net: devmem: ksft: add exit_wait to make rx test pass
This exit_wait seems necessary to make the rx side test pass for me. I think this is just missed from the original test add patch. Add it now.

net: devmem: ksft: add ipv4 support
ncdevmem supports both ipv4 and ipv6, but the ksft is currently ipv6-only. Propagate the ipv4 support to the ksft, so that folks that are limited to these networks can also test.

selftests: netfilter: nft_queue.sh: include file transfer duration in log message
Paolo Abeni says: Recently the nipa CI infra went through some tuning, and the mentioned self-test now often fails. The failing test is the sctp+nfqueue one, where the file transfer takes too long and hits the timeout (1 minute). Because SCTP nfqueue tests had timeout related issues before (esp. on debug kernels) print the file transfer duration in the PASS/FAIL message. This would aallow us to see if there is/was an unexpected slowdown (CI keeps logs around) or 'creeping slowdown' where things got slower over time until 'fail point' was reached. Output of altered lines looks like this: PASS: tcp and nfqueue in forward chan (duration: 2s) PASS: tcp via loopback (duration: 2s) PASS: sctp and nfqueue in forward chain (duration: 42s) PASS: sctp and nfqueue in output chain with GSO (duration: 21s) Reported-by: Paolo Abeni <pabeni@redhat.com Closes: https://lore.kernel.org/netdev/584524ef-9fd7-4326-9f1b-693ca62c5692@redhat.com/ Signed-off-by: Florian Westphal <fw@strlen.de> Link: https://patch.msgid.link/20250523121700.20011-1-fw@strlen.de Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

selftests: net: move wait_local_port_listen to lib.sh
The function wait_local_port_listen() is the only function defined in net_helper.sh. Since some tests source both lib.sh and net_helper.sh, we can simplify the setup by moving wait_local_port_listen() to lib.sh. With this change, net_helper.sh becomes redundant and can be removed.

gpio updates for v6.16-rc1
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where applicable
which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which will
take off the burden from GPIO drivers of checking this down the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter callbacks
- convert more drivers to making the irq_chip immutable as is recommended
by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built with
COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that makes
the setup easier for user-space than the existing driver-level sysfs
attributes and also adds more advanced configuration features (such as
referring to aggregated lines by their original names or modifying
their names as exposed by the aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the global
GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new
drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents
Misc:
- TODO list updates

Pull gpio updates from Bartosz Golaszewski:
"We have three new drivers, some refactoring in the GPIO core, lots of
various changes across many drivers, new configfs interface for the
virtual gpio-aggregator module and DT-bindings updates.
The treewide conversion of GPIO drivers to using the new value setter
callbacks is ongoing with another round of GPIO drivers updated. You
will also see these commits coming in from other subsystems as with
the relevant changes merged into mainline last cycle, I've started
converting GPIO providers located elsewhere than drivers/gpio/.

selftests/bpf: Add tests with stack ptr register in conditional jmp
Add two tests:
- one test has 'rX <op> r10' where rX is not r10, and
- another test has 'rX <op> rY' where rX and rY are not r10
but there is an early insn 'rX = r10'.
Without previous verifier change, both tests will fail.

