f96625ec12 Restructuring of the code to remove dos_ChDir/dos_GetWd and re-vector them
through the VFS. All file access/directory access code in smbd should now
go via the vfs. Added vfs_chown/vfs_chmod calls. Still looking at vfs_get_nt_acl()
vfs_set_nt_acl() call API design.

e28d01b744 Added an NT_USER_TOKEN structure that is copied/passed around associated
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.

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...

dcf3249bb9 Fix for mounting a printer as a share. Not that there's anything
specifically wrong with this, but Samba is fooled by the client into
thinking the printer is a file share.  Files copied to the share gather
dust in the spool directory and aren't printed.

This patch has the effect of not allowing printers to be mounted as file
shares.  Not sure whether this is the correct solution or not.
{Jeremy,JF,Tridge} please check!

974813f0d4 added spool_io_printer_driver_info_level_6()
thsi function and the associated header structure were autogenerated
using a little awk based code geerator I wroe ths evening. I'll commit
that next ...

ada483cb56 - changed smb_getpwnam() to use winbind style usernames
- finished ntdom -> winbind rename in head

92109d7b3c more merging voodoo
this adds "#define OLD_NTDOMAIN 1" in lots of places. Don't panic -
this isn't permanent, it should go after another few merge steps have
been done

8b7a10febe a minimal change to get appliance mode to work with winbindd
we needed to accept usernames of the form DOMAIN/user, which means we
needed to pass the domain to a getpwnam() like routine in certain
critical spots.

What I'd rather do is get rid of "char *user" everywhere and use the
new userdom_struct, but that will have to wait a few days.

148628b616 Added sys_fork() and sys_getpid() functions to stop the overhead
of doing a system call every time we want to just get our pid.

858eb53dc5 Moved deletion of vfs handle into smbd/conn.c as it was being done too
soon in smbd/service.c (file operations were being done after the
handle was closed).

It looks cleaner in smbd/conn.c as it is part of the closing of a conn
struct anyway.

5937ab14d2 finally got sick of the "extern int Client" code and the stupid
assumption that we have one socket everywhere

while doing so I discovered a few bugs!

1) the clientgen session retarget code if used from smbd or nmbd would
cause a crash as it called close_sockets() which closed our main
socket! fixed by removing close_sockets() completely - it is unnecessary

2) the caching in client_addr() and client_name() was bogus - it could
easily get fooled and give the wrong result. fixed.

3) the retarget could could recurse, allowing an easy denial of
service attack on nmbd. fixed.

3aad500c0f Mega-VFS merge. Yeah baby!
Synopsis: change every disk access function to work through a vfs_ops
structure contained in the connection_struct.

Andrew Tridgell
4951755413 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!

054195df9b 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.

36d7cb4ccc Moved code that changes the pw_passwd entry (i.e shadow password and
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.

346c78d707 Changed the way a VFS is initialised. The vfs_init() function is
executed from the VFS object file and it returns a pointer to a
vfs_ops structure.  If any of the function pointers in vfs_ops are
NULL, then they are replaced with the standard disk functions.  This
should allow disk-related VFS modules to be easily added.  I've
written an auditing VFS module which logs various calls (connect,
disconnect, mkdir, rmdir, open and a few others) to syslog in a couple
of pages of code.

Thanks to tridge for various useful suggestions.

Tim Potter
15805164fe Call VFS initialisation, share connect and share disconnect functions.
Initialise VFS function pointers with symbols from the 'vfs object'
file, use disk pointers otherwise.

Added a hook to check for a 'default' VFS share (like the [homes]
section).  Currently empty - I'm unsure whether this will be useful or
not.

0d21e1e609 - 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.

e570db46fc Got very strict about the differences and uses of
uid_t, gid_t and vuid. Added sys_getgroups() to get
around the int * return problem. Set correct datatypes
for all uid, gid and vuid variables.

a6d194886a this completes the splitup of server.c.
the splitup was done with an axe, not a scalpel, so there are some
rough edges. I mostly wanted to get the general form right with fine
tuning of what goes where to come later. Still, this is better than
what we had before where server.c was a general repository for
anything that didn't fit elsewhere.
