ARM32/Thumb2: Generated code now omits the frame pointer attribute on
each function. Remove global use in configure.ac.
RISC-V 64: Omit the frame pointer on the one function that uses the
register 's0'.
- random.c: use getrandom when available and fall back to direct file access
- openssh.yml: run more tests
- openssh.yml: add 10.0p2 and 9.9p2
- configure.ac: detect if `getrandom` is available on the system
- configure.ac: openssh requires WC_RNG_SEED_CB to always use `getrandom` so that the RNG doesn't get killed by SECCOMP
wolfcrypt/src/random.c: in Hash_DRBG_Generate(), always put digest[] on the stack even in WOLFSSL_SMALL_STACK configuration (it's only 32 bytes);
configure.ac: default smallstackcache on when linuxkm-defaults.
configure.ac: set DEFAULT_ENABLED_ALL_ASM=no if FIPS <v6 and not on amd64 (i.e. if ARM);
tests/api/test_sha256.c: skip test_wc_Sha256_Flags() and test_wc_Sha224_Flags() if armasm and FIPS <v7;
wolfssl/wolfcrypt/settings.h: define WOLFSSL_SP_INT_DIGIT_ALIGN for ARM (needed on BE, and no effect on LE).
configure.ac:
* in FIPS setup, fix sensing of ENABLED_CURVE25519 and ENABLED_CURVE448 to prevent noasm sneaking through, and allow fips=dev to enable them via override;
* enable-all enables ECH only if !FIPS;
* enable-all-crypto enables curve25519/curve448 only if !FIPS;
* QUIC implication of ENABLED_CURVE25519 is inhibited if FIPS;
tests/quic.c: add !HAVE_CURVE25519 paths in test_quic_key_share() to allow FIPS QUIC.
.github/workflows: update async.yml, multi-arch.yml, multi-compiler.yml, no-malloc.yml, opensslcoexist.yml, and os-check.yml, with -pedantic and related flags, and add --enable-riscv-asm to multi-arch.yml RISC-V scenario;
configure.ac: clarify error message for "SP ASM not available for CPU."
adding WOLFSSL_NO_DH_GEN_PUB in the unlikely event it needs to be disabled;
configure.ac: in --enable-linuxkm-lkcapi-register section, remove special-case
handling for -DWOLFSSL_DH_GEN_PUB, and add support for
--enable-linuxkm-lkcapi-register=all-kconfig, which disables registration of
any algs that are disabled in the target kernel, and #errors if any algs or
registrations are disabled or incompatible in libwolfssl but enabled in the
target kernel (note, it does not #error for algorithms we don't currently
shim/implement);
linuxkm/lkcapi_glue.c: change default WOLFSSL_LINUXKM_LKCAPI_PRIORITY from 10000
to INT_MAX to make masking impossible;
linuxkm/lkcapi*glue.c: move all remaining algorithm-specific gate setup into the
respective algorithm family files, and in each family file, add
LINUXKM_LKCAPI_REGISTER_ALL_KCONFIG logic to activate shims only if the
corresponding algorithm is activated in the target kernel.
linuxkm/lkcapi_sha_glue.c: fix -Wunuseds in
wc_linuxkm_drbg_default_instance_registered() and wc_linuxkm_drbg_cleanup()
when !LINUXKM_LKCAPI_REGISTER_HASH_DRBG_DEFAULT.
* Implement --enable-linuxkm-lkcapi-register=stdrng and =stdrng-default,
LINUXKM_LKCAPI_REGISTER_HASH_DRBG, and
LINUXKM_LKCAPI_REGISTER_HASH_DRBG_DEFAULT. With "_DEFAULT", the DRBG is
installed as the systemwide default stdrng, necessitating
deregister-on-command, described below. Note that get_random_bytes() and the
associated /dev/random and /dev/urandom do not use the default stdrng, and
their back end cannot currently be replaced by a module.
* Add control nodes /sys/module/libwolfssl/install_algs and
/sys/module/libwolfssl/deinstall_algs.
* Add configure option --enable-linuxkm-lkcapi-register=sysfs-nodes-only, and
macro LINUXKM_LKCAPI_REGISTER_ONLY_ON_COMMAND, to inhibit registration at
module load time.
In configure.ac ENABLED_LINUXKM_LKCAPI_REGISTER setup, don't define
WOLFSSL_DH_GEN_PUB in old FIPS, but do define it for =all.
