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.

read-only open on a directory was done and return an EISDIR from open_file().
Changed interface to fd_close to return error.

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
(This used to be commit d1827a3648009fd0a0d165055015d9aeda7a1037)

Synopsis: change every disk access function to work through a vfs_ops
structure contained in the connection_struct.
(This used to be commit 3aad500c0fb61232ed3431ff4b743b5d18ec852f)

the last piece was to use a smb timeout slightly larger than the
locking timeout in bloking locks to prevent a race
(This used to be commit 1b54cb4a33a65e62c2e3189b78ef073869a60c75)

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

pdus, and then feeds them over either a "local" function call or a "remote"
function call to an msrpc service. the "remote" msrpc daemon, on the
other side of a unix socket, then calls the same "local" function that
smbd would, if the msrpc service were being run from inside smbd.
this allows a transition from local msrpc services (inside the same smbd
process) to remote (over a unix socket).
removed reference to pipes_struct in msrpc services. all msrpc processing
functions take rpcsrv_struct which is a structure containing state info
for the msrpc functions to decode and create pdus.
created become_vuser() which does everything not related to connection_struct
that become_user() does.
removed, as best i could, connection_struct dependencies from the nt spoolss
printing code.
todo: remove dcinfo from rpcsrv_struct because this stores NETLOGON-specific
info on a per-connection basis, and if the connection dies then so does
the info, and that's a fairly serious problem.
had to put pretty much everything that is in user_struct into parse_creds.c
to feed unix user info over to the msrpc daemons. why? because it's
expensive to do unix password/group database lookups, and it's definitely
expensive to do nt user profile lookups, not to mention pretty difficult
and if you did either of these it would introduce a complication /
unnecessary interdependency. so, send uid/gid/num_groups/gid_t* +
SID+num_rids+domain_group_rids* + unix username + nt username + nt domain
+ user session key etc. this is the MINIMUM info identified so far that's
actually implemented. missing bits include the called and calling
netbios names etc. (basically, anything that can be loaded into
standard_sub() and standard_sub_basic()...)

Modified invocations of fd_attempt_close as it now takes a fsp instead
of a fd.

don't have the ALLOW_DELETE_ON_CLOSE share flag enabled. Told you
this was fiddly code :-).

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.
Jeremy.

I have tested it by creating a 'holey' 20GB file - checking that
it shows up correctl in the NT file view (it does) and am busily
copying it to NULL: on the NT box. All good so far.... :-).
Also implemented NT 'delete on close' semantics.

Added "nt smb support" parameter to allow NT SMB's to be turned off.

include/smb.h: Moved old typedefs of uint8 etc. into include/includes.h where
all the other defines live (changed them from typedefs to
defines).
Other changes : changed from using uint32 to SMB_DEV_T and SMB_INO_T
in preparation for moving to size independed (ie. 64 bit clean) device
and inode access. Stat call wrapper comes next :-).
Jeremy.

chain_fsp on close (if you don't know what this means, consider yourself

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.
