92a777d0ea BIG patch...
This patch makes Samba compile cleanly with -Wwrite-strings.
 - That is, all string literals are marked as 'const'.  These strings are
always read only, this just marks them as such for passing to other functions.

What is most supprising is that I didn't need to change more than a few lines of code (all
in 'net', which got a small cleanup of net.h and extern variables).  The rest
is just adding a lot of 'const'.

As far as I can tell, I have not added any new warnings - apart from making all
of tdbutil.c's function const (so they warn for adding that const string to
struct).

31d7168530 Add LSA RPC 0x2E, lsa_query_info2. Only level implemented is 0x0c, which
is netbios and dns domain info.  Also add code to set/fetch the domain GUID
from secrets.tdb (although set is not yet called by anyone).

0bdd94cb99 Partly based on the work by mimir (Rafal Szczesniak
<mimir@diament.ists.pwr.wroc.pl>) this patch allows samba to correctly
enumerate its trusted domains - by exaimining the keys in the secrets.tdb file.

This patch has been tested with both NT4 and rpcclient/wbinfo, and adds
some extra functionality to talloc and rpc_parse to allow it to deal with
already unicode strings.

Finally, this cleans up some const warnings that were in net_rpc.c by pushing
another dash of const into the rpc client code.

84289a9bf4 add lsa_query_secobj server code. level 4 is the ACL, level 1 is the
owner. that's basic stuff.

got the POLICY_ define from TNG but they are also in an include file in
the NT SDK.

3f0a9ef2b8 Changed again how the privilege list is handled in the group mapping code.
This time it's a PRIVILEGE_SET struct instead of a simple uint32 array. It
makes much more sense. Also added a uint32 systemaccount to the GROUP_MAP
struct as some privilege showing in USRMGR.EXE are not real privs but a
bitmask flag. I guess it's an heritage from NT 3.0 ! I could setup an NT
3.1 box to verify, but I'm too lazy (yes I still have my CDs).

Added 3 more LSA calls: SetSystemAccount, AddPrivileges and
RemovePrivileges, we can manage all this privilege from UserManager.

Time to change the NT_USER_TOKEN struct and add checks in all the rpc
functions. Fun, fun, fun.

59229b9025 Changes from APPLIANCE_HEAD:
source/rpc_parse/parse_lsa.c
        - off by one unistr length bug in init_lsa_trans_name()

    source/lib/util_sid.c
        - resolve more BUILTIN sid values to names.

    source/nsswitch/wb_client.c
        - fix typo in debug message
        - set errno on error so we don't get bogus value from last failure.

    source/rpc_server/srv_spoolss_nt.c
        - add debug to track number of open printer handles for ease of
          tracking handle leaks in the future.

    source/rpc_server/srv_lsa.c
        - fix off-by-one string bug.  This was preventing NT from
          displaying names for well-know SIDs in printer permissions
          dialog.

ce4f461965 Never free anything in the rpc_parse/prs_XXX functions. Do it in the enclosing
function.
lib/util_unistr.c: Check lengths *before* reading source - prevent uninitialised
memory reads.
Jeremy.

Jean-François Micouleau
69fe739303 lib/util_unistr.c:
rewrote unistr2_to_ascii() to correct a bug seen on SGI boxes.

rpc_parse/parse_misc.c:
rpc_parse/parse_prs.c:
        rewrote of BUFFER5 handling to NOT byteswap when it was already in
        network byte order.

rpc_parse/parse_samr.c:
        cleanup of samr_io_q_lookup_domain(), remove the over-parsing by 2
        bytes.

rpc_server/srv_lsa.c:
        UNISTR2 strings need to be NULL terminated to pleased W2K.

rpc_server/srv_spoolss_nt.c:
        use snprintf instead of safe_strcpy as we want the string
        truncated at 32 chars.


That should fix SUN and SGI box not able to act as printserver and the
problem with joining from a W2K wks.

d8bf81553c last part of W2K support.
the trust domain list reply on netlogon pipe was wrong, interim hack until
we have full trust relationships.

changed some unistr2 to parse the ending NULL char.

added a prs_align_needed() function. much like a prs_align but with a
condition. needed for the unistr2 parsing.

74af3e2cae Changes from APPLIANCE_HEAD (per Tim Potter):
- make proto
	- addition of function to convert from errno values to NT status codes
	  (source/lib/error.c)
	- purge queue done without full access permission will purge only the
	  jobs owned by that user, rather than failing.
	- unlock job database tdb before sending job to printer
	- in print_job_start(), ensure that we don't pick a jobid with an existing
	  temporary file that may be owned by another user, as it causes silent
	  failures.
	- fixes for printer permission checking for NT5 clients
	  (source/include/rpc_spoolss.h, source/printing/nt_printing.c,
	   source/printing/printing.c, source/rpc_server/srv_spoolss_nt.c)
	- change from uint8 to 'enum SID_NAME_USE' (source/rpc_server/srv_lsa.c)
	- fixed memory leaks for win95 driver download process
	  (source/smbd/lanman.c)
	- properly free prs_structs and dacl in testsuite/printing/psec.c

5e5cc6efe2 Started to canonicalize our handling of uid -> sid code in order to
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...

rpc_parse/parse_spoolss.c: Added note about prs_align when marshalling a SEC_DESC...
rpc_server/srv_lsa.c: Tim - your changes broke the display of the 'everyone' group

96addba216 Simplified server pipe implementation by changing arguments passed down

ab0ecc39d6 This is a *big* checkin that may break some things, but implements the
new open mechanism Andrew & I discussed.

config.sub:
configure: Included the QNX patch.

include/vfs.h:
smbd/vfs-wrap.c:
smbd/vfs.c: Added ftruncate vfs call (needed).

