I had previously thought this was unnecessary, as windows doesn't use
standards compliant UTF-16, and for filesystem operations treats bytes
as UCS-2, but Bjoern Jacke has pointed out to me that this means we
don't correctly store extended UTF-16 characters as UTF-8 on
disk. This can be seen with (for example) the gothic characters with
codepoints above 64k.
This commit also adds a LOCAL-ICONV torture test that tests the first
1 million codepoints against the system iconv library, and tests 5
million random UTF-16LE buffers for identical error handling to the
system iconv library.
the lib/iconv.c changes need backporting to samba3
The bug (found by tridge) is that Win2k3 is being tighter about the
NTLMSSP flags. If we don't negotiate sealing, we can't use it.
We now have a way to indicate to the GENSEC implementation mechanisms
what things we want for a connection.

It simplifies our structure handling a lot, making the code shorter
and easier to understand. Look at the diff carefully and see if you
can understand it. If you're still confused then please ask.
This version does the following:
1) talloc_free(), talloc_realloc() and talloc_steal() lose their
(redundent) first arguments
2) you can use _any_ talloc pointer as a talloc context to allocate
more memory. This allows you to create complex data structures
where the top level structure is the logical parent of the next
level down, and those are the parents of the level below
that. Then destroy either the lot with a single talloc_free() or
destroy any sub-part with a talloc_free() of that part
3) you can name any pointer. Use talloc_named() which is just like
talloc() but takes the printf style name argument as well as the
parent context and the size.
The whole thing ends up being a very simple piece of code, although
some of the pointer walking gets hairy.
So far, I'm just using the new talloc() like the old one. The next
step is to actually take advantage of the new interface
properly. Expect some new commits soon that simplify some common
coding styles in samba4 by using the new talloc().
handle connections using the IP as the server name, while not trying
for NBT name resolution on names like "192" and "192.168.1.2".
also removed the ip address argument to smbcli_socket_connect() as it
isn't used and doesn't really make sense.
ALL_INFO queryfileinfo level. It is useful having it here as many
non-Microsoft servers implement it this way, which breaks just about
all the torture tests, so when testing against these broken systems
just change this one #if line and recompile smbtorture.
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 causes our client and server code to use the same core code,
with the same debugs etc.
- In turn, this will allow the 'mandetory/fallback' signing algorithms
to be shared, and only written once.
Updates to the SPNEGO code
- Don't wrap an empty token to the server, if we are actually already finished.

- We can now connect to hosts that follow the SPNEGO RFC, and *do not*
give us their principal name in the mechListMIC.
- The client code now remembers the hostname it connects to
- We now kinit for a user, if there is not valid ticket already
- Re-introduce clock skew compensation
TODO:
- See if the username in the ccache matches the username specified
- Use a private ccache, rather then the global one, for a 'new' kinit
- Determine 'default' usernames.
- The default for Krb5 is the one in the ccache, then $USER
- For NTLMSSP, it's just $USER
Andrew Bartlett
- Spelling - it's SPNEGO, not SPENGO
- SMB signing - Krb5 logins are now correctly signed
- SPNEGO - Changes to always tell GENSEC about incoming packets, empty or not.
