20d17b8057 r3081: several updates to ntvfs and server side async request handling in
preparation for the full share modes and ntcreatex code that I am
working on.

highlights include:

 - changed the way a backend determines if it is allowed to process a
   request asynchronously. The previous method of looking at the
   send_fn caused problems when an intermediate ntvfs module disabled
   it, and the caller then wanted to finished processing using this
   function. The new method is a REQ_CONTROL_MAY_ASYNC flag in
   req->control_flags, which is also a bit easier to read

 - fixed 2 bugs in the readbraw server code. One related to trying to
   answer a readbraw with smb signing (which can't work, and crashed
   our signing code), the second related to error handling, which
   attempted to send a normal SMB error packet, when readbraw must
   send a 0 read reply (as it has no header)

 - added several more ntvfs_generic.c generic mapping functions. This
   means that backends no longer need to implement such esoteric
   functions as SMBwriteunlock() if they don't want to. The backend
   can just request the mapping layer turn it into a write followed by
   an unlock. This makes the backends considerably simpler as they
   only need to implement one style of each function for lock, read,
   write, open etc, rather than the full host of functions that SMB
   provides. A backend can still choose to implement them
   individually, of course, and the CIFS backend does that.

 - simplified the generic structures to make them identical to the
   principal call for several common SMB calls (such as
   RAW_WRITE_GENERIC now being an alias for RAW_WRITE_WRITEX).

 - started rewriting the pvfs_open() code in preparation for the full
   ntcreatex semantics.

 - in pvfs_open and ipc_open, initially allocate the open file
   structure as a child of the request, so on error we don't need to
   clean up. Then when we are going to succeed the open steal the
   pointer into the long term backend context. This makes for much
   simpler error handling (and fixes some bugs)

 - use a destructor in the ipc backend to make sure that everthing is
   cleaned up on receive error conditions.

 - switched the ipc backend to using idtree for fnum allocation

 - in the ntvfs_generic mapping routines, use a allocated secondary
   structure not a stack structure to ensure the request pointer
   remains valid even if the backend replies async.

dcad0f6fd4 r2751: this is a new ntvfs design which tries to solve:
- the stacking of modules
- finding the modules private data
- hide the ntvfs details from the calling layer
- I set NTVFS_INTERFACE_VERSION 0 till we are closer to release
  (because we need to solve some async problems with the module stacking)

a3cec511bb r2561: completely redid the ntvfs module chaining code, You can now do something like:
ntvfs handler = nbench posix

and the nbench pass-thru module will be called before the posix
module. The chaining logic is now much saner, and less racy, with each
level in the chain getting its own private pointer rather than relying
on save/restore logic in the pass-thru module.

The only pass-thru module we have at the moment is the nbench one
(which records all traffic in a nbench compatibe format), but I plan
on soon writing a "unixuid" pass-thru module that will implement the
setegid()/setgroups()/seteuid() logic for standard posix uid
handling. This separation of the posix backend from the uid handling
should simplify the code, and make development easier.

I also modified the nbench module so it can do multiple chaining, so
if you want to you can do:

   ntvfs module = nbench nbench posix

and it will save 2 copies of the log file in /tmp. This is really only
useful for testing at the moment until we have more than one pass-thru
module.

118f3edd27 r1291: rename struct smbsrv_context to smbsrv_connection
because this is the connection state per transport layer (tcp)
connection

I also moved the substructs directly into smbsrv_connection,
because they don't need a struct name and we should allway pass the complete
smbsrv_connection struct into functions

579c13da43 r873: converted samba4 to use real 64 bit integers instead of
structures. This was suggested by metze recently.

I checked on the build farm and all the machines we have support 64
bit ints, and support the LL suffix for 64 bit constants. I suspect
some won't support strtoll() and related functions, so we will
probably need replacements for those.

0becf4d683 thanks to ntfsd and some google searches I worked out what the unknown
fields in level 261 and level 262 of directory search are, plus the
names of the levels

the unknown fields are a 64bit unique file id, and match the 64 bit
number from the internal_information qfileinfo level
