+Subject: [PATCH] Add missing <limits.h> include
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+key.dns_resolver.c uses ‘UINT_MAX’ and ‘ULONG_MAX’, but forgets to
+include <limits.h>, which causes build failure with certain C
+libraries (notably the musl C library).
