From c383edc42403b0bca31cbaabafd44dd58afb202f Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Tue, 4 Sep 2018 21:53:47 +0200 Subject: rtnetlink: add rtnl_get_net_ns_capable() get_target_net() will be used in follow-up patches in ipv{4,6} codepaths to retrieve network namespaces based on network namespace identifiers. So remove the static declaration and export in the rtnetlink header. Also, rename it to rtnl_get_net_ns_capable() to make it obvious what this function is doing. Export rtnl_get_net_ns_capable() so it can be used when ipv6 is built as a module. Signed-off-by: Christian Brauner Signed-off-by: David S.

The IFA_TARGET_NETNSID property can be used to send a network namespace identifier as part of a request. If a IFA_TARGET_NETNSID property is identified it will be used to retrieve the target network namespace in which the request is to be made.
