389b700a26 Now that fsp's are created on successful file open, the structure member
fsp->open is no longer needed (if an fsp pointer is valid, then it's open :-).

NB for Luke, this patch also did not apply to TNG. TNG is not yet
identical w.r.t file serving with HEAD. This makes it impossible for
me to help maintain TNG. Please fix asap.

lib/substitute.c: Removed unused variable (pidstr).

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.

204ca1195c locking/locking.c: Fixed placeholder code for POSIX locking.
printing/printing.c: Cast tdb_delete to (tdb_traverse_func) to stop warning.
                     tmpfile gives mirror warning.
smbd/groupname.c: Remember to file_lines_free() on exit.
tdb/tdb.h: Add tdb_traverse_func typedef.

a09470817c converted a bunch more functions to use a fd instead of a FILE*
to support some of this I added the following functions in util_file.c

file_lines_pload : load lines from a pipe
file_pload : load a pipe into memory
-
Andrew Tridgell
ad56e3d791 got rid of all the FILE* calls in the NT print system.
this also fixes a few security holes in that code. JF - you need to be
careful about open files for writing! symlinks can trap you.

note that I always unlink() the file first, then open with
O_EXCL. That is a cheap trick to avoid the symlink problems.

a902caf8d7 the bulk of the changes. Also split the loadparm related code into printing/load.c
so swat can get it without linking to the backend code

------------
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.
-
Andrew Tridgell
e064422af3 rather than doing print file open processing in open.c we now handle
it in print_open_file()

that removes a lot of special cases in open.c and makes the print
handling code much easier to understand.

there is still lots to do in printing.c, but this at least gets
printing separated from the mainline code
-

b260ef7cb1 JF - you might want to look at this patch.
Went through and fixed up all failure possibilities. If something (malloc,
file open etc.) fails, then this code goes through and cleans up all allocated
resources on exit. This is the equivalent of a C++ destuctor for the allocated
structures. We need code to be written like this to pass purify tests.

2b1663ec13 Interim fix for LPRng. If a lpq parsed line start with a space, we skip
it, to prevent false status return value.

b52e92b09d Added replacement functions sys_popen and sys_pclose. These are based
on the glibc source code and are safer than the traditional popen as
they don't use a shell to exec the requested command. Now we have
these functions they can be tightened up (environment etc.) as required
to make a safe popen. It should now be safe to add the environement
variable loading code to loadparm.c

3d6d386375 fix the reply of rpc_alter_context
OpenPrinterEx is now decoding correctly the query
most of the EnumXXX use the new_buffer struct.
check the (un)marshalling return code.

conclusion: still a long way to go. all the client code has to be
rewritten, and I still wonder how to implement correctly the notify stuff.

aa3c659a8d delineation between smb and msrpc more marked. smbd now constructs
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()...)
