69d24d869b first cut at using the tdb code for the connections structure, the
SWAT status page and smbstatus. It made the code _much_ simpler, I
wish we'd done a database module a long time ago!

f6276724ba changed function name of get_home_dir() to get_unixhome_dir(), to stop
clash with gnu readline library.

fixed issue with [homes] service not being there - call lp_add_home()
just before starting the msrpc processing.

4f8a24522c final part of "first" phase converting over to msrpc daemon architecture.
done a minimal amout of clean-up in the Makefile, removing unnecessary
modules from the link stage.  this is not complete, yet, and will
involve some changes, for example to smbd, to remove dependencies on
the password database API that shouldn't be there.  for example,
smbd should not ever call getsmbpwXXX() it should call the Samr or Lsa
API.

this first implementation has minor problems with not reinstantiating
the same services as the caller.  the "homes" service is a good example.

a0ba234cf9 the first independent msrpc daemon - lsarpcd.
one horrible cut / paste job from smbd, plus a code split of shared
components between the two.

the job is not _yet_ complete, as i need to be able to do a become_user()
call for security reasons.  i picked lsarpcd first because you don't
_need_ security on it (microsoft botched so badly on this one, it's not
real.  at least they fixed this in nt5 with restrictanonymous=0x2).
fixing this involves sending the current smb and unix credentials down
the unix pipe so that the daemon it eventually goes to can pick them
up at the other end.

i can't believe this all worked!!!

24a069eac3 modified domain_client_validate to take trust account name / type. this
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.

b231d2fafa - added DCE/RPC "fault" PDU support.
- disabled (AGAIN) the GETDC "if (MAILSLOT\NTLOGON)" code that will get
NT5rc2 to work but WILL break win95 (AGAIN).  this needs _not_ to be
re-enabled but to be replaced with a better mechanism.

- added SMBwrite support (note: SMBwriteX already existed) as NT5rc2 is
sending DCE/RPC over SMBwrite not SMBwriteX.

939f6d6794 more dfs stuff. this looks like it's going to be more appropriate to use
the vfs tables.  at the moment, i replaced all calls to unix_convert()
with unix_dfs_convert().

ac61e4aee2 lengths of NT passwords when "encrypt passwords = no" can be completely
random.  values seen can be as high as 18255.  this fails the check
of <= 24 which sets NT password length to 0, effectively ignoring it.
the <= 24 was removed in reply_sesssetup_X.

43a460075a SAM database "set user info".
----------------------------

- 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.

c6ad04b8fb attempting to fix "domain user map" up, but it's a bit complicated.
i may simply go for a response in the NetSamLogon returning the
unix username, forcing the NT user to appear to be a unix user,
however even that is fraught with implications.

might just have to go the whole hog and do this tuple thing,
"unix_name + nt_name" always associated together...


issue with api_net_sam_logon, getsam21pwent() being called twice,
the second time overwriting static buffer data (argh) so had to
make a copy.

noticed a nested "become_root()"/"unbecome_root()" which will have
to be tracked down...

74d539f557 - group database API. oops and oh dear, the threat has been carried out:
the pre-alpha "domain group" etc parameters have disappeared.

- interactive debug detection

- re-added mem_man (andrew's memory management, detects memory corruption)

- american spellings of "initialise" replaced with english spelling of
  "initialise".

- started on "lookup_name()" and "lookup_sid()" functions.  proper ones.

- moved lots of functions around.  created some modules of commonly used
  code.  e.g the password file locking code, which is used in groupfile.c
  and aliasfile.c and smbpass.c

- moved RID_TYPE_MASK up another bit.  this is really unfortunate, but
  there is no other "fast" way to identify users from groups from aliases.
  i do not believe that this code saves us anything (the multipliers)
  and puts us at a disadvantage (reduces the useable rid space).
  the designers of NT aren't silly: if they can get away with a user-
  interface-speed LsaLookupNames / LsaLookupSids, then so can we.  i
  spoke with isaac at the cifs conference, the only time for example that
  they do a security context check is on file create.  certainly not on
  individual file reads / writes, which would drastically hit their
  performance and ours, too.

- renamed myworkgroup to global_sam_name, amongst other things, when used
  in the rpc code.  there is also a global_member_name, as we are always
  responsible for a SAM database, the scope of which is limited by the role
  of the machine (e.g if a member of a workgroup, your SAM is for _local_
  logins only, and its name is the name of your server.  you even still
  have a SID.  see LsaQueryInfoPolicy, levels 3 and 5).

- updated functionality of groupname.c to be able to cope with names
  like DOMAIN\group and SERVER\alias.  used this code to be able to
  do aliases as well as groups.  this code may actually be better
  off being used in username mapping, too.

- created a connect to serverlist function in clientgen.c and used it
  in password.c

- initialisation in server.c depends on the role of the server.  well,
  it does now.

- rpctorture.  smbtorture.  EXERCISE EXTREME CAUTION.

9bb7ac81b6 Reasonably large change to give us *exactly* correct NT delete on close semantics.
This was trickier than it looks :-). Check out the new DELETE_ON_CLOSE
flag in the share modes and the new code that iterates through all open
files on the same device and inode in files.c and trans2.c

Also changed the code that modifies share mode entries to take
generic function pointers rather than doing a specific thing so
this sort of change should be easier in the future.

01de603084 - dce/rpc code
- 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.

3b7cee95ac look at the CAP_NT_SMBS bit in the client capabilities to determine if
we should serve up volume labels as ascii or unicode.

NT wants ascii, W95 wants unicode. It's a crazy protocol!

5e634ef68c 3 changes:
1) use lp_fstype() instead of FSTYPE_STRING
2) added SMB_SEARCH_BITS to the TconX reply options (in vwv3). I noted
   that NT sets this (undocumented) bit and setting it helped get
   autorun from exported cdroms working.
3) fixed volume labels in QFSINFO level 258.

I made these changes while getting the Encyclopadia Brittanica CD to
run from a Samba drive. (I bought it for Sue yesterday). The first
and second changes allowed Samba to export CDs with autorun info and
the client will autorun it when mounted. There are all sorts of nasty
implications in that that perhaps we can go into on
samba-technical. Think about creating some autorun info in /tmp/ then
waiting for people to mount it as scratch space ...

The last change was because EB wanted the right volume label. The code
we had used a non unicode volume label but tests with W95->NT4 showed
that it has to be unicode. There was a note in the code from Jeremy
saying that he thought it should _not_ be unicode. Jeremy, can you
explain why? It certainly didn't work as non-unicode (the client
displays a garbage volume label) and when I fixed it to use unicode it
all worked from Win95.

and in case anyone is interested EB98 now works fine from a Samba
drive :)
