Update #3894.
|
|
The CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK value is validated by
<rtems/confdefs/libio.h>. Changing this value during runtime could lead
to memory corruption.

Remove IMFS_NODE_FLAG_NAME_ALLOCATED and instead replace the node
control in rename operations. This avoids a special case in the general
node destruction which pulled in free().

Fix prototype.
Fix node size. Linfiles are dynamically turned into memfiles.

A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.

Added a mmap file handler to struct _rtems_filesystem_file_handlers_r.
Updated each file handler object to support the default mmap handler.
Updated mmap() to call the mmap handler for MAP_SHARED.
Added a mmap file handler for shm
Added support for MAP_ANON in mmap().

This helps to use IMFS_make_generic_node() without pulling in the
complete IMFS implementation.
|
|
Use the adjusted and not the requested memfile bytes per block.
Untangle dependencies.
|
|
The permission is check by the upper layer.

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.

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.

This reduces the average node size and adds more flexibility.

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.

Fix memory leak in IMFS_fsunmount().
|
|
|
|
Make several functions static.
|
|
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.
|
|
|
|
The type of ino_t is unsigned long, so it can store a pointer. Avoid a
potential integer overflow.
|
|
|
|
Provide only types used by IMFS_mknod().
|
|
|
|
This reduces the average node size.
Add and use IMFS_GENERIC_INITIALIZER().
|
|
Use the fstat handler instead.

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.
