2015-01-28IMFS: Aggregate link support in dedicated modulesSebastian Huber1-137/+0
2015-01-27IMFS: Replace node union with individual structSebastian Huber1-13/+23
This reduces the average node size. Add and use IMFS_GENERIC_INITIALIZER().
2014-11-26imfs/imfs_handlers_link.c: Add _Assert for NULL pointerJosh Oguin1-0/+2
CodeSonar flagged this as a possible dereference of a NULL pointer. This should never occur so adding _Assert().
2014-03-21Change all references of rtems.com to rtems.org.Chris Johns1-1/+1
2013-12-20Filesystem: Use default kqfilter and poll handlerSebastian Huber1-0/+2
2013-12-20Filesystem: Add readv/writev handlersSebastian Huber1-11/+13
The readv() and writev() support was implemented in terms of multiple calls to the read and write handlers. This imposes a problem on device files which use an IO vector as single request entity. For example a low-level network device (e.g. BPF(4)) may use an IO vector to create one frame from multiple protocol layers each with its own IO vector entry.

2012-10-07Filesystem: Reject removal of root nodesSebastian Huber1-3/+2
Reject the removal of file system instance root nodes in rmdir() and unlink() and return the EBUSY error status. File system instances can be removed with unmount(). Remove root node special cases in IMFS, DOSFS, and RFS.
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
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.
2012-03-13IMFS: Node specific stat handlersSebastian Huber1-1/+23
2012-03-13IMFS: Add and use node controlSebastian Huber1-4/+65
Add and use structure IMFS_node_control with support functions. This helps to make high level functions independent of the node type and reduces the number of branches in the code.
2012-03-13Filesystem: New defaults fsync_h and fdatasync_hSebastian Huber1-2/+2
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.
2012-03-13Filesystem: Reference counting for locationsSebastian Huber1-6/+2
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.
2012-02-02Removed fpathconf file system node handler.Sebastian Huber1-1/+0
There existed no calling function for this handler.

2008-05-27Added const qualifier to various pointers and data tables toThomas Doerfler1-1/+1
reduce size of data area. IMFS: Fixed creation of symbolic links to avoid a compiler warning. DOSFS: Use LibBlock instead of read() to read the boot record.

2000-06-30Patch from Chris Johns <cjohns@cybertec.com.au> to add support forJoel Sherrill1-13/+13
stat()'ing a symbolic link. This is needed to support the port of the BSD commands like ls to RTEMS.
1999-11-17Updated copyright notice.Joel Sherrill1-2/+1
1999-11-05New file.Joel Sherrill1-10/+10
1999-11-05Unmount was failing as a side-effect of splitting the rmnod handlerJoel Sherrill1-1/+1
and not handling every case properly.
1999-11-02The object memfile.o was being included in the miniIMFS even though itJoel Sherrill1-1/+1
should not have been. This required that IMFS_rmnod be split into three separate (per file type) routines to avoid dependencies. In the end, a miniIMFS application is 6K smaller than one using the full IMFS.