wireguard: allowedips: add WGALLOWEDIP_F_REMOVE_ME flag
The current netlink API for WireGuard does not directly support removal of allowed ips from a peer. A user can remove an allowed ip from a peer in one of two ways: 1. By using the WGPEER_F_REPLACE_ALLOWEDIPS flag and providing a new list of allowed ips which omits the allowed ip that is to be removed. 2. By reassigning an allowed ip to a "dummy" peer then removing that peer with WGPEER_F_REMOVE_ME. With the first approach, the driver completely rebuilds the allowed ip list for a peer. If my current configuration is such that a peer has allowed ips 192.168.0.2 and 192.168.0.3 and I want to remove 192.168.0.2 the actual transition looks like this. [192.168.0.2, 192.168.0.3] <-- Initial state [] <-- Step 1: Allowed ips removed for peer [192.168.0.3] <-- Step 2: Allowed ips added back for peer This is true even if the allowed ip list is small and the update does not need to be batched into multiple WG_CMD_SET_DEVICE requests, as the removal and subsequent addition of ips is non-atomic within a single request. Consequently, wg_allowedips_lookup_dst and wg_allowedips_lookup_src may return NULL while reconfiguring a peer even for packets bound for ips a user did not intend to remove leading to unintended interruptions in connectivity. This presents in userspace as failed calls to sendto and sendmsg for UDP sockets. In my case, I ran netperf while repeatedly reconfiguring the allowed ips for a peer with wg. /usr/local/bin/netperf -H 10.102.73.72 -l 10m -t UDP_STREAM -- -R 1 -m 1024 send_data: data send error: No route to host (errno 113) netperf: send_omni: send_data failed: No route to host While this may not be of particular concern for environments where peers and allowed ips are mostly static, systems like Cilium manage peers and allowed ips in a dynamic environment where peers (i.e. Kubernetes nodes) and allowed ips (i.e. pods running on those nodes) can frequently change making WGPEER_F_REPLACE_ALLOWEDIPS problematic. The second approach avoids any possible connectivity interruptions but is hacky and less direct, requiring the creation of a temporary peer just to dispose of an allowed ip. Introduce a new flag called WGALLOWEDIP_F_REMOVE_ME which in the same way that WGPEER_F_REMOVE_ME allows a user to remove a single peer from a WireGuard device's configuration allows a user to remove an ip from a peer's set of allowed ips. This enables incremental updates to a device's configuration without any connectivity blips or messy workarounds. A corresponding patch for wg extends the existing `wg set` interface to leverage this feature. $ wg set wg0 peer <PUBKEY> allowed-ips +192.168.88.0/24,-192.168.0.1/32 When '+' or '-' is prepended to any ip in the list, wg clears WGPEER_F_REPLACE_ALLOWEDIPS and sets the WGALLOWEDIP_F_REMOVE_ME flag on any ip prefixed with '-'.

KVM/arm64 updates for 6.16
* New features:
- Add large stage-2 mapping support for non-protected pKVM guests,
clawing back some performance.
- Add UBSAN support to the standalone EL2 object used in nVHE/hVHE and
protected modes.
- Enable nested virtualisation support on systems that support it
(yes, it has been a long time coming), though it is disabled by
default.
* Improvements, fixes and cleanups:
- Large rework of the way KVM tracks architecture features and links
them with the effects of control bits. This ensures correctness of
emulation (the data is automatically extracted from the published
JSON files), and helps dealing with the evolution of the
architecture.
- Significant changes to the way pKVM tracks ownership of pages,
avoiding page table walks by storing the state in the hypervisor's
vmemmap. This in turn enables the THP support described above.
- New selftest checking the pKVM ownership transition rules
- Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
even if the host didn't have it.
- Fixes for the address translation emulation, which happened to be
rather buggy in some specific contexts.
- Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
from the number of counters exposed to a guest and addressing a
number of issues in the process.
- Add a new selftest for the SVE host state being corrupted by a
guest.
- Keep HCR_EL2.xMO set at all times for systems running with the
kernel at EL2, ensuring that the window for interrupts is slightly
bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
- Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
from a pretty bad case of TLB corruption unless accesses to HCR_EL2
are heavily synchronised.
- Add a per-VM, per-ITS debugfs entry to dump the state of the ITS
tables in a human-friendly fashion.
- and the usual random cleanups.

