Sean Young says:
====================
The kernel IR decoders (drivers/media/rc/ir-*-decoder.c) support the most
widely used IR protocols, but there are many protocols which are not
supported[1]. For example, the lirc-remotes[2] repo has over 2700 remotes,
many of which are not supported by rc-core. There is a "long tail" of
unsupported IR protocols, for which lircd is need to decode the IR .
IR encoding is done in such a way that some simple circuit can decode it;
therefore, bpf is ideal.
In order to support all these protocols, here we have bpf based IR decoding.
The idea is that user-space can define a decoder in bpf, attach it to
the rc device through the lirc chardev.
Separate work is underway to extend ir-keytable to have an extensive library
of bpf-based decoders, and a much expanded library of rc keymaps.
Another future application would be to compile IRP[3] to a IR BPF program, and
so support virtually every remote without having to write a decoder for each.
It might also be possible to support non-button devices such as analog
directional pads or air conditioning remote controls and decode the target
temperature in bpf, and pass that to an input device.

Changes since v4:
- Renamed rc_dev_bpf_{attach,detach,query} to lirc_bpf_{attach,detach,query}
- Fixed error path in lirc_bpf_query
- Rebased on bpf-next
Changes since v3:
- Implemented review comments from Quentin Monnet and Y Song (thanks!)
- More helpful and better formatted bpf helper documentation
- Changed back to bpf_prog_array rather than open-coded implementation
- scancodes can be 64 bit
- bpf gets passed values in microseconds, not nanoseconds.
microseconds is more than than enough (IR receivers support carriers upto
70kHz, at which point a single period is already 14 microseconds). Also,
this makes it much more consistent with lirc mode2.
- Since it looks much more like lirc mode2, rename the program type to
BPF_PROG_TYPE_LIRC_MODE2.
- Rebased on bpf-next
Changes since v2:
- Fixed locking issues
- Improved self-test to cover more cases
- Rebased on bpf-next again
Changes since v1:
- Code review comments from Y Song <ys114321@gmail.com> and

- Rebase on bpf-next

The OPP binding says:
Property: operating-points-v2
...
This can contain more than one phandle for power domain
providers that provide multiple power domains. That is, one
phandle for each power domain. If only one phandle is available,
then the same OPP table will be used for all power domains
provided by the power domain provider.
But the OPP core isn't allowing the same OPP table to be used for
multiple domains. Update dev_pm_opp_of_add_table_indexed() to allow

Tests showed, that the zcrypt device driver produces memory
leaks when a valid CCA or EP11 CPRB can't get delivered or has
a failure during processing within the zcrypt device driver.
This happens when a invalid domain or adapter number is used
or the lower level software or hardware layers produce any
kind of failure during processing of the request.
Only CPRBs send to CCA or EP11 cards can produce this memory
leak. The accelerator and the CPRBs processed by this type
of crypto card is not affected.
The two fields message and private within the ap_message struct
are allocated with pulling the function code for the CPRB but
only freed when processing of the CPRB succeeds. So for example
an invalid domain or adapter field causes the processing to
fail, leaving these two memory areas allocated forever.

The arch_get_random_seed_long() invocation done by the random device
driver is done in interrupt context and may be invoked very very
frequently. The existing s390 arch_get_random_seed*() implementation
uses the PRNO(TRNG) instruction which produces excellent high quality
entropy but is relatively slow and thus expensive.
This fix reworks the arch_get_random_seed* implementation. It
introduces a buffer concept to decouple the delivery of random data
via arch_get_random_seed*() from the generation of new random
bytes. The buffer of random data is filled asynchronously by a
workqueue thread.
If there are enough bytes in the buffer the s390_arch_random_generate()
just delivers these bytes. Otherwise false is returned until the worker
thread refills the buffer.
The worker fills the rng buffer by pulling fresh entropy from the
high quality (but slow) true hardware random generator. This entropy
is then spread over the buffer with an pseudo random generator.
As the arch_get_random_seed_long() fetches 8 bytes and the calling
function add_interrupt_randomness() counts this as 1 bit entropy the
distribution needs to make sure there is in fact 1 bit entropy
contained in 8 bytes of the buffer. The current values pull 32 byte
entropy and scatter this into a 2048 byte buffer. So 8 byte in the
buffer will contain 1 bit of entropy.
The worker thread is rescheduled based on the charge level of the
buffer but at least with 500 ms delay to avoid too much cpu consumption.
So the max. amount of rng data delivered via arch_get_random_seed is
limited to 4Kb per second.

This avoids the init_cpufreq_transition_notifier_list() initcall. Its

If the policy limits are updated via cpufreq_update_policy() and
subsequently via sysfs, the limits stored in user_policy may be
set incorrectly.
For example, if both min and max are set via sysfs to the maximum
available frequency, user_policy.min and user_policy.max will also
be the maximum. If a policy notifier triggered by
cpufreq_update_policy() lowers both the min and the max at this
point, that change is not reflected by the user_policy limits, so
if the max is updated again via sysfs to the same lower value,
then user_policy.max will be lower than user_policy.min which
shouldn't happen. In particular, if one of the policy CPUs is
then taken offline and back online, cpufreq_set_policy() will
fail for it due to a failing limits check.
To prevent that from happening, initialize the min and max fields
of the new_policy object to the ones stored in user_policy that
were previously set via sysfs.

Initially in this code, the race didn't matter since it didn't
do anything. Latest with the commit I marked this as fixing it
started to matter as something got done here that needed other
data that got freed as soon as the queue notification wait was
returning.
In the scenario we saw, apparently the IWL_MVM_RXQ_NOTIF_DEL_BA
event was sent to all queues, but processing the last event we
returned from iwl_mvm_sync_rx_queues_internal() and then from
iwl_mvm_free_reorder() and continued some processing before
wl_mvm_del_ba() was even invoked on the other CPU. Thus, when
the latter finally ran, it found that mvm->baid_map[baid] was
no longer valid.
Correct the race by moving the counter decrement and wake_up()
to be done only after all the per-event processing completed.
Note that in the commit I marked as being fixed the wake_up()
didn't exist yet (and the code was otherwise problematic) but
this particular problem already existed in a way.

Our hardware has a limited amount of buffer descriptors
for each Tx packet. Because of that, there is a short
piece of code that makes sure that that we don't push too
many subframes in an A-MSDU because of subframes needs 2
buffer descriptors. This code also takes into account the
number of fragment of the skb since we also need a buffer
descriptor for each fragment in the skb.
This piece of code though didn't check that the resulting
number of subframes wasn't 0.
A user reported that using NFS client, he could get skbs
that are so fragmented that the code mentioned above
returned 0 for the number of subframes making
skb_gso_segment fail and subconsequently iwlwifi would WARN.
Fix this by make sure that num_subframes is at least 1.

In some cases we may get from FW errored frames with
UNKNOWN security type.
This may happen in unsecured aggregation flow, where
the first packet had a CRC error in the WEP bit, which
was followed by a failure to decrypt and was dropped.
The next frames in the aggregation "inherit" the bad metadata
of the first packet.
Make sure to drop such frames since RADA and other offloads
will not operate correctly which may have unexpected results.
In case of AP it also causes to TX AMSDU frames to the peers,
