Needed to move the releasing of a semaphore inside of some conditional logic (cosmetic). + * include/nuttx/sched.h, sched/task_setup.c, and sched/task_exithook.c: + Add support for remembering the parent task and sending + SIGCHLD to the parent when the task exists. + * sched/task_exithook.c: Fixed a *critical* bug. Here is + the scenario: (1) sched_lock() is called increments the lockcount + on the current TCB (i.e., the one at the head of the ready to run + list), (2) sched_mergepending is called which may change the task + at the head of the readytorun list, then (2) sched_lock() is called + which decrements the lockcount on the wrong TCB. The failure case + that I saw was that pre-emption got disabled in the IDLE thread, + locking up the whole system. |
