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.

673ab50c4c ldap back-end database development
Makefile:

	created PASSBD_OBJ group

includes.h:

	added #ifdef USE_LDAP to #include <ldap> headers

ldap.c:

	- renamed "_machine" to "_trust" everywhere.
	- added sam_passwd support routines
	- removed get_ldappwd_entry function: replaced with get_sampwd_entry
	- removed getldappwnam/uid: replaced with getsampwnam/uid
	- other messing about bits which are probably going to annoy the
	  hell out of jean-francois (sorry!)

mkproto.awk:

	- added stuff to wrap ldap.c protos with #ifdef USE_LDAP
	- added uid_t and gid_t return results to the prototype generation

passdb.c:

	- created getsam21pwent, add_sam21pwd_entry, mod_sam21pwd_entry.
	- modified getsampwnam/uid and created getsam21pwnam/rid functions
	  to replace the local get_smbpwd_entry() and get_ldappwd_entry()
	  functions, which jeremy didn't like anyway because they were
	  dual-purpose.
	- added utility routines which are or may be useful to all the
	  password database routines.

password.c:

	- renamed "machine_" to "trust_" everywhere.

smbpass.c:

	- removed get_smbpwd_entry function: replaced it with get_sampwd_entry
	  functions in passdb.c
	- moved code that decoded acct_ctrl into passdb.c
	- moved encode_acct_ctrl into passdb.c
	- removed getsmbpwnam/uid: replaced with getsampwnam/uid
	- renamed "machine_" to "trust_" everywhere.

smbpasswd.c:

	- renamed "machine_" to "trust_" everywhere.

util.c:

	- moved gethexpwd function into passdb.c

lib/rpc/server/srv_util.c:

	- moved user_rid_to_uid, group_rid_to_rid etc etc into passdb.c

ee09e9dadb changed to use slprintf() instead of sprintf() just about
everywhere. I've implemented slprintf() as a bounds checked sprintf()
using mprotect() and a non-writeable page.

This should prevent any sprintf based security holes.

29462c8d7a Updated OSF1_ENH_SEC mode password handling.
This now tries Enhanced passwords first and if this fails trys Basic
mode (ie: Unix /etc/passwd) authentication. This only happens when
OSF1_ENH_SEC is defined at compilation.
-
Luke Leighton
57b01ad4ff created "passdb.c" which is an interface point to (at present) either
smbpasswd or ldap passwd, at compile-time (-DUSE_LDAP).

_none_ of the functions in ldap.c or smbpass.c should be called directly:
only those in passdb.c should be used.

-DUSE_LDAP is unlikely to compile at the moment.

d28427f21f smbpass.c: Fixed machine_passwd_lock() problems.

b5187ad6a3 Fixes for the %U and %G problems people have reported.
Essentially, multiple session_setup_and_X's may be done
to an smbd. As there is only one global variable containing
the requested connection name (sessionsetup_user), then any
subsequent sessionsetups overwrite this name (causing %U
and %G to get the wrong name). This is particularly common
when an NT client does a null session setup to get a
browse list after the user has connected, but before
a share has been mounted.

These changes store the requested_name in the vuid structure
(so this only really works for user level and above security)
and copies this name back into the global variable before
the standard_sub call.

315e26c23a password.c:
added become_root / unbecome_root around the get machine account password.

smbpass.c:

	cleaning up code.

	- turning if (BOOL_expr == False) into if (BOOL_expr)
	  what if you test if (BOOL_expr == True) and someone defines
	  True to be -1 on one system and 1 on another?  or if you get
	  inconsistent return results between developers

	- removed if ((FILE*) == 0) and made this if ((FILE*) == NULL) -
	  cannot assume that NULL is zero integer.  plus there are typecast
	  issues to deal with

	- removed return (ret == 0) ? True : False and made this return ret == 0
	  rely on the compiler to return correct BOOL value: not all developers
	  will return True or False #defines: stick with BOOL test (non-zero).

