====================
Expose port split attributes
Danielle says:
Currently, user space has no way of knowing if a port can be split and
into how many ports. Among other things, this makes it impossible to
write generic tests for port split functionality.
Therefore, this set exposes two new devlink port attributes to user
space: Number of lanes and whether the port can be split or not.
Patch set overview:
Patches #1-#4 cleanup 'struct devlink_port_attrs' and reduce the number
of parameters passed between drivers and devlink via
devlink_port_attrs_set()
Patch #5 adds devlink port lanes attributes
Patches #6-#7 add devlink port splittable attribute
Patch #8 exploits the fact that devlink is now aware of port's number of
lanes and whether the port can be split or not and moves some checks
from drivers to devlink
Patch #9 adds a port split test
Changes since v2:
* Remove some local variables from patch #3
* Reword function description in patch #5
* Fix a bug in patch #8
* Add a test for the splittable attribute in patch #9
Changes since v1:
* Rename 'width' attribute to 'lanes'
* Add 'splittable' attribute
* Move checks from drivers to devlink

Test port split configuration using previously added number of port lanes
attribute.
Check that all the splittable ports are successfully split to their maximum
number of lanes and below, and that those which are not splittable fail to
be split.
Test output example:
TEST: swp4 is unsplittable [ OK ]
TEST: split port swp53 into 4 [ OK ]
TEST: Unsplit port pci/0000:03:00.0/25 [ OK ]
TEST: split port swp53 into 2 [ OK ]

bpf_sk_reuseport_detach is currently called when sk->sk_user_data
is not NULL. It is incorrect because sk->sk_user_data may not be
managed by the bpf's reuseport_array. It has been reported in [1] that,
the bpf_sk_reuseport_detach() which is called from udp_lib_unhash() has
corrupted the sk_user_data managed by l2tp.
This patch solves it by using another bit (defined as SK_USER_DATA_BPF)
of the sk_user_data pointer value. It marks that a sk_user_data is
managed/owned by BPF.
The patch depends on a PTRMASK introduced in
commit f1ff5ce2cd ("net, sk_msg: Clear sk_user_data pointer on clone if tagged").
[ Note: sk->sk_user_data is used by bpf's reuseport_array only when a sk is
added to the bpf's reuseport_array.
i.e. doing setsockopt(SO_REUSEPORT) and having "sk->sk_reuseport == 1"
alone will not stop sk->sk_user_data being used by other means. ]

It makes little sense for copying sk_user_data of reuseport_array during
sk_clone_lock(). This patch reuses the SK_USER_DATA_NOCOPY bit introduced in
commit f1ff5ce2cd ("net, sk_msg: Clear sk_user_data pointer on clone if tagged").
It is used to mark the sk_user_data is not supposed to be copied to its clone.
Although the cloned sk's sk_user_data will not be used/freed in
bpf_sk_reuseport_detach(), this change can still allow the cloned
sk's sk_user_data to be used by some other means.
Freeing the reuseport_array's sk_user_data does not require a rcu grace
period. Thus, the existing rcu_assign_sk_user_data_nocopy() is not
used.

Add events with a type of 0x0010 and a code of 0x57 / 0x58,
this silences the following messages being logged on a
Dell Inspiron 5593:
dell_wmi: Unknown key with type 0x0010 and code 0x0057 pressed
dell_wmi: Unknown key with type 0x0010 and code 0x0058 pressed
These are brightness events and will be handled by acpi-video

Many Bay Trail and Cherry Trail devices come with a camera attached to
Intel's Image Signal Processor. Linux currently does not have a driver for
these, so they do not work as a camera.
Some of these camera's have a status LED which is controlled through a GPIO
in some cases, e.g. on the Asus T100TA and Asus T200TA, there is a firmware
issue where the LED gets turned on at boot.
This commit adds a Linux LED driver for the camera LED on these devices.
This driver will turn the LED off at boot and also allows controlling the
LED (so the user can repurpose it) through the sysfs LED interface.
Which GPIO is attached to the LED is usually not described in the ACPI
tables, so this driver contains per-system info about the GPIO inside the
driver. This means that this driver only works on systems the driver knows
about.

Since the aliasing-ppgtt remains the default for gen6/gen7, it is worth
optimising the ppgtt allocation for it. In this case, we do not need to
flush the GGTT page directories entries as they are fixed during setup.

system76_set() was set as an LED ->brightness_set() callback, but it calls
acpi_evaluate_object() which is not atomic-safe. Switch to the

====================
mptcp: introduce msk diag interface
This series implements the diag interface for the MPTCP sockets.
Since the MPTCP protocol value can't be represented with the
current diag uAPI, the first patch introduces an extended attribute
allowing user-space to specify lager protocol values.
The token APIs are then extended to allow traversing the
whole token container.
Patch 3 carries the actual diag interface implementation, and
later patch bring-in some functional self-tests.

mptcp_token_iter_next() allow traversing all the MPTCP
sockets inside the token container belonging to the given
network namespace with a quite standard iterator semantic.
That will be used by the next patch, but keep the API generic,
as we plan to use this later for PM's sake.
Additionally export mptcp_token_get_sock(), as it also
will be used by the diag module.

After commit bf9765145b ("sock: Make sk_protocol a 16-bit value")
the current size of 'sdiag_protocol' is not sufficient to represent
the possible protocol values.
This change introduces a new inet diag request attribute to let
user space specify the relevant protocol number using u32 values.
The attribute is parsed by inet diag core on get/dump command
and the extended protocol value, if available, is preferred to
'sdiag_protocol' to lookup the diag handler.
The parse attributed are exposed to all the diag handlers via
the cb->data.
Note that inet_diag_dump_one_icsk() is left unmodified, as it
will not be used by protocol using the extended attribute.

If the genlmsg_put() call in ethnl_default_dumpit() fails, we bail out
without checking if we already have some messages in current skb like we do
with ethnl_default_dump_one() failure later. Therefore if existing messages
almost fill up the buffer so that there is not enough space even for
netlink and genetlink header, we lose all prepared messages and return and
error.
Rather than duplicating the skb->len check, move the genlmsg_put(),
genlmsg_cancel() and genlmsg_end() calls into ethnl_default_dump_one().
This is also more logical as all message composition will be in
ethnl_default_dump_one() and only iteration logic will be left in
ethnl_default_dumpit().
