[libvirt] [PATCHv3 0/6] Fix memory corruption/crash in the connection close callback

[Peter Krempa]

This series fixes the crash resulting from a race condition in the connection
close callback. To observe the crash apply the first patch only. To verify that
the patchset fixes the crash please apply all but 2/6 and verify using virsh.
2/6 fixes the crash in a redundant way in case the close callback is used. In
the case it isn't 2/6 itself can't fix the issue.

For a better explanation of this problem please see the description in 6/6.

Peter Krempa (4):
  DO NOT APPLY UPSTREAM: Close callback race corruption crash
    reproducer.
  virsh: Move cmdConnect from virsh-host.c to virsh.c
  virsh: Register and unregister the close callback also in cmdConnect
  rpc: Fix connection close callback race condition and memory
    corruption/crash

Viktor Mihajlovski (2):
  libvirt: Increase connection reference count for callbacks
  virsh: Unregister the connection close notifier upon termination
