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/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.
configure.ac:
* add ML-KEM, ML-DSA, XMSS, and LMS to --enable-all-crypto when !ENABLED_FIPS.
* swap order of --enable-kyber and --enable-mlkem handler code to put mlkem first.
* add --enable-mldsa hander code.
* remove setup code that was adding -DWOLFSSL_NO_TLS12 and -DNO_OLD_TLS to
AM_CFLAGS when ENABLED_CRYPTONLY -- NO_OLD_TLS is already defined earlier for
when ENABLED_CRYPTONLY, and WOLFSSL_NO_TLS12 breaks wc_PRF_TLS(), which is
inside-the-FIPS-boundary crypto.
linuxkm/linuxkm_wc_port.h:
* adopt the WC_SANITIZE_DISABLE and WC_SANITIZE_ENABLE setup code from
settings.h (where it didn't belong).
* fix FIPS remapping of wc_InitMutex&friends to InitMutex&friends -- inhibit
when WOLFSSL_API_PREFIX_MAP.
wolfcrypt/src/ge_operations.c: add _wc_curve25519_dummy() to fix visibility of
curve25519().
wolfcrypt/src/poly1305.c: fix visibility of several unprefixed helper routines.
wolfcrypt/test/test.c: fix gating on tls12_kdf_test() and prf_test() (both
require !WOLFSSL_NO_TLS12).
wolfssl/internal.h, wolfssl/wolfio.h: add several WOLFSSL_API_PREFIX_MAPs.
wolfssl/wolfcrypt/ge_operations.h: fix visibility of several internal asm
functions.
wolfssl/wolfcrypt/settings.h: in WOLFSSL_LINUXKM setup, add gates to avoid redef
warnings for various settings, and remove the setup for
WC_SANITIZE_{DISABLE,ENABLE} (moved to linuxkm_wc_port.h as noted above).
wolfssl/wolfcrypt/wc_port.h: add WOLFSSL_API_PREFIX_MAPs for InitMutex() and
friends.
Exposes dynamic TLS certificate loading and OCSP stapling to allow applications to load certs lazily.
The server no longer needs to load the CA to staple OCSP responses.
Adds a certificate setup callback (WOLFSSL_CERT_SETUP_CB)
Adds an OCSP status callback to load OCSP responses directly
Adds `wc_NewOCSP`, `wc_FreeOCSP`, and `wc_CheckCertOcspResponse`
Don't call verify twice on the same error
Send correct alert on status response error
remove obsolete/wrong linuxkm incompatible-feature tests and errors for enable_compkey/ENABLED_COMPKEY/HAVE_COMP_KEY;
tweak ENABLED_ENTROPY_MEMUSE_DEFAULT logic to check for RDRAND/RDSEED.
* CFLAGS get pulled in anyway with configure options, or part of the
env, we don't need to add them
* Path handling went wrong in one specific platform test run
When you do `./configure`, the options are stored in the rules file.
This then means you can use the normal Debian packaging methods.
`make deb` also now uses `dpkg-buildpackage`.
linuxkm/Makefile: in recipe (awk script) for wc_linuxkm_pie_reloc_tab.c, report and error on unexpected relocation types;
linuxkm/module_hooks.c: in wc_linuxkm_normalize_relocations():
* fix bounds checking on the input,
* recognize references pointing at the first byte after the end of the segment,
* and mask out pad bytes when rendering the 32 bit addresses;
linuxkm/wolfcrypt.lds: add 4k alignment directives just before the segment end fenceposts, to make the fenceposts more inclusive.
linuxkm/linuxkm_wc_port.h: add WC_SVR_FLAG_NONE;
wolfssl/wolfcrypt/settings.h: for WOLFSSL_LINUXKM setup for WC_RESEED_INTERVAL,
use UINT_MAX if FIPS v5-;
wolfssl/wolfcrypt/types.h: add definitions for SAVE_NO_VECTOR_REGISTERS2, and
map no-op SAVE_VECTOR_REGISTERS2() to it.
