Volteer devices in the collabora lab are categorized under the

With commit 36bbc5b4ff ("cacheinfo: Allow early detection and population
of cache attributes") the shared cpu list for each cache level higher than
L1 is rebuilt even if the list already has been set up.
This is caused by the removal of the cpumask_empty() check within
cache_shared_cpu_map_setup().
However architectures can enforce that the shared cpu list is not rebuilt
by simply setting cpu_map_populated of the per cpu cache info structure to
true, which is also the fix for this problem.

$ cat /sys/devices/system/cpu/cpu1/cache/index2/shared_cpu_list

This patch reworks and improves the zcrypt retry behavior:
- The zcrypt_rescan_req counter has been removed. This
counter variable has been increased on some transport
errors and was used as a gatekeeper for AP bus rescans.
- Rework of the zcrypt_process_rescan() function to not
use the above counter variable any more. Instead now
always the ap_bus_force_rescan() function is called
(as this has been improved with a previous patch).
- As the zcrpyt_process_rescan() function is called in
all cprb send functions in case of the first attempt
to send failed with ENODEV now before the next attempt
to send an cprb is started.
- Introduce a define ZCRYPT_WAIT_BINDINGS_COMPLETE_MS
for the amount of milliseconds to have the zcrypt API
wait for AP bindings complete. This amount has been
reduced to 30s (was 60s). Some playing around showed
that 30s is a really fair limit.
The result of the above together with the patches to
improve the AP scan bus functions is that after the
first loop of cprb send retries when the result is a
ENODEV the AP bus scan is always triggered (synchronous).
If the AP bus scan detects changes in the configuration,
all the send functions now retry when the first attempt
was failing with ENODEV in the hope that now a suitable
device has appeared.
About concurrency: The ap_bus_force_rescan() uses a mutex
to ensure only one active AP bus scan is running. Another
caller of this function is blocked as long as the scan is
running but does not cause yet another scan. Instead the
result of the 'other' scan is used. This affects only tasks
which run into an initial ENODEV. Tasks with successful
delivery of cprbs will never invoke the bus scan and thus
never get blocked by the mutex.

The both functions zcrypt_send_cprb() and zcrypt_send_ep11_cprb()
are used to send CPRBs in-kernel from different sources. For
example the pkey module may call one of the functions in
zcrypt_ep11misc.c to trigger a derive of a protected key from
a secure key blob via an existing crypto card. These both
functions are then the internal API to send the CPRB and
receive the response.
All the ioctl functions to send an CPRB down to the addressed
crypto card use some kind of retry mechanism. When the first
attempt fails with ENODEV, a bus rescan is triggered and a
loop with retries is carried out.
For the both named internal functions there was never any
retry attempt made. This patch now introduces the retry code
even for this both internal functions to have effectively
same behavior on sending an CPRB from an in-kernel source
and sending an CPRB from userspace via ioctl.

Rework the invocations around ap_scan_bus():
- Protect ap_scan_bus() with a mutex to make sure only one
scan at a time is running.
- The workqueue invocation which is triggered by either the
module init or via AP bus scan timer expiration uses this
mutex and if there is already a scan running, the work
is simple aborted (as the job is done by another task).
- The ap_bus_force_rescan() which is invoked by higher level
layers mostly on failures which indicate a bus scan may
help is reworked to call ap_scan_bus() direct instead of
enqueuing work into a system workqueue and waiting for that
to finish. Of course the mutex is respected and in case of
another task already running a bus scan the shortcut of
waiting for this scan to finish and reusing the scan result
is taken.

The APQN bindings complete completion was used to reflect
that 1st the AP bus initial scan is done and 2nd all the
detected APQNs have been bound to a device driver.
This was a single-shot action. However, as the AP bus
supports hot-plug it may be that new APQNs appear reflected
as new AP queue and card devices which need to be bound
to appropriate device drivers. So the condition that
all existing AP queue devices are bound to device drivers
may go away for a certain time.
This patch now checks during AP bus scan for maybe new AP
devices appearing and does a re-init of the internal completion
variable. So the AP bus function ap_wait_apqn_bindings_complete()
now may block on this condition variable even later after
initial scan is through when new APQNs appear which need to
get bound.
This patch also moves the check for binding complete invocation
from the probe function to the end of the AP bus scan function.
This change also covers some weird scenarios where during a
card hotplug the binding of the card device was sufficient for
binding complete but the queue devices where still in the
process of being discovered.
As of now this change has no impact on existing code. The
behavior change in the now later bindings complete should not
impact any code (and has been tested so far). The only
exploiter is the zcrypt function zcrypt_wait_api_operational()
which only initial calls ap_wait_apqn_bindings_complete().
However, this new behavior of the AP bus wait for APQNs bindings
complete function will be used in a later patch exploiting
this for the zcrypt API layer.

Update vfio_ap_mdev_reset_queue() to handle an unexpected checkstop (hardware error) the

We also stop lying about a queue's reset response code. This was originally done so we

for the hotplug scenario. vfio_ap_mdev_filter_matrix is instead modified to allow
passthrough for all queues with reset state normal, deconfigured, or checkstopped. In the
checkstopped case we choose to pass the device through and let the error state be

get_hugepd_cache_index() should never be called, the only call is behind
an is_hugepd() check, which is always false for this configuration.
Instead mark it as always inline, and change the BUG() to BUILD_BUG().

Patch #1 disallows anonymous sets with timeout, except for dynamic sets.
Anonymous sets with timeouts using the pipapo set backend makes

Patch #2 rejects constant sets with timeout which has no practical usecase.
This kind of set, once bound, contains elements that expire but
no new elements can be added.
Patch #3 restores custom conntrack expectations with NFPROTO_INET,

Patch #4 marks rhashtable anonymous set with timeout as dead from the

The hwdb selection logic as a feature that allows it to mark some fields
as 'don't care'. If we match with such a field we memcpy(..)
the current etnaviv_chip_identity into ident.
This step can overwrite some id values read from the GPU with the
'don't care' value.
Fix this issue by restoring the affected values after the memcpy(..).
As this is crucial for user space to know when this feature works as
expected increment the minor version too.

====================
netrom: Fix all the data-races around sysctls
As the title said, in this patchset I fix the data-race issues because
the writer and the reader can manipulate the same value concurrently.

We need to protect the reader reading the sysctl value because the
value can be changed concurrently.
