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.

------------
The following series of commits are for the new tdb based printing
backend. This completely replaces our old printing backend.
Major changes include:
- all print ops are now done in printing/*.c rather than scattered all
over the place
- system job ids are decoupled from SMB job ids
- the lpq parsers don't need to be nearly so smart, they only need to
parse the filename, the status and system job id
- we can store lots more info about a job, including the full job name
- the queue cache control is much better
I also added a new utility routine file_lines_load() that loads a text
file and parses it into lines. This is used in out lpq parsing and I
also want to use it to replace all of our fgets() based code in other
places.

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

Synopsis: change every disk access function to work through a vfs_ops
structure contained in the connection_struct.

instead of either sysv or mmap shared memory or lock files.
this means we can now completely remove
locking_shm.c
locking_slow.c
shmem.c
shmem_sysv.c
and lots of other things also got simpler
locking.c got a bit larger, but is much better compartmentalised now

SOFF_T() macro for setting an SMB_OFF_T variable
also limited mmap based reads to MAX_MMAP_SIZE. We really can't mmap
2^50 bytes due to virtual address space problems.

Problems were just dumb bugs like (defining sys_lseek to return 'int' DOH !).

Got 'religion' about using size_t and ssize_t for read/write stuff
as part of the code to expose 64 bits to the client.
This checkin does all the 'easy' stuff - such as all the read/write/lock
calls - but now comes the harder parts (open & friends) and all the
file enquiry functions.....

to check for stat64 and friends, and then changes much of Samba
to use the data type SMB_OFF_T for file size information.
stat/fstat/lstat/lseek/ftruncate have now become sys_stat etc. to hide
the 64 bit calls if needed.
Note that this still does not expose 64 bit functionality to the
client, as the changes to the reply_xxx smb's are not yet done.
This code change should make these changes possible.
Still to do before full 64 bit-ness to the client:
fcntl lock code.
statfs code
widening of dev_t and ino_t (now possible due to SMB_DEV_T and SMB_OFF_T
types being in place).
Let me know if wierd things happen after this check-in and I'll
fix them :-).

bit file interface for the NT SMB's.
Created a new define, SMB_STRUCT_STAT that currently is
defined to be struct stat - this wil change to a user
defined type containing 64 bit info when the correct
wrappers are written for 64 bit stat(), fstat() and lstat()
calls.
Also changed all sys_xxxx() calls that were previously just
wrappers to the same call prefixed by a dos_to_unix() call
into dos_xxxx() calls. This makes it explicit when a pathname
translation is being done, and when it is not.
Now, all sys_xxx() calls are meant to be wrappers to mask
OS differences, and not silently converting filenames on
the fly.

server.c without breaking things.
this splits off netprot.c and fileio.c for negprot and read/write/seek
handling respectively.
