352a02bf5c Extra debug to see what errno is on write fail.

0b052f103e Added "strict allocate" per share parameter. This causes actual on-disk allocation
to be done. Without it just does the ftruncate.

c41fc06376 strchr and strrchr are macros when compiling with optimisation in gcc, so we can't redefine them. damn. -

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.

213cd0b519 Ok - fixed a bug in our levelII oplock code. We need to break a level II on
a byte range lock (write lock only, but Win2k breaks on read lock also so I
do the same) - if you think about why, this is obvious. Also fixed our client
code to do level II oplocks, if requested, and fixed the code where we would
assume the client wanted level II if it advertised itself as being level II
capable - it may not want that.

versions don't match.

66a5c05ec4 Ok - this is a big patch - and it may break smbd a bit (although
I hope not). If you encounter strange file-serving behavior after this
patch then back it out. I analysed our stat() usage and realised we
were doing approx. 3 stat calls per open, and 2 per getattr/setattr.
This patch should fix all that. It causes the stat struct returned
from unix_convert() (which now *must* be passed a valid SMB_STRUCT_STAT
pointer) to be passed through into the open code. This should prevent
the multiple stats that were being done so as not to violate layer
encapsulation in the API's.

Herb - if you could run a NetBench test with this code and do a
padc/par syscall test and also run with the current 2.2.0 code
and test the padc/par syscalls I'd appreciate it - you should
find the number of stat calls reduced - not sure by how much.

The patch depends on unix_convert() actually finding the file
and returning a stat struct, or returning a zero'd out stat
struct if the file didn't exist. I believe we can guarentee this
to be the case - I just wasn't confident enough to make this
an assertion before.

Ok ok - I did write this whilst at the Miami conference.....
sometimes you get a little free time at these things :-).

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.

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.

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.

d1827a3648 the bulk of the changes to get rid of fd_ptr and move print open
handling to printing/printing.c

most of this was just replacing things like fsp->fd_ptr->fd with fsp->fd

the changes in open.c are quite dramatic. Most of it is removing all
the functions that handled the fd multiplexing

ddde0ab9a1 Wrote VFS initialisation routines.
Converted some useful routines from doscalls.c and changed them to use
VFS I/O functions:

	dos_file_exist
	dos_read_data
	dos_write_data
	dos_transfer_file
	dos_readdirname

Some of these functions have been #ifdef'ed out of doscalls.c as they
are not used anywhere else.  Not sure whether they should be deleted
or not.  The remaining dos_* calls seem to be used by clients and for
locking stuff.  This should be cleaned up sometime.
