FIPS 186-4 wants d = e^-1 (mod lcm(p-1, q-1)), not (p-1)*(q-1).
Note this means the size of d might reveal information about p-1 and
q-1. However, we do operations with Chinese Remainder Theorem, so we
only use d (mod p-1) and d (mod q-1) as exponents. Using a minimal
totient does not affect those two values.
This removes RSA_recover_crt_params. Using a minimal d breaks (or rather
reveals an existing bug in) the function.
While I'm here, rename those ridiculous variable names.

Nothing is using them. For encrypt, there's generally no need to swap
out public key operations. keygen seems especially pointless as one
could just as easily call the other function directly.
The one behavior change is RSA_encrypt now gracefully detects if called
on an empty RSA, to match the other un-RSA_METHOD-ed functions which had
similar treatments. (Conscrypt was filling in the encrypt function
purely to provide a non-crashing no-op function. They leave the public
bits blank and pass their custom keys through sufficiently many layers
of Java crypto goo that it's not obvious whether this is reachable.)
We still can't take the function pointers out, but once
96bbe03dfd
trickles back into everything, we can finally prune RSA_METHOD.
Bump BORINGSSL_API_VERSION as a convenience so I can land the
corresponding removal in Conscrypt immediately.

which is unfortunate.

We check the length for MD5+SHA1 but not the normal cases. Instead,
EVP_PKEY_sign externally checks the length (largely because the silly
RSA-PSS padding function forces it). We especially should be checking
the length for these because otherwise the prefix built into the ASN.1
prefix is wrong.
The primary motivation is to avoid putting EVP_PKEY inside the FIPS
module. This means all logic for supported algorithms should live in
crypto/rsa.
This requires fixing up the verify_recover logic and some tests,
including bcm.c's KAT bits.
(evp_tests.txt is now this odd mixture of EVP-level and RSA-level error
codes. A follow-up change will add new APIs for RSA-PSS which will allow
p_rsa.c to be trimmed down and make things consistent.)

OPENSSL_ia32cap_addr avoids any relocations within the module, at the
cost of a runtime TEXTREL, which causes problems in some cases.
(Notably, if someone links us into a binary which uses the GCC "ifunc"
attribute, the loader crashes.)
We add a OPENSSL_ia32cap_addr_delta symbol (which is reachable
relocation-free from the module) stores the difference between
OPENSSL_ia32cap_P and its own address. Next, reference
OPENSSL_ia32cap_P in code as usual, but always doing LEAQ (or the
equivalent GOTPCREL MOVQ) into a register first. This pattern we can
then transform into a LEAQ and ADDQ on OPENSSL_ia32cap_addr_delta.
ADDQ modifies the FLAGS register, so this is only a safe transformation
if we safe and restore flags first. That, in turn, is only a safe
transformation if code always uses %rsp as a stack pointer (specifically
everything below the stack must be fair game for scribbling over). Linux
delivers signals on %rsp, so this should already be an ABI requirement.
Further, we must clear the red zone (using LEAQ to avoid touching FLAGS)
which signal handlers may not scribble over.
This also fixes the GOTTPOFF logic to clear the red zone.

We only ever compute it for odd (actually, prime) modulus as part of
BN_mod_sqrt.
If we cared, we could probably drop this from most binaries. This is
used to when modular square root needs Tonelli-Shanks. Modular square
root is only used for compressed coordinates. Of our supported curves
(I'm handwaiving away EC_GROUP_new_curve_GFp here[*]), only P-224 needs
the full Tonelli-Shanks algorithm (p is 1 mod 8). That computes the
Legendre symbol a bunch to find a non-square mod p. But p is known at
compile-time, so we can just hard-code a sample non-square.
Sadly, BN_mod_sqrt has some callers outside of crypto/ec, so there's
also that. Anyway, it's also not that large of a function.
[*] Glancing through SEC 2 and Brainpool, secp224r1 is the only curve
listed in either document whose prime is not either 3 mod 4 or 5 mod 8.
Even 5 mod 8 is rare: only secp224k1. It's unlikely anyone would notice
if we broke annoying primes. Though OpenSSL does support "WTLS" curves
which has an additional 1 mod 8 case.
