* Canonicalize config.h includeSebastian Huber2020-04-161-2/+2
| | | | | | | | Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-211-1/+1

* statvfs and ALL filesystem handlers: Add restrict keyword.Daniel Ramirez2013-11-211-1/+1

* Filesystem: Move operations to mount table entrySebastian Huber2012-05-151-1/+1
| | | | | | | | | | | 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.
* 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.
* Filesystem: Rename definesSebastian Huber2012-03-131-1/+1

* Filesystem: Reference counting for locationsSebastian Huber2012-03-131-27/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 2009-10-08 Chris Johns <chrisj@rtems.org>Chris Johns2009-10-081-0/+60
* Makefile.am, preinstall.am: Added statvfs.h. * libcsupport/Makefile.am: Add statvfs.c. * libcsupport/include/sys/statvfs.h, libcsupport/src/statvfs.c: New. * libcsupport/include/rtems/libio.h: Add a file system handler for the statvfs call. * libfs/src/devfs/devfs_init.c, libfs/src/dosfs/msdos_init.c, libfs/src/imfs/imfs_init.c, libfs/src/nfsclient/src/nfs.c: Set the statvfs handler to NULL. * include/rtems/fs.h: Add a second node access field for the RFS file system to hold a directory offset while the existing field holds the inode number. This save a rescan of the directory when working with directories. * libblock/include/rtems/bdbuf.h: Added references and user fields to the buffer descriptor. * libblock/src/bdbuf.c: Added dynamic buffer support for different block sizes. Fixed a number of bugs. * libblock/src/blkdev.c: Release the disk device on an error. * libblock/src/diskdevs.c: Set the block size to the media block size during initialisation of the disk device. * libblock/src/flashdisk.c, libblock/src/nvdisk.c, libblock/src/ramdisk.c: Updated the drivers to handle variable block sizes. * libfs/src/dosfs/fat.c, libfs/src/dosfs/fat.h: Release any buffers when an error occurs. The FAT buffer layer hangs onto a single buffer while mounted. This should be fixed. * sapi/inline/rtems/chain.inl: Added rtems_chain_set_off_chain, rtems_chain_is_node_off_chain, and rtems_chain_previous. * score/inline/rtems/score/chain.inl: Added _Chain_Set_off_chain, and _Chain_Is_node_off_chain. * libmisc/shell/main_ln.c, libmisc/shell/main_mknod.c, libmisc/shell/mknod-pack_dev.c, libmisc/shell/mknod-pack_dev.h: New shell commands. * libmisc/Makefile.am, libmisc/shell/shellconfig.h: Added ln and mknod commands. * libmisc/shell/hexdump-display.c: Fixed the reopen bug which showed up as a free with a bad pointer. * libmisc/shell/main_mount.c: List the user adding file system when listing the available file systems to mount. * libmisc/shell/utils-cp.c: Remove the fixed static copy buffer and use a large dynamic buffer. * score/inline/rtems/score/address.inl, score/src/coremsgsubmit.c, score/src/objectallocate.c, score/src/objectfree.c: Remove warnings.
