c85d9e735c r4570: Replace cli->nt_pipe_fnum with an array of NT file numbers, one for each
supported pipe. Netlogon is still special, as we open that twice, one to do
the auth2, the other one with schannel.

The client interface is completely unchanged for those who only use a single
pie. cli->pipe_idx is used as the index for everything except the "real"
client rpc calls, which have been explicitly converted in my last commit. Next
step is to get winbind to just use a single smb connection for multiple pipes.

2acd084866 r1154: Change default setting for case sensitivity to "auto". If set to auto
then is the client supports it (current clients supported are Samba and
CIFSVFS - detected by the negprot strings "Samba", "POSIX 2" and a bare
"NT LM 0.12" string) then the setting of the per packet flag smb_flag
FLAG_CASELESS_PATHNAMES is taken into account per packet. This allows
the linux CIFS client to use Samba in a case sensitive manner.
Additional command in smbclient "case_sensitive", toggles the
flag in subsequent packets.
Docs to follow.

c4255df992 r76: Fix smbfs problem with Tree Disconnect issued before smbfs starts its work.
We use cli_state.smb_rw_error to pass this specific case into cli_close_connection()
from smbmount as smb_rw_error can have only selected number of states and
it is ignored in cli_close_connection().

Compiled and tested by Lars Mueller from SuSE on x86, x86_64, ppc, ppc64, s390 and
s390x.

e9a7e67e01 Merge from HEAD the SMB signing patch that I developed a couple of weeks
ago.

This patch re-adds support for 'optional' SMB signing.  It also ensures that
we are much more careful about when we enable signing, particularly with
on-the-fly smb.conf reloads.

The client code will now attempt to use smb signing by default, and disable
it if the server doesn't correctly support it.

fcbfc7ad06 Changes all over the shop, but all towards:
- NTLM2 support in the server
 - KEY_EXCH support in the server
 - variable length session keys.

In detail:

 - NTLM2 is an extension of NTLMv1, that is compatible with existing
domain controllers (unlike NTLMv2, which requires a DC upgrade).

 * This is known as 'NTLMv2 session security' *

(This is not yet implemented on the RPC pipes however, so there may
well still be issues for PDC setups, particuarly around password
changes.  We do not fully understand the sign/seal implications of
NTLM2 on RPC pipes.)

This requires modifications to our authentication subsystem, as we
must handle the 'challege' input into the challenge-response algorithm
being changed.  This also needs to be turned off for
'security=server', which does not support this.

- KEY_EXCH is another 'security' mechanism, whereby the session key
actually used by the server is sent by the client, rather than being
the shared-secret directly or indirectly.

- As both these methods change the session key, the auth subsystem
needed to be changed, to 'override' session keys provided by the
backend.

- There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure.  This should help the SPNEGO implementation.

- The 'names blob' in NTLMSSP is always in unicode - never in ascii.
Don't make an ascii version ever.

- The other big change is to allow variable length session keys.  We
have always assumed that session keys are 16 bytes long - and padded
to this length if shorter.  However, Kerberos session keys are 8 bytes
long, when the krb5 login uses DES.

 * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. *

- Add better DEBUG() messages to ntlm_auth, warning administrators of
misconfigurations that prevent access to the privileged pipe.  This
should help reduce some of the 'it just doesn't work' issues.

- Fix data_blob_talloc() to behave the same way data_blob() does when
passed a NULL data pointer.  (just allocate)


REMEMBER to make clean after this commit - I have changed plenty of data structures...

245fbf7efb Used cachegrind to track down some bottlenecks.
Removed calls to clobber_region when not compiling with developer as
they were hiding speed problems.
Added fast path to convert_string() when dealing with ascii -> ascii,
ucs2-le to ascii and ascii to ucs2-le with values <= 0x7F. This
gives a speedup of 22% on my nbench tests.
Next I will do this on convert_string_allocate.

