2009-04-14Convert Samba3 to use the common lib/util/charset APIAndrew Bartlett1-7/+7
This removes calls to push_*_allocate() and pull_*_allocate(), as well as convert_string_allocate, as they are not in the common API To allow transition to a common charcnv in future, provide Samba4-like strupper functions in source3/lib/charcnv.c (the actual implementation remains distinct, but the API is now shared) Andrew Bartlett
2009-04-14Solve some of the conflict between Samba3 and Samba4 push_stringAndrew Bartlett1-3/+3
This renames push_string in Samba3 into push_string_base and push_string_check for the two different use cases. This should allow push_string to be imported from Samba4, using it's calling conventions.

2008-05-20Cleanup size_t return values in callers of convert_string_allocateTim Prouty1-6/+6
This patch is the second iteration of an inside-out conversion to cleanup functions in charcnv.c returning size_t == -1 to indicate failure. (This used to be commit 6b189dabc562d86dcaa685419d0cb6ea276f100d)

2007-10-10r1492: Rework our random number generation system.Andrew Bartlett1-3/+3
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(). Andrew Bartlett (This used to be commit 36741d3cf53a7bd17d361251f2bb50851cdb035f)

with more correct NTLMSSP support in client and server, but it will do for now. Also implement LANMAN password only in the classical session setup code, but #ifdef'ed out. In Samba4, I'll make this run-time so we can torture it. Lanman passwords over 14 dos characters long could be considered 'invalid' (they are truncated) - so SMBencrypt now returns 'False' if it generates such a password.

another NTLMv2 combination. We should allow the NTLMv2 response to be calculated with either the domain as supplied, or the domain in UPPER case (as we always did in the past). As a client, we always UPPER case it (as per the spec), but we also make sure to UPPER case the domain, when we send it. This should give us maximum compatability.

As well as avoiding DOS charset issues, this scheme returns useful error codes, that we can map back via the pam interface. This patch also cleans up the interfaces used for password buffers, to avoid duplication of code. Andrew Bartlett (This used to be commit 2a2b1f0c872d154fbcce71a250e23dfad085ba1e)
2003-12-17Make sure we correctly generate the lm session key.Gerald Carter1-0/+20
This fixes a problem joining a Samba domain from a vanilla win2k client that doesn't set the NTLMSSP_NEGOTIATE_NTLM2 flag. Reported on samba ml as "decode_pw: incorrect password length" when handling a samr_set_userinfo(23 or 24) RPC. (This used to be commit ef4ab8d7c497e4229d0c1deeb20d05c95bd8feb9)
2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-3/+3
- 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... (This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)

2003-08-14Change Samba to always use extended security for it's guest logins, (ie,Andrew Bartlett1-1/+1
NTLMSSP with "" username, NULL password), and add --machine-pass (-P) to all of Samba's clients. When connecting to an Active Directory DC, you must initiate the CIFS level session setup with Kerberos, not a guest login. If you don't, your machine account is demoted to NT4. Andrew Bartlett (This used to be commit 3547cb3def45a90f99f67829a533eac1ccba5e77)
2003-07-14Jeremy requested that I get my NTLMSSP patch into CVS. He didn't requestAndrew Bartlett1-0/+31
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) Andrew Bartlett (This used to be commit 5472ddc9eaf4e79c5b2e1c8ee8c7f190dc285f19)
2003-05-09Finally get NTLMv2 working on the client!Andrew Bartlett1-28/+84
With big thanks to tpot for the ethereal disector, and for the base code behind this, we now fully support NTLMv2 as a client. In particular, we support it with direct domain logons (tested with ntlm_auth --diagnostics), with 'old style' session setups, and with NTLMSSP. In fact, for NTLMSSP we recycle one of the parts of the server's reply directly... (we might need to parse for unicode issues later). In particular, a Win2k domain controller now supplies us with a session key for this password, which means that doman joins, and non-spnego SMB signing are now supported with NTLMv2!

key, so we can test it in ntlm_auth. I suspect the 'lm' version doesn't exist, but it's easy to change back. Andrew Bartlett (This used to be commit 5efd95622c411f123660b6613b86c7a68bba68e8)
2003-03-18Merge from HEAD:Andrew Bartlett1-99/+1
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). Andrew Bartlett (This used to be commit 1c87be7a3d127201a6ab78d22d17c971af16b86b)
