Ido Schimmel cd4d7263d5 genetlink: Use internal flags for multicast groups ... As explained in commit e03781879a ("drop_monitor: Require 'CAP_SYS_ADMIN' when joining "events" group"), the "flags" field in the multicast group structure reuses uAPI flags despite the field not being exposed to user space. This makes it impossible to extend its use without adding new uAPI flags, which is inappropriate for internal kernel checks. Solve this by adding internal flags (i.e., "GENL_MCAST_*") and convert the existing users to use them instead of the uAPI flags. Tested using the reproducers in commit 44ec98ea5e ("psample: Require 'CAP_NET_ADMIN' when joining "packets" group") and commit e03781879a ("drop_monitor: Require 'CAP_SYS_ADMIN' when joining "events" group"). No functional changes intended.
