Gregory Nutt 5a416be95b net/tcp: Same change to tcp_send_buffered.c probably also applies to tcp_send_unbuffered.c.		2017-10-19 16:14:38 -06:00

arp	Squashed commit of the following:	2017-10-03 15:35:24 -06:00
devif	There was a possible recursion that could eventually overflow the stack. The error occurred when closing the socket with inet_close() while a socket callback was still queued. When the socket callback was executed by devif_conn_event(), this resulted in a call to psock_send_eventhandler() with TCP_CLOSE flag set which then called tcp_lost_connection(). tcp_shutdown_monitor() then called tcp_callback() again, which again called psock_send_eventhandler(), and so on.... Noted by Pascal Speck. Solution is also similar to a solution proposed by Pascal Speck.	2017-10-19 11:55:51 -06:00

inet	TCP Networking: When CONFIG_NET_TCP_WRITE_BUFF=y there is a situation where a NULL pointer may be dereferenced. In this configuration, the TCP connection's 'semi-permnanent' callback, s_sndcb was nullified in tcp_close_disconnect. However, other logic in tcp_lost_connection() attempt to use that callback reference after it was nullifed. Fixed in tcp_lost_connectino() by adding a NULL pointer change before the access. This was reported by Dmitriy Linikov in Bitbucket Issue 72.	2017-10-13 06:47:40 -06:00
ipforward	net/: Fix some build issues noted when both IPv4 and IPv6 are enabled.	2017-10-18 11:08:56 -06:00
local	net/local: Missed at least one change from read() to nx_read().	2017-10-11 12:16:00 -06:00
loopback	Fix IPv6 loopback driver that depended on the removed g_ipv6_allonesaddr. Noted by Masayuki Ishikawa	2017-08-09 06:59:55 -06:00

procfs	Trivial fix in some comments.	2017-09-20 10:06:26 -06:00
route	Squashed commit of the following:	2017-10-04 15:22:27 -06:00
sixlowpan	The nx example no longer supports single user mode.	2017-10-14 10:54:38 -06:00
socket	There was a reference counting problem in the TPC logic of net_clone(). net_clone() which is the common logic underlying dup() and dup2() for sockets. When net_clone() calls net_start_monitor() and net_start_monitor() returns a failure (because the underlying TCP connection) then net_clone() must back out the reference count on the structure. Problem noted by Pascal Speck and this implementation of the solution is based on his suggestion.	2017-10-19 11:09:23 -06:00
tcp	net/tcp: Same change to tcp_send_buffered.c probably also applies to tcp_send_unbuffered.c.	2017-10-19 16:14:38 -06:00
udp	There was a possible recursion that could eventually overflow the stack. The error occurred when closing the socket with inet_close() while a socket callback was still queued. When the socket callback was executed by devif_conn_event(), this resulted in a call to psock_send_eventhandler() with TCP_CLOSE flag set which then called tcp_lost_connection(). tcp_shutdown_monitor() then called tcp_callback() again, which again called psock_send_eventhandler(), and so on....

usrsock	There was a possible recursion that could eventually overflow the stack. The error occurred when closing the socket with inet_close() while a socket callback was still queued. When the socket callback was executed by devif_conn_event(), this resulted in a call to psock_send_eventhandler() with TCP_CLOSE flag set which then called tcp_lost_connection(). tcp_shutdown_monitor() then called tcp_callback() again, which again called psock_send_eventhandler(), and so on.... Noted by Pascal Speck. Solution is also similar to a solution proposed by Pascal Speck.	2017-10-19 11:55:51 -06:00
utils	sched/semaphore: sem_timedwait() is a cancellation point and, hence, cannot be called from within the OS. Created nxsem_timedwait() that is equivalent but does not modify the errno and does not cause cancellation. All calls to sem_timedwait() change to calls to nxsem_timedwait() in the OS.	2017-10-05 07:24:54 -06:00
.gitignore	.dSYM only needs to be in the same .gitignore files as .exe	2013-05-30 15:02:04 -06:00

Makefile	Squashed commit of the following:	2017-08-19 08:48:52 -06:00
net_initialize.c	Addes support for read-only routing tables. Prior to this change, routing tables were only support in RAM and had to be initialized with explicit logic to add the necessary routes to the routing table. With this change, routes may be defined in the pre-initialized, read-only routing table provided by the board-specific logic	2017-09-28 09:04:31 -06:00
