Description Sid Boyce 2014-02-04 21:32:29 UTC

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0

It's been a dog configuring the network by hand, bridge br0 does not work so I had to configure eth0.

Reproducible: Always

Steps to Reproduce:
1.Reboot system
2.
3.
Actual Results:  
Network not configured.

Expected Results:  
Network should be configured.

I tried configuring br0 by hand and it doesn't work.
I used "systemctl disable wickedd.service" and "systemctl disable wicked.service" to get around the segmentation faults.
I had to use ifconfig to configure eth0 and use "route add default gw".
yast2 network also does not deliver a working setup.
Basically I am clueless as to what is happening.
NetworkManager is not running.

Comment 1 Olaf Hering 2014-02-04 22:21:36 UTC

The segfault is likely in one of the string functions. Would be nice if a core dump is written per default. Maybe we have to hack around it by calling
sh -c 'ulimit -c unlimited ; $binary' in the service files?

Its proably not fixed in git, but in any case, please add this repo:
zypper ar -c -f -G -K \
 http://download.opensuse.org/repositories/network:/wicked:/master/openSUSE_Factory/ \
wicked_master
zyper -v -v dup -l -r wicked_master

Please also post your config: 
head /etc/sysconfig/network/ifcfg-*

Thanks.


......
Google found LimitCORE=infinity as additional setting for the
/usr/lib/systemd/system/wicked*.service files. 
I think /proc/sys/kernel/core_pattern has to be adjusted to this:
echo "/tmp/core.%e.%p.%t" > /proc/sys/kernel/core_pattern

Comment 3 Olaf Hering 2014-02-05 10:48:06 UTC

I noticed that ulimit is already set by wicked service files. A /core file should be there already. Please run this command and post output:

gdb --readnow --core=/core -ex bt -ex q

Comment 5 Sid Boyce 2014-02-05 12:32:50 UTC

I have not rebooted since upgrading from the new repo advised in Comment 1.
I shall probably be rebooting another box with the same problems later today.

Please try either
zypper in -C "debuginfo(build-id)=52c8bf747f016ea5488cadaf6fb0f3ac80400a67"

or 

zypper -v -v in {glibc,wicked}-debug{source,info} 

Then run the gdb command again, it should be able to resolve the locations

Comment 9 Olaf Hering 2014-02-05 16:33:59 UTC

so even after installing the debuginfo packages gdb can not resolve the backtrace? Thats weird. I think its best to dup to the wicked repo and try again.

I could not get networking to work with "ifconfig br0 192.168.10.10.up", "route add default gw 192.168.10.103"
I had to configure the interfaces separately.

Networking now automatically configured except for the wlan.

One other problem is with setting up bridge br0 using enp5s6.
The bridge is set up and configured but does not work.
route -n and /etc/resolv.conf are all good.

Comment 12 Olaf Hering 2014-02-11 17:16:00 UTC

- good to know the sefault is gone.
- ifcfg-br0 has STP enabled. This causes delays, per specification.
  please remove it and try again. If it persists, open a separate bug.
- ifcfg-wlp0s22f2 lacks the ESSID, it is mandatory.
  If it persists, open a separate bug.

thanks for testing!

Comment 13 Marius Tomaschewski 2014-02-11 17:55:47 UTC

A (cleaned up a bit) config which should work:

when not, please open separate bug report.

Comment 14 Marius Tomaschewski 2014-02-11 18:03:30 UTC

I currently see 2 bugs:

1)
STP='on' we have to fix / adjust the timeouts dynamically when it is used

2)
WIRELESS: it starts and works for me but "wicked ifstatus wlp0s29u1u7"
reports "device-not-started"

Would you be so kind to confirm / open bug reports for these issues?

Comment 15 Sid Boyce 2014-02-11 20:57:10 UTC

Bug 863371 submitted.

Comment 16 Marius Tomaschewski 2014-02-12 07:26:40 UTC

Thanks!

I'm reopening this bug, because I see SEGV in Bug 863371:

"[...]
tindog:/home/lancelot # systemctl status wickedd.service
wickedd.service - wicked network management service daemon
   Loaded: loaded (/usr/lib/systemd/system/wickedd.service; enabled)

[...]"

Would you provide a "rpm -qa | grep wicked" please? And ensure the versions
of libwicked0 and wicked match?

(See https://github.com/openSUSE/wicked/issues/145. We didn't released
 and increased the library version marking it incompatible yet, so you
 always need an exact version match)

zypper in -f -r wicked_master libwicked0 wicked wicked-service libwicked0-debuginfo wicked-debuginfo wicked-debugsource

systemctl restart wickedd
wicked --debug most ifup all

When a SEGV happens, please provide the backtrace output ("gdb --readnow --core=/core -ex bt -ex q" to see which binary dumped core, then again
with additional parameter "/path/to/binary").

Comment 17 Marius Tomaschewski 2014-02-21 11:05:03 UTC

OK, the SEGV is be fixed now, see bug 863371 comment 22.
