2007-10-10r17292: Try and fix bug #3967 - signing problems on transJeremy Allison1-40/+61
calls introduced by signing code simplification. Please test if you've seen signing problems with 3.0.23a. Jeremy. (This used to be commit f462daf02c12cfba634f92e681eb23a09e7d0acf)
2007-10-10r15018: Merge Volker's ipc/trans2/nttrans changes overJeremy Allison1-36/+2
into 3.0. Also merge the new POSIX lock code - this is not enabled unless -DDEVELOPER is defined. This doesn't yet map onto underlying system POSIX locks. Updates vfs to allow lock queries. Jeremy. (This used to be commit 08e52ead03304ff04229e1bfe544ff40e2564fc7)
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)
2007-10-10r10656: BIG merge from trunk. Features not copied overGerald Carter1-4/+15
* \PIPE\unixinfo * winbindd's {group,alias}membership new functions * winbindd's lookupsids() functionality * swat (trunk changes to be reverted as per discussion with Deryck) (This used to be commit 939c3cb5d78e3a2236209b296aa8aba8bdce32d3)

2007-10-10r5840: Fix findfirst/findnext with protocol level < NT1.Jeremy Allison1-2/+3
Jeremy. (This used to be commit d53b5891a7d372b3ed2488bac06939d29388f709)
2007-10-10r4570: Replace cli->nt_pipe_fnum with an array of NT file numbers, one for eachVolker Lendecke1-2/+2
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)
2007-10-10r4088: Get medieval on our ass about malloc.... :-). Take control of all our ↵Jeremy Allison1-4/+4
allocation functions so we can funnel through some well known functions. Should help greatly with malloc checking. HEAD patch to follow. Jeremy. (This used to be commit 620f2e608f70ba92f032720c031283d295c5c06a)
2003-12-01Ensure we use the same mid for the secondary trans requests, W2K3Jeremy Allison1-0/+6
does this. Jeremy. (This used to be commit 8adf0cd27a23b1bc6e0da08789a8b1e9eefb54a7)

2003-11-30Fix signing bug with secondary client trans requests. Turns out the lastJeremy Allison1-0/+20
packet is the one that matters for checking the signing replies. Need to check the server code does this correctly too.... Bug #832 reported by Volker. Jeremy. (This used to be commit 6750dc33b46c422582176b704592d9b2f1fb04d7)
2003-10-20We are doing NT error codes now.... If we have an NT error, report thatVolker Lendecke1-0/+11
back the same way we handle the DOS error. Although I don't see why BUFFER_TOO_SMALL should not be handled as an error, simply copy the logic. This is only called from smbcacls and smbcquotas. Volker (This used to be commit 169f4dfee08e8de05e729fd48209df91cf8ba255)
2003-08-02More fixes for client and server side signing. Ensure sequence numbersJeremy Allison1-17/+61
are updated correctly on returning an error for server trans streams. Ensure we turn off client trans streams on error. Jeremy. (This used to be commit 3a789cb7f01115c37404e5a696de363287cb0e5f)
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 :-). Jeremy. (This used to be commit 2093a3130d4087d0659b497eebd580e7a66e5aa3)
2003-03-17Merge from HEAD:Andrew Bartlett1-3/+3

2002-01-30Removed version number from file header.Tim Potter1-2/+1
Changed "SMB/Netbios" to "SMB/CIFS" in file header. (This used to be commit 6a58c9bd06d0d7502a24bf5ce5a2faf0a146edfa)
2002-01-11Same fix as went into 2.2 (I'm waiting for jerry to finish some code).Jeremy Allison1-4/+4

2001-09-05use cli_is_error() instead of looking in smb_rcls, otherwise NT statusAndrew Tridgell1-2/+2
codes don't work correctly (This used to be commit 55d5828e608671f070a9e96938be0d16d50aeb26)
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)
2001-08-20a bunch of fixes from the sflight to seattleAndrew Tridgell1-7/+10
in particular: - fixed NT status code for a bunch of ops - fixed handling of protocol levels in ms_fnmatch (This used to be commit 3eba9606f71f90bfd9820af26f8676277ed22390)

2001-08-12this is a big global fix for the ptr = Realloc(ptr, size) bug.Simo Sorce1-4/+26
many possible mem leaks, and segfaults fixed. someone should port this fix to 2.2 also. (This used to be commit fa8e55b8b465114ce209344965c1ca0333b84db9)
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)
2001-07-04The big character set handling changeover!Andrew Tridgell1-1/+1
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)
