When r8169 is built-in but LED support is a loadable module, the new
code to drive the LED causes a link failure:
ld: drivers/net/ethernet/realtek/r8169_leds.o: in function `rtl8168_init_leds':
r8169_leds.c:(.text+0x36c): undefined reference to `devm_led_classdev_register_ext'
LED support is an optional feature, so fix this issue by adding a Kconfig
symbol R8169_LEDS that is guaranteed to be false if r8169 is built-in
and LED core support is a module. As a positive side effect of this change
r8169_leds.o no longer is built under this configuration.

The driver code proper is handled by the lynx_pcs. The enetc just needs
to populate phylink's supported_interfaces array, and return true for
this phy-mode in enetc_port_has_pcs(), such that it creates an internal
MDIO bus through which the Lynx PCS registers are accessed.

"Including fixes from wireless and netfilter.
We haven't accumulated much over the break. If it wasn't for the

Commit 688eb8191b47 ("x86/csum: Improve performance of `csum_partial`")
ended up improving the code generation for the IP csum calculations, and
in particular special-casing the 40-byte case that is a hot case for
IPv6 headers.
It then had _another_ special case for the 64-byte unrolled loop, which
did two chains of 32-byte blocks, which allows modern CPU's to improve
performance by doing the chains in parallel thanks to renaming the carry
flag.
This just unifies the special cases and combines them into just one
single helper the 40-byte csum case, and replaces the 64-byte case by a
80-byte case that just does that single helper twice. It avoids having
all these different versions of inline assembly, and actually improved
performance further in my tests.
There was never anything magical about the 64-byte unrolled case, even
though it happens to be a common size (and typically is the cacheline
size).

The special case for odd aligned buffers is unnecessary and mostly
just adds overhead. Aligned buffers is the expectations, and even for
unaligned buffer, the only case that was helped is if the buffer was
1-byte from word aligned which is ~1/7 of the cases. Overall it seems
highly unlikely to be worth to extra branch.
It was left in the previous perf improvement patch because I was
erroneously comparing the exact output of `csum_partial(...)`, but
really we only need `csum_fold(csum_partial(...))` to match so its
safe to remove.
All csum kunit tests pass.

s390/bpf: Fix gotol with large offsets
Hi,
While looking at a pyperf180 failure on s390x (must be related to [1],
I'm not done with the investigation yet) I noticed that I have
unfortunately messed up the gotol implementation. Patch 1 is the fix,
patch 2 is a small test infrastructure tweak, and patch 3 adds a
test.
[1] https://github.com/llvm/llvm-project/issues/55669
Best regards,
Ilya

Testing long jumps requires having >32k instructions. That many
instructions require the verifier log buffer of 2 megabytes.
The regular test_progs run doesn't need an increased buffer, since
gotol test with 40k instructions doesn't request a log,
but test_progs -v will set the verifier log level.
Hence to avoid breaking gotol test with -v increase the buffer size.

gitolite.kernel.org:pub/scm/linux/kernel/git/wpan/wpan-next
Miquel Raynal says:
====================
This pull request mainly brings support for dynamic associations in
the WPAN world. Thanks to the recent improvements it was possible to
discover nearby devices, it is now also possible to associate with them
to form a sub-network using a specific PAN ID. The support includes
several functions, such as:
* Requesting an association to a coordinator, waiting for the response
* Sending a disassociation notification to a coordinator
* Receiving an association request when we are coordinator, answering
the request (for now all devices are accepted up to a limit, to be
refined)
* Sending a disassociation notification to a child
* Users may request the list of associated devices (the parent and the
children).
Here are a few example of userspace calls that can be made:
# iwpan dev <dev> associate pan_id 2 coord $COORD
# iwpan dev <dev> list_associations
# iwpan dev <dev> disassociate ext_addr $COORD
There are as well two patches from Uwe turning remove callbacks into
void functions.

bpfilter was supposed to convert iptables filtering rules into
BPF programs on the fly, from the kernel, through a usermode
helper. The base code for the UMH was introduced in 2018, and
couple of attempts (2, 3) tried to introduce the BPF program
generate features but were abandoned.
bpfilter now sits in a kernel tree unused and unusable, occasionally
causing confusion amongst Linux users (4, 5).
As bpfilter is now developed in a dedicated repository on GitHub (6),
it was suggested a couple of times this year (LSFMM/BPF 2023,
LPC 2023) to remove the deprecated kernel part of the project. This
is the purpose of this patch.

