tracing/treewide: Remove second parameter of __assign_str()
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.
This means that with:
__string(field, mystring)
Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.
There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:
git grep -l __assign_str | while read a ; do
sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
mv /tmp/test-file $a;
done
I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.
Note, the same updates will need to be done for:
__assign_str_len()
__assign_rel_str()
__assign_rel_str_len()
I tested this with both an allmodconfig and an allyesconfig (build only for both).

Networking changes for 6.10.
Core & protocols
----------------
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd passing
functionality. New method based on Tarjan's Strongly Connected Components
algorithm should be both faster and remove a lot of workarounds
we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP packets
and forwarding them together. Useful for small switches / routers which
lack basic checksum offload in some scenarios (e.g. PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't
use NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory accounting,
RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked,
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states.
State can be used either for input or output packet processing.
Things we sprinkled into general kernel code
--------------------------------------------
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter
---------
- Use GFP_KERNEL to clone elements, to deal better with OOM situations
and avoid failures in the .commit step.
BPF
---
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. "Session mode" is a common use-case for tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw tracepoint
programs in order to ease migration from classic to raw tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V JITs.
This allows inlining functions which need to access per-CPU state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86 instruction.
Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor process-context
bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API
----------
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line) config.
- Initial bits of a queue control API, for now allowing a single queue
to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling
-----------------
- Remove the need to create a config file to run the net forwarding tests
so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test machine).
Add a few such tests.
- Create a shared code library for writing Python tests. Expose the YAML
Netlink library from tools/ to the tests for easy Netlink access.
- Move netfilter tests under net/, extend them, separate performance tests
from correctness tests, and iron out issues found by running them
"on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF info,
TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers
-------
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application rather
than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):

bus: mhi: host: pci_generic: Add generic edl_trigger to allow devices to enter EDL mode
Some of the MHI modems like SDX65 based ones are capable of entering the EDL mode as per the standard triggering mechanism defined in the MHI spec v1.2. So let's add a common mhi_pci_generic_edl_trigger() function that triggers the EDL mode in the device when user writes to the /sys/bus/mhi/devices/.../trigger_edl file. As per the spec, the EDL mode can be triggered by writing a cookie to the EDL doorbell register and then resetting the device. Devices supporting this standard way of entering EDL mode can set the mhi_pci_dev_info::edl_trigger flag.

Add sysfs entry to allow users of MHI bus to force device to enter EDL (Emergency Download) mode to download the device firmware. Since there is no guarantee that all the devices will support EDL mode, the sysfs entry is kept as an optional one and will appear only for the supported devices.

bus: mhi: host: Add mhi_power_down_keep_dev() API to support system suspend/hibernation
Currently, ath11k fails to resume from system suspend/hibernation on some
the x86 host machines with below error message:
```
ath11k_pci 0000:06:00.0: timeout while waiting for restart complete
```
This happens because, ath11k powers down the MHI stack during suspend and
that leads to destruction of the struct device associated with the MHI
channels. And during resume, ath11k calls calling mhi_sync_power_up() to
power up the MHI subsystem and that eventually calls the driver framework's
device_add() API from mhi_create_devices(). But the PM framework blocks the
struct device creation during device_add() and this leads to probe deferral
as below:
```
mhi mhi0_IPCR: Driver qcom_mhi_qrtr force probe deferral
```
The reason for deferring device creation during resume is explained in
dpm_prepare():
/*
* It is unsafe if probing of devices will happen during suspend or
* hibernation and system behavior will be unpredictable in this
* case. So, let's prohibit device's probing here and defer their
* probes instead. The normal behavior will be restored in
* dpm_complete().
*/
Due to the device probe deferral, qcom_mhi_qrtr_probe() API is not getting
called during resume and thus MHI channels are not prepared. So this blocks
the QMI messages from being transferred between ath11k and firmware,
resulting in a firmware initialization failure.
After consulting with Rafael, it was decided to not destroy the struct
device for the MHI channels during system suspend/hibernation because the
device is bound to appear again during resume.
So to achieve this, a new API called mhi_power_down_keep_dev() is
introduced for MHI controllers to keep the struct device when required.
This API is similar to the existing mhi_power_down() API, except that it
keeps the struct device associated with MHI channels instead of destroying
them.

Char/Misc and other driver subsystem updates for 6.9-rc1
Here is the big set of char/misc and a number of other driver subsystem
updates for 6.9-rc1. Included in here are:
- IIO driver updates, loads of new ones and evolution of existing ones
- coresight driver updates
- const cleanups for many driver subsystems
- speakup driver additions
- platform remove callback void cleanups
- mei driver updates
- mhi driver updates
- cdx driver updates for MSI interrupt handling
- nvmem driver updates
- other smaller driver updates and cleanups, full details in the
shortlog
All of these have been in linux-next for a long time with no reported
issue, other than a build warning with some older versions of gcc for a
speakup driver, fix for that will come in a few days when I catch up
with my pending patch queues.

