now in pipe struct (where used) rather than user_struct.
Secured machine account password changing in srv_netlog_nt.c - ensure
that only the given machine can change its own password. May need to
free this up later for NT admin tools, but this is a fail-safe secure
position for now.

include/smb.h: Added LPQ_xx enums to correspond with the NT JOB_STATUS_XXX. We
need these to be different as we're storing LPQ_xx enums in the tdb
already.
rpc_server/srv_spoolss_nt.c: Don't need to return status strings as we're now
returning status codes.
smbd/lanman.c: Change the RAP status codes to have "RAP" in the name.
printing/printing.c: Keep track of the status of a job. Allow a job to be
deleted from one smbd when being submitted by another.
Made logic in mutex clearer.
Jeremy.
source/rpc_server/srv_spoolss_nt.c
- add an access check to _spoolss_deleteprinter() to stop random
users and passers by from deleting printers.
source/lib/messages.c
- converted global msg_all struct to a local in message_send_all()
function.
source/include/smb.h
- added a success error code to the spoolss return codes.
source/include/proto.h
source/param/loadparm.c
source/printing/printing.c
- Added new parameter "total print jobs" to limit the total number
of print jobs across all queues. Currently individual queues are
limited by "max print jobs".
list of structures rather than the dodgy parsing code we had before
this also gets smbw working correctly with no initial workgroup (using
name_status_find on __MSBROWSE__ returns)
Currently does exactly the same thing (returns ACLs the same way). This
code is written to try and get a POSIX ACL via the abstract sys_XX interface,
then fall back to providing a UNIX based ACL if the calls fail. Seems to
work. Next step is to add a --with-posix-acls to configure.in and then
check on a POSIX ACL system that a complex ACL is returned correctly
as an NT ACL. Note that the ACL set (a more complex problem) is not
addressed yet.

statement after an 'if'. Tracking this down took 4 hours from my life and ANDREW I WANT
THEM BACK !!!!! :-).
include/smb.h smbd/password.c: Fixed the bug veritas reported with realloc of the validated_users
array growing without bounds. This is now a linked list as god (Andrew) intended :-).
Jeremy.
o added BOOL own_memory flag in SAM_ACCOUNT so we could
use static memory for string pointer assignment or
allocate a new string
o added a reference TDB passdb backend. This is only a reference
and should not be used in production because
- RID's are generated using the same algorithm as with smbpasswd
- a TDB can only have one key (w/o getting into problems) and we
need three. Therefore the pdb_sam-getpwuid() and
pdb_getsampwrid() functions are interative searches :-(
we need transaction support, multiple indexes, and a nice open
source DBM. The Berkeley DB (from sleepycat.com seems to fit
this criteria now)
o added a new parameter "private dir" as many places in the code were
using lp_smb_passwd_file() and chopping off the filename part.
This makes more sense to me and I will docuement it in the man pages
o Ran through Insure-lite and corrected memory leaks. Need for
a public flogging this time Jeremy (-:

- merged Tim's vlp (virtual lp) test program. Enable it with
-DDEVELOPER or by using ./configure.developer
(source/include/smb.h source/configure.developer
source/printing/lpq_parse.c source/param/loadparm.c
testsuite/printing/.cvsignore testsuite/printing/Makefile.vlp
testsuite/printing/vlp.c)
Currently the only backend which works is smbpasswd (tdb, LDAP, and NIS+)
are broken, but they were somewhat broken before. :)
The following functions implement the storage manipulation interface
/*The following definitions come from passdb/pdb_smbpasswd.c */
BOOL pdb_setsampwent (BOOL update);
void pdb_endsampwent (void);
SAM_ACCOUNT* pdb_getsampwent (void);
SAM_ACCOUNT* pdb_getsampwnam (char *username);
SAM_ACCOUNT* pdb_getsampwuid (uid_t uid);
SAM_ACCOUNT* pdb_getsampwrid (uint32 rid);
BOOL pdb_add_sam_account (SAM_ACCOUNT *sampass);
BOOL pdb_update_sam_account (SAM_ACCOUNT *sampass, BOOL override);
BOOL pdb_delete_sam_account (char* username);
There is also a host of pdb_set..() and pdb_get..() functions for
manipulating SAM_ACCOUNT struct members. Note that the struct
passdb_ops {} has gone away. Also notice that struct smb_passwd
(formally in smb.h) has been moved to passdb/pdb_smbpasswd.c
and is not accessed outisde of static internal functions in this
file. All local password searches should make use of the the SAM_ACCOUNT
struct and the previously mentioned functions.
I'll write some documentation for this later. The next step is to fix
the TDB passdb backend, then work on spliting the backends out into
share libraries, and finally get the LDAP backend going.
What works and may not:
o domain logons from Win9x works
o domain logons from WinNT 4 works
o user and group enumeration
as implemented by Tim works
o file and print access works
o changing password from
Win9x & NT ummm...i'll fix this tonight :)
If I broke anything else, just yell and I'll fix it. I think it
should be fairly quite.

