pwm: Changes for v6.8-rc1
This contains a bunch of cleanups and simplifications across the board, as well as a number of small fixes. Perhaps the most notable change here is the addition of an API that allows PWMs to be used in atomic contexts, which is useful when time- critical operations are involved, such as using a PWM to generate IR signals. Finally, I have decided to step down as PWM subsystem maintainer. Due to other responsibilities I have lately not been able to find the time that the subsystem deserves and Uwe, who has been helping out a lot for the past few years and has many things planned for the future, has kindly volunteered to take over. I have no doubt that he will be a suitable replacement. -----BEGIN PGP SIGNATURE----- iQJNBAABCAA3FiEEiOrDCAFJzPfAjcif3SOs138+s6EFAmWhYQAZHHRoaWVycnku cmVkaW5nQGdtYWlsLmNvbQAKCRDdI6zXfz6zobK8EACtzJX+AeoTkN2S671A7QoG IGl9mrFhvrqN/6syigAIU8ZGOgb5uScZDH58PeTXH/oGEMn+bhQ9MK7JyWF5BUzF I8p6CqaVjG66LsfWz1m8AEAl/0N2Sc2032fWQSJB0o8qgYH0ZRBKc1j371Zm2DgD HT78pZJDSnyCnltPKjbDLShRfBwGINspmbihZKFa6yxrPbvADixCTo19b9Pk8XGa S9k2R/9S/QKPxvB+3DiZAHFstwoTn2p+1IBsg+hp/jLniw8XidZp2Rq0RJuwTjqO jVQDnOFOqNBa3VQccvNe23rDaKUkrmYwk+zzuFF27URam2Gp9wHZ8Y86WPSO5TA9 ftNsoeW++R25PBsOVZFGMU9r9aI9XI1tNyVuv2blNc0yr1fNSRzwjcELzLzG2myp gHgdayJofnvlKM7JV5ZDY6BDPwTP9jfDRdZOqKKNUeB8e9IiQD9JtAV9P+EL/5Hl C+7mh5Xb17bVlczWHqNkTd89Omp+Eu2z5BMfJyiQWQ2lzZpxOkBwB0nrlPshZpPi hz5IhsGjREkEfNV2qz/YDEyaj+CAYO8toitFGt5HeAYTftuG4WD49rHE5VQ8nhwg P9XpWNFHK2EtpU3/BRuupWHZRVd7MU4kMx4WQvWZGOFEqc9DYaC29ynk6sK0ryaC ba8U4gpBS66d3wNvVpkN3A== =pIh8 -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm updates from Thierry Reding: "This contains a bunch of cleanups and simplifications across the board, as well as a number of small fixes.

sound updates for 6.8-rc1
It was a clam development cycle. There were an ALSA core extension
for subformat PCM bits and a few ASoC core changes to support N:M
mappings, while the most of remaining changes are driver-specific.
Core:
- API extensions for properly limiting PCM format bits via subformat
- Enhanced support for N:M CPU:CODEC mappings in the core and in
audio-graph-card2
ASoC:
- Lots of SOF updates: fallback support to older IPC versions,
notification on control changes with IPC4.
Also supports for ACPI parse for the ES83xx driver that reduces
quirks.
- Device tree support for describing parts of the card which can be
active over suspend (for very low power playback or wake word use
cases)
- Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
SM8250, SM8550, SM8650 and X1E80100
- Drop of Freescale MPC8610 code that is no longer supported
HD-audio:
- More CS35L41 codec extensions for Dell, HP and Lenovo models
- TAS2781 codec extensions for Lenovo and co
- New PCM subformat supports
Others:
- More enhancement for Scarlett2 USB mixer support
- Various kselftest fixes

