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: Add kernel-doc for this new public API, including mod_name and the
return value. Document normalization, built-in modules, and the current
false return when /proc/modules cannot be read.

Low: The actual caller is do_cleanup(), in the library parent process,
not do_test_cleanup(), which invokes the test's cleanup callback.
Correct the lifecycle description.

Medium: This commit already has 19 mappings, so a valid requirement list
with all 19 available as modules passes the config check but queues only
16, silently omitting three required loads. Size the storage from the
mapping table or allocate enough space instead of discarding entries.
> kconfig_module_check(&vars[i]);
> + kconfig_module_record(vars[i].id);
Medium: kconfig_module_check() can change choice to 'n' for an uninstalled
module, but this still queues it. For CONFIG_MMU | CONFIG_CAN_RAW with
MMU=y and an uninstalled CAN_RAW=m, the expression succeeds, then loading
can-raw aborts the otherwise runnable test. Queue only configs that
remain enabled after checking, without making optional branches mandatory.

High: If one modprobe succeeds and a later one aborts, modules_loaded is
still false, so the cleanup helper returns without unloading the earlier
module. Track each successful load immediately and let abort cleanup
unload that successful prefix, not unattempted entries.

Medium: modprobe also inserts dependencies, but this removes only the
explicitly recorded names. With CONFIG_CAN=m and CONFIG_CAN_RAW=m,
loading can-raw also loads can; removing can-raw leaves the newly loaded,
unused can module behind. Track newly loaded dependencies and remove
only test-owned modules in dependency order.

Low: Root is needed for module insertion, but loopback VSOCK on
nonprivileged ports in the initial namespaces does not require root;
an ordinary nonroot process is not an unprivileged user namespace.
Correct the commit message and document the loading-only requirement in
the test description. Drop privileges for the reproducer after the
framework has loaded the modules.
Verdict - Needs revision
Pre-existing issue: sctphantom's description requests manual module
preloading, although its setup already loaded sctp before this series.

No need, funtion name is clear enough.

No. We would do the unload in the lib-cleanup but not test_cleanup.

True in theory, but rarely happens in practice. In LTP tests, I haven't
seen any test load more than 16 modules.
But to be on safe side, let's use 32.

Good point, let's adding back v1 check:
kconfig_runtime_check(&vars[i]);
kconfig_module_check(&vars[i]);
+ if (vars[i].choice == 'm')
+ kconfig_module_record(vars[i].id);

No. tst_modprobe() never calls tst_brk() internally, so a failed load
doesn't trigger the abort path at all, execution just continues.

Ok, maybe we can consider `modprobe -r`.

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.

Map CONFIG_VSOCKETS and CONFIG_VSOCKETS_LOOPBACK to their kernel
modules (vsock, vsock_loopback), so that tst_kconfig can load them
automatically when the test declares the matching configs.
cve-2025-21756 binds to VMADDR_CID_LOCAL, which requires the
vsock_loopback module. When the module is present but not loaded,
bind() fails with EADDRNOTAVAIL and the test aborts with TBROK
instead of exercising the CVE, so declare both configs in the test's
needs_kconfigs.
The test also needs root to load the modules and to run as the
vsock_loopback transport is not available from an unprivileged user
namespace.

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.
