Pull KVM fixes from Paolo Bonzini:
- Fix a bug where AVIC is incorrectly inhibited when running with
x2AVIC disabled via module param (or on a system without x2AVIC)
- Fix a dangling device posted IRQs bug by explicitly checking if the
irqfd is still active (on the list) when handling an eventfd signal,
instead of zeroing the irqfd's routing information when the irqfd is
deassigned.
Zeroing the irqfd's routing info causes arm64 and x86's to not
disable posting for the IRQ (kvm_arch_irq_bypass_del_producer() looks
for an MSI), incorrectly leaving the IRQ in posted mode (and leading
to use-after-free and memory leaks on AMD in particular).
This is both the most pressing and scariest, but it's been in -next
for a while.
- Disable FORTIFY_SOURCE for KVM selftests to prevent the compiler from
generating calls to the checked versions of memset() and friends,
which leads to unexpected page faults in guest code due e.g.
__memset_chk@plt not being resolved.
- Explicitly configure the supported XSS capabilities from within
{svm,vmx}_set_cpu_caps() to fix a bug where VMX will compute the
reference VMCS configuration with SHSTK and IBT enabled, but then
compute each CPUs local config with SHSTK and IBT disabled if not all
CET xfeatures are enabled, e.g. if the kernel is built with
X86_KERNEL_IBT=n.
The mismatch in features results in differing nVMX setting, and
ultimately causes kvm-intel.ko to refuse to load with nested=1.

We had a few patches in this area and no explicit coverage so far.
The test case covers the scenario addressed by the previous fix;
reusing the existing udpgro_fwd.sh script to leverage part of the
of the virtual network setup, even if such script is possibly not
a perfect fit.
Note that the mentioned script already contains several shellcheck
violation; this patch does not fix the existing code, just avoids
adding more issues in the new one.

When running this mptcp_join.sh selftest on older kernel versions not
supporting local endpoints tracking, this test fails because 3 MP_JOIN
ACKs have been received, while only 2 were expected.
It is not clear why only 2 MP_JOIN ACKs were expected on old kernel
versions, while 3 MP_JOIN SYN and SYN+ACK were expected. When testing on
the v5.15.197 kernel, 3 MP_JOIN ACKs are seen, which is also what is
expected in the selftests included in this kernel version, see commit
f4480eaad489 ("selftests: mptcp: add missing join check").
Switch the expected MP_JOIN ACKs to 3. While at it, move this
chk_join_nr helper out of the special condition for older kernel
versions as it is now the same as with more recent ones. Also, invert
the condition to be more logical: what's expected on newer kernel
versions having such helper first.

This validates the previous commit: subflow closed events should contain
an error field when a subflow got closed with an error, e.g. reset or
timeout.
For this test, the chk_evt_nr helper has been extended to check
attributes in the matched events.
In this test, the 2 subflow closed events should have an error.

This validates the previous commit: subflow closed events are re-sent
with less info when the initial subflow is disconnected after an error
and each time a subflow is closed after that.
In this new test, the userspace PM is involved because that's how it was
discovered, but it is not specific to it. The initial subflow is
terminated with a RESET, and that will cause the subflow disconnect.
Then, a new subflow is initiated, but also got rejected, which cause a
second subflow closed event, but not a third one.
While at it, in case of failure to get the expected amount of events,
the events are printed.
The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,

Some distributions (such as Ubuntu) configure GCC so that
_FORTIFY_SOURCE is automatically enabled at -O1 or above. This results
in some fortified version of definitions of standard library functions
are included. While linker resolves the symbols, the fortified versions
might override the definitions in lib/string_override.c and reference to
those PLT entries in GLIBC. This is not a problem for the code in host,
but it is a disaster for the guest code. E.g., if build and run
x86/nested_emulation_test on Ubuntu 24.04 will encounter a L1 #PF due to
memset() reference to __memset_chk@plt.
The option -fno-builtin-memset is not helpful here, because those
fortified versions are not built-in but some definitions which are
included by header, they are for different intentions.
In order to eliminate the unpredictable behaviors may vary depending on
the linker and platform, add the "-U_FORTIFY_SOURCE" into CFLAGS to
prevent from introducing the fortified definitions.

