  Pretty big, but hard to make up any cohesive story that would explain

2a689f76ed vsock/test: add stream TX credit bounds test
Add a regression test for the TX credit bounds fix. The test verifies
that a sender with a small local buffer size cannot queue excessive
data even when the peer advertises a large receive buffer.

The client:
  - Sets a small buffer size (64 KiB)
  - Connects to server (which advertises 2 MiB buffer)
  - Sends in non-blocking mode until EAGAIN
  - Verifies total queued data is bounded

This guards against the original vulnerability where a remote peer
could cause unbounded kernel memory allocation by advertising a large
buffer and reading slowly.

0a98de8013 vsock/test: fix seqpacket message bounds test
The test requires the sender (client) to send all messages before waking
up the receiver (server).
Since virtio-vsock had a bug and did not respect the size of the TX
buffer, this test worked, but now that we are going to fix the bug, the
test hangs because the sender would fill the TX buffer before waking up
the receiver.

Set the buffer size in the sender (client) as well, as we already do for
the receiver (server).

04708606fd selftests: net: amt: wait longer for connection before sending packets
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.

Initialize _evtfd to -1 in struct dev_ctx to prevent garbage output
when running kublk in foreground mode. Without this, _evtfd is
zero-initialized to 0 (stdin), and ublk_send_dev_event() writes
binary data to stdin which appears as garbage on the terminal.

23e62cf755 selftests/ublk: fix error handling for starting device
Fix error handling in ublk_start_daemon() when start_dev fails:

1. Call ublk_ctrl_stop_dev() to cancel inflight uring_cmd before
   cleanup. Without this, the device deletion may hang waiting for
   I/O completion that will never happen.

2. Add fail_start label so that pthread_join() is called on the
   error path. This ensures proper thread cleanup when startup fails.

5d54aa40c7 vsock/test: Do not filter kallsyms by symbol type
Blamed commit implemented logic to discover available vsock transports by
grepping /proc/kallsyms for known symbols. It incorrectly filtered entries
by type 'd'.

For some kernel configs having

    CONFIG_VIRTIO_VSOCKETS=m
    CONFIG_VSOCKETS_LOOPBACK=y

kallsyms reports

    0000000000000000 d virtio_transport	[vmw_vsock_virtio_transport]
    0000000000000000 t loopback_transport

Overzealous filtering might have affected vsock test suit, resulting in
insufficient/misleading testing.

Do not filter symbols by type. It never helped much.

selftests to fail, as x86 Makefile overwrites CFLAGS using ":=", dropping the

a63e5fe095 vsock/test: Add test for a linear and non-linear skb getting coalesced
Loopback transport can mangle data in rx queue when a linear skb is
followed by a small MSG_ZEROCOPY packet.

To exercise the logic, send out two packets: a weirdly sized one (to ensure
some spare tail room in the skb) and a zerocopy one that's small enough to
fit in the spare room of its predecessor. Then, wait for both to land in
the rx queue, and check the data received. Faulty packets merger manifests
itself by corrupting payload of the later packet.

21c68ad1d9 tools/testing/selftests: fix gup_longterm for unknown fs
Commit 66bce7afba ("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.

fb39444732 tools/testing/selftests: add forked (un)/faulted VMA merge tests
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.

0ace8f2db6 tools/testing/selftests: add tests for !tgt, src mremap() merges
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.

8441c7d3bd cxl: Check for invalid addresses returned from translation functions on errors
Translation functions may return an invalid address in case of errors.
If the address is not checked the further use of the invalid value
will cause an address corruption.

Consistently check for a valid address returned by translation
functions. Use RESOURCE_SIZE_MAX to indicate an invalid address for
type resource_size_t. Depending on the type either RESOURCE_SIZE_MAX
or ULLONG_MAX is used to indicate an address error.

Propagating an invalid address from a failed translation may cause
userspace to think it has received a valid SPA, when in fact it is
wrong. The CXL userspace API, using trace events, expects ULLONG_MAX
to indicate a translation failure. If ULLONG_MAX is not returned
immediately, subsequent calculations can transform that bad address
into a different value (!ULLONG_MAX), and an invalid SPA may be
returned to userspace. This can lead to incorrect diagnostics and
erroneous corrective actions.

a1025dcd37 selftests: kvm: replace numbered sync points with actions
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.

75df712cdd selftests: netdevsim: add carrier state consistency test
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.

ab86d0bf01 selftests/bpf: Update xdp_context_test_run test to check maximum metadata size
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.

2fa98059fd selftests: mptcp: Mark xerror and die_perror __noreturn
Compiler reports potential uses of uninitialized variables in
mptcp_connect.c when xerror() is called from failure paths.

mptcp_connect.c:1262:11: warning: variable 'raw_addr' is used
      uninitialized whenever 'if' condition is false
      [-Wsometimes-uninitialized]

xerror() terminates execution by calling exit(), but it is not visible
to the compiler & assumes control flow may continue past the call.

Annotate xerror() with __noreturn so the compiler can correctly reason
about control flow and avoid false-positive uninitialized variable
warnings.
