commit 750c491df7fb5c259a915fd727cec9fdce899186 Author: Sławek Kapłoński <[email protected]> Date: Sun Jan 22 08:20:32 2017 +0000 Handle attempt to enable br_netfilter in namespace When the process is using the IptablesFirewall driver and is running in namespaces, there is no /proc/sys/net/bridge in the namespace available and enable of netfilter for bridge fails with stacktrace in logs. This patch handles the exception thrown during a failed attempted to retrieve net.bridge variable names and prints an info message in agent logs instead of printing a stacktrace. Change-Id: I1ff6cedbf933ac54ef4bbf1d44fc8f57f68d57fc Closes-bug: 1658343 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1658343 Title: Bridge netfilter can't be enabled if process is running in namespace Status in neutron: Fix Released Bug description: If agent (like Linuxbridge L2 agent) is using iptables firewall driver, it tries to enable netfilter for bridges. In case when agent is running in namespace (like is for example in fullstack tests), /proc/sys/net/bridge is not available in namespace and there is "ugly" traceback in agent's logs. You can see it e.g. on http://logs.openstack.org/32/417532/5/check/gate-neutron-dsvm- fullstack-ubuntu-xenial/2842dcd/logs/dsvm-fullstack- logs/TestSecurityGroupsSameNetwork.test_tcp_securitygroup_linuxbridge- iptables_/neutron-linuxbridge-agent--2017-01-18-- 15-23-07-339346.txt.gz#_2017-01-18_15_23_17_436 IMO it could be good to check if /proc/sys/net/bridge exists and print some warning that it's not available so operator should manually ensure that those options are enabled on host if security groups should works there.
