2015-06-19nfsclient: Use an interrupt lockSebastian Huber
2015-02-09Filesystem: Delete unused fsmountme_h handlerSebastian Huber
2015-01-22Filesystem: Delete node type operationSebastian Huber
Use the fstat handler instead.
2013-12-20Filesystem: Use default kqfilter and poll handlerSebastian Huber
2013-12-20Filesystem: Add readv/writev handlersSebastian Huber
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.
2013-01-09nfsclient: Return an error status in nfsInit()Sebastian Huber
Avoid assert() and use proper cleanup if nfsInit() fails to allocate a resource.
2012-12-28libfs: Doxygen Enhancement Task #5Mathew Kallada
2012-10-02nfsclient: Add and use nfsEvaluateStatus()Sebastian Huber
The NFS status codes do not map directly to the corresponding errno values.
2012-10-02nfsclient: PR2075: Fix node initializationSebastian Huber
2012-05-16nfsclient: Fix symbolic link evaluationSebastian Huber
2012-05-15Filesystem: Change pathconf_limits_and_optionsSebastian Huber
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.
2012-05-15Filesystem: Move operations to mount table entrySebastian Huber
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.
2012-05-15Filesystem: Add const qualifier to lock/unlockSebastian Huber
2012-05-15Filesystem: PR1255: Move offset update to handlersSebastian Huber
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.
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill
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.
2012-05-11Filesystem: PR1398: Fix lseek() mechanicSebastian Huber
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().
2012-05-04nfsclient: Add rename operationSebastian Huber
2012-05-04nfsclient: Fix hard link operationSebastian Huber
2012-05-04Filesystem: Use proper parameter in NFSSebastian Huber
2012-04-23nfsclient: Use UID and GID of NFS handleSebastian Huber
Use UID and GID of the NFS handle for node and symbolic link creation.
2012-04-23nfsclient: POSIX conformanceSebastian Huber
According to POSIX the read() call should return the maximum number of bytes available for regular files.
2012-03-13Filesystem: Rename definesSebastian Huber
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.
2012-03-13Filesystem: New defaults fsync_h and fdatasync_hSebastian Huber
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 Huber
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 Huber
There existed no calling function for this handler.
