9774d35010 net/arp: Make the function arp_find() thread-safe. It now returns a copy of the ARP table entry, rather than a potentially unstable reference to the ARP table entry. 2018-08-24 17:36:08 -06:00

a186383f2a Recent changes to UDP in order to correct problems with UDP connection mode introduced a new bug: The 'to' address passed to sendto() must now be NULL in connection mode. But there are errors because there was one place where the 'to' address was still being used. 
This commit adds logic to first check for UDP connection mode.  If the UDP socket is connected, then the NULL 'to' address is ignored and saved connection address is used instead.

434da18cd7 net/udp: Correct an error introduce in recent fixes for UDP connected sockets. The interaction between psock_udp_send() and psock_udp_sendto() was perverse: It should always pass a NULL destinatino address. 2018-04-26 21:58:09 -06:00

091e3f732e net/udp: Fix several issues using connected UDP sockets: sendto() should not accept and address. Normally send() should be used instead. recvfrom() is no longer necessary. recvfrom() and poll() should not reset to accept any addresses but should, instead, only accept inputs and events from the connected remore peer. On of these issues was noted by 李桂丁 <liguiding@pinecone.net>. Changes were made as summarized here: http://www.masterraghu.com/subjects/np/introduction/unix_network_programming_v1.3/ch08lev1sec11.html 2018-04-25 08:43:38 -06:00

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.
