2017-09-15libio: Add hold/drop iop referenceSebastian Huber
Check iop reference count in close() and return -1 with errno set to EBUSY in case the file descriptor is still in use. Update #3132.
2017-09-15libio: LIBIO_GET_IOP() LIBIO_GET_IOP_WITH_ACCESS()Sebastian Huber
Replace rtems_libio_check_fd(), rtems_libio_iop(), rtems_libio_check_open() and rtems_libio_check_permissions() combinations with new LIBIO_GET_IOP() and LIBIO_GET_IOP_WITH_ACCESS() macros. Update #3132.
2017-08-25Include missing <string.h>Sebastian Huber

2013-09-12Filesystem: Add and use rtems_filesystem_chmod()Sebastian Huber
Implement POSIX requirements in the high-level file system layer.
2012-12-11libcsupport: GCI Doxygen Task #7Alex Ivanov
http://www.google-melange.com/gci/task/view/google/gci2012/7975223
2012-05-15Filesystem: Move operations to mount table entrySebastian Huber
The scope of the file system operations is the file system instance. The scope of the file system node handlers is the file location. The benefit of moving the operations to the mount table entry is a size reduction of the file location (rtems_filesystem_location_info_t). The code size is slightly increased due to additional load instructions. Restructure rtems_filesystem_mount_table_entry_t to improve cache efficiency.
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
2012-03-13Filesystem: Read-only file system checksSebastian Huber
o Make sure EROFS is indicated for write operations on a read-only file system. o Add error indication for read-only file systems in fchmod() and fchown() according to POSIX.
2012-03-13Filesystem: Reference counting for locationsSebastian Huber
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.

1999-11-17Updated copyright notice.Joel Sherrill
1999-03-01Patch from Eric Norum <eric@skatter.usask.ca> to eliminate externalJoel Sherrill
IO handlers scheme that was implemented originally just to support sockets. The file system IO switch is more general and works fine.
1999-01-20More general fix based on bug report and patch from Ian Lance TaylorJoel Sherrill
<ian@airs.com> to fix this problem: There is a small bug in __rtems_close in c/src/lib/libc/libio.c. It does not check whether the file descriptor it is passed is open. This can cause it to make a null dereference if it is passed a file descriptor which is in the valid range but which was not opened, or which was already closed.
1998-12-10Merged Eric Norum's select patch that was based on 4.0 and resolvedJoel Sherrill
all conflicts.
1998-11-23Added base version of file system infrastructure. This includes a majorJoel Sherrill
overhaul of the RTEMS system call interface. This base file system is the "In-Memory File System" aka IMFS. The design and implementation was done by the following people: + Joel Sherrill (joel@OARcorp.com) + Jennifer Averett (jennifer@OARcorp.com) + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com) + Kerwin Wade (wade@OARcorp.com) PROBLEMS ======== + It is VERY likely that merging this will break the UNIX port. This can/will be fixed. + There is likely some reentrancy/mutual exclusion needed. + Eventually, there should be a "mini-IMFS" description table to eliminate links, symlinks, etc to save memory. All you need to have "classic RTEMS" functionality is technically directories and device IO. All the rest could be left out to save memory.