a conn struct depending on the call.
We need this to have a clean NT ACL call interface.
This will break any existing VFS libraries (that's why this is pre-release
code).
Andrew gets credit for this one :-) :-).
In addition - added Herb's WITH_PROFILE changes - Herb - please examine
the changes I've made to the smbd/reply.c code you added. The original
code was very ugly and I have replaced it with a
START_PROFILE(x)/END_PROFILE(x) pair using the preprocessor.
Please check this compiles ok with the --with-profile switch.
Jeremy.
with the current user. This will allow se_access_check() to quickly do
a SD check without having to translate uid/gid's to SIDs.
Still needs work on pipe calls.
Jeremy.
get ready and fix se_access_check().
Added cannonical lookup_name(), lookup_sid(), uid_to_sid(), gid_to_sid()
functions that look via winbind first the fall back on local lookup.
All Samba should use these rather than trying to call winbindd code
directly.
Added NT_USER_TOKEN struct in user_struct, contains list of NT sids
associated with this user.
se_access_check() should use this (cached) value rather than attempting
to do the same thing itself when given a uid/gid pair.
More work needs to be done to preserve these things accross security
context changes (especially with the tricky pipe problem) but I'm
beginning to see how this will be done..... probably by registering
a new vuid for an authenticated RPC pipe and not treating the
pipe calls specially.
More thoughts needed - but we're almost there...
Jeremy.
- changed the default forms flag to 2
- all short architecture name are uppercased
- get_short_archi() is now case unsensitive
- the drivers TDB is indexed by archi/version/name
- implemented code to move drivers from the upload area to the download
area. Someone else need to look at that code.
- don't return anymore a default driver if it doesn't exist in the TDB.
Instead return an error.
- cleaned prs_unistr.
- #ifdef out jeremy's new SD parsing in printer_info_2
- removed the unused MANGLE_CODE
- #ifdef out the security checking in update_printer() as it doesn't work
for me.
Zap your ntdrivers.tdb, it won't work anymore.
J.F.
semi-connection and a rpcclient prompt, but no functionality there yet.
Will be a few more days on that.
The changes to the header files were minor. A few struct's and a few
additional fields to existing ones. No deletions. **minimal change
necessary** :-) Well, maybe not minimal, but I tried.
All other programs compile, link and run ok from what I can tell so
I don;t think I broke anything.

handling in Samba. This was needed due to several limitations and
races in the previous code - as a side effect the new code is much
cleaner :)
in summary:
- changed sys_select() to avoid a signal/select race condition. It is a
rare race but once we have signals doing notification and oplocks it
is important.
- changed our main processing loop to take advantage of the new
sys_select semantics
- split the notify code into implementaion dependent and general
parts. Added the following structure that defines an implementation:
struct cnotify_fns {
void * (*register_notify)(connection_struct *conn, char *path, uint32 flags);
BOOL (*check_notify)(connection_struct *conn, uint16 vuid, char *path, uint32 flags, void *data, time_t t);
void (*remove_notify)(void *data);
};
then I wrote two implementations, one using hash/poll (like our old
code) and the other using the new Linux kernel change notify. It
should be easy to add other change notify implementations by creating
a sructure of the above type.
- fixed a bug in change notify where we were returning the wrong error
code.
- rewrote the core change notify code to be much simpler
- moved to real-time signals for leases and change notify
Amazingly, it all seems to work. I was very surprised!
place to do this, not in smbd/passwd.c
Please don't change this without asking first, I have run this past
Andrew so talk to him (I'm on vacation next week).
I also removed the g_newXXX macros. There are essentially a private C extension,
not used anywhere else in the code, and add no functionality over malloc(XX)
and make the code harder to understand (everyone knows what malloc does).
Jeremy.
as there is no infrastructure for it. Replaced it with a dynamic array
of group SIDs plus a user.
passdb/passdb.c: Added setup_user_sids() function. This is where the lookup should be done,
eventually calling winbind.
smbd/password.c: Changed to call setup_user_sids(). Removed spurious DEBUG(0) statements.
smbd/reply.c: Removed extra parameter to register_vuid().
Jeremy.
userdom_struct. As the name implies this also contains a domain
(unused at the moment).
This will be important shortly, as operation in appliance mode needs
the domain to be always carried with the username.
This implementation keeps all POSIX lock records in a separate in memory
tdb database only known about in locking/posix.c. In addition, the pending
close fd's are also held in a tdb which has an array of fd's indexed by
device and inode.
The walk-split code uglyness has been moved to posix.c from brlock.c,
which is the only place that needs to know about it, and the extra
functions hacked into brlock to expose internal state have been removed.
This implementation passes smbtorture locktest4, the only thing I need
to check now for completeness is what to do about lock upgrade/downgrades
which Win32 allows under some *very* strange circumstances.
Jeremy.
