* Filesystem: Reject removal of root nodesSebastian Huber2012-10-075-16/+8
| | | | | | | 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.
* IMFS: TypoSebastian Huber2012-08-091-1/+1

* Filesystem: Change pathconf_limits_and_optionsSebastian Huber2012-05-151-1/+1
| | | | | | The pathconf_limits_and_options field of rtems_filesystem_mount_table_entry_t is now a const pointer to reduce the read-write memory demands of file system instances.
* Filesystem: Move operations to mount table entrySebastian Huber2012-05-152-2/+6
| | | | | | | | | | | 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.
* Filesystem: PR1255: Move offset update to handlersSebastian Huber2012-05-151-1/+10
| | | | | | | It is now the responsibility of the read() and write() handler to update the offset field of the IO descriptor (rtems_libio_t). This change makes it possible to protect the IO descriptor from concurrent access by per file locks.
* Filesystem: Add shared device IO supportSebastian Huber2012-05-152-186/+26
| | | | | The device IO file system support in IMFS, devFS, and RFS uses now a shared implementation.
* Filesystem: Use ioctl_command_tSebastian Huber2012-05-155-32/+10

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-1132-64/+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: PR1893: Fix write and truncate handlerSebastian Huber2012-05-111-3/+18
| | | | | Space that grows due to truncate or write offsets beyond the current file size must be zero filled.
* Filesystem: PR1871: Fix O_APPENDSebastian Huber2012-05-111-3/+4
|
* Filesystem: PR1398: Fix lseek() mechanicSebastian Huber2012-05-117-109/+5
| | | | | | | | | | | | According to POSIX the lseek() function shall not, by itself, extend the size of a file. Remove the size field of rtems_libio_t. A file has only one size but may have multiple open file descriptors. Thus a file size field in the file descriptor may lead to inconsistencies. New default handlers rtems_filesystem_default_lseek_file() and rtems_filesystem_default_lseek_directory().
* Filesystem: Remove pipe_lseek()Sebastian Huber2012-05-041-11/+1

* IMFS: Update IMS_assert check when RTEMS_DEBUG is enabled.Chris Johns2012-04-281-1/+1
| | | | Update the assert macro to the new IMFS_jnode_t.
* IMFS: Node specific stat handlersSebastian Huber2012-03-135-58/+81
|
* IMFS: Generic device identifierSebastian Huber2012-03-131-0/+12
|
* IMFS: Add make generic node supportSebastian Huber2012-03-132-0/+154
| | | | | | | | | | | | | | | | | | | | | | Generic nodes are an alternative to standard drivers in RTEMS. The handlers of a generic node are called with less overhead compared to the standard driver operations. The usage of file system node handlers enable more features like support for fsync() and fdatasync(). The generic nodes use the reference counting of the IMFS. This provides automatic node destruction when the last reference vanishes. Extend type IMFS_types_union by new type IMFS_generic_t. Extend enum IMFS_jnode_types_t by IMFS_GENERIC. Add functions o IMFS_make_generic_node(), o IMFS_is_imfs_instance(), o IMFS_generic_get_context_by_node(), o IMFS_generic_get_context_by_location(), and o IMFS_generic_get_context_by_iop(). New test fstests/fsimfsgeneric01.
* IMFS: Add and use node controlSebastian Huber2012-03-1314-315/+419
| | | | | | 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: New support functionsSebastian Huber2012-03-139-31/+43
| | | | Add and use IMFS_type() and IMFS_is_directory().
* IMFS: Removed superfluous imfs_dir_open()Sebastian Huber2012-03-133-35/+1
|
* IMFS: Reference counting for nodesSebastian Huber2012-03-1316-126/+84
| | | | | The introduction of reference counting of nodes avoids the removal of open nodes and potential usage of freed memory.
* IMFS: Use unprotected chain operationsSebastian Huber2012-03-134-17/+28
| | | | | Directory entry add or removal operations are protected by the file system instance lock. There is no need for protected chain operations.
* IMFS: Lock the file system during directory readsSebastian Huber2012-03-131-21/+15
| | | | | Other threads may add or remove directory entries during a read of the directory. Use the file system instance lock for protection.
* IMFS: Do not check for unsupported typesSebastian Huber2012-03-131-10/+0
| | | | | Allow creation of nodes with an unsupported type. Later the usage of such nodes will return an error status.
* Filesystem: Rename definesSebastian Huber2012-03-132-6/+6
| | | | | | | | | | | | | | | o Removed RTEMS_LIBIO_PERMS_SEARCH. o Renamed RTEMS_LIBIO_PERMS_READ in RTEMS_FS_PERMS_READ. o Renamed RTEMS_LIBIO_PERMS_WRITE in RTEMS_FS_PERMS_WRITE. o Renamed RTEMS_LIBIO_PERMS_EXEC in RTEMS_FS_PERMS_EXEC. o Renamed RTEMS_LIBIO_FOLLOW_HARD_LINK in RTEMS_FS_FOLLOW_HARD_LINK. o Renamed RTEMS_LIBIO_FOLLOW_SYM_LINK in RTEMS_FS_FOLLOW_SYM_LINK. o Renamed RTEMS_LIBIO_MAKE in RTEMS_FS_MAKE. o Renamed RTEMS_LIBIO_EXCLUSIVE in RTEMS_FS_EXCLUSIVE. o Renamed RTEMS_LIBIO_ACCEPT_RESIDUAL_DELIMITERS in RTEMS_FS_ACCEPT_RESIDUAL_DELIMITERS. o Renamed RTEMS_LIBIO_REJECT_TERMINAL_DOT in RTEMS_FS_REJECT_TERMINAL_DOT.
* Filesystem: New defaults fsync_h and fdatasync_hSebastian Huber2012-03-137-43/+10
| | | | | | | 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.
* Filesystem: Reference counting for locationsSebastian Huber2012-03-1335-1610/+635
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
