Package: iproute2
Version: 3.16.0-2
Severity: important
Dear Maintainer,
I was using iproute2 3.15.0-2~bpo70+1 on a stable wheezy.
My network card in using igb driver with VF enable, e.g igb.max_vfs=2
After upgrading to 3.16.0-2~bpo70+1, I have now a segfault while doing a
usual `ip link show dev eth1`.
Disabling VFS make the segafult disappear.
Here is the gdb trace even if it does not contain much info.
The segfault occurs when at the VF step.
(gdb) r link show dev eth1
Starting program: /sbin/ip link show dev eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP mode
DEFAULT group default qlen 10000
link/ether 00:26:6c:ff:b5:c1 brd ff:ff:ff:ff:ff:ff
Program received signal SIGSEGV, Segmentation fault.
0x0000000000408e09 in print_linkinfo ()
(gdb) bt
#0 0x0000000000408e09 in print_linkinfo ()
#1 0x000000000041a231 in iplink_get ()
#2 0x000000000040a93e in ?? ()
#3 0x000000000041a2da in do_iplink ()
#4 0x0000000000407124 in _start ()
The expected output is for example:
# ip link show dev eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP mode
DEFAULT group default qlen 10000
link/ether 00:26:6c:ff:b3:8d brd ff:ff:ff:ff:ff:ff
vf 0 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 1 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
I'm using my own kernel build, a stable v3.14.x
