* untar: do not exit with error when created directory already exists.Pavel Pisa2015-11-231-1/+17
| | | | | | | | | | | | | | The problem exists for both RTEMS untar implementations and their variants: Untar_FromMemory(), Untar_FromFile() and rtems_tarfs_load(). If filesystem object already exists at extracted directory path then if it is directory, creation is ignored. Attempt to delete/unlink object and make directory is tried for other cases. This simple approach problem reported in ticket fixes #2413. Behavior follows GNU tar and BSD tar practice for directories but much more work is required to achieve full semantics of the full featured tar implementation still.

* IMFS: don't strlen() an unterminated string in IMFS_dir_read().Jamie Iles2015-03-161-1/+1
| | | | | | | | | a43a3466 (IMFS: Implement variable length node names) introduced a changed to IMFS_jnode_t from being a null terminated string to a separate unterminated string and length. IMFS_dir_read() was still performing a strlen() on this unterminated string though and when doing an 'ls' in the fileio example I saw that some filenames had garbage suffixes.

* IMFS: Add fine grained configurationSebastian Huber2015-02-126-183/+7
| | | | | | | | | | | | | | | | | | 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.

| | | | Make several functions static.
* IMFS: Introduce IMFS_mknod_controlSebastian Huber2015-02-1216-76/+94
| | | | | | 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.

* IMFS: Simplify ino generationSebastian Huber2015-02-044-5/+7
| | | | | The type of ino_t is unsigned long, so it can store a pointer. Avoid a potential integer overflow.

* IMFS: Replace node union with individual structSebastian Huber2015-01-2722-595/+511
| | | | | | This reduces the average node size. Add and use IMFS_GENERIC_INITIALIZER().

* imfs/imfs_handlers_link.c: Add _Assert for NULL pointerJosh Oguin2014-11-261-0/+2
| | | | | CodeSonar flagged this as a possible dereference of a NULL pointer. This should never occur so adding _Assert().

| | | | Include <sys/param.h> if necessary to get the MIN()/MAX() macros.

* IMFS: Improved support for generic nodesSebastian Huber2014-01-212-3/+3
| | | | | | | | | | | | | | | | The rtems_filesystem_location_info_t::node_access_2 was unused by the IMFS. Use it to hold the context of generic nodes. This makes it possible to use node handlers for objects with and without a corresponding file system node. For example network sockets created with socket() have only a file descriptor, but no corresponding file system node. The UNIX(4) domain sockets can be bound to file system nodes. In both cases the rtems_filesystem_location_info_t must provide a pointer to the socket structure used by the socket node handlers. With the context pointer (for sockets, this is the socket structure) in rtems_filesystem_location_info_t::node_access_2 the same node handlers can be used in both cases.

* Filesystem: Use default kqfilter and poll handlerSebastian Huber2013-12-205-0/+10
|
* Filesystem: Add readv/writev handlersSebastian Huber2013-12-205-55/+65
| | | | | | | | | 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.
* PR2160: imfs: Use ENOSYS for unsupported nodesSebastian Huber2013-12-114-7/+18
| | | | | Return an error status with errno set to ENOSYS during node creation for nodes not available in the current configuration.
* libfs/imfs: Set the FIFO control block.Chris Johns2013-12-101-1/+1
| | | | The FIFO was incorrectly set to the default control block.
* IMFS: Use IMFS_mtime_ctime_update()Sebastian Huber2013-10-272-4/+2

* IMFS: Fix truncate according to POSIXSebastian Huber2013-09-131-3/+2
| | | | | | | | | | | | | | | | | ftruncate() and open() with O_TRUNC shall upon successful completion mark for update the st_ctime and st_mtime fields of the file. truncate() shall upon successful completion, if the file size is changed, mark for update the st_ctime and st_mtime fields of the file. The POSIX standard "The Open Group Base Specifications Issue 7", IEEE Std 1003.1, 2013 Edition says nothing about the behaviour of truncate() if the file size remains unchanged. Future directions of the standard may mandate the behaviour specified in ftruncate(): http://austingroupbugs.net/view.php?id=489
