97339e47f1 Check return from nxsem_wait_initialize() 
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution:  Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly.  This commit is only for those files under graphics/, mm/, net/, sched/, wireless/bluetooth.

Still to do:  Files under fs/, drivers/, and arch.  The last is 116 files and will take some effort.

44b8f3e467 include/nuttx/sched.h: Move prototype for sched_releasetcb() 
Move the prototype for the internal OS from from sched/sched/sched.h to include/nuttx/sched.h.  This was done because binfmt/binfmt/excecmodule.c requires the prototype for sched_releasetcb() and was illegally including sched/sched/sched.h.  That is a blatant violation of the OS modular design and the person that did this should be hung up by their thumbs.  Oh... I did that back in a bad moment in 2014.  Now that is made right.

6a3c2aded6 Fix wait loop and void cast (#24) 
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

3c30cf1f05 Squashed commit of the following: 
task_spawn() and posix_spawn() are NuttX OS interfaces.  In PROTECTED and KERNEL build modes, then can be reached from applications only via a system call.  Currently, the number of parameters in a system call is limited to six; these spawn function have seven parameters.  Rather than extend the maximum number of parameters across all architectures, I opted instead to marshal the seven parameters into a structure.
     *

In order to support builtin in function in protected mode, a task_spawn() system call must be supported.  Unfortunately this is overly complex because there is a (soft) limit of 6 parameters in a system call; task_spawn has seven paramters.  This is a soft limit but still difficult to extend because it involves assembly language changes to numerous architectures.  Better to get more creative.

8e321aba84 sched/: Correct some naming. The NuttX task groups have been using the acroynum 'gid' and also the type 'gid_t' for the the task group ID. That is incorrect. Than naming is reserved for use with group permissions. So these were all named to grpid and grpid_t so that it is clearer that these refer to NuttX task group IDs, and not to group permissions. 2019-08-02 10:01:30 -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.
