- [BUGFIX] Fix double-free when emptying a packet number space.
- [BUGFIX] http_server: fix md5sum handler: handle EOF correctly.
- [BUGFIX] Use random values in bits 4 and 5 of the first byte of
verneg packets (regression introduced in 2.5.0).
- [OPTIMIZATION] Don't compile in expensive attq checks by default.
- [OPTIMIZATION] http_server: compile regexes only once.
- [API] lsquic_engine_connect() can now be passed QUIC version to use.
- [OPTIMIZATION] Queue opportunistic ACKs if there is data to be sent.
- [BUGFIX] Don't evict streams from priority iterator if there is
only one queue.
- [OPTIMIZATION, BUGFIX] Several other optimizations and bug fixes.
- Use ls-qpack v0.10.7.
- [BUGFIX] IETF QUIC server: fix uninitialized variable use.
- [BUGFIX] make sure TLSv1.3 is not disabled in SSL object.
- [BUGFIX] Use issuer name and serial number to cache certs (SKID
values are not unique).
- [BUGFIX] Always set the idle alarm in IETF connection so that it
can time out.
- Add echo client and server to the distibution.
- Add MD5 client and server to the distibution.
- Fix http_client: check command-line arguments better, prevent crash.
- Fix IETF conn: can_write_ack() should only care about APP PNS.
- Client: delay stream creation until handshake succeds.
- Reset HTTP stream whose write end is closed prematurely.
- Fix tickable(): mirror behavior of tick() wrt buffered packets.
- Log reason why engine is tickable.
- Minor code cleanup and logging improvements.
- Server and client programs: include library version (e.g. 2.4.6)
into `server' and `user-agent' headers.
- [OPTIMIZATION]: flush encoder stream only when necessary.
- [BUGFIX] Use ls-qpack v0.10.2 for new API -- and for a bug fix.
- [BUGFIX] Typo in IETF conn SETTINGS writer.
- Use latest BoringSSL.
- [API] Add lsquic_alpn2ver() to aid parsing Alt-Svc header.
- [BUGFIX] NULL dereference when H3 frame header would be split.
- [BUGFIX] Do not close fixed-size H3 frame prematurely.
- [BUGFIX] Allow PING frames in IETF mini conn.
- [BUGFIX] Mini conns: don't send any packets after receiving
CONNECTION_CLOSE.
- [BUGFIX] Client migration: reserve slot for DCID from transport params.
- [BUGFIX] Allow max_early_data_size=0 -- early_data might not be there.
- [BUGFIX] Use an invalid stream number to reset BPT cache (zero is now a
valid stream number).
- [SPEC] Use FINAL_SIZE_ERROR when FIN mismatch is detected.
- [OPTIMIZATION] Closed connection only gets one chance to send packets.
- [OPTIMIZATION] Flush headers stream before packetizing stream data.
- [OPTIMIZATION] process QPACK encoder STREAM frames immediately.
- Update ls-qpack to v0.10.1.
- Add GQUIC versions to the list of h3 ALPNs for Alt-Svc header.
For example, h3-Q043. Chrome will switch to using this format at
some point in the future.
- [BUGFIX] Send correct value in max_streams_uni transport param
- [SPEC] Abort IETF QUIC connection if max_early_data_size is not set
to 0xFFFFFFFF
- [BUGFIX] H3 framing: fix zero-byte write when space is available
- [BUGFIX] Don't send STREAM frame when incoming unidirectgional stream
is closed
- [BUGFIX] Cancel all pending writes by stream reset by a GOAWAY
- [BUGFIX] Fix use-after-free in IETF full conn
- [OPTIMIZATION] Wait for session tickets for two seconds and then drop
SSL object and crypto streams.
- [BUGFIX] If FIN or RST not received, don't delay stream destruction.
- [OPTIMIZATION] Speed up HPACK encoder by using same hash value to
search static and dynamic tables.
- [BUGFIX] Ensure that Largest Observed does not decrease in ACKs we
send. ACK frames placed in packets in buffered queues (optimization
introduced in 1.17.15) can be preceded by an ACK frame generated later.
In this case, the older ACK frame should not be sent out, as Chromium-
based servers flags decrease in the ACK frame's Largest Observed value
as an error.
- [BUGFIX] Use correct public key from PUBS based on KEXS index.
- [BUGFIX] Check flags before dispatching writes, avoiding assert.
- [BUGFIX] Set :scheme to "https" (instead of "HTTP").
- [BUGFIX] Check buffer bounds when looking up version in 0-RTT blob.
- [BUGFIX] http_client: don't fetch 0-rtt info if handshake failed.
- Log number of pacer calls at DEBUG, rather than NOTICE, level.
- [BUGFIX] Q044: don't encode packet number in 6 bytes. Six-byte
packet number encoding does not exist in Q044. This fixes a
regression introduced in '[BUGFIX] Buffered packets can contain
ACK frames' -- we need to keep QUIC version in mind when selecting
the longest possible packet number encoding used for the buffered
packet that carries the ACK.
- [BUGFIX] Do not increase CWND when timeout occurs.
- http_client: support setting handshake timeout on command line.
Use -o handshake_to=timeout.
- http_client: use -k to connect UDP socket to pick up ICMP errors.
- http_client: allow pathless mode, when only handshake is performed
without issuing any requests. This can be done by simply not
specifying a -p flag on the command line.
