa_get_label(ctx->peer);
}
This might leak label references, which might overflow under load.
Thus, check for and put labels, to prevent such errors.
Note this is similarly done on:
static int apparmor_socket_post_create(struct socket *sock, ...)
...
if (sock->sk) {
struct aa_sk_ctx *ctx = SK_CTX(sock->sk);
aa_put_label(ctx->label);
ctx->label = aa_get_label(label);
}
...
Context:
-------
The label reference count leak is observed if apparmor_sock_graft()
is called previously: this sets the 'ctx->label' field by getting
a reference to the current label (later overwritten, without put.)
static void apparmor_sock_graft(struct sock *sk, ...)
{
struct aa_sk_ctx *ctx = SK_CTX(sk);
if (!ctx->label)
ctx->label = aa_get_current_label();
}
And that is the case on crypto/af_alg.c:af_alg_accept():
int af_alg_accept(struct sock *sk, struct socket *newsock, ...)
...
struct sock *sk2;
...
sk2 = sk_alloc(...);
...
security_sock_graft(sk2, newsock);
security_sk_clone(sk, sk2);
...
Apparently both calls are done on their own right, especially for
other LSMs, being introduced in 2010/2014, before apparmor socket
mediation in 2017 (see commits [1,2,3,4]).
So, it looks OK there! Let's fix the reference leak in apparmor.
Test-case:
---------
Exercise that code path enough to overflow label reference count.
$ cat aa-refcnt-af_alg.c
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <sys/socket.h>

}

Gen12+. It adds definitions of IO buffer Wake and Fast Wake for pre Gen12
and Gen12+. And it aligns PSR2 definition macros.
v2: Fix macro definitions. (José)
v3: Addressed review comments from José
- Add missing default values of IO_BUFFER_WAKE and FAST_WAKE for GEN9+
- Change a style of macro naming in order to use lines as input.
- Update Todo comments.
v4: Add parentheses to macros to avoid precedence issues.

"Here is the large set of staging and IIO driver changes for 5.8-rc1
Nothing major, but a lot of new IIO drivers are included in here,
along with other core iio cleanups and changes.
On the staging driver front, again, nothing noticable. No new
deletions or additions, just a ton of tiny cleanups all over the tree
done by a lot of different people. Most coding style, but many actual
real fixes and cleanups that are nice to see.
All of these have been in linux-next for a while with no reported
issues"

Here is the tty and serial driver updates for 5.8-rc1
Nothing huge at all, just a lot of little serial driver fixes, updates
for new devices and features, and other small things. Full details are
in the shortlog.
Note, you will get a conflict merging with your tree in the
Documentation/devicetree/bindings/serial/rs485.yaml file, but it should
be pretty obvious what to do. If not, I'm sure Rob will clean it all up
afterwards :)
All of these have been in linux-next with no issues for a while.

blk_mq_all_tag_iter() is added to iterate all requests, so we should
fetch the request from ->static_rqs][] instead of ->rqs[] which is for
holding in-flight request only.
