    Run all .h and .c files modified in last PR through nxstyle.

Author: Xiang Xiao <xiaoxiang@xiaomi.com>

    Net cleanup (#17)

    * Fix the semaphore usage issue found in tcp/udp

    1. The count semaphore need disable priority inheritance
    2. Loop again if net_lockedwait return -EINTR
    3. Call nxsem_trywait to avoid the race condition
    4. Call nxsem_post instead of sem_post

    * Put the work notifier into free list to avoid the heap fragment in the long run.  Since the allocation strategy is encapsulated internally, we can even refine the implementation later.

    * Network stack shouldn't allocate memory in the poll implementation to avoid the heap fragment in the long run, other modification include:

    1. Select MM_IOB automatically since ICMP[v6] socket can't work without the read ahead buffer
    2. Remove the net lock since xxx_callback_free already do the same thing
    3. TCP/UDP poll should work even the read ahead buffer isn't enabled at all

    * Add NET_ prefix for UDP_NOTIFIER and TCP_NOTIFIER option to align with other UDP/TCP option convention

    * Remove the unused _SF_[IDLE|ACCEPT|SEND|RECV|MASK] flags since there are code to set/clear these flags, but nobody check them.

de5a6163d5 This commit implements a proper version of SO_LINGER. Not sufficiently tested on initial commit.
Squashed commit of the following:

    net/: Fix some naming inconsistencies, Fix final compilation issies.

    net/inet/inet_close():  Now that we have logic to drain the buffered TX data, we can implement a proper lingering close.

    net/inet,tcp,udp:  Add functions to wait for write buffers to drain.

    net/udp:  Add support for notification when the UDP write buffer becomes empty.

    net/tcp:  Add support for notification when the TCP write buffer becomes empty.

28f73bd928 net/tcp and udp: Add logic to signal events when TCP or UDP read-ahead data is buffered.
Squashed commit of the following:

    net/tcp:  Add signal notification for the case when UDP read-ahead data is buffered.  This is basically of clone of the TCP notification logic with naming adapted for UDP.

fef255e5be This commit adds an as-of-yet untested implemented of UDP write buffering.
Squashed commit of the following:

    net/udp:  Address most of the issues with UDP write buffering.  There is a remaining issue with handling one network going down in a multi-network environment.  None of this has been test but it is certainly ready for test.  Hence, the feature is marked EXPERIMENTAL.
    net/udp:  Some baby steps toward a corrected write buffering design.
    net/udp:  Remove pesky write buffer macros.
    Eliminate trailing space at the end of lines.
    net/udp:  A little more UDP write buffering logic.  Still at least on big gaping hole in the design.
    net/udp:  Undefined CONFIG_NET_SENDTO_TIMEOUT.
    net/udp:  Crude, naive port of the TCP write buffering logic into UDP.  This commit is certainly non-functional and is simply a starting point for the implementatin of UDP write buffering.
    net/udp:  Rename udp/udp_psock_sendto.c udp/udp_psock_sendto_unbuffered.c.

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

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.

2c251d845c include/net/if.h: Add a bit to the device flags to indicate if the device packet buffer holds an IPv4 or an IPv6 domain packet. Set/clear the flag along with the correct offset to the application payload data as each packet is received.
net/socket, net/tcp, net/udp:  Add logic to select the domain of the outputgoing packet before sending any UDP or TCP packet.  This sets the bit to indicate the IPv4 or IPv6 domain and the correct offset to the output going payload data.
