9e87705289 Initial bcachefs pull request for 6.7-rc1
Here's the bcachefs filesystem pull request.
 
 One new patch since last week: the exportfs constants ended up
 conflicting with other filesystems that are also getting added to the
 global enum, so switched to new constants picked by Amir.
 
 I'll also be sending another pull request later on in the cycle bringing
 things up to date my master branch that people are currently running;
 that will be restricted to fs/bcachefs/, naturally.
 
 Testing - fstests as well as the bcachefs specific tests in ktest:
   https://evilpiepirate.org/~testdashboard/ci?branch=bcachefs-for-upstream
 
 It's also been soaking in linux-next, which resulted in a whole bunch of
 smatch complaints and fixes and a patch or two from Kees.
 
 The only new non fs/bcachefs/ patch is the objtool patch that adds
 bcachefs functions to the list of noreturns. The patch that exports
 osq_lock() has been dropped for now, per Ingo.
 
 Prereq patch list:
 
 faf1dce85275 objtool: Add bcachefs noreturns
 73badee4280c lib/generic-radix-tree.c: Add peek_prev()
 9492261ff246 lib/generic-radix-tree.c: Don't overflow in peek()

72d091846d kbuild: avoid too many execution of scripts/pahole-flags.sh
scripts/pahole-flags.sh is executed so many times.

You can confirm it, as follows:

  $ cat <<EOF >> scripts/pahole-flags.sh
  > echo "scripts/pahole-flags.sh was executed" >&2
  > EOF

  $ make -s
  scripts/pahole-flags.sh was executed
  scripts/pahole-flags.sh was executed
  scripts/pahole-flags.sh was executed
  scripts/pahole-flags.sh was executed
  scripts/pahole-flags.sh was executed
    [ lots of repeated lines... ]

This scripts is executed more than 20 times during the kernel build
because PAHOLE_FLAGS is a recursively expanded variable and exported
to sub-processes.

With GNU Make >= 4.4, it is executed more than 60 times because
exported variables are also passed to other $(shell ) invocations.
Without careful coding, it is known to cause an exponential fork
explosion. [1]

The use of $(shell ) in an exported recursive variable is likely wrong
because $(shell ) is always evaluated due to the 'export' keyword, and
the evaluation can occur multiple times by the nature of recursive
variables.

Convert the shell script to a Makefile, which is included only when
CONFIG_DEBUG_INFO_BTF=y.

a103f46633 acpi: Move common tables helper functions to common lib
Some of the routines in ACPI driver/acpi/tables.c can be shared with
parsing CDAT. CDAT is a device-provided data structure that is formatted
similar to a platform provided ACPI table. CDAT is used by CXL and can
exist on platforms that do not use ACPI. Split out the common routine
from ACPI to accommodate platforms that do not support ACPI and move that
to /lib. The common routines can be built outside of ACPI if
FIRMWARE_TABLES is selected.

Mikulas is a long-time contributor to the DM subsystem and has
effectively been a shadow DM maintainer.  It is time to formally
name Mikulas as a DM maintainer.

In practice this doesn't imply any process changes for DM maintenance
(Mikulas can still just feed changes and contribute review like
normal).

This change does allow the possibility for Mikulas to take on more

ec558bbfea greybus: Add BeaglePlay Linux Driver
Add the Greybus host driver for BeaglePlay board by BeagleBoard.org.

The current greybus setup involves running SVC in a user-space
application (GBridge) and using netlink to communicate with kernel
space. GBridge itself uses wpanusb kernel driver, so the greybus messages
travel from kernel space (gb_netlink) to user-space (GBridge) and then
back to kernel space (wpanusb) before reaching CC1352.

This driver directly communicates with CC1352 (running SVC Zephyr
application). Thus, it simplifies the complete greybus setup eliminating
user-space GBridge.

This driver is responsible for the following:
- Start SVC (CC1352) on driver load.
- Send/Receive Greybus messages to/from CC1352 using HDLC over UART.
- Print Logs from CC1352.
- Stop SVC (CC1352) on driver load.

efc3d7d203 ALSA: scarlett2: Rename scarlett_gen2 to scarlett2
This driver was originally developed for the Focusrite Scarlett Gen 2
series. Since then Focusrite have used a similar protocol for their
Gen 3, Gen 4, Clarett USB, Clarett+, and Vocaster series.