Pull sound updates from Takashi Iwai:
"It was a calm development cycle. There were an ALSA core extension for
subformat PCM bits and a few ASoC core changes to support N:M
mappings, while the most of remaining changes are driver-specific.
Core:
- API extensions for properly limiting PCM format bits via subformat
- Enhanced support for N:M CPU:CODEC mappings in the core and in
audio-graph-card2
ASoC:
- Lots of SOF updates: fallback support to older IPC versions,
notification on control changes with IPC4. Also supports for ACPI
parse for the ES83xx driver that reduces quirks.
- Device tree support for describing parts of the card which can be
active over suspend (for very low power playback or wake word use
cases)
- Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
SM8250, SM8550, SM8650 and X1E80100
- Drop of Freescale MPC8610 code that is no longer supported
HD-audio:
- More CS35L41 codec extensions for Dell, HP and Lenovo models
- TAS2781 codec extensions for Lenovo and co
- New PCM subformat supports
Others:
- More enhancement for Scarlett2 USB mixer support
- Various kselftest fixes"

Pull drm updates from Dave Airlie:
"This contains two major new drivers:
- imagination is a first driver for Imagination Technologies devices,
it only covers very specific devices, but there is hope to grow it
- xe is a reboot of the i915 GPU (shares display) side using a more
upstream focused development model, and trying to maximise code
sharing. It's not enabled for any hw by default, and will hopefully
get switched on for Intel's Lunarlake.
This also drops a bunch of the old UMS ioctls. It's been dead long
enough.
amdgpu has a bunch of new color management code that is being used in
the Steam Deck.
amdgpu also has a new ACPI WBRF interaction to help avoid radio
interference.

MAINTAINERS: pwm: Thierry steps down, Uwe takes over
It's not easy to let go responsibility for a subsystem that one cared
for for a long time, but Thierry realized that his heart isn't in the
pwm framework any more.
Thierry cared for the pwm subsystem (commit 200efedd8766 ("pwm: Take
over maintainership of the PWM subsystem")) as a maintainer during
nearly 12 years. A big thanks for the time, effort and dedication spend
during that time.
Uwe takes over maintenance.

fbdev/intelfb: Remove driver
From looking at the PCI IDs, every device supported by intelfb is also supported by i915. Anyone still using intelfb should please move on to i915, which does everything intelfb does but better. Removing intelfb is motivated by the driver's excessive use of the global screen_info state. The state belongs to architecture and firmware code; device drivers should not attempt to access it. But fixing intelfb would require a significant change in the driver's probing logic. As intelfb has been obsolete for nearly 2 decades, it is probably not worth the effort. Let's just remove it. Also remove the related documentation. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maik Broemme <mbroemme@libmpq.org> Signed-off-by: Helge Deller <deller@gmx.de> |

fbdev: amba-clcd: Delete the old CLCD driver
We have managed to ascertain that all users of the old FBDEV
code that are out of tree are now gone.
The new DRM driver can be found in drivers/gpu/drm/pl111/.
The remaining out of tree user was the ARM FVP emulation
platform, running Android. Thanks to changes in Android
versions 13 and 14, Android can now use the DRM driver when
being emulated under FVP. Some final patches are being put
in place to make it fully featured.
This is essentially a revert of the partial revert in
commit 112c35237c72 ("Partially revert "video: fbdev: amba-clcd: Retire elder CLCD driver"")

Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
warning that was added in 6.2.
- Some reworking of the Documentation/process front page to, hopefully,
make it more useful.
- Various kernel-doc tweaks to, for example, make it deal properly with
__counted_by annotations.
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained
effort by Randy, Vegard, and myself has addressed almost all of those,
bringing the documentation back into sync with the code. The fixes are
going through the appropriate maintainer trees.
- Various improvements to the HTML rendered docs, including automatic links
to Git revisions and a nice new pulldown to make translations easy to
access.
- Speaking of translations, more of those for Spanish and Chinese.
...plus the usual stream of documentation updates and typo fixes.

