	default n
	---help---
		Enable or disable support for socket options

Squashed commit of the following: net/tcp: Add logic to send probes when SO_KEEPALIVE is enabled. net/tcp: TCP socket should not have to be connected to configure KeepAlive. net/: Add a separate configuration to enable/disable KEEPALIVE socket options. net/tcp: Arguments to TCP keep-alive timing functions probably should be struct timeval as are the times for other time-related socket options. net/tcp: Fix a backward conditional net/tcp: Add some more checks and debug output to TCP-protocol socket options. net/tcp: Cosmetic changes to some alignment. net/: Adds socket options needed to manage TCP-keepalive and TCP state machine logic to detect if that the remote peer is alive. Still missing the timer poll logic to send the keep-alive probes and the state machine logic to respond to probes. 2018-03-12 17:59:46 +01:00			`config NET_TCPPROTO_OPTIONS`

This commit implements a proper version of SO_LINGER. Not sufficiently tested on initial commit. Squashed commit of the following: net/: Fix some naming inconsistencies, Fix final compilation issies. net/inet/inet_close(): Now that we have logic to drain the buffered TX data, we can implement a proper lingering close. net/inet,tcp,udp: Add functions to wait for write buffers to drain. net/udp: Add support for notification when the UDP write buffer becomes empty. net/tcp: Add support for notification when the TCP write buffer becomes empty. 2019-07-01 20:25:32 +02:00			`depends on NET_TCP_WRITE_BUFFERS \|\| NET_UDP_WRITE_BUFFERS`
Squashed commit of the following: Author: Gregory Nutt <gnutt@nuttx.org> Run all .h and .c files modified in last PR through nxstyle. Author: Xiang Xiao <xiaoxiang@xiaomi.com> Net cleanup (#17) * Fix the semaphore usage issue found in tcp/udp 1. The count semaphore need disable priority inheritance 2. Loop again if net_lockedwait return -EINTR 3. Call nxsem_trywait to avoid the race condition 4. Call nxsem_post instead of sem_post * Put the work notifier into free list to avoid the heap fragment in the long run. Since the allocation strategy is encapsulated internally, we can even refine the implementation later. * Network stack shouldn't allocate memory in the poll implementation to avoid the heap fragment in the long run, other modification include: 1. Select MM_IOB automatically since ICMP[v6] socket can't work without the read ahead buffer 2. Remove the net lock since xxx_callback_free already do the same thing 3. TCP/UDP poll should work even the read ahead buffer isn't enabled at all * Add NET_ prefix for UDP_NOTIFIER and TCP_NOTIFIER option to align with other UDP/TCP option convention * Remove the unused _SF_[IDLE\|ACCEPT\|SEND\|RECV\|MASK] flags since there are code to set/clear these flags, but nobody check them. 2019-12-31 16:26:14 +01:00			`select NET_TCP_NOTIFIER if NET_TCP`
