A testcase as following:
child_task()
{
sleep(3);
}
main_task()
{
while (1)
{
ret = task_create("child_task", child_task, );
sleep(1);
task_delete(ret);
}
}
Root casuse:
task_delete hasn's cover the condition that the deleted-task
is justing running on the other CPU.
Fix:
Let the nxsched_remove_readytorun() do the real work

1. When pthread exit, set the default cancellability state to NONCANCELABLE state.
2. Make sure modify tcb->flags is atomic operations.

Same as with group_free(), there is no need to instantiate the address
environment to destroy it.
The only problem was the ARM implementation modified the L1 mappings
in up_addrenv_destroy(), which it no longer does.
This is unnecessary, the address environment is getting wiped anyway,
there is no need to remove the L1 references because they will get
wiped when the page directory is changed
This is just unnecessary, a process cannot be destroyed by another
process in any case, every time this is executed the active address
environment is the process getting destroyed.
Even in the hypothetical case this was possible, the system would
crash at once if a context switch happens between "select()" and
"restore()", which is possible as the granule allocator is protected by
a semaphore (which is a synchronization point).
This implements the file system logic for posix shared memory:
shm_open, shm_unlink, mmap, munmap and close
For flat and protected builds the memory simply allocated from (user) heap
For kernel build the memory is allocated from page pool and mapped with MMU
This doesn't yet support protection flags or re-sizing already truncated shared
memory area.

UDP linger timeout will be wrongly converted to UINT_MAX by _SO_TIMEOUT() when it is set to 0,
net/socket/socket.h:
|
| # define _SO_TIMEOUT(t) ((t) ? (t) * MSEC_PER_DSEC : UINT_MAX)
net/udp/udp_close.c:
|
| if (_SO_GETOPT(conn->sconn.s_options, SO_LINGER))
| {
| timeout = _SO_TIMEOUT(conn->sconn.s_linger);
| }
this change will correct this behavior, if the linger is set to 0, the timeout value should be 0

if the wrbuffer does not have enough space to send the rest of
the data, then the send function will loop infinitely in nonblock
mode, add send timeout check to avoid this issue.
