163c95691a Forbid EMS from changing during renegotation.
Changing parameters on renegotiation makes all our APIs confusing. This
one has no reason to change, so lock it down. In particular, our
preference to forbid Token Binding + renego may be overridden at the
IETF, even though it's insane. Loosening it will be a bit less of a
headache if EMS can't change.

https://www.ietf.org/mail-archive/web/unbearable/current/msg00690.html
claims that this is already in the specification and enforced by NSS. I
can't find anything to this effect in the specification. It just says
the client MUST disable renegotiation when EMS is missing, which is
wishful thinking. At a glance, NSS doesn't seem to check, though I could
be misunderstanding the code.

Nonetheless, locking this down is a good idea anyway. Accurate or not,
take the email as an implicit endorsement of this from Mozilla.

147f1c468c Simplify RC4 code and remove assembly.
This removes all but the generic C RC4 implementation. At this point we
want to optimize for size/simplicity rather than speed.

See also upstream's 3e9e810f2e047effb1056211794d2d12ec2b04e7 which
removed the RC4_CHUNK code and standardized on RC4_INDEX. A
since-removed comment says that it was implemented for "pre-21164a Alpha
CPUs don't have byte load/store instructions" and helps with SPARC and
MIPS.

This also removes all the manual loop unrolling.

kind of embarrassing. (Other curves are actually tested, but only
because runner.go tests them against BoGo.)

1db42fb3ca Clarify CBS/CBB with respect to high tag number form.
We may need to implement high tag number form someday. CBS_get_asn1 has
an unsigned output to allow for this, but CBB_add_asn1 takes a uint8_t
(I think this might be my fault). Fix that which also fixes a
-Wconversion warning.

Simply leaving room in tag representation will still cause troubles
because the class and constructed bits overlap with bits for tag numbers
above 31. Probably the cleanest option would be to shift them to the top
3 bits of a u32 and thus not quite match the DER representation. Then
CBS_get_asn1 and CBB_add_asn1 will internally munge that into the DER
representation and consumers may continue to write things like:

   tag_number | CBS_ASN1_CONTEXT_SPECIFIC

I haven't done that here, but in preparation for that, document that
consumers need to use the values and should refrain from assuming the
correspond to DER.

0fc37ef082 Fix a number of sigalg scope issues.
peer_sigalgs should live on SSL_HANDSHAKE. This both releases a little
bit of memory after the handshake is over and also avoids the bug where
the sigalgs get dropped if SSL_set_SSL_CTX is called at a bad time. See
also upstream's 14e14bf6964965d02ce89805d9de867f000095aa.

This only affects consumers using the old SNI callback and not
select_certificate_cb.

Add a test that the SNI callback works as expected. In doing so, add an
SSL_CTX version of the signing preferences API. This is a property of
the cert/key pair (really just the key) and should be tied to that. This
makes it a bit easier to have the regression test work with TLS 1.2 too.

I thought we'd fixed this already, but apparently not... :-/

93d9743def Deprecate and no-op SSL_set_verify_result.
As documented by OpenSSL, it does not interact with session resumption
correctly:
https://www.openssl.org/docs/manmaster/ssl/SSL_set_verify_result.html

Sadly, netty-tcnative calls it, but we should be able to get them to
take it out because it doesn't do anything. Two of the three calls are
immediately after SSL_new. In OpenSSL and BoringSSL as of the previous
commit, this does nothing.

The final call is in verify_callback (see SSL_set_verify). This callback
is called in X509_verify_cert by way of X509_STORE_CTX_set_verify_cb.
As soon as X509_verify_cert returns, ssl->verify_result is clobbered
anyway, so it doesn't do anything.

Within OpenSSL, it's used in testdane.c. As far as I can tell, it does
not actually do a handshake and just uses this function to fake having
done one. (Regardless, we don't need to build against that.)

This is done in preparation for removing ssl->verify_result in favor of
session->verify_result.

37646838e9 Have |SSL_get_verify_result| return |X509_V_OK| when no client certificate is given.
9498e74 changed the default value of verify_result to an error. This
tripped up NGINX, which depends on a bug[1] in OpenSSL. netty-tcnative
also uses this behavior, though it currently isn't tripped up by 9498e74
because it calls |SSL_set_verify_result|. However, we would like to
remove |SSL_set_verify_result| and with two data points, it seems this
is behavior we must preserve.

This change sets |verify_result| to |X509_V_OK| when a) no client
certificate is requested or b) none is given and it's optional.

9b01c6148e Clarify origin of optimized computation of Montgomery n0.
I found an earlier reference for an algorithm for the optimized
computation of n0 that is very similar to the one in the "Montgomery
Multiplication" paper cited in the comments. Add a reference to it.

Henry S. Warren, Jr. pointed out that his "Montgomery Multiplication"
paper is not a chapter of his book, but a supplement to the book.
Correct the reference to it.

8fcc755cf5 Don't add ERR_R_INTERNAL_ERROR to BN_R_NO_INVERSE.
This was causing some Android breakage. The real bug is actually
entirely in Android for getting its error-handling code wrong and not
handling multiple errors. I'll fix that. (See b/30917411.)

That said, BN_R_NO_INVERSE is a perfectly legitimate reason for those
operations to fail, so ERR_R_INTERNAL_ERROR isn't really a right thing
to push in front anyway. We're usually happy enough with single-error
returns (I'm still a little skeptical of this queue idea), so let's just
leave it at that.

e73c7f4281 Flesh out missing TLS 1.3 state machine coverage.
The TLS 1.3 state machine is actually less in need of the aggressive
state machine coverage tests, but nonetheless, we should cover all
handshake shapes. PSK resumption and HelloRetryRequest were missing.

We were also accidentally running "DTLS" versions of the TLS 1.3 tests
but silently running TLS 1.2.

explicitly test that TLS 1.2 tickets aren't offered in the TLS 1.3 slot
and vice versa.

958aaf1ea1 Check for errors in BN_bn2dec()
If an oversize BIGNUM is presented to BN_bn2dec() it can cause
BN_div_word() to fail and not reduce the value of 't' resulting
in OOB writes to the bn_data buffer and eventually crashing.

Fix by checking return value of BN_div_word() and checking writes
don't overflow buffer.

Thanks to Shi Lei for reporting this bug.

RT#4530

(Imported from upstream's 7123aa81e9fb19afb11fdf3850662c5f7ff1f19c.)

We've yet to enable this code, but this confirms that we do indeed need
to get our future all-variants stuff working on Windows as well as
Linux and find an AVX2-capable CI setup on each.

The crash here is caused by some win64-only code using %rax as a frame
pointer (perlasm injects a mov rax,rsp in the prologue of every win64
function).

depth on this function in 81f69e5b69b8e87ca5d7080ab643ebda7808542c.  It
looks like deeply nested BER constructed strings could cause unbounded
stack usage. Delete the function rather than import the fix.

1b93a42b37 Don't use function wrappers for EC_METHOD.
The weird function thing is a remnant of OpenSSL and I think something
weird involving Windows and symbols exported from dlls. These aren't
exposed in the public API, so have everything point to the tables
directly.

This is in preparation for making built-in EC_GROUPs static. (The static
EC_GROUPs won't be able to call a function wrapper.)
