3331e9c49a STM32 OTGHS host: stm32_in_transfer() fails and returns NAK if a short transfer is received. This causes problems from class drivers like CDC/ACM where short packets are expected. In those protocols, any transfer may be terminated by sending short or NUL packet. 2017-03-07 06:58:59 -06:00

4875c6bbe3 TCP: check for connection before deleting it
It is possible for a socket to have no connection, for example if a TCP
socket is waiting in accept.  This checks for this condition in case the
socket is closed from a different thread.

f1ef2c6cde TCP: attempt to flush the write buffers before closing
When a socket is closed, it should make sure that any pending write
data is sent before the FIN is sent.  It already would wait for all
sent data to be acked, however it would discard any pending write
data that had not been sent at least once.

This change adds a check for pending write data in addition to unacked
data.  However, to be able to actually send any new data, the send
callback must be left.  The callback should be freed later when the socket
is actually destroyed.

b1e09d4847 net/socket and net/tcp: Fix a problem in whent there are multiple network devices. Polls were being sent to all TCP sockets before. This is not good because it means that packets may sometimes be sent out on the wrong device. That is inefficient because it will cause retransmissions and bad performance. But, worse, when one of the devices is not Ethernet, it will have a different MSS and, as a result, incorrect data transfers can cause crashes. The fix is to lock into a single device once the MSS is locked locked down. 2015-08-27 09:06:46 -06:00

12b1c04508 recvfrom(): Correct wait for new data when NET_UDP_READAHEAD is enabled. Fix size accounting when recvfrom_udpreadahead() sets state.rf_recvlen == -1. I have not checked if data are accumulated to the right position in the buffer however.

b493dde4cf TCP networking: In the TCP connection operation, it was trying to setup the network monitor BEFORE the socket was successfully connected. This, of course, has ALWAYS failed because the socket is not yet connected and the TCP state is not yet correct for a connected socket. However, because of other changes net_startmonitor(0 no returns a failure condition that causes worse problems when trying to connect. The fix is to move the logic that starts the network monitor to AFTER the socket has been successfully connected. 2015-05-31 11:35:28 -06:00

33085cb309 Networking: The network device list was protected by a re-entrant semaphore. With the recent change to support network device callback, the network stack needs to access the network device list too. Some drivers, however, run the network stack from the interrupt level -- this is bad but a fact in the current state. Of course,those drivers are unable to take the semaphore and will assert.
The solution here is to eliminate the device devices semaphore altogether.  This eliminates netdev_semtake() and netdev_semgive() and replaces them with net_lock() and net_unlock() which have larger scope as needed for this purpose.
