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.

fs_fstatfs.c fstatfs: Rethink last commit. Add verification that the file descriptor refers to an open file. This also should eliminate the warning while doing something useful. 2017-02-22 14:17:14 -06:00
fs_fsync.c Move cancellation point definitions to their own header file. 2016-12-10 09:08:26 -06:00
fs_getfilep.c fs/inode/, fs/vfs/, and sched/task/: File and socket descriptors are no longer allocated for kernel threads. They must use SYSLOG for output and the low-level psock interfaces for network I/O. This saves a little memory which might be important for small footprint configurations. 2016-04-14 10:14:38 -06:00

fs_rename.c rename(): Correct more issues. (1) Move to the root directory in the pseudo file system, (2) Fix path naming calculation when the path is the root directory of a mounted file system, and (3) dont't do the rename if the source and destination of the rename are the same. 2017-02-12 08:37:28 -06:00

fs_stat.c In some cases, packets are still not sent behind the router. I found that NuttX sends the ARP requests not to the router but to the target. Mistake in file net/route/netdev_router.c. From Aleksandr Kazantsev 2017-09-20 13:19:05 -06:00
