75b53d563b mm/mm-heap: memalign: fix heap corruption caused by using unaligned chuck size. Unaligned nodes generated by memalign later cause heap corruptions when nodes are shrink further (for example, 24 bytes -> 8 bytes, when alignment is 16 bytes). 2017-10-24 15:35:52 -06:00

34a572b226 Update last commit... Check should really use the definition MMSIZE_MAX which is really the same thing, but guaranteed to be the correct maximum size in any present and future configuration. 2017-10-17 07:34:06 -06:00
EunBong Song
196911d4fa If size is greater than (UINT32_MAX - SIZEOF_MM_ALLOCNODE), malloc size can be overflow by MM_ALIGN_UP macro. For example, if task_create() called with stack_size == -1, up_create_stack() functions allocates SIZEOF_MM_ALLOCNODE bytes for stack. 
This can cause data abort in up_stack_color() function.

a857cc04e4 Fix some build problems after recent separation of internal OS from application interfaces. The build problem only occurs in the PROTECTED and KERNEL builds where separate libraries are built for the applications and for use within the OS. In these cases, the correct interfaces must be used. This commit fixes a few of these, so I can get through build testing, but there are many more that need fixin'. 2017-10-08 08:13:47 -06:00

9e25d89223 Squashed commit of the following: 
Replace all usage kill() in the OS proper with nxsig_kill().

    sched/signal:  Add nxsig_kill() which is functionally equivalent to kill() except that it does not modify the errno variable.

91537a7722 mm/: Heap semaphore logic needs to use nxsem_* interfaces when available, but the standard semaphores only when implementing a user-space heap. Not this does introduce and issue: the memory management functions them become cancellation points because of the use of sem_wait. 2017-10-07 07:16:33 -06:00

7cc63f90d9 sched/semaphore: sem_trywait() modifies the errno value and, hence, should not be used within the OS. Use nxsem_trywait() instead. 2017-10-05 07:59:06 -06:00
Gregory Nutt
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

    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.

5ce2ece134 syslog: Add header file inclusion to eliminate a warning; mm/iob: private function needs static storage class. 2017-05-16 12:26:23 -06:00

6a3800f611 There can be a failure in IOB allocation to some asynchronous behavior caused by the use of sem_post(). Consider this scenario: 
Task A holds an IOB.  There are no further IOBs.  The value of semcount is zero.
Task B calls iob_alloc().  Since there are not IOBs, it calls sem_wait().  The v
alue of semcount is now -1.

Task A frees the IOB.  iob_free() adds the IOB to the free list and calls sem_post() this makes Task B ready to run and sets semcount to zero NOT 1.  There is one IOB in the free list and semcount is zero.  When Task B wakes up it would increment the sem_count back to the correct value.

But an interrupt or another task runs occurs before Task B executes.  The interrupt or other tak takes the IOB off of the free list and decrements the semcount.  But since semcount is then < 0, this causes the assertion because that is an invalid state in the interrupt handler.

So I think that the root cause is that there the asynchrony between incrementing the semcount.  This change separates the list of IOBs:  Currently there is only a free list of IOBs.  The problem, I believe, is because of asynchronies due sem_post() post cause the semcount and the list content to become out of sync.  This change adds a new 'committed' list:  When there is a task waiting for an IOB, it will go into the committed list rather than the free list before the semaphore is posted.  On the waiting side, when awakened from the semaphore wait, it will expect to find its IOB in the committed list, rather than free list.

In this way, the content of the free list and the value of the semaphore count always remain in sync.

59cc4a7a7b Protected mode: Redesign how the user space heap is accessed from the kernel code. It used to call memory management functions in user space via function pointers in the userspace interface. That is inefficient because the first thing that those memory management functions do is to trap back into the kernel to get the current PID. Worse, that operation can be fatal is certain fragile situations such as when a task is exitting. 
The solution is to remove all of the memory management function calls from the interface.  Instead, the interface exports the userspace heap structure and then kernel size implementations of those memory management functions will operate on the userspace heap structure.  This avoids the unnecessary system calls and, more importantly, failures do to freeing memory when a test exits.
