We're stuck supporting scalar misaligned loads in userspace because they
were part of the ISA at the time we froze the uABI.  That wasn't the
case for vector misaligned accesses, so depending on them
unconditionally is a userspace bug.  All extant vector hardware traps on
these misaligned accesses.

Top of the kernel thread stack should be reserved for pt_regs. However
this is not the case for the idle threads of the secondary boot harts.
Their stacks overlap with their pt_regs, so both may get corrupted.

Similar issue has been fixed for the primary hart, see c7cdd96e
("riscv: prevent stack corruption by reserving task_pt_regs(p) early").
However that fix was not propagated to the secondary harts. The problem
has been noticed in some CPU hotplug tests with V enabled. The function
smp_callin stored several registers on stack, corrupting top of pt_regs
structure including status field. As a result, kernel attempted to save
or restore inexistent V context.

Recent commit 0cfe71f4 ("netdev: add queue stats") added
a lot of useful stats, but only those immediately needed by virtio.
Presumably virtio does not support CHECKSUM_COMPLETE,
so statistic for that form of checksumming wasn't included.
Other drivers will definitely need it, in fact we expect it
to be needed in net-next soon (mlx5). So let's add the definition
of the counter for CHECKSUM_COMPLETE to uAPI in net already,
so that the counters are in a more natural order (all subsequent
counters have not been present in any released kernel, yet).

Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

Patch #1 syzbot reports that nf_reinject() could be called without
         rcu_read_lock() when flushing pending packets at nfnetlink
         queue removal, from Eric Dumazet.

Patch #2 flushes ipset list:set when canceling garbage collection to
         reference to other lists to fix a race, from Jozsef Kadlecsik.

Patch #3 restores q-in-q matching with nft_payload by reverting
         f6ae9f12 ("netfilter: nft_payload: add C-VLAN support").

Patch #4 fixes vlan mangling in skbuff when vlan offload is present
         in skbuff, without this patch nft_payload corrupts packets
         in this case.

Patch #5 fixes possible nul-deref in tproxy no IP address is found in
         netdevice, reported by syzbot and patch from Florian Westphal.

Patch #6 removes a superfluous restriction which prevents loose fib
         lookups from input and forward hooks, from Eric Garver.

My assessment is that patches #1, #2 and #5 address possible kernel
crash, anything else in this batch fixes broken features.

The driver overrides the NUMA node id of the device regardless of
whether it knows its correct value (often setting it to -1 even though
the node id is advertised in 'struct device'). This can lead to
suboptimal configurations.

This patch fixes this behavior and makes the shared memory allocation
functions use the NUMA node id advertised by the underlying device.

Intel Wired LAN Driver Updates 2024-05-28 (e1000e, i40e, ice) [part]

This series includes a variety of fixes that have been accumulating on the
Intel Wired LAN dev-queue.

Hui Wang provides a fix for suspend/resume on e1000e due to failure
to correctly setup the SMBUS in enable_ulp().

Thinh Tran provides a fix for EEH I/O suspend/resume on i40e to
ensure that I/O operations can continue after a resume. To avoid duplicate
code, the common logic is factored out of i40e_suspend and i40e_resume.

Paul Greenwalt provides a fix to correctly map the 200G PHY types to link
speeds in the ice driver.

Dave Ertman provides a fix correcting devlink parameter unregistration in
the event that the driver loads in safe mode and some of the parameters
were not registered.

On module load, the ice driver checks for the lack of a specific PF
capability to determine if it should reduce the number of devlink params
to register.  One situation when this test returns true is when the
driver loads in safe mode.  The same check is not present on the unload
path when devlink params are unregistered.  This results in the driver
triggering a WARN_ON in the kernel devlink code.

The current check and code path uses a reduction in the number of elements
reported in the list of params.  This is fragile and not good for future
maintaining.

Change the parameters to be held in two lists, one always registered and
one dependent on the check.

Add a symmetrical check in the unload path so that the correct parameters
are unregistered as well.

When EEH events occurs, the callback functions in the i40e, which are
managed by the EEH driver, will completely suspend and resume all IO
operations.

- In the PCI error detected callback, replaced i40e_prep_for_reset()
  with i40e_io_suspend(). The change is to fully suspend all I/O
  operations
- In the PCI error slot reset callback, replaced pci_enable_device_mem()

  the device.
- In the PCI error resume callback, replaced i40e_handle_reset_warning()

Two new functions, i40e_io_suspend() and i40e_io_resume(), have been
introduced.  These functions were factored out from the existing
i40e_suspend() and i40e_resume() respectively.  This factoring was
done due to concerns about the logic of the I40E_SUSPENSED state, which
caused the device to be unable to recover.  The functions are now used
in the EEH handling for device suspend/resume callbacks.

