* PR2039: Fix NULL pointer accessSebastian Huber2012-03-141-2/+2
| | | | | | | In case rtems_bdbuf_read() returns an error status, the block device buffer pointer will be set to NULL. In RFS the chain node of the block device buffer will be used for RFS purposes. We must not do this after an erroneous read.
* libblock: Change bdbuf APISebastian Huber2012-03-132-22/+25
| | | | | | | | | | | | | | | | | | | | The functions o rtems_bdbuf_get(), o rtems_bdbuf_read(), o rtems_bdbuf_syncdev(), and o rtems_bdbuf_purge_dev(), use now the disk device instead of the device identifier. This makes bdbuf independent of rtems_disk_obtain() and rtems_disk_release(). It is the responsiblity of the file system to obtain the disk device. This also reduces the overhead to get a buffer. The key for the AVL tree uses now the disk device instead of the device identifier. The pointer is interpreted as an unsigned integer. This reduces the memory overhead and makes the comparison operation a bit faster. Removed function rtems_bdbuf_purge_major(). This function was too destructive and could have unpredictable side effects.
* Filesystem: Rename definesSebastian Huber2012-03-132-3/+3
| | | | | | | | | | | | | | | o Removed RTEMS_LIBIO_PERMS_SEARCH. o Renamed RTEMS_LIBIO_PERMS_READ in RTEMS_FS_PERMS_READ. o Renamed RTEMS_LIBIO_PERMS_WRITE in RTEMS_FS_PERMS_WRITE. o Renamed RTEMS_LIBIO_PERMS_EXEC in RTEMS_FS_PERMS_EXEC. o Renamed RTEMS_LIBIO_FOLLOW_HARD_LINK in RTEMS_FS_FOLLOW_HARD_LINK. o Renamed RTEMS_LIBIO_FOLLOW_SYM_LINK in RTEMS_FS_FOLLOW_SYM_LINK. o Renamed RTEMS_LIBIO_MAKE in RTEMS_FS_MAKE. o Renamed RTEMS_LIBIO_EXCLUSIVE in RTEMS_FS_EXCLUSIVE. o Renamed RTEMS_LIBIO_ACCEPT_RESIDUAL_DELIMITERS in RTEMS_FS_ACCEPT_RESIDUAL_DELIMITERS. o Renamed RTEMS_LIBIO_REJECT_TERMINAL_DOT in RTEMS_FS_REJECT_TERMINAL_DOT.
* Filesystem: New defaults fsync_h and fdatasync_hSebastian Huber2012-03-133-5/+5
| | | | | | | New defaults rtems_filesystem_default_fsync_or_fdatasync() and rtems_filesystem_default_fsync_or_fdatasync_success() for fsync_h and fdatasync_h. The rtems_filesystem_default_fsync_or_fdatasync() sets now errno to EINVAL according to POSIX.
* Filesystem: Reference counting for locationsSebastian Huber2012-03-1311-825/+281
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o A new data structure rtems_filesystem_global_location_t was introduced to be used for o the mount point location in the mount table entry, o the file system root location in the mount table entry, o the root directory location in the user environment, and o the current directory location in the user environment. During the path evaluation global start locations are obtained to ensure that the current file system instance will be not unmounted in the meantime. o The user environment uses now reference counting and is protected from concurrent access. o The path evaluation process was completely rewritten and simplified. The IMFS, RFS, NFS, and DOSFS use now a generic path evaluation method. Recursive calls in the path evaluation have been replaced with iteration to avoid stack overflows. Only the evaluation of symbolic links is recursive. No dynamic memory allocations and intermediate buffers are used in the high level path evaluation. No global locks are held during the file system instance specific path evaluation process. o Recursive symbolic link evaluation is now limited by RTEMS_FILESYSTEM_SYMLOOP_MAX. Applications can retrieve this value via sysconf(). o The device file system (devFS) uses now no global variables and allocation from the workspace. Node names are allocated from the heap. o The upper layer lseek() performs now some parameter checks. o The upper layer ftruncate() performs now some parameter checks. o unmask() is now restricted to the RWX flags and protected from concurrent access. o The fchmod_h and rmnod_h file system node handlers are now a file system operation. o The unlink_h operation has been removed. All nodes are now destroyed with the rmnod_h operation. o New lock_h, unlock_h, clonenod_h, and are_nodes_equal_h file system operations. o The path evaluation and file system operations are now protected by per file system instance lock and unlock operations. o Fix and test file descriptor duplicate in fcntl(). o New test fstests/fsnofs01.

The node_access field must be the inode number in the RFS because the file system ops provides no way to tell is a stat call is the result of stat, fstat, or lstat. The solution is to move the file handle to node_access_2 which is also shared with doff but these do not overlap.
