2001-07-07Add backend encryption support for NTLMv2.Andrew Bartlett1-1/+96
The leg-work for this was done by the folks at samba-tng.org, I'm just bringing it accross to HEAD. The MD5 implementation is seperatly derived, and does not have the copyright problems that the one in TNG has. Also add const to a few places where it makes sence. Andrew Bartlett (This used to be commit 8df8e841445dfe09fc7a06bb55d12adc3fecb345)
2001-07-04The big character set handling changeover!Andrew Tridgell1-30/+11
This commit gets rid of all our old codepage handling and replaces it with iconv. All internal strings in Samba are now in "unix" charset, which may be multi-byte. See internals.doc and my posting to samba-technical for a more complete explanation. (This used to be commit debb471267960e56005a741817ebd227ecfc512a)

2000-10-13last part of W2K support.Jean-François Micouleau1-4/+5
the trust domain list reply on netlogon pipe was wrong, interim hack until we have full trust relationships. changed some unistr2 to parse the ending NULL char. added a prs_align_needed() function. much like a prs_align but with a condition. needed for the unistr2 parsing.

1999-11-21you know what? this sort of thing makes me laugh. hmm, what functionsLuke Leighton1-1/+1
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)
1999-11-19The First Necessary UNICODE String Support.Luke Leighton1-19/+67
the random workstation trust account password is TOTAL garbage. i mean, complete garbage. it's nowhere CLOSE to being a UNICODE string. therefore we can't just take every second character. created nt_owf_genW() which creates NT#(password) instead of NT#(Unicode(pw)). followed through to the password setting in srv_samr.c (This used to be commit 172601b84ae94044b27ded917d4e0e21e47a5a66)

1999-03-19Implemented encryption algorithm used for a number of RPC buffers.Matthew Chapman1-0/+45
(actually, decryption only currently because I need to get some sleep). Basically another Microsoft twist on DES; the "master key" is the user's NT hash MD4'd and subsets of this are chosen as the 56-bit DES keys. (This used to be commit f09388fa6f41a13ca035b5b2ff40be804608f619)
1999-02-12UNICODE cleanup (see lib/util_unistr.c).Matthew Chapman1-1/+1
No more ugly static library buffers and all functions take a destination string length (especially unistrcpy was rather dangerous; we were only saved by the fact that datagrams are limited in size). (This used to be commit a1d39af1ce1d451b811dbd7c2ba391214851b87e)

1998-11-12largely rewrote smbpasswd so that the code is understandable. ThisAndrew Tridgell1-1/+1
should allow us to call a function in swat rather than piping to smbpasswd. while doing this I also fixed quite a few "const char *" versus "char *" issues that cropped up while using const to track down bugs in the code. This led to changes in several generic functions. The smbpasswd changes should be correct but they have not been extensively tested. At least if I have introduced bugs then we should be able to fix them more easily than before. (This used to be commit 713864dd0322ae2ae2d83e333d85be35a7eed4ec)
1998-10-19- dce/rpc codeLuke Leighton1-1/+1
- removed debug info in struni2 and unistr2 (security risk) - rpc_pipe function was getting pointer to data then calling realloc *dur* - password check function, the start of "credential checking", user, wks, domain, pass as the credentials (not just user,pass which is incorrect in a domain context) - cli_write needs to return ssize_t not size_t, because total can be -1 if the write fails. - fixed signed / unsigned warnings (how come i don't get those any more when i compile with gcc???) - nt password change added in smbd. yes, jeremy, i verified that the SMBtrans2 version still works.

1998-10-02- static function "create_new_hashes" was identical to "nt_lm_owf_gen".Luke Leighton1-10/+36
create_new_hashes didn't zero the buffer for the md4hash: nt_lm_owf_gen did, because jeremy sorted this out a couple of days ago. call nt_lm_owf_gen instead. - call SMBOWFencrypt from SMBencrypt and SMBNTencrypt. - added #ifdef DEBUG_PASSWORD debug password calls. (This used to be commit a4e7cc3e46b713aa0ae55de74a1c70921bef578d)

