Add a test case that can support different types of faulty links for all
protocol versions (HSRv0, HSRv1, PRPv1). It starts with a baseline with
fully functional links. The first faulty case is one link being cut during
the ping. This test uses a different function for ping that sends more
packets in shorter intervals to stress the duplicate detection algorithms a
bit more and allow for future tests with other link faults (packet loss,
reordering, etc.).
As the link fault tests now cover the cut link for HSR and PRP, it can be
removed from the hsr_ping test. Note that the removed cut link test did not
really test the fault because do_ping_long takes about 1sec while the link
is only cut after a 3sec sleep.

Previously the hsr_ping test only checked that all nodes in a VLAN are
reachable (using do_ping). Update the test to also check that there is no
packet loss and no duplicate packets by running the same tests for VLANs as
without VLANs (including using do_ping_long). This also adds tests for IPv6
over VLAN. To unify the test code, the topology without VLANs now uses IP
addresses from dead:beef:0::/64 to align with the 100.64.0.0/24 range for
IPv4. Error messages are updated across the board to make it easier to find
what actually failed.
Also update the VLAN test to only run in VLAN 2, as there is no need to
check if ping really works with VLAN IDs 2, 3, 4, and 5. This lowers the
number of long ping tests on VLANs to keep the overall test runtime in
bounds.
It's still necessary to bump the test timeout a bit, though: a ping long
tests takes 1sec, do_ping_tests performs 12 of them, do_link_problem_tests
6, and the VLAN tests again 12. With some buffer for setup and waiting and
for two protocol versions, 90sec timeout seems reasonable.

Add a selftest for PRP that performs a basic ping test on IPv4 and IPv6,
over the plain PRP interface and a VLAN interface, similar to the existing
ping test for HSR. The test first checks reachability of the other node,
then checks for no loss and no duplicates.

Pull vfs mount updates from Christian Brauner:
- statmount: accept fd as a parameter
Extend struct mnt_id_req with a file descriptor field and a new
STATMOUNT_BY_FD flag. When set, statmount() returns mount information
for the mount the fd resides on — including detached mounts
(unmounted via umount2(MNT_DETACH)).
For detached mounts the STATMOUNT_MNT_POINT and STATMOUNT_MNT_NS_ID
mask bits are cleared since neither is meaningful. The capability
check is skipped for STATMOUNT_BY_FD since holding an fd already
implies prior access to the mount and equivalent information is
available through fstatfs() and /proc/pid/mountinfo without
privilege. Includes comprehensive selftests covering both attached
and detached mount cases.
- fs: Remove internal old mount API code (1 patch)
Now that every in-tree filesystem has been converted to the new
mount API, remove all the legacy shim code in fs_context.c that
handled unconverted filesystems. This deletes ~280 lines including
legacy_init_fs_context(), the legacy_fs_context struct, and
associated wrappers. The mount(2) syscall path for userspace remains
untouched. Documentation references to the legacy callbacks are
cleaned up.
- mount: add OPEN_TREE_NAMESPACE to open_tree()
Container runtimes currently use CLONE_NEWNS to copy the caller's
entire mount namespace — only to then pivot_root() and recursively
unmount everything they just copied. With large mount tables and
thousands of parallel container launches this creates significant
contention on the namespace semaphore.
OPEN_TREE_NAMESPACE copies only the specified mount tree (like
OPEN_TREE_CLONE) but returns a mount namespace fd instead of a
detached mount fd. The new namespace contains the copied tree mounted
on top of a clone of the real rootfs.
This functions as a combined unshare(CLONE_NEWNS) + pivot_root() in a
single syscall. Works with user namespaces: an unshare(CLONE_NEWUSER)
followed by OPEN_TREE_NAMESPACE creates a mount namespace owned by
the new user namespace. Mount namespace file mounts are excluded from
the copy to prevent cycles. Includes ~1000 lines of selftests"

Add a test to v_ptrace test suite to verify that ptrace accepts the
valid input combinations of vector csr registers. Use kselftest
fixture variants to create multiple inputs for the test.
The test simulates a debug scenario with three breakpoints:
0. init: let the tracee set up its initial vector configuration
1. 1st bp: modify the tracee's vector csr registers from the debugger
- resume the tracee to execute a block without vector instructions
2. 2nd bp: read back the tracees's vector csr registers from the debugger
- compare with values set by the debugger
- resume the tracee to execute a block with vector instructions
3. 3rd bp: read back the tracess's vector csr registers again
- compare with values set by the debugger
The last check helps to confirm that ptrace validation check for vector
csr registers input values works properly and maintains an accurate view
of the tracee's vector context in debugger.

