* Garbage collect the unused OPENSSL_ITEMtb2022-01-141-10/+1
| | | | ok inoguchi jsing
* Make structs in comp.h opaquetb2022-01-143-30/+32
| | | | | | | This moves COMP_CTX and COMP_METHOD to comp_local.h and provides missing typedefs in ossl_typ.h. ok inoguchi jsing
* Make structs in bio.h opaquetb2022-01-143-61/+62
| | | | | | | Move BIO, BIO_METHOD and BIO_F_BUFFER_CTX to bio_local.h and provide BIO typedef in ossl_typ.h. ok inoguchi jsing
* Garbage collect the app_items field of ASN1_ADBtb2022-01-146-14/+6
| | | | | | | This is unused and was removed in OpenSSL 5b70372d when it was replaced with an ASN.1 ADB callback (which we don't support). ok inoguchi jsing
* Remove NO_ASN1_FIELD_NAMEStb2022-01-141-5/+1
| | | | | | This follows OpenSSL commit 26f2412d. ok inoguchi jsing
* Remove obsolete key formatstb2022-01-145-578/+3
| | | | | | | | | | This removes NETSCAPE_X509, NETSCAPE{,_ENCRYPTED}_PKEY, RSA_NET, Netscape_RSA things. Some of the nasty tentacles that could go in principle are used in some test suites, so we need to keep them... All this was removed as part of OpenSSL commit 0bc2f365. ok inoguchi jsing
* Remove ASN1_OBJECT internals from public visibility.tb2022-01-143-17/+19
| | | | | | | | Move the struct declaration to asn1_locl.h and add a forward declaration to ossl_typ.h. This makes struct visibility in the asn1 headers match OpenSSL. ok inoguchi jsing
* Remove HMAC_CTX_{init,cleanup}() and HMAC_init from public visibilitytb2022-01-142-6/+5
| | | | | | | | | | | | | | | | In OpenSSL commit 32fd54a9a3 HMAC_CTX_cleanup() was integrated into HMAC_CTX_init(), then HMAC_CTX_init() was renamed to HMAC_CTX_reset() in dc0099e1. LibreSSL retained them for API compatibility with OpenSSL 1.0. Not many things use them anymore. In fact, some projects that didn't want to modify their code for OpenSSL 1.1 API compatibility used the removed functions to wrap the OpenSSL 1.1 API. We had to patch some of these and this will now no longer be necessary. Also remove HMAC_cleanup(). Nothing uses this. ok inoguchi jsing
* Make structs in evp.h and hmac.h opaquetb2022-01-144-146/+142
| | | | | | This moves most structs to evp_locl.h and moves HMAC_CTX to hmac_local.h. ok inoguchi jsing
* Move BN structs to bn_lcl.htb2022-01-142-50/+46
| | | | | | This makes all structs in bn.h opaque that are also opaque in OpenSSL. ok inoguchi jsing
* Remove BIO_s_file_internaltb2022-01-141-4/+1
| | | | | | | Pointed out by schwarze. How something with this name ever made its way into a public header will remain a mystery. ok inoguchi jsing
* Remove ASN1{_const,}_check_infinite_endtb2022-01-142-30/+2
| | | | | | Suggested by schwarze ok inoguchi jsing
* Remove ASN1{,_const}_CTXtb2022-01-141-35/+1
| | | | | | | These are leftovers of the old ASN.1 stuff. Nothing uses this. OpenSSL removed them in a469a677. ok inoguchi jsing
* Remove X509_OBJECT_free_contentstb2022-01-142-19/+11
| | | | | | | | Inline X509_OBJECT_free_contents() in X509_OBJECT_free() and remove this dangerous API. It was left over when x509_vfy.h was made opaque. ok inoguchi jsing
* Remove PEM_Seal{Init,Update,Final}tb2022-01-143-223/+3
| | | | | | This unused, bug-ridden API was removed in OpenSSL commit 0674427f. ok inoguchi jsing
* Unifdef LIBRESSL_OPAQUE_* and LIBRESSL_NEXT_APItb2022-01-1410-112/+10
| | | | | This marks the start of major surgery in libcrypto. Do not attempt to build the tree for a while (~50 commits).

