* IMFS: Add fine grained configurationSebastian Huber2015-02-121-74/+0
| | | | | | | | | | | | | | | | | | Remove miniIMFS. Statically initialize the root IMFS. Add configuration options to disable individual features of the root IMFS, e.g. o CONFIGURE_IMFS_DISABLE_CHOWN, o CONFIGURE_IMFS_DISABLE_FCHMOD, o CONFIGURE_IMFS_DISABLE_LINK, o CONFIGURE_IMFS_DISABLE_MKNOD, o CONFIGURE_IMFS_DISABLE_MOUNT, o CONFIGURE_IMFS_DISABLE_READLINK, o CONFIGURE_IMFS_DISABLE_RENAME, o CONFIGURE_IMFS_DISABLE_RMNOD, o CONFIGURE_IMFS_DISABLE_SYMLINK, o CONFIGURE_IMFS_DISABLE_UNMOUNT, and o CONFIGURE_IMFS_DISABLE_UTIME.
* IMFS: Allow static initialization of FS infoSebastian Huber2015-02-121-11/+21

* IMFS: Introduce IMFS_mknod_controlSebastian Huber2015-02-121-7/+7
| | | | | | Drop IMFS_node_control::node_size field and add node_size parameter to IMFS_allocate_node() and IMFS_create_node(). This reduces the size of generic nodes.
* Filesystem: Delete unused fsmountme_h handlerSebastian Huber2015-02-091-1/+0
|
* IMFS: Reduce IMFS node typesSebastian Huber2015-01-281-3/+0
| | | | Provide only types used by IMFS_mknod().
* Filesystem: Delete node type operationSebastian Huber2015-01-221-1/+0
| | | | Use the fstat handler instead.
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-211-1/+1

* PR2160: imfs: Use ENOSYS for unsupported nodesSebastian Huber2013-12-111-3/+3
| | | | | Return an error status with errno set to ENOSYS during node creation for nodes not available in the current configuration.
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-2/+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.
* IMFS: Add and use node controlSebastian Huber2012-03-131-3/+13
| | | | | | 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.
* IMFS: Reference counting for nodesSebastian Huber2012-03-131-2/+2
| | | | | The introduction of reference counting of nodes avoids the removal of open nodes and potential usage of freed memory.
* Filesystem: Reference counting for locationsSebastian Huber2012-03-131-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