Both send_mcast4() and send_mcast6() use sleep 2 to wait for the tunnel
connection between the gateway and the relay, and for the listener
socket to be created in the LISTENER namespace.
However, tests sometimes fail because packets are sent before the
connection is fully established.
Increase the waiting time to make the tests more reliable, and use
wait_local_port_listen() to explicitly wait for the listener socket.

Fix error handling in ublk_start_daemon() when start_dev fails:
1. Call ublk_ctrl_stop_dev() to cancel inflight uring_cmd before

2. Add fail_start label so that pthread_join() is called on the

Currently, the test breaks if the SUT already has a default route
configured for IPv6. Fix by avoiding the use of the default namespace.

Commit 66bce7afbaca ("selftests/mm: fix test result reporting in
gup_longterm") introduced a small bug causing unknown filesystems to
always result in a test failure.
This is because do_test() was updated to use a common reporting path, but
this case appears to have been missed.
This is problematic for e.g. virtme-ng which uses an overlayfs file
system, causing gup_longterm to appear to fail each time due to a test
count mismatch:
# Planned tests != run tests (50 != 46)
# Totals: pass:24 fail:0 xfail:0 xpass:0 skip:22 error:0
The fix is to simply change the return into a break.

Now we correctly handle forked faulted/unfaulted merge on mremap(),
exhaustively assert that we handle this correctly.
Do this in the less duplicative way by adding a new merge_with_fork
fixture and forked/unforked variants, and abstract the forking logic as
necessary to avoid code duplication with this also.

Test that mremap()'ing a VMA into a position such that the target VMA on
merge is unfaulted and the source faulted is correctly performed.
We cover 4 cases:
1. Previous VMA unfaulted:
copied -----|
v
|-----------|.............|
| unfaulted |(faulted VMA)|
|-----------|.............|
prev
target = prev, expand prev to cover.
2. Next VMA unfaulted:
copied -----|
v
|.............|-----------|
|(faulted VMA)| unfaulted |
|.............|-----------|
next
target = next, expand next to cover.
3. Both adjacent VMAs unfaulted:
copied -----|
v
|-----------|.............|-----------|
| unfaulted |(faulted VMA)| unfaulted |
|-----------|.............|-----------|
prev next
target = prev, expand prev to cover.
4. prev unfaulted, next faulted:
copied -----|
v
|-----------|.............|-----------|
| unfaulted |(faulted VMA)| faulted |
|-----------|.............|-----------|
prev next
target = prev, expand prev to cover. Essentially equivalent to 3, but
with additional requirement that next's anon_vma is the same as the
copied VMA's.
Each of these are performed with MREMAP_DONTUNMAP set, which will cause a
KASAN assert for UAF or an assert on zero refcount anon_vma if a bug
exists with correctly propagating anon_vma state in each scenario.

Rework the guest=>host syncs in the AMX test to use named actions instead
of arbitrary, incrementing numbers. The "stage" of the test has no real
meaning, what matters is what action the test wants the host to perform.
The incrementing numbers are somewhat helpful for triaging failures, but
fully debugging failures almost always requires a much deeper dive into
the test (and KVM).
Using named actions not only makes it easier to extend the test without
having to shift all sync point numbers, it makes the code easier to read.

When /sys/kernel/tracing/buffer_size_kb is less than 12KB,
the test_multiple_writes test will stall and wait for more
input due to insufficient buffer space.
Check current buffer_size_kb value before the test. If it is
less than 12KB, it temporarily increase the buffer to 12KB,
and restore the original value after the tests are completed.

This commit adds a test case for netdevsim carrier state consistency.
Specifically, the added test verifies the carrier state during the
following operations:
1. Unlink two netdevsims
2. ifdown one netdevsim, then ifup again
3. Link the netdevsims again
4. ifdown one netdevsim, then ifup again
These steps verifies that the carrier is UP iff two netdevsims are
linked and ifuped.

Update the selftest to check that the metadata size check takes the
xdp_frame size into account in bpf_prog_test_run. The original
check (for meta size 256) was broken because the data frame supplied was
smaller than this, triggering a different EINVAL return. So supply a
larger data frame for this test to make sure we actually exercise the
check we think we are.
