* Filesystem: Reference counting for locationsSebastian Huber2012-03-13166-7519/+6155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* score: Add _RBTree_Opposite_direction.Gedare Bloom2012-03-042-8/+18
| | | | | Add a red-black tree helper method to ease obtaining the direction opposite to the current direction. Useful for manipulating and traversing an rbtree.

* Add functions for greedy workspace allocationSebastian Huber2012-02-173-0/+57
| | | | | | | Various tests must check program paths that result due to failed memory allocations from the workspace. To avoid tinkering with internal workspace structures throughout the test code these functions should be used.

* PR 2001/shell - medit command argument parsing correctionJoel Sherrill2012-02-031-3/+1
| | | | | | | | | | | "medit" overran the argument list, choking on the NULL pointer following the last argument. Note that "medit" still only does byte-sized accesses, which limits its usefulness on most systems.

* PR 1991/cpukit - attr.c (really mode code) warning reworkJoel Sherrill2012-02-023-8/+33
| | | | | | | | | | | | | | This PR was about a warning for no previous prototype for rtems_interrupt_level_attribute. This method exists (like a few others) to have real bodies for Classic API services implemented as macros. These macros are not available from anything but C and C++. The most explicit use was in the Ada binding but these would be needed from assembly language or any other non-C based language. On top of needing a prototype, the methods were misnamed. They were related to modes. This renames them, moves the file, fixes test code, etc.