MAINTAINERS: Bluetooth: retire Johan (for now?)
Johan moved to maintaining the Zephyr Bluetooth stack,
and we haven't heard from him on the ML in 3 years
(according to lore), and seen any tags in git in 4 years.
Trade the MAINTAINER entry for CREDITS, we can revert
whenever Johan comes back to Linux hacking :)

ARM: SoC code changes for 6.8
There are two notable changes this time:
- Andrew Davis adds a arch/arm/Kconfig.platforms file to simplify
the platforms that have no code except their Kconfig file
- Linux Walleij removes support for the ARM11MPCore CPU in
the versatile/realview platform. Since this is the last
remaining one after removing ox820, some core code can go
as well.
The other changes are minor cleanups and bugfixes.

SoC: driver updates for 6.8
A new drivers/cache/ subsystem is added to contain drivers for abstracting
cache flush methods on riscv and potentially others, as this is needed for
handling non-coherent DMA but several SoCs require nonstandard hardware
methods for it.
op-tee gains support for asynchronous notification with FF-A, as well
as support for a system thread for executing in secure world.
The tee, reset, bus, memory and scmi subsystems have a couple of minor
updates.
Platform specific soc driver changes include:
- Samsung Exynos gains driver support for Google GS101 (Tensor G1)
across multiple subsystems
- Qualcomm Snapdragon gains support for SM8650 and X1E along with
added features for some other SoCs
- Mediatek adds support for "Smart Voltage Scaling" on MT8186 and MT8195,
and driver support for MT8188 along with some code refactoring.
- Microchip Polarfire FPGA support for "Auto Update" of the FPGA bitstream
- Apple M1 mailbox driver is rewritten into a SoC driver
- minor updates on amlogic, mvebu, ti, zynq, imx, renesas and hisilicon

Pull SoC driver updates from Arnd Bergmann:
"A new drivers/cache/ subsystem is added to contain drivers for
abstracting cache flush methods on riscv and potentially others, as
this is needed for handling non-coherent DMA but several SoCs require
nonstandard hardware methods for it.
op-tee gains support for asynchronous notification with FF-A, as well
as support for a system thread for executing in secure world.
The tee, reset, bus, memory and scmi subsystems have a couple of minor
updates.
Platform specific soc driver changes include:
- Samsung Exynos gains driver support for Google GS101 (Tensor G1)
across multiple subsystems
- Qualcomm Snapdragon gains support for SM8650 and X1E along with
added features for some other SoCs
- Mediatek adds support for "Smart Voltage Scaling" on MT8186 and
MT8195, and driver support for MT8188 along with some code
refactoring.
- Microchip Polarfire FPGA support for "Auto Update" of the FPGA
bitstream
- Apple M1 mailbox driver is rewritten into a SoC driver
- minor updates on amlogic, mvebu, ti, zynq, imx, renesas and
hisilicon"

SoC: DT changes for 6.8
There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
already supported chips.
The other six new SoCs are all part of existing arm64 families, but
are somewhat more interesting:
- Samsung ExynosAutov920 is an automotive chip, and the first one
we support based on the Cortex-A78AE core with lockstep mode.
- Google gs101 (Tensor G1) is the chip used in a number of Pixel phones,
and is grouped with Samsung Exynos here since it is based on the same
SoC design, sharing most of its IP blocks with that series.
- MediaTek MT8188 is a new chip used for mid-range tablets and Chromebooks,
using two Cortex-A78 cores where the older MT8195 had four of them.
- Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
phone SoC and the first supported chip based on Cortex-X4, Cortex-A720
and Cortex-A520.
- Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest
Laptop chip using the custom Oryon cores.
- Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
Cortex-A76 and Cortex-A55
In terms of boards, we have
- Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.
- Multiple Rockchips mobile gaming systems (Anbernic RG351V,
Powkiddy RK2023, Powkiddy X55) along with the Sonoff iHost Smart
Home Hub and a few Rockchips SBCs
- Some ComXpress boards based on Marvell CN913x, which is the
follow-up to Armada 7xxx/8xxx.
- Six new industrial/embedded boards based on NXP i.MX8 and i.MX9
- Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.
- Toradex Verdin AM62 Mallow carrier for TI AM62
- Huashan Pi board based on the SophGo CV1812H RISC-V chip
- Two boards based on Allwinner H616/H618
- A number of reference boards for various added SoCs from Qualcomm,
Mediatek, Google, Samsung, NXP and Spreadtrum
As usual, there are cleanups and warning fixes across all platforms as
well as added features for several of them.