2443f7ffa2 Correct fix (removed the earlier band-aid) for what I thought was a signing
bug with w2k. Turns out that when we're doing a trans/trans2/nttrans call
the MID and send_sequence_number and reply_sequence_number must remain constant.
This was something we got very wrong in earlier versions of Samba. I can now
get a directory listing from WINNT\SYSTEM32 with the older earlier parameters
for clilist.c
This still needs to be fixed for the server side of Samba, client appears to
be working happily now (I'm doing a signed smbtar download of an entire W2K3
image to test this :-).

456f51bcbe Jeremy requested that I get my NTLMSSP patch into CVS. He didn't request
the schannel code, but I've included that anyway. :-)

This patch revives the client-side NTLMSSP support for RPC named pipes
in Samba, and cleans up the client and server schannel code.  The use of the
new code is enabled by the 'sign', 'seal' and 'schannel' commands in
rpcclient.

The aim was to prove that our separate NTLMSSP client library actually
implements NTLMSSP signing and sealing as per Microsoft's NTLMv1 implementation,
in the hope that knowing this will assist us in correctly implementing
NTLMSSP signing for SMB packets.  (Still not yet functional)

This patch replaces the NTLMSSP implementation in rpc_client/cli_pipe.c with
calls to libsmb/ntlmssp.c.  In the process, we have gained the ability to
use the more secure NT password, and the ability to sign-only, instead of
having to seal the pipe connection.  (Previously we were limited to sealing,
and could only use the LM-password derived key).

Our new client-side NTLMSSP code also needed alteration to cope with our
comparatively simple server-side implementation.  A future step is to replace
it with calls to the same NTLMSSP library.

Also included in this patch is the schannel 'sign only' patch I submitted to
the team earlier.  While not enabled (and not functional, at this stage) the
work in this patch makes the code paths *much* easier to follow.  I have also
included similar hooks in rpccleint to allow the use of schannel on *any* pipe.

rpcclient now defaults to not using schannel (or any other extra per-pipe
authenticiation) for any connection.  The 'schannel' command enables schannel
for all pipes until disabled.

This code is also much more secure than the previous code, as changes to our
cli_pipe routines ensure that the authentication footer cannot be removed
by an attacker, and more error states are correctly handled.

(The same needs to be done to our server)

892599fb92 Merge from HEAD:
A much better SMB signing module, that allows for mulitple signing algorithms
and correctly backs down from signing when the server cannot sign the reply.

This also attempts to enable SMB signing on NTLMSSP connections, but I don't
know what NTLMSSP flags to set yet.

This would allow 'client use signing' to be set by default, for server
compatability.  (A seperate option value should be provided for mandetory
signing, which would not back down).

e8e98c9ea0 converted smbd to use NTSTATUS by default
major changes include:

- added NSTATUS type
- added automatic mapping between dos and nt error codes
- changed all ERROR() calls to ERROR_DOS() and many to ERROR_NT()
  these calls auto-translate to the client error code system
- got rid of the cached error code and the writebmpx code

We eventually will need to also:
- get rid of BOOL, so we don't lose error info
- replace all ERROR_DOS() calls with ERROR_NT() calls

but that is too much for one night

2ccfea3de7 A rewrite of the error handling in the libsmb client code. I've separated
out the error handling into a bunch of separate functions rather than all
being handled in one big function.

Fetch error codes from the last received packet:

    void cli_dos_error(struct cli_state *cli, uint8 *eclass, uint32 *num);
    uint32 cli_nt_error(struct cli_state *);

Convert errors to UNIX errno values:

    int cli_errno_from_dos(uint8 eclass, uint32 num);
    int cli_errno_from_nt(uint32 status);
    int cli_errno(struct cli_state *cli);

Detect different kinds of errors:

    BOOL cli_is_dos_error(struct cli_state *cli);
    BOOL cli_is_nt_error(struct cli_state *cli);
    BOOL cli_is_error(struct cli_state *cli);

This also means we now support CAP_STATUS32 as we can decode and understand
NT errors instead of just DOS errors.  Yay!

Ported a whole bunch of files in libsmb to use this new API instead of the
just the DOS error.
