Disable cesa hash algorithms by lowering the priority because they
appear to be broken when invoked in parallel. This allows them to
still be tested for debugging purposes.

Use the generic crypto_authenc_extractkeys helper instead of custom
parsing code that is slightly broken. Also fix a number of memory
leaks by moving memory allocation from setkey to init_tfm (setkey
can be called multiple times over the life of a tfm).
Finally accept all hash key lengths by running the digest over
extra-long keys.

The custom swap functions used in octeontx2 driver do not perform any
special operations and can be replaced with the built-in swap function
of sort. This change not only reduces code size but also improves
efficiency, especially in scenarios where CONFIG_RETPOLINE is enabled,
as it makes indirect function calls more expensive.
By using the built-in swap, we avoid these costly indirect function
calls, leading to better performance.

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):

There are limited number CPT LFs (example 64 LFs on cn10k) and
these LFs are allocated/attached to CPT VF on its creation.
cptpf sysfs parameter "kvf_limits" defines number of CPT LFs
per CPT VF. Default "kvf_limits" is initialized to zero and if
kvf_limits is zero then number of LF allocated are equal to
online cpus in system.
For example on 24 core system, 24 CPT LFs will be attached per VF.
That means no CPT LF available when creating more than 2 CPT VFs
on system which have total 64 LFs. Although VFs gets created but
no LF attached to it.
There seems no reason to default allocate as many LFs as many
online cpus in system. This patch initializes "kvf_limits" to
one to limit one LF allocated per CPT VF. "kvf_limits" can
be changed in range of 1 to number-of-online-cpus via sysfs.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

BACKGROUND
==========
When multiple work items are queued to a workqueue, their execution order
doesn't match the queueing order. They may get executed in any order and
simultaneously. When fully serialized execution - one by one in the queueing
order - is needed, an ordered workqueue should be used which can be created
with alloc_ordered_workqueue().
However, alloc_ordered_workqueue() was a later addition. Before it, an
ordered workqueue could be obtained by creating an UNBOUND workqueue with
@max_active==1. This originally was an implementation side-effect which was
broken by 4c16bd327c ("workqueue: restore WQ_UNBOUND/max_active==1 to be
ordered"). Because there were users that depended on the ordered execution,
5c0338c687 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered")
made workqueue allocation path to implicitly promote UNBOUND workqueues w/
@max_active==1 to ordered workqueues.
While this has worked okay, overloading the UNBOUND allocation interface
this way creates other issues. It's difficult to tell whether a given
workqueue actually needs to be ordered and users that legitimately want a
min concurrency level wq unexpectedly gets an ordered one instead. With
planned UNBOUND workqueue updates to improve execution locality and more
prevalence of chiplet designs which can benefit from such improvements, this
isn't a state we wanna be in forever.
This patch series audits all callsites that create an UNBOUND workqueue w/
@max_active==1 and converts them to alloc_ordered_workqueue() as necessary.
WHAT TO LOOK FOR
================
The conversions are from
alloc_workqueue(WQ_UNBOUND | flags, 1, args..)
to
alloc_ordered_workqueue(flags, args...)
which don't cause any functional changes. If you know that fully ordered
execution is not ncessary, please let me know. I'll drop the conversion and
instead add a comment noting the fact to reduce confusion while conversion
is in progress.
If you aren't fully sure, it's completely fine to let the conversion
through. The behavior will stay exactly the same and we can always
reconsider later.
As there are follow-up workqueue core changes, I'd really appreciate if the
patch can be routed through the workqueue tree w/ your acks. Thanks.

On OcteonTX2/OctoenTX3 variants of silicon, Admin function (AF)
handles resource allocation and configuration for PFs and their VFs.
PFs request the AF directly, via mailboxes.
Unlike PFs, VFs cannot send a mailbox request directly. A VF sends
mailbox messages to its parent PF, with which it shares a
mailbox region. The PF then forwards these messages to the AF.
This patch adds code to configure inline-IPsec HW resources for
CPT VFs as CPT VFs cannot send a mailbox request directly to AF.

Despite they're build under the same Kconfig option
(CONFIG_CRYPTO_DEV_OCTEONTX2_CPT), it's better do link the common
code into a standalone module and export the shared functions. Under
certain circumstances, this can lead to the same situation as fixed
by commit 637a642f5c ("zstd: Fixing mixed module-builtin objects").
Plus, those three common object files are relatively big to duplicate
them several times.
Introduce the new module, rvu_cptcommon, to provide the common

The "code_length" value comes from the firmware file. If your firmware
is untrusted realistically there is probably very little you can do to
protect yourself. Still we try to limit the damage as much as possible.
Also Smatch marks any data read from the filesystem as untrusted and
prints warnings if it not capped correctly.
The "code_length * 2" can overflow. The round_up(ucode_size, 16) +
sizeof() expression can overflow too. Prevent these overflows.
