crypto: api - Add fips_enable flag Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode. This patch allows us to set a kernel flag incating that we are running in a fips-compliant mode from boot up. It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.

crypto: fips - Remove bogus inclusion of internal.h The header file internal.h is only meant for internal crypto API implementors such as rng.c. So fips has no business in including it. This patch removes that inclusions and instead adds inclusions of the actual features used by fips. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: fips - Move fips_enabled sysctl into fips.c There is currently a large ifdef FIPS code section in proc.c. Ostensibly it's there because the fips_enabled sysctl sits under /proc/sys/crypto. However, no other crypto sysctls exist. In fact, the whole ethos of the crypto API is against such user interfaces so this patch moves all the FIPS sysctl code over to fips.c.

crypto: fips - add FIPS test failure notification chain Crypto test failures in FIPS mode cause an immediate panic, but on some system the cryptographic boundary extends beyond just the Linux controlled domain. Add a simple atomic notification chain to allow interested parties to register to receive notification prior to us kicking the bucket.

crypto: run initcalls for generic implementations earlier Use subsys_initcall for registration of all templates and generic algorithm implementations, rather than module_init. Then change cryptomgr to use arch_initcall, to place it before the subsys_initcalls. This is needed so that when both a generic and optimized implementation of an algorithm are built into the kernel (not loadable modules), the generic implementation is registered before the optimized one. Otherwise, the self-tests for the optimized implementation are unable to allocate the generic implementation for the new comparison fuzz tests. Note that on arm, a side effect of this change is that self-tests for generic implementations may run before the unaligned access handler has been installed. So, unaligned accesses will crash the kernel. This is arguably a good thing as it makes it easier to detect that type of bug.
