fc683f967a sound fixes for 5.12-rc4
A slightly high volume at this time due to pending ASoC fixes.
 While there are a few generic simple-card fixes for regressions,
 most of the changes are device-specific fixes: ASoC Intel SOF, codec
 clocks, other codec / platform fixes as well as usual HD-audio and
 USB-audio.

ae605ee983 xprtrdma: Revert 586a0787ce
Commit 9ed5af268e ("SUNRPC: Clean up the handling of page padding
in rpc_prepare_reply_pages()") [Dec 2020] affects RPC Replies that
have a data payload (i.e., Write chunks).

rpcrdma_prepare_readch(), as its name suggests, sets up Read chunks
which are data payloads within RPC Calls. Those payloads are
constructed by xdr_write_pages(), which continues to stuff the call
buffer's tail kvec with the payload's XDR roundup. Thus removing
the tail buffer logic in rpcrdma_prepare_readch() was the wrong
thing to do.

Since commit bdcc2cd14e ("NFSv4.2: handle NFS-specific llseek errors"),
nfs42_proc_llseek would return -EOPNOTSUPP rather than -ENOTSUPP when
SEEK_DATA on NFSv4.0/v4.1.

This will lead xfstests generic/285 not run on NFSv4.0/v4.1 when set the
CONFIG_NFS_V4_2, rather than run failed.

d58300c318 mptcp: validate 'id' when stopping the ADD_ADDR retransmit timer
when Linux receives an echo-ed ADD_ADDR, it checks the IP address against
the list of "announced" addresses. In case of a positive match, the timer
that handles retransmissions is stopped regardless of the 'Address Id' in
the received packet: this behaviour does not comply with RFC8684 3.4.1.

Fix it by validating the 'Address Id' in received echo-ed ADD_ADDRs.
Tested using packetdrill, with the following captured output:

20b5759f21 mptcp: avoid OOB access in setsockopt()
We can't use tcp_set_congestion_control() on an mptcp socket, as
such function can end-up accessing a tcp-specific field -
prior_ssthresh - causing an OOB access.

To allow propagating the correct ca algo on subflow, cache the ca
name at initialization time.

Additionally avoid overriding the user-selected CA (if any) at
clone time.

17f9c1b63c net: mvpp2: add buffer header handling in RX
If Link Partner sends frames larger than RX buffer size, MAC mark it
as oversize but still would pass it to the Packet Processor.
In this scenario, Packet Processor scatter frame between multiple buffers,
but only a single buffer would be returned to the Buffer Manager pool and
it would not refill the poll.

Patch add handling of oversize error with buffer header handling, so all
buffers would be returned to the Buffer Manager pool.

9453d45ecb net: zero-initialize tc skb extension on allocation
Function skb_ext_add() doesn't initialize created skb extension with any
value and leaves it up to the user. However, since extension of type
TC_SKB_EXT originally contained only single value tc_skb_ext->chain its
users used to just assign the chain value without setting whole extension
memory to zero first. This assumption changed when TC_SKB_EXT extension was
extended with additional fields but not all users were updated to
initialize the new fields which leads to use of uninitialized memory
afterwards. UBSAN log:

Fix another "confused deputy" weakness[1]. Writes to /proc/$pid/attr/

trick another process (which may have different credentials) to write
to its own /proc/$pid/attr/ files, leading to unexpected and possibly
exploitable behaviors.

0c1f3193b1 dm verity: fix require_signatures module_param permissions
The third parameter of module_param() is permissions for the sysfs node
but it looks like it is being used as the initial value of the parameter
here.  In fact, false here equates to omitting the file from sysfs and
does not affect the value of require_signatures.

Making the parameter writable is not simple because going from
false->true is fine but it should not be possible to remove the
requirement to verify a signature.  But it can be useful to inspect the
value of this parameter from userspace, so change the permissions to
make a read-only file in sysfs.

a703619127 bpf: No need to simulate speculative domain for immediates
In 801c6058d1 ("bpf: Fix leakage of uninitialized bpf stack under
speculation") we replaced masking logic with direct loads of immediates
if the register is a known constant. Given in this case we do not apply
any masking, there is also no reason for the operation to be truncated
under the speculative domain.

Therefore, there is also zero reason for the verifier to branch-off and
simulate this case, it only needs to do it for unknown but bounded scalars.
As a side-effect, this also enables few test cases that were previously
rejected due to simulation under zero truncation.

Masking direction as indicated via mask_to_left is considered to be

needs to be placed into bpf_sanitize_info instead so we can pass it

corner case where the off reg causes masking direction change which
then results in an incorrect final aux->alu_limit.

Similarly as 6bdacdb48e ("bpf: Fix BPF_JIT kconfig symbol dependency") we

implicit by its dependency on BPF_JIT which itself was dependent on NET (but
without any actual/real hard dependency code-wise). Given the latter was
lifted, so should be the former as BPF_LSMs could well exist on net-less
systems. This therefore also fixes a randconfig build error recently reported

6fd5fb6382 selftests/bpf: Add test for l3 use of bpf_redirect_peer
Add a test case for using bpf_skb_change_head() in combination with
bpf_redirect_peer() to redirect a packet from a L3 device to veth and back.

The test uses a BPF program that adds L2 headers to the packet coming
from a L3 device and then calls bpf_redirect_peer() to redirect the packet
to a veth device. The test fails as skb->mac_len is not set properly and
thus the ethernet headers are not properly skb_pull'd in cls_bpf_classify(),
causing tcp_v4_rcv() to point the TCP header into middle of the IP header.
