2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-0/+4
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)
2007-10-10r12986: Use d_fprintf(stderr, ...) for any error message in net.Lars Müller1-8/+8
All 'usage' messages are still printed to stdout. Fix some compiler warnings for system() calls where we didn't used the return code. Add appropriate error messages and return with the error code we got from system() or NT_STATUS_UNSUCCESSFUL. (This used to be commit f650e3bdafc4c6bcd7eb4bcf8b6b885b979919eb)
2007-10-10r11511: A classic "friday night check-in" :-). This moves muchJeremy Allison1-2/+2
of the Samba4 timezone handling code back into Samba3. Gets rid of "kludge-gmt" and removes the effectiveness of the parameter "time offset" (I can add this back in very easily if needed) - it's no longer being looked at. I'm hoping this will fix the problems people have been having with DST transitions. I'll start comprehensive testing tomorrow, but for now all modifications are done. Splits time get/set functions into srv_XXX and cli_XXX as they need to look at different timezone offsets. Get rid of much of the "efficiency" cruft that was added to Samba back in the day when the C library timezone handling functions were slow. Jeremy.

2007-10-10r10656: BIG merge from trunk. Features not copied overGerald Carter1-7/+8
* \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)
2007-10-10r4088: Get medieval on our ass about malloc.... :-). Take control of all our ↵Jeremy Allison1-2/+1
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)
2007-10-10r2835: Since we always have -I. and -I$(srcdir) in CFLAGS, we can get rid ofTim Potter1-1/+1
'..' from all #include preprocessor commands. This fixes bugzilla #1880 where OpenVMS gets confused about the '.' characters. (This used to be commit 7f161702fa4916979602cc0295919b541912acd6)

tells me that this should not be expanded, so I implemented net status [sessions|shares] [parseable] Volker (This used to be commit 63d877c6b4786dcddf5f389842f798857be282c0)