After merging the patch set [1] to reduce memory usage
for bpf_global_percpu_ma, Alexei found a redundant check (cpu == 0)
in function bpf_mem_alloc_percpu_unit_init() ([2]).
Indeed, the check is unnecessary since c->unit_size will
be all NULL or all non-NULL for all cpus before
for_each_possible_cpu() loop.
Removing the check makes code less confusing.

User won't care about inproper hash options in the TCP header if they
don't use neither TCP-AO nor TCP-MD5. Yet, those logs can add up in
syslog, while not being a real concern to the host admin:
> kernel: TCP: TCP segment has incorrect auth options set for XX.20.239.12.54681->XX.XX.90.103.80 [S]
Keep silent and avoid logging when there aren't any keys in the system.
Side-note: I also defined static_branch_tcp_*() helpers to avoid more
ifdeffery, going to remove more ifdeffery further with their help.

This reverts commit b28ff7a7c3245d7f62acc20f15b4361292fe4117.
The commit introduced P2SB device scan and resource cache during the
boot process to avoid deadlock. But it caused detection failure of
IDE controllers on old systems [1]. The IDE controllers on old systems
and P2SB devices on newer systems have same PCI DEVFN. It is suspected
the confusion between those two is the failure cause. Revert the change
at this moment until the proper solution gets ready.

Luiz Angelo Daros de Luca reports that the MDIO bus code maintains a
reference to the DT node, but does not hold a refcount on the node.
The simple solution to this is to add the necessary refcounting into
the MDIO bus code for all users, ensuring that on registration, the
refcount is incremented, and only dropped when the MDIO bus is
released.
Do this for fwnodes, so we not only fix this for DT, but also other
types of firmware nodes as well.

CSR.OPS bits specify the current operating mode and (according to
documentation) they are updated by HW when the operating mode change
request is processed. To comply with this check CSR.OPS before proceeding.
Commit introduces ravb_set_opmode() that does all the necessities for
setting the operating mode (set CCC.OPC (and CCC.GAC, CCC.CSEL, if any) and
wait for CSR.OPS) and call it where needed. This should comply with all the
HW manuals requirements as different manual variants specify that different
modes need to be checked in CSR.OPS when setting CCC.OPC.
If gPTP active in config mode is supported and it needs to be enabled, the
CCC.GAC and CCC.CSEL needs to be configured along with CCC.OPC in the same
write access. For this, ravb_set_opmode() allows passing GAC and CSEL as
part of opmode and the function updates accordingly CCC register.

During QoS scheduling testing with multiple strict priority flows, the

queue doesn't get a chance to transmit the packets because other high
priority flows are completely subscribing the transmit link. The netdev
tx watchdog timeout routine will stop MAC RX and TX functionality in
otx2_stop() routine before cleanup of HW TX queues which results in SMQ
flush errors because the packets belonging to low priority queues will
never gets flushed since MAC TX is disabled. This patch fixes the issue
by re-enabling MAC TX to ensure the packets in HW pipeline gets flushed

Currently the NIX TX link credits are initialized based on the max frame
size that can be transmitted on a link but when the MTU is changed, the
NIX TX link credits are reprogrammed by the SW based on the new MTU value.
Since SMQ max packet length is programmed to max frame size by default,
there is a chance that NIX TX may stall while sending a max frame sized
packet on the link with insufficient credits to send the packet all at
once. This patch avoids stall issue by not changing the link credits
dynamically when the MTU is changed.

Andrii Nakryiko says:
====================
Libbpf-side __arg_ctx fallback support
Support __arg_ctx global function argument tag semantics even on older kernels
that don't natively support it through btf_decl_tag("arg:ctx").
Patches #2-#6 are preparatory work to allow to postpone BTF loading into the
kernel until after all the BPF program relocations (including global func
appending to main programs) are done. Patch #4 is perhaps the most important
and establishes pre-created stable placeholder FDs, so that relocations can
embed valid map FDs into ldimm64 instructions.
Once BTF is done after relocation, what's left is to adjust BTF information to
have each main program's copy of each used global subprog to point to its own
adjusted FUNC -> FUNC_PROTO type chain (if they use __arg_ctx) in such a way
as to satisfy type expectations of BPF verifier regarding the PTR_TO_CTX
argument definition. See patch #8 for details.
Patch #8 adds few more __arg_ctx use cases (edge cases like multiple arguments
having __arg_ctx, etc) to test_global_func_ctx_args.c, to make it simple to
validate that this logic indeed works on old kernels. It does. But just to be
100% sure patch #9 adds a test validating that libbpf uploads func_info with
properly modified BTF data.
v2->v3:
- drop renaming patch (Alexei, Eduard);
- use memfd_create() instead of /dev/null for placeholder FD (Eduard);
- add one more test for validating BTF rewrite logic (Eduard);
- fixed wrong -errno usage, reshuffled some BTF rewrite bits (Eduard);
v1->v2:
- do internal functions renaming in patch #1 (Alexei);
- extract cloning of FUNC -> FUNC_PROTO information into separate function
(Alexei);

