Subject: [PATCH 5.10 0/4] Generic netlink multicast fixes
Date: Mon, 11 Dec 2023 14:37:36 +0200 [thread overview]
Message-ID: <20231211123740.822802-1-idosch@nvidia.com> (raw)
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
