747be414e2 Release 2.8.4
- [HTTP3] Verify number of bytes in incoming DATA frames against

  ACK frames.
- IETF QUIC: use RTT estimate in ack timeout calculation.

  the same.

  consistent performance.

a137764bf2 Release 2.7.2

  that we use loss chains.

5c957fdcf6 Add explicit include for musl (#91) 2019-12-05 15:48:06 -05:00
Dmitri Tikhonov
936463fe29 Release 2.7.1
- [BUGFIX] client: don't call ignore_init() in middle of batch send.
  ignore_init() makes an assumption that the send controller has access
  to all outgoing packets.  This change wraps a few IETF full connection
  methods to delay calling ignore_init() until the engine returns all
  outgoing packets that were batched.
- [BUGFIX] set errno to EAGAIN if sendmmsg() can't send all of them.
  This needs to be done because the value of errno may be lost on
  some platforms.
- [BUGFIX] Typo that set all bits in sm_qflags lead to crashes.
- [BUGFIX] Do not cancel header block processing after failure, as
  QPACK releases the reference in that case.
- [CLEANUP] IETF encrypt: replace assert(0) with a warning.
- Several small improvements to the test server.

Dmitri Tikhonov
7ee4152504 Release 2.7.0
- [API, FEATURE] Close connection immediately when ea_packets_out()
  fails with errno != EAGAIN.  The API change is that errno is now
  examined.  Make sure to set it if using something other than
  sendmsg() to send packets.
- [CLEANUP] Immediate close logic in IETF full conn.
- [CLEANUP] Fix bogus warning about uninitialized `pair' variable.

2019-11-11 14:05:54 -05:00
Dmitri Tikhonov
84dbbb75d5 Release 2.6.1
