The MPTCP port attribute is in host endianness, but was documented
as big-endian in the ynl specification.
Below are two examples from net/mptcp/pm_netlink.c showing that the
attribute is converted to/from host endianness for use with netlink.
Import from netlink:
addr->port = htons(nla_get_u16(tb[MPTCP_PM_ADDR_ATTR_PORT]))
Export to netlink:
nla_put_u16(skb, MPTCP_PM_ADDR_ATTR_PORT, ntohs(addr->port))
Where addr->port is defined as __be16.
No functional change intended.

====================
idpf: XDP chapter II: convert Tx completion to libeth
Alexander Lobakin says:
XDP for idpf is currently 5 chapters:
* convert Rx to libeth;
* convert Tx completion to libeth (this);
* generic XDP and XSk code changes;
* actual XDP for idpf via libeth_xdp;
* XSk for idpf (^).
Part II does the following:
* adds generic libeth Tx completion routines;
* converts idpf to use generic libeth Tx comp routines;
* fixes Tx queue timeouts and robustifies Tx completion in general;
* fixes Tx event/descriptor flushes (writebacks).
Most idpf patches again remove more lines than adds.
Generic Tx completion helpers and structs are needed as libeth_xdp
(Ch. III) makes use of them. WB_ON_ITR is needed since XDPSQs don't
want to work without it at all. Tx queue timeouts fixes are needed
since without them, it's way easier to catch a Tx timeout event when
WB_ON_ITR is enabled.
* '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
idpf: enable WB_ON_ITR
idpf: fix netdev Tx queue stop/wake
idpf: refactor Tx completion routines
netdevice: add netdev_tx_reset_subqueue() shorthand
idpf: convert to libeth Tx buffer completion
libeth: add Tx buffer completion helpers

When processing the netlink GET requests to get PHY info, the req_info.pdn
pointer is NULL when no PHY matches the requested parameters, such as when
the phy_index is invalid, or there's simply no PHY attached to the
interface.
Therefore, check the req_info.pdn pointer for NULL instead of
dereferencing it.

In remove_anno_list_by_saddr(running on CPU2), after leaving the critical

occurrence of uaf in the mptcp_pm_del_add_timer(running on CPU1).
Keeping a reference to add_timer inside the lock, and calling
sk_stop_timer_sync() with this reference, instead of "entry->add_timer".
Move list_del(&entry->list) to mptcp_pm_del_add_timer and inside the pm lock,
do not directly access any members of the entry outside the pm lock, which
can avoid similar "entry->x" uaf.

====================
mptcp: fallback to TCP after 3 MPC drop + cache
The SYN + MPTCP_CAPABLE packets could be explicitly dropped by firewalls
somewhere in the network, e.g. if they decide to drop packets based on
the TCP options, instead of stripping them off.
The idea of this series is to fallback to TCP after 3 SYN+MPC drop
(patch 2). If the connection succeeds after the fallback, it very likely
means a blackhole has been detected. In this case (patch 3), MPTCP can
be disabled for a certain period of time, 1h by default. If after this
period, MPTCP is still blocked, the period is doubled. This technique is
inspired by the one used by TCP FastOpen.
This should help applications which want to use MPTCP by default on the
client side if available.

An MPTCP firewall blackhole can be detected if the following SYN
retransmission after a fallback to "plain" TCP is accepted.
In case of blackhole, a similar technique to the one in place with TFO
is now used: MPTCP can be disabled for a certain period of time, 1h by
default. This time period will grow exponentially when more blackhole
issues get detected right after MPTCP is re-enabled and will reset to
the initial value when the blackhole issue goes away.
The blackhole period can be modified thanks to a new sysctl knob:
blackhole_timeout. Two new MIB counters help understanding what's
happening:
- 'Blackhole', incremented when a blackhole is detected.
- 'MPCapableSYNTXDisabled', incremented when an MPTCP connection
directly falls back to TCP during the blackhole period.
Because the technique is inspired by the one used by TFO, an important
part of the new code is similar to what can find in tcp_fastopen.c, with
some adaptations to the MPTCP case.

Some middleboxes might be nasty with MPTCP, and decide to drop packets
with MPTCP options, instead of just dropping the MPTCP options (or
letting them pass...).
In this case, it sounds better to fallback to "plain" TCP after 2
retransmissions, and try again.

The TAS module could not be configured when it's running in pending
status. We need disable the module and configure it again. However, the
pending status is not cleared after the module disabled. TC taprio set
will always return busy even it's disabled.
For example, a user uses tc-taprio to configure Qbv and a future
basetime. The TAS module will run in a pending status. There is no way
to reconfigure Qbv, it always returns busy.
Actually the TAS module can be reconfigured when it's disabled. So it
doesn't need to check the pending status if the TAS module is disabled.
After the patch, user can delete the tc taprio configuration to disable
Qbv and reconfigure it again.

syzbot reported that the seqnr_lock is not acquire for frames received
over the interlink port. In the interlink case a new seqnr is generated
and assigned to the frame.
Frames, which are received over the slave port have already a sequence
number assigned so the lock is not required.
Acquire the hsr_priv::seqnr_lock during in the invocation of
hsr_forward_skb() if a packet has been received from the interlink port.

