qc_prep_pkts() activates padding when building an Initial packet. This ensures that resulting datagram will always be at least 1.200 bytes, which is mandatory to prevent deadlock over anti-amplication. Prior to padding activation, a check is performed to ensure that output buffer is big enough for a padded datagram. However, this did not take into account previously built packets which would be coalesced in the same datagram. Thus this patch fixes this comparison check. In theory, prior to this patch, in some cases Initial packets could not be built despite a datagram of the proper size. Currently, this probably never happens as Initial packet is always the first encoded in a datagram, thus there is no coalesced packet prior to it. However, there is no hard requirement on this, so it's better to reflect this in the code. This should be backported up to 2.6.
HAProxy

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