Networking changes for 6.8.
Core & protocols
----------------
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up
build time warnings to safeguard against future header changes.
This improves TCP performances with many concurrent connections
up to 40%.
- Add page-pool netlink-based introspection, exposing the
memory usage and recycling stats. This helps indentify
bad PP users and possible leaks.
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set.
This lowers the time taken by connect() for hosts having
many active connections to the same destination.
- Refactor the TCP bind conflict code, shrinking related socket
structs.
- Refactor TCP SYN-Cookie handling, as a preparation step to
allow arbitrary SYN-Cookie processing via eBPF.
- Tune optmem_max for 0-copy usage, increasing the default value
to 128KB and namespecifying it.
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations.
- Reduce extension header parsing overhead at GRO time.
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries.
- Reorder nftables struct members, to keep data accessed by the
datapath first.
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer.
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex).
- More data-race annotations.
- Extend the diag interface to dump TCP bound-only sockets.
- Conditional notification of events for TC qdisc class and actions.
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID.
- Implement SMCv2.1 virtual ISM device support.
- Add support for Batman-avd mulicast packet type.
BPF
---
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers. It
improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload.
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y.
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques.
- Support uid/gid options when mounting bpffs.
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is identified
by its id.
- Extend verifier to allow bpf_refcount_acquire() of a map value field
obtained via direct load which is a use-case needed in sched_ext.
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter.
- Support for VLAN tag in XDP hints.
- Remove deprecated bpfilter kernel leftovers given the project
is developed in user-space (https://github.com/facebook/bpfilter).
Misc
----
- Support for parellel TC self-tests execution.
- Increase MPTCP self-tests coverage.
- Updated the bridge documentation, including several so-far
undocumented features.
- Convert all the net self-tests to run in unique netns, to
avoid random failures due to conflict and allow concurrent
runs.
- Add TCP-AO self-tests.
- Add kunit tests for both cfg80211 and mac80211.
- Autogenerate Netlink families documentation from YAML spec.
- Add yml-gen support for fixed headers and recursive nests, the
tool can now generate user-space code for all genetlink families
for which we have specs.
- A bunch of additional module descriptions fixes.
- Catch incorrect freeing of pages belonging to a page pool.
Driver API
----------
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust.
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship.
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances.
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host.
- Add support for ethtool symmetric-xor RSS hash.
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform.
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute.
- Convert older drivers to platform remove callback returning void.
- Add support for PHY package MMD read/write.

sysctl-6.8-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size
penalty sysctl has been changed to allow us to not require the sentinel, the
final empty element on the sysctl array. Joel Granados has been doing all this
work. On the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7 we had all arch/ and drivers/ modified to remove
the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only.
The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches
are still being reviewed. After that we then can expect also the removal of the
no longer needed check for procname == NULL.
Let us recap the purpose of this work:
- this helps reduce the overall build time size of the kernel and run time
memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move sysctls
out from kernel/sysctl.c to their own files
Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further
work by Thomas Weißschuh with the constificatin of the struct ctl_table.
Due to Joel Granados's work, and to help bring in new blood, I have suggested
for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward
to seeing him sent you a pull request for further sysctl changes. This also
removes Iurii Zaikin as a maintainer as he has moved on to other projects and
has had no time to help at all.

