debb471267 The big character set handling changeover!
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.

c24e6b41ea Ensured all the system calls in msdfs.c go through the vfs layer.
Added vfs calls to symlink() and readlink() with appropriate configure
checks.

32397e5bc6 configure:
configure.in:
include/config.h.in:
include/profile.h:
smbd/vfs-wrap.c:
smbd/vfs.c:
Added fchmod and fchown to VFS (sorry Gerald - but we needed them anyway).
smbd/dosmode.c:
smbd/files.c:
printing/printfsp.c:
smbd/close.c:
smbd/open.c:
Fixed "dos filemode" correctly so there are no race conditions. Forces test
of open of file O_WRONLY before allowing fchmod as root. Afterwards, calls
standard close function that preserves POSIX locks due to POSIX-me-harder
braindamage. :-). Andrew please review this code.
Also - in removing the tmpdir param in smbrun an extra NULL parameter
was missed in each print_run_command() call (which is a varargs fn.).
Now fixed.

smbd/vfs-wrap.c:
smbd/vfs.c: Added fchmod_acl and chmod_acl.
lib/substitute.c:
smbd/lanman.c:
smbd/open.c:
smbd/process.c:
smbd/reply.c:
smbd/service.c: Removed sessetup_user variable. Added current_user_info struct
which conatins domain info etc. Added '%D' for client domain parameter.

d0fbb4f5d9 Added a VFS version return to init call. Allows smbd to fail an init if
versions don't match.

dfe77c7046 Herb's warning fixes. Also the POSIX locking fix.
We now use our own vfs layer to do get/set acl calls (hurrah!).

b07611f815 Restructuring of vfs layer to include a "this" pointer - can be an fsp or
a conn struct depending on the call.
We need this to have a clean NT ACL call interface.
This will break any existing VFS libraries (that's why this is pre-release
code).
Andrew gets credit for this one :-) :-).

In addition - added Herb's WITH_PROFILE changes - Herb - please examine
the changes I've made to the smbd/reply.c code you added. The original
code was very ugly and I have replaced it with a
START_PROFILE(x)/END_PROFILE(x) pair using the preprocessor.
Please check this compiles ok with the --with-profile switch.

b90af886a9 Vector get_nt_acl/set_nt_acl via vfs. POSIX ACL support should be added
above this layer.

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.

46092ee141 Moved uglyness needed in fcntl locking (64->32 bit mapping, NFS
errors etc.) into locking/posix.c, where it is needed. fcntl_lock in lib/util.c
is now very small and clean.
Added (*lock) op to vfs layer.

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.

Jeremy.

6c442d68af Change to vfs API. POSIX states fsync should return an int, not a void.

13a2cf80f6 Busting up of source/include/smb.h into smaller pieces which can be
#included by VFS modules without bringing in too much other junk.

38cc03ae0c Added service name to vfs_connection_struct.
Added a vfs_options struct for passing smb.conf parameters to VFS
modules.
