phonet: some signedness bugs

2011-01-10T21:33:17+00:00

Dan Rosenberg pointed out that there were some signed comparison bugs in the phonet protocol. http://marc.info/?l=full-disclosure&m=129424528425330&w=2 The problem is that we check for array overflows but "protocol" is signed and we don't check for array underflows. If you have already have CAP_SYS_ADMIN then you could use the bugs to get root, or someone could cause an oops by mistake.

Phonet: 'connect' socket implementation for Pipe controller

2010-10-13T21:40:34+00:00

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 Modems

2010-09-28T04:30:41+00:00

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: resource routing backend

2010-09-16T04:31:32+00:00

When both destination device and object are nul, Phonet routes the packet according to the resource field. In fact, this is the most common pattern when sending Phonet "request" packets. In this case, the packet is delivered to whichever endpoint (socket) has registered the resource. This adds a new table so that Linux processes can register their Phonet sockets to Phonet resources, if they have adequate privileges. (Namespace support is not implemented at the moment.)

Phonet: remove dangling pipe if an endpoint is closed early

2010-09-16T04:31:31+00:00

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. Signed-off-by: Rémi Denis-Courmont Signed-off-by: David S. Miller
