If the cached contents of the CHCONF register doesn't have the FORCE bit
set, the setup() function failed to set the relevant idle state of the
SPI_CLK pin. In such case, the SPI_CLK's idle state is reached later with
set_cs(), but it's too late for the first SPI transfer which fails since
the CS is asserted before the clock reaching its idle state.
Add a first write in setup() that always sets the FORCE bit.
Keep the current write afterwards to ensure the FORCE bit won't stay in
the cached contents of the CHCONF register unless it's intended.

Enabling runtime PM allows the kernel to gate clocks and power to idle
devices. On SoCFPGA, a warm reset does not fully reinitialize these
domains.This leaves devices suspended and powered down, preventing U-Boot
or the kernel from reusing them after a warm reset, which breaks the boot
process.

Update the DMA Rust maintainers entry in the following two aspects:
(1) Change Abdiel's entry to 'Reviewer'.
(2) Take patches through the driver-core tree.
Abdiel won't do any more maintainer work on the DMA (or scatterlist)
infrastructure, but he'd like to be kept in the loop, hence change is
entry to 'R:'.
Analogous to [1], the DMA (and scatterlist) helpers are closely coupled
with the core device infrastructure and the device lifecycle, hence take
patches through the driver-core tree by default.

Currently, xattr name prefixes are forcibly placed into the packed
inode if the fragments feature is enabled, and users have no option
to put them in plain form directly on disk.
This is inflexible. First, as mentioned above, users should be able
to store unwrapped long xattr name prefixes unconditionally
(COMPAT_PLAIN_XATTR_PFX). Second, since we now have the new metabox
inode to store metadata, it should be used when available instead
of the packed inode.

hsr_port_get_hsr() iterates over ports using hsr_for_each_port(),
but many of its callers do not hold the required RCU lock.
Switch to hsr_for_each_port_rtnl(), since most callers already hold
the rtnl lock. After review, all callers are covered by either the rtnl
lock or the RCU lock, except hsr_dev_xmit(). Fix this by adding an
RCU read lock there.

hsr_for_each_port is called in many places without holding the RCU read
lock, this may trigger warnings on debug kernels. Most of the callers
are actually hold rtnl lock. So add a new helper hsr_for_each_port_rtnl
to allow callers in suitable contexts to iterate ports safely without
explicit RCU locking.
This patch only fixed the callers that is hold rtnl lock. Other caller

After commit 8cc71fc3b8 ("wifi: cfg80211: Fix "no buffer
space available" error in nl80211_get_station() for MLO"),
the per-link data is only included in station dumps, where
the size limit is somewhat less of an issue. However, it's
still an issue, depending on how many links a station has
and how much per-link data there is. Thus, for now, disable
per-link statistics entirely.
A complete fix will need to take this into account, make it
opt-in by userspace, and change the dump format to be able
to split a single station's data across multiple netlink
dump messages, which all together is too much development
for a fix.

Pull vmescape mitigation fixes from Dave Hansen:
"Mitigate vmscape issue with indirect branch predictor flushes.
vmscape is a vulnerability that essentially takes Spectre-v2 and
attacks host userspace from a guest. It particularly affects
hypervisors like QEMU.
Even if a hypervisor may not have any sensitive data like disk
encryption keys, guest-userspace may be able to attack the
guest-kernel using the hypervisor as a confused deputy.
There are many ways to mitigate vmscape using the existing Spectre-v2
defenses like IBRS variants or the IBPB flushes. This series focuses
solely on IBPB because it works universally across vendors and all
vulnerable processors. Further work doing vendor and model-specific
optimizations can build on top of this if needed / wanted.
Do the normal issue mitigation dance:
- Add the CPU bug boilerplate
- Add a list of vulnerable CPUs
- Use IBPB to flush the branch predictors after running guests"

Merge tag 'nf-25-09-10-v2' of https://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf
Florian Westpha says:
====================
netfilter pull request nf-25-09-10
First patch adds a lockdep annotation for a false-positive splat.
Last patch adds formal reviewer tag for Phil Sutter to MAINTAINERS.
Rest of the patches resolve spurious false negative results during set
lookups while another CPU is processing a transaction.
This has been broken at least since v4.18 when an unconditional
synchronize_rcu call was removed from the commit phase of nf_tables.
Quoting from Stefan Hanreichs original report:
It seems like we've found an issue with atomicity when reloading
nftables rulesets. Sometimes there is a small window where rules
containing sets do not seem to apply to incoming traffic, due to the set
apparently being empty for a short amount of time when flushing / adding
elements.
Exanple ruleset:
table ip filter {
set match {
type ipv4_addr
flags interval
elements = { 0.0.0.0-192.168.2.19, 192.168.2.21-255.255.255.255 }
}
chain pre {
type filter hook prerouting priority filter; policy accept;
ip saddr @match accept
counter comment "must never match"
}
}
Reproducer transaction:
while true:
nft -f -<<EOF
flush set ip filter match
create element ip filter match { \
0.0.0.0-192.168.2.19, 192.168.2.21-255.255.255.255 }
EOF
done
Then create traffic. to/from e.g. 192.168.2.1 to 192.168.3.10.
Once in a while the counter will increment even though the
'ip saddr @match' rule should have accepted the packet.
See individual patches for details.
Thanks to Stefan Hanreich for an initial description and reproducer for
this bug and to Pablo Neira Ayuso for reviewing earlier iterations of
the patchset.

Drop phylink_{suspend,resume}() from ax88772 PM callbacks.
MDIO bus accesses have their own runtime-PM handling and will try to
wake the device if it is suspended. Such wake attempts must not happen
from PM callbacks while the device PM lock is held. Since phylink
{sus|re}sume may trigger MDIO, it must not be called in PM context.
No extra phylink PM handling is required for this driver:
- .ndo_open/.ndo_stop control the phylink start/stop lifecycle.
- ethtool/phylib entry points run in process context, not PM.
- phylink MAC ops program the MAC on link changes after resume.

In C, enumerated types do not have a defined size, apart from being
compatible with one of the standard types. This allows an ABI /
compiler to choose the type of an enum depending on the values it
needs to store, and storing larger values in it can lead to undefined
behaviour.
The tx_type and rx_filters members of struct kernel_ethtool_ts_info
are defined as enumerated types, but are bit arrays, where each bit
is defined by the enumerated type. This means they typically store
values in excess of the maximum value of the enumerated type, in
fact (1 << max_value) and thus must not be declared using the
enumated type.
Fix both of these to use u32, as per the corresponding __u32 UAPI type.
