* Rewrite EVP_PKEY_add1_attr_by_NID()tb2024-07-141-11/+41
| | | | | | | Instead of jumping through many layers that cause headache, we can achieve the same in an entirely straightforward way without losing clarity. ok jsing
* Disable most EVP_PKEY_*attr* APItb2024-07-141-14/+17
| | | | | | | | There is a single consumer of this entire family of function, namely the openssl(1) pkcs12 command uses EVP_PKEY_add1_attr_by_NID, so leave that one intact for now. ok jsing

* libcrypto: constify most error string tablestb2024-06-241-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | These constitute the bulk of the remaining global mutable state in libcrypto. This commit moves most of them into data.rel.ro, leaving out ERR_str_{functs,libraries,reasons} (which require a slightly different approach) and SYS_str_reasons which is populated on startup. The main observation is that if ERR_load_strings() is called with a 0 lib argument, the ERR_STRING_DATA argument is not actually modified. We could use this fact to cast away const on the caller side and be done with it. We can make this cleaner by adding a helper ERR_load_const_strings() which explicitly avoids the assignment to str->error overriding the error code already set in the table. In order for this to work, we need to sprinkle some const in err/err.c. CMS called ERR_load_strings() with non-0 lib argument, but this didn't actually modify the error data since it ored in the value already stored in the table. Annoyingly, we need to cast const away once, namely in the call to lh_insert() in int_err_set_item(). Fixing this would require changing the public API and is going to be tricky since it requires that the LHASH_DOALL_FN_* types adjust. ok jsing
* Fix in-place decryption for EVP_chacha20_poly1305()tb2024-05-221-3/+3
| | | | | | | | | | | | | Take the MAC before clobbering the input value on decryption. Fixes hangs during the QUIC handshake with HAProxy using TLS_CHACHA20_POLY1305_SHA256. Found, issue pinpointed, and initial fix tested by Lucas Gabriel Vuotto: Let me take this opportunity to thank the HAProxy team for going out of their way to keep supporting LibreSSL. It's much appreciated. See https://github.com/haproxy/haproxy/issues/2569 tweak/ok jsing
* Avoid NULL dereference in EVP_PKEY_paramgen()tb2024-04-171-6/+8
| | | | | | | | If EVP_PKEY_new() returns NULL, it would be passed to the paramgen() pmeth which would typically dereference it. This is identical to a recent change in keygen(). ok jsing
* Delete a few more GOST remnantstb2024-04-141-21/+1
| | | | | | | | When I unifdefed GOST support, the tree wasn't fully unlocked, so I didn't want to touch a public header. All this code is in #ifndef OPENSSL_NO_GOST, which we define. ok jsing
* bio_enc: various basic cleanuptb2024-04-121-64/+67
| | | | | | | | Call a BIO bio rather than bi, a, or b; don't cast when assigning from or to a (void *). Drop loads of silly redundant parentheses, use better order of variable declarations. No change in the generated assembly
* Garbage collect various *_init() pmethstb2024-04-123-53/+24
| | | | | | | | It's unclear whether the functions these support were ever really used for anything else than kicking off an overenginerred state machine. ok jsing
* Fix a potential NULL-deref in EVP_PKEY_keygen()tb2024-04-121-6/+8
| | | | | | | After a EVP_PKEY_new() failure, a NULL pointer would be passed to the keygen pmeth, which could result in tears. ok beck jsing

* Restore EVP_get_cipherbyname(NULL)/EVP_get_digestbyname(NULL) handlingjca2024-03-241-1/+7
| | | | | | | | | The previous implementation used the now defunct OBJ_NAME_get() which bailed out when passed a NULL argument. Difference spotted by the regress tests in ports/net/openvpn (regular openvpn use is fine but openvpn --show-ciphers/--show-digests crashes). ok tb@

* Unhook and remove GOST and STREEBOGtb2024-03-025-539/+2
| | | | | | | | | | | | This stops compiling the GOST source. The current implementation is low quality and got in the way, especially in libssl. While we would be open for GOST support, it needs to be significantly better than what we have had and it also needs a maintainer. Add OPENSSL_NO_GOST to opensslfeatures and stop installing gost.h. Some code wrapped in #ifndef OPENSSL_NO_GOST will be removed later. ok jsing

* Remove the ameth libtb2024-03-021-43/+1
| | | | | | | | This is accessor API for ASN.1 methods needed for custom PKEYs. Nothing has ever used this. This has been neutered for months. The EVP_PKEY_asn1_* API that needs to stay was moved elsewhere. ok jsing
* Remove EVP_MD_meth* againtb2024-03-022-132/+2
| | | | | | | | | | | Erlang upstream disabled the otp_test_engine for LibreSSL >= 3.5 without explanation. It was the only reason we added this garbage API in the first place. Meanwhile libfido2 started using it for a mock up of OpenSSL 3's broken fetch design with old API. This is pointless, so all this garbage goes away again (in particular we can remove the absolutely horrifying EVP_MD_meth_set_app_datasize() again). ok jsing
