llc: Fix missing msg_namelen update in llc_ui_recvmsg()

2013-05-01T16:46:02Z

[ Upstream commit c77a4b9cffb6215a15196ec499490d116dfad181 ] For stream sockets the code misses to update the msg_namelen member to 0 and therefore makes net/socket.c leak the local, uninitialized sockaddr_storage variable to userland -- 128 bytes of kernel stack memory. The msg_namelen update is also missing for datagram sockets in case the socket is shutting down during receive. Fix both issues by setting msg_namelen to 0 early. It will be updated later if we're going to fill the msg_name member. Signed-off-by: Mathias Krause Cc: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

net: Allow userns root to control llc, netfilter, netlink, packet, and xfrm

2012-11-19T01:32:45Z

Allow an unpriviled user who has created a user namespace, and then created a network namespace to effectively use the new network namespace, by reducing capable(CAP_NET_ADMIN) and capable(CAP_NET_RAW) calls to be ns_capable(net->user_ns, CAP_NET_ADMIN), or capable(net->user_ns, CAP_NET_RAW) calls. Allow creation of af_key sockets. Allow creation of llc sockets. Allow creation of af_packet sockets. Allow sending xfrm netlink control messages. Allow binding to netlink multicast groups. Allow sending to netlink multicast groups. Allow adding and dropping netlink multicast groups. Allow sending to all netlink multicast groups and port ids. Allow reading the netfilter SO_IP_SET socket option. Allow sending netfilter netlink messages. Allow setting and getting ip_vs netfilter socket options. Signed-off-by: "Eric W.

llc2: Remove explicit indexing of state action arrays

2012-09-17T17:04:19Z

These arrays are accessed by iteration in llc_exec_station_trans_actions(). There must not be any zero-filled gaps in them, so the explicit indices are pointless. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

llc2: Remove the station send queue

2012-09-17T17:04:18Z

We only ever put one skb on the send queue, and then immediately send it. Remove the queue and call dev_queue_xmit() directly. This leaves struct llc_station empty, so remove that as well. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

llc2: Collapse the station event receive path

2012-09-17T17:04:18Z

We only ever put one skb on the event queue, and then immediately process it. Remove the queue and fold together the related functions, removing several blatantly false comments. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

llc2: Remove dead code for state machine

2012-09-17T17:04:18Z

The initial state is UP and there is no way to enter the other states as the required event type is never generated. Delete all states, event types, and other dead code. The only thing left is handling of the XID and TEST commands. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

llc2: Remove pointless indirection through llc_stat_state_trans_end
