haproxy generates for each QUIC connection a set of CID. The peer must reuse them as DCID for its emitted packet. On datagram reception, DCID field serves as identifier to dispatch them on their correct thread. These CIDs are stored in a global CID tree. Access to this data structure must always be protected with CID_LOCK. This commit is a refactoring to regroup all CID tree access in quic_cid module. Several code parts are ajusted : * quic_cid_insert() is extended to check for insertion race-condition. This is useful on quic_conn instantiation. Code where such race cannot happen can use unsafe _quic_cid_insert() instead. * on RETIRE_CONNECTION_ID frame reception, existing quic_cid_delete() function is used. * remove tree lookup from qc_check_dcid(), extracted in the new quic_cmp_cid_conn() function. Ultimately, the latter should be removed as CID lookup could be conducted on quic_conn owned tree without locking. |

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.