KVM SVM changes for 6.20
- Drop a user-triggerable WARN on nested_svm_load_cr3() failure.
- Add support for virtualizing ERAPS. Note, correct virtualization of ERAPS
relies on an upcoming, publicly announced change in the APM to reduce the
set of conditions where hardware (i.e. KVM) *must* flush the RAP.
- Ignore nSVM intercepts for instructions that are not supported according to
L1's virtual CPU model.
- Add support for expedited writes to the fast MMIO bus, a la VMX's fastpath
for EPT Misconfig.
- Don't set GIF when clearing EFER.SVME, as GIF exists independently of SVM,
and allow userspace to restore nested state with GIF=0.
- Treat exit_code as an unsigned 64-bit value through all of KVM.
- Add support for fetching SNP certificates from userspace.
- Fix a bug where KVM would use vmcb02 instead of vmcb01 when emulating VMLOAD
or VMSAVE on behalf of L2.
- Misc fixes and cleanups.

KVM selftests changes for 6.20
- Add a regression test for TPR<=>CR8 synchronization and IRQ masking.
- Overhaul selftest's MMU infrastructure to genericize stage-2 MMU support,
and extend x86's infrastructure to support EPT and NPT (for L2 guests).
- Extend several nested VMX tests to also cover nested SVM.
- Add a selftest for nested VMLOAD/VMSAVE.
- Rework the nested dirty log test, originally added as a regression test for
PML where KVM logged L2 GPAs instead of L1 GPAs, to improve test coverage
and to hopefully make the test easier to understand and maintain.

KVM/arm64 updates for 7.0
- Add support for FEAT_IDST, allowing ID registers that are not
implemented to be reported as a normal trap rather than as an UNDEF
exception.
- Add sanitisation of the VTCR_EL2 register, fixing a number of
UXN/PXN/XN bugs in the process.
- Full handling of RESx bits, instead of only RES0, and resulting in
SCTLR_EL2 being added to the list of sanitised registers.
- More pKVM fixes for features that are not supposed to be exposed to
guests.
- Make sure that MTE being disabled on the pKVM host doesn't give it
the ability to attack the hypervisor.
- Allow pKVM's host stage-2 mappings to use the Force Write Back
version of the memory attributes by using the "pass-through'
encoding.
- Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the
guest.
- Preliminary work for guest GICv5 support.
- A bunch of debugfs fixes, removing pointless custom iterators stored
in guest data structures.
- A small set of FPSIMD cleanups.
- Selftest fixes addressing the incorrect alignment of page
allocation.
- Other assorted low-impact fixes and spelling fixes.

This warning can be seen with GCC 15.2:
mptcp_connect.c: In function ‘main_loop’:
mptcp_connect.c:1422:37: warning: ‘peer’ may be used uninitialized [-Wmaybe-uninitialized]

mptcp_connect.c:1377:26: note: ‘peer’ was declared here

This variable is set in sock_connect_mptcp() in some conditions. If not,
this helper returns an error, and the program stops. So this is a false
positive, but better removing it by initialising peer to NULL.

Update the expected result of the selftest as recursion of task local
storage syscall and helpers have been relaxed. Now that the percpu
counter is removed, task local storage helpers, bpf_task_storage_get()
and bpf_task_storage_delete() can now run on the same CPU at the same
time unless they cause deadlock.
Note that since there is no percpu counter preventing recursion in
task local storage helpers, bpf_trampoline now catches the recursion
of on_update as reported by recursion_misses.

