93ed8b66d9 net/netlink: Add partial support for the NETLINK poll() operation. Still missing is some signal handling logic that actually wakes up the poll() when an asynchronous NETLLINK response is available. 
So although the poll() implemenation is still not yet usable, the commit is useful because it (1) does not harm, and (2) incidentally fixes a few other issues in the NETLONK response queuing that I noted in the process.

8214973f80 net/usrsock/usrsock_poll.c: usrsock_pollsetup() doesn't need logic and with fds->events since line 279 will do the same thing: 
fds->revents &= (~(POLLOUT | POLLIN) | info->fds->events);

9efadaefc1 net/tcp: Be consistent with units of TIME_WAIT. Units were unspecified in tcp/Kconfig, but assumed to be in units of half seconds in tcp/timer.h. include/nuttx/netconfig does not indicate the units but is apparently assuming seconds. This commit unifies all delays to clearly specified units of seconds. 2019-11-24 09:19:54 -06:00

dbbabcd33c Squashed commit of the following: 
net/netlink/netlink_route.c:  Add Netlink socket NETLINK_ROUTE support for getting a snopshot of the Neighbor table.

    net/neighbor/neighbor_snapshot.c:  Add neighbor_snapshot() that will eventually be used by the Netlink sockets.  Also fixed naming violation 'struct neighbor_entry' -> 'struct neighbor_entry_s'.

    include/nuttx/net/neighbor.h:  Expose format of the IPv6 neighbor table for use with Netlink sockets.

6d13705e93 net/netlink: The NETLINK_ROUTE logic needs to return the first queued response and not attempt to match up reponses with requests. That is the Linux compatible way. Also, use queue.h functions for list management and fix an error in arp_snapshot(). 2019-11-04 09:02:14 -06:00

1ba23bb75c net/udp/udp_psock_sendto_buffered.c: Add a check for the device that is polling. In the multiple network device case, this check is necessary to prevent sending the UDP packet to the wrong device.

f3ab9abe51 net/inet/inet_close.c: Fixes two problems, both noted by Bernd Walter: 
1) The change of commit ed9fe70024 left some dangling logic and incorrect, confusing comments.  Prior to that commit the 'pstate' variable was non-NULL only when doing a lingering close.  Comments to this effect as well as tests of pstate should also have been updated.  These are confusing and inappropriate, but do not lead to incorrect behavior.

2) Eliminate an incomplete test when a disconnection event. When a disconnection event occurs, the close logic MUST always terminate the wait.  The conditional test was not incorrect, however, it lacked 'else' logic and would simply ignore that disconnection event in some cases.  That is bad because there may not be another disconnection event and that can lead to hangs (or at least very, very long delays).
