Description Alexandre Oliva 2003-10-25 21:02:08 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031023

Description of problem:
If a cipe interface is configured to come up at boot time, but the network
interface that provides the default route fails to be brought up on boot (e.g.,
unplugged laptop or failed ppp0 authentication with ISP), the boot will fail, in
that bringing up the cipe interface will never complete, and the only way out of
this is a reboot, either after connecting the computer to a network, or in
single-user mode, disabling the ONBOOT configuration of the cipe channels, then
letting it complete the boot.

Ideally, bringing up the cipe channel should time out just like other network

It seems to be a race condition in ciped.  It clone()s, changes some signal
masks, then pause()s.  Within strace, the cloned process gets control only after
pause(), but I guess without strace, it gets control first, and exit()s before
the parent blocks SIG_CHLD to pause(), so it handles the signal, then blocks it
and pause()s forever.  More details in bug 103516, the original, FC version of
this bug report.

How reproducible:

Steps to Reproduce:
1.Set up a cipe channel configured to come up at boot time
2.Unplug the host from the network
3.Reboot it

Actual Results:  It will fail to bring eth0 up, and then bringing up of the cipe
channel will never complete

Expected Results:  It should time out in a few seconds
