caif: Fix missing msg_namelen update in caif_seqpkt_recvmsg()

2013-05-01T15:56:39Z

[ Upstream commit 2d6fbfe733f35c6b355c216644e08e149c61b271 ] The current code does not fill the msg_name member in case it is set. It also does not set 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. Fix that by simply setting msg_namelen to 0 as obviously nobody cared about caif_seqpkt_recvmsg() not filling the msg_name in case it was set.

caif: Fixes freeze on Link layer removal.

2011-05-23T00:11:47Z

CAIF Socket layer - caif_socket.c: - Plug mem-leak at reconnect. - Always call disconnect to cleanup CAIF stack. - Disconnect will always report success. CAIF configuration layer - cfcnfg.c - Disconnect must dismantle the caif stack correctly - Protect against faulty removals (check on id zero) CAIF mux layer - cfmuxl.c - When inserting new service layer in the MUX remove any old entries with the same ID. - When removing CAIF Link layer, remove the associated service layers before notifying service layers.

caif: Bugfix debugfs directory name must be unique.

2011-05-15T21:45:56Z

Race condition caused debugfs_create_dir() to fail due to duplicate name. Use atomic counter to create unique directory name. net_ratelimit() is introduced to limit debug printouts. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: Handle dev_queue_xmit errors.

2011-05-15T21:45:56Z

Do proper handling of dev_queue_xmit errors in order to avoid double free of skb and leaks in error conditions. In cfctrl pending requests are removed when CAIF Link layer goes down. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: prepare support for namespaces

2011-05-15T21:45:55Z

Use struct net to reference CAIF configuration object instead of static variables. Refactor functions caif_connect_client, caif_disconnect_client and squach files cfcnfg.c and caif_config_utils. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: Protected in-flight packets using dev or sock refcont.

2011-05-15T21:45:55Z

CAIF Socket Layer and ip-interface registers reference counters in CAIF service layer. The functions sock_hold, sock_put and dev_hold, dev_put are used by CAIF Stack to protect from freeing memory while packets are in-flight. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller

caif: Don't resend if dev_queue_xmit fails.

2011-04-11T22:08:48Z

If CAIF Link Layer returns an error, we no longer try to re-build the CAIF packet and resend it. Instead, we simply return any transmission errors to the socket client. Signed-off-by: Sjur Brændeland Signed-off-by: David S. Miller
