* Add a custom copy handler for AES key wraptb2020-06-051-5/+31
| | | | | | | | | | | | | This is necessary because ctx->cipher_data is an EVP_AES_WRAP_CTX containing a pointer to ctx->iv. EVP_CIPHER_CTX_copy() uses memcpy to copy cipher_data to the target struct. The result is that the copy contains a pointer to the wrong struct, which then leads to a use-after-free. The custom copy handler fixes things up to avoid that. Issue reported by Guido Vranken ok beck inoguchi jsing
* Use IANA allocated GOST ClientCertificateTypes.jsing2020-06-053-9/+15

| | | | | | | | | | | | GOST R 34.10-94 is an obsolete certificate type, unsupported by LibreSSL and by the rest of current software, so there is no point in sending in the CertificateTypes. Diff from Dmitry Baryshkov <dbaryshkov@gmail.com> Sponsored by ROSA Linux ok inoguchi@ tb@

* Enable GOST_SIG_FORMAT_RS_LE when verifying certificate signatures.jsing2020-06-052-2/+15
| | | | | | | | | | | | | | GOST cipher suites requires that CertVerify signatures be generated in a special way (see ssl3_send_client_kex_gost(), ssl3_get_cert_verify()). However, the GOST_SIG_FORMAT_RS_LE flag was not passed in case of TLS 1.2 connections (because they use different code path). Set this flag on GOST PKEYs.

Add aliases for 256-bit GOST curves (see draft-smyshlyaev-tls12-gost-suites) and rename the 512-bit curve ids to follow names defined in tc26 OID registry.

* Remove remaining error *_str_functs[]jsing2020-06-054-274/+11
| | | | | | | | | A number of years ago we dropped the concept of having function names in errors, since it is not that useful and very quickly gets out of sync when refactoring. It would seem that some new ones got imported and some missed the last clean up. ok tb@ beck@ "kill it with fire"

| | | | | | | | | | | failure rather than silently constructing a broken X509_ATTRIBUTE object that might cause NULL pointer accesses later on. This matters because X509_ATTRIBUTE_create() is used by documented API functions like PKCS7_add_attribute(3) and the NID comes straight from the user. This fixes a bug found while working on documentation. OK tb@ and "thanks" bluhm@

* When building a chain look for non-expired certificates first.jsing2020-05-311-8/+29
| | | | | | | | | | | | | | | | | | | | | Currently, when building a certificate chain we look up an issuer and if it is the only issuer certificate available we still use it even if it has expired. When X509_V_FLAG_TRUSTED_FIRST is not in use, untrusted certificates are processed first and if one of these happens to be expired it will be used to build the chain, even if there is another non-expired option in the trusted store. Rework this code so that we first look for a non-expired untrusted certificate. If one does not exist then we take a look in the trusted store to see if we would be able to build the chain and only if there is not, do we then look for an expired untrusted certificate. This makes certificate validation possible for various sites that are serving expired AddTrust certificates. Issue reported by Christian Heimes via GitHub. ok beck@ tb@

* Handle the case where we receive a valid 0 byte application data record.jsing2020-05-291-1/+10
| | | | | | | | In this situation we cannot return zero bytes, as that signals EOF. Rather we need to return TLS13_IO_WANT_POLLIN so tell the caller to call us again, at which point we'll pull up the next record. ok tb@
