Restrict two generic netlink multicast groups - in the "psample" and "NET_DM" families - to be root-only with the appropriate capabilities.
Patch #1 is a dependency of patch #2 which is needed by the actual fixes in patches #3 and #4.
Florian Westphal (1): netlink: don't call ->netlink_bind with table lock held
Ido Schimmel (3): genetlink: add CAP_NET_ADMIN test for multicast bind psample: Require 'CAP_NET_ADMIN' when joining "packets" group drop_monitor: Require 'CAP_SYS_ADMIN' when joining "events" group
