Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.
Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete. |

More efficient and simpler task termination.
Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.
As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.
task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.
Change in the name of a thread state: Undead -> JoinMe. |

Fix two memory leaks.
In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.
In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up. |

Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();
Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!
Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops. |