Merge tag 'vfs-6.16-rc1.coredump' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull coredump updates from Christian Brauner:
"This adds support for sending coredumps over an AF_UNIX socket. It
also makes (implicit) use of the new SO_PEERPIDFD ability to hand out
pidfds for reaped peer tasks
The new coredump socket will allow userspace to not have to rely on
usermode helpers for processing coredumps and provides a saf way to
handle them instead of relying on super privileged coredumping helpers
This will also be significantly more lightweight since the kernel
doens't have to do a fork()+exec() for each crashing process to spawn
a usermodehelper. Instead the kernel just connects to the AF_UNIX
socket and userspace can process it concurrently however it sees fit.
Support for userspace is incoming starting with systemd-coredump
There's more work coming in that direction next cycle. The rest below
goes into some details and background
Coredumping currently supports two modes:
(1) Dumping directly into a file somewhere on the filesystem.
(2) Dumping into a pipe connected to a usermode helper process
spawned as a child of the system_unbound_wq or kthreadd
For simplicity I'm mostly ignoring (1). There's probably still some
users of (1) out there but processing coredumps in this way can be
considered adventurous especially in the face of set*id binaries
The most common option should be (2) by now. It works by allowing
userspace to put a string into /proc/sys/kernel/core_pattern like:
|/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h
The "|" at the beginning indicates to the kernel that a pipe must be
used. The path following the pipe indicator is a path to a binary that
will be spawned as a usermode helper process. Any additional
parameters pass information about the task that is generating the
coredump to the binary that processes the coredump
In the example the core_pattern shown causes the kernel to spawn
systemd-coredump as a usermode helper. There's various conceptual
consequences of this (non-exhaustive list):
- systemd-coredump is spawned with file descriptor number 0 (stdin)
connected to the read-end of the pipe. All other file descriptors
are closed. That specifically includes 1 (stdout) and 2 (stderr).
This has already caused bugs because userspace assumed that this
cannot happen (Whether or not this is a sane assumption is
irrelevant)
- systemd-coredump will be spawned as a child of system_unbound_wq.
So it is not a child of any userspace process and specifically not
a child of PID 1. It cannot be waited upon and is in a weird hybrid
upcall which are difficult for userspace to control correctly
- systemd-coredump is spawned with full kernel privileges. This
necessitates all kinds of weird privilege dropping excercises in
userspace to make this safe
- A new usermode helper has to be spawned for each crashing process
This adds a new mode:
(3) Dumping into an AF_UNIX socket
Userspace can set /proc/sys/kernel/core_pattern to:
@/path/to/coredump.socket
The "@" at the beginning indicates to the kernel that an AF_UNIX
coredump socket will be used to process coredumps
The coredump socket must be located in the initial mount namespace.
When a task coredumps it opens a client socket in the initial network
namespace and connects to the coredump socket:
- The coredump server uses SO_PEERPIDFD to get a stable handle on the
connected crashing task. The retrieved pidfd will provide a stable
reference even if the crashing task gets SIGKILLed while generating
the coredump. That is a huge attack vector right now
- By setting core_pipe_limit non-zero userspace can guarantee that
the crashing task cannot be reaped behind it's back and thus
process all necessary information in /proc/<pid>. The SO_PEERPIDFD
can be used to detect whether /proc/<pid> still refers to the same
process
The core_pipe_limit isn't used to rate-limit connections to the
socket. This can simply be done via AF_UNIX socket directly
- The pidfd for the crashing task will contain information how the
task coredumps. The PIDFD_GET_INFO ioctl gained a new flag
PIDFD_INFO_COREDUMP which can be used to retreive the coredump
information
If the coredump gets a new coredump client connection the kernel
guarantees that PIDFD_INFO_COREDUMP information is available.
Currently the following information is provided in the new
@coredump_mask extension to struct pidfd_info:
* PIDFD_COREDUMPED is raised if the task did actually coredump
* PIDFD_COREDUMP_SKIP is raised if the task skipped coredumping
(e.g., undumpable)
* PIDFD_COREDUMP_USER is raised if this is a regular coredump and
doesn't need special care by the coredump server
* PIDFD_COREDUMP_ROOT is raised if the generated coredump should
be treated as sensitive and the coredump server should restrict
access to the generated coredump to sufficiently privileged
users"
* tag 'vfs-6.16-rc1.coredump' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
mips, net: ensure that SOCK_COREDUMP is defined

