This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.
the pam password change code to ensure that existing and working password
chat scripts don't break with 2.2.1. PAM password changing has to be explicitly
requested.
Allowed wildcards in pam password change matching (matches password chat
script matching). Had to add const (sorry Tim :-) to ms_fnmatch() to
stop warnings. Don't worry - the const changes are isolated and don't
cause any other warnings :-).
Jeremy.
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.

call to ms_fnmatch(). This also removes all the Win9X semantics stuff
and a bunch of other associated cruft.
- moved the stat cache code into statcache.c
- fixed the uint16 alignment requirements of ascii_to_unistr() and
unistr_to_ascii()
- trans2 SMB_FIND_FILE_BOTH_DIRECTORY_INFO returns the short name as
unicode always (at least thats what NT4 does)
- fixed some errors in the in-memory tdb code. Still ugly, but doesn't
crash as much
is to pass DOMAIN_NAME$ and SEC_CHAN_DOMAIN instead of WKSTA_NAME$ and
SEC_CHAN_WKSTA.
modified check_domain_security to determine if domain name is own domain,
and to use wksta trust account if so, otherwise check "trusting domains"
parameter and use inter-domain trust account if so, otherwise return
False.
weird unixware stuff) into _Get_Pwnam() to fix a memory allocation bug.
Note that the Get_Pwnam() function now returns a const struct passwd *
as a hint to other developers not to change entries in the struct
passwd.
connection_struct in a call to OpenDir.
JF, you fixed a similar bug in printing/nt_printing.c, I think your fix
is incorrect as global configuration files should not go through a VFS.
----------------------------
- removed DOM_RID4
- removed SAMR_UNKNOWN_32
- added SAMR_SET_USERINFO (opcode 0x32)
- added level 0x1 to SAMR_QUERY_DOM_INFO (needed for create user)
- fixed pwdb_gethexpwd() it was failing on XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
- added mod_sam21pwd_entry()
- preparing to call mod_sam21pwd_entry()
- added "user session key" to user_struct.dc. this is md4(nt#) and is
needed to decode user's clear-text passwords in SAMR_SET_USERINFO.
- split code out in chgpasswd.c to decode 516 byte password buffers.
No more ugly static library buffers and all functions take a destination
string length (especially unistrcpy was rather dangerous; we were only
saved by the fact that datagrams are limited in size).
- split sam_passwd and smb_passwd into separate higher-order function tables
- renamed struct smb_passwd's "smb_user" to "unix_user". added "nt_user"
plus user_rid, and added a "wrap" function in both sam_passwd and smb_passwd
password databases to fill in the blank entries that are not obtained
from whatever password database API instance is being used.
NOTE: whenever a struct smb_passwd or struct sam_passwd is used, it MUST
be initialised with pwdb_sam_init() or pwd_smb_init(), see chgpasswd.c
for the only example outside of the password database APIs i could find.
- added query_useraliases code to rpcclient.
- dealt with some nasty interdependencies involving non-smbd programs
and the password database API. this is still not satisfactorily
resolved completelely, but it's the best i can do for now.
- #ifdef'd out some password database options so that people don't
mistakenly set them unless they recompile to _use_ those options.
lots of debugging done, it's still not finished. the unix/NT uid/gid
and user-rid/group-rid issues are better, but not perfect. the "BUILTIN"
domain is still missing: users cannot be added to "BUILTIN" groups yet,
as we only have an "alias" db API and a "group" db API but not "builtin-alias"
db API...
Tidied up some of the mess (no other word for it). Still doesn't
compile cleanly. There are calls with incorrect parameters that
don't seem to be doing the right thing.
This code still needs surgery :-(.
Jeremy.
smbd/chgpasswd.c: Fixed (my) stupid bug where I was returning stack based variables. Doh !
smbd/trans2.c: Allows SETFILEINFO as well as QFILEINFO on directory handles.
Jeremy.
- removed debug info in struni2 and unistr2 (security risk)
- rpc_pipe function was getting pointer to data then calling realloc *dur*
- password check function, the start of "credential checking",
user, wks, domain, pass as the credentials (not just user,pass which
is incorrect in a domain context)
- cli_write needs to return ssize_t not size_t, because total can be -1
if the write fails.
- fixed signed / unsigned warnings (how come i don't get those any more
when i compile with gcc???)
- nt password change added in smbd. yes, jeremy, i verified that the
SMBtrans2 version still works.

prompted by the interpret_security() dead code that Jean-Francois
pointed out I added a make target "finddead" that finds potentially
dead (ie. unused) code. It spat out 304 function names ...
I went through these are deleted many of them, making others static
(finddead also reports functions that are used only in the local
file).
in doing this I have almost certainly deleted some useful code. I may
have even prevented compilation with some compile options. I
apologise. I decided it was better to get rid of this code now and add
back the one or two functions that are needed than to keep all this
baggage.
So, if I have done a bit too much "destroying" then let me know. Keep
the swearing to a minimum :)
One bit I didn't do is the ubibt code. Chris, can you look at that?
Heaps of unused functions there. Can they be made static?
the head of an SMB request (ie. are part of a chain) will not be queued -
this will be fixed when we move to the new chain code. In practice, this
doesn't seem to cause much of a problem (in my admittedly limited testing)
bug a debug level zero message will be placed in the log when this
happens to help determine how real the problem is.

lock queue processing into idle loop.
smbd/reply.c: Added queue pushes for SMBlock, SMBlockread and SMBlockingX.
Jeremy.
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.
local.h: Kept FSTYPE_STRING as Samba for now.
nmbd_browsesync.c: Added bugfix from Matt Chapman mattyc@cyberdude.com
- lmb_browserlist is now a struct ubi_dlList not a
struct browse_cache_record *.
server.c:
smb.h:
uid.c:
password.c: Removed attrs code - it is not used anywhere.
