Subject: [PATCH 1/6] configure: Detect openssl sm3 support
Older openssl versions do not support sm3. The code has an option to
disable the sm3 hash but the lack of openssl support is not detected
automatically.

Subject: [PATCH 3/6] libkmod, depmod: Load modprobe.d, depmod.d from
${prefix}/lib.
There is an ongoing effort to limit use of files outside of /usr (or
${prefix} on general). Currently all modprobe.d paths are hardcoded to
outside of $prefix. Teach kmod to load modprobe.d from ${prefix}/lib.
On some distributions /usr/lib and /lib are the same directory because
of a compatibility symlink, and it is possible to craft configuration
files with sideeffects that would behave differently when loaded twice.
However, the override semantic ensures that one 'overrides' the other,
and only one configuration file of the same name is loaded from any of
the search directories.

Subject: [PATCH 5/6] tools: depmod: fix -Walloc-size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
GCC 14 introduces a new -Walloc-size included in -Wextra which gives:
```
tools/depmod.c:192:14: warning: allocation of insufficient size ‘1’ for type ‘struct index_node’ with size ‘1048’ [-Walloc-size]
tools/depmod.c:255:11: warning: allocation of insufficient size ‘1’ for type ‘struct index_value’ with size ‘16’ [-Walloc-size]
tools/depmod.c:286:35: warning: allocation of insufficient size ‘1’ for type ‘struct index_node’ with size ‘1048’ [-Walloc-size]
tools/depmod.c:315:44: warning: allocation of insufficient size ‘1’ for type ‘struct index_node’ with size ‘1048’ [-Walloc-size]
```
The calloc prototype is:
```
void *calloc(size_t nmemb, size_t size);
```
So, just swap the number of members and size arguments to match the prototype, as
we're initialising 1 struct of size `sizeof(struct ...)`. GCC then sees we're not
doing anything wrong.

Subject: [PATCH 6/6] libkmod: remove pkcs7 obj_to_hash_algo()
Switch to using OBJ_obj2txt() to calculate and print the pkcs7
signature hash name. This eliminates the need to duplicate libcrypto
NID to name mapping, detect SM3 openssl compile-time support, and
enables using any hashes that openssl and kernel know about. For
example SHA3 are being added for v6.7 and with this patch are
automatically supported.
