* Use tls_buffer for alert and handshake fragments in the legacy stack.jsing2022-11-105-49/+94
| | | | | | This avoids a bunch of pointer munging and a handrolled memmove. ok tb@
* Finish migrating to one source file per line.joshua2022-11-101-17/+78

* In asn1.h rev. 1.65, beck@ provided ASN1_TIME_set_string_X509(3),schwarze2022-11-101-11/+139
| | | | | | | | | ASN1_TIME_normalize(3), ASN1_TIME_to_tm(3), ASN1_TIME_cmp_time_t(3), and ASN1_TIME_compare(3). Merge documentation from the OpenSSL 1.1.1 branch, which is still under a free license, with tweaks by me in several respects to match our implementation, and also using some feedback from beck@. OK beck@.

* Map objects for ED25519 to Ed25519.jsing2022-11-101-1/+7
| | | | | | | OpenSSL used ED25519, even though the RFCs use Ed25519 - as such, we get to provide both. ok tb@

* Port ASN1_buf_print() from OpenSSL 1.1.jsing2022-11-102-2/+34
| | | | | | This is needed to print byte array based keys, such as Ed25519 and X25519. ok beck@ tb@

* Revise CBS_strdup() documentation.jsing2022-11-091-6/+4
| | | | | | | CBS_strdup() now internally checks if the data contains NUL, failing if it does. Prompted by beck@
* Clean up EVP_PKEY_METHOD related tables and code.jsing2022-11-091-56/+41
| | | | | | | This is effectively the same as done for EVP_PKEY_ASN1_METHOD, although this table only has nine entries. ok tb@
* Clean up EVP_PKEY_ASN1_METHOD related tables and code.jsing2022-11-091-87/+52
| | | | | | | | | | | Rather than messing around with an OBJ_bsearch() for a table that contains 16 entries (and a stack find for any application added methods), simply do a reverse linear scan. This maintains the application method first behaviour, while removing a chunk of code. While here rename some variables and do some style clean up. ok tb@

* Rework ED25519 API.jsing2022-11-093-45/+40
| | | | | | | | | | | BoringSSL implemented a compound private key, which includes a copy of the public key as a performance optimisation for signing. However, this does not readily match with how EVP works, makes the ED25519 API inconsistent with the X25519 API, diverges from th RFC and does not align with the OpenSSL API. Instead, the caller can readily compute the public key and pass this in to the signing process. ok tb@

* Inline use of bn_is_prime_bpsw()tb2022-11-091-24/+20
| | | | | | | | | Instead of using the BN_is_prime_fasttime_ex() API, use a direct call to bn_is_prime_bpsw(). This increases readability and simplifies error handling. Also put a division by two to the natural place now that we no longer need to do Miller-Rabin rounds. ok beck jsing

* Refactor/split ED25519_keypair.jsing2022-11-082-16/+24
| | | | | | This brings in ED25519_keypair_from_seed() from BoringSSL commit c034e2d3ce16, which ED25519_keypair then wraps. This reduces differences between us and BoringSSL.

* Replace the old OpenSSL julian date stuff with BoringSSL'sbeck2022-11-087-326/+289
| | | | | | | | | | | | OpenSSL dealt with time conversion using a classical julian day scheme. BoringSSL got rid of it and uses only a julian style calculation for seconds since the POSIX time epoch. This changes libressl to use the seconds calculation exculusively instead of a mix of the julian day based conversions and the system time conversions to and from time_t to tm. ok tb@ jsing@

* Document that OPENSSL_free() is required in some circumstancestb2022-11-061-2/+6

* Initial parsing of the NewSessionTicket messagetb2022-10-201-2/+103
| | | | | | | | | | | | | | | | | | | | TLSv1.3 introduces a New Session Ticket post-handshake handshake message that allows a unique association between a ticket value and a pre-shared key derived from the resumption master secret. Servers may send this message arbitrarily often at any time after receiving the client's Finished message. Implement tls13_new_session_ticket_recv() which parses the contents of the NewSessionTicket message into a fresh session derived from the current session so as to avoid modifying sessions that are already in the session cache. This uses tls13_new_session_ticket_recv() in tls13_phh_received_cb(). We currently rely on the general rate limiting of 100 PHH messages per connection and hour to avoid problems from connecting to a misbehaving or malicious server. ok jsing
