[User-mode-linux-user] problem with um_eth_net_util

[Laurent B. <Lau...@iu...>]

Hi,

I was trying various virtual network settings and the um_eth_net_util
deamon crashed (sorry, no backtrace).

Then uml kernel started to print an endless number of messages:

  Failed to forward 15 to pid 16049, errno = 9

When I restarted the deamon, uml printed the following:

  Registering fd 15 twice
  Irqs : 4, 4
  Ids : 0x5005cc00, 0x5005cc00

Perhaps it would be a good idea to improve the error recovery of uml.
When the um_eth_net_util deamon stops, it could print "connection with
um_eth_net_util deamon lost" and behave as if one had pulled the RJ45
plug.
