7c96a25ec1 can: prevent integer overflow in can_write
Because buflen is size_t (unsigned) and nsent is ssize_t (signed)
of the same size, (buflen - nsent) results in unsigned and
overflows if nsent > buflen.

This happens when sending CAN FD frame with DLC > 8 and a user
gets the buflen parameter as a result of CAN_MSGLEN(len)
where `len' is the size of data which is less then a size
for some extended DLC  (e.g. 26 bytes is sent in a message with
DLC 0xD, which has 32 bytes of data).

The correct buflen value should be rather
  CAN_MSGLEN(can_dlc2bytes(can_bytes2dlc(len)))

d452a05910 pollnotify: we should send poll events before semaphore incrementes.
There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!

41efa2ae72 drivers/can/can.c: Fix errors with pointers when using internal OS interface (#118)
Author: Gregory Nutt <gnutt@nuttx.org>

    Run all .c and .h files in last PR through tools/nxstyle and correct all coding standard complaints.

Author: Oleg <ev.mipt@gmail.com>

    * Fix CAN driver to work with internal OS interfaces.  Store internal file pointer in f_priv and use it then to distinct readers (See issue #111)
    * Store reader pointer in f_priv instead of filep
    * Don't need in filep in can_reader_s

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

936df1bcb5 Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep().
Squashed commit of the following:

    Change all calls to usleep() in the OS proper to calls to nxsig_usleep()

    sched/signal:  Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable.

    sched/signal:  Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.

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:  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.
