Jussi Kivilinna 547733cbb0 Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00
..
arp Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00
devif 6LoWPAN: The original, Contiki-based design used only a single buffer for reassemblying larger packets. This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently. These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets. The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address. This assures that there can be be no corruption of the reassembly once it has started. 2017-08-26 10:00:47 -06:00
icmp Networking: A little more wording changes related to interrupts vs. events 2017-08-29 15:08:38 -06:00
icmpv6 Networking: A little more wording changes related to interrupts vs. events 2017-08-29 15:08:38 -06:00
ieee802154 Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00
igmp Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00
inet Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00
ipforward Networking: Clean up some naming that has bothered me for a long time... There are no interrupts and no interrupt handlers in the network. There are events and event handler (there used to to be interrupt logic in there years ago but that is long, long gone). 2017-08-29 14:08:04 -06:00
local net/local: fix server lc_waitsem overflow 2017-09-01 07:47:29 -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 Networking: Fix netdev_dev_lladdrsize. In some configurations, it could return the wrong size for the address of a packet radio. 2017-08-08 16:27:23 -06:00
netdev Networking: Rethink last fix. We can make this less protocol dependent. 2017-08-23 15:30:56 -06:00
pkt Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00
procfs Network procfs: procfs/net_procfs_route.c building error occur if CONFIG_NET_ROUTE is enabled. Fix suggested by Aleksandr Kazantsev 2017-08-22 10:21:07 -06:00
route Forgot to add a file in the last commit 2017-08-10 16:31:25 -06:00

socket Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00
tcp Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00

usrsock Update net_timedwait() and net_lockedwait() call sites to handle negated errno in return value 2017-09-04 07:56:51 -06:00
utils Fix net_lock returning ERROR when instead of real error code on failure. 2017-09-01 07:18:16 -06:00