* Remove peer_pkeys from SSL_SESSION.jsing2022-01-116-96/+58
| | | | | | | | | | peer_pkeys comes from some world where peers can send multiple certificates - in fact, one of each known type. Since we do not live in such a world, get rid of peer_pkeys and simply use peer_cert instead (in both TLSv1.2 and TLSv1.3, both clients and servers can only send a single leaf (aka end-entity) certificate). ok inoguchi@ tb@
* Simplify SSL_get_peer_certificate()jsing2022-01-111-10/+8
| | | | ok inoguchi@ tb@
* Rename 'peer' to 'peer_cert' in SSL_SESSION.jsing2022-01-118-37/+37
| | | | | | | The 'peer' member of SSL_SESSION is the leaf/end-entity certificate provided by our peer. Rename it since 'peer' on its own is unhelpful. ok inoguchi@ tb@
* Plumb decode errors through key share parsing code.jsing2022-01-117-48/+106
| | | | | | | | | | | | Distinguish between decode errors and other errors, so that we can send a SSL_AD_DECODE_ERROR alert when appropriate. Fixes a tlsfuzzer failure, due to it expecting a decode error alert and not receiving one. Prompted by anton@ ok tb@
* Use SSL_AD_INTERNAL_ERROR for non-decoding alerts when parsing keyshares.jsing2022-01-111-4/+10
| | | | ok tb@
* Simplify tlsext_keyshare_server_parse()jsing2022-01-111-9/+5
| | | | | | | SSL_AD_DECODE_ERROR is the default alert for a TLS extension parsing failure - remove the various gotos and simply return 0 instead. ok tb@
* Convert tls_bio_cb for opaque BIOtb2022-01-101-19/+46
| | | | joint with jsing
* Document EVP_AEAD_CTX_{new,free}() and adjust example code.tb2022-01-101-6/+45
| | | | looks good to jsing
* Remove a few unused defines from x509.htb2022-01-101-6/+1
| | | | | | | | As suggested by schwarze, this removes X509_EX_V_{INIT,NETSCAPE_HACK} and X509_EXT_PACK_{STRING,UNKNOWN} ok inoguchi jsing
* Prepare to provide the EVP_MD_meth_* APItb2022-01-102-2/+130
| | | | | | | | | This allows implementations to add their own EVP_MD_METHODs. Only the setters are provided. This is used by erlang for the otp_test_engine. ok inoguchi jsing
* Prepare to provide EVP_PKEY_{public,param}_checktb2022-01-108-8/+146
| | | | | | | | | | | | | | This implements checking of a public key and of key generation parameters for DH and EC keys. With the same logic and setters and const quirks as for EVP_PKEY_check(). There are a couple of quirks: For DH no default EVP_PKEY_check() is implemented, instead EVP_PKEY_param_check() calls DH_check_ex() even though DH_param_check_ex() was added for this purpose. EVP_PKEY_public_check() for EC curves also checks the private key if present. ok inoguchi jsing
* Provide DH_check*_ex and many error codestb2022-01-104-4/+102
| | | | | | | | | | | | | | | | | | | | | DH_check{,_pub_key}_ex() wrap their non-ex versions to translate the flags argument of the original functions into OpenSSL errors. For this almost a dozen new error codes need to be added. DH_params_check{,_ex}() is a new version of DH_check that only performs a cheap subset of the checks. They are needed to implement EVP_PKEY_{public,param}_check() (observe the consistent naming) although the actual implementation of EVP_PKEY_param_check() chose to use DH_check_ex(). As far as I can tell, the only raison d'être of the _ex functions and error codes is to spew them to stderr in a couple of openssl(1) commands. This couldn't have been solved differently... These functions will not be exposed publicly. ok inoguchi jsing
* Prepare to provide EVP_PKEY_check()tb2022-01-108-12/+89
| | | | | | | | | | | | | | | | | | This allows checking the validity of an EVP_PKEY. Only RSA and EC keys are supported. If a check function is set the EVP_PKEY_METHOD, it will be used, otherwise the check function on the EVP_PKEY_ASN1_METHOD is used. The default ASN.1 methods wrap RSA_check_key() and EC_KEY_check_key(), respectively. The corresponding setters are EVP_PKEY_{asn1,meth}_set_check(). It is unclear why the PKEY method has no const while the ASN.1 method has const. Requested by tobhe and used by PHP 8.1. Based on OpenSSL commit 2aee35d3 ok inoguchi jsing
* Prevent a double free in EVP_MD_CTX_copy_ex()tb2022-01-101-1/+3
| | | | | | | | NULL out two pointer values after memcpy() to avoid a double free. In the event that both in->pctx and in->md_data are non-NULL and the calloc() of out->md_data fails, a double free could occur. ok inoguchi jsing
* zap trailing whitespacetb2022-01-101-5/+5

