- Add ->retry_token and ->retry_token_len new quic_conn struct members to store
the retry tokens. These objects are allocated by quic_rx_packet_parse() and
released by quic_conn_release().
- Add <pool_head_quic_retry_token> new pool for these tokens.
- Implement quic_retry_packet_check() to check the integrity tag of these tokens
upon RETRY packets receipt. quic_tls_generate_retry_integrity_tag() is called
by this new function. It has been modified to pass the address where the tag
must be generated
- Add <resend> new parameter to quic_pktns_discard(). This function is called
to discard the packet number spaces where the already TX packets and frames are
attached to. <resend> allows the caller to prevent this function to release
the in flight TX packets/frames. The frames are requeued to be resent.
- Modify quic_rx_pkt_parse() to handle the RETRY packets. What must be done upon
such packets receipt is:
- store the retry token,
- store the new peer SCID as the DCID of the connection. Note that the peer will
modify again its SCID. This is why this SCID is also stored as the ODCID
which must be matched with the peer retry_source_connection_id transport parameter,
- discard the Initial packet number space without flagging it as discarded and
prevent retransmissions calling qc_set_timer(),
- modify the TLS cryptographic cipher contexts (RX/TX),
- wakeup the I/O handler to send new Initial packets asap.
- Modify quic_transport_param_decode() to handle the retry_source_connection_id
transport parameter as a QUIC client. Then its caller is modified to
check this transport parameter matches with the SCID sent by the peer with
the RETRY packet.
HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
Please refer to the following files depending on what you're looking for:
- INSTALL for instructions on how to build and install HAProxy
- BRANCHES to understand the project's life cycle and what version to use
- LICENSE for the project's license
- CONTRIBUTING for the process to follow to submit contributions
The more detailed documentation is located into the doc/ directory:
- doc/intro.txt for a quick introduction on HAProxy
- doc/configuration.txt for the configuration's reference manual
- doc/lua.txt for the Lua's reference manual
- doc/SPOE.txt for how to use the SPOE engine
- doc/network-namespaces.txt for how to use network namespaces under Linux
- doc/management.txt for the management guide
- doc/regression-testing.txt for how to use the regression testing suite
- doc/peers.txt for the peers protocol reference
- doc/coding-style.txt for how to adopt HAProxy's coding style
- doc/internals for developer-specific documentation (not all up to date)
