Package: radvd
Version: 1:1.6-1
Severity: important
Tags: upstream patch ipv6
When starting IPv6 nodes in my network shortly after radvd is started,
radvd sometimes crashes with a segfault. I have traced it to a coding
error in the clear_timer function of timer.c in the radvd source
distribution.
Under some circumstances, clear_timer() in timer.c is called when the
timer_lst argument's prev and next members are NULL. clear_timer tries
to follow these pointers without checking if they are valid or not,
resulting in a segfault. Rather than figuring out why an incorrect
timer_lst structure is being passed in, I have modified the code in the
clear_timer function to check these pointers before following them.
A patch is attached.
