Rebase MR CY25Q1 4 See merge request !30 Notable changes from the base repository: * Several includes of intel-ipsec-mb.h have been renamed to ipsec-mb.h * mp test app has been excluded from aarch64 builds due to a segfault when running. mp gets removed from the Intel repo in the future so we do not need to include this.

- fork() support on Windows is limited - split monolithic code into modules - move utility functions into separate header files (shared memory, shared memory allocations etc.) - split primary process application from the secondary one

This is to help multi-process scenarios i.e. active-passive or fail over.

At the moment, for certain data sizes, correct functionality relies on NOP (0x90) padding.

SHA256/224 one block function wasn't preserving xmm7 on Windows. This function is used of IPAD/OPAD calculations in the self test.

In some cases, original message text appeared again in the 2nd block of the message schedule.

SHA512 can now return a job just after submitting it, as a single-buffer implementation has been added (using SHA512-NI instructions). Therefore, the check after submitting a job is irrelevant.

New SM3 update function added and all major functions that depend on it: - sm3_msg_ni_avx2() and sm3_msg_submit_avx2() - sm3_hmac_submit_avx2() In the future sm3_one_block() can also be implemented. It is not on the critical path as it is used only for IPAD and OPAD calculations. Isolated SM3 tag store operation under sm3_tag_store_avx() API.
-
The implementation uses x86-64 and SSE4.2 instruction set only. It replaces previous C implementation due to numerous issues with safe-check tests. Internal API's added: - sm3_base_init() - sm3_base_update() - sm3_msg_sse() and sm3_msg_submit_sse() - sm3_one_block_sse() - sm3_hmac_submit_sse() SM3 submit and flush macros added to all MB managers and JOB API dispatching.
