HID: bpf: return non NULL data pointer when CONFIG_HID_BPF is not set

dispatch_hid_bpf_device_event() is supposed to return either an error,
or a valid pointer to memory containing the data.

Returning NULL simply makes a segfault when CONFIG_HID_BPF is not set
for any processed event.

HID: bpf jmp table: simplify the logic of cleaning up programs

Kind of a hack, but works for now:

Instead of listening for any close of eBPF program, we now
decrement the refcount when we insert it in our internal
map of fd progs.

This is safe to do because:
- we listen to any call of destructor of programs
- when a program is being destroyed, we disable it by removing
  it from any RCU list used by any HID device (so it will never
  be called)
- we then trigger a job to cleanup the prog fd map, but we overwrite
  the removal of the elements to not do anything on the programs, just
  remove the allocated space

This is better than previously because we can remove the map of known
programs and their usage count. We now rely on the refcount of
bpf, which has greater chances of being accurate.

HID: initial BPF implementation

Declare an entry point that can use fmod_ret BPF programs, and
also an API to access and change the incoming data.

A simpler implementation would consist in just calling
hid_bpf_device_event() for any incoming event and let users deal
with the fact that they will be called for any event of any device.

The goal of HID-BPF is to partially replace drivers, so this situation
can be problematic because we might have programs which will step on
each other toes.

For that, we add a new API hid_bpf_attach_prog() that can be called
from a syscall and we manually deal with a jump table in hid-bpf.

Whenever we add a program to the jump table (in other words, when we
attach a program to a HID device), we keep the number of time we added
this program in the jump table so we can release it whenever there are
no other users.

HID devices have an RCU protected list of available programs in the
jump table, and those programs are called one after the other thanks
to bpf_tail_call().

To achieve the detection of users losing their fds on the programs we
attached, we add 2 tracing facilities on bpf_prog_release() (for when
a fd is closed) and bpf_free_inode() (for when a pinned program gets
unpinned).

As per the documentation, if we jump into the subdirectory by

subdirectory in vmlinux. It is considered as a bug.

ALSA: memalloc: Don't fall back for SG-buffer with IOMMU

When the non-contiguous page allocation for SG buffer allocation
fails, the memalloc helper tries to fall back to the old page
allocation methods.  This would, however, result in the bogus page
addresses when IOMMU is enabled.  Usually in such a case, the fallback
allocation should fail as well, but occasionally it succeeds and
hitting a bad access.

The fallback was thought for non-IOMMU case, and as the error from
dma_alloc_noncontiguous() with IOMMU essentially implies a fatal
memory allocation error, we should return the error straightforwardly
without fallback.  This avoids the corner case like the above.

The patch also renames the local variable "dma_ops" with snd_ prefix
for avoiding the name conflict.

drm/amd/display: Fix reg timeout in enc314_enable_fifo

[Why]
The link enablement sequence can end up resetting the encoder while
the PHY symclk isn't yet on.

This means that waiting for symclk on will timeout, along with the reset
bit never asserting high.

This causes unnecessary delay when enabling the link and produces a
warning affecting multiple IGT tests.

[How]
Don't wait for the symclk to be on here because firmware already does.

Don't wait for reset if we know the symclk isn't on.

Split the reset into a helper function that checks the bit and decides
whether or not a delay is sufficient.

ibmveth: Reduce default tx queues to 8

Previously, the default number of transmit queues was 16. Due to
resource concerns, set to 8 queues instead. Still allow the user
to set more queues (max 16) if they like.

Since the driver is virtualized away from the physical NIC, the purpose
of multiple queues is purely to allow for parallel calls to the
hypervisor. Therefore, there is no noticeable effect on performance by
reducing queue count to 8.

====================
can 2022-11-07

The first patch is by Chen Zhongjin and adds a missing
dev_remove_pack() to the AF_CAN protocol.

Zhengchao Shao's patch fixes a potential NULL pointer deref in
AF_CAN's can_rx_register().

The next patch is by Oliver Hartkopp and targets the CAN ISO-TP
protocol, and fixes the state handling for echo TX processing.

Oliver Hartkopp's patch for the j1939 protocol adds a missing
initialization of the CAN headers inside outgoing skbs.

Another patch by Oliver Hartkopp fixes an out of bounds read in the
check for invalid CAN frames in the xmit callback of virtual CAN
devices. This touches all non virtual device drivers as we decided to
rename the function requiring that netdev_priv points to a struct
can_priv.
(Note: This patch will create a merge conflict with net-next where the
 pch_can driver has removed.)

The last patch is by Geert Uytterhoeven and adds the missing ECC error
checks for the channels 2-7 in the rcar_canfd driver.

In nf_tables_exit_net(), there is a case where nft_net->commit_list is
empty but nft_net->module_list is not empty.  Such a case occurs with
the following scenario:

1. nfnetlink_rcv_batch() is called
2. nf_tables_newset() returns -EAGAIN and NFNL_BATCH_FAILURE bit is
   set to status
3. nf_tables_abort() is called with NFNL_ABORT_AUTOLOAD
   (nft_net->commit_list is released, but nft_net->module_list is not
   because of NFNL_ABORT_AUTOLOAD flag)
4. Jump to replay label
5. netlink_skb_clone() fails and returns from the function (this is
   caused by fault injection in the reproducer of syzbot)

This patch fixes this issue by calling __nf_tables_abort() when
