History

Gregory Nutt b3f0aab00a Squashed commit of the following: sched/wqueue/kwork_notifier.c: Redesign some data structures. struct works_s must appear at the beginning of the notifier entry structure. That is because it contains the work queue indices. This solves a harfault issue. net/tcp/tcp_netpoll.c: tcp_iob_work() needs to free the allocated argument when it is finished. net/tcp/tcp_send_buffered.c: Extend psock_tcp_cansend() so that it also requires that at least on IOB is also avaialble. mm/iob: iob_navail() was returning the number of free IOB chain queue entries, not the number of free IOBs. Completely misnamed. net/tcp/tcp_netpoll.c: Add logic to receive notifications when IOBs are freed (Needs CONFIG_NET_TCP_WRITE_BUFFERS and CONFIG_IOB_NOTIFIER). At present, does nothing because the logic in in psock_tcp_cansend() does not check for the availability of IOBs. That will change.		2018-09-12 08:57:06 -06:00

arp	net/arp/arp_out.c: Fix some backward logic in an if condition.	2018-08-29 10:51:44 -06:00
bluetooth	Fix some errors in last commits found in build testing.	2018-07-19 10:30:52 -06:00
devif	Rename the file devif_loopbackout.c to devif_loopback.c	2018-08-25 08:36:02 -06:00
icmp	net/icmp and icmpv6: Fix failure to poll ICMP socket issue.	2018-08-26 15:37:03 -06:00
icmpv6	net/icmp and icmpv6: Fix failure to poll ICMP socket issue.	2018-08-26 15:37:03 -06:00
ieee802154	net/ and include/nuttx/net: Add getpeername() support	2018-07-19 07:16:30 -06:00
igmp	Replace all ASSERT with DEBUGASSERT to save the code space	2018-08-24 06:58:30 -06:00
inet	net/usrsock: Optimize option dependence	2018-08-26 15:05:46 -06:00
ipforward	net/arp: Improve arp_find() commit `9774d35010` to reduce the amount and frequency of data copies.	2018-08-25 07:12:21 -06:00
local	net/ and include/nuttx/net: Add getpeername() support	2018-07-19 07:16:30 -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
neighbor	net/: Fix a sixlowpan typo bug recently introduced; Rename g_ipv6_allzeroaddre with the more meaning g_ipv6_unspecaddr since the all-zero address is the IPv6 unspecified address (sometime IN6_ADDR_ANY). Remove more inline tests for IPv6 multicast with tcommint net_is_addr_mcast() macro. Update some comments.	2018-06-23 12:53:27 -06:00
netdev	mm/iob: IOB free notifier should accept the work queue ID as a paramter. The notification may need to run on either the high- or low- priority work queue. sched/work: Change the default priority of the low-priority work queue to 100.	2018-09-11 08:49:39 -06:00
netlink	This commit brings in a fragmentary, experimental implementation of NETLINK sockets. There is not too much to that socket support on this initial commit, just the netlink socketer framework. However, I decided to bring it into master because there is a enough that I would not want to lose what is in place. And since it is dependent on CONFIG_EXPERIMENATL, its presence on master should be innocuous.	2018-08-03 13:22:36 -06:00
pkt	net/ and include/nuttx/net: Add getpeername() support	2018-07-19 07:16:30 -06:00
procfs	net/procfs/netdev_statistics.c: Was not handling the output correct for the case of an IEEE 802.11 device.	2018-08-21 09:08:29 -06:00
route	Remove trailing spaces at the end of lines.	2018-08-13 07:39:38 -06:00
sixlowpan	Fix lots of typos in C comments and Kconfig help text	2018-07-08 18:24:45 -06:00
socket	net/socket/getsockname.c: Add psock_getsockname function	2018-08-26 14:43:13 -06:00
tcp	Squashed commit of the following:	2018-09-12 08:57:06 -06:00
udp	net/tcp/tcp_netpoll.c: Add logic to receive notifications when IOBs are freed (Needs CONFIG_NET_TCP_WRITE_BUFFERS and CONFIG_IOB_NOTIFIER). At present, does nothing because the logic in in psock_tcp_cansend() does not check for the availability of IOBs. That will change.	2018-09-12 06:40:18 -06:00
usrsock	net/usrsock: Add the listen/accept/getpeername/ioctl support	2018-08-26 15:15:48 -06:00
utils	Update some comments.	2018-07-07 15:23:46 -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: Uncomment the prompt of NET_SLIP_PKTSIZE	2018-08-26 14:28:35 -06:00
