Gregory Nutt d78d3ef4ab Logic for delayed memory garbage collection for the case of user space memory will not work as implemented for the case of the kernel build. That is because the correct context is in place in order to free the user memory when sched_kufree is called, but will not be in place later when the memory garbage collection runs. If this feature is really needed, then some more substantial redesign is required 2015-09-07 14:40:18 -06:00

Gregory Nutt 8840102554 Networking: Divide net_intiialize() into net_setup() and net_initialize() to solve a chicken-and-egg problem. net_setup() must be caleld before up_initialize() is called so that networking data structures are ready to register new network devices.
net_initialize() now does only timer related operations and is called AFTER up_initialize() where the timers are configured.  This is really.

Gregory Nutt 0fcd620404 Move the initialization of the networking subsystem to AFTER up_initialize is called. Fromo Macs Neklyudov. 2015-02-13 13:41:21 -06:00
Gregory Nutt 937f9f23f1 strncpy will not copy the terminating \0 into the destination if the source is larger than the size of the destination. Ensure that the last byte is always zero and let strncpy only copy CONFIG_TASK_NAME_SIZE bytes. The issue of unterminated names can be observed in ps when creating a pthread while CONFIG_TASK_NAME_SIZE is set to 8. 2014-12-17 12:24:02 -06:00

Gregory Nutt 0e3c182e3b Fix error in initialize of IDLE TCB due to last change. The argument list is no long in the TCB, but in the stack. But not for the IDLE task. It needs its own mini-argv[] list so that it looks more like other threads. 2014-09-01 16:49:42 -06:00