	- removed if (ret == False) replaced with if (!ret)

	- bug where instead of if (sizeof(pstring)-len-len-6 < 0) it had a
	  boolean test if (pstring-len-len-6).

	- removed "." after debugging of filenames: the "." - a fullstop -
	  looked like it was part of the filename, making things difficult
	  to sort out.

still to be resolved: the global_myname isn't set up, such that the
machine account password file is named "TEST3..mac".

17b94a7084 This is the checkin that adds the security=domain functionality.
WARNING - so far this has only been tested against a Samba PDC
(still waiting for IS to add me the machine accounts :-).

Still missing is the code in smbpasswd that will add a machine
account password and change it on the domain controller, but
this is not hard, and I will check it in soon.

866406bfe3 This looks like a big change but really isn't.
It is changing the global variables "myname" and "myworkgroup"
to "global_myname" and "global_myworkgroup" respectively.

This is to make it very explicit when we are messing
with a global (don't ask - it makes the domain client
code much clearer :-).

1161cfb7f2 Modified interfaces to getting smb password entries from
get_smbpwd_entry (now an internal function to smbpass.c)
to a more UNIX-like :

getsmbpwnam() - get entry by name.
getsmbpwuid() - get entry by uid.

Changed the type returned by the smbpasswd enumeration
functions to be a void * so that people don't come to
depend on it being a FILE *.

These abstractions should make it much easier to
replace the smbpasswd file with a better backend
in future.

Other files changed are to match the above changes.

a776058900 this isn't a big commit, it just looks like it :-)
I needed the client_name() and client_addr() functions in swat so I
could tell who was connecting from where. The problem was that these
functions didn't take a file descriptor parameter they just used
the global "Client".

So I needed to change all calls to pass a parameter ... lots of files.

118ba4d77a "For I have laboured mightily on Luke's code, and hath broken
all I saw" - the book of Jeremy, chapter 1 :-).

So here is the mega-merge of the NTDOM branch server code.
It doesn't include the new client side pieces, we'll look
at that later.

This should give the same functionality, server wise, as
the NTDOM branch does, only merged into the main branch.

Any fixes to domain controler functionality should be
added to the main branch, not the NTDOM branch.

This code compiles without warnings on gcc2.8, but will
need further testing before we are sure all the working
functionality of the NTDOM server branch has been
correctly carried over.

I hereby declare the server side of the NTDOM branch
dead (and all who sail in her :-).

f27966957f attempting to mark up 32 bit error codes, needed for NT domains.
separated out smb server-mode password validation into a separate file.
added called and calling netbios names to client gen state: referenced
section in rfc1002.txt.
created workstation trust account checking code in ntclient.c

there might be a bug in reply_session_setup_andX.  i indented and added { }
around single-line if statements: the lm password checking code now doesn't
look right (around the GUEST_SESSSETUP bits).  *no code semantics have been
changed by the indentation process*.

1bd084b3e6 following a cvs error, i am rewriting this monster-commit. with bad grace.
Modified Files:
---------------

Makefile:

	adding extra files

ipc.c :

	send_trans_reply() - alignment issue.  this makes the alignment
	the same as that in NT.  this should be looked at by people who
	understand the SMB stuff better than i.

	api_fd_commands[] - added samr and wkssvc pipes.

loadparm.c :

	lp_domain_controller() changed to mean "samba is a domain controller".
	it's a "yes/no" parameter, now.  no, it isn't used _anywhere_.

namedbwork.c nameelect.c :

	if "domain controller = yes" then add SV_TYPE_DOMAIN_CTRL to the
	host _and_ workgroup announcements.  yes, you must do both: nt does.

namelogon.c :

	important NETLOGON bug in SAMLOGON request parsing, which may be
	the source of some people's problems with logging on to the Samba PDC.

password.c :

	get_smbpwnam() renamed to get_smbpwd_entry().

pipes.c :

	added samr and wkssvc pipes.

proto.h :

	usual.  can we actually _remove_ proto.h from the cvs tree, and
	have it as one of the Makefile dependencies, or something?

reply.c :

	get_smbpwnam() renamed to get_smbpwd_entry() - also changed response
	error code when logging in from a WORKSTATION$ account.  yes, paul
	is right: we need to know when to return the right error code, and why.

server.c :

	added call to reset_chain_pnum().