Pull pidfs updates from Christian Brauner:
"Features:
- Allow handing out pidfds for reaped tasks for AF_UNIX SO_PEERPIDFD
socket option
SO_PEERPIDFD is a socket option that allows to retrieve a pidfd for
the process that called connect() or listen(). This is heavily used
to safely authenticate clients in userspace avoiding security bugs
due to pid recycling races (dbus, polkit, systemd, etc.)
SO_PEERPIDFD currently doesn't support handing out pidfds if the
sk->sk_peer_pid thread-group leader has already been reaped. In
this case it currently returns EINVAL. Userspace still wants to get
a pidfd for a reaped process to have a stable handle it can pass
on. This is especially useful now that it is possible to retrieve
exit information through a pidfd via the PIDFD_GET_INFO ioctl()'s
PIDFD_INFO_EXIT flag
Another summary has been provided by David Rheinsberg:
> A pidfd can outlive the task it refers to, and thus user-space
> must already be prepared that the task underlying a pidfd is
> gone at the time they get their hands on the pidfd. For
> instance, resolving the pidfd to a PID via the fdinfo must be
> prepared to read `-1`.
>
> Despite user-space knowing that a pidfd might be stale, several
> kernel APIs currently add another layer that checks for this. In
> particular, SO_PEERPIDFD returns `EINVAL` if the peer-task was
> already reaped, but returns a stale pidfd if the task is reaped
> immediately after the respective alive-check.
>
> This has the unfortunate effect that user-space now has two ways
> to check for the exact same scenario: A syscall might return
> EINVAL/ESRCH/... *or* the pidfd might be stale, even though
> there is no particular reason to distinguish both cases. This
> also propagates through user-space APIs, which pass on pidfds.
> They must be prepared to pass on `-1` *or* the pidfd, because
> there is no guaranteed way to get a stale pidfd from the kernel.
>
> Userspace must already deal with a pidfd referring to a reaped
> task as the task may exit and get reaped at any time will there
> are still many pidfds referring to it
In order to allow handing out reaped pidfd SO_PEERPIDFD needs to
ensure that PIDFD_INFO_EXIT information is available whenever a
pidfd for a reaped task is created by PIDFD_INFO_EXIT. The uapi
promises that reaped pidfds are only handed out if it is guaranteed
that the caller sees the exit information:
TEST_F(pidfd_info, success_reaped)
{
struct pidfd_info info = {
.mask = PIDFD_INFO_CGROUPID | PIDFD_INFO_EXIT,
};
/*
* Process has already been reaped and PIDFD_INFO_EXIT been set.
* Verify that we can retrieve the exit status of the process.
*/
ASSERT_EQ(ioctl(self->child_pidfd4, PIDFD_GET_INFO, &info), 0);
ASSERT_FALSE(!!(info.mask & PIDFD_INFO_CREDS));
ASSERT_TRUE(!!(info.mask & PIDFD_INFO_EXIT));
ASSERT_TRUE(WIFEXITED(info.exit_code));
ASSERT_EQ(WEXITSTATUS(info.exit_code), 0);
}
To hand out pidfds for reaped processes we thus allocate a pidfs
entry for the relevant sk->sk_peer_pid at the time the
sk->sk_peer_pid is stashed and drop it when the socket is
destroyed. This guarantees that exit information will always be
recorded for the sk->sk_peer_pid task and we can hand out pidfds
for reaped processes
- Hand a pidfd to the coredump usermode helper process
Give userspace a way to instruct the kernel to install a pidfd for
the crashing process into the process started as a usermode helper.
There's still tricky race-windows that cannot be easily or
sometimes not closed at all by userspace. There's various ways like
looking at the start time of a process to make sure that the
usermode helper process is started after the crashing process but
it's all very very brittle and fraught with peril
The crashed-but-not-reaped process can be killed by userspace
before coredump processing programs like systemd-coredump have had
time to manually open a PIDFD from the PID the kernel provides
them, which means they can be tricked into reading from an
arbitrary process, and they run with full privileges as they are
usermode helper processes
Even if that specific race-window wouldn't exist it's still the
safest and cleanest way to let the kernel provide the pidfd
directly instead of requiring userspace to do it manually. In
parallel with this commit we already have systemd adding support
for this in [1]
When the usermode helper process is forked we install a pidfd file
descriptor three into the usermode helper's file descriptor table
so it's available to the exec'd program
Since usermode helpers are either children of the system_unbound_wq
workqueue or kthreadd we know that the file descriptor table is
empty and can thus always use three as the file descriptor number
Note, that we'll install a pidfd for the thread-group leader even
if a subthread is calling do_coredump(). We know that task linkage
hasn't been removed yet and even if this @current isn't the actual
thread-group leader we know that the thread-group leader cannot be
reaped until
@current has exited
- Allow telling when a task has not been found from finding the wrong
task when creating a pidfd
We currently report EINVAL whenever a struct pid has no tasked
attached anymore thereby conflating two concepts:
(1) The task has already been reaped
(2) The caller requested a pidfd for a thread-group leader but the
pid actually references a struct pid that isn't used as a
thread-group leader
This is causing issues for non-threaded workloads as in where they
expect ESRCH to be reported, not EINVAL
So allow userspace to reliably distinguish between (1) and (2)
- Make it possible to detect when a pidfs entry would outlive the
struct pid it pinned
- Add a range of new selftests
Cleanups:
- Remove unneeded NULL check from pidfd_prepare() for passed struct
pid
- Avoid pointless reference count bump during release_task()
Fixes:
- Various fixes to the pidfd and coredump selftests
- Fix error handling for replace_fd() when spawning coredump usermode
helper"

