2008-12-17Phonet: use atomic for packet TX windowRémi Denis-Courmont
GPRS TX flow control won't need to lock the underlying socket anymore. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-03Phonet: basic net namespace supportRémi Denis-Courmont
Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-26Phonet: include generic link-layer header size in MAX_PHONET_HEADERRemi Denis-Courmont
This fixes an OOPS in hard_header if a Phonet address is assigned to a non-Phonet network interface. Signed-off-by: Remi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-05Phonet: implement GPRS virtual interface over PEP socketRémi Denis-Courmont

2008-10-05Phonet: receive pipe control requests as out-of-band dataRémi Denis-Courmont

2008-10-05Phonet: Pipe End Point for Phonet Pipes protocolRémi Denis-Courmont
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. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-05Phonet: connected sockets glueRémi Denis-Courmont
Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Acked-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-22Phonet: emit errors when a packet cannot be delivered locallyRemi Denis-Courmont
When there is no listener socket for a received packet, send an error back to the sender. Signed-off-by: Remi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-22Phonet: proc interface for port rangeRemi Denis-Courmont
Phonet endpoints are bound to individual ports. This provides a /proc/sys/net/phonet (or sysctl) interface for selecting the range of automatically allocated ports (much like the ip_local_port_range with IPv4).

2008-09-22Phonet: Phonet datagram transport protocolRemi Denis-Courmont
This provides the basic SOCK_DGRAM transport protocol for Phonet. Signed-off-by: Remi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-22Phonet: common socket glueRemi Denis-Courmont
This provides the socket API for the Phonet protocols family. Signed-off-by: Remi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-22Phonet: Netlink interfaceRemi Denis-Courmont
This provides support for configuring Phonet addresses, notifying Phonet configuration changes, and dumping the configuration. Signed-off-by: Remi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-22Phonet: network device and address handlingRemi Denis-Courmont
This provides support for adding Phonet addresses to and removing Phonet addresses from network devices. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-22Phonet: PF_PHONET protocol family supportRemi Denis-Courmont
This is the basis for the Phonet protocol families, and introduces the ETH_P_PHONET packet type and the PF_PHONET socket family. Signed-off-by: Remi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
