4c800ca372 sched/task/task_exithook.c: Update some commits. include/nuttx/sched.h: Fix some complaints from nxstyle. 2019-08-02 08:49:26 -06:00

eda7f5f379 sched/task/task_exithook.c: nxtask_signalparent() in task_exithook.c may invalidate the group's parent task ID (tg_ppid) too soon. The tg_ppid field is use only to remember the parent tasks ID so that it can send the SIGCHLD signal to it. So it must stay valid until SIGCHLD has been sent. In nxtask_signalparent(), it calls nxtask_sigchild() to send SIGCHLD to the parent, then invalidates tg_ppid. That would be okay, except that the SIGCHLD is only sent when the last member of the group terminates. That is incorrect; tg_ppid can be invalidated too soon and, as a consequence, SIGCHLD would never be sent.

c2136fda6d sched/signal/sig_default.c: The abnormal termination handler was just calling exit() conditionally when, for example, Ctrl-C is sent to a task. The abnormal termination handler must obey the rules of cancellation points: If cancelation is disabled, then the abnormal termintion logic must wait for cancelation to be re-enabled; If cancellation is deffered then the abnormal termination logic may have to wait for the victim task to enter or exit a cancellation point. 2019-05-17 07:39:04 -06:00

0863e771a9 Revert "sched/clock/clock_initialize.c: clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."
This reverts commit 2bc709d4b9.

Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case.  However, this change has the side-effect of breaking every implementation of tickless mode:  After this change the tickless timer structures are used before they are initialized in clock_inittime().  Initialization happens later when up_initialize is called() when arm_timer_initialize().

Since the tickless mode timer is very special, one solution might be to

1. Rename xxx_timer_initialize to up_timer_initialize
2  Move up_timer_initialize to include/nuttx/arch.h
3.  Call it from clock subsystem instead up_initialize

Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).

For now, however, we just need to revert the change.

0951151c33 libs/libc/pthread, syscall/, and include/sys/syscall.h: Support for pthread_mutex_timedlock() was added recently, however no new system call was added for the API make is usable only in the FLAT build. With a pthread_mutex_timedlock() system call, there is no reason for a pthread_mutex_lock() system call since it is now nothing more than an wrapper around pthread_mutex_timedlock(), passing NULL for the time value. The pthread_mutex_lock() syscall was removed and the pthread_mutex_lock() implemented was moved from /sched/pthread to where it now belows in libs/libc/pthread. 2019-02-25 18:19:13 -06:00

40cdc187bb mm/mm_heap/mm_sem.c and sched/task/task_getpid.c: Commits 43d37c866b and f37202cbc0 resolved some problems with the original fix of 91aa26774b. However, Those changes used an internal OS interface (sched_self()) which is not available when the the user-space memory manager is built in the PROTECTED or KERNEL builds and resulted in build failures.
This commit repartitions the logic by moving some of the changes from mm_sem.c into task_getpid.c.  The logic is equivalent for the case of mm_trysemaphore(), but no has wider impact since it potentially affects all callers of getpid().  Hence, this change may also introduce some other issues that will need to be addressed.

9d1c845dcc Revert "This patch prevent heap corruption as in below case."
This solution to the problem noted by EunBong Song results in major memory fragmentation and and out-of-memory conditions on the PX4 platform.  On that platform the lower priority work queue is very low priority and essentially never runs when the system is busy.  As a result, the systems gets slowly starved of memory until failures and bad behaviors begin to occur.

This is an addition patch coming later to result the original problem in a different way that does not have cause memory starvation.

This reverts commit 91aa26774b.

454d59b049 sched/sched_foreach.c: sched_foreach() should not have to hold the critical section over the entire traversal. It should be acceptable to simply only the critical section while one entry is being processed (the caller can always call sched_foreach within a critical section is greater stability is needed. sched/sched_gettcb.c: Recent changes removed critical sections around calls to sched_gettcb.c. However, there is a very should sequence of instructions that actually does require the critical section. That short sequence no manages its own critical section. 2018-11-29 13:09:56 -06:00

1ac9558460 sched/irq and sched/sched: Measurement of interrupt handler duration used to be available only in Tickless mode since it used the high resolution Tickless timer to measure interrupt time. This commit adds CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the interrupt duration caculation to use the same high-resolution, platform-specific timer as is used with the Critical Section Monitor. This leads to two improvements: (1) You can now measure interrupt duration in non-Tickless mode, and (2) in either mode, the interrupt duration and the critical section measures will use the same high-resulotion timer and should, therefore, never be any descripancy due to different clock sources. 2018-11-26 11:29:20 -06:00

dbf01d12b7 Assertions: Identify the running task correctly when dumping task state information. It takes time to switch to the target task after g_readytorun has been modified. If panic/assert happen during this period, the dump will contain the incorrect and confusing information due to the difference between the real running task and the return value of this_task(). This change resolve this problem by adding g_running_task to track the real running task through the context switch. 2018-11-15 07:11:51 -06:00
