2023-05-20Update company nameSebastian Huber
The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
2022-03-22cpukit/libfs/src/imfs: Change license to BSD-2Joel Sherrill
Updates #3053.
2020-04-28doxygen: Switch @brief and @ingroupSebastian Huber
This order change fixes the Latex documentation build via Doxygen.
2020-04-16Canonicalize config.h includeSebastian Huber
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2017-12-13IMFS: Include <rtems/imfs.h>Sebastian Huber
Prepare for header file move to common include directory. Update #3254.
2015-02-15IMFS: Implement variable length node namesSebastian Huber
This reduces the average node size and adds more flexibility.
2015-01-27IMFS: Replace node union with individual structSebastian Huber
This reduces the average node size. Add and use IMFS_GENERIC_INITIALIZER().

2014-01-21IMFS: Improved support for generic nodesSebastian Huber
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.

2012-12-18libfs: Doxygen Enhancement Task #2Alex Ivanov
http://www.google-melange.com/gci/task/view/google/gci2012/8032207
2012-03-13IMFS: Add and use node controlSebastian Huber
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.
2012-03-13IMFS: New support functionsSebastian Huber
Add and use IMFS_type() and IMFS_is_directory().
2012-03-13IMFS: Reference counting for nodesSebastian Huber
The introduction of reference counting of nodes avoids the removal of open nodes and potential usage of freed memory.
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: 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.

1999-11-17Updated copyright notice.Joel Sherrill
1999-11-05Unmount was failing as a side-effect of splitting the rmnod handlerJoel Sherrill
and not handling every case properly.
1999-10-26Added initial cut at miniIMFS which leaves out memfile and directoryJoel Sherrill
readdir support. The next step is to add a mount table and configure either the miniIMFS or the full IMFS at the application level.
1999-10-12Split null handlers table to own file and renamed.Joel Sherrill
Renamed IMFS handler tables to include IMFS prefix.
1999-02-24Changed IMFS to use IMFS_NAME_MAX as the maximum length of a basenameJoel Sherrill
rather then NAME_MAX. NAME_MAX is 255 and that lets IMFS chew up memory too fast. Perhaps in the future, the places in IMFS that put a maximum length name string on the stack and the jnode structure does not include a maximu length name string can be fixed so this is not a problem.
1999-02-05Corrected spacing and added some new error checks that were neededJoel Sherrill
to avoid dereferencing NULLs.
1998-11-23Added base version of file system infrastructure. This includes a majorJoel Sherrill
overhaul of the RTEMS system call interface. This base file system is the "In-Memory File System" aka IMFS. The design and implementation was done by the following people: + Joel Sherrill (joel@OARcorp.com) + Jennifer Averett (jennifer@OARcorp.com) + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com) + Kerwin Wade (wade@OARcorp.com) PROBLEMS ======== + It is VERY likely that merging this will break the UNIX port. This can/will be fixed. + There is likely some reentrancy/mutual exclusion needed. + Eventually, there should be a "mini-IMFS" description table to eliminate links, symlinks, etc to save memory. All you need to have "classic RTEMS" functionality is technically directories and device IO. All the rest could be left out to save memory.