The function i40e_enable_mc_magic_wake() has been moved ahead of
i40e_io_suspend() to ensure it is declared before being used.

The commit 861e8086 ("e1000e: move force SMBUS from enable ulp
function to avoid PHY loss issue") introduces a regression on
PCH_MTP_I219_LM18 (PCIID: 0x8086550A). Without the referred commit, the
ethernet works well after suspend and resume, but after applying the
commit, the ethernet couldn't work anymore after the resume and the
dmesg shows that the NIC link changes to 10Mbps (1000Mbps originally):

    [   43.305084] e1000e 0000:00:1f.6 enp0s31f6: NIC Link is Up 10 Mbps Full Duplex, Flow Control: Rx/Tx

Without the commit, the force SMBUS code will not be executed if
"return 0" or "goto out" is executed in the enable_ulp(), and in my
case, the "goto out" is executed since FWSM_FW_VALID is set. But after
applying the commit, the force SMBUS code will be ran unconditionally.

Here move the force SMBUS code back to enable_ulp() and put it
immediately ahead of hw->phy.ops.release(hw), this could allow the
longest settling time as possible for interface in this function and
doesn't change the original code logic.

The issue was found on a Lenovo laptop with the ethernet hw as below:
00:1f.6 Ethernet controller [0200]: Intel Corporation Device [8086:550a]
(rev 20).

And this patch is verified (cable plug and unplug, system suspend

__dst_negative_advice() does not enforce proper RCU rules when
sk->dst_cache must be cleared, leading to possible UAF.

RCU rules are that we must first clear sk->sk_dst_cache,
then call dst_release(old_dst).

Note that sk_dst_reset(sk) is implementing this protocol correctly,
while __dst_negative_advice() uses the wrong order.

Given that ip6_negative_advice() has special logic
against RTF_CACHE, this means each of the three ->negative_advice()
existing methods must perform the sk_dst_reset() themselves.

Note the check against NULL dst is centralized in
__dst_negative_advice(), there is no need to duplicate
it in various callbacks.

Many thanks to Clement Lecigne for tracking this issue.

This reverts commit 681ce862.

We gave it a try, but it turns out the kernel test robot did in fact
find performance regressions for it, so we'll have to look at the more
involved alternative fixes for Yafang Shao's Elasticsearch load issue.

There were several alternatives discussed, they just weren't as simple
as this first attempt.

The report is of a -7.4% regression of filebench.sum_operations/s, which
appears significant enough to trigger my "this patch may get reverted if
somebody finds a performance regression on some other load" rule.

So it's still the case that we should end up deleting dentries more
aggressively - or just be better at pruning them later - but it needs a
bit more finesse than this simple thing.

Therefore, increasing the comparison between data length and count value to avoid

It is possible for syzbot to side-step the restriction imposed by the
blamed commit in the Fixes: tag, because the taprio UAPI permits a
cycle-time different from (and potentially shorter than) the sum of
entry intervals.

We need one more restriction, which is that the cycle time itself must
be larger than N * ETH_ZLEN bit times, where N is the number of schedule
entries. This restriction needs to apply regardless of whether the cycle
time came from the user or was the implicit, auto-calculated value, so
we move the existing "cycle == 0" check outside the "if "(!new->cycle_time)"
branch. This way covers both conditions and scenarios.

Add a selftest which illustrates the issue triggered by syzbot.

In commit b5b73b26 ("taprio: Fix allowing too small intervals"), a
comparison of user input against length_to_duration(q, ETH_ZLEN) was
introduced, to avoid RCU stalls due to frequent hrtimers.

The implementation of length_to_duration() depends on q->picos_per_byte
being set for the link speed. The blamed commit in the Fixes: tag has
moved this too late, so the checks introduced above are ineffective.
The q->picos_per_byte is zero at parse_taprio_schedule() ->
parse_sched_list() -> parse_sched_entry() -> fill_sched_entry() time.

Move the taprio_set_picos_per_byte() call as one of the first things in
taprio_change(), before the bulk of the netlink attribute parsing is
done. That's because it is needed there.

Add a selftest to make sure the issue doesn't get reintroduced.

Userspace assumes vlan header is present at a given offset, but vlan
offload allows to store this in metadata fields of the skbuff. Hence
mangling vlan results in a garbled packet. Handle this transparently by
adding a parser to the kernel.

If vlan metadata is present and payload offset is over 12 bytes (source
and destination mac address fields), then subtract vlan header present
in vlan metadata, otherwise mangle vlan metadata based on offset and
length, extracting data from the source register.

This is similar to:

  8cfd23e6 ("netfilter: nft_payload: work around vlan header stripping")

to deal with vlan payload mangling.
