+Subject: [PATCH] Avoid redefinition of struct ethhdr
+
+This is a workaround to the if_ether.h conflict between musl and the kernel.
+Both define struct ethhdr.

+Subject: [PATCH] in dns parsing callback, enforce MAXADDRS to preclude
+ overflow
+
+MAXADDRS was chosen not to need enforcement, but the logic used to
+compute it assumes the answers received match the RR types of the
+queries. specifically, it assumes that only one replu contains A
+record answers. if the replies to both the A and the AAAA query have
+their answer sections filled with A records, MAXADDRS can be exceeded
+and clobber the stack of the calling function.
+
+this bug was found and reported by Felix Wilhelm.
