am65-cpsw uses page_pool_dev_alloc_pages(), thus needs PAGE_POOL
selected to avoid linker errors. This is missing since the driver
started to use page_pool helpers in 8acacc40f733 ("net: ethernet:
ti: am65-cpsw: Add minimal XDP support")

Although the PCI device ID and Vendor ID for the RPM (MAC) block
have remained the same across Octeon CN10K and the next-generation
CN20K silicon, Hardware architecture has changed (NIX mapped RPMs
and RFOE Mapped RPMs).
Add PCI Subsystem IDs to the device table to ensure that this driver
can be probed from NIX mapped RPM devices only.

without balance()
a6250aa251ea ("sched_ext: Handle cases where pick_task_scx() is called
without preceding balance_scx()") added a workaround to handle the cases
where pick_task_scx() is called without prececing balance_scx() which is due
to a fair class bug where pick_taks_fair() may return NULL after a true
return from balance_fair().
The workaround detects when pick_task_scx() is called without preceding
balance_scx() and emulates SCX_RQ_BAL_KEEP and triggers kicking to avoid
stalling. Unfortunately, the workaround code was testing whether @prev was
on SCX to decide whether to keep the task running. This is incorrect as the
task may be on SCX but no longer runnable.
This could lead to a non-runnable task to be returned from pick_task_scx()
which cause interesting confusions and failures. e.g. A common failure mode
is the task ending up with (!on_rq && on_cpu) state which can cause
potential wakers to busy loop, which can easily lead to deadlocks.
Fix it by testing whether @prev has SCX_TASK_QUEUED set. This makes
@prev_on_scx only used in one place. Open code the usage and improve the
comment while at it.

ASUS VivoBook 15 with SSID 1043:1460 took an incorrect quirk via the
pin pattern matching for ASUS (ALC256_FIXUP_ASUS_MIC), resulting in
the two built-in mic pins (0x13 and 0x1b). This had worked without
problems casually in the past because the right pin (0x1b) was picked
up as the primary device. But since we fixed the pin enumeration for
other bugs, the bogus one (0x13) is picked up as the primary device,
hence the bug surfaced now.
For addressing the regression, this patch explicitly specifies the
quirk entry with ALC256_FIXUP_ASUS_MIC_NO_PRESENCE, which sets up only
the headset mic pin.

When SPI is used for control, the driver must hold the SPI bus lock
while issuing the sequence of writes to perform a soft reset.
>From the time the driver writes the SYSTEM_RESET command until the
driver does a write to terminate the reset, there must not be any
activity on the SPI bus lines. If there is any SPI activity during the
soft-reset, another soft-reset will be triggered. The state of the SPI
chip select is irrelevant.
A repeated soft-reset does not in itself cause any problems, and it is
not an infinite loop. The problem is a race between these resets and
the driver polling for boot completion. There is a time window between
soft resets where the driver could read HALO_STATE as 2 (fully booted)
while the chip is actually soft-resetting. Although this window is
small, it is long enough that it is possible to hit it in normal
operation.
To prevent this race and ensure the chip really is fully booted, the
driver calls spi_bus_lock() to prevent other activity while resetting.
It then issues the SYSTEM_RESET mailbox command. After allowing
sufficient time for reset to take effect, the driver issues a PING
mailbox command, which will force completion of the full soft-reset
sequence. The SPI bus lock can then be released. The mailbox is
checked for any boot or wakeup response from the firmware, before the
value in HALO_STATE will be trusted.
This does not affect SoundWire or I2C control.

Change calls to async regmap write functions to use the normal
blocking writes so that the cs35l56 driver can use spi_bus_lock() to
gain exclusive access to the SPI bus.
As this is part of a fix, it makes only the minimal change to swap the
functions to the blocking equivalents. There's no need to risk
reworking the buffer allocation logic that is now partially redundant.
The async writes are a 12-year-old workaround for inefficiency of
synchronous writes in the SPI subsystem. The SPI subsystem has since
been changed to avoid the overheads, so this workaround should not be
necessary.
The cs35l56 driver needs to use spi_bus_lock() prevent bus activity
while it is soft-resetting the cs35l56. But spi_bus_lock() is
incompatible with spi_async() calls, which will fail with -EBUSY.

We found an issue when using bpf_redirect with ipvs NAT mode after
commit ff70202b2d1a ("dev_forward_skb: do not scrub skb mark within
the same name space"). Particularly, we use bpf_redirect to return
the skb directly back to the netif it comes from, i.e., xnet is
false in skb_scrub_packet(), and then ipvs_property is preserved
and SNAT is skipped in the rx path.
ipvs_property has been already cleared when netns is changed in
commit 2b5ec1a5f973 ("netfilter/ipvs: clear ipvs_property flag when
SKB net namespace changed"). This patch just clears it in spite of
netns.

A small cleanup, reordering the conditions to avoid checking things
twice.
The code here is called in case of timeout on a TCP connection, before
triggering a retransmission. But it only acts on SYN + MPC packets.
So the conditions can be re-order to exit early in case of non-MPTCP
SYN + MPC. This also reduce the indentation levels.

