0de01f4598 Added back groupname map stuff removed by Andrew's "slash 'n' burn"
tactics :-). Protected by #ifdef until used.

Fixed bug in fd_attempt_close() where a pointer to potentially
free'd memory was returned. I hate that.

Added "blocking locks" as a per-share option for performance testing.

Changed is_mangled() so it will return true if called with a pathname
and any component of the pathname was mangled (it was already attempting
to do this, but not checking for a '/' as end-of-mangle).

This should be a better fix for the wierd stat cache bug Andrew identified.

c319d8ea3f fixed a bug in the name mangling code. It implicitly assumed that
mangling a name can't increase it's size which isn't true. (imagine a
file called "L B" which mangles to "LB~XX")

The symptoms were that users couldn't run batch files from short
directory names that contained non 8.3 characters (such as spaces).

c7ee025ead this is the bug change to using connection_struct* instead of cnum.
Connections[] is now a local array in server.c

I might have broken something with this change. In particular the
oplock code is suspect and some .dll files aren't being oplocked when
I expected them to be. I'll look at it after I've got some sleep.

899d0d5de5 Noticed that I was using the strlen() of a string that I had strdup()'d
before testing that the strdup() worked.  Fixed.

a1f4c8567c I've put the ubiqx headers back into includes.h, and removed them from
dir.c & mangle.c.  This was possible after I checked the tree code to make
sure that the tree code did not reference functions by macro name.  Also,
note that the AVL module has been removed to prevent conflict with the
SplayTree macro defines.

2d77445400 This is a security audit change of the main source.
It removed all ocurrences of the following functions :

sprintf
strcpy
strcat

The replacements are slprintf, safe_strcpy and safe_strcat.

It should not be possible to use code in Samba that uses
sprintf, strcpy or strcat, only the safe_equivalents.

Once Andrew has fixed the slprintf implementation then
this code will be moved back to the 1.9.18 code stream.

95f7b03285 Andrew redefines the free() function to do some memory management testing.
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().

8759bec11b Changes include:
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.

37f5f7b557 Removed broken change I made to mangle.c (ooops. Andrew's original
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.

299016338c Change the multibyte character set support so that
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.

b9c1697723 This is *not* a big change (although it looks like one).
This is merely updating the Copyright statements from 1997 to 1998.
It's a once a year thing :-).
NO OTHER CHANGES WERE MADE.

34d1b3e4fa Modified Files:
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!)

d2ac9e6fb6 remove { and } from the list of illegal characters in filenames. The
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.

84fc674c89 JHT ===> William Yost patches integrated to fix leading path on 8.3
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.

92566ecc31 - replace the base36 function with one that works on more systems
(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

aa6f8b04d1 - sequent-ptx support from bressler@iftccu.ca.boeing.com (Rick
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
