2003-08-02Correct fix (removed the earlier band-aid) for what I thought was a signingJeremy Allison1-0/+4
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 :-).

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)

2003-03-18Merge from HEAD:Andrew Bartlett1-5/+7
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)

2001-08-27converted smbd to use NTSTATUS by defaultAndrew Tridgell1-0/+3
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 (This used to be commit 83d9896c1ea8be796192b51a4678c2a3b87f7518)

2001-08-10A rewrite of the error handling in the libsmb client code. I've separatedTim Potter1-1/+0
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. (This used to be commit 6dbdb0d813f3c7ab20b38baa1223b0b479aadec9)

2001-02-20initial client side unicode support (needed for netapp filer)Andrew Tridgell1-1/+17
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.

2000-11-16Ok - fixed a bug in our levelII oplock code. We need to break a level II onJeremy Allison1-1/+10
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/+10
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)
