2007-10-10r14146: Just some typos.Günther Deschner1-2/+2

2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-19/+20
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)

2007-10-10r6014: rather large change set....Gerald Carter1-39/+42
pulling back all recent rpc changes from trunk into 3.0. I've tested a compile and so don't think I've missed any files. But if so, just mail me and I'll clean backup in a couple of hours. Changes include \winreg, \eventlog, \svcctl, and general parse_misc.c updates. I am planning on bracketing the event code with an #ifdef ENABLE_EVENTLOG until I finish merging Marcin's changes (very soon). (This used to be commit 4e0ac63c36527cd8c52ef720cae17e84f67e7221)

2007-10-10r1492: Rework our random number generation system.Andrew Bartlett1-1/+1
On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork(). For other systems, we now only re-seed after a fork, and on startup. No need to do it per-operation. This removes the 'need_reseed' parameter from generate_random_buffer(). Andrew Bartlett (This used to be commit 36741d3cf53a7bd17d361251f2bb50851cdb035f)
2007-10-10r1202: This hopefully fixes our memory use when unmarshalling strings. The ↵Volker Lendecke1-1/+4
test case was 'rpcclient -c "enumprinters 2"' with 4000 printers. At some point this completely exploded in memory usage. For every string we talloc'ed memory up to the end of the buffer. -> O(n^2). This survives valgrind with this number of printers. It might also have influence on winbind with a large number of users. All those who dare to look at samba3 rpc code, could you please take a look? I know this is a burden, but I would like comments ;-))) Volker (This used to be commit af251f4ea63c584604972e1c8add83e65046de80)

2003-07-14Jeremy requested that I get my NTLMSSP patch into CVS. He didn't requestAndrew Bartlett1-95/+175
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)
