a77c073797 arch/: Fix an interlock that was broken by commit 641a98a434 in all implementations of up_sigdeliver. 2019-02-03 17:14:32 -06:00
Gregory Nutt
641a98a434 arch/: The saved return register state is available on the user stack. Thic commit reorders some logic so that certain, critical registers are preserved in the TCB. This does not make the logic 100% secure, but does prevent some obvious things. sched/signal/sig_delivery: Add a flag to the TCB to indicate that we are in a signal handler. Use this flag to assure that a there a never attempts to nest signal handling operations on a thread. This was guaranteed before but when locking of pre-emption during signal delivering was eliminated in a previous commit, there was a remote possibility of an attempt to do nested signal handling. This flag assures that there is only one signal handled at a time. 2019-02-03 15:29:47 -06:00

ec9265aa95 arch assertions: Correct duplicated logic from commit dbf01d12b7. Checking for PID == zero is not a valid way to test for the IDLE task in all configurations! This is only true in the single CPU configuration. In multiple CPU configurations, there will be a separate IDLE task for each CPU with a different PID. 2018-12-18 17:35:42 -06:00

0af39e1493 arch/: Update all _exit() implementations for all architectures so that they correctly called the scheduler instumentation layer for the new task that runs when the old one exits. This missing instrumentation was confusing the Critical Section Monitor logic with uses this instrumentation to track the state of critical sections. 2018-11-24 18:20:57 -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

977d41d519 Based on a change recommended by Mark Shulte:
Signal handlers maybe run with interrupts enabled or disabled, depending on how the task the received the signal was blocked. (i.e.: If sem_wait() is called, then we disable interrupts, then block the currently running task). This could be dangerous, because user code would be running with interrupts disabled.

This change forces interrupts to be enabled in up_sigdeliver() before executing the signal handler calling up_irq_enable() explicitly.  This is safe because, when we return to normal execution, interrupts will be restored to their previous state when the signal handler returns.

9222f50e1c arch/: Make sure the up_irq_enable() is available on all architectures. I will not be able to test all of these new versions of this function so this may break things for awhile. 2018-06-06 09:25:40 -06:00

9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

libc/semaphore:  Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable.  Changed all references to sem_getvalue in the OS to nxsem_getvalue().

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.

62a1f6f110 up_timer_initialize() is named incorrectly.

6cefbc0c3f This change provides an option to add /dev/urandom to all architectures. The pseudo-random algorithm I choose strikes an arguably-good balance between being "random" and small/fast enough for 8/16 bit MCUs. It’s the well-documented xorshift128 algorithm. It has an internal state of 128 bits that can be [re-]seeded with a write. 2016-07-17 06:42:26 -06:00
