This is a small (21K on sparc) editor that provides some powerful
features useful when a file needs editing on an embedded
board. No need to copy files off, edit, copy back.
The ping code is taken from a recent FreeBSD release. Some options have been
tested, other not tested or do not work. This could be due to the age of
our TCP/IP stack.
This version of ping will not work if more than 64 file descriptors are
open at once because the select FD size is 64 as set in newlib.
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.
* libmisc/shell/main_mdump.c: Reworked to fix bugs in handling of the
length argument and to provide an "ldump" command. This file now also

libmisc/shell/shellconfig.h: Split malloc.c into multiple files with
one function per file. Also split out statistics into a separate file
which can be plugged in dynamically. Right now, it is always in. I
suspect that splitting the file removed more code than leaving
statistics in. I tinkered with malloc information command in the
shell. I resurrected the malloc arena code as malloc boundary. This
code is now compiled all the time even though it does not appear to
work.

applications. The is an RTEMS shell after all.
* libmisc/shell/shell.h, libmisc/shell/internal.h,
libmisc/shell/shellconfig.h: Move all shell_* types, variables and
functions to rtems_shell_* to avoid namespace clashes with
applications. Add the mount command supporting types.

libmisc/shell/shell.c, libmisc/shell/shell.h: Split shell commands
into multiple files and add initial stages of command configuration.
This seems to work but the monitor commands need to be integrated
this way and the ability to configure user commands needs to be
tested.
