process_rx_list may not copy as many bytes as we want to the userspace
buffer, for example in case we hit an EFAULT during the copy. If this
happens, we should only count the bytes that were actually copied,
which may be 0.
Subtracting async_copy_bytes is correct in both peek and !peek cases,
because decrypted == async_copy_bytes + peeked for the peek case: peek
is always !ZC, and we can go through either the sync or async path. In
the async case, we add chunk to both decrypted and
async_copy_bytes. In the sync case, we add chunk to both decrypted and
peeked. I missed that in commit 6caaf104423d ("tls: fix peeking with
sync+async decryption").

Only MSG_PEEK needs to copy from an offset during the final
process_rx_list call, because the bytes we copied at the beginning of
tls_sw_recvmsg were left on the rx_list. In the KVEC case, we removed
data from the rx_list as we were copying it, so there's no need to use
an offset, just like in the normal case.

Currently, loopback test may be skipped when resetting, but the test
result will still show as 'PASS', because the driver doesn't set

The devlink reload process will access the hardware resources,
but the register operation is done before the hardware is initialized.
So, processing the devlink reload during initialization may lead to kernel

Locally generated IP multicast packets (such as the ones used in the
test) do not perform routing and simply egress the bound device.
However, as explained in commit 8bcfb4ae4d97 ("selftests: forwarding:
Fix failing tests with old libnet"), old versions of libnet (used by
mausezahn) do not use the "SO_BINDTODEVICE" socket option. Specifically,
the library started using the option for IPv6 sockets in version 1.1.6
and for IPv4 sockets in version 1.2. This explains why on Ubuntu - which
uses version 1.1.6 - the IPv4 overlay tests are failing whereas the IPv6
ones are passing.
Fix by specifying the source and destination MAC of the packets which
will cause mausezahn to use a packet socket instead of an IP socket.

Since the Renesas Ethernet Switch driver was added by Yoshihiro Shimoda,
I started receiving the patches to review for it -- which I was unable to
do, as I don't know this hardware and don't even have the manuals for it.
Fortunately, Shimoda-san has volunteered to be a reviewer for this new
driver, thus let's now split the single entry into 3 per-driver entries,
each with its own reviewer...

The MT7530 switch after reset initialises with a core clock frequency that
works with a 25MHz XTAL connected to it. For 40MHz XTAL, the core clock
frequency must be set to 500MHz.
The mt7530_pll_setup() function is responsible of setting the core clock
frequency. Currently, it runs on MT7530 with 25MHz and 40MHz XTAL. This
causes MT7530 switch with 25MHz XTAL to egress and ingress frames
improperly.
Introduce a check to run it only on MT7530 with 40MHz XTAL.
The core clock frequency is set by writing to a switch PHY's register.
Access to the PHY's register is done via the MDIO bus the switch is also
on. Therefore, it works only when the switch makes switch PHYs listen on
the MDIO bus the switch is on. This is controlled either by the state of
the ESW_P1_LED_1 pin after reset deassertion or modifying bit 5 of the
modifiable trap register.
When ESW_P1_LED_1 is pulled high, PHY indirect access is used. That means
accessing PHY registers via the PHY indirect access control register of the
switch.
When ESW_P1_LED_1 is pulled low, PHY direct access is used. That means
accessing PHY registers via the MDIO bus the switch is on.
For MT7530 switch with 40MHz XTAL on a board with ESW_P1_LED_1 pulled high,
the core clock frequency won't be set to 500MHz, causing the switch to
egress and ingress frames improperly.
Run mt7530_pll_setup() after PHY direct access is set on the modifiable
trap register.
With these two changes, all MT7530 switches with 25MHz and 40MHz, and
P1_LED_1 pulled high or low, will egress and ingress frames properly.

We had various syzbot reports about tcp timers firing after
the corresponding netns has been dismantled.
Fortunately Josef Bacik could trigger the issue more often,
and could test a patch I wrote two years ago.
When TCP sockets are closed, we call inet_csk_clear_xmit_timers()
to 'stop' the timers.
inet_csk_clear_xmit_timers() can be called from any context,
including when socket lock is held.
This is the reason it uses sk_stop_timer(), aka del_timer().
This means that ongoing timers might finish much later.
For user sockets, this is fine because each running timer
holds a reference on the socket, and the user socket holds
a reference on the netns.
For kernel sockets, we risk that the netns is freed before
timer can complete, because kernel sockets do not hold
reference on the netns.
This patch adds inet_csk_clear_xmit_timers_sync() function
that using sk_stop_timer_sync() to make sure all timers
are terminated before the kernel socket is released.
Modules using kernel sockets close them in their netns exit()
handler.
Also add sock_not_owned_by_me() helper to get LOCKDEP
support : inet_csk_clear_xmit_timers_sync() must not be called
while socket lock is held.
It is very possible we can revert in the future commit
3a58f13a881e ("net: rds: acquire refcount on TCP sockets")
which attempted to solve the issue in rds only.
(net/smc/af_smc.c and net/mptcp/subflow.c have similar code)
We probably can remove the check_net() tests from
tcp_out_of_resources() and __tcp_close() in the future.

commit e748d0fd66ab ("net: hsr: Disable promiscuous mode in

while creating an HSR interface. But while deleting the
HSR interface, it does not take care of it. It decreases the
promiscuous mode count, which eventually enables promiscuous
mode on the slave devices when creating HSR interface again.
Fix this by not decrementing the promiscuous mode count while
deleting the HSR interface when offload is enabled.

