Pull gpio fixes from Bartosz Golaszewski:
"Some last-minute fixes for this release from the GPIO subsystem.
The first two address a regression in performance reported to me after
the conversion to using SRCU in GPIOLIB that was merged during the
v6.9 merge window. The second patch is not technically a fix but since
after the first one we no longer need to use a per-descriptor SRCU
struct, I think it's worth to simplify the code before it gets
released on Sunday.
The next two commits fix two memory issues: one use-after-free bug and
one instance of possibly leaking kernel stack memory to user-space.
Summary:
- fix a performance regression in GPIO requesting and releasing after
the conversion to SRCU
- fix a use-after-free bug due to a race-condition
- fix leaking stack memory to user-space in a GPIO uABI corner case"

In commit 0518dbe97fe6 ("selftests/mm: fix cross compilation with LLVM")
the logic to detect the machine architecture in the Makefile was changed
to use ARCH, and only fallback to uname -m if ARCH is unset. However the
tests of ARCH were not updated to account for the fact that ARCH is
"powerpc" for powerpc builds, not "ppc64".
Fix it by changing the checks to look for "powerpc", and change the
uname -m logic to convert "ppc64.*" into "powerpc".
With that fixed the following tests now build for powerpc again:
* protection_keys
* va_high_addr_switch
* virtual_address_range
* write_to_hugetlbfs

We don't get the right offset in that case. The GPU has
an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.

The original topology evaluation code initialized cpu_data::topo::llc_id
with the die ID initialy and then eventually overwrite it with information
gathered from a CPUID leaf.
The conversion analysis failed to spot that particular detail and omitted
this initial assignment under the assumption that each topology evaluation
path will set it up. That assumption is mostly correct, but turns out to be
wrong in case that the CPUID leaf 0x80000006 does not provide a LLC ID.
In that case, LLC ID is invalid and as a consequence the setup of the
scheduling domain CPU masks is incorrect which subsequently causes the
scheduler core to complain about it during CPU hotplug:
BUG: arch topology borken
the CLS domain not a subset of the MC domain
Cure it by reusing legacy_set_llc() and assigning the die ID if the LLC ID
is invalid after all possible parsers have been tried.

If a line is requested with debounce, and that results in debouncing
in software, and the line is subsequently reconfigured to enable edge
detection then the allocation of the kfifo to contain edge events is
overlooked. This results in events being written to and read from an
uninitialised kfifo. Read events are returned to userspace.
Initialise the kfifo in the case where the software debounce is
already active.

====================
gtp pull request 24-05-07
This v3 includes:
- fix for clang uninitialized variable per Jakub.
- address Smatch and Coccinelle reports per Simon
- remove inline in new IPv6 support per Simon
- fix memleaks in netlink control plane per Simon
-o-
The following patchset contains IPv6 GTP driver support for net-next,
this also includes IPv6 over IPv4 and vice-versa:
Patch #1 removes a unnecessary stack variable initialization in the
socket routine.
Patch #2 deals with GTP extension headers. This variable length extension
header to decapsulate packets accordingly. Otherwise, packets are
dropped when these extension headers are present which breaks
interoperation with other non-Linux based GTP implementations.
Patch #3 prepares for IPv6 support by moving IPv4 specific fields in PDP
context objects to a union.
Patch #4 adds IPv6 support while retaining backward compatibility.
Three new attributes allows to declare an IPv6 GTP tunnel
GTPA_FAMILY, GTPA_PEER_ADDR6 and GTPA_MS_ADDR6 as well as
IFLA_GTP_LOCAL6 to declare the IPv6 GTP UDP socket. Up to this
patch, only IPv6 outer in IPv6 inner is supported.
Patch #5 uses IPv6 address /64 prefix for UE/MS in the inner headers.
Unlike IPv4, which provides a 1:1 mapping between UE/MS,
IPv6 tunnel encapsulates traffic for /64 address as specified
by 3GPP TS. Patch has been split from Patch #4 to highlight
this behaviour.
Patch #6 passes up IPv6 link-local traffic, such as IPv6 SLAAC, for
handling to userspace so they are handled as control packets.
Patch #7 prepares to allow for GTP IPv4 over IPv6 and vice-versa by
moving IP specific debugging out of the function to build
IPv4 and IPv6 GTP packets.
Patch #8 generalizes TOS/DSCP handling following similar approach as
in the existing iptunnel infrastructure.
Patch #9 adds a helper function to build an IPv4 GTP packet in the outer
header.
Patch #10 adds a helper function to build an IPv6 GTP packet in the outer
header.
Patch #11 adds support for GTP IPv4-over-IPv6 and vice-versa.
Patch #12 allows to use the same TID/TEID (tunnel identifier) for inner
IPv4 and IPv6 packets for better UE/MS dual stack integration.
This series integrates with the osmocom.org project CI and TTCN-3 test
infrastructure (Oliver Smith) as well as the userspace libgtpnl library.
Thanks to Harald Welte, Oliver Smith and Pau Espin for reviewing and
providing feedback through the osmocom.org redmine platform to make this
happen.

The NOP op flags should have been checked from beginning like any other
opcode, otherwise NOP may not be extended with the op flags.
Given both liburing and Rust io-uring crate always zeros SQE op flags, just
ignore users which play raw NOP uring interface without zeroing SQE, because
NOP is just for test purpose. Then we can save one NOP2 opcode.