A new endpoint using the IP of the initial subflow has been recently
added to increase the code coverage. But it breaks the test when using
old kernels not having commit 86e39e04482b ("mptcp: keep track of local
endpoint still available for each msk"), e.g. on v5.15.
Similar to commit d4c81bbb8600 ("selftests: mptcp: join: support local
endpoint being tracked or not"), it is possible to add the new endpoint
conditionally, by checking if "mptcp_pm_subflow_check_next" is present
in kallsyms: this is not directly linked to the commit introducing this
symbol but for the parent one which is linked anyway. So we can know in
advance what will be the expected behaviour, and add the new endpoint
only when it makes sense to do so.

When running in container environmment, /sys/fs/cgroup/ might not be
the real root node of the sk-attached cgroup.
Example:
In container:
% stat /sys//fs/cgroup/
Device: 0,21 Inode: 2214 ..
% stat /sys/fs/cgroup/foo
Device: 0,21 Inode: 2264 ..
The expectation would be for:
nft add rule .. socket cgroupv2 level 1 "foo" counter
to match traffic from a process that got added to "foo" via
"echo $pid > /sys/fs/cgroup/foo/cgroup.procs".
However, 'level 3' is needed to make this work.
Seen from initial namespace, the complete hierarchy is:
% stat /sys/fs/cgroup/system.slice/docker-.../foo
Device: 0,21 Inode: 2264 ..
i.e. hierarchy is
0 1 2 3
/ -> system.slice -> docker-1... -> foo
... but the container doesn't know that its "/" is the "docker-1.."
cgroup. Current code will retrieve the 'system.slice' cgroup node
and store its kn->id in the destination register, so compare with
2264 ("foo" cgroup id) will not match.
Fetch "/" cgroup from ->init() and add its level to the level we try to
extract. cgroup root-level is 0 for the init-namespace or the level
of the ancestor that is exposed as the cgroup root inside the container.
In the above case, cgrp->level of "/" resolved in the container is 2
(docker-1...scope/) and request for 'level 1' will get adjusted
to fetch the actual level (3).
v2: use CONFIG_SOCK_CGROUP_DATA, eval function depends on it.

In the event that the I2C bus was powered down when the I2C controller
driver loads, or some spurious pulses occur on the I2C bus, it's
possible that the controller detects a spurious I2C "start" condition.
In this situation it may continue to report the bus is busy indefinitely
and block the controller from working.
The "single-master" DT flag can be specified to disable bus busy checks
entirely, but this may not be safe to use in situations where other I2C
masters may potentially exist.
In the event that the controller reports "bus busy" for too long when
starting a transaction, we can try reinitializing the controller to see
if the busy condition clears. This allows recovering from this scenario.

Frequently an I2C write will be followed by a read, such as a register
address write followed by a read of the register value. In this driver,
when the TX FIFO half empty interrupt was raised and it was determined
that there was enough space in the TX FIFO to send the following read
command, it would do so without waiting for the TX FIFO to actually
empty.
Unfortunately it appears that in some cases this can result in a NAK
that was raised by the target device on the write, such as due to an
unsupported register address, being ignored and the subsequent read
being done anyway. This can potentially put the I2C bus into an
invalid state and/or result in invalid read data being processed.
To avoid this, once a message has been fully written to the TX FIFO,
wait for the TX FIFO empty interrupt before moving on to the next
message, to ensure NAKs are handled properly.

Since SPSR_* are not associated with any register in the sysreg array,
nor do they have .get_user()/.set_user() helpers, they are invisible to
userspace with that encoding.
Therefore hidden_user_visibility() serves no purpose here, and can be
safely removed.

We go trough a great deal of effort to map CNTKCTL_EL12 to CNTKCTL_EL1
while hidding this mapping from userspace via a special visibility helper.
However, it would be far simpler to just provide an accessor doing the
mapping job, removing the need for a visibility helper.
With that done, we can also remove the EL12_REG() macro which serves
no purpose.

Avoid unnecessary nested min()/max() which results in egregious macro
expansion.
Use clamp_t() as this introduces the least possible expansion, and turn
the {s,u}DIGIT_FITTING() macros into inline functions to avoid the
nested expansion.
This resolves an issue with slackware 15.0 32-bit compilation as
reported by Richard Narron.
Presumably the min/max fixups would be difficult to backport, this patch
should be easier and fix's Richard's problem in 5.15.

In the pxafb_probe function, it calls the pxafb_init_fbinfo function,
after which &fbi->task is associated with pxafb_task. Moreover,
within this pxafb_init_fbinfo function, the pxafb_blank function
within the &pxafb_ops struct is capable of scheduling work.
If we remove the module which will call pxafb_remove to make cleanup,
it will call unregister_framebuffer function which can call
do_unregister_framebuffer to free fbi->fb through
put_fb_info(fb_info), while the work mentioned above will be used.
The sequence of operations that may lead to a UAF bug is as follows:
