modprobe: module br_netfilter not found in modules.dep on CentOS7

[rmohr]

Hi,

Just pulled in weave 1.9.1 via https://git.io/weave-kube on CentOS7

image: weaveworks/weave-kube:1.9.1

The container weave does not come up because it complains about the missing br_netfilter module:

modprobe: module br_netfilter not found in modules.dep

The container is right that the module is not there, because it is built in in the CentOS default kernel:

ls -l /proc/sys/net/bridge
total 0
-rw-r--r--. 1 root root 0 Feb 28 09:31 bridge-nf-call-arptables
-rw-r--r--. 1 root root 0 Feb 28 09:31 bridge-nf-call-ip6tables
-rw-r--r--. 1 root root 0 Feb 28 09:31 bridge-nf-call-iptables
-rw-r--r--. 1 root root 0 Feb 28 10:05 bridge-nf-filter-pppoe-tagged
-rw-r--r--. 1 root root 0 Feb 28 10:05 bridge-nf-filter-vlan-tagged
-rw-r--r--. 1 root root 0 Feb 28 10:05 bridge-nf-pass-vlan-input-dev

It worked with older versions of weave, so maybe there was a recent change which causes this?

Yes there was a recent change; it is the 4th item in the release notes

Apologies that this broke on CentOS; we will need to investigate that.

@rmohr could you provide the output of zgrep CONFIG_BRIDGE_NETFILTER /proc/config.gz?

[rmohr]

@brb, sure:

$ zgrep CONFIG_BRIDGE_NETFILTER /boot/config-`uname -r`
CONFIG_BRIDGE_NETFILTER=y

@rmohr We have released 1.9.2 which fixes the bug: https://github.com/weaveworks/weave/releases/tag/v1.9.2. Could you try it out?

[rmohr]

@brb 1.9.2 came up on my setup without problems and kubenetes network was working 👍 Thanks for fixing this so fast.
