- avoid must_write marks in when same instruction accesses different
stack offsets on different execution paths;
- avoid must_write marks in case same instruction accesses stack

This patch adds tags __not_msg(<msg>) and __not_msg_unpriv(<msg>).
Test fails if <msg> is found in verifier log.
If __msg_not() is situated between __msg() tags framework matches
__msg() tags first, and then checks that <msg> is not present in a
portion of a log between bracketing __msg() tags.
__msg_not() tags bracketed by a same __msg() group are effectively
unordered.
The idea is borrowed from LLVM's CheckFile with its CHECK-NOT syntax.

Remove register chain based liveness tracking:
- struct bpf_reg_state->{parent,live} fields are no longer needed;
- REG_LIVE_WRITTEN marks are superseded by bpf_mark_stack_write()
calls;
- mark_reg_read() calls are superseded by bpf_mark_stack_read();
- log.c:print_liveness() is superseded by logging in liveness.c;
- propagate_liveness() is superseded by bpf_update_live_stack();
- no need to establish register chains in is_state_visited() anymore;
- fix a bunch of tests expecting "_w" suffixes in verifier log
messages.

Currently only array maps are supported, but the implementation can be
extended for other maps and objects. The hash is memoized only for
exclusive and frozen maps as their content is stable until the exclusive
program modifies the map.
This is required for BPF signing, enabling a trusted loader program to
verify a map's integrity. The loader retrieves
the map's runtime hash from the kernel and compares it against an
expected hash computed at build time.

Currently, KF_RCU_PROTECTED only applies to iterator APIs and that too
in a convoluted fashion: the presence of this flag on the kfunc is used
to set MEM_RCU in iterator type, and the lack of RCU protection results
in an error only later, once next() or destroy() methods are invoked on
the iterator. While there is no bug, this is certainly a bit
unintuitive, and makes the enforcement of the flag iterator specific.
In the interest of making this flag useful for other upcoming kfuncs,
e.g. scx_bpf_cpu_curr() [0][1], add enforcement for invoking the kfunc
in an RCU critical section in general.
This would also mean that iterator APIs using KF_RCU_PROTECTED will
error out earlier, instead of throwing an error for lack of RCU CS
protection when next() or destroy() methods are invoked.
In addition to this, if the kfuncs tagged KF_RCU_PROTECTED return a
pointer value, ensure that this pointer value is only usable in an RCU
critical section. There might be edge cases where the return value is
special and doesn't need to imply MEM_RCU semantics, but in general, the
assumption should hold for the majority of kfuncs, and we can revisit
things if necessary later.

Currently the UAPI headers are always installed into the source directory.
When building out-of-tree this doesn't work, as the include path will be
wrong and it dirties the source tree, leading to complains by kbuild.
Make sure the 'headers' target installs the UAPI headers in the correctly.
The real target directory can come from multiple places. To handle them all
extract the target directory from KHDR_INCLUDES.

devm_cxl_add_dport_by_dev() outside of cxl_test is done through PCI
hierarchy. However with cxl_test, it needs to be done through the
platform device hierarchy. Add the mock function for
devm_cxl_add_dport_by_dev().
When cxl_core calls a cxl_core exported function and that function is
mocked by cxl_test, the call chain causes a circular dependency issue. Dan
provided a workaround to avoid this issue. Apply the method to changes from
the late dport allocation changes in order to enable cxl-test.
In cxl_core they are defined with "__" added in front of the function. A
macro is used to define the original function names for when non-test
version of the kernel is built. A bit of macros and typedefs are used to
allow mocking of those functions in cxl_test.

Group the decoder setup code in switch and endpoint port probe into a
single function for each to reduce the number of functions to be mocked
in cxl_test. Introduce devm_cxl_switch_port_decoders_setup() and
devm_cxl_endpoint_decoders_setup(). These two functions will be mocked
instead with some functions optimized out since the mock version does
not do anything. Remove devm_cxl_setup_hdm(),
devm_cxl_add_passthrough_decoder(), and devm_cxl_enumerate_decoders() in
cxl_test mock code. In turn, mock_cxl_add_passthrough_decoder() can be
removed since cxl_test does not setup passthrough decoders.
__wrap_cxl_hdm_decode_init() and __wrap_cxl_dvsec_rr_decode() can be
removed as well since they only return 0 when called.

