Kerberos CCACHE into the system.
This again allows the use of the system ccache when no username is
specified, and brings more code in common between gensec_krb5 and
gensec_gssapi.
It also has a side-effect that may (or may not) be expected: If there
is a ccache, even if it is not used (perhaps the remote server didn't
want kerberos), it will change the default username.

this because I don't want our torture suite to leave behind accounts
with known passwords if it is stopped in the wrong place. It is now
run behind the -X (dangerous) wrapper.

GENSEC, and to pull SCHANNEL into GENSEC, by making it less 'special'.
GENSEC now no longer has it's own handling of 'set username' etc,
instead it uses cli_credentials calls.
In order to link the credentails code right though Samba, a lot of
interfaces have changed to remove 'username, domain, password'
arguments, and these have been replaced with a single 'struct
cli_credentials'.
In the session setup code, a new parameter 'workgroup' contains the
client/server current workgroup, which seems unrelated to the
authentication exchange (it was being filled in from the auth info).
This allows in particular kerberos to only call back for passwords
when it actually needs to perform the kinit.
The kerberos code has been modified not to use the SPNEGO provided
'principal name' (in the mechListMIC), but to instead use the name the
host was connected to as. This better matches Microsoft behaviour,
is more secure and allows better use of standard kerberos functions.
To achieve this, I made changes to our socket code so that the
hostname (before name resolution) is now recorded on the socket.
In schannel, most of the code from librpc/rpc/dcerpc_schannel.c is now
in libcli/auth/schannel.c, and it looks much more like a standard
GENSEC module. The actual sign/seal code moved to
libcli/auth/schannel_sign.c in a previous commit.
The schannel credentails structure is now merged with the rest of the
credentails, as many of the values (username, workstation, domain)
where already present there. This makes handling this in a generic
manner much easier, as there is no longer a custom entry-point.
The auth_domain module continues to be developed, but is now just as
functional as auth_winbind. The changes here are consequential to the
schannel changes.
The only removed function at this point is the RPC-LOGIN test
(simulating the load of a WinXP login), which needs much more work to
clean it up (it contains copies of too much code from all over the
torture suite, and I havn't been able to penetrate its 'structure').

metze needs a working tree...
The main volume of this patch was what I started working on today:
- Cleans up memory handling around DCE/RPC pipes, to have a parent talloc context.
- Uses sepereate inner loops for some of the DCE/RPC tests
The other and more important part of this patch fixes issues
surrounding the new credentials framwork:
This makes the struct cli_credentials always a talloc() structure,
rather than on the stack. Parts of the cli_credentials code already
assumed this.
There were other issues, particularly in the DCERPC over SMB handling,
as well as little things that had to be tidied up before test_w2k3.sh
would start to pass.

I wanted to add a simple 'workstation' argument to the DCERPC
authenticated binding calls, but this patch kind of grew from there.
With SCHANNEL, the 'workstation' name (the netbios name of the client)
matters, as this is what ties the session between the NETLOGON ops and
the SCHANNEL bind. This changes a lot of files, and these will again
be changed when jelmer does the credentials work.
I also correct some schannel IDL to distinguish between workstation
names and account names. The distinction matters for domain trust
accounts.
Issues in handling this (issues with lifetime of talloc pointers)
caused me to change the 'creds_CredentialsState' and 'struct
dcerpc_binding' pointers to always be talloc()ed pointers.
In the schannel DB, we now store both the domain and computername, and
query on both. This should ensure we fault correctly when the domain
is specified incorrectly in the SCHANNEL bind.
In the RPC-SCHANNEL test, I finally fixed a bug that vl pointed out,
where the comment claimed we re-used a connection, but in fact we made
a new connection.
This was achived by breaking apart some of the
dcerpc_secondary_connection() logic.
The addition of workstation handling was also propogated to NTLMSSP
and GENSEC, for completeness.
The RPC-SAMSYNC test has been cleaned up a little, using a loop over
usernames/passwords rather than manually expanded tests. This will be
expanded further (the code in #if 0 in this patch) to use a newly
created user account for testing.
In making this test pass test_rpc.sh, I found a bug in the RPC-ECHO
server, caused by the removal of [ref] and the assoicated pointer from
the IDL. This has been re-added, until the underlying pidl issues are
solved.

less likely that anyone will use pstring for new code
- got rid of winbind_client.h from includes.h. This one triggered a
huge change, as winbind_client.h was including system/filesys.h and
defining the old uint32 and uint16 types, as well as its own
pstring and fstring.

make it possible to add optimisations to the events code such as
keeping the next timed event in a sorted list, and using epoll for
file descriptor events.
I also removed the loop events code, as it wasn't being used anywhere,
and changed timed events to always be one-shot (as adding a new timed
event in the event handler is so easy to do if needed)

dcerpc_alter_context and multiple context_ids in the dcerpc client
library.
This stage does the following:
- split "struct dcerpc_pipe" into two parts, the main part being "struct dcerpc_connection", which
contains all the parts not dependent on the context, and "struct dcerpc_pipe" which has
the context dependent part. This is similar to the layering in libcli_*() for SMB
- disable the current dcerpc_alter code. I've used a #warning until i
get the 2nd phase finished. I don't know how portable #warning is, but
it won't be long before I add full alter context support anyway, so it won't last long
- cleanup the allocation of dcerpc_pipe structures. The previous code
was quite awkward.

