He also suggested that some systems may implement free() as a macro (but
I think he was looking for an excuse ;). Anyway, I've added a function
to mangle.c that calls free().

proto.h: The unusual. ;)
reply.c: I changes some function names, and updated reply.c to match.
See mangle.c below for more.
server.c: Changed function names and parameters in file mangle.c, so
changed server.c calls to match. See mangle.c below for more.
mangle.c:
I replaced the caching mechanism used for caching reverse mangled name
maps. The old method was a large array of 256-byte strings. Movement
in the stack (including push and pop) was done by memcpy()ing whole
chunks of memory around.
The new system uses the ubi_Cache module which, in turn, uses a splay
tree. Entries are dynamically allocated using a minimum amount of
memory. Searches are non-linear, which should speed things up a bit,
too. Overall, this should save memory and be faster.
Other changes: I streamlined the is_mangled() test and made other
speed enhancements including replacing some static functions with
macros. Added comments, etc.
Note: Per an E'mail conversation with Andrew, the 'mangled stack'
parameter in smb.conf doesn't do anything anymore. The cache is
now set for 16K bytes maximum memory usage. The mangle stack
parameter is silently ignored. This can easily be changed, but
I'd rather introduce a 'mangled cache memory' parameter and
remove 'mangled stack'.
Remaining problems:
While testing the module, I noticed that something is calling
name_map_mangle() twice. The result is that names which contain
illegal characters are getting mangled twice.
Also, the entire module works by overwriting the input string.
This has a variety of nasty side effects.
Summary:
There's a lot still to be done, but the changes I have in place *should*
work in exactly the same way (except for the mangle stack parameter).
The rest of the bugs and other issues are separate.

algorithm was correct).
Finally (I think) fixed the mangled directory stack issue in
scan_directory() correctly. Mangled & non-mangled names are
now being checked correctly. Hurrah to Ulrik Dickow <ukd@kampsax.dk>
who helped isolate this one.

Kanji support is one case of multibyte character
support, rather than being a specific case in
single byte character support.
This allows us to add Big5 Chinese support (code page 950)
and Korean Hangul support (code page 949) at very little
cost. Also allows us to easily add future multibyte
code pages.
Makefile: Added codepages 949, 950 as we now support more multibyte
codepages.
asyncdns.c: Fixed problem with child being re-spawned when parent killed.
charcnv.c
charset.c
client.c
clitar.c
kanji.c
kanji.h
smb.h
util.c
loadparm.c: Generic multibyte codepage support (adding Big5 Chinese
and Korean Hangul).
nmbd.c: Fixed problem with child being re-spawned when parent killed.
mangle.c: Modified str_checksum so that first 15 characters have more
effect on outcome. This helps with short name mangling as
most 'long' names are still shorter than 15 chars (bug was
foobar_mng and foobar_sum would hash to the same value, with
the modified code they hash differently.

This is merely updating the Copyright statements from 1997 to 1998.
It's a once a year thing :-).
NO OTHER CHANGES WERE MADE.

mangle.c server.c proto.h
mangle.c
I am planning to replace the mangled_stack array with a proper stack,
but found many style inconsistencies (no, really). As you might expect,
I have standardized on my own preferences. ;)
I also found a potential problem in create_mangled_stack (which I've
renamed as reset_mangled_stack). If the stack size were passed into
the function as 0 or less, there was the possibility that the array
would have been freed twice. I doubt that this ever happens, but I
don't like to leave holes.
Of course, the fix will be irrelevent once I replace the array with
a linked-list-based stack.
server.c
Changed the call to create_mangled_stack() to a call to reset_mangled_stack().
proto.h
Regenerated to match the above changes. (A real comment! How unusual!)

CIFS3 spec does not list them as illegal.
This allows things like the control panel icon to be placed on a Samba
drive.

mangle.c smb.h util.c:
Big merge to allow KANJI support to be in the main
binary without explicitly compiling with it.
locking.c: Fix for smbstatus not being able to read files.
namepacket.c: Removed unneccesary debug statement.
trans2.c: Added Luke's proposed fix (ifdefed out until further testing).
nmblookup.c: Fixed bug where query fails and status is done on bogus IP.

server.c: Changed comparison from dname to name2 - seems correct - don't know why
I changed it originally. hmmmmm.
trans2.c: Made lanman2 code more similar to scan_directory(). I should
make the trans2 code call scan_dir as they are so similar.

filename problem.
Problem conditions:
case sensitive = no
default case = lower
mangle case = yes
preserve case = yes
short preserve case = yes
Problem: Win95 still writes upper case file names.
Patches supplied have been incorporated into mangle.c and server.c
but needs YOSTW to be defined for it to take effect.
Action:
=======
If we are happy with the patch, delete old code in mangle.c, then
remove all YOSTW #ifdefs.

(compiler bugs were the problem)
- minor password cleanups (catch WfWG bug where it sets the password
to a space instead of a NULL)
- fix printing problem for kanji users
- minor cleanups

Bressler)
- machten support from Trevor Strohman (trev@figment.tenon.com)
- added qinfo command to client as part of drag-and-drop printer
support for win95 from David Chappell <chappell@mouse.cc.trincoll.edu>
He also added the "printer driver" option
- use sigblock() on more systems and use sigsetmask(0) instead of
sigunblock() as its more portable. This beats a problem with zombies
on heavilily loaded systems.
- added internals.doc written by David Chappell into the source tree
- get rid of PRINT_COMMAND options from local.h as they are no longer
relevent
- new kanji code from Fujita
- don't set the recursion_available flag on queries in nmbd
- fix a potential bug with pointer subtraction in printing.c
- got rid of error_count code as the real fix (the EOF problem) is now
in
