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.
in lkcapi_sha_glue.c:
in linuxkm_hmac_setkey_common(), ignore keylength even in FIPS modules (use
wc_HmacSetKey_ex(..., 1)) on kernel < 6.0 to work around crypto manager bug;
in wc_linuxkm_drbg_startup(), add rng workout routine using handle from
crypto_alloc_rng();
in lkcapi_*_glue.c: fix test routines to return valid wolfCrypt error codes
consistently;
in module_hooks.c, implement
* linuxkm_lkcapi_sysfs_install_node(),
* linuxkm_lkcapi_sysfs_deinstall_node(),
* FIPS_rerun_self_test_handler()
and add corresponding setup/teardown in wolfssl_init() and wolfssl_exit();
in lkcapi_glue.c:
refactor linuxkm_lkcapi_sysfs_install and linuxkm_lkcapi_sysfs_deinstall to
use the new helpers;
harden the REGISTER_ALG() and UNREGISTER_ALG() macros and the
linuxkm_lkcapi_register() and linuxkm_lkcapi_unregister() functions, and add
informational messages about number of algs registered/deregistered;
in x86_vector_register_glue.c: fix gate for irq_fpu_usable() workaround to
reflect backporting of fix in >=5.10.180 in 5.10-LTS and >=5.15.39 in 5.15-LTS
linuxkm/lkcapi_glue.c: move WOLFSSL_DEBUG_TRACE_ERROR_CODES coverage for
EINVAL/ENOMEM/EBADMSG to module_hooks.c.
* 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.
typography fixes;
static attr on const byte arrays;
refactor km_ecdsa_verify() to use a single heap allocation;
fix linuxkm_test_ecdsa_nist_driver() to copy sig and hash to a heap allocation before passing to sg_set_buf() (avoids unmapping of rodata);
in linuxkm_test_pkcs1_driver() move hash from stack to heap;
add LINUX_VERSION_CODE >= 5.4 assertion in linuxkm/lkcapi_glue.c;
streamline macro logic in linuxkm/lkcapi_sha_glue.c.
