It is possible to receive a STOP_SENDING frame for a locally closed stream. This was not properly managed as this would result in a BUG_ON() crash from qcs_idle_open() call under qcc_recv_stop_sending(). Now, STOP_SENDING frames are ignored when received on streams already locally closed. This has two consequences depending on the reason of closure : * if a RESET_STREAM was already emitted and closed the stream, this patch prevents to emit a new RESET_STREAM. This behavior is thus better. * if stream was closed due to all data transmitted, no RESET_STREAM will be built. This is contrary to the RFC 9000 which advice to transmit it, even on "Data Sent" state. However, this is not mandatory so the new behavior is acceptable, even if it could be improved. This crash has been detected on haproxy.org. This can be artifically reproduced by adding the following snippet at the end of qc_send_mux() when doing a request with a small payload response : qcc_recv_stop_sending(qc->qcc, 0, 0); This must be backported up to 2.6. |

The HAProxy documentation has been split into a number of different files for ease of use. 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)