This is a test case minimized from a syzbot reproducer from [1].
The test case triggers verifier.c:maybe_exit_scc() w/o
preceding call to verifier.c:maybe_enter_scc() on a speculative
symbolic execution path.
Here is verifier log for the test case:
Live regs before insn:
0: .......... (b7) r0 = 100
1 1: 0......... (7b) *(u64 *)(r10 -512) = r0
1 2: 0......... (b5) if r0 <= 0x0 goto pc-2
3: 0......... (95) exit
0: R1=ctx() R10=fp0
0: (b7) r0 = 100 ; R0_w=100
1: (7b) *(u64 *)(r10 -512) = r0 ; R0_w=100 R10=fp0 fp-512_w=100
2: (b5) if r0 <= 0x0 goto pc-2
mark_precise: ...
2: R0_w=100
3: (95) exit
from 2 to 1 (speculative execution): R0_w=scalar() R1=ctx() R10=fp0 fp-512_w=100
1: R0_w=scalar() R1=ctx() R10=fp0 fp-512_w=100

processed 5 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0
- Non-speculative execution path 0-3 does not allocate any checkpoints
(and hence does not call maybe_enter_scc()), and schedules a
speculative jump from 2 to 1.
- Speculative execution path stops immediately because of an infinite
loop detection and triggers verifier.c:update_branch_counts() ->
maybe_exit_scc() calls.

After using numa_set_mempolicy_home_node() the test fails to compile on
systems with libnuma library versioned lower than 2.0.16.
In order to allow lower library version add a pkg-config related check
and exclude that part of the code. Without the proper MPOL setup it
can't be tested.
Make a total number of tests two. The first one is the first batch and
the second is the MPOL related one. The goal is to let the user know if
it has been skipped due to library limitation.
Remove test_futex_mpol(), it was unused and it is now complained by the
compiler if the part is not compiled.

basic-gcs has it's own make rule to handle the special compiler
invocation to build against nolibc. This rule does not respect the
$(CFLAGS) passed by the Makefile from the parent directory.
However these $(CFLAGS) set up the include path to include the UAPI
headers from the current kernel.
Due to this the asm/hwcap.h header is used from the toolchain instead of
the UAPI and the definition of HWCAP_GCS is not found.
Restructure the rule for basic-gcs to respect the $(CFLAGS).

This commit is a rewrite almost from scratch of vmtest.sh.
By relying on virtme-ng, we get rid of boot2container, reducing the
total bootup time (and network requirements). That means that we are
relying on the programs being installed on the host, but that shouldn't
be an issue. The generation of the kconfig is also now handled by
virtme-ng, so that's one less thing to worry.
I used tools/testing/selftests/vsock/vmtest.sh as a base and modified it
to look mostly like my previous script:
- removed the custom ssh handling
- make use of vng for compiling, which allows to bring remote
compilation (and potentially remote compilation on a remote container)
- change the verbosity logic by having 2 levels:
- first one shows the tests outputs
- second level also shows the VM logs
- instead of only running the compiled kernel when it is built, if we
are in the kernel tree, use the kernel artifacts there (and complain
if they are not built)
- adapted the tests list to match the HID subsystem tests

RX devmem sometimes fails on NIPA:
https://netdev-3.bots.linux.dev/vmksft-fbnic-qemu-dbg/results/294402/7-devmem-py/
Both RSS and flow steering are properly installed, but the wait_port_listen
fails. Try to remove sleep(1) to see if the cause of the failure is
spending too much time during RX setup. I don't see a good reason to
have sleep in the first place. If there needs to be a delay between
installing the rules and receiving the traffic, let's add it to the
callers (devmem.py) instead.

The client-side function connect_one_server() properly closes its IPC
descriptor after use, but the server-side code in both mptcp_sockopt.c
and mptcp_inq.c was missing corresponding close() calls for their IPC
descriptors, leaving file descriptors open unnecessarily.
This change ensures proper cleanup by:
1. Adding missing close(pipefds[0]/unixfds[0]) in server processes
2. Adding close(pipefds[1]/unixfds[1]) after server() function calls
This ensures both ends of the IPC pipe are properly closed in their
respective processes, preventing file descriptor leaks.

The server file descriptor ('fd') is opened in server() but never closed.
While accepted connections are properly closed in process_one_client(),
the main listening socket remains open, causing a resource leak.
This patch ensures the server fd is properly closed after processing
clients, bringing the sockopt and inq test cases in line with proper
resource cleanup practices.
