Change all left shifts to be of unsigned values.
In some cases the values were negative.
Changed 128-bit variable implementation of Curve25519. (generated)
Changed Ed25519 C implementation.
Changed Curve448 C implementation. (generated)
Changed Ed448 C implementation. (generated)
globally rename+unify:
* HAVE_LINUXKM_PIE_SUPPORT and USE_WOLFSSL_LINUXKM_PIE_REDIRECT_TABLE under gate WC_PIE_RELOC_TABLES
* WC_LKM_INDIRECT_SYM_BY_FUNC_ONLY as WC_PIE_INDIRECT_SYM_BY_FUNC_ONLY
* WC_LKM_INDIRECT_SYM_BY_DIRECT_TABLE_READ as WC_PIE_INDIRECT_SYM_BY_DIRECT_TABLE_READ
* WC_LKM_INDIRECT_SYM() as WC_PIE_INDIRECT_SYM;
linuxkm/linuxkm_wc_port.h:
* implement pointer-caching inline wolfssl_linuxkm_get_pie_redirect_table_local() for the WC_PIE_INDIRECT_SYM_BY_FUNC_ONLY path;
* for FIPS_VERSION3_GE(6,0,0), add wolfCrypt_FIPS_*_ro_sanity pointers to struct wolfssl_linuxkm_pie_redirect_table, and corresponding ad hoc prototypes;
linuxkm/Makefile and linuxkm/module_hooks.c: move wc_linuxkm_pie_reloc_tab into the wolfCrypt PIE container;
linuxkm/module_hooks.c and linuxkm/linuxkm_wc_port.h: harmonize the types of __wc_{text,rodata}_{start,end} with wolfCrypt_FIPS_{first,last,ro_start,ro_end} to allow drop-in use of the all-inclusive ELF fenceposts, activated by WC_USE_PIE_FENCEPOSTS_FOR_FIPS.
wolfcrypt/src/chacha.c and wolfssl/wolfcrypt/chacha.h: implement USE_ARM_CHACHA_SPEEDUP gate;
wolfcrypt/src/kdf.c: in wc_SSH_KDF(), add early return if _HashInit() fails (fixes _HashFree() of uninited _hash);
wolfcrypt/src/sha256.c: initialize sha256->W in ARMASM variant of wc_InitSha256_ex(), and pass sha256->heap to XMALLOC/XFREE consistently.
General stack APIs pulled out into ssl_sk.c.
Other simple APIs also pulled out into ssl_sk.c.
wolfSSL_lh_retrieve also pulled out into ssl_sk.c.
Added tests of public APIs that weren't already tested.
wolfcrypt/src/port/af_alg/afalg_aes.c: check for null key arg;
configure.ac: rename BUILD_FIPS_CURRENT to BUILD_FIPS_V2_PLUS (no functional change), and remove unused ARMASM_DIST_SOURCES set up code added in #9332;
src/include.am:
* set up $(ARMASM_SHA256_C), and use it to properly include wolfcrypt/src/sha256.c alongside armasm when appropriate;
* fix gating on Curved25519 armasm (BUILD_FIPS_V6_PLUS, not BUILD_FIPS_V6);
tests/api/test_aes.c and wolfcrypt/test/test.c: gate out incompatible coverage for WOLFSSL_AFALG and WOLFSSL_KCAPI (test_wc_AesCbcEncryptDecrypt_MultiBlocks(), test_wc_AesCtrSetKey*(), test_wc_AesCtrEncrypt*(), test_wc_AesGcmEncryptDecrypt_Sizes()).
in src/include.am, add LEGACY_ARMASM_foo and NEW_ARMASM_foo helper variables, restore pre-PR9284 armasm clauses, and add or update several FIPS gates as needed;
add empty wolfcrypt/src/port/arm/{armv8-aes.c,armv8-sha256.c,armv8-sha512.c} to mollify autotools, and in wolfcrypt/src/include.am, restore them to EXTRA_DIST if FIPS v5 or v6.
Improve performance of CFB and OFB.
Only have one implementation that is used by OFB encrypt and decrypt.
Update AES testing in unit.test.
Update benchmarking of CFB and OFb to include decrypt.
Require the ciphertext length to match the RSA modulus before copying into the AF_ALG Xilinx stack buffer, preventing oversized inputs from overflowing the aligned scratch space.