bcachefs updates for 6.8:
- btree write buffer rewrite: instead of adding keys to the btree write
buffer at transaction commit time, we know journal them with a
different journal entry type and copy them from the journal to the
write buffer just prior to journal write.
This reduces the number of atomic operations on shared cachelines
in the transaction commit path and is a signicant performance
improvement on some workloads: multithreaded 4k random writes went
from ~650k iops to ~850k iops.
- Bring back optimistic spinning for six locks: the new implementation
doesn't use osq locks; instead we add to the lock waitlist as normal,
and then spin on the lock_acquired bit in the waitlist entry, _not_
the lock itself.
- BCH_IOCTL_DEV_USAGE_V2, which allows for new data types
- BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of fsck
but without mounting: useful for transparently using the kernel
version of fsck from 'bcachefs fsck' when the kernel version is a
better match for the on disk filesystem.
- BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported yet,
but the passes that are supported are fully featured - errors may be
corrected as normal.
The new ioctls use the new 'thread_with_file' abstraction for kicking
off a kthread that's tied to a file descriptor returned to userspace
via the ioctl.
- btree_paths within a btree_trans are now dynamically growable,
instead of being limited to 64. This is important for the
check_directory_structure phase of fsck, and also fixes some issues
we were having with btree path overflow in the reflink btree.
- Trigger refactoring; prep work for the upcoming disk space accounting
rewrite
- Numerous bugfixes :)

New code for 6.8:
* New features/functionality
* Online repair
* Reserve disk space for online repairs.
* Fix misinteraction between the AIL and btree bulkloader because of

happens to be on the AIL list.
* Prevent transaction reservation overflows when reaping blocks during
online repair.
* Whenever possible, bulkloader now copies multiple records into a
block.
* Support repairing of
1. Per-AG free space, inode and refcount btrees.
2. Ondisk inodes.
3. File data and attribute fork mappings.
* Verify the contents of
1. Inode and data fork of realtime bitmap file.
2. Quota files.
* Introduce MF_MEM_PRE_REMOVE. This will be used to notify tasks about
a pmem device being removed.
* Bug fixes
* Fix memory leak of recovered attri intent items.
* Fix UAF during log intent recovery.
* Fix realtime geometry integer overflows.
* Prevent scrub from live locking in xchk_iget.
* Prevent fs shutdown when removing files during low free disk space.
* Prevent transaction reservation overflow when extending an RT device.

filesystem.
* Fix an off-by-one error in xreap_agextent_binval.
* Serialize access to perag radix tree during deletion operation.
* Fix perag memory leak during growfs.
* Allow allocation of minlen realtime extent when the maximum sized
realtime free extent is minlen in size.
* Cleanups
* Remove duplicate boilerplate code spread across functionality associated
with different log items.
* Cleanup resblks interfaces.
* Pass defer ops pointer to defer helpers instead of an enum.
* Initialize di_crc in xfs_log_dinode to prevent KMSAN warnings.
* Use static_assert() instead of BUILD_BUG_ON_MSG() to validate size of
structures and structure member offsets. This is done in order to be
able to share the code with userspace.
* Move XFS documentation under a new directory specific to XFS.
* Do not invoke deferred ops' ->create_done callback if the deferred
operation does not have an intent item associated with it.
* Remove duplicate inclusion of header files from scrub/health.c.

Input: driver for Adafruit Seesaw Gamepad
Adds a driver for a mini gamepad that communicates over i2c, the gamepad
has bidirectional thumb stick input and six buttons.
The gamepad chip utilizes the open framework from Adafruit called 'Seesaw'
to transmit the ADC data for the joystick and digital pin state for the
buttons. I have only implemented the functionality required to receive the
thumb stick and button state.
Steps in reading the gamepad state over i2c:
1. Reset the registers
2. Set the pin mode of the pins specified by the `BUTTON_MASK` to input
`BUTTON_MASK`: A bit-map for the six digital pins internally
connected to the joystick buttons.
3. Enable internal pullup resistors for the `BUTTON_MASK`
4. Bulk set the pin state HIGH for `BUTTON_MASK`
5. Poll the device for button and joystick state done by:
`seesaw_read_data(struct i2c_client *client, struct seesaw_data *data)`