The issue occurs in TOO_MANY_FRAGS test case when xdp_zc_max_segs is set to
an odd number.
TOO_MANY_FRAGS test case contains an invalid packet consisting of
(xdp_zc_max_segs) frags. Every frag, even the last one has XDP_PKT_CONTD
flag set. This packet is expected to be dropped. After that, there is a
valid linear packet, which is expected to be received back.
Once (xdp_zc_max_segs) is an odd number, the last packet cannot be
received, if packet forwarding between Rx and Tx interfaces relies on
the ethernet header, e.g. checks for ETH_P_LOOPBACK. Packet is malformed,
if all traffic is looped.
Turns out, sending function processes multiple invalid frags as if they
were in 2-frag packets. So once the invalid mbuf packet contains an odd
number of those, the valid packet after gets paired with the previous
invalid descriptor, and hence does not get an ethernet header generated, so
it is either dropped or malformed.
Make invalid packets in verbatim mode always have only a single frag. For
such packets, number of frags is otherwise meaningless, as descriptor flags
are pre-configured in verbatim mode and packet data is not generated for
invalid descriptors.

Referenced commit reduced the scope of the variable pkt, so now it has to
be reinitialized via pkt_stream_get_next_rx_pkt(), which also increments
some counters. When the packet is interrupted by the batch ending, pkt
stream therefore proceeds to the next packet, while xsk ring still contains
the previous one, this results in a pkt_nb mismatch.
Decrement the affected counters when packet is interrupted.

Introduce the LANDLOCK_RESTRICT_SELF_TSYNC flag. With this flag, a
given Landlock ruleset is applied to all threads of the calling
process, instead of only the current one.
Without this flag, multithreaded userspace programs currently resort
to using the nptl(7)/libpsx hack for multithreaded policy enforcement,
which is also used by libcap and for setuid(2). Using this
userspace-based scheme, the threads of a process enforce the same
Landlock policy, but the resulting Landlock domains are still
separate. The domains being separate causes multiple problems:
* When using Landlock's "scoped" access rights, the domain identity is
used to determine whether an operation is permitted. As a result,
when using LANLDOCK_SCOPE_SIGNAL, signaling between sibling threads
stops working. This is a problem for programming languages and
frameworks which are inherently multithreaded (e.g. Go).
* In audit logging, the domains of separate threads in a process will
get logged with different domain IDs, even when they are based on
the same ruleset FD, which might confuse users.

The script now requires IPV6 tunnel support, enable this.
This should have caught by CI, but as the config option is missing,
the tunnel interface isn't added. This results in an error cascade
that ends with "route change default" failure.
That in turn means the "ipv6 tunnel" test re-uses the previous
test setup so the "ip6ip6" test passes and script returns 0.
Make sure to catch such bugs, set ret=1 if device cannot be added
and delete the old default route before installing the new one.
After this change, IPV6_TUNNEL=n kernel builds fail with the expected
FAIL: flow offload for ns1/ns2 with IP6IP6 tunnel

When executing the last MPTCP selftests on older kernels, this output is
printed:
# 001 no JOIN
# join Rx [SKIP]
# join Tx [SKIP]
# fallback [SKIP]
In fact, behind each line, a few counters are checked, and likely not
all of them have been skipped because the they are not available on
these kernels. Instead, "new" and unsupported counters for these groups
are now ignored, and [ OK ] will be printed instead of [SKIP].
Note that on the MPTCP CI, when validating the dev versions, any
unsupported counter will cause the tests to fail. So this is safe not to
print 'SKIP' for these group checks.

Instead of waiting for a random amount of time (1 second), wait for an
event to be received on the other side.
To do that, when an address is announced (userspace_pm_add_addr), the
ANNOUNCED is expected. When a new subflow is created
(userspace_pm_add_sf), the SUB_ESTABLISHED event is expected.
With this, the tests can finish quicker.

It looks like most of the time, this helper was simply waiting a bit
more than one second: the previous MPJoin counter was often already at
the expected value. So at the end, it was just checking 10 times for
the MPJoin counter to change, but it was not happening. For the tests,
that was time, it was just waiting longer for nothing.
Instead, use 'wait_mpj' with the expected counter: in the tests, the MPJ
counter can easily be predicted. While at it, stop passing the netns as
argument: here the received MPJoin ACK is checked, which happens on the
server side. If later on, this needs to be checked on the client side,
the helper can be adapted for this case, but better avoid confusions now
if it is not needed.
While at it, stop using 'i' for the variable if it is not used.
With this, the tests can finish quicker.