Pull misc vfs updates from Christian Brauner:
"This contains the usual selections of misc updates for this cycle.
Features:
- Use folios for symlinks in the page cache
FUSE already uses folios for its symlinks. Mirror that conversion
in the generic code and the NFS code. That lets us get rid of a few
folio->page->folio conversions in this path, and some of the few
remaining users of read_cache_page() / read_mapping_page()
- Try and make a few filesystem operations killable on the VFS
inode->i_mutex level
- Add sysctl vfs_cache_pressure_denom for bulk file operations
Some workloads need to preserve more dentries than we currently
allow through out sysctl interface
A HDFS servers with 12 HDDs per server, on a HDFS datanode startup
involves scanning all files and caching their metadata (including
dentries and inodes) in memory. Each HDD contains approximately 2
million files, resulting in a total of ~20 million cached dentries
after initialization
To minimize dentry reclamation, they set vfs_cache_pressure to 1.
Despite this configuration, memory pressure conditions can still
trigger reclamation of up to 50% of cached dentries, reducing the
cache from 20 million to approximately 10 million entries. During
the subsequent cache rebuild period, any HDFS datanode restart
operation incurs substantial latency penalties until full cache
recovery completes
To maintain service stability, more dentries need to be preserved
during memory reclamation. The current minimum reclaim ratio (1/100
of total dentries) remains too aggressive for such workload. This
patch introduces vfs_cache_pressure_denom for more granular cache
pressure control
The configuration [vfs_cache_pressure=1,
vfs_cache_pressure_denom=10000] effectively maintains the full 20
million dentry cache under memory pressure, preventing datanode
restart performance degradation
- Avoid some jumps in inode_permission() using likely()/unlikely()
- Avid a memory access which is most likely a cache miss when
descending into devcgroup_inode_permission()
- Add fastpath predicts for stat() and fdput()
- Anonymous inodes currently don't come with a proper mode causing
issues in the kernel when we want to add useful VFS debug assert.
Fix that by giving them a proper mode and masking it off when we
report it to userspace which relies on them not having any mode
- Anonymous inodes currently allow to change inode attributes because
the VFS falls back to simple_setattr() if i_op->setattr isn't
implemented. This means the ownership and mode for every single
user of anon_inode_inode can be changed. Block that as it's either
useless or actively harmful. If specific ownership is needed the
respective subsystem should allocate anonymous inodes from their
own private superblock
- Raise SB_I_NODEV and SB_I_NOEXEC on the anonymous inode superblock
- Add proper tests for anonymous inode behavior
- Make it easy to detect proper anonymous inodes and to ensure that
we can detect them in codepaths such as readahead()
Cleanups:
- Port pidfs to the new anon_inode_{g,s}etattr() helpers
- Try to remove the uselib() system call
- Add unlikely branch hint return path for poll
- Add unlikely branch hint on return path for core_sys_select
- Don't allow signals to interrupt getdents copying for fuse
- Provide a size hint to dir_context for during readdir()
- Use writeback_iter directly in mpage_writepages
- Update compression and mtime descriptions in initramfs
documentation
- Update main netfs API document
- Remove useless plus one in super_cache_scan()
- Remove unnecessary NULL-check guards during setns()
- Add separate separate {get,put}_cgroup_ns no-op cases
Fixes:
- Fix typo in root= kernel parameter description
- Use KERN_INFO for infof()|info_plog()|infofc()
- Correct comments of fs_validate_description()
- Mark an unlikely if condition with unlikely() in
vfs_parse_monolithic_sep()
- Delete macro fsparam_u32hex()
- Remove unused and problematic validate_constant_table()
- Fix potential unsigned integer underflow in fs_name()
- Make file-nr output the total allocated file handles"

cxl/edac: Add CXL memory device patrol scrub control feature
CXL spec 3.2 section 8.2.10.9.11.1 describes the device patrol scrub control feature. The device patrol scrub proactively locates and makes corrections to errors in regular cycle. Allow specifying the number of hours within which the patrol scrub must be completed, subject to minimum and maximum limits reported by the device. Also allow disabling scrub allowing trade-off error rates against performance. Add support for patrol scrub control on CXL memory devices. Register with the EDAC device driver, which retrieves the scrub attribute descriptors from EDAC scrub and exposes the sysfs scrub control attributes to userspace. For example, scrub control for the CXL memory device "cxl_mem0" is exposed in /sys/bus/edac/devices/cxl_mem0/scrubX/. Additionally, add support for region-based CXL memory patrol scrub control. CXL memory regions may be interleaved across one or more CXL memory devices. For example, region-based scrub control for "cxl_region1" is exposed in /sys/bus/edac/devices/cxl_region1/scrubX/.