	#ifdef NTDOMAIN added call to init_lsa_policy_hnd() #endif.  jeremy,
	you'd be proud: i did a compile without NTDOMAIN, and caught a link
	error for this function.

smb.h :

	defines and structures for samr and wkssvc pipes.

smbpass.c :

	modified get_smbpwnam() to get_smbpwd_entry() and it now takes
	two arguments.  one for the name; if this is null, it looks up
	by smb_userid instead.

	oh, by the way, smb_userids are actually domain relative ids
	(RIDs).  concatenate a RID with the domain SID, and you have
	an internet globally unique way of identifying a user.

	we're using RIDs in the wrong way....

	added mod_smbpwnam() function.  this was based on code in smbpasswd.c

rpc_pipes/lsaparse.c :

	added enum trusted domain parsing.  this is incomplete: i need
	a packet trace to write it properly.

rpc_pipes/pipe_hnd.c :

	added reset_chain_pnum() function.

rpc_pipes/pipenetlog.c :

	get_smbpwnam() function renamed to get_smbpwd_entry().

	arcfour() issues.

	removed capability of get_md4pw() function to automatically add
	workstation accounts.  this should either be done using
	smbpasswd -add MACHINE$, or by using \PIPE\samr.

rpc_pipes/pipe_util.c :

	create_pol_hnd() - creates a unique LSA Policy Handle.  overkill
	function: uses a 64 bit sequence number; current unix time and
	the smbd pid.

rpc_pipes/smbparse.c :

	arcfour() issues.

	smb_io_unistr2() should advance by uni_str_len not uni_max_len.

	smb_io_smb_hdr_rb() - request bind uses uint16 for the context
	id, and uint8 for the num_syntaxes.  oops, i put these both as
	uint32s.


Added Files:
------------

rpc_pipes/lsa_hnd.c :

	on the samr pipe, allocate and associate an LSA Policy Handle
	with a SID.  you receive queries with the LSA Policy Handle,
	and have to turn this back into a SID in order to answer the
	query...

rpc_pipes/pipesamr.c rpc_pipes/samrparse.c

	\PIPE\samr processing.  samr i presume is the SAM Replication pipe.

rpc_pipes/pipewkssvc.c rpc_pipes/wksparse.c

	\PIPE\wkssvc processing.  the Workstation Service pipe?


holy cow.

11de90f972 rewrote the password server code using the new clientgen.c client
interface

The new code uses a source netbios name equal to the Samba servers
name, not the client name. It also uses NetWkstaUserLogon to do a full
network logon. This means it will honour the servers logon
restrictions (such as login times etc).
-
Luke Leighton
c6c28a4c3c util.c password.c :
added automount_server() function which, if -DAUTOMOUNT is in use,
	returns the server name of the NIS auto.map entry.  otherwise,
	it returns local_server.

	added use of automount_server() for a new substitution %N for NIS
	home server.  this defaults, via automount_server(), to the same
	functionality as %L if -DAUTOMOUNT is not used.

	removed vuser->home_share.  moved code that grabbed the servername
	into the separate function automount_server().

loadparm.c :

	created "logon drive" (default of "")
	created "logon home"  (default of "\\%N\%U")
	changed default of "logon path" from NULL to "\\%N\%U\profile".

ipc.c pipenetlog.c :

	use lp_logon_drive(), lp_logon_home() and lp_logon_path() in their
	now easier-to-use form (don't have to check if *lp_logon_path() and
	manually substitute a default of \\%L\%U and do a standard_sub_basic()
	on the result, because the default automatically does this.
