Revert commit 90dc946059b7 ("selftests/bpf: DENYLIST.aarch64: Remove
fexit_sleep") again. The fix in 19d3c179a377 ("bpf, arm64: Fix trampoline
for BPF_TRAMP_F_CALL_ORIG") does not address all of the issues and BPF
CI is still hanging and timing out:
https://github.com/kernel-patches/bpf/actions/runs/9905842936/job/27366435436
[...]

#89/13 fexit_bpf2bpf/func_replace_progmap:OK
#89 fexit_bpf2bpf:OK
Error: The operation was canceled.
Thus more investigation work & fixing is needed before the test can be put
in place again.

Pull ARM SoC fixes from Arnd Bergmann:
"Most of these changes are Qualcomm SoC specific and came in just after
I sent out the last set of fixes. This includes two regression fixes
for SoC drivers, a defconfig change to ensure the Lenovo X13s is
usable and 11 changes to DT files to fix regressions and minor
platform specific issues.
Tony and Chunyan step back from their respective maintainership roles
on the omap and unisoc platforms, and Christophe in turn takes over
maintaining some of the Freescale SoC drivers that he has been taking
care of in practice already.
Lastly, there are two trivial fixes for the davinci and sunxi

Shung-Hsi Yu says:
====================
Use overflow.h helpers to check for overflows
This patch set refactors kernel/bpf/verifier.c to use type-agnostic, generic
overflow-check helpers defined in include/linux/overflow.h to check for addition
and subtraction overflow, and drop the signed_*_overflows() helpers we currently
have in kernel/bpf/verifier.c; with a fix for overflow check in adjust_jmp_off()
in patch 1.
There should be no functional change in how the verifier works and the main
motivation is to make future refactoring[1] easier.
While check_mul_overflow() also exists and could potentially replace what
we have in scalar*_min_max_mul(), it does not help with refactoring and
would either change how the verifier works (e.g. lifting restriction on
umax<=U32_MAX and u32_max<=U16_MAX) or make the code slightly harder to
read, so it is left for future endeavour.
Changes from v2 <https://lore.kernel.org/r/20240701055907.82481-1-shung-hsi.yu@suse.com>
- add fix for 5337ac4c9b80 ("bpf: Fix the corner case with may_goto and jump to
the 1st insn.") to correct the overflow check for general jump instructions
- adapt to changes in commit 5337ac4c9b80 ("bpf: Fix the corner case with
may_goto and jump to the 1st insn.")
- refactor in adjust_jmp_off() as well and remove signed_add16_overflow()
Changes from v1 <https://lore.kernel.org/r/20240623070324.12634-1-shung-hsi.yu@suse.com>:
- use pointers to values in dst_reg directly as the sum/diff pointer and
remove the else branch (Jiri)
- change local variables to be dst_reg pointers instead of src_reg values
- include comparison of generated assembly before & after the change

Similar to previous patch that drops signed_add*_overflows() and uses
(compiler) builtin-based check_add_overflow(), do the same for
signed_sub*_overflows() and replace them with the generic
check_sub_overflow() to make future refactoring easier and have the
checks implemented more efficiently.
Unsigned overflow check for subtraction does not use helpers and are
simple enough already, so they're left untouched.
After the change GCC 13.3.0 generates cleaner assembly on x86_64:

signed_add*_overflows() was added back when there was no overflow-check
helper. With the introduction of such helpers in commit f0907827a8a91
("compiler.h: enable builtin overflow checkers and add fallback code"), we
can drop signed_add*_overflows() in kernel/bpf/verifier.c and use the
generic check_add_overflow() instead.
This will make future refactoring easier, and takes advantage of
compiler-emitted hardware instructions that efficiently implement these
checks.
After the change GCC 13.3.0 generates cleaner assembly on x86_64:

Note: unlike adjust_ptr_min_max_vals() and scalar*_min_max_add(), it is
necessary to introduce intermediate variable in adjust_jmp_off() to keep
the functional behavior unchanged. Without an intermediate variable
imm/off will be altered even on overflow.

adjust_jmp_off() incorrectly used the insn->imm field for all overflow check,
which is incorrect as that should only be done or the BPF_JMP32 | BPF_JA case,
not the general jump instruction case. Fix it by using insn->off for overflow
check in the general case.

Combined with CONFIG_WERROR=y these can halt the build.
The fix (annotating the structure field with __printf())
suggested by Mirsad resolves these. Apologies I missed this last time.
No other W=1 warnings were observed in kernel/bpf after this fix.

If we encounter an error on i2c packet transmit, we won't have a valid
flow anymore; since we didn't transmit a valid packet sequence, we'll
have to wait for the key to timeout instead of dropping it on the reply.
This causes the i2c lock to be held for longer than necessary.
Instead, invalidate the flow on TX error, and release the i2c lock
immediately.

