2009-03-19s3:libsmb: always create bytes array in cli_trans codeStefan Metzmacher1-5/+14
Otherwise we return NO_MEMORY without a reason for fragmented trans requests, as talloc_append_blob() returns buf if we append a 0 length blob. When we pass buf = NULL we'll get back NULL and then assume NO_MEMORY... metze
2009-03-19s3:libsmb: fix smb signing for fragmented trans/trans2/nttrans requestsStefan Metzmacher1-23/+7
Before we send the secondary requests we need to remove the old mid=>seqnum mapping and reset cli->mid and make the new mid=>seqnum mapping "persistent". The bug we had in cli_send_trans was this: The first cli_send_smb() incremented cli->mid and the secondary requests used the incremented mid, but as cli->outbuf still had the correct mid, we send the correct mid to the server. The real problem was that the cli_send_smb() function stored the seqnum under the wrong mid. cli_send_nttrans() was totally broken and now follows the same logic as cli_send_trans(). The good thing is that in practice the problem is unlikely to happen, because max_xmit is large enough to avoid secondary requests. metze

2009-01-29Add the strlen to push to smb_bytes_push_str, return the converted sizeVolker Lendecke1-3/+3
The pushed strlen replaces the STR_TERMINATE flag which I personally always find very confusing.
2008-12-19Pass "bytes_alignment" up through cli_request_sendVolker Lendecke1-3/+3
This parameter makes smb_spice_chain add padding before the bytes field

Introduce async_req_is_error() and async_req_simple_recv()

Rename it to trans_oob, it will be used in the server routines.

2008-09-09Add async trans/trans2/nttrans calls to libsmbVolker Lendecke1-0/+701
Logic stolen from Samba4, naturally the specific implementation differs a bit. (This used to be commit 4b8bc5b03d35d563104791c0d8317d9886e4f032)
2008-05-13Fix signing problem in the client with transs requestsVolker Lendecke1-0/+3
This is a different fix than Jeremy put into 3-0-test with 040db1ce85 and other branches with different hashes. Jeremy, I think your fix led to bug 5436, so I reverted your fix. This fixes the original problem I found with the transs requests for large rpc queries in a different way. Please check! Thanks, Volker (This used to be commit c572d537e088a3fffb057181cad9a3692e40b815)

2007-10-10r22732: - Testing of libsmbclient against Vista revealed what is likely a bug inDerrell Lipman1-1/+8
Vista. Vista provides a plethora of kludges to simulate older versions of Windows. The kludges are in the form of shortcuts (or more likely symbolic links, but I don't know enough about Vista to determine that definitively) and in most cases, attempts to access them get back an "access denied" error. On one particular folder, however, "<share>/Users/All Users", it returns an unknown (to ethereal and the Samba3 code) NT status code: 0x8000002d. Although this code does not have a high byte of 0xc0 indicating that it is an error, it appears to be an alternate form of "access denied". Without this patch, libsmbclient times out on an attempt to enumerate that folder rather than returning an error to the caller. This patch corrects that problem. (This used to be commit cc0cd3a12f76b8cd711e3165d4cfe920552f256d)

2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-20/+8
realloc can return NULL in one of two cases - (1) the realloc failed, (2) realloc succeeded but the new size requested was zero, in which case this is identical to a free() call. The error paths dealing with these two cases should be different, but mostly weren't. Secondly the standard idiom for dealing with realloc when you know the new size is non-zero is the following : tmp = realloc(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } However, there were *many* *many* places in Samba where we were using the old (broken) idiom of : p = realloc(p, size) if (!p) { return error; } which will leak the memory pointed to by p on realloc fail. This commit (hopefully) fixes all these cases by moving to a standard idiom of : p = SMB_REALLOC(p, size) if (!p) { return error; } Where if the realloc returns null due to the realloc failing or size == 0 we *guarentee* that the storage pointed to by p has been freed. This allows me to remove a lot of code that was dealing with the standard (more verbose) method that required a tmp pointer. This is almost always what you want. When a realloc fails you never usually want the old memory, you want to free it and get into your error processing asap. For the 11 remaining cases where we really do need to keep the old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR, which can be used as follows : tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the pointer p, even on size == 0 or realloc fail. All this is done by a hidden extra argument to Realloc(), BOOL free_old_on_error which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR macros (and their array counterparts). It remains to be seen what this will do to our Coverity bug count :-). Jeremy. (This used to be commit 1d710d06a214f3f1740e80e0bffd6aab44aac2b0)

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. Volker (This used to be commit dc294c52e0216424236057ca6cd35e1ebf51d0da)

2003-08-02Correct fix (removed the earlier band-aid) for what I thought was a signingJeremy Allison1-0/+18
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 :-).

2001-08-27started converting NTSTATUS to be a structure on systems with gcc in order ↵Andrew Tridgell1-20/+6
to make it type incompatible with BOOL so we catch errors sooner. This has already found a number of bugs (This used to be commit 1b778bc7d22efff3f90dc450eb12baa1241cf68f)
2001-08-27converted smbd to use NTSTATUS by defaultAndrew Tridgell1-12/+17
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 Potter1-9/+15
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)
