We already record output of ip link for NETIF in env for easy access.
Record the detailed version. TSO test will want to know the max tso size.

Find out and record in env the name of the interface which remote host
will use for the IP address provided via config.
Interface name is useful for mausezahn and for setting up tunnels.

Commit f2868b1a66d4f40f ("perf tools: Expose quiet/verbose variables in
Makefile.perf") moved the quiet infrastructure out of
tools/build/Makefile.build and into the top-level Makefile.perf file so
that the quiet infrastructure could be used throughout perf and not just
in Makefile.build.
Extract out the quiet infrastructure into Makefile.include so that it
can be leveraged outside of perf.

This helper could be useful to more than just forwarding tests.
Move it upstairs and port over to log_test_skip().
Split the function into two parts: the bit that actually checks and
reports skip, which is in a new function check_command(). And a bit
that exits the test script if the check fails. This allows users
consistent checking behavior while giving an option to bail out from
a single test without bailing out of the whole script.

Verify that for a connectible AF_VSOCK socket, merely having a transport
assigned is insufficient; socket must be connected for the sockmap to
accept.
This does not test datagram vsocks. Even though it hardly matters. VMCI is
the only transport that features VSOCK_TRANSPORT_F_DGRAM, but it has an
unimplemented vsock_transport::readskb() callback, making it unsupported by
BPF/sockmap.

Commit 515745445e92 ("selftest/bpf: Add test for vsock removal from sockmap
on close()") added test that checked if proto::close() callback was invoked
on AF_VSOCK socket release. I.e. it verified that a close()d vsock does
indeed get removed from the sockmap.
It was done simply by creating a socket pair and attempting to replace a
close()d one with its peer. Since, due to a recent change, sockmap does not
allow updating index with a non-established connectible vsock, redo it with
a freshly established one.

When testing if we should try to compact memory or drop caches before we
run the THP or HugeTLB tests we use | as an or operator. This doesn't
work since run_vmtests.sh is written in shell where this is used to pipe
the output of the first argument into the second. Instead use the shell's
-o operator.

getdelays had a compilation issue because the format string was not
updated when the "delay min" was added. For example, after adding the
"delay min" in printf, there were 7 strings but only 6 "%s" format
specifiers. Similarly, after adding the 't->cpu_delay_total', there were
7 variables but only 6 format characters specifiers, causing compilation
issues as follows. This commit fixes these issues to ensure that
getdelays compiles correctly.

When working on OpenRISC support for restartable sequences I noticed
and fixed these two issues with the riscv support bits.
1 The 'inc' argument to RSEQ_ASM_OP_R_DEREF_ADDV was being implicitly
passed to the macro. Fix this by adding 'inc' to the list of macro
arguments.
2 The inline asm input constraints for 'inc' and 'off' use "er", The
riscv gcc port does not have an "e" constraint, this looks to be
copied from the x86 port. Fix this by just using an "r" constraint.
I have compile tested this only for riscv. However, the same fixes I
use in the OpenRISC rseq selftests and everything passes with no issues.

Since commit 5155cbcdbf03 ("af_unix: Add a prompt to
CONFIG_AF_UNIX_OOB"), the Landlock selftests's configuration is not
enough to build a minimal kernel. Because scoped_signal_test checks
with the MSG_OOB flag, we need to enable CONFIG_AF_UNIX_OOB for tests:
# RUN fown.no_sandbox.sigurg_socket ...
# scoped_signal_test.c:420:sigurg_socket:Expected 1 (1) == send(client_socket, ".", 1, MSG_OOB) (-1)
# sigurg_socket: Test terminated by assertion

Now BPF only supports bpf_list_push_{front,back}_impl kfunc, not bpf_list_
push_{front,back}.
This patch fix this issue. Without this patch, if we use bpf_list kfunc
in scx, the BPF verifier would complain:
libbpf: extern (func ksym) 'bpf_list_push_back': not found in kernel or
module BTFs
libbpf: failed to load object 'scx_foo'
libbpf: failed to load BPF skeleton 'scx_foo': -EINVAL
With this patch, the bpf list kfunc will work as expected.

Starting with Rust 1.85.0 (currently in beta, to be released 2025-02-20),
under some kernel configurations with `CONFIG_RUST_DEBUG_ASSERTIONS=y`,
one may trigger a new `objtool` warning:
rust/kernel.o: warning: objtool: _R...securityNtB2_11SecurityCtx8as_bytes()
falls through to next function _R...core3ops4drop4Drop4drop()
due to a call to the `noreturn` symbol:
core::panicking::assert_failed::<usize, usize>
Thus add it to the list so that `objtool` knows it is actually `noreturn`.
Do so matching with `strstr` since it is a generic.
See commit 56d680dd23c3 ("objtool/rust: list `noreturn` Rust functions")
for more details.
Cc: stable@vger.kernel.org # Needed in 6.12.y and 6.13.y only (Rust is pinned in older LTSs).

Add testcases to x86's Hyper-V CPUID test to verify that KVM advertises
support for features that require an in-kernel local APIC appropriately,
i.e. that KVM hides support from the vCPU-scoped ioctl if the VM doesn't
have an in-kernel local APIC.

Allocate, get, and free the CPUID array in the Hyper-V CPUID test in the
test's core helper, instead of copy+pasting code at each call site. In
addition to deduplicating a small amount of code, restricting visibility
of the array to a single invocation of the core test prevents "leaking" an
array across test cases. Passing in @vcpu to the helper will also allow
pivoting on VM-scoped information without needing to pass more booleans,
e.g. to conditionally assert on features that require an in-kernel APIC.
To avoid use-after-free bugs due to overzealous and careless developers,
opportunstically add a comment to explain that the system-scoped helper
caches the Hyper-V CPUID entries, i.e. that the caller is not responsible
for freeing the memory.
