969d7c5814 Networking: Remove driver based backlog support. This affects the entire network, but is used by only one driver. The only supported with of supported RX backlog is via common read-ahead buffering. 2017-08-21 06:28:59 -06:00
Gregory Nutt
bd7c84b23e Remove CONFIG_NETDEV_MULTINIC. This increases code size by a little, but greatly reduces the complexity of the network code. 2017-08-08 14:24:12 -06:00

572cf51fa4 Networking: Rethink IPv6 all-nodes packet routing. 2017-08-08 07:48:07 -06:00

835ae2999d networking: Move a little more to the inet/ subdirectory. 2017-08-07 13:03:23 -06:00

2ada7d5892 IPv6: Remove comparisons to the address with all ones set. IPv6 does not support broadcast addresses and certainly not in that form. Replace with multicast addresses beginning with 0xff02. 2017-08-07 11:50:50 -06:00

d9a2a3c3f1 Networking: When upd_input() cannot process a packet, it returns ERROR so that network drivers may try calling ipv4_input() later. In this case, it must also set d_len to zero. Otherwise, all network drivers will assume tht there is also an outgoing packet. This results in a gratuitous ARP. 2017-07-17 06:50:39 -06:00

aa2e9c15a5 IP forwarding: Major rearchitecting of the outgoing portion of the IP forwarding logic necessary into to properly received device-related forwarding events. 2017-07-07 20:19:26 -06:00

803235ad4b IP forwaring: Rename some files to get closer to other naming conventions. 2017-07-07 18:45:58 -06:00

7258f1cbfc IP forwarding: Move to separate directory. A few fixes from early testing; In TUN driver, do all polling on worker thread. Otherwise, the stack gets very deep. 2017-07-07 18:33:06 -06:00

b5d7187df6 IP forwarding design simplication; might save some memory. Also fix some compile issues introduce with last commit in MULTINIC configration. 2017-07-06 16:19:10 -06:00

b297066eb9 IP Forwarding: Add IPv4 packet forwarding logic. Initial commit is an untested clone of the IPv6 forwarding logic with a few minor logic changes for IPv4. 2017-07-05 15:12:29 -06:00

edf16c5805 IP forwarding: In check it the Ethernet MAC address is in the ARP/Neighbor table, add an additional check to skip in the case of CONFIG_NET_MULTILINK and the devices is not an Ethernet device. 2017-07-05 12:40:26 -06:00

31f832d8c5 IP forwarding: Flesh out TCP, UDP, and ICMPv6 packet forwarding logic. 2017-07-05 11:01:16 -06:00

5e617f8410 UDP networking: The TTL (time to live) was not being set in the IPv4 or IPv6 header unless the UDP socket was bound. 2017-07-04 12:05:21 -06:00
Gregory Nutt
c0c275c8fc IP forwarding. Adds a little more structure to handle passing packets received on one network device to another network device. Logic is still incomplete. 2017-07-04 10:19:52 -06:00

bfb93338f6 Move net/iob to drivers/iob so that the I/O buffering feature can be available to other drivers when networking is disabled. 2017-04-20 16:08:49 -06:00

bcc6b61fc1 Move include/nuttx/net/iob.h to include/drivers/iob.h; rename CONFIG_NET_IOB to CONFIG_DRIVERS_IOB 2017-04-20 14:53:30 -06:00

cd3c9634c8 Add user-space networking stack API (usrsock) 
User-space networking stack API allows user-space daemon to
provide TCP/IP stack implementation for NuttX network.

Main use for this is to allow use and seamless integration of
HW-provided TCP/IP stacks to NuttX.

For example, user-space daemon can translate /dev/usrsock
API requests to HW TCP/IP API requests while rest of the
user-space can access standard socket API, with socket
descriptors that can be used with NuttX system calls.
