This allows us to implement RSA-PSS in the FIPS module without pulling
in EVP_PKEY. It also allows people to use RSA-PSS on an RSA*.
Empirically folks seem to use the low-level padding functions a lot,
which is unfortunate.
This allows us to remove a now redundant length check in p_rsa.c.

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.)
Fix C references of OPENSSL_ia32cap_addr with a function. This is
analogous to the BSS getters. A follow-up commit will fix perlasm with a
different scheme which avoids calling into a function (clobbering
registers and complicating unwind directives.)

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.

version-specific methods set the minimum and maximum version to their

treat it as all versions disabled. To help debugging, the error code is
switched from WRONG_SSL_VERSION to a new NO_SUPPORTED_VERSIONS_ENABLED.
This also defines OPENSSL_NO_SSL3 and OPENSSL_NO_SSL3_METHOD to kick in

(Thanks to Sam Panzer for the patch.)
At least some linkers will drop constructor functions if no symbols from
that translation unit are used elsewhere in the program. On POWER, since
the cached capability value isn't a global in crypto.o (like other
platforms), the constructor function is getting discarded.
The C++11 spec says (3.6.2, paragraph 4):
It is implementation-defined whether the dynamic initialization of a
non-local variable with static storage duration is done before the
first statement of main. If the initialization is deferred to some
point in time after the first statement of main, it shall occur
before the first odr-use (3.2) of any function or variable defined
in the same translation unit as the variable to be initialized.
Compilers appear to interpret that to mean they are allowed to drop
(i.e. indefinitely defer) constructors that occur in translation units
that are never used, so they can avoid initializing some part of a
library if it's dropped on the floor.
This change makes the hardware capability value for POWER a global in
crypto.c, which should prevent the constructor function from being
ignored.
