2003-11-22(merge from 3.0)Andrew Bartlett1-2/+2
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... Andrew Bartlett (This used to be commit 57a895aaabacc0c9147344d097d333793b77c947)

2003-03-09Change the way we sign SMB packets, to a function pointer interface.Andrew Bartlett1-6/+7
The intention is to allow for NTLMSSP and kerberos signing of packets, but for now it's just what I call 'simple' signing. (aka SMB signing per the SNIA spec) Andrew Bartlett (This used to be commit b9cf95c3dc04a45de71fb16e85c1bfbae50e6d8f)
2003-02-16Add the 'session key' output of the NTLMSSP exchange to the cli struct, soAndrew Bartlett1-0/+4
it can be used for 'net rpc join'. Also fix a bug in our server-side NTLMSSP code - a client without any domain trust links to us may calculate the NTLMv2 response with "" as the domain. Andrew Bartlett (This used to be commit ddaa42423bc952e59b95362f5f5aa7cca10d1ad4)
2003-02-09(only for HEAD at the moment).Andrew Bartlett1-1/+1
Add NTLMv2 support to our client, used when so configured ('client use NTLMv2 = yes') and only when 'client use spengo = no'. (A new option to allow the client and server ends to chose spnego seperatly). NTLMv2 signing doesn't yet work, and NTLMv2 is not done for NTLMSSP yet. Also some parinoia checks in our input parsing. Andrew Bartlett (This used to be commit 85e9c060eab59c7692198f14a447ad59f05af437)
2003-02-01We now have client-side SMB signing support!Andrew Bartlett1-0/+1
This checking allows us to connect to Microsoft servers the use SMB signing, within a few restrictions: - I've not get the NTLMSSP stuff going - it appears to work, but if you break the sig - say by writing a zero in it - it still passes... - We don't currently verfiy the server's reply - It works against one of my test servers, but not the other... However, it provides an excellent basis to work from. Enable it with 'client signing' in your smb.conf. Doc to come (tomorrow) and this is not for 3.0, till we get it complete. The CIFS Spec is misleading - the session key (for NTLMv1 at least) is the standard session key, ie MD4(NT#). Thanks to jra for the early work on this. Andrew Bartlett (This used to be commit 1a2738937e3d80b378bd0ed33cd8d395fba2d3c3)

2002-06-16Fix up some of the SMB signing code:Andrew Bartlett1-0/+1
The problem was that *all* packets were being signed, even packets before signing was set up. (This broke the session request). This fixes it to be an 'opt in' measure - that is, we only attempt to sign things after we have got a valid, non-guest session setup as per the CIFS spec. I've not tested this against an MS server, becouse my VMware is down, but at least it doesn't break the build farm any more.

