Richard Levitte d8975dec0c TLS: Use EVP_PKEY_get_group_name() to get the group name
For the moment, we translate the result to a NID, because that's still
used in several locations in libssl.  Future development should change
all the internals to be name based instead.

Various sections of code assumed that at least one of dh or ec would be

a key exchange algorithm and TLS-GROUP that we don't know about.

Matt Caswell a68eee679a Move some libssl global variables into SSL_CTX
disabled_enc_mask et al were global. Now that cipher loading is done
individually for each SSL_CTX, based on the libctx configured for that
SSL_CTX this means that some things will be disabled for one SSL_CTX but
not for another. The global variables set up the potential for different
SSL_CTXs to trample on each other. We move these variables into the SSL_CTX
structure.

Matt Caswell 301fcb2843 Concentrate deprecated libssl API usage in one file
We create a new file ssl/tls_depr.c to contain functions that need to call
deprecated APIs in libssl. This enables us to remove
OPENSSL_SUPPRESS_DEPRECATED from a number of other libssl files.

The deprecated API usage is either related to ENGINEs and is needed to
continue to support applications that use such ENGINEs. Or they are needed
to support some deprecated public libssl APIs.

One other file remains in libssl that still uses deprecated APIs: s3_cbc.c
This is needed to support the deprecated SSLv3.

Matt Caswell 6ac1cd10ba Fix safestack issues in ssl.h
We fix 3 problems with safestack:
- Including an openssl header file without linking against libcrypto
  can cause compilation failures (even if the app does not otherwise need
  to link against libcrypto). See issue #8102
- Recent changes means that applications in no-deprecated builds will need
  to include additional macro calls in the source code for all stacks that
  they need to use - which is an API break. This changes avoids that
  necessity.
- It is not possible to write code using stacks that works in both a
  no-deprecated and a normal build of OpenSSL. See issue #12707.

Fixes #12707
Contains a partial fix for #8102. A similar PR will be needed for hash to
fully fix.

Benjamin Kaduk a87f3fe01a Fix NULL dereference in SSL_check_chain() for TLS 1.3
In the tls1_check_sig_alg() helper function, we loop through the list of
"signature_algorithms_cert" values received from the client and attempt
to look up each one in turn in our internal table that maps wire
codepoint to string-form name, digest and/or signature NID, etc., in
order to compare the signature scheme from the peer's list against what
is used to sign the certificates in the certificate chain we're
checking.  Unfortunately, when the peer sends a value that we don't
support, the lookup returns NULL, but we unconditionally dereference the
lookup result for the comparison, leading to an application crash
triggerable by an unauthenticated client.

Since we will not be able to say anything about algorithms we don't
recognize, treat NULL return from lookup as "does not match".

We currently only apply the "signature_algorithm_cert" checks on TLS 1.3
connections, so previous TLS versions are unaffected.  SSL_check_chain()
is not called directly from libssl, but may be used by the application
inside a callback (e.g., client_hello or cert callback) to verify that a
candidate certificate chain will be acceptable to the client.

We refactor tls_choose_sigalg to split it up and create a new function
find_sig_alg which can (optionally) take a certificate and key as
parameters and find an appropriate sig alg if one exists. If the cert and
key are not supplied then we try to find a cert and key from the ones we

structures are now opaque, and thus we can freely change their layout

inadvertently get cleared during SSL_set_SSL_CTX() (e.g., as run

Todd Short 555cbb328e Collapse ssl3_state_st (s3) into ssl_st
With the removal of SSLv2, the s3 structure is always allocated, so
there is little point in having it be an allocated pointer. Collapse
the ssl3_state_st structure into ssl_st and fixup any references.

This should be faster than going through an indirection and due to
fewer allocations, but I'm not seeing any significant performance
improvement; it seems to be within the margin of error in timing.

Benjamin Kaduk c589c34e61 Add support for the TLS 1.3 signature_algorithms_cert extension
The new extension is like signature_algorithms, but only for the
signature *on* the certificate we will present to the peer (the
old signature_algorithms extension is still used for signatures that
we *generate*, i.e., those over TLS data structures).

We do not need to generate this extension, since we are the same
implementation as our X.509 stack and can handle the same types
of signatures, but we need to be prepared to receive it, and use the received
information when selecting what certificate to present.

There is a lot of interplay between signature_algorithms_cert and
signature_algorithms, since both affect what certificate we can
use, and thus the resulting signature algorithm used for TLS messages.
So, apply signature_algorithms_cert (if present) as a filter on what
certificates we can consider when choosing a certificate+sigalg
pair.

As part of this addition, we also remove the fallback code that let
keys of type EVP_PKEY_RSA be used to generate RSA-PSS signatures -- the
new rsa_pss_pss_* and rsa_pss_rsae_* signature schemes have pulled
the key type into what is covered by the signature algorithm, so
we should not apply this sort of compatibility workaround.

Benjamin Kaduk fd5e1a8c4a Propagate TLS 1.3 sigalgs through tls1_set_sigalgs()
Our historical SSL{,_CTX}_set_sigalgs() APIs take an array of
NID pairs (hash and signature), and our parser for manually
specifying unified sigalgs (that do not necessarily correspond
to an actual signature+hash pair) was transiting via (the implementation
of) this historical API.  The TLS 1.3 draft-23 has introduced
signature schemes that have identical signature type and hash type,
differing only in the (RSA) public key OID, which prevents
the rsa_pss_pss_* schemes from being properly identified and
sent on the wire.

To fix the issue, parse sigalg strings directly into SIGALG_LOOKUP
objects, and pass around an array of uint16 wire protocol values
instead of NID pairs.  The old interface is retained for API
compatibility but will become less and less useful with time.

Benjamin Kaduk f55e99f7dd Add TLS 1.3 draft-23 PSS signature algorithms
We now have a split in the signature algorithms codepoint space for
whether the certificate's key is for rsaEncryption or a PSS-specific
key, which should let us get rid of some special-casing that we
previously needed to try to coax rsaEncryption keys into performing PSS.
(This will be done in a subsequent commit.)

Send the new PSS-with-PSS-specific key first in our list, so that
we prefer the new technology to the old one.

We need to update the expected certificate type in one test,
since the "RSA-PSS+SHA256" form now corresponds to a public key
of type rsaEncryption, so we should expect the server certificate
type to be just "RSA".  If we want to get a server certificate
type of "RSA-PSS", we need to use a new signature algorithm
that cannot be represented as signature+hash, so add a test for that
as well.
