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 :-).

(This used to be commit 1d710d06a2)
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 f650e3bdaf)
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.