Thanks for the previous commit ("mptcp: sched: split get_subflow
interface into two"), the mptcp_sched_data structure is now currently
unused.
This structure has been added to allow future extensions that are not
ready yet. At the end, this structure will not even be used at all when
mptcp_subflow bpf_iter will be supported [1].
Here is a first step to save 64 bytes on the stack for each scheduling
operation. The structure is not removed yet not to break the WIP work on
these extensions, but will be done when [1] will be ready and applied.

get_retrans() interface of the burst packet scheduler invokes a sleeping
function mptcp_pm_subflow_chk_stale(), which calls __lock_sock_fast().
So get_retrans() interface should be set with BPF_F_SLEEPABLE flag in
BPF. But get_send() interface of this scheduler can't be set with
BPF_F_SLEEPABLE flag since it's invoked in ack_update_msk() under mptcp
data lock.
So this patch has to split get_subflow() interface of packet scheduer into
two interfaces: get_send() and get_retrans(). Then we can set get_retrans()
interface alone with BPF_F_SLEEPABLE flag.

If an endpoint doesn't have the 'subflow' flag -- in fact, has no type,
so not 'subflow', 'signal', nor 'implicit' -- there are then no subflows
created from this local endpoint to at least the initial destination
address. In this case, no need to call mptcp_pm_nl_fullmesh() which is
there to recreate the subflows to reflect the new value of the fullmesh
attribute.
Similarly, there is then no need to iterate over all connections to do
nothing, if only the 'fullmesh' flag has been changed, and the endpoint
doesn't have the 'subflow' one. So stop early when dealing with this
specific case.

Tariq Toukan says:
====================
net/mlx5e: Move IPSec policy check after decryption
This series by Jianbo adds IPsec policy check after decryption.
In current mlx5 driver, the policy check is done before decryption for
IPSec crypto and packet offload. This series changes that order to
make it consistent with the processing in kernel xfrm. Besides, RX
state with UPSPEC selector is supported correctly after new steering
table is added after decryption and before the policy check.

Previously, the upper layer matches are added for the decryption rule
when xfrm selector's UPSPEC is specified in the command. However, it's
impossible as packets are not decrypted, and there is no way to do
match on the upper protocol (TCP/UDP) with specific source/destination
port. The result is that packets are not decrypted by hardware because
of this mismatch. Instead, they are forwarded to kernel, and
decryption is done by software.
To resolve this issue, this patch adds new table (sa_sel) after status
table and before policy table. When UPSPEC's proto is specified in
xfrm state's selector, a rule is added in status table to forward the
decrypted packets to sa_sel table, where the corresponding rule for
selector's UPSPEC is added, and packet's upper headers are checked
there. If matched, they will be forward to policy table to do policy
check. Otherwise, they are dropped immediately.
Besides, add a global count for this kind of packet drop.

This flow group is added for the pass rules for both crypto offload

For crypto offload, there is no xfrm policy rule offloaded to
hardware, so no need to continue with policy check for it.
Previously, for crypto offload, the hardware metadata reg c4 is not
used and not changed, but set to ASO_OK(0) before decryption to avoid
garbage data. Then a default rule is added to check ipsec_syndrome and
this register. Packets are forwarded to policy table if succeed, or
drop if fails.
According to hardware document, this register value could be 0, 1.
So a special value (0xAA), which is not used by hardware, is chosen as
an indication for crypto offload. It is set to c4 before decryption.
Then a default rule, which matches on 0xAA (and ipsec_syndrome on 0),
is added, which means packets are done by crypto offload, and
sends them to kernel directly, thus skips the policy check.

Currently, xfrm policy check is done before decryption in mlx5 driver.
If matching any policy, packets are forwarded to xfrm state table for
decryption. But this is exact opposite to what software does. For
kernel implementation, xfrm decode is unconditionally activated
whenever an IPSec packet reaches the input flow if there’s a matching
state rule.
This patch changes the order, move policy check after decryption.
Besides, a miss flow table is added at the end for legacy mode, to
make it easier to update the default destination of the steering rules.
So ESP packets are firstly forwarded to SA table for decryption, then
the result is checked in status table. If the decryption succeeds,
packets are forwarded to another table to check xfrm policy rules.
When a policy with allow action is matched, if in legacy mode packets
are forwarded to miss flow table with one rule to forward them to RoCE
tables, if in switchdev mode they are forwarded directly to TC root
chain instead.

In commit dddb49b63d86 ("net/mlx5e: Add IPsec and ASO syndromes check
in HW"), IPSec and ASO syndromes checks after decryption for the
specified ASO object were added. But they are correct only for eswith
in legacy mode. For switchdev mode, metadata register c1 is used to
save the mapped id (not ASO object id). So, need to change the match
accordingly for the check rules in status table.

For eswitch in legacy mode, the packets decrypted in RX SA table will
continue to be processed for RoCE. But this is not necessary for the
un-decrypted packets, which don't match any decryption rules but hit
the miss rule at the end of the table. So, change the destination of
miss rule to TTC default one and skip RoCE.
For eswitch in switchdev mode, the destination is unchanged.

Pull RISC-V fixes from Palmer Dabbelt:
- A fix for cacheinfo DT probing to avoid reading non-boolean
properties as booleans.
- A fix for cpufeature to use bitmap_equal() instead of memcmp(), so
unused bits are ignored.
- Fixes for cmpxchg and futex cmpxchg that properly encode the sign
extension requirements on inline asm, which results in spurious
successes. This manifests in at least inode_set_ctime_current, but is
likely just a disaster waiting to happen.
- A fix for the rseq selftests, which was using an invalid constraint.
- A pair of fixes for signal frame size handling:
- We were reserving space for an extra empty extension context
header on systems with extended signal context, thus resulting in
unnecessarily large allocations.
- We weren't properly checking for available extensions before
calculating the signal stack size, which resulted in undersized
stack allocations on some systems (at least those with T-Head
custom vectors).
Also, we've added Alex as a reviewer. He's been helping out a ton
lately, thanks!
