[Bug 1535648] Re: ifquery crashing

2016-02-10 Thread Hadmut Danisch 
typo:  meant ifquery --state   instead of ifstate


Need to do more checks, but seems to be fixed on Ubuntu 16.04, which comes with 
a newer version of ifupdown

[Bug 1535648] Re: ifquery crashing

2016-01-20 Thread Hadmut Danisch 
I've found two problems:


1.) See /lib/systemd/system/ifup-wait-all-auto.service   the line 

  for i in $(ifquery --list --exclude lo --allow auto); do
INTERFACES="$INTERFACES$i "; done;

  There is  a space missing in "$INTERFACES$i "  it concatenates all
device names into one


2.) This ifquery-call just crashes:

# ifquery --state vlan0
Segmentation fault (core dumped)

# ifquery --state lo
Segmentation fault (core dumped)


for some reason it does not crash with eth0

# ifquery --state eth0


So please fix ifquery.

More analysis:

ifstate crashes if /run/network/ifstate is not present.
