lsquic - API and doc cleanup; minor bug fixes

Published by litespeedtech over 4 years ago

  • [API] Rename "0-RTT" to "session resumption." In IETF QUIC, "0-RTT" always refers to early data, meaning a request that the server can reply to in the very first return flight. A more appropriate name for what we support on the client site is "session resumption," which is standard TLS terminology. Later, when we add support for 0-RTT (early data), we can use the 0-RTT terminology again, this time in proper context.
  • [BUGFIX] Do not set certificate callback if ea_lookup_cert is NULL.
  • [BUGFIX] Make connection tickable when it's marked as closed.
  • [BUGFIX] Fail certificate lookup if SNI is not present in HTTP mode.
  • Several documentation fixes and improvements.
  • Minor code cleanup.

  • [BUGFIX] Don't count scheduled packets as in-flight when pacer is checked on tick.
  • gQUIC: delay calling on_new for pushed stream until headers are available.
  • Allow nested calls to lsquic_engine_connect().
lsquic - Bugfix release: early data regression

Published by litespeedtech over 4 years ago

lsquic - Bugfix release; stash reordered packets

Published by litespeedtech over 4 years ago

  • [OPTIMIZATION] Stash up to two reordered packets in IETF mini conn instead of dropping them.

lsquic - Bug fixes; updated BoringSSL

Published by litespeedtech over 4 years ago

  • [BUGFIX] Log messages when SCID changes.
lsquic - Bug fixes; newer BoringSSL

Published by litespeedtech over 4 years ago

  • [BUGFIX] ID-28: do not use TLS middlebox compatibility mode in ClientHello. This change requires using a newer version of BoringSSL.
  • [BUGFIX] Free connections in Advisory Tick Time Queue in engine dtor.
  • [BUGFIX] IETF QUIC client: narrow migration check to a single path.
  • [BUGFIX] NULL dereference: set function pointers for alarm for path challenges 2 and 3.
  • [BUGFIX] HTTP/3 headers may be followed immediately by trailers.
  • [BUGFIX] Log messages when SCID changes.
lsquic - No-progress timeout; several bug fixes

Published by litespeedtech over 4 years ago

  • [FEATURE] Use "no-progress timeout" after which connection is closed.
  • [BUGFIX] Select new SCID when current SCID is retired.
  • [BUGFIX] Don't warn about dropped Initial packet sequence gaps during mini/full handoff.
  • [BUGFIX] Send correct conn error when HTTP/3 frame is truncated.
  • [BUGFIX] Mini conn: consider amplification when deciding to return TICK_SEND.
  • [BUGFIX] Don't double-count tag length in amplification logic.
  • [BUGFIX] Don't squeeze out lone path challenges.
  • [BUGFIX] Log messages dealing with scheduled packet queue squeezing.
  • [BUGFIX] don't wipe current path if no path challenge responses come back.
  • [BUGFIX] When path is reset, don't lose path_id which is used for logging.
  • Downgrade flow control violations to info log level from warnings.
  • Fix connection cap extra check, avoid checks in nested calls.
  • Fix some unit tests when extra checks are enabled.
  • Use ls-hpack 2.2.1.
  • Turn off unconditional extra checks for IETF clients.
  • Extra checks: don't verify sent size of hello packets. Client changes DCID length and this check will fail.
