* | net: pass kern to net_proto_family create functionEric Paris2009-11-061-1/+1
|/ | | | | | | | | | | The generic __sock_create function has a kern argument which allows the security system to make decisions based on if a socket is being created by the kernel or by userspace. This patch passes that flag to the net_proto_family specific create function, so it can do the same thing.

* net: sk_drops consolidationEric Dumazet2009-10-152-2/+0
| | | | | | | | | | | sock_queue_rcv_skb() can update sk_drops itself, removing need for callers to take care of it. This is more consistent since sock_queue_rcv_skb() also reads sk_drops when queueing a skb. This adds sk_drops managment to many protocols that not cared yet.

* net: Generalize socket rx gap / receive queue overflow cmsgNeil Horman2009-10-122-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a new socket level option to report number of queue overflows Recently I augmented the AF_PACKET protocol to report the number of frames lost on the socket receive queue between any two enqueued frames. This value was exported via a SOL_PACKET level cmsg. AFter I completed that work it was requested that this feature be generalized so that any datagram oriented socket could make use of this option. As such I've created this patch, It creates a new SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a SOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue overflowed between any two given frames. It also augments the AF_PACKET protocol to take advantage of this new feature (as it previously did not touch sk->sk_drops, which this patch uses to record the overflow count). Tested successfully by me. Notes: 1) Unlike my previous patch, this patch simply records the sk_drops value, which is not a number of drops between packets, but rather a total number of drops. Deltas must be computed in user space. 2) While this patch currently works with datagram oriented protocols, it will also be accepted by non-datagram oriented protocols. I'm not sure if thats agreeable to everyone, but my argument in favor of doing so is that, for those protocols which aren't applicable to this option, sk_drops will always be zero, and reporting no drops on a receive queue that isn't used for those non-participating protocols seems reasonable to me. This also saves us having to code in a per-protocol opt in mechanism. 3) This applies cleanly to net-next assuming that commit 977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* net: add IEEE 802.15.4 socket family implementationSergey Lapin2009-06-096-0/+1072
Add support for communication over IEEE 802.15.4 networks. This implementation is neither certified nor complete, but aims to that goal. This commit contains only the socket interface for communication over IEEE 802.15.4 networks. One can either send RAW datagrams or use SOCK_DGRAM to encapsulate data inside normal IEEE 802.15.4 packets. Configuration interface, drivers and software MAC 802.15.4 implementation will follow. Initial implementation was done by Maxim Gorbachyov, Maxim Osipov and Pavel Smolensky as a research project at Siemens AG. Later the stack was heavily reworked to better suit the linux networking model, and is now maitained as an open project partially sponsored by Siemens.