There are many generations of omaps to maintain, and I will be only active
as a hobbyist with time permitting. Let's add more maintainers to ensure
continued Linux support.
TI is interested in maintaining the active SoCs such as am3, am4 and
dra7. And the hobbyists are interested in maintaining some of the older
devices, mainly based on omap3 and 4 SoCs.
Kevin and Roger have agreed to maintain the active TI parts. Both Kevin
and Roger have been working on the omap variants for a long time, and
have a good understanding of the hardware.
Aaro and Andreas have agreed to maintain the community devices. Both Aaro
and Andreas have long experience on working with the earlier TI SoCs.
While at it, let's also change me to be a reviewer for the omap1, and
drop the link to my old omap web page.

When disabling a netconsole target, enabled_store() is called with

1. Inside the if/else block, with the target_list_lock spinlock held
2. Later, without the target_list_lock

There are a couple of places where the test script "sleep"s to wait for
some external condition to be met.
This is error prone, specially in slow systems (identified in CI by
"KSFT_MACHINE_SLOW=yes").
To fix this, add a "ovs_wait" function that tries to execute a command
a few times until it succeeds. The timeout used is set to 5s for
"normal" systems and doubled if a slow CI machine is detected.
This should make the following work:
$ vng --build \
--config tools/testing/selftests/net/config \
--config kernel/configs/debug.config
$ vng --run . --user root -- "make -C tools/testing/selftests/ \

In fact, this structure contains a flexible array at the end, but
historically its size, alignment etc., is calculated manually.
There are several instances of the structure embedded into other
structures, but also there's ongoing effort to remove them and we
could in the meantime declare &net_device properly.
Declare the array explicitly, use struct_size() and store the array
size inside the structure, so that __counted_by() can be applied.
Don't use PTR_ALIGN(), as SLUB itself tries its best to ensure the
allocated buffer is aligned to what the user expects.
Also, change its alignment from %NETDEV_ALIGN to the cacheline size
as per several suggestions on the netdev ML.

free_netdev 445 440 -5
netdev_freemem 24 - -24
alloc_netdev_mqs 1481 1450 -31
On x86_64 with several NICs of different vendors, I was never able to
get a &net_device pointer not aligned to the cacheline size after the
change.

Remove wrong EIO to EGAIN conversion and pass all errors as is.
After commit 230f3d53a547 ("i40e: remove i40e_status"), which should only
replace F/W specific error codes with Linux kernel generic, all EIO errors
suddenly started to be converted into EAGAIN which leads nvmupdate to retry
until it timeouts and sometimes fails after more than 20 minutes in the
middle of NVM update, so NVM becomes corrupted.
The bug affects users only at the time when they try to update NVM, and
only F/W versions that generate errors while nvmupdate. For example, X710DA2
with 0x8000ECB7 F/W is affected, but there are probably more...
Command for reproduction is just NVM update:
./nvmupdate64
In the log instead of:
i40e_nvmupd_exec_aq err I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_ENOMEM)
appears:
i40e_nvmupd_exec_aq err -EIO aq_err I40E_AQ_RC_ENOMEM
i40e: eeprom check failed (-5), Tx/Rx traffic disabled
The problematic code did silently convert EIO into EAGAIN which forced
nvmupdate to ignore EAGAIN error and retry the same operation until timeout.
That's why NVM update takes 20+ minutes to finish with the fail in the end.

When user submits a rxfh set command without touching XFRM_SYM_XOR,
rxfh.input_xfrm is set to RXH_XFRM_NO_CHANGE, which is equal to 0xff.
Testing if (rxfh.input_xfrm & RXH_XFRM_SYM_XOR &&
!ops->cap_rss_sym_xor_supported)
return -EOPNOTSUPP;
Will always be true on devices that don't set cap_rss_sym_xor_supported,
since rxfh.input_xfrm & RXH_XFRM_SYM_XOR is always true, if input_xfrm
was not set, i.e RXH_XFRM_NO_CHANGE=0xff, which will result in failure
of any command that doesn't require any change of XFRM, e.g RSS context
or hash function changes.
To avoid this breakage, test if rxfh.input_xfrm != RXH_XFRM_NO_CHANGE
before testing other conditions. Note that the problem will only trigger
with XFRM-aware userspace, old ethtool CLI would continue to work.

IFLA_MAX is increasing slowly but surely.
Some compilers use more than 512 bytes of stack in rtnetlink_rcv_msg()
because it calls rtnl_calcit() for RTM_GETLINK message.

and directly use nla_for_each_attr_type() (Jakub suggestion)

ethtool_get_max_rxfh_channel() gets called when user requests
deactivating Rx channels. Check the additional RSS contexts, too.

Commit 0d1b7d6c9274 ("bnxt: fix crashes when reducing ring count with
active RSS contexts") proves that allowing indirection table to contain
channels with out of bounds IDs may lead to crashes. Currently the
max channel check in the core gets skipped if driver can't fetch
the indirection table or when we can't allocate memory.
Both of those conditions should be extremely rare but if they do
happen we should try to be safe and fail the channel change.
