2024-02-03Rework the exit path of tls13_handshake_recv_action()tb1-12/+14
If an error occurs in action->recv() for a handshake that needs to downgrade to legacy TLS, the artistic exit path led to hiding the error under TLS13_IO_USE_LEGACY. Rework the exit path to be easier to follow, preserving behavior except that the error can no longer be masked. Detailed analysis and initial diff by Masaru Masuda. Fixes https://github.com/libressl/openbsd/issues/146 ok beck
2024-02-03Remove last peeking at TLS1_FLAGS_SKIP_CERT_VERIFYtb1-7/+1
This was used for some GOST weirdness. The flag is unused in ports and there is no user in Debian's codesearch. ok beck

2024-02-03Remove GOST and STREEBOG support from libssl.beck21-871/+148
This version of GOST is old and not anywhere close to compliant with modern GOST standards. It is also very intrusive in libssl and makes a mess everywhere. Efforts to entice a suitably minded anyone to care about it have been unsuccessful. At this point it is probably best to remove this, and if someone ever showed up who truly needed a working version, it should be a clean implementation from scratch, and have it use something closer to the typical API in libcrypto so it would integrate less painfully here. This removes it from libssl in preparation for it's removal from libcrypto with a future major bump ok tb@
2024-02-02Ignore EVP_MD_CTX_reset() return valuetb1-6/+4

2024-02-02Reimplement BIO_dump_indent() with CBS/CBB and BIO_printf()tb1-64/+115
Instead of heaps of unchecked strlcpy/strlcat/snprintf doing hard to follow gymnastics, use a byte string, a somewhat comprehensible computation of the number of bytes to dump per output line and write using checked BIO_printf() directly to the BIO. Longer strings will still overflow the terminal width of 80 and even longer strings will still overflow the return value (undefined behavior). I don't care much about the former but the latter should be fixed in a later pass. ok beck

2024-02-01Inline EVP_PBE_find() in its last two callerstb1-140/+69
This API was already cleaned up quite a bit, but it is unused in the ecosystem and the two internal callers can be simplified a lot when inlining the lookups. EVP_PBE_CipherInit() can walk the table of "outer" PBEs and reach into the matching pbe for its cipher_nid, md_nid and keygen(). PKCS5_v2_PBKDF2_keyivgen() uses EVP_PBE_find() as a way to mapping a PRF (given by the nid of an HMAC with some digest) to the digest's nid. This can be done by a simple switch. Move MD5 to the top and GOST to the end in that switch and wrap the latter in OPENSSL_NO_GOST, so it will go away once we define OPENSSL_NO_GOST. ok beck
2024-02-01Prepare to remove the _cb() and _fp() versions of BIO_dump()tb1-33/+30
apache-httpd uses BIO_dump(), libssl uses BIO_dump_indent(), and the openssl(1) app uses both. Otherwise this is unused. This is horribly bad code even by libcrypto standards. By doing away with the callbacks fixes incorrect error checking for fwrite() but there is a lot more wrong in here. This can be cleaned up in a later pass, the only concern here is to be able to remove the unused variants in the next major bump. ok beck
2024-01-31Merge OBJ_NAME_do_all*(3) into EVP_CIPHER_do_all(3)tb5-63/+96
This is the only OBJ_NAME API that will remain after the next major bump. The API is misnamed and really is about EVP, so move it to an EVP manual documenting another API doing essentially the same thing. Remove most cross references to OBJ_NAME_*.

2024-01-30Make EVP_{CIPHER,MD}_CTX_{cleanup,reset}() NULL-safetb2-3/+8
We have a bunch of code that relies on this. Surely there is code out there in the wider ecosystem that relies on these being NULL-safe by now since upstream sprinkles NULL checks wherever they can. ok beck joshua
2024-01-30Restore SSL_shutdown() two step sequence.jsing1-1/+3
Change SSL_shutdown() such that it will return 0 after sending a close-notify, before potentially returning 1 (indicating that a close-notify has been sent and received) on a subsequent call. Some software depends on this behaviour, even though there are cases where the first call could immediately return 1 (for example, when the peer has already sent a close-notify prior to SSL_shutdown() being called). ok tb@
2024-01-30Add a shutdown sequence regress test.jsing1-3/+133
Some software relies on SSL_shutdown() returning 0 (indicating close-notify sent) before returning 1 on a subsequent call (indicating close-notify sent and received). It is worth noting that there is no guarantee that this will occur in normal operation, as the peer could send a close-notify prior to SSL_shutdown() being called. This is currently failing for TLSv1.3.
