2012-04-13caif: set traffic class for caif packetsDmitry Tarnyagin
Set traffic class for CAIF packets, based on socket priority, CAIF protocol type, or type of message. Traffic class mapping for different packet types: - control: TC_PRIO_CONTROL; - flow control: TC_PRIO_CONTROL; - at: TC_PRIO_CONTROL; - rfm: TC_PRIO_INTERACTIVE_BULK; - other sockets: equals to socket's TC; - network data: no change.

2011-08-28caif: Remove OOM messages, use kzallocJoe Perches
Remove per site OOM messages because they duplicate the generic mm subsystem OOM message. Use kzalloc instead of kmalloc/memset when next to the OOM message removals.

2011-05-15caif: Handle dev_queue_xmit errors.sjur.brandeland@stericsson.com
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 <sjur.brandeland@stericsson.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-09-06net/caif: Use pr_fmtJoe Perches
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. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-05-17net/caif: Use kzallocJulia Lawall
Use kzalloc rather than the combination of kmalloc and memset. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,size,flags; statement S; @@ -x = kmalloc(size,flags); +x = kzalloc(size,flags); if (x == NULL) S -memset(x, 0, size); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Sjur Brændeland <sjur.brandeland@stericsson.com> Signed-off-by: David S.

2010-04-28caif: Disconnect without waiting for responseSjur Braendeland
Changes: o Function cfcnfg_disconn_adapt_layer is changed to do asynchronous disconnect, not waiting for any response from the modem. Due to this the function cfcnfg_linkdestroy_rsp does nothing anymore. o Because disconnect may take down a connection before a connect response is received the function cfcnfg_linkup_rsp is checking if the client is still waiting for the response, if not a disconnect request is sent to the modem. o cfctrl is no longer keeping track of pending disconnect requests. o Added function cfctrl_cancel_req, which is used for deleting a pending connect request if disconnect is done before connect response is received. o Removed unused function cfctrl_insert_req2 o Added better handling of connect reject from modem.
