Willy Tarreau 59b5da4873 BUG/MEDIUM: listener: never suspend inherited sockets
It is not acceptable to suspend an inherited socket because we'd kill
its listening state, making it possibly unrecoverable for future
processes. The situation which can trigger this is when there is an
abns socket in a config and an inherited FD on another listener. Upon
soft reload, the abns fails to bind, a SIGTTOU is sent to the old
process which suspends everything, including the inherited FD, then
the new process can bind and tell the old one to quit. Except that the
new FD was not set back to the listen state, which is detected by
listener_accept() which can pause it. It's only upon second reload
that the FD works again.

The solution is to refrain from suspending such FDs since we don't own
them. And the next process will get them right anyway from its config.
For now only TCP and UDP face this issue so it's better to address this
on a protocol basis

No backport is needed, this is related to the new listeners in 2.3.

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