Let's call this common protocol the "Scarlett 2 Protocol" and rename
the driver to scarlett2 to not imply that it is restricted to Gen 2
series devices.

pull-request: bpf-next 2023-10-26

We've added 51 non-merge commits during the last 10 day(s) which contain
a total of 75 files changed, 5037 insertions(+), 200 deletions(-).

The main changes are:

1) Add open-coded task, css_task and css iterator support.
   One of the use cases is customizable OOM victim selection via BPF,
   from Chuyi Zhou.

2) Fix BPF verifier's iterator convergence logic to use exact states
   comparison for convergence checks, from Eduard Zingerman,
   Andrii Nakryiko and Alexei Starovoitov.

3) Add BPF programmable net device where bpf_mprog defines the logic
   of its xmit routine. It can operate in L3 and L2 mode,
   from Daniel Borkmann and Nikolay Aleksandrov.

4) Batch of fixes for BPF per-CPU kptr and re-enable unit_size checking
   for global per-CPU allocator, from Hou Tao.

5) Fix libbpf which eagerly assumed that SHT_GNU_verdef ELF section
   was going to be present whenever a binary has SHT_GNU_versym section,
   from Andrii Nakryiko.

6) Fix BPF ringbuf correctness to fold smp_mb__before_atomic() into
   atomic_set_release(), from Paul E. McKenney.

7) Add a warning if NAPI callback missed xdp_do_flush() under
   CONFIG_DEBUG_NET which helps checking if drivers were missing
   the former, from Sebastian Andrzej Siewior.

8) Fix missed RCU read-lock in bpf_task_under_cgroup() which was throwing
   a warning under sleepable programs, from Yafang Shao.

9) Avoid unnecessary -EBUSY from htab_lock_bucket by disabling IRQ before
   checking map_locked, from Song Liu.

10) Make BPF CI linked_list failure test more robust,
    from Kumar Kartikeya Dwivedi.

11) Enable samples/bpf to be built as PIE in Fedora, from Viktor Malik.

12) Fix xsk starving when multiple xsk sockets were associated with
    a single xsk_buff_pool, from Albert Huang.

13) Clarify the signed modulo implementation for the BPF ISA standardization
    document that it uses truncated division, from Dave Thaler.

14) Improve BPF verifier's JEQ/JNE branch taken logic to also consider
    signed bounds knowledge, from Andrii Nakryiko.

15) Add an option to XDP selftests to use multi-buffer AF_XDP
    xdp_hw_metadata and mark used XDP programs as capable to use frags,
    from Larysa Zaremba.

16) Fix bpftool's BTF dumper wrt printing a pointer value and another
    one to fix struct_ops dump in an array, from Manu Bretelle.

3a568e3a96 ARM: SoC fixes for 6.7, part 3
A couple of platforms have some last-minute fixes for 6.7, in particular
 
  - riscv gets some fixes for noncoherent DMA on the renesas and thead
    platforms and dts fix for SPI on the visionfive 2 board
 
  - Qualcomm Snapdragon gets three dts fixes to address board specific
    regressions on the pmic and gpio nodes
 
  - Rockchip platforms get multiple dts fixes to address issues on
    the recent rk3399 platform as well as the older rk3128 platform
    that apparently regressed a while ago.
 
  - TI OMAP gets some trivial code and dts fixes and a regression fix
    for the omap1 ams-delta modem
 
  - NXP i.MX firmware has one fix for a use-after-free but in its
    error handling.

53313ed25b dt-bindings: marvell: Add Marvell MV88E6060 DSA schema
The Marvell MV88E6060 is one of the oldest DSA switches from
Marvell, and it has DT bindings used in the wild. Let's define
them properly.

It is different enough from the rest of the MV88E6xxx switches
that it deserves its own binding.