While doing so: - Keep an 'nft monitor' running in background to receive the notifications - Loop over 'nft list ruleset' to exercise ruleset dump codepath - Have iperf running so the involved chains/flowtables see traffic If supported, also test interface wildcard support separately by creating a flowtable with 'wild*' interface spec and quickly add/remove matching dummy interfaces.

selftests: netfilter: nft_fib.sh: add type and oif tests with and without VRFs
Replace the existing VRF test with a more comprehensive one. It tests following combinations: - fib type (returns address type, e.g. unicast) - fib oif (route output interface index - both with and without 'iif' keyword (changes result, e.g. 'fib daddr type local' will be true when the destination address is configured on the local machine, but 'fib daddr . iif type local' will only be true when the destination address is configured on the incoming interface. Add all types of addresses to test with for both ipv4 and ipv6: - local address on the incoming interface - local address on another interface - local address on another interface thats part of a vrf - address on another host The ruleset stores obtained results from 'fib' in nftables sets and then queries the sets to check that it has the expected results. Perform one pass while packets are coming in on interface NOT part of a VRF and then again when it was added and make sure fib returns the expected routes and address types for the various addresses in the setup.

Merge branch kvm-arm64/misc-6.16 into kvmarm-master/next
* kvm-arm64/misc-6.16: : . : Misc changes and improvements for 6.16: : : - Add a new selftest for the SVE host state being corrupted by a guest : : - Keep HCR_EL2.xMO set at all times for systems running with the kernel at EL2, : ensuring that the window for interrupts is slightly bigger, and avoiding : a pretty bad erratum on the AmpereOne HW : : - Replace a couple of open-coded on/off strings with str_on_off() : : - Get rid of the pKVM memblock sorting, which now appears to be superflous : : - Drop superflous clearing of ICH_LR_EOI in the LR when nesting : : - Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers from : a pretty bad case of TLB corruption unless accesses to HCR_EL2 are : heavily synchronised : : - Add a per-VM, per-ITS debugfs entry to dump the state of the ITS tables : in a human-friendly fashion : . KVM: arm64: Fix documentation for vgic_its_iter_next() KVM: arm64: vgic-its: Add debugfs interface to expose ITS tables arm64: errata: Work around AmpereOne's erratum AC04_CPU_23 KVM: arm64: nv: Remove clearing of ICH_LR<n>.EOI if ICH_LR<n>.HW == 1 KVM: arm64: Drop sort_memblock_regions() KVM: arm64: selftests: Add test for SVE host corruption KVM: arm64: Force HCR_EL2.xMO to 1 at all times in VHE mode KVM: arm64: Replace ternary flags with str_on_off() helper Signed-off-by: Marc Zyngier <maz@kernel.org> |

Merge branch kvm-arm64/mte-frac into kvmarm-master/next
* kvm-arm64/mte-frac: : . : Prevent FEAT_MTE_ASYNC from being accidently exposed to a guest, : courtesy of Ben Horgan. From the cover letter: : : "The ID_AA64PFR1_EL1.MTE_frac field is currently hidden from KVM. : However, when ID_AA64PFR1_EL1.MTE==2, ID_AA64PFR1_EL1.MTE_frac==0 : indicates that MTE_ASYNC is supported. On a host with : ID_AA64PFR1_EL1.MTE==2 but without MTE_ASYNC support a guest with the : MTE capability enabled will incorrectly see MTE_ASYNC advertised as : supported. This series fixes that." : . KVM: selftests: Confirm exposing MTE_frac does not break migration KVM: arm64: Make MTE_frac masking conditional on MTE capability arm64/sysreg: Expose MTE_frac so that it is visible to KVM Signed-off-by: Marc Zyngier <maz@kernel.org> |

tcp: Restrict SO_TXREHASH to TCP socket.
sk->sk_txrehash is only used for TCP. Let's restrict SO_TXREHASH to TCP to reflect this. Later, we will make sk_txrehash a part of the union for other protocol families. Note that we need to modify BPF selftest not to get/set SO_TEREHASH for non-TCP sockets.
