Add a helper that checks whether a kernel module is loaded by
looking it up in /proc/modules. Module names are normalized so that
hyphens match the underscores used by the kernel.

Low: The new public helper has no kernel-doc comment. Document mod_name,
hyphen normalization, return values, and whether built-in modules count
as loaded.

High: If a later modprobe fails, tst_modprobe() aborts before modules_loaded
becomes true, so cleanup skips modules already loaded successfully.
Track each successful load separately and make partial-load cleanup
available before invoking the next modprobe.

High: modprobe -r also removes unused dependencies, including modules
loaded before the test and excluded from this list. For example, removing
can-raw can remove a pre-existing can module; snapshot dependency ownership
and remove only modules loaded by this test.

Medium: Every removal error is discarded, both output streams are
suppressed, and the ownership list is then cleared. Keep teardown nonfatal,
but report failed removals with TWARN and the module name instead of
silently leaving new modules loaded.

Low: Document the new root requirement in the test description: root is
needed to load the VSOCK modules, while the reproducer runs as nobody.
The commit message explains this, but the exported test description does
not.
Verdict - Needs revision
Pre-existing issue (not a patch finding):
The description in testcases/cve/sctphantom.c says to run modprobe sctp
manually, although setup() already loaded it before this series.

Tests that depend on a config set to =m must currently load the
module themselves, and may fail with misleading errors when it is
not loaded, e.g. bind() returning EADDRNOTAVAIL for AF_VSOCK when
vsock_loopback is missing.
Record the module for every config_module_maps[] entry seen as =m
during kconfig_parse_line(), load them in
tst_kconfig_module_load() via tst_modprobe(), and unload them in
reverse order from tst_kconfig_module_unload_all(), called by
do_test_cleanup(). Modules still in use are skipped without
aborting the test.
Loading and unloading are performed only as root; otherwise the
recorded list is left untouched.

This is used only once, we don't need to define a new function.
We can leave it inside kconfig_module_record().

This is better to have it inside kconfig_module_record() at the
very beginning as a gate.

Map CONFIG_VSOCKETS to "vsock" and CONFIG_VSOCKETS_LOOPBACK to
"vsock_loopback" so tst_kconfig can load them on demand.
cve-2025-21756 binds to VMADDR_CID_LOCAL and therefore needs
vsock_loopback. Without the module loaded, bind() fails with
EADDRNOTAVAIL and the test aborts with TBROK. Declare both configs in
needs_kconfigs so the modules are loaded first.
The test needs root only to load the modules; the reproducer runs as
an ordinary nonroot process in the initial namespace, which can use
loopback VSOCK on nonprivileged ports. Drop privileges to nobody after
module loading and regain root in cleanup() so the modules can be
unloaded.

To: ltp
Now that tst_kconfig loads the modules for every CONFIG_*=m entry
listed in config_module_maps[] and unloads them again at cleanup
time, tests no longer have to call tst_modprobe() from setup().
Drop the explicit tst_modprobe() calls, and the now unused
tst_module.h includes, from:
- cve-2026-46331.c: sch_ingress, cls_matchall, act_pedit
- sctphantom.c: sctp
- keyctl29.c: x509_key_parser
- keyctl30.c: pkcs8_key_parser
All four tests already declare the matching configs in
.needs_kconfigs, so tst_kconfig takes care of loading the modules
before setup() runs and unloading them once the test finishes.
BTW, with KCONFIG_SKIP_CHECK=1 the config check returns early,
so the automatic module loading is skipped as well. Users who set
that variable are expected to ensure the required modules are
loaded themselves.