1998-09-05tridge the destroyer returns!Andrew Tridgell1-23/+0
prompted by the interpret_security() dead code that Jean-Francois pointed out I added a make target "finddead" that finds potentially dead (ie. unused) code. It spat out 304 function names ... I went through these are deleted many of them, making others static (finddead also reports functions that are used only in the local file). in doing this I have almost certainly deleted some useful code. I may have even prevented compilation with some compile options. I apologise. I decided it was better to get rid of this code now and add back the one or two functions that are needed than to keep all this baggage. So, if I have done a bit too much "destroying" then let me know. Keep the swearing to a minimum :) One bit I didn't do is the ubibt code. Chris, can you look at that? Heaps of unused functions there. Can they be made static? (This used to be commit 2204475c87f3024ea8fd1fbd7385b2def617a46f)
1998-01-22This is *not* a big change (although it looks like one).Jeremy Allison1-1/+1
This is merely updating the Copyright statements from 1997 to 1998. It's a once a year thing :-). NO OTHER CHANGES WERE MADE. Jeremy. (This used to be commit b9c16977231efb274e08856f7f3f4408dad6d96c)

1997-11-09attempting to mark up 32 bit error codes, needed for NT domains.Luke Leighton1-6/+16
separated out smb server-mode password validation into a separate file. added called and calling netbios names to client gen state: referenced section in rfc1002.txt. created workstation trust account checking code in ntclient.c there might be a bug in reply_session_setup_andX. i indented and added { } around single-line if statements: the lm password checking code now doesn't look right (around the GUEST_SESSSETUP bits). *no code semantics have been changed by the indentation process*.

in clientutil.c (Luke, you can't just copy a global variable declaration from one file to another, you need to declare one of them extern) (This used to be commit 944ecbcbd47afcc20e2e408a06d57c7b8d0d86a8)
1997-10-25Makefile :Luke Leighton1-0/+24
adding bits for new nt domain code byteorder.h : trying to get macros right, and not to crash on SUNOS5... client.c : added #ifdef NTDOMAIN, and created do_nt_login() function. don't want to have to recompile client.c unless absolutely necessary. credentials.c : moved deal_with_creds() [possibly inappropriately] into credentials.c ipc.c reply.c server.c uid.c : attempting to make (un)become_root() functions calleable from smbclient. this is a little tricky: smbclient might have to be another setuid root program, immediately setuid'ing to non-root, so that we can reset-uid to root to get at the smbpasswd file. or, have a secure pipe mechanism to smbd to grab smbpasswd entries. or the like. smbdes.c smbencrypt.c : created a function to generate lm and nt owf hashes. lsaparse.c ntclient.c smbparse.c : added nt client LSA_AUTH2 code. it works, too! pipenetlog.c pipentlsa.c pipesrvsvc.c : simplification. code-shuffling. getting that damn offset right for the opcode in RPC_HDR. smb.h : changed dcinfo xxx_creds to DOM_CRED structures instead of DOM_CHAL. we might need to store the server times as well. proto.h : the usual. (This used to be commit 82436a3d99d4bdce249ce9ff27fd2ca4b2447e07)
1997-09-16- change generate_challenge() to use md4 instead of desAndrew Tridgell1-23/+0
- move routines about a bit between smbencrypt.c and smbdes.c. Ensure that there is no entry point for normal DES operation - add the following comment: This code is NOT a complete DES implementation. It implements only the minimum necessary for SMB authentication, as used by all SMB products (including every copy of Microsoft Windows95 ever sold) In particular, it can only do a unchained forward DES pass. This means it is not possible to use this code for encryption/decryption of data, instead it is only useful as a "hash" algorithm. There is no entry point into this code that allows normal DES operation. I believe this means that this code does not come under ITAR regulations but this is NOT a legal opinion. If you are concerned about the applicability of ITAR regulations to this code then you should confirm it for yourself (and maybe let me know if you come up with a different answer to the one above) (This used to be commit 35b92e725f351c9a9f2846a6b55f71c234f187c7)
1997-09-15rewrote md4.c from scratch. This implementation should be portable andAndrew Tridgell1-14/+5
doesn't have any worries about RSA copyright. (This used to be commit a1569971663f01c245c145b18290d9dba965dc36)
1997-09-14This commit does 3 main things:Andrew Tridgell1-63/+10
1) put the encryption code in by default, with no #ifdef. It is still disabled by default so you need to add "encrypt passwords = yes" in smb.conf but at least all binaries will have it. 2) cleanup the kanji code so it compiles with no warnings 3) get rid of lots of uses of ugly non-portable C code. The main offender being things like "register" but also remove uses of the "const" keyword as there are compilers out there that don't support it and even those that do often complain about its usage. Users don't like warnings :-( There is still some work to do. We need to replace the md4 code with our own implementation. The current code (from rfc1186) is PD but is not very portable. The new RFC (rfc1320) is more portable but adds copyright restrictions. I'll do a from-scratch MD4 soon. We also need to test that what I've implemented is portable. It should be, but I'm too tired right now to test it on anything other than intel linux. (This used to be commit db917c62c14315afe6f0745a8097c1bca25cbf07)