ARM: late SoC changes for 6.9
These are changes that for some reason ended up not making it into the
first four branches but that should still make it into 6.9:
- A rework of the omap clock support that touches both drivers and
device tree files
- The reset controller branch changes that had a dependency on late
bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
drivers branch
- The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree
changes that got delayed and needed some extra time in linux-next
for wider testing.

ARM: SoC drivers for 6.9
This is the usual mix of updates for drivers that are used on (mostly
ARM) SoCs with no other top-level subsystem tree, including:
- The SCMI firmware subsystem gains support for version 3.2 of the
specification and updates to the notification code.
- Feature updates for Tegra and Qualcomm platforms for added
hardware support.
- A number of platforms get soc_device additions for identifying newly
added chips from Renesas, Qualcomm, Mediatek and Google.
- Trivial improvements for firmware and memory drivers amongst
others, in particular 'const' annotations throughout multiple
subsystems.

bus: imx-weim: fix valid range check
When the range parsing was open-coded the number of u32 entries to
parse had to be a multiple of 4 and the driver checks this. With
the range parsing converted to the range parser the counting changes
from individual u32 entries to a complete range, so the check must
not reject counts not divisible by 4.

bus: mhi: ep: Use kcalloc() instead of kzalloc()
This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1]. Here the multiplication is obviously safe because the "event_rings" member never can have a value greater than 255 (8 bits). This member is set twice using always FIELD_GET: mhi_cntrl->event_rings = FIELD_GET(MHICFG_NER_MASK, regval); mhi_cntrl->event_rings = FIELD_GET(MHICFG_NER_MASK, regval); And the MHICFG_NER_MASK macro defines the 8 bits mask that guarantees a maximum value of 255. However, using kcalloc() is more appropriate [1] and improves readability. This patch has no effect on runtime behavior.

bus: mhi: host: Read PK HASH dynamically
The OEM PK HASH registers in the BHI region are read once during firmware load (boot), cached, and displayed on demand via sysfs. This has a few problems - if firmware load is skipped, the registers will not be read and if the register values change over the life of the device the local cache will be out of sync. Qualcomm Cloud AI 100 can expose both these problems. It is possible for mhi_async_power_up() to be invoked while the device is in AMSS EE, which would bypass firmware loading. Also, Qualcomm Cloud AI 100 has 5 PK HASH slots which can be dynamically provisioned while the device is active, which would result in the values changing and users may want to know what keys are active. Address these concerns by reading the PK HASH registers on-demand during the sysfs read. This will result in showing the most current information.

bus: mhi: host: Add MHI_PM_SYS_ERR_FAIL state
When processing a SYSERR, if the device does not respond to the MHI_RESET from the host, the host will be stuck in a difficult to recover state. The host will remain in MHI_PM_SYS_ERR_PROCESS and not clean up the host channels. Clients will not be notified of the SYSERR via the destruction of their channel devices, which means clients may think that the device is still up. Subsequent SYSERR events such as a device fatal error will not be processed as the state machine cannot transition from PROCESS back to DETECT. The only way to recover from this is to unload the mhi module (wipe the state machine state) or for the mhi controller to initiate SHUTDOWN. This issue was discovered by stress testing soc_reset events on AIC100 via the sysfs node. soc_reset is processed entirely in hardware. When the register write hits the endpoint hardware, it causes the soc to reset without firmware involvement. In stress testing, there is a rare race where soc_reset N will cause the soc to reset and PBL to signal SYSERR (fatal error). If soc_reset N+1 is triggered before PBL can process the MHI_RESET from the host, then the soc will reset again, and re-run PBL from the beginning. This will cause PBL to lose all state. PBL will be waiting for the host to respond to the new syserr, but host will be stuck expecting the previous MHI_RESET to be processed. Additionally, the AMSS EE firmware (QSM) was hacked to synthetically reproduce the issue by simulating a FW hang after the QSM issued a SYSERR. In this case, soc_reset would not recover the device. For this failure case, to recover the device, we need a state similar to PROCESS, but can transition to DETECT. There is not a viable existing state to use. POR has the needed transitions, but assumes the device is in a good state and could allow the host to attempt to use the device. Allowing PROCESS to transition to DETECT invites the possibility of parallel SYSERR processing which could get the host and device out of sync. Thus, invent a new state - MHI_PM_SYS_ERR_FAIL This essentially a holding state. It allows us to clean up the host elements that are based on the old state of the device (channels), but does not allow us to directly advance back to an operational state. It does allow the detection and processing of another SYSERR which may recover the device, or allows the controller to do a clean shutdown.

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
