This special case for umul_ppmm for MIPS64r6 was added in commit bbc25bee37d2b ("lib/mpi: Fix umul_ppmm() for MIPS64r6"), due to GCC being inefficient and emitting a __multi3 intrinsic. There is no such issue with clang; with this patch applied, I can build this configuration without any problems and there are no link errors like mentioned in the commit above (which I can still reproduce with GCC 9.3.0 when that commit is reverted). Only use this definition when GCC is being used. This really should have been caught by commit b0c091ae04f67 ("lib/mpi: Eliminate unused umul_ppmm definitions for MIPS") when I was messing around in this area but I was not testing 64-bit MIPS at the time.

2020-04-24crypto: drbg - always seeded with SP800-90B compliant noise sourceStephan Müller2-12/+20
As the Jitter RNG provides an SP800-90B compliant noise source, use this noise source always for the (re)seeding of the DRBG. To make sure the DRBG is always properly seeded, the reseed threshold is reduced to 1<<20 generate operations. The Jitter RNG may report health test failures. Such health test failures are treated as transient as follows. The DRBG will not reseed from the Jitter RNG (but from get_random_bytes) in case of a health test failure. Though, it produces the requested random number. The Jitter RNG has a failure counter where at most 1024 consecutive resets due to a health test failure are considered as a transient error. If more consecutive resets are required, the Jitter RNG will return a permanent error which is returned to the caller by the DRBG. With this approach, the worst case reseed threshold is significantly lower than mandated by SP800-90A in order to seed with an SP800-90B noise source: the DRBG has a reseed threshold of 2^20 * 1024 = 2^30 generate requests. Yet, in case of a transient Jitter RNG health test failure, the DRBG is seeded with the data obtained from get_random_bytes. However, if the Jitter RNG fails during the initial seeding operation even due to a health test error, the DRBG will send an error to the caller because at that time, the DRBG has received no seed that is SP800-90B compliant.

2020-04-24crypto: jitter - SP800-90B complianceStephan Müller2-101/+343
SP800-90B specifies various requirements for the noise source(s) that may seed any DRNG including SP800-90A DRBGs. In November 2020, SP800-90B will be mandated for all noise sources that provide entropy to DRBGs as part of a FIPS 140-[2|3] validation or other evaluation types. Without SP800-90B compliance, a noise source is defined to always deliver zero bits of entropy. This patch ports the SP800-90B compliance from the user space Jitter RNG version 2.2.0. The following changes are applied: - addition of (an enhanced version of) the repetitive count test (RCT) from SP800-90B section 4.4.1 - the enhancement is due to the fact of using the stuck test as input to the RCT. - addition of the adaptive proportion test (APT) from SP800-90B section 4.4.2 - update of the power-on self test to perform a test measurement of 1024 noise samples compliant to SP800-90B section 4.3 - remove of the continuous random number generator test which is replaced by APT and RCT Health test failures due to the SP800-90B operation are only enforced in FIPS mode. If a runtime health test failure is detected, the Jitter RNG is reset. If more than 1024 resets in a row are performed, a permanent error is returned to the caller.

There are two problems in crypto_spawn_alg. First of all it may return spawn->alg even if spawn->dead is set. This results in a double-free as detected by syzbot. Secondly the setting of the DYING flag is racy because we hold the read-lock instead of the write-lock. We should instead call crypto_shoot_alg in a safe manner by gaining a refcount, dropping the lock, and then releasing the refcount. This patch fixes both problems.

2020-04-16crypto: algapi - Avoid spurious modprobe on LOADEDEric Biggers1-1/+1
Currently after any algorithm is registered and tested, there's an unnecessary request_module("cryptomgr") even if it's already loaded. Also, CRYPTO_MSG_ALG_LOADED is sent twice, and thus if the algorithm is "crct10dif", lib/crc-t10dif.c replaces the tfm twice rather than once. This occurs because CRYPTO_MSG_ALG_LOADED is sent using crypto_probing_notify(), which tries to load "cryptomgr" if the notification is not handled (NOTIFY_DONE). This doesn't make sense because "cryptomgr" doesn't handle this notification. Fix this by using crypto_notify() instead of crypto_probing_notify().