Sven Auhagen reports transaction failures with following error:
./main.nft:13:1-26: Error: Could not process rule: Cannot allocate memory
percpu: allocation failed, size=16 align=8 atomic=1, atomic alloc failed, no space left
This points to failing pcpu allocation with GFP_ATOMIC flag.
However, transactions happen from user context and are allowed to sleep.
One case where we can call into percpu allocator with GFP_ATOMIC is
nft_counter expression.
Normally this happens from control plane, so this could use GFP_KERNEL
instead. But one use case, element insertion from packet path,
needs to use GFP_ATOMIC allocations (nft_dynset expression).
At this time, .clone callbacks always use GFP_ATOMIC for this reason.
Add gfp_t argument to the .clone function and pass GFP_KERNEL or
GFP_ATOMIC flag depending on context, this allows all clone memory
allocations to sleep for the normal (transaction) case.

Add a new test script that uses packetdrill tool to exercise conntrack
state machine.
Needs ip/ip6tables and conntrack tool (to check if we have an entry in
the expected state).
Test cases added here cover following scenarios:
1. already-acked (retransmitted) packets are not tagged as INVALID
2. RST packet coming when conntrack is already closing (FIN/CLOSE_WAIT)
transitions conntrack to CLOSE even if the RST is not an exact match
3. RST packets with out-of-window sequence numbers are marked as INVALID
4. SYN+Challenge ACK: check that challenge ack is allowed to pass
5. Old SYN/ACK: check conntrack handles the case where SYN is answered
with SYN/ACK for an old, previous connection attempt
6. Check SYN reception while in ESTABLISHED state generates a challenge
ack, RST response clears 'outdated' state + next SYN retransmit gets
us into 'SYN_RECV' conntrack state.
Tests get run twice, once with ipv4 and once with ipv6.

This set type keeps two copies of the sets' content,
priv->match (live version, used to match from packet path)
priv->clone (work-in-progress version of the 'future' priv->match).
All additions and removals are done on priv->clone. When transaction
completes, priv->clone becomes priv->match and a new clone is allocated
for use by next transaction.
Problem is that the cloning requires GFP_KERNEL allocations but we
cannot fail at either commit or abort time.
This patch defers the clone until we get an insertion or removal
request. This allows us to handle OOM situations correctly.
This also allows to remove ->dirty in a followup change:
If ->clone exists, ->dirty is always true
If ->clone is NULL, ->dirty is always false, no elements were added
or removed (except catchall elements which are external to the specific

The helper uses priv->clone unconditionally which will fail once we do
the clone conditionally on first insert or removal.
'nft get element' from userspace needs to use priv->match since this
runs from rcu read side lock section.
Prepare for this by passing the match backend data as argument.

In IPv6, ipv6_rcv_core will parse the hop-by-hop type extension header and increase skb->transport_header by one extension header length.
But if there are more other extension headers like fragment header at this time, the skb->transport_header points to the second extension header,
not the transport layer header or the first extension header.
This will result in the start and nexthdrp variable not pointing to the same position in ipv6frag_thdr_trunced,
and ipv6_skip_exthdr returning incorrect offset and frag_off.Sometimes,the length of the last sharded packet is smaller than the calculated incorrect offset, resulting in packet loss.
We can use network header to offset and calculate the correct position to solve this problem.

The Renesas OS Timer (OSTM) driver contains two probe points, of which
only one should complete:
1. Early probe, using TIMER_OF_DECLARE(), to provide the sole
clocksource on (arm32) RZ/A1 and RZ/A2 SoCs,
2. Normal probe, using a platform driver, to provide additional timers
on (arm64 + riscv) RZ/G2L and similar SoCs.
The latter is needed because using OSTM on RZ/G2L requires manipulation
of its reset signal, which is not yet available at the time of early
probe, causing early probe to fail with -EPROBE_DEFER. It is only
enabled when building a kernel with support for the RZ/G2L family, so it
does not impact RZ/A1 and RZ/A2. Hence only one probe method can
complete on all affected systems.
As relying on the order of initialization of subsystems inside the
kernel is fragile, set the DT node's OF_POPULATED flag after a succesful
early probe. This makes sure the platform driver's probe is never
called after a successful early probe.

The RZ/V2H(P) (R9A09G057) SoC is equipped with the Generic Timer Module,
also known as OSTM. Similar to the RZ/G2L SoC, the OSTM on the RZ/V2H(P)
SoC requires the reset line to be deasserted before accessing any
registers.
Early call to ostm_init() happens through TIMER_OF_DECLARE() which always
fails with -EPROBE_DEFER, as resets are not available that early in the
boot process. To address this issue on the RZ/V2H(P) SoC, enable the OSTM
driver to be reprobed through the platform driver probe mechanism.

This was missed because of the function pointer indirection.
nvidia_smmu_context_fault() is also installed as a irq function, and the
'void *' was changed to a struct arm_smmu_domain. Since the iommu_domain
is embedded at a non-zero offset this causes nvidia_smmu_context_fault()
to miscompute the offset. Fixup the types.

Fix the fileserver rotation code in a couple of ways:
(1) op->server_states is an array, not a pointer to a single record, so
fix the places that access it to index it.
(2) In the places that go through an address list to work out which one
has the best priority, fix the loops to skip known failed addresses.
Without this, the rotation algorithm may get stuck on addresses that are
inaccessible or don't respond.
This can be triggered manually by finding a server that advertises a
non-routable address and giving it a higher priority, eg.:
echo "add udp 192.168.0.0/16 3000" >/proc/fs/afs/addr_prefs
if the server, say, includes the address 192.168.7.7 in its address list,
and then attempting to access a volume on that server.