* Store in extensions the full octet string
Store in WOLFSSL_X509_EXTENSION.value always the full contents of the
OCTET STRING of the extension, instead of different type of data
depending on the type of extension. Previously this was only done for
unknown extensions.
* Avoid local variables in 'DecodeExtKeyUsageInternal'
There is a great performance loss on configs using 'WOLFSSL_NO_MALLOC',
'WOLFSSL_STATIC_MEMORY' and 'USE_FAST_MATH' if function
'DecodeExtKeyUsageInternal' uses intermediate variables. This can be
observed running the Zephyr test 'wolfssl_test/prj-no-malloc.conf'.
Avoid using intermediate variables, and use raw pointers to the final
destination instead.
* Add missing calls to 'FreeDecodedCert'
* Return error code from 'wolfSSL_ASN1_STRING_into_old_ext_fmt'
* Fix lines larger than 80
* Allow NULL parameters for 'DecodeAuthKeyId'
* Add comment explaining build option '--enable-old-extdata-fmt'
* Test full OCTET STRING in tests/api.c
* wolfSSL_X509V3_EXT_d2i: Honor 'WOLFSSL_SMALL_STACK'
* zephyr/wolfssl_test_no_malloc: Increase test timeout
* wolfSSL_X509V3_EXT_d2i: Extract repeated code into common part
* wolfcrypt: Remove 'WOLFSSL_LOCAL' from .c files
* wolfcrypt: Change location of functions to make diff easier
Optimize code knowing it is for Intel x64.
Change signing to calculate one polynomial at a time so that if it isn't
valid then we fail early.
Other minor improvements.
Move the SHA-3 4 blocks at a time assembly into SHA-3 asm file.
Make constants in assembly the same length (front pad with zeros).
* refactor the save_vector_registers_x86() algorithm to depend directly on preempt_count(), and use local_bh_enable() and preempt_disable() directly, to mitigate glitchiness around irq_fpu_usable() and crypto_simd_usable();
* eliminate the WC_FPU_ALREADY_FLAG kludge.
* improve the error and warning messages, and add some additional checks and messages for unexpected states; add VRG_PR_ERR_X and VRG_PR_WARN_X for pr_*_once() semantics on regular builds, but unlimited messages when WOLFSSL_LINUXKM_VERBOSE_DEBUG.
linuxkm/linuxkm_wc_port.h and linuxkm/module_hooks.c:
* move the spinlock-based implementation of wc_LockMutex() from linuxkm_wc_port.h to module_hooks.c, due to numerous stuboorn direct external symbol references;
* extensively refactor the kernel header #include strategy, keeping many more superfluous headers out of __PIE__ objects, and fixing unavoidable static header functions with grafted __always_inline attributes;
* add version exceptions for RHEL 9.5.
linuxkm/Kbuild:
* on x86 with CONFIG_MITIGATION_{RETPOLINE,RETHUNK}, use inline rethunks rather than none;
* refactor check for "Error: section(s) missed by containerization." using `readelf --sections --syms`, for 100% coverage, more informative error output, and suppression of false positives on printk-related cruft;
configure.ac and linuxkm/lkcapi_sha_glue.c: use LINUXKM_LKCAPI_[DONT_]REGISTER_{SHA,HMAC}_ALL to represent --enable-linuxkm-lkcapi-register=[-]all-{sha,hmac}, which allows alg families (notably SHA1) to be masked out piecemeal;
linuxkm/lkcapi_rsa_glue.c: in linuxkm_test_pkcs1pad_driver(), mitigate unused args when LINUXKM_AKCIPHER_NO_SIGNVERIFY.
