* libc/termios.c: Fixed a memory leak in the termios
software. Basically the tty open function was allocating an input
raw buffer, an output raw buffer, and a cooked buffer that were
not getting released. I have attached a patch for the latest
snapshot. The patch also has a fix to ensure the tty link list
is updated correctly when a tty is closed.
* include/rtems/libio_.h: Added ifdef to ensure that LOGIN_NAME_MAX
is defined on GNU/Linux (RedHat 6.2 distribution).
* libc/unixlibc.c: Added stubs for rtems_io_register_name() and
rtems_io_lookup_name() so UNIX port would compile the IO manager
sptest that registers /dev/null.
* libc/lseek.c: Modified after discussion with Eugeny S. Mints
<jack@oktet.ru> to correct the behavior. There were two mistakes.
First, iop->offset was incorrectly set for SEEK_END. Second,
iop->offset should be left unmodified if there are errors.
This modification attempts to fix both situations.

* libc/termios.c: Fix a bug in the termios implementation in
the following scenario:
The General Terminal Interface document that me states that
if VMIN = 0 and VTIME = 0, then read() should return the minimum
of two values:
a) number of bytes available
b) number of bytes requested (I assume from the read call)
The current implementation of the fillBufferQueue() in termios.c is
always return 1 character with these setting values. I know the
termios buffer has more than one character available and my read()
call is requesting 1024 bytes.

* libc/libio_sockets.c (rtems_bsdnet_fdToSocket): Per bug
report from Gene Smith <Gene.Smith@sea.siemens.com>, enhanced the
error checking to account for a socket being closed.
* libc/base_fs.c: Deleted chmod() now that IMFS creates the
root node with the desired permissions. chmod() is also not
supported by the miniIMFS so this is not allowable.
* libc/ttyname.c (ttyname_r): Removed duplicate call to closedir().
* libc/getpwent.c: Create a more robust /etc/passwd and /etc/group.
* libc/base_fs.c: Change permissions of files and directories. Now uses
octal constants.
* libc/libio.c (rtems_libio_allocate): Make sure size and offset
fields are cleared on each file open. Before this field was cleared,
this resulted in the value from the last time that IOP was used
being still in place. Discovered by Andrew Bythell
<abythell@nortelnetworks.com>.
* libc/open.c: Remove redundant setting of iop->offset.
* include/rtems/libio_.h, libc/chroot.c, libc/privateenv.c:
Private environment and chroot() enhancements and fixes. Comments:
+ privateenv has been modified to let at chroot() to be more
POSIX like Sergei Organov recommended.
+ A task owner lets that rtems_set_private_env() will be
called twice or more times.
+ chroot() can be called without a previous
rtems_set_private_env(); (transpanrently)
+ The second call of rtems_set_private_env() makes a internal
chroot("/") into global imfs_root.
+ chroot() runs like chdir() without a previous chdir("/") with
the global root.
+ The current directory can be in a wrong place like Linux and
many other Unices.
* cpu.c, rtems/score/cpu.h: Bug report from Peter Mueller
<peter.o.mueller@gmx.de> because of not correcting for the ISR
vector table now being allocated from the workspace.
* Alternate email is correo@fernando-ruiz.com
* libc/privateenv.c: New file.
* include/rtems/libio_.h, libc/Makefile.am, libc/base_fs.c,
libc/unmount.c: Moved default umask, current working directory,
root, and links followed count into a structure "user environment"
that can then be treated as a unit. This enable giving unique
copies of these to individual threads or collection of threads.
* include/rtems/Makefile.am: Added termiostypes.h.
* libc/Makefile.am: Removed termiostypes.h.
* libc/termios.c: Changed include of "termiostypes.h" to
<rtems/termiostypes.h> since that is an RTEMS specific header file.
* libc/mount.c (search_mt_for_mount_point): Deleted routine.
* libc/mount.c (Is_node_fs_root): Replacement for above that
accounts for the imaginary root node being returned by the
filesystem evaluation routine.
* libc/unmount.c (unmount): Account for imaginary root node
being returned and improved variable names to clarify code.
* libc/unmount.c (file_systems_below_this_mountpoint): Body of
routine replaced to account for imaginary root node being returned.
* libc/ioman.c: Moved to libfs.
* libc/Makefile.am: Removed ioman.c as part of moving it to libfs.
* libc/base_fs.c: Removed include of imfs.h and reworded comment
to avoid being IMFS specific.
* libc/libio.h: Removed prototype of IMFS_ops since it should
not be in this file.
* libc/mount.c: Removed IMFS specific configuration information.
* libc/unmount.c: Removed include of imfs.h and reworded comment
to avoid being IMFS specific.
* libc/Makefile.am: Added mallocfreespace.c.
* libc/mallocfreespace.c: New file based on work by Nick Simon
<Nick.SIMON@syntegra.bt.co.uk> which he included in malloc.c.
* libc/libcsupport.h: Added prototype for malloc_free_space().
* libc/fcntl.c: Do not require every filesystem to have an fcntl()
handler. Most fcntl() operations can be performed with no
filesystem support.
* ChangeLog: Corrected comment.
the correct circumstances of DMA buffer size, serial
line interrupts, and ethernet interrupts the termios osend routine would
lock up waiting for the raw output buffer semaphore.
a BSP (c4xsim) supporting the simulator included with gdb. This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.
An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU. This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.
now is an implementation of the prototypes in rtems/rtems/cache.h.
The libcpu/i386/wrapup directory is no longer needed.
The PowerPC needs this done to it.
<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart
<Darlene.Stewart@nrc.ca> to add support for a number of very
significant things:
+ BSPs for many variations on the Motorola MBX8xx board series
+ Cache Manager including initial support for m68040
and PowerPC
+ Rework of mpc8xx libcpu code so all mpc8xx CPUs now use
same code base.
+ Rework of eth_comm BSP to utiltize above.
John reports this works on the 821 and 860
