Gregory Nutt 29b5b3667f 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

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

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

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
