Daniel Pouzzner 4d19f55c3f linuxkm/lkcapi_aes_glue.c: in AesGcmCrypt_1(), in !WOLFSSL_AESGCM_STREAM version, don't call skcipher_walk_done(&sk_walk, ...) -- doesn't work, and not needed. 2025-05-29 12:10:02 -05:00
Daniel Pouzzner 5c0a278c7f linuxkm/lkcapi_aes_glue.c: add error path cleanups for dangling skcipher_walks. 2025-05-28 16:30:43 -05:00

Daniel Pouzzner b9b66042d7 wolfssl/wolfcrypt/dh.h: gate in wc_DhGeneratePublic() with WOLFSSL_DH_EXTRA,
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.

Daniel Pouzzner 1b59bc25d1 linuxkm:
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.

Daniel Pouzzner 1f9d0b1612 linuxkm/: fix error checking on malloc()ed values (! ptr, not IS_ERR(ptr)). 2025-04-22 17:11:52 -05:00
Daniel Pouzzner d4fc8c3791 linuxkm/: null out pointers with PTR_ERR()-encoded values before jumping to cleanup;
linuxkm/lkcapi_rsa_glue.c: in km_rsa_init(), implement error-path cleanup;

linuxkm/module_hooks.c: nix CONFIG_MODULE_SIG requirement in WOLFCRYPT_FIPS_CORE_DYNAMIC_HASH_VALUE builds;

wolfssl/wolfcrypt/settings.h: in WOLFSSL_LINUXKM setup, define WOLFSSL_ASN_INT_LEAD_0_ANY if LINUXKM_LKCAPI_REGISTER (required for kernel 5.10 crypto manager);

wolfcrypt/src/memory.c: add WC_NO_ERR_TRACE() to mock error returns in SAVE_VECTOR_REGISTERS2_fuzzer().