2001-02-20initial client side unicode support (needed for netapp filer)Andrew Tridgell1-0/+6
I've currently got this code disabled by default as it is incomplete. You enable it by setting a USE_UNICODE environment variable. Once the support is complete this check will be removed and the CAP_UNICODE capability bit will be the sole determination of whether the client library code uses unicode right now I have converted session_setup and tconx. I will do more fns over the next few days. see clistr.c for the new client side string interface. Luckily it tends to make the code smaller and neater while adding unicode support. (This used to be commit e1a04e621f1c28d8e6e543d43741ca0272e2237f)
2000-11-16Ok - fixed a bug in our levelII oplock code. We need to break a level II onJeremy Allison1-0/+1
a byte range lock (write lock only, but Win2k breaks on read lock also so I do the same) - if you think about why, this is obvious. Also fixed our client code to do level II oplocks, if requested, and fixed the code where we would assume the client wanted level II if it advertised itself as being level II capable - it may not want that. Jeremy. (This used to be commit 213cd0b5192307cd4b0026cae94b2f52fb1b0c02)
2000-07-27Ok - this is a *BIG* change - but it fixes the problems with static stringsJeremy Allison1-0/+2
in the RPC code. This change was prompted by trying to save a long (>256) character comment in the printer properties page. The new system associates a TALLOC_CTX with the pipe struct, and frees the pool on return of a complete PDU. A global TALLOC_CTX is used for the odd buffer allocated in the BUFFERxx code, and is freed in the main loop. This code works with insure, and seems to be free of memory leaks and crashes (so far) but there are probably the occasional problem with code that uses UNISTRxx structs on the stack and expects them to contain storage without doing a init_unistrXX(). This means that rpcclient will probably be horribly broken. A TALLOC_CTX also needed associating with the struct cli_state also, to make the prs_xx code there work. The main interface change is the addition of a TALLOC_CTX to the prs_init calls - used for dynamic allocation in the prs_XXX calls. Now this is in place it should make dynamic allocation of all RPC memory on unmarshall *much* easier to fix. Jeremy. (This used to be commit 0ff2ce543ee54f7364e6d839db6d06e7ef1edcf4)
2000-07-03first pass at merging rpcclient from TNG to HEAD. You can get aGerald Carter1-0/+2
semi-connection and a rpcclient prompt, but no functionality there yet. Will be a few more days on that. The changes to the header files were minor. A few struct's and a few additional fields to existing ones. No deletions. **minimal change necessary** :-) Well, maybe not minimal, but I tried. All other programs compile, link and run ok from what I can tell so I don;t think I broke anything. --jerry (This used to be commit cd7f0b0b91afd3331c0607ba2fcb3ccdd41ecebf)
2000-04-30YIPEE!!!!!Andrew Tridgell1-0/+1
We finally have a perfect emulation of Microsoft wildcard matching. The routine ms_fnmatch() does wildcard matching with all MS wildcards (including the unicode wildcards), and masktest against a NT4 workstation with hundreds of thousands of random exmaples has not found a single error. amazingly it is only about 60 lines of code, but it has taken us years to get it right. I didn't sleep much last night :) (This used to be commit cc9e007cdfdd300189f89e2a55e4234e47fa842d)

1999-12-08ABOUT TIME!!!!!!!!Luke Leighton1-33/+3
damn, this one is bad. started, at least two days ago, to add an authentication mechanism to the smbd<->msrpc redirector/relay, such that sufficient unix / nt information could be transferred across the unix socket to do a become_user() on the other side of the socket. it is necessary that the msrpc daemon inherit the same unix and nt credentials as the smbd process from which it was spawned, until such time as the msrpc daemon receives an authentication request of its own, whereupon the msrpc daemon is responsible for authenticating the new credentials and doing yet another become_user() etc sequence.

1999-11-24ok. *whew*. this is the first completed part of the restructure.Luke Leighton1-6/+14
verified that lsaquery, lsalookupsids work, and found some bugs in the parameters of these commands :-) soo... we now have an lsa_* api that has the same arguments as the nt Lsa* api! cool! the only significant coding difference is the introduction of a user_credentials structure, containing user, domain, pass and ntlmssp flags.

1999-11-21you know what? this sort of thing makes me laugh. hmm, what functionsLuke Leighton1-0/+2
have we got. and what data do we have. hmm.. i wonder what the NTLMv2 user session key can be... hmmm... weell.... there's some hidden data here, generated from the user password that doesn't go over-the-wire, so that's _got_ to be involved. and... that bit of data took a lot of computation to produce, so it's probably _also_ involved... and md4 no, md5? no, how about hmac_md5 yes let's try that one (the other's didn't work) oh goodie, it worked! i love it when this sort of thing happens. took all of fifteen minutes to guess it. tried concatenating client and server challenges. tried concatenating _random_ bits of client and server challenges. tried md5 of the above. tried hmac_md5 of the above. eventually, it boils down to this: kr = MD4(NT#,username,domainname) hmacntchal=hmac_md5(kr, nt server challenge) sess_key = hmac_md5(kr, hmacntchal); (This used to be commit ab174759cd210fe1be888d0c589a5b2669f7ff1e)
