In general those permission rules are true. However, netlink protocols have the
ability to allow non-root senders and recievers even for those types of
packets. It's up to the subsystem to allow them. Currently, kobject_uevent,
selinux, rtnetlink, and genetlink all allow non-root receivers. None of them
allow non-root senders.
Petr, can you add the following paragraph below the last paragraph in the
"Address Groups" section? It should probably go upstream as well.
Some Linux kernel subsystems may additionally allow other users to send and/or
receive messages. As of Linux 3.0, the NETLINK_KOBJECT_UEVENT, NETLINK_GENERIC,
NETLINK_ROUTE, and NETLINK_SELINUX groups allow other users to receive
messages. No groups allow other users to send messages.
