A stream is considered as remotely closed once we have received all the
data with the FIN bit set.
The condition to close the stream was wrong. In particular, if we
receive an empty STREAM frame with FIN bit set, this would have close
the stream even if we do not have yet received all the data. The
condition is now adjusted to ensure that Rx buffer contains all the data
up to the stream final size.
In most cases, this bug is harmless. However, if compiled with
DEBUG_STRICT=2, a BUG_ON_HOT crash would have been triggered if close is
done too early. This was most notably the case sometimes on interop test
suite with quinn or kwik clients. This can also be artificially
reproduced by simulating reception of an empty STREAM frame with FIN bit
set in qc_handle_strm_frm() :
+ if (strm_frm->fin) {
+ qcc_recv(qc->qcc, strm_frm->id, 0,
+ strm_frm->len, strm_frm->fin,
+ (char *)strm_frm->data);
+ }
ret = qcc_recv(qc->qcc, strm_frm->id, strm_frm->len,
strm_frm->offset.key, strm_frm->fin,
(char *)strm_frm->data);
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)
