Gregory Nutt 66ef6d143a This commit adds an initial implemented of TCP delayed ACKs as specified in RFC 1122. 
Squashed commit of the following:

    net/tmp:  Rename the unacked field of the tcp connection structure to tx_unacked.  Too confusing with the implementation of delayed RX ACKs.

    net/tcp:  Initial implementation of TCP delayed ACKs.

    net/tcp:  Add delayed ACK configuration selection.  Rename tcp_ack() to tcp_synack().  It may or may not send a ACK.  It will always send SYN or SYN/ACK.

arp Squashed commit of the following: 2019-11-08 11:16:04 -06:00
bluetooth net/: Run nxstyle against all C files. 2019-10-25 11:31:42 -06:00
devif net/: icmp[v6] fix ping[6] complain 'WARNING: Received after timeout'. The root cause is that icmp[v6]_pollsetup monitors ICMP[v6]_NEWDATA, but icmp[v6]_input reports ICMP[v6]_ECHOREPLY. This change lets icmp[v6]_input report report ICMP[v6]_NEWDATA to fix this issue and remove ICMP[v6]_ECHOREPLY to avoid the wrong usage in the future. 2019-11-27 08:09:51 -06:00

igmp net/igmp/igmp_send.c: Fix a typo in a debug statement. Noted by Bernd Walter. 2019-09-25 13:46:24 -06:00
inet This commit adds an initial implemented of TCP delayed ACKs as specified in RFC 1122. 2019-12-08 13:13:51 -06:00

loopback tools/nxstyle.c: Fix logic error that prevent detecion of '/' and '/=' as operators. net/: Minor updates resulting from testing tools/nxstyle. 2019-03-11 12:48:39 -06:00
mld net/: Run nxstyle against all C files. 2019-10-25 11:31:42 -06:00
neighbor Trivial update to some comments. 2019-11-08 12:06:29 -06:00
netdev net/netlink: Redesign the logic that handles notifications of when response data is available. Signal handlers are sub-optimal inside the OS (especially after the preceding change which forces the hand). Instead, use the work queue notifiers as is done with all other network notifiers. 2019-11-28 14:20:40 -06:00
netlink net/netlink/netlink_conn.c: Fix some really basic errors in the redesign of the asynchronous Netlink response logic. 2019-11-28 16:14:59 -06:00
pkt net/netlink/netlink_route.c (mostly): This completes a minimal netlink implementation that will retrieve the ARP table. 2019-11-03 13:59:42 -06:00
procfs net/: Run nxstyle against all C files. 2019-10-25 11:31:42 -06:00
route boards/sim/sim/sim/src/sim_bringup.c: Mount tmpfs to CONFIG_LIBC_TMPDIR in sim_bringup if CONFIG_FS_TMPFS is defined. 2019-11-23 07:58:50 -06:00
sixlowpan This commit adds an initial implemented of TCP delayed ACKs as specified in RFC 1122. 2019-12-08 13:13:51 -06:00

tcp This commit adds an initial implemented of TCP delayed ACKs as specified in RFC 1122. 2019-12-08 13:13:51 -06:00
udp net/: ICMP/ICMPv6/TCP/UDP poll shouldn't set POLLHUP and POLLOUT at the same time the standard require that only report POLLHUP: 2019-11-25 09:59:50 -06:00
usrsock net/usrsock/usrsock_poll.c: usrsock_pollsetup() doesn't need logic and with fds->events since line 279 will do the same thing: 2019-11-25 11:44:58 -06:00
utils net/: Now handles reception of IPv4 packets with larger IPv4 headers containing options. 2019-08-31 12:25:30 -06:00
.gitignore .dSYM only needs to be in the same .gitignore files as .exe 2013-05-30 15:02:04 -06:00
Kconfig net/Kconfig: Ethernet packet buffer size cannot be permitted to go below 1294 is IPv6 is selected. 2019-08-31 09:08:32 -06:00
Makefile net/mld: Add basic build structure for Multicast Listener Discovery (MLD). No real MLD logic yet. Only a few hooks to capture and dispatch MLD ICMPv6 packets. 2018-10-31 14:10:19 -06:00