Add a few extra cases of global funcs with context arguments. This time
rely on "arg:ctx" decl_tag (__arg_ctx macro), but put it next to
"classic" cases where context argument has to be of an exact type that
BPF verifier expects (e.g., bpf_user_pt_regs_t for kprobe/uprobe).
Colocating all these cases separately from other global func args that
rely on arg:xxx decl tags (in verifier_global_subprogs.c) allows for
simpler backwards compatibility testing on old kernels. All the cases in
test_global_func_ctx_args.c are supposed to work on older kernels, which
was manually validated during development.

Out of all special global func arg tag annotations, __arg_ctx is
practically is the most immediately useful and most critical to have
working across multitude kernel version, if possible. This would allow
end users to write much simpler code if __arg_ctx semantics worked for
older kernels that don't natively understand btf_decl_tag("arg:ctx") in
verifier logic.
Luckily, it is possible to ensure __arg_ctx works on old kernels through
a bit of extra work done by libbpf, at least in a lot of common cases.
To explain the overall idea, we need to go back at how context argument
was supported in global funcs before __arg_ctx support was added. This
was done based on special struct name checks in kernel. E.g., for
BPF_PROG_TYPE_PERF_EVENT the expectation is that argument type `struct
bpf_perf_event_data *` mark that argument as PTR_TO_CTX. This is all
good as long as global function is used from the same BPF program types
only, which is often not the case. If the same subprog has to be called
from, say, kprobe and perf_event program types, there is no single
definition that would satisfy BPF verifier. Subprog will have context
argument either for kprobe (if using bpf_user_pt_regs_t struct name) or
perf_event (with bpf_perf_event_data struct name), but not both.
This limitation was the reason to add btf_decl_tag("arg:ctx"), making
the actual argument type not important, so that user can just define
"generic" signature:
__noinline int global_subprog(void *ctx __arg_ctx) { ... }
I won't belabor how libbpf is implementing subprograms, see a huge
comment next to bpf_object_relocate_calls() function. The idea is that
each main/entry BPF program gets its own copy of global_subprog's code
appended.
This per-program copy of global subprog code *and* associated func_info
.BTF.ext information, pointing to FUNC -> FUNC_PROTO BTF type chain
allows libbpf to simulate __arg_ctx behavior transparently, even if the
kernel doesn't yet support __arg_ctx annotation natively.
The idea is straightforward: each time we append global subprog's code
and func_info information, we adjust its FUNC -> FUNC_PROTO type
information, if necessary (that is, libbpf can detect the presence of
btf_decl_tag("arg:ctx") just like BPF verifier would do it).
The rest is just mechanical and somewhat painful BTF manipulation code.
It's painful because we need to clone FUNC -> FUNC_PROTO, instead of
reusing it, as same FUNC -> FUNC_PROTO chain might be used by another
main BPF program within the same BPF object, so we can't just modify it
in-place (and cloning BTF types within the same struct btf object is
painful due to constant memory invalidation, see comments in code).
Uploaded BPF object's BTF information has to work for all BPF
programs at the same time.
Once we have FUNC -> FUNC_PROTO clones, we make sure that instead of
using some `void *ctx` parameter definition, we have an expected `struct
bpf_perf_event_data *ctx` definition (as far as BPF verifier and kernel
is concerned), which will mark it as context for BPF verifier. Same
global subprog relocated and copied into another main BPF program will
get different type information according to main program's type. It all
works out in the end in a completely transparent way for end user.
Libbpf maintains internal program type -> expected context struct name
mapping internally. Note, not all BPF program types have named context
struct, so this approach won't work for such programs (just like it
didn't before __arg_ctx). So native __arg_ctx is still important to have
in kernel to have generic context support across all BPF program types.

Move the logic of finding and assigning exception callback indices from
BTF sanitization step to program relocations step, which seems more
logical and will unblock moving BTF loading to after relocation step.
Exception callbacks discovery and assignment has no dependency on BTF
being loaded into the kernel, it only uses BTF information. It does need
to happen before subprogram relocations happen, though. Which is why the
split.
No functional changes.