* ssl_check_srvr_ecc_cert_and_alg() only returns 0/1 - test accordingly.jsing2022-01-091-3/+3

* Swap arguments to ssl_check_srvr_ecc_cert_and_alg()jsing2022-01-093-9/+9
| | | | | If a libssl function takes an SSL *, it should normally be the first argument.
* Clean up ssl3_{send,get}_client_kex_gost()jsing2022-01-092-41/+46
| | | | | | | | Fix leaks, use sizeof() instead of hardcoded sizes, actually check return codes, explicit_bzero() the premaster secret on the server side and generally try to kick the GOST kex code into some sort of shape. ok inoguchi@ tb@
* Return 0/1 from ssl3_{send,get}_client_kex_gost()jsing2022-01-092-7/+7
| | | | | | | Like other KEX handling functions, there is no need to return anything other than failure/success here. ok inoguchi@ tb@

* Fix GOST skip certificate verify handling.jsing2022-01-091-19/+11
| | | | | | | | | | | GOST skip certificate verify handling got broken in r1.132 of s3_srvr.c circa 2016. Prior to this, ssl3_get_client_key_exchange() returned an 'extra special' value to indicate that the state machine should skip certificate verify. Fix this by setting and checking the TLS1_FLAGS_SKIP_CERT_VERIFY flag, which is the same as is done in the client. ok inoguchi@ tb@
* Prepare to provide EVP_MD_CTX{,_set}_pkey_ctx()tb2022-01-094-5/+55
| | | | | | | | | | | | | This API with very strange ownership handling is used by Ruby 3.1, unfortunately. For unclear reasons, it was decided that the caller retains ownership of the pctx passed in. EVP_PKEY_CTX aren't refcounted, so a flag was added to make sure that md_ctx->pctx is not freed in EVP_MD_CTX_{cleanup,reset}(). Since EVP_MD_CTX_copy_ex() duplicates the md_ctx->pctx, the flag also needs to be unset on the duplicated EVP_MD_CTX. ok inoguchi jsing
* Clean up pkey handling in ssl3_get_server_key_exchange()jsing2022-01-091-42/+22
| | | | | | | | | | With TLSv1.2 and earlier, the authentication algorithm used to sign the ServerKeyExchange message is dependent on the cipher suite in use and has nothing to do with the key exchange algorithm. As such, check the authentication algorithm based on the cipher suite in ssl3_get_server_key_exchange() and handle things accordingly. ok inoguchi@ tb@
* Prepare to provide OBJ_length() and OBJ_get0_data()tb2022-01-082-2/+28
| | | | | | | | OBJ_length() turns the int obj->length into a size_t, so add an overflow check. While obj->length should never be negative, who knows... ok jsing

* Merge SESS_CERT into SSL_SESSION.jsing2022-01-088-171/+76
| | | | | | | There is no reason for SESS_CERT to exist - remove it and merge its members into SSL_SESSION for the time being. More clean up to follow. ok inoguchi@ tb@
