Make the gpiolib-cdev module a build option. This allows the CDEV
interface to be removed from the kernel to reduce kernel size in
applications where is it not required, and provides the parent for
other CDEV interface specific build options to follow.

Add a new version of the uAPI to address existing 32/64-bit alignment
issues, add support for debounce and event sequence numbers, allow
requested lines with different configurations, and provide some future
proofing by adding padding reserved for future use.
The alignment issue relates to the gpioevent_data, which packs to different
sizes on 32-bit and 64-bit platforms. That creates problems for 32-bit apps
running on 64-bit kernels. uAPI v2 addresses that particular issue, and
the problem more generally, by adding pad fields that explicitly pad
structs out to 64-bit boundaries, so they will pack to the same size now,
and even if some of the reserved padding is used for __u64 fields in the
future.
The new structs have been analysed with pahole to ensure that they
are sized as expected and contain no implicit padding.
The lack of future proofing in v1 makes it impossible to, for example,
add the debounce feature that is included in v2.
The future proofing is addressed by providing configurable attributes in
line config and reserved padding in all structs for future features.
Specifically, the line request, config, info, info_changed and event
structs receive updated versions and new ioctls.
As the majority of the structs and ioctls were being replaced, it is
opportune to rework some of the other aspects of the uAPI:
v1 has three different flags fields, each with their own separate
bit definitions. In v2 that is collapsed to one - gpio_v2_line_flag.
The handle and event requests are merged into a single request, the line
request, as the two requests were mostly the same other than the edge
detection provided by event requests. As a byproduct, the v2 uAPI allows
for multiple lines producing edge events on the same line handle.
This is a new capability as v1 only supports a single line in an event
request.
As a consequence, there are now only two types of file handle to be
concerned with, the chip and the line, and it is clearer which ioctls
apply to which type of handle.
There is also some minor renaming of fields for consistency compared to
their v1 counterparts, e.g. offset rather than lineoffset or line_offset,
and consumer rather than consumer_label.
Additionally, v1 GPIOHANDLES_MAX becomes GPIO_V2_LINES_MAX in v2 for
clarity, and the gpiohandle_data __u8 array becomes a bitmap in
gpio_v2_line_values.
The v2 uAPI is mostly a reorganisation and extension of v1, so userspace
code, particularly libgpiod, should readily port to it.

Replace usage of strncpy() with strscpy() to remove -Wstringop-truncation
warnings.
The structures being populated are zeroed, to prevent stack leakage as
they are returned to userspace, so strscpy() performs the equivalent
function without the warnings.

Set the value of the line info offset in gpio_desc_to_lineinfo(), rather

GPIO line names are currently created by the driver from the chip label.
We'll want to support custom formats for line names (for instance: to

While we do check the "chip-name" property in probe(), we never actually

The property is renamed to "chip-label" to not cause any confusion with
the actual chip name which is of the form: "gpiochipX".
If the "chip-label" property is missing, let's do what most devices in

which acquires a mutex and when used from iscsi_tcp devices can now lead to

Ensure that the spinlock is released before calling getpeername() or

mptcp: Fix for 32-bit DATA_FIN
The main fix is contained in patch 2, and that commit message explains
the issue with not properly converting truncated DATA_FIN sequence
numbers sent by the peer.
With patch 2 adding an unlocked read of msk->ack_seq, patch 1 cleans up
access to that data with READ_ONCE/WRITE_ONCE.
This does introduce two merge conflicts with net-next, but both have
straightforward resolution. Patch 1 modifies a line that got removed in
net-next so the modification can be dropped when merging. Patch 2 will
require a trivial conflict resolution for a modified function

The peer may send a DATA_FIN mapping with either a 32-bit or 64-bit

autofs got broken in some configurations by commit 13c164b1a186
("autofs: switch to kernel_write") because there is now an extra LSM
permission check done by security_file_permission() in rw_verify_area().
autofs is one if the few places that really does want the much more
limited __kernel_write(), because the write is an internal kernel one
that shouldn't do any user permission checks (it also doesn't need the
file_start_write/file_end_write logic, since it's just a pipe).
There are a couple of other cases like that - accounting, core dumping,
and splice - but autofs stands out because it can be built as a module.
As a result, we need to export this internal __kernel_write() function
again.
We really don't want any other module to use this, but we don't have a
"EXPORT_SYMBOL_FOR_AUTOFS_ONLY()". But we can mark it GPL-only to at
least approximate that "internal use only" for licensing.
While in this area, make autofs pass in NULL for the file position
pointer, since it's always a pipe, and we now use a NULL file pointer
for streaming file descriptors (see file_ppos() and commit 438ab720c675:
"vfs: pass ppos=NULL to .read()/.write() of FMODE_STREAM files")
This effectively reverts commits 9db977522449 ("fs: unexport
__kernel_write") and 13c164b1a186 ("autofs: switch to kernel_write").

In rhine_resume() and rhine_suspend(), the code calls netif_running()
to see if the network interface is down or not. If it is down (i.e.,
netif_running() returning false), they will skip any housekeeping work
within the function relating to the hardware. This becomes a problem
when the hardware resumes from a standby since it is counting on
rhine_resume() to map its MMIO and power up rest of the hardware.
Not getting its MMIO remapped and rest of the hardware powered
up lead to a soft reset failure and hardware disappearance. The
solution is to map its MMIO and power up rest of the hardware inside
rhine_open() before soft reset is to be performed. This solution was
verified on ASUS P5V800-VM mainboard's integrated Rhine-II Ethernet
MAC inside VIA Technologies VT8251 South Bridge.

Consequences of this bug is that the power reference would

We marked /sys/fs/selinux/checkreqprot as deprecated in Linux v5.7,
but didn't provide any guidance as to the timeframe. Considering
the state of checkreqprot, it seems like one year should be enough
time.

When building with
$ HOST_EXTRACFLAGS=-g make
the expectation is that host tools are built with debug informations.
This however doesn't happen if the Makefile assigns a new value to the
HOST_EXTRACFLAGS instead of appending to it. So use += instead of := for
the first assignment.