Break out the samsync tests from RPC-NETLOGON into a new RPC-SAMSYNC,
that will cross-verify all the values.
Add support for the way netlogon credentials are shared between the
pipe that sets up schannel and the pipe that is encrypted with it.
Test this support, by calling both NETLOGON and SAMR operations in the
RPC-SCHANNEL test.
Move some of the Netlogon NEG flags into the .idl, now we have an idea
what a few of them really are.
Rename the sam_pwd_hash into a name that has meaning (all other crypto
functions were renamed in Samba4 ages ago).
Break out NTLMv2 functionality for operation on the NT hash - I intend
to do NTLMv2 logins in the samsync test in future, and naturally I
only have the hash.

- tidied up some of the system includes
- moved a few more structures back from misc.idl to netlogon.idl and samr.idl now that pidl
knows about inter-IDL dependencies

|

The thing that finally convinced me that minimal includes was worth
pursuing for rpc was a compiler (tcc) that failed to build Samba due
to reaching internal limits of the size of include files. Also the
fact that includes.h.gch was 16MB, which really seems excessive. This
patch brings it back to 12M, which is still too large, but
better. Note that this patch speeds up compile times for both the pch
and non-pch case.
This change also includes the addition iof a "depends()" option in our
IDL files, allowing you to specify that one IDL file depends on
another. This capability was needed for the auto-includes generation.

of associated functions.
The motivation for this change was to avoid having to convert to/from
ucs2 strings for so many operations. Doing that was slow, used many
static buffers, and was also incorrect as it didn't cope properly with
unicode codepoints above 65536 (which could not be represented
correctly as smb_ucs2_t chars)
The two core functions that allowed this change are next_codepoint()
and push_codepoint(). These functions allow you to correctly walk a
arbitrary multi-byte string a character at a time without converting
the whole string to ucs2.
While doing this cleanup I also fixed several ucs2 string handling
bugs. See the commit for details.
The following code (which counts the number of occuraces of 'c' in a
string) shows how to use the new interface:
size_t count_chars(const char *s, char c)
{
size_t count = 0;
while (*s) {
size_t size;
codepoint_t c2 = next_codepoint(s, &size);
if (c2 == c) count++;
s += size;
}
return count;
}

The intial motivation for this commit was to merge in some of the
bugfixes present in Samba3's chrcnv and string handling code into
Samba4. However, along the way I found a lot of unused functions, and
decided to do a bit more...
The strlen_m code now does not use a fixed buffer, but more work is
needed to finish off other functions in str_util.c. These fixed
length buffers hav caused very nasty, hard to chase down bugs at some
sites.
The strupper_m() function has a strupper_talloc() to replace it (we
need to go around and fix more uses, but it's a start). Use of these
new functions will avoid bugs where the upper or lowercase version of
a string is a different length.
I have removed the push_*_allocate functions, which are replaced by
calls to push_*_talloc. Likewise, pstring and other 'fixed length'
wrappers are removed, where possible.
I have removed the first ('base pointer') argument, used by push_ucs2,
as the Samba4 way of doing things ensures that this is always on an
even boundary anyway. (It was used in only one place, in any case).

Rework our random number generation system.
On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork().
For other systems, we now only re-seed after a fork, and on startup.
No need to do it per-operation. This removes the 'need_reseed'
parameter from generate_random_buffer().
This also requires that we start the secrets subsystem, as that is
where the reseed value is stored, for systems without /dev/urandom.
In order to aviod identical streams in forked children, the random
state is re-initialised after the fork(), at the same point were we do
that to the tdbs.

Changes:
- Check for a valid 'pipe_state' in netr_ServerAuthenticate3 before
we dereference it
- removes the expansionroom[7] in the netr_SamInfo* structs to 7
individual elements.
- renames netr_SamInfo -> netr_SamInfo2
netr_SamInfo2 -> netr_SamInfo3
- Having the thing we always called an 'info3' being 'netr_SamInfo2'
was just too confusing.
- Expand and fill in extra details about users from the SAM, into
the server_info, for processing into the SamLogon reply.
- Add a dum_sid_dup() function to duplicate a struct dom_sid
The SamLogon code currently does not return supplementary groups, and is
only tested with Samba4 smbtorture.
