- Re-disable tdbtool (it was building fine on my Debian box but other
machines were having problems)
(This used to be commit 0d7bb2c40b7a9ed59df3f8944133ea562697e814)
outstanding async operation (triggering an immediate timeout).
pvfs now passes the RAW-MUX test
(This used to be commit 3423e2f41461d054067ef168b9b986f62cc8f77c)
deferred reply is short-circuited immediately when the file is
closed by another user, allowing it to be opened by the waiting user.
- added a sane set of timeval manipulation routines
- converted all the events code and code that uses it to use struct
timeval instead of time_t, which allows for microsecond resolution
instead of 1 second resolution. This was needed for doing the pvfs
deferred open code, and is why the patch is so big.
(This used to be commit 0d51511d408d91eb5f68a35e980e0875299b1831)
the idea is that a passthru module can use ntvfs_async_state_push() before
calling ntvfs_next_*() and in the _send function it calls
ntvfs_async_state_pop() and then call the upper layer send_fn itself
- ntvfs_nbench is now fully async
- the ntvfs_map_*() functions and the trans(2) mapping functions are not converted yet

server shutdown we don't want a synchronous operation which may block
to be called, thus delaying the shutdown.
(This used to be commit 5882f7305fa850c39088e85eefd311c8ede15597)
the ntvfs_generic mapping functions rather than sending the exact
function asked for. This allows the generic mapping functions to be
tested by comparing the behaviour of smbtorture against two cifs
backend shares, one using "cifs:mapgeneric = true" and the other
"cifs:mapgeneric = False"
(This used to be commit c240c6bca5e10f1acbff45b0ed41c4c1ebcaae96)
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.
(This used to be commit 3457c1836c09c82956697eb21627dfa2ed37682e)
in the right state when called. For example, when we use the unixuid
handler in the chain of handlers, and a backend decides to continue a
call asynchronously then we need to ensure that the continuation
happens with the right security context.
The solution is to add a new ntvfs operation ntvfs_async_setup(),
which calls all the way down through the layers, setting up anything
that is required, and takes a private pointer. The backend wanting to
make a async calls can use ntvfs_async_setup() to ensure that the
modules above it are called when doing async processing.
(This used to be commit a256e71029727fa1659ade6257085df537308c7d)
- 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)

rather than manual reference counts
- properly support SMBexit in the cifs and posix backends
- added a logoff method to all backends
With these changes the RAW-CONTEXT test now passes against the posix backend
(This used to be commit c315d6ac1cc40546fde1474702a6d66d07ee13c8)
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.
(This used to be commit f84c0af35cb54c8fdc4933afefc18fa4c062aae4)
Up to now the client code has had an async API, and operated
asynchronously at the packet level, but was not truly async in that it
assumed that it could always write to the socket and when a partial
packet came in that it could block waiting for the rest of the packet.
This change makes the SMB client library full async, by adding a
separate outgoing packet queue, using non-blocking socket IO and
having a input buffer that can fill asynchonously until the full
packet has arrived.
The main complexity was in dealing with the events structure when
using the CIFS proxy backend. In that case the same events structure
needs to be used in both the client library and the main smbd server,
so that when the client library is waiting for a reply that the main
server keeps processing packets. This required some changes in the
events library code.
Next step is to make the generated rpc client code use these new
capabilities.
(This used to be commit 96bf4da3edc4d64b0f58ef520269f3b385b8da02)
the idea is to have services as modules (smb, dcerpc, swat, ...)
the process_model don't know about the service it self anymore.
TODO:
- the smbsrv should use the smbsrv_send function
- the service subsystem init should be done like for other modules
- we need to have a generic socket subsystem, which handle stream, datagram,
and virtuell other sockets( e.g. for the ntvfs_ipc module to connect to the dcerpc server
, or for smb or dcerpc or whatever to connect to a server wide auth service)
- and other fixes...
NOTE: process model pthread seems to be broken( but also before this patch!)

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

added ldbedit, a _really_ useful command
added ldbadd, ldbdel, ldbsearch and ldbmodify to build
solved lots of timezone issues, we now pass the torture tests with
client and server in different zones
fixed several build issues
I know this breaks the no-LDAP build. Wait till I arrive in San Jose for that
fix.

that conn->ntvfs_private is set correctly, instead use our copy of the
private pointer in the fde callback. This allows the cifs backend to
be used on conjunction with a NTVFS filter module.

Update to the modules system. Fixed:
- get rid of smb_probe_module
- merge older updates from 3.0
- introduced register_subsystem() and register_backend() functions
- adapt ntvfs and charset to use new register functions
- made smb_load_modules() work recursively (e.g. 'preload modules = /usr/lib/samba')
- got rid of some old remains
Things that still need work:
- Did I break tankFS? I don't think so, but I can't test it here :-(
- Add 'postload modules = ' (for modules that need to be loaded after fork() in smbd, if applicable)
- Convert RPC, auth, passdb, etc to use new register_{subsystem,backend}() functions
- Accept wildcards in 'preload modules' option, instead of loading recursively
(This used to be commit 7512b9ab1a8b3103f7a6c13f736353c46a26b668)
- allow username of form DOMAIN\username or DOMAIN/username
- added ntrename to gentest
