Gregory Nutt
433f29eea2 net/: Rename CONFIG_TCP_REASSEMBLY to CONFIG_IPv4_REASSEMBLY. Add some fixes to get a clen compile with CONFIG_IPv4_REASSEMBLY enabled. There are several problems with the current implementation: It is untested (and depends on CONFIG_EXPERMIMENTAL). It uses some Ethernet specific definitions (and depends on CONFIG_NET_ETHERNET). There is only a single reassembly buffer. The last two issues prevent use of this feature in any context where IPv4 packets may be reassembled for multiple network devices concurrently). 2018-06-24 12:06:12 -06:00

aabdc00e8c net/: Fix some incorrect comments that go back for years (but have also been cloned in newer files). The network was once interrupt driver, but now runs on the work queue with a semaphore to enforce mutual exclusion. 2018-06-23 14:09:06 -06:00
Gregory Nutt
a0e169ad7b net/: Fix a sixlowpan typo bug recently introduced; Rename g_ipv6_allzeroaddre with the more meaning g_ipv6_unspecaddr since the all-zero address is the IPv6 unspecified address (sometime IN6_ADDR_ANY). Remove more inline tests for IPv6 multicast with tcommint net_is_addr_mcast() macro. Update some comments. 2018-06-23 12:53:27 -06:00

5bb216fb90 net/: There are many different checks for IPv6 multicast addresses. Most of the checks are different. RFC 3513 clearly specifies how to detect an IPv6 multilcast address: they should begin with 0xffxx. I did not change some of the checks in ipv6_input.c, however. In that file, the comments indicate that the code should only pick of certain mulicast address that begin withi 0xff02. 2018-06-23 10:13:38 -06:00

1b6990b69f net/udp: When sending a broadcast (or multicast) packet do not attempt to look up the device by the destination IP address. Rather, use the locally bound address for these cases to select the correct network device. 2018-06-22 08:19:17 -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.

5e2d7c227d net/sixlowpan: TCP send should have PSH and ACK flags set when sending. This matches the standard network (Ethernet) TCP send logic. 2018-05-17 06:45:46 -06:00

19ebdb4ef9 Merged in antmerlino/nuttx/sixlowpan_hc06_fix (pull request #644) 
sixlowpan: Preserve big-endian (network order) when uncompressing address.

This change is the counterpart to another recent endianness fix that occurred on compression of the ip address.

fb8cf9373c net/udp: Resolve race condition in connection-less UDP sockets with read-ahead buffering. 
In connection-mode UDP sockets, a remote address is retained in the UDP connection structure.  This determines both there send() will send the packets and which packets recv() will accept.

This same mechanism is used for connection-less UDP sendto:  A temporary remote address is written into the connection structure to support the sendto() operation.  That address persists until the next recvfrom() when it is reset to accept any address.

When UDP read-ahead buffering is enabled, however, that means that the old, invalid remote address can be left in the connection structure for some time.  This can cause read-ahead buffer to fail, dropping UDP packets.

Shortening the time between when he remote address is reset (i.e., immediately after the sendto() completes) is not a solution, that does not eliminate the race condition; in only makes it smaller.

With this change, a flag was added to the connection structure to indicate if the UDP socket is in connection mode or if it is connection-less.  This change effects only UDP receive operations:  The remote address in the UDP connection is always ignored if the UDP socket is not in connection-mode.

No for connection-mode sockets, that remote address behaves as before.  But for connection-less sockets, it is only used by sendto().

cfc5f86862 net/udp: Minor update from review of 091e3f732e. In connect(), AF_UNSPEC is used to disconnect UDP socket. However, initial commit lacked logic to mark the socket as disconnected. 2018-04-25 10:13:59 -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
