caif: Bugfix double kfree_skb upon xmit failure

SKB is freed twice upon send error. The Network stack consumes SKB even
when it returns error code.

caif: Fixes freeze on Link layer removal.

2011-05-23T00:11:47+00:00

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.

2011-05-15T21:45:56+00:00

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.

caif: Handle dev_queue_xmit errors.

2011-05-15T21:45:56+00:00

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.

caif: prepare support for namespaces

2011-05-15T21:45:55+00:00

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.

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

2011-05-15T21:45:55+00:00

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.

caif: Don't resend if dev_queue_xmit fails.

2011-04-11T22:08:48+00:00

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.
