* crypto: lib - rename 'mod_init' & 'mod_exit' functions to be module-specificRandy Dunlap2021-07-161-4/+4
| | | | | | | | | | | | | | | | | Rename module_init & module_exit functions that are named "mod_init" and "mod_exit" so that they are unique in both the System.map file and in initcall_debug output instead of showing up as almost anonymous "mod_init". This is helpful for debugging and in determining how long certain module_init calls take to execute.

* crypto: lib/curve25519 - Move selftest prototype into header fileHerbert Xu2020-11-201-2/+0
| | | | | | | | | This patch moves the curve25519_selftest into curve25519.h so we don't get a warning from gcc complaining about a missing prototype. Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: curve25519 - Fix selftest build errorHerbert Xu2020-01-161-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CRYPTO_CURVE25519 is y, CRYPTO_LIB_CURVE25519_GENERIC will be y, but CRYPTO_LIB_CURVE25519 may be set to m, this causes build errors: lib/crypto/curve25519-selftest.o: In function `curve25519': curve25519-selftest.c:(.text.unlikely+0xc): undefined reference to `curve25519_arch' lib/crypto/curve25519-selftest.o: In function `curve25519_selftest': curve25519-selftest.c:(.init.text+0x17e): undefined reference to `curve25519_base_arch' This is because the curve25519 self-test code is being controlled by the GENERIC option rather than the overall CURVE25519 option, as is the case with blake2s. To recap, the GENERIC and ARCH options for CURVE25519 are internal only and selected by users such as the Crypto API, or the externally visible CURVE25519 option which in turn is selected by wireguard. The self-test is specific to the the external CURVE25519 option and should not be enabled by the Crypto API. This patch fixes this by splitting the GENERIC module from the CURVE25519 module with the latter now containing just the self-test.

| | | | | | | | | | Somehow these were dropped when Zinc was being integrated, which is problematic, because testing the library interface for Curve25519 is important.. This commit simply adds them back and wires them in in the same way that the blake2s selftests are wired in. Signed-off-by: Jason A.

* crypto: curve25519 - generic C library implementationsJason A. Donenfeld2019-11-171-0/+25
This contains two formally verified C implementations of the Curve25519 scalar multiplication function, one for 32-bit systems, and one for 64-bit systems whose compiler supports efficient 128-bit integer types. Not only are these implementations formally verified, but they are also the fastest available C implementations. They have been modified to be friendly to kernel space and to be generally less horrendous looking, but still an effort has been made to retain their formally verified characteristic, and so the C might look slightly unidiomatic. The 64-bit version comes from HACL*: https://github.com/project-everest/hacl-star The 32-bit version comes from Fiat: https://github.com/mit-plv/fiat-crypto Information: https://cr.yp.to/ecdh.html Signed-off-by: Jason A.
