THIS IS INCOMPLETE! I'M ONLY COMMITING IT IN ORDER TO SOLICIT COMMENTS
FROM A FEW PEOPLE. DON'T TAKE THIS AS THE FINAL VERSION YET.
How to use talloc
-----------------
-Please see the separate document, talloc_guide.txt in this
-directory. You _must_ read this if you want to program in Samba4.

Interface Structures
--------------------
In Samba3 many of the core wire structures in the SMB protocol were
never explicitly defined in Samba. Instead, our parse and generation
functions just worked directly with wire buffers. The biggest problem
-with this is that is tied our parse code with out "business logic"
+with this is that is tied our parse code with our "business logic"
much too closely, which meant the code got extremely confusing to
read.
are extremely important differences in the approach that are worth
pointing out.

+In the Samba3 msrpc code we used explicit parse structures for all
msrpc functions. The problem is that we didn't just put all of the
real variables in these structures, we also put in all the artifacts
as well. A good example is the security descriptor strucrure that
*NOT* be in the interface structure.
In Samba3 there were unwritten rules about which variables in a

+structure a high level caller has to fill in and which ones are filled
in by the marshalling code. In Samba4 those rules are gone, because
the redundent artifact variables are gone. The high level caller just
sets up the real variables and the marshalling code worries about
each SMB.
As an example go and have a look at reply_getatr_send() and
-reply_getatr() in smbd/reply.c. Read them? Good.
+reply_getatr() in smb_server/reply.c. Read them? Good.
Notice that reply_getatr() sets up the req->async structure to contain
the send function. Thats how the backend gets to do an async reply, it
The format is:
- TRANSPORT:host:[flags]
+ TRANSPORT:host[flags]
where TRANSPORT is either ncacn_np for SMB or ncacn_ip_tcp for RPC/TCP
-"host" is an IP or hostname or netbios name
+"host" is an IP or hostname or netbios name. If the binding string
+identifies the server side of an endpoint, "host" may be an empty
+string.
"flags" can include a SMB pipe name if using the ncacn_np transport or
a TCP port number if using the ncacn_ip_tcp transport, otherwise they
other recognised flags are:
- sign : enable ntlmssp signing
- seal : enable ntlmssp sealing
- connect : enable rpc connect level auth (auth, but no sign or seal)
- validate: enable the NDR validator
- print: enable debugging of the packets
- bigendian: use bigendian RPC
- padcheck: check reply data for non-zero pad bytes
+ sign : enable ntlmssp signing
+ seal : enable ntlmssp sealing
+ spnego : use SPNEGO instead of NTLMSSP authentication
+ krb5 : use KRB5 instead of NTLMSSP authentication
+ connect : enable rpc connect level auth (auth, but no sign or seal)
+ validate : enable the NDR validator
+ print : enable debugging of the packets

- ncacn_ip_tcp:myserver:[1024,sign,seal]
+ ncacn_ip_tcp:myserver[sign,seal]
+ ncacn_ip_tcp:myserver[spnego,seal]
IDEA: Maybe extend UNC names like this?
smbclient //server/share
- smbclient //server/share:[sign,seal,spnego]
+ smbclient //server/share[sign,seal,spnego]
DCERPC Handles
--------------
trans2 and other calls
handle servers that don't have the setattre call in torture
add max file coponent length test and max path len test
+ check for alloc failure in all core reply.c and trans2.c code where
+ allocation size depends on client parameter
+
+case-insenstive idea:
+ all filenames on disk lowercase
+ real case in extended attribute
+ keep cache of what dirs are all lowercase
+ when searching for name, don't search if dir is definately all lowercase
+ when creating file, use dnotify to tell if someone else creates at
+ same time
+
+solve del *.* idea:
+ make mangle cache dynamic size
+ fill during a dir scan
+ setup a timer
+ destroy cache after 30 sec
+ destroy if a 2nd dir scan happens on same dir