0f35369b4e dt-bindings: marvell: Rewrite MV88E6xxx in schema
This is an attempt to rewrite the Marvell MV88E6xxx switch bindings
in YAML schema.

The current text binding says:
  WARNING: This binding is currently unstable. Do not program it into a
  FLASH never to be changed again. Once this binding is stable, this
  warning will be removed.

Well that never happened before we switched to YAML markup,
we can't have it like this, what about fixing the mess?

35dfaad718 netkit, bpf: Add bpf programmable net device
This work adds a new, minimal BPF-programmable device called "netkit"
(former PoC code-name "meta") we recently presented at LSF/MM/BPF. The
core idea is that BPF programs are executed within the drivers xmit routine
and therefore e.g. in case of containers/Pods moving BPF processing closer
to the source.

One of the goals was that in case of Pod egress traffic, this allows to
move BPF programs from hostns tcx ingress into the device itself, providing
earlier drop or forward mechanisms, for example, if the BPF program
determines that the skb must be sent out of the node, then a redirect to
the physical device can take place directly without going through per-CPU
backlog queue. This helps to shift processing for such traffic from softirq
to process context, leading to better scheduling decisions/performance (see
measurements in the slides).

In this initial version, the netkit device ships as a pair, but we plan to
extend this further so it can also operate in single device mode. The pair
comes with a primary and a peer device. Only the primary device, typically
residing in hostns, can manage BPF programs for itself and its peer. The
peer device is designated for containers/Pods and cannot attach/detach
BPF programs. Upon the device creation, the user can set the default policy
to 'pass' or 'drop' for the case when no BPF program is attached.

Additionally, the device can be operated in L3 (default) or L2 mode. The
management of BPF programs is done via bpf_mprog, so that multi-attach is
supported right from the beginning with similar API and dependency controls
as tcx. For details on the latter see commit 053c8e1f235d ("bpf: Add generic
attach/detach/query API for multi-progs"). tc BPF compatibility is provided,
so that existing programs can be easily migrated.

Going forward, we plan to use netkit devices in Cilium as the main device
type for connecting Pods. They will be operated in L3 mode in order to
simplify a Pod's neighbor management and the peer will operate in default
drop mode, so that no traffic is leaving between the time when a Pod is
brought up by the CNI plugin and programs attached by the agent.
Additionally, the programs we attach via tcx on the physical devices are
using bpf_redirect_peer() for inbound traffic into netkit device, hence the
latter is also supporting the ndo_get_peer_dev callback. Similarly, we use
bpf_redirect_neigh() for the way out, pushing from netkit peer to phys device
directly. Also, BIG TCP is supported on netkit device. For the follow-up
work in single device mode, we plan to convert Cilium's cilium_host/_net
devices into a single one.

An extensive test suite for checking device operations and the BPF program
and link management API comes as BPF selftests in this series.

bdac188ec3 firmware: qcom: move Qualcomm code into its own directory
We're getting more and more qcom specific .c files in drivers/firmware/
and about to get even more. Create a separate directory for Qualcomm
firmware drivers and move existing sources in there.

875be09092 staging: qlge: Retire the driver
No significant improvements have been done to this driver since commit
a7c3ddf29a78 ("staging: qlge: clean up debugging code in the QL_ALL_DUMP
ifdef land") in January 2021. The driver should not stay in staging
forever. Since it has been abandoned by the vendor and no one has stepped
up to maintain it, delete it.

If some users manifest themselves, the driver will be restored to
drivers/net/ as suggested in the linked message.

39cd06e3f7 ASoC: Updates for v6.7
This is quite a large set of changes but mostly due to API cleanups and
 in driver specific ways rather than due to anything subsystem wide.
 Highlights include:
 
  - Standardisation of API prefixes on snd_soc_, removing asoc_.
  - GPIO API usage improvements.
  - Support for HDA patches.
  - Lots of work on SOF, including crash dump support.
  - Support for AMD platforms with es83xx, Awinc AT87390, many Intel
    platforms, many Mediatek platforms, Qualcomm SM6115,  Richtek RTQ9128
    and Texas Instruments TAS575x.
