tankdriver, I think the address in use error may be a red herring, as
thats what happens if you rapidly shutdown and start back up a listening
socket without using the SO_REUSEADDR socket option. dnsmasq is
basically saying that it can't listen because there may be existing
half-closed sockets on the port it wants to listen on.

That said, it needs to be investigated in both network manager and
dnsmasq, so marking as Medium importance in both.

** Changed in: dnsmasq (Ubuntu)

Title:
  Creating hotspot leads to endless connect/disconnect loop

Status in “dnsmasq” package in Ubuntu:
  New
Status in “network-manager” package in Ubuntu:
  New

Bug description:
  - Create Hotspot via "System Settings > Network > Wireless > Hotspot" or manually in the network-manager
  - What I expected:
  * Hotspot is created, clients can use internet connection
  - What happened instead:
  * The new connection connects and disconnects after a second, when "autoconnect" is enabled, this happens very fast in a endless loop.

  I think this error message in the log causes the failure:
  > dnsmasq[5213]: failed to create listening socket for 10.42.43.1: Address already in use
  > dnsmasq[5213]: FAILED to start up
