Gregory Nutt 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.

tcp_accept.c net_startmonitor.c always returned zero. In the case where a socket has already been closed, it correctly handled the disconnetion event but still returned OK. Returning OK causes the callers of net_startmonitor to assume that the connection was okay, undoing the good things that net_startmonitor did and causing the socket to be marked as connected. This behavior was noted by Pelle Windestam. 2015-05-28 08:23:51 -06:00

tcp_finddev.c Forgot to add a file in the last commit 2015-05-30 09:17:46 -06:00
tcp_input.c Networking: Fixes an important TCP bug: 16-bit flags was being converted to 8-bits in a few locations, causing loss of status indications 2015-05-27 17:17:42 -06:00
tcp_ipselect.c Networking: Some fixes for compilation when both IPv4 and IPv6 are enabled 2015-01-18 09:23:22 -06:00

tcp_netpoll.c TCP networking: Add support for network driver events 2015-05-30 09:12:27 -06:00
tcp_send_buffered.c Revamp last change. IFF_UP only required when allocating callback, not freeing. 2015-05-30 21:13:58 -06:00

tcp_wrbuffer_dump.c Update everything under nuttx/net to use the corrected syslog interfaces 2014-10-08 10:48:11 -06:00
tcp_wrbuffer.c Networking: Fix another deadlock condition. tcp_write_buffer_alloc() calls sem_wait() with network locked. That worked if CONFIG_NET_NOINTS was not defined because interrupts are automatically restored when the wait happens. But with CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- bad style and also can lead to a deadlock condition 2015-01-28 11:56:11 -06:00
