From: Eric Biggers Date: Thu, 26 Mar 2026 00:15:07 +0000 (-0700) Subject: crypto: rng - Don't pull in DRBG when CRYPTO_FIPS=n X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4061bc8c03975e6491fbe9e3cd5e53d2c003c812;p=thirdparty%2Flinux.git crypto: rng - Don't pull in DRBG when CRYPTO_FIPS=n crypto_stdrng_get_bytes() is now always available: - When CRYPTO_FIPS=n it is an inline function that always calls into the always-built-in drivers/char/random.c. - When CRYPTO_FIPS=y it is an inline function that calls into either random.c or crypto/rng.c, depending on the value of fips_enabled. The former is again always built-in. The latter is built-in as well in this case, due to CRYPTO_FIPS=y. Thus, the CRYPTO_RNG_DEFAULT symbol is no longer needed. Remove it. This makes it so that CRYPTO_DRBG_MENU (and hence also CRYPTO_DRBG, CRYPTO_JITTERENTROPY, and CRYPTO_LIB_SHA3) no longer gets unnecessarily pulled into CRYPTO_FIPS=n kernels. I.e. CRYPTO_FIPS=n kernels are no longer bloated with code that is relevant only to FIPS certifications.
