'set_local_machine_name' so that the client can't change it from under us.
(.NET RC2 and WinXP install calls the machine 'machinename' during NTLMSSP
on the domain join).

clobbering the region, just in case clobbering causes us to crash
immediately. (That might happen if we just shot ourselves in the
stack and strcpy was not inlined.)
Also, in DEVELOPER mode and when Valgrind is available, mark the
clobbered region as uninitialized. This is an even stronger
protection than clobbering with 0xf1.

Original message:
This patch attemptes to clean up winbindd's mutex locking.
The current locking scheme in winbind is a complete mess - indeed, the
next step should be to push the locking into cli_full_connection(), but
I'll leave it for now.
This patch works on the noted behaviour that 2 parts of the connection
process need protection - and independent protection. Tim Potter did
some work on this a little while back, verifying the second case.
The two cases are:
- between connect() and first session setup
- during the auth2 phase of the netlogon pipe setup.
I've removed the counter on the lock, as I fail to see what it gains us.
This patch also adds 'anonymous fallback' to our winbindd -> DC connection.
If the authenticated connection fails (wbinfo -A specifed) - say that
account isn't trusted by a trusted DC - then we try an anonymous.
Both tpot and mbp like the patch.

This patch enables the compile-time checking of strings assable by means of
sizeof(). (Original code had the configure check reversed).
This is extended to all safe_strcpy() users, push_string and pull_string,
as well as the cli and srv derivitives. There is an attempt to cap strings
at the end of the cli buffer, and clobber_region() of the speified length
(when not -1 :-).
Becouse of the way they are declared, the 'overmalloc a string' users of
safe_strcpy() have been changed to use overmalloc_safe_strcpy() (which skips
some of the checks).
This whole ball of mud worked fine, until I pulled out my 'fix' for our
statcache. When jeremy fixes that, we should be able to get back to testing
this stuff.
This patch also includes a 'marker' of the last caller to clobber_region (ie,
the function that called pstrcpy() that called clobber_region) to assist in
debugging problems that may have smashed the stack. This is printed at
smb_panic() time. (Original idea and patch by metze).
It also removes some unsused functions, and #if 0's some others that are
unused but probably should be used in the near future.
For now, this patch gives us some confidence on one class of trivial parsing
error in our code.

lengths are correct. Attempts to pstrcpy into an fstring or allocated
string should fail in developer builds.
This builds on abartlet's earlier overflow probe for safe_strcpy, but
by clobbering the whole string with a nonzero value is more likely to
find overflows on the stack.
This is only used in -DDEVELOPER mode.
Reviewed by abartlet, tpot.

reason, during a Win2003 installation, when you select 'domain join' it sends
one machine name in the name exchange, and litraly 'machinename' during the
NTLMSSP login.
Also fix up winbindd's logfile handling, so that it matches smbd and nmbd.
(This helps me, by seperating the logs by pid).

-------------------------------------------------------------------------
I think there are basically two problem:
1. Windows clients do not always send ACEs for SMB_ACL_USER_OBJ, SMB_ACL_GROUP_OBJ,
and SMB_ACL_OTHER.
The function ensure_canon_entry_valid() is prepared for that, but tries
to "guess" values from group or other permissions, respectively, otherwise
falling back to minimum r-- for the owner. Even if the owner had full
permissions before setting ACL. This is the problem with W2k clients.
2. Function set_nt_acl() always chowns *before* attempting to set POSIX ACLs.
This is ok in a take-ownership situation, but must fail if the file is
to be given away. This is the problem with XP clients, trying to transfer
ownership of the original file to the temp file.
The problem with NT4 clients (no ACEs are transferred to the temp file, thus
are lost after moving the temp file to the original name) is a client problem.
It simply doesn't attempt to.
I have played around with that using posic_acls.c from 3.0 merged into 2.2.
As a result I can now present two patches, one for each branch. They
basically modify:
1. Interpret missing SMB_ACL_USER_OBJ, SMB_ACL_GROUP_OBJ, or SMB_ACL_OTHER
as "preserve current value" instead of attempting to build one ourself.
The original code is still in, but only as fallback in case current values
can't be retrieved.
2. Rearrange set_nt_acl() such that chown is only done before setting
ACLs if there is either no change of owning user, or change of owning
user is towards the current user. Otherwise chown is done after setting
ACLs.
It now seems to produce reasonable results. (Well, as far as it can. If
NT4 doesn't even try to transfer ACEs, only deliberate use of named default
ACEs and/or "force group" or the crystal ball can help :)

- user_ok() and user_in_group() now take a list of groups, instead of
looking for the user in the members of all groups.
- The 'server_info' returned from the authentication is now kept around
- in future we won't copy the sesion key, username etc, we will just
referece them directly.
- rhosts upgraded to use the SAM if possible, otherwise fake up based on
getpwnam().
- auth_util code to deal with groups upgraded to deal with non-winbind domain
members again.

safe_strcpy() isn't particularly safe (this has been noted before) as it does
not take the size of the buffer, but instead the size of the buffer *minus 1*
The locking.c fix was causing segfaults on machines running with
--enable-developer, and was tracked down thanks to the fact that vance's build
farm machine runs with such an option, and smbtorture's DIR1 test hits this
bug very well.
(The --enable-developer code writes to the last byte of the string, to check
for incorrect use of safe_strcpy()).
