Message-id: <1266328017-28406-1-git-send-email-sjur.brandeland@stericsson.com> Date: Tue, 16 Feb 2010 14:46:45 +0100 From: sjur.brandeland@...ricsson.com To: davem@...emloft.net, netdev@...r.kernel.org Cc: stefano.babic@...ic.homelinux.org, randy.dunlap@...cle.com, daniel.martensson@...ricsson.com, kaber@...sh.net, marcel@...tmann.org, Sjur Braendeland <sjur.brandeland@...ricsson.com> Subject: [PATCH net-next-2.6 v2 00/12] net-caif: introducing CAIF protocol stack From: Sjur Braendeland <sjur.brandeland@...ricsson.com> This patch-set introduces the CAIF protocol Stack. The "Communication CPU to Application CPU Interface" (CAIF) is a packet based connection-oriented MUX protocol developed by ST-Ericsson for use with its modems. CHANGE LOG: Based on review comment from Marcel Holtmann, Patrick McHardy, and Randy Dunlap on the previous patch set submitted the 20th Jan the following changes has been done: - Removed "CAIF Kernel Client API for CAIF". - In CAIF Net device: removed IOCTL management. - In Socket Interface, removed socket option CAIFSO_CHANNEL, and replaced it with SO_PRIORITY, SO_BINDTODEVICE and CAIFSO_LINK_SELECT. - In caif_socket.c, implemented most of CAIF socket options. - Moved Caif Core protocol files out of directory 'generic' - Removed glue code cfglue.h, this causes lots of small changes in CAIF core. - Removed linked list code cflst.h, cflist.c this impacts caifmux.c. - Added CAIF debug service cfdbgl.c. - In CAIF Net device, fixed race condition with rtnl when unloading of module. - In Linux-CAIF.txt, minor updates including fixing some spelling mistakes. - In README, added more documentation on CAIF Serial debugging. - In caif_serial.c, the TTY is no longer opened from kernel, but the line discipline must be installed from user space utility. - In caif_serial.c, added debugfs entries for last received and transmitted messages and status information. - Attempting to conform to kernel-doc formatting conventions. OVERVIEW: * CAIF provides a socket interface which can be used to open virtual AT channels, create and configure GPRS Data connections. * A CAIF Network device is also provided for GPRS access. This interface can be managed with RTNL. * A kernel interface is provided allowing Kernel modules to use CAIF. * A serial link layer layer implemented as a line discipline is currently implemented. Other link interfaces may be contributed at a later stage. RTNL ! ! +------+ +------+ +------+ ! +------+! +------+! +------+! ! ! Sock !! !Kernel!! ! Net !! ! ! API !+ ! API !+ !
