* Phonet: allocate sock from accept syscall rather than soft IRQRémi Denis-Courmont2011-03-091-1/+0
| | | | | | | | | This moves most of the accept logic to process context like other socket stacks do. Then we can use a few more common socket helpers and simplify a bit. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* Phonet: fix flawed "SYN/ACK" logicRémi Denis-Courmont2011-02-251-0/+1
| | | | | | | | | | | | | | * Do not fail if the peer supports more or less than 3 algorithms. * Ignore unknown congestion control algorithms instead of failing. * Simplify congestion algorithm negotiation (largest is best). * Do not use a static buffer. * Fix off-by-two read overflow. * Avoid extra memory copy (in addition to skb_copy_bits()). The previous code really made no sense. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* Phonet: 'connect' socket implementation for Pipe controllerKumar Sanghvi2010-10-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Based on suggestion by Rémi Denis-Courmont to implement 'connect' for Pipe controller logic, this patch implements 'connect' socket call for the Pipe controller logic. The patch does following:- - Removes setsockopts for PNPIPE_CREATE and PNPIPE_DESTROY - Adds setsockopt for setting the Pipe handle value - Implements connect socket call - Updates the Pipe controller logic User-space should now follow below sequence with Pipe controller:- -socket -bind -setsockopt for PNPIPE_PIPE_HANDLE -connect -setsockopt for PNPIPE_ENCAP_IP -setsockopt for PNPIPE_ENABLE GPRS/3G data has been tested working fine with this.

* Phonet: Implement Pipe Controller to support Nokia Slim ModemsKumar Sanghvi2010-09-271-0/+21
| | | | | | | | | | | | | Phonet stack assumes the presence of Pipe Controller, either in Modem or on Application Processing Engine user-space for the Pipe data. Nokia Slim Modems like WG2.5 used in ST-Ericsson U8500 platform do not implement Pipe controller in them. This patch adds Pipe Controller implemenation to Phonet stack to support Pipe data over Phonet stack for Nokia Slim Modems.

* Phonet: remove dangling pipe if an endpoint is closed earlyRémi Denis-Courmont2010-09-151-0/+5
| | | | | | | | | | | | | | | | Closing a pipe endpoint is not normally allowed by the Phonet pipe, other than as a side after-effect of removing the pipe between two endpoints. But there is no way to prevent Linux userspace processes from being killed or suffering from bugs, so this can still happen. We might as well forcefully close Phonet pipe endpoints then. The cellular modem supports only a few existing pipes at a time. So we really should not leak them. This change instructs the modem to destroy the pipe if either of the pipe's endpoint (Linux socket) is closed too early.

* Phonet: Pipe End Point for Phonet Pipes protocolRémi Denis-Courmont2008-10-051-0/+114
| | | | | | | | | | | This protocol provides some connection handling and negotiated congestion control. Nokia cellular modems use it for bulk transfers. It provides packet boundaries (hence SOCK_SEQPACKET). Congestion control is per packet rather per byte, so we do not re-use the generic socket memory accounting.
