caif: Bugfix - XOFF removed channel from caif-mux

2011-06-17T03:59:09+00:00

XOFF was mixed up with DOWN indication, causing causing CAIF channel to be
removed from mux and all incoming traffic to be lost after receiving flow-off.
Fix this by replacing FLOW_OFF with DOWN notification.

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: Use rcu_read_lock in CAIF mux layer.

2011-05-15T21:45:54+00:00

Replace spin_lock with rcu_read_lock when accessing lists to layers
and cache. While packets are in flight rcu_read_lock should not be held,
instead ref-counters are used in combination with RCU.

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.

net/caif: Use pr_fmt

2010-09-07T01:48:43+00:00

This patch standardizes caif message logging prefixes.

Add #define pr_fmt(fmt) KBUILD_MODNAME ":%s(): " fmt, __func__
Add missing "\n"s to some logging messages
Convert pr_warning to pr_warn

This changes the logging message prefix from CAIF: to caif:
for all uses but caif_socket.c and chnl_net.c.  Those now use
their filename without extension.