* MTD
Apart from preventing the mtdblk to run on top of ftl or ubiblk (which
may cause security issues and has no meaning anyway), there are a few
misc fixes.
* Raw NAND
Two meaningful changes this time. The conversion of the brcmnand driver
to the ->exec_op() API, this series brought additional changes to the
core in order to help controller drivers to handle themselves the WP pin
during destructive operations when relevant.
There is also a series bringing important fixes to the sequential read
feature.
As always, there is as well a whole bunch of miscellaneous W=1 fixes,
together with a few runtime fixes (double free, timeout value, OOB
layout, missing register initialization) and the usual load of remove
callbacks turned into void (which led to switch the txx9ndfmc driver to
use module_platform_driver()).
* SPI NOR
SPI NOR comes with die erase support for multi die flashes, with new
octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an updated
documentation about what the contributors shall consider when proposing
flash additions or updates.
Michael Walle stepped out from the reviewer role to maintainer.

spi: Updates for v6.8
A moderately busy release for SPI, the main core update was the merging
of support for multiple chip selects, used in some flash configurations.
There were also big overhauls for the AXI SPI Engine and PL022 drivers,
plus some new device support for ST.
There's a few patches for other trees, API updates to allow the
multiple chip select support and one of the naming modernisations
touched a controller embedded in the USB code.
- Support for multiple chip selects.
- A big overhaul for the AXI SPI engine driver, modernising it and
adding a bunch of new features.
- Modernisation of the PL022 driver, fixing some issues with submitting
messages while in atomic context in the process.
- Many drivers were converted to use new APIs which avoid outdated
terminology for devices and controllers.
- Support for ST Microelectronics STM32F7 and STM32MP25, and Renesas
RZ/Five.

The first syscall simply lists the LSMs enabled, while the second and third get and set the current process' LSM attributes. Yes, these syscalls may provide similar functionality to what can be found under /proc or /sys, but they were designed to support multiple, simultaneaous (stacked) LSMs from the start as opposed to the current /proc based solutions which were created at a time when only one LSM was allowed to be active at a given time. We have spent considerable time discussing ways to extend the existing /proc interfaces to support multiple, simultaneaous LSMs and even our best ideas have been far too ugly to support as a kernel API; after +20 years in the kernel, I felt the LSM layer had established itself enough to justify a handful of syscalls. Support amongst the individual LSM developers has been nearly unanimous, with a single objection coming from Tetsuo (TOMOYO) as he is worried that the LSM_ID_XXX token concept will make it more difficult for out-of-tree LSMs to survive. Several members of the LSM community have demonstrated the ability for out-of-tree LSMs to continue to exist by picking high/unused LSM_ID values as well as pointing out that many kernel APIs rely on integer identifiers, e.g. syscalls (!), but unfortunately Tetsuo's objections remain. My personal opinion is that while I have no interest in penalizing out-of-tree LSMs, I'm not going to penalize in-tree development to support out-of-tree development, and I view this as a necessary step forward to support the push for expanded LSM stacking and reduce our reliance on /proc and /sys which has occassionally been problematic for some container users. Finally, we have included the linux-api folks on (all?) recent revisions of the patchset and addressed all of their concerns. - Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit ioctls on 64-bit systems problem. This patch includes support for all of the existing LSMs which provide ioctl hooks, although it turns out only SELinux actually cares about the individual ioctls. It is worth noting that while Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this patch, they did both indicate they are okay with the changes. - Fix a potential memory leak in the CALIPSO code when IPv6 is disabled at boot. While it's good that we are fixing this, I doubt this is something users are seeing in the wild as you need to both disable IPv6 and then attempt to configure IPv6 labeled networking via NetLabel/CALIPSO; that just doesn't make much sense. Normally this would go through netdev, but Jakub asked me to take this patch and of all the trees I maintain, the LSM tree seemed like the best fit. - Update the LSM MAINTAINERS entry with additional information about our process docs, patchwork, bug reporting, etc. I also noticed that the Lockdown LSM is missing a dedicated MAINTAINERS entry so I've added that to the pull request. I've been working with one of the major Lockdown authors/contributors to see if they are willing to step up and assume a Lockdown maintainer role; hopefully that will happen soon, but in the meantime I'll continue to look after it. - Add a handful of mailmap entries for Serge Hallyn and myself. * tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (27 commits) lsm: new security_file_ioctl_compat() hook lsm: Add a __counted_by() annotation to lsm_ctx.ctx calipso: fix memory leak in netlbl_calipso_add_pass() selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test MAINTAINERS: add an entry for the lockdown LSM MAINTAINERS: update the LSM entry mailmap: add entries for Serge Hallyn's dead accounts mailmap: update/replace my old email addresses lsm: mark the lsm_id variables are marked as static lsm: convert security_setselfattr() to use memdup_user() lsm: align based on pointer length in lsm_fill_user_ctx() lsm: consolidate buffer size handling into lsm_fill_user_ctx() lsm: correct error codes in security_getselfattr() lsm: cleanup the size counters in security_getselfattr() lsm: don't yet account for IMA in LSM_CONFIG_COUNT calculation lsm: drop LSM_ID_IMA LSM: selftests for Linux Security Module syscalls SELinux: Add selfattr hooks AppArmor: Add selfattr hooks Smack: implement setselfattr and getselfattr hooks ... |

