* Prevent future internal use of some #definestb2021-05-021-1/+3
| | | | | | | | After jsing's recent commits, SSL3_CC_{READ,WRITE,CLIENT,SERVER} and the derived SSL3_CHANGE_CIPHER_{CLIENT,SERVER}_{READ,WRITE} are no longer used by LibreSSL and should never be used again. discussed with jsing
* Clean up tls1_change_cipher_state().jsing2021-05-025-42/+29
| | | | | | | | Replace flag gymnastics at call sites with separate read and write, functions which call the common code. Condition on s->server instead of using SSL_ST_ACCEPT, for consistency and more readable code. ok inoguchi@ tb@
* In the TLSv1.2 server, set up the key block after sending the CCS.jsing2021-05-021-7/+7
| | | | | | | This avoids calling into the key block setup code multiple times and makes the server code consistent with the client. ok inoguchi@ tb@
* Clean up dtls1_reset_seq_numbers().jsing2021-05-025-26/+22
| | | | | | | | | | Rather than doing flag gymnastics, split dtls1_reset_seq_numbers() into separate read and write functions. Move the calls of these functions into tls1_change_cipher_state() so they directly follow the change of cipher state in the record layer, which avoids having to duplicate the calls in the client and server. ok inoguchi@ tb@
* Ensure that handshake hash is non-NULL in tls1_transcript_hash_value().jsing2021-05-021-1/+4
| | | | | | | | | | There are several paths where a subtle bug could result in tls1_transcript_hash_value() being called with a NULL handshake hash - add an explicit check for this case. As noted by tb@, due to the wonders of the libcrypto EVP APIs, combined with integer promotion, we already have a NULL check - this one is just more obvious. ok tb@
* Harden tls12_finished_verify_data() by checking master key length.jsing2021-05-021-1/+4
| | | | | | | Require master key length to be greater than zero if we're asked to derive verify data for a finished or peer finished message. ok tb@
* Stop deriving peer finished twice for TLSv1.2.jsing2021-05-021-12/+1
| | | | | | | | We already derive the peer finished in ssl3_do_change_cipher_spec(), which DTLS relies on. In the case of TLS we've been doing it twice - once in ssl3_get_message() and once in ssl3_do_change_cipher_spec(). ok tb@
* Make TS_compute_imprint a bit more robust.tb2021-05-021-20/+28
| | | | | | | | | Instead of using the output parameters directly, null them out at the beginning and work with local variables which are only assigned to the output parameters on success. This way we avoid leaking stale pointers back to the caller. requested/ok jsing

* Plug leak in c2i_ASN1_OBJECTtb2021-05-011-3/+8
| | | | | | | | | | When using the object reuse facility of c2i_ASN1_OBJECT, the dynamically allocated strings a may contain are set to NULL, so we must free them beforehand. Also clear the flag, because that's what OpenSSL chose to do. From Richard Levitte OpenSSL 1.1.1 65b88a75921533ada8b465bc8d5c0817ad927947 ok inoguchi
* Prevent double free in int_TS_RESP_verify_tokentb2021-05-011-1/+2
| | | | | | | | | | If TS_compute_imprint fails after md_alg was allocated, there will be a double free in its caller. Obvious fix is to null out the output parameter md_alg just like it's already done for imprint and imprint_len.

* Clean up and harden TLSv1.2 master key derivation.jsing2021-04-305-54/+51
| | | | | | | | | | | The master key and its length are only stored in one location, so it makes no sense to handle these outside of the derivation function (the current 'out' argument is unused). This simplifies the various call sites. If derivation fails for some reason, fail hard rather than continuing on and hoping that something deals with this correctly later. ok inoguchi@ tb@

Noticed by jeremy@, and Steffan Ulrich and others. Modify the regression tests to test these cases and not check the SAN DNSnames as "hostnames" anymore (which don't support wildcards). ok jsing@, tb@
* Clean up derivation of finished/peer finished.jsing2021-04-258-116/+147
| | | | | | | | Make this process more readable by having specific client/server functions, calling the correct one based on s->server. This allows to remove various SSL_ST_ACCEPT/SSL_ST_CONNECT checks, along with duplicate code. ok inoguchi@ tb@

* Only hash known CH extensionstb2021-04-221-5/+5
| | | | | | | | | | | | | RFC 4.1.2 specifies the ways in which the extensions in the first and the second ClientHello may differ. It basically says that extensions not known to a server must not change. This in turn makes it impossible to introduce new extensions that do change. It makes little sense to enforce that extensions we don't know and care about aren't modified, so make the hashing more lenient and restrict it to the extensions we do care about. Arguably, enforcing no change in an unknown extension is incompatible with the requirement that it be ignored. ok bcook jsing
* Add a test that roundtrips a bunch of points on all builtin curvestb2021-04-212-6/+268

* Clean up TLSv1.2 certificate request handshake data.jsing2021-04-215-43/+27
| | | | | | | | | | Currently cert_req is used by clients and cert_request is used by servers. Replace this by a single cert_request used by either client or server. Remove the certificate types as they are currently unused. This also fixes a bug whereby if the number of certificate types exceeds SSL3_CT_NUMBER the number of bytes read in is insufficient, which will break decoding. ok inoguchi@ tb@

| | | | | | | | | | | | | There are numerous functions in ec/ that exist with _GF2m and _GFp variants for no good reason. The code of both variants is the same. The EC_METHODs contain a pointer to the appropriate version. This commit hides the _GF2m and _GFp variants from internal use and provides versions that work for both curve types. These will be made public in an upcoming library bump. Similar to part of OpenSSL commit 8e3cced75fb5fee5da59ebef9605d403a999391b ok jsing

* Avoid division by zero in hybrid point encodingtb2021-04-191-17/+49
| | | | | | | | | | | | | | | In hybrid and compressed point encodings, the form octet contains a bit of information allowing to calculate y from x. For a point on a binary curve, this bit is zero if x is zero, otherwise it must match the rightmost bit of of the field element y / x. The existing code only considers the second possibility. It could thus fail with a division by zero error as found by Guido Vranken's cryptofuzz. This commit adds a few explanatory comments to oct2point and fixes some KNF issues. The only actual code change is in the last hunk which adds a BN_is_zero(x) check to avoid the division by zero. ok jsing
