[libvirt] [PATCH v3 0/9] Series on passing FDs to daemon

[Martin Kletzander]

This started as a fix for virsh 20s timeout of waiting for session
daemon that failed to start:

http://www.redhat.com/archives/libvir-list/2013-April/msg01351.html

Then there was a idea that we can pass some FDs around:

http://www.redhat.com/archives/libvir-list/2013-April/msg01356.html

So we did:

https://www.redhat.com/archives/libvir-list/2014-July/msg00841.html

And now we are even able to start with socket-activation with systemd;
see patch 9/9.

Martin Kletzander (9):
  util: abstract parsing of passed FDs into virGetListenFDs()
  remote: create virNetServerServiceNewFDOrUNIX() wrapper
  rpc: set listen backlog on FDs as well as on other sockets
  daemon: support passing FDs from the calling process
  cfg.mk: allow integers to be assigned a value computed with i|j|k
  tests: support dynamic prefixes in commandtest
  util: add virCommandPassListenFDs() function
  rpc: pass listen FD to the daemon being started
  daemon: use socket activation with systemd