The IO subsystem expects a driver to retry a ccw_device_start, when the
subsequent interrupt response block (irb) contains a deferred
condition code 1.
Symptoms before this commit:
On the read channel we always trigger the next read anyhow, so no
different behaviour here.
On the write channel we may experience timeout errors, because the
expected reply will never be received without the retry.
Other callers of qeth_send_control_data() may wrongly assume that the ccw
was successful, which may cause problems later.
Note that since
commit 2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers")
and
commit 5ef1dc40ffa6 ("s390/cio: fix invalid -EBUSY on ccw_device_start")
deferred CC1s are much more likely to occur. See the commit message of the
latter for more background information.

We encountered a failing case when running selftest in no_alu32 mode:
The failure case is `kfunc_call/kfunc_call_test4` and its source code is
like bellow:
```
long bpf_kfunc_call_test4(signed char a, short b, int c, long d) __ksym;
int kfunc_call_test4(struct __sk_buff *skb)
{
...
tmp = bpf_kfunc_call_test4(-3, -30, -200, -1000);
...
}
```
And its corresponding asm code is:
```
0: r1 = -3
1: r2 = -30
2: r3 = 0xffffff38 # opcode: 18 03 00 00 38 ff ff ff 00 00 00 00 00 00 00 00
4: r4 = -1000
5: call bpf_kfunc_call_test4
```
insn 2 is parsed to ld_imm64 insn to emit 0x00000000ffffff38 imm, and
converted to int type and then send to bpf_kfunc_call_test4. But since
it is zero-extended in the bpf calling convention, riscv jit will
directly treat it as an unsigned 32-bit int value, and then fails with
the message "actual 4294966063 != expected -1234".
The reason is the incompatibility between bpf and riscv abi, that is,
bpf will do zero-extension on uint, but riscv64 requires sign-extension

sk->sk_rcvbuf in __sock_queue_rcv_skb() and __sk_receive_skb() can be

This patch is aimed at reducing the number of benign races reported by

The verifier allows using the addr_space_cast instruction in a program
that doesn't have an associated arena. This was caught in the form an
invalid memory access in do_misc_fixups() when while converting
addr_space_cast to a normal 32-bit mov, env->prog->aux->arena was
dereferenced to check for BPF_F_NO_USER_CONV flag.
Reject programs that include the addr_space_cast instruction but don't
have an associated arena.

The verifier currently converts addr_space_cast from as(1) to as(0) that
is: BPF_ALU64 | BPF_MOV | BPF_X with off=1 and imm=1
to
BPF_ALU | BPF_MOV | BPF_X with imm=1 (32-bit mov)
Because of this imm=1, the JITs that have bpf_jit_needs_zext() == true,
interpret the converted instruction as BPF_ZEXT_REG(DST) which is a
special form of mov32, used for doing explicit zero extension on dst.
These JITs will just zero extend the dst reg and will not move the src to
dst before the zext.
Fix do_misc_fixups() to set imm=0 when converting addr_space_cast to a
normal mov32.
The JITs that have bpf_jit_needs_zext() == true rely on the verifier to
emit zext instructions. Mark dst_reg as subreg when doing cast from
as(1) to as(0) so the verifier emits a zext instruction after the mov.

syzbot reported the following uninit-value access issue [1][2]:
nci_rx_work() parses and processes received packet. When the payload
length is zero, each message type handler reads uninitialized payload
and KMSAN detects this issue. The receipt of a packet with a zero-size
payload is considered unexpected, and therefore, such packets should be
silently discarded.
This patch resolved this issue by checking payload size before calling
each message type handler codes.

Pull remoteproc updates from Bjorn Andersson:
"Qualcomm SM8650 audio, compute and modem remoteproc are added.
Qualcomm X1 Elite audio and compute remoteprocs are added, after
support for shutting down the bootloader-loaded firmware loaded into
the audio DSP..
A dozen drivers in the subsystem are transitioned to use devres
helpers for remoteproc and memory allocations - this makes it possible
to acquire in-kernel handle to individual remoteproc instances in a
cluster.
The release of DMA memory for remoteproc virtio is corrected to ensure
that restarting due to a watchdog bite doesn't attempt to allocate the
memory again without first freeing it.
Last, but not least, a couple of DeviceTree binding cleanups"

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net. There is a
larger batch of fixes still pending that will follow up asap, this is
what I deemed to be more urgent at this time:
1) Use clone view in pipapo set backend to release elements from destroy
path, otherwise it is possible to destroy elements twice.
2) Incorrect check for internal table flags lead to bogus transaction
objects.
3) Fix counters memleak in netdev basechain update error path,
from Quan Tian.

attributes
In the case of firewire core function, the caller of show functions for
device attributes is not only sysfs user, but also device initialization.
This commit adds memo about it against the typical assumption that the
functions are just dedicated to sysfs user.

The tests send 100 pings in 0.1 second intervals and force a timeout of
11 seconds, which is borderline (especially on debug kernels), resulting
in random failures in netdev CI [1].
Fix by increasing the timeout to 20 seconds. It should not prolong the
test unless something is wrong, in which case the test will rightfully
fail.