Prior to this patch all processes were marked as SECINITSID_KERNEL before the SELinux policy was loaded, making it difficult to distinquish early boot userspace processes from the kernel in the SELinux policy. For most users this will be a non-issue as the policy is loaded early enough during boot, but for users who load their SELinux policy relatively late, this should make it easier to construct meaningful security policies. - Cleanups to the selinuxfs code by Al, mostly on VFS related issues during a policy reload. The commit description has more detail, but the quick summary is that we are replacing a disconnected directory approach with a temporary directory that we swapover at the end of the reload. - Fix an issue where the input sanity checking on socket bind() operations was slightly different depending on the presence of SELinux. This is caused by the placement of the LSM hooks in the generic socket layer as opposed to the protocol specific bind() handler where the protocol specific sanity checks are performed. Mickaël has mentioned that he is working to fix this, but in the meantime we just ensure that we are replicating the checks properly. We need to balance the placement of the LSM hooks with the number of LSM hooks; pushing the hooks down into the protocol layers is likely not the right answer. - Update the avc_has_perm_noaudit() prototype to better match the function definition. - Migrate from using partial_name_hash() to full_name_hash() the filename transition hash table. This improves the quality of the code and has the potential for a minor performance bump. - Consolidate some open coded SELinux access vector comparisions into a single new function, avtab_node_cmp(), and use that instead. A small, but nice win for code quality and maintainability. - Updated the SELinux MAINTAINERS entry with additional information around process, bug reporting, etc. We're also updating some of our "official" roles: dropping Eric Paris and adding Ondrej as a reviewer. - Cleanup the coding style crimes in security/selinux/include. While I'm not a fan of code churn, I am pushing for more automated code checks that can be done at the developer level and one of the obvious things to check for is coding style. In an effort to start from a "good" base I'm slowly working through our source files cleaning them up with the help of clang-format and good ol' fashioned human eyeballs; this has the first batch of these changes. I've been splitting the changes up per-file to help reduce the impact if backports are required (either for LTS or distro kernels), and I expect the some of the larger files, e.g. hooks.c and ss/services.c, will likely need to be split even further. - Cleanup old, outdated comments. * tag 'selinux-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: (24 commits) selinux: Fix error priority for bind with AF_UNSPEC on PF_INET6 socket selinux: fix style issues in security/selinux/include/initial_sid_to_string.h selinux: fix style issues in security/selinux/include/xfrm.h selinux: fix style issues in security/selinux/include/security.h selinux: fix style issues with security/selinux/include/policycap_names.h selinux: fix style issues in security/selinux/include/policycap.h selinux: fix style issues in security/selinux/include/objsec.h selinux: fix style issues with security/selinux/include/netlabel.h selinux: fix style issues in security/selinux/include/netif.h selinux: fix style issues in security/selinux/include/ima.h selinux: fix style issues in security/selinux/include/conditional.h selinux: fix style issues in security/selinux/include/classmap.h selinux: fix style issues in security/selinux/include/avc_ss.h selinux: align avc_has_perm_noaudit() prototype with definition selinux: fix style issues in security/selinux/include/avc.h selinux: fix style issues in security/selinux/include/audit.h MAINTAINERS: drop Eric Paris from his SELinux role MAINTAINERS: add Ondrej Mosnacek as a SELinux reviewer selinux: remove the wrong comment about multithreaded process handling selinux: introduce an initial SID for early boot processes ... |

