Package: initramfs-tools
Version: 0.113
Severity: normal
Dearest Maintainer,
The configure_networking() function in scripts/functions fails
to parse an ip= kernel option if it has more than one parameter
following the device name. For example:
ip=client-ip:server-ip:gw-ip:netmask:hostname:device:autoconf
works just fine, however,
ip=client-ip:server-ip:gw-ip:netmask:hostname:device:autoconf:dns0:dns1
does not, and that happens to be the format described in
https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt
A one character change to configure_networking() will make it immune to
any number of parameters following the device name:

# grab device entry from ip option
NEW_DEVICE=${IP#*:*:*:*:*:*}
if [ ${NEW_DEVICE} != ${IP} ]; then
- NEW_DEVICE=${NEW_DEVICE%:*}

else
# wrong parse, possibly only a partial string
NEW_DEVICE=
In other words: remove the *longest* suffix beginning with :, rather
than the shortest.
