-Subject: [PATCH] Avoid undefined behaviour with the ctype(3) functions.
-
-As defined in the C standard:
-
-	In all cases the argument is an int, the value of which shall
-	be representable as an unsigned char or shall equal the value
-	of the macro EOF.  If the argument has any other value, the
-	behavior is undefined.
-
-This is because they're designed to work with the int values returned
-by getc or fgetc; they need extra work to handle a char value.
-
-If EOF is -1 (as it almost always is), with 8-bit bytes, the allowed
-inputs to the ctype(3) functions are:
-
-	{-1, 0, 1, 2, 3, ..., 255}.
-
-However, on platforms where char is signed, such as x86 with the
-usual ABI, code like
-
-	char *arg = ...;
-	... isspace(*arg) ...
-
-may pass in values in the range:
-
-	{-128, -127, -126, ..., -2, -1, 0, 1, ..., 127}.
-
-This has two problems:
-
-1. Inputs in the set {-128, -127, -126, ..., -2} are forbidden.
-
-2. The non-EOF byte 0xff is conflated with the value EOF = -1, so
-   even though the input is not forbidden, it may give the wrong
-   answer.
-
-Casting char to int first before passing the result to ctype(3)
-doesn't help: inputs like -128 are unchanged by this cast.  It is
-necessary to cast char inputs to unsigned char first; you can then
-cast to int if you like but there's no need because the functions
-will always convert the argument to int by definition.  So the above
-fragment needs to be:
-
-	char *arg = ...;
-	... isspace((unsigned char)*arg) ...
-
-This patch inserts unsigned char casts where necessary, and changes
-int casts to unsigned char casts where the input is char.
-
-I left alone int casts where the input is unsigned char already --
-they're not immediately harmful, although they would have the effect
-of suppressing some compiler warnings if the input is ever changed to
-be char instead of unsigned char, so it might be better to remove
-those casts too.
-
-I also left alone calls where the input is int to begin with because
-it came from getc; casting to unsigned char here would be wrong, of
-course.

-Subject: [PATCH] Fix possible SEGV when no servers defined.
-
-If there exists a --address=/<domain>/  or --server=/<domain>/#
-configuration but no upstream server config unqualified by
-domain then when a query which doesnt match the domain is
-recieved it will use the qualfied server config and in the process
-possibly make an out-of-bounds memory access.
-
-Thanks to Daniel Danzberger for spotting the bug.