* implement interception of _get_random_bytes() and get_random_bytes_user() (implicitly intercepts /dev/random and /dev/urandom):
* get_crypto_default_rng()
* get_default_drbg_ctx()
* wc__get_random_bytes()
* wc_get_random_bytes_user()
* wc_extract_crng_user()
* wc_mix_pool_bytes()
* wc_crng_reseed()
* wc_get_random_bytes_by_kprobe()
* wc_get_random_bytes_user_kretprobe_enter()
* wc_get_random_bytes_user_kretprobe_exit()
* add LINUXKM_DRBG_GET_RANDOM_BYTES sections to wc_linuxkm_drbg_startup() and wc_linuxkm_drbg_cleanup()
* add linuxkm/patches/*/WOLFSSL_LINUXKM_HAVE_GET_RANDOM_CALLBACKS-*.patch, initially for versions:
* 5.10.17
* 5.10.236
* 5.15
* 5.17
* 6.1.73
* 6.12
* 6.15
* remove "*.patch" from .gitignore.
* add linuxkm/patches/regen-patches.sh.
* in wc_linuxkm_drbg_ctx_clear(), check lock count before freeing.
* in get_drbg() and put_drbg(), use migrate_disable(), not DISABLE_VECTOR_REGISTERS().
* in wc_linuxkm_drbg_generate(), explicitly DISABLE_VECTOR_REGISTERS() for the crypto_default_rng.
* in wc_linuxkm_drbg_generate(), add DRBG reinitialization code to handle RNG_FAILURE_E. This handles the situation where a DRBG was instantiated in a vector-ops-allowed context, caching a vectorized SHA256 ethod, but later used in a no-vector-ops-allowed context.
* in wc_linuxkm_drbg_seed(), add DISABLE_VECTOR_REGISTERS() wrapper around wc_RNG_DRBG_Reseed() for crypto_default_rng.
linuxkm/x86_vector_register_glue.c:
* add crash recovery logic to wc_linuxkm_fpu_state_assoc_unlikely()
* in wc_linuxkm_fpu_state_assoc(), when wc_linuxkm_fpu_states is null, don't call wc_linuxkm_fpu_state_assoc_unlikely() if !assume_fpu_began.
* in can_save_vector_registers_x86(), save_vector_registers_x86(), and restore_vector_registers_x86(), check for hard interrupt context first, to return early failure if current->pid is unusable.
* in save_vector_registers_x86(), tweak logic around WC_FPU_INHIBITED_FLAG, adding local_bh_disable()...local_bh_enable() to provide for safe recursion.
wolfcrypt/src/random.c: optimization: in Hash_df(), for WOLFSSL_LINUXKM, don't put digest[WC_SHA256_DIGEST_SIZE] in the heap, keep it on the stack.
wolfssl/wolfcrypt/types.h: add WOLFSSL_NO_ASM no-op definitions for DISABLE_VECTOR_REGISTERS() and REENABLE_VECTOR_REGISTERS().
configure.ac:
* move --enable-linuxkm and --enable-linuxkm-defaults initial detection early, so that HMAC_COPY_DEFAULT picks it up.
* add ENABLED_ENTROPY_MEMUSE_DEFAULT, and enable it by default when ENABLED_LINUXKM_DEFAULTS.
* update linuxkm-lkcapi-register help message.
linuxkm/linuxkm_wc_port.h:
* add my_kallsyms_lookup_name().
* add preempt_count, _raw_spin_lock_irqsave, _raw_spin_trylock, _raw_spin_unlock_irqrestore, and _cond_resched, to wolfssl_linuxkm_pie_redirect_table, and add spin_unlock_irqrestore() macro to mask native inline.
* move linuxkm mutex wrappers from wolfcrypt/src/wc_port.c to linuxkm_wc_port.h, make them inlines, and add new default spinlock-based implementation, with old method now gated on WOLFSSL_LINUXKM_USE_MUTEXES.
* change malloc() and realloc() wrappers from GFP_KERNEL to GFP_ATOMIC.
linuxkm/lkcapi_glue.c: make misc.h/misc.c inclusion unconditional, and trim now-redundant inclusions out of lkcapi_dh_glue.c and lkcapi_ecdh_glue.c.