Pull audit updates from Paul Moore:
"The audit updates are fairly minor with only two patches:
- Send an audit ACK to userspace immediately upon receiving an auditd
registration event as opposed to waiting until the registration has
been fully processed and the audit backlog starts filling the
netlink buffers.
Sending the ACK earlier, as done here, is still safe as the
operation should not fail at the point when the ACK is done, and
doing so helps avoid the ACK being dropped in extreme situations.
- Update the audit MAINTAINERS entry with additional information.
There isn't anything in this update that should be new to regular
contributors or list subscribers, but I'm pushing to start
documenting our processes, conventions, etc. and this seems like an
important part of that"

series
"maple_tree: add mt_free_one() and mt_attr() helpers"
"Some cleanups of maple tree"
- In the series "mm: use memmap_on_memory semantics for dax/kmem"
Vishal Verma has altered the interworking between memory-hotplug
and dax/kmem so that newly added 'device memory' can more easily
have its memmap placed within that newly added memory.

Merge tag 'vfs-6.8.rw' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs rw updates from Christian Brauner:
"This contains updates from Amir for read-write backing file helpers
for stacking filesystems such as overlayfs:
- Fanotify is currently in the process of introducing pre content
events. Roughly, a new permission event will be added indicating
that it is safe to write to the file being accessed. These events
are used by hierarchical storage managers to e.g., fill the content
of files on first access.
During that work we noticed that our current permission checking is
inconsistent in rw_verify_area() and remap_verify_area().
Especially in the splice code permission checking is done multiple
times. For example, one time for the whole range and then again for
partial ranges inside the iterator.
In addition, we mostly do permission checking before we call
file_start_write() except for a few places where we call it after.
For pre-content events we need such permission checking to be done
before file_start_write(). So this is a nice reason to clean this
all up.
After this series, all permission checking is done before
file_start_write().
As part of this cleanup we also massaged the splice code a bit. We
got rid of a few helpers because we are alredy drowning in special
read-write helpers. We also cleaned up the return types for splice
helpers.
- Introduce generic read-write helpers for backing files. This lifts
some overlayfs code to common code so it can be used by the FUSE
passthrough work coming in over the next cycles. Make Amir and
Miklos the maintainers for this new subsystem of the vfs"

MAINTAINERS: use tabs for indent of CONFIDENTIAL COMPUTING THREAT MODEL
There are two MAINTAINERS entries which snuck in during the previous
merge window which use spaces instead of tabs for indent. The rest
of the file uses tabs. Fix CONFIDENTIAL COMPUTING THREAT MODEL FOR
X86 VIRTUALIZATION (SNP/TDX).
Given the prevalence of using tabs some scripts (AKA my scripts)
assume tabs when parsing.
The faulty entry was added in commit 1f597b1a6ec2 ("docs: security:
Confidential computing intro and threat model for x86 virtualization")