Note that we will also need locking calls in the vfs (to be added).

lib/util_unistr.c:
nmbd/nmbd_processlogon.c: Fix for NT domain logons causing nmbd to core dump.
                          Also fix for sidsize DOS bug.

locking/locking.c: Check value of ret before using it for memdup.

printing/printing.c: Convert print_fsp_open to return an allocated fsp.

rpc_server/srv_lsa.c: Fix for NT domain logons.

I have removed all use of lp_share_modes() from the code (although I
left the parameter in the table for backwards compatibility). It no longer makes
sense for this to exist.

smbd/close.c: Removed lp_share_modes().
smbd/fileio.c: Fixed parameters to unlock_share_entry call in panic code.
smbd/files.c: Correctly set the unix_ERR_code to ERRnofids on fsp allocation fail.

smbd/nttrans.c:
smbd/reply.c:
smbd/trans2.c: Changed all occurrences of open_file_shared/open_directory/
               open_file_stat to return an fsp from the call.

smbd/open.c: Changed all occurrences of open_file_shared/open_directory/
             open_file_stat to return an fsp from the call.

In addition I have fixed a long standing race condition in the deny mode
processing w.r.t. two smbd's creating a file. Andrew, please note that
your original idea of using open with O_EXCL in this case would not work
(I went over the races very carefully) and so we must re-check deny modes
*after* the open() call returns. This is because there is a race between
the open with O_EXCL and the lock of the share mode entry. Imagine the
case where the first smbd does the open with O_EXCL and a deny mode of DENY_ALL,
but is pre-empted before it locks the share modes and creates the deny
mode entry for DENY_ALL. A second smbd could then come in with O_RDONLY
and a deny mode of DENY_NONE and the two opens would be allowed.

The *only* way to fix this race is to lock the share modes after the
open and then do the deny mode checks *after* this lock in the case
where the file did not originally exist.

This code will need extensive testing but seems to initially work.

cfaea90529 added the following message to all dce/rpc client/server code, except
the spoolss code (it's cut from TNG) and the smb-dce/rpc interface
code that jeremy has been working up to TNG-functionality.

i also want this message to go into SAMBA_2_0 and SAMBA_2_0_RELEASE,
because it is intolerable that potentially good modifications be made
to code that is going to be thrown away, and people waste their time
fixing bugs and adding enhancements that have already been carried
out already, up to two years ago in the TNG branch.

/*
 * THIS CODE IS OUT-OF-DATE BY TWO YEARS, IS LEGACY DESIGN AND VERY, VERY,
 * INCOMPLETE.  PLEASE DO NOT MAKE ANY FURTHER ENHANCEMENTS TO THIS CODE
 * UNLESS THEY ARE ALSO CARRIED OUT IN THE SAMBA_TNG BRANCH.
 *
 * PLEASE DO NOT TREAT THIS CODE AS AUTHORITATIVE IN *ANY* WAY.
 *
 * REPEAT, PLEASE DO NOT MAKE ANY MODIFICATIONS TO THIS CODE WITHOUT
 * FIRST CHECKING THE EQUIVALENT MODULE IN SAMBA_TNG, UPDATING THAT
 * FIRST, *THEN* CONSIDER MAKING THE SAME MODIFICATION IN THIS BRANCH
 *
 * YOU WILL, ALMOST GUARANTEED, FIND THAT THE BUG-FIX OR ENHANCEMENT THAT
 * YOU THINK IS NECESSARY, HAS ALREADY BEEN IMPLEMENTED IN SAMBA_TNG.
 * IF IT HAS NOT, YOUR BUG-FIX OR ENHANCEMENT *MUST* GO INTO SAMBA_TNG
 * AS THE SAMBA_TNG CODE WILL REPLACE THIS MODULE WITHOUT REFERENCE TO
 * ANYTHING IN IT, WITH THE POSSIBLE RISK THAT THE BUG-FIX OR ENHANCEMENT

aa3c659a8d delineation between smb and msrpc more marked. smbd now constructs
pdus, and then feeds them over either a "local" function call or a "remote"
function call to an msrpc service.  the "remote" msrpc daemon, on the
other side of a unix socket, then calls the same "local" function that
smbd would, if the msrpc service were being run from inside smbd.

this allows a transition from local msrpc services (inside the same smbd
process) to remote (over a unix socket).

removed reference to pipes_struct in msrpc services.  all msrpc processing
functions take rpcsrv_struct which is a structure containing state info
for the msrpc functions to decode and create pdus.

created become_vuser() which does everything not related to connection_struct
that become_user() does.

removed, as best i could, connection_struct dependencies from the nt spoolss
printing code.

todo: remove dcinfo from rpcsrv_struct because this stores NETLOGON-specific
info on a per-connection basis, and if the connection dies then so does
the info, and that's a fairly serious problem.

had to put pretty much everything that is in user_struct into parse_creds.c
to feed unix user info over to the msrpc daemons.  why?  because it's
expensive to do unix password/group database lookups, and it's definitely
expensive to do nt user profile lookups, not to mention pretty difficult
and if you did either of these it would introduce a complication /
unnecessary interdependency.  so, send uid/gid/num_groups/gid_t* +
SID+num_rids+domain_group_rids* + unix username + nt username + nt domain
+ user session key etc.  this is the MINIMUM info identified so far that's
actually implemented.  missing bits include the called and calling
netbios names etc.  (basically, anything that can be loaded into
standard_sub() and standard_sub_basic()...)
