Bug 383339 – app-admin/syslog-ng-3.2.4: init script fails to start with ethernet bonding

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Remco Overdijk 2011-09-17 12:05:10 UTC]

/etc/init.d/syslog-ng checks if any configuration in syslog-ng.conf requires a network connection. 
On my system it does, because I am receiving remote Cisco logs, so syslog-ng will "need net".

This used to work fine with a regular net setup (net.eth0 and net.eth1). 
Now I have an ethernet bonding setup however, so net.eth0 and net.eth1 have been removed an have been replaced by net.bond0.

This causes syslog-ng to fail it's start during boot.
(See: https://rem.co/syslog-ng-fail.jpg for the actual result)
I can't image this being due to an actual problem with net.bond0, as you can see in the screenshot, it starts correctly directly after.

I have tried to change the init script, modifying the "need" parameter and adding an "after" parameter, but I'm too big a n00b to make it work.

This may be due to the fact that a bonding device takes longer than an actual eth to come up, so maybe it's marked as failed incorrectly

excerpt from kern.log:
Sep 17 13:47:19 gd kernel: ADDRCONF(NETDEV_UP): bond0: link is not ready
Sep 17 13:47:19 gd kernel: ADDRCONF(NETDEV_UP): bond0: link is not ready
Sep 17 13:47:19 gd kernel: bonding: bond0: Adding slave eth0.
Sep 17 13:47:19 gd kernel: bonding: bond0: enslaving eth0 as an active interface with a down link.
Sep 17 13:47:19 gd kernel: e1000: eth0 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX
Sep 17 13:47:19 gd kernel: bonding: bond0: Adding slave eth1.
Sep 17 13:47:19 gd kernel: bonding: bond0: enslaving eth1 as an active interface with a down link.
Sep 17 13:47:19 gd kernel: e1000: eth1 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX
Sep 17 13:47:19 gd kernel: bonding: bond0: link status definitely up for interface eth0, 100 Mbps full duplex.
Sep 17 13:47:19 gd kernel: bonding: bond0: link status definitely up for interface eth1, 100 Mbps full duplex.
Sep 17 13:47:19 gd kernel: ADDRCONF(NETDEV_CHANGE): bond0: link becomes ready


After the boot has completed, '/etc/init.d/syslog-ng start' works fine once again.

Reproducible: Always

Steps to Reproduce:
1. Configure system for ethernet bonding
2. Remove normal net.* symlinks from /etc/init.d
3. Reboot
Actual Results:  
* ERROR: cannot start syslog-ng as net.bond0 would not start

Expected Results:  
* Starting syslog-ng                        [ ok ]

Doesn't sound like a syslog-ng problem so much as the service getting started too soon.

[Comment 2 Remco Overdijk 2011-09-19 10:38:08 UTC]

Agree, syslog-ng as a program works fine, but being started too soon causes the error. 
After some more research I actually found out that syslog-ng being pulled early is due to the fact that ip6tables is in the default runlevel. (Which would be the issue described in https://bugs.gentoo.org/show_bug.cgi?id=228973 instead of a separate bug).
The fact remains however that this configuration used to work without ethernet bonding, but fails after enabling. Could it be filed under 'dumb luck' that the original configuration worked, looking at 228973? 

In the meantime I have removed ip6tables from the runlevel as shorewall is starting to provide firewall, which also sets ip6tables state during init. As shorewall doesn't need the logger, syslog-ng now starts after net, which eliminates the problem.

[Comment 3 Mr. Bones. (RETIRED) 2013-05-10 21:40:11 UTC]

try it with syslog-ng-3.4.1 please

[Comment 4 Mr. Bones. (RETIRED) 2013-08-13 21:45:35 UTC]

use syslog-ng 3.4.x
