+Subject: [PATCH] lib: check for integer-overflow in nlmsg_reserve()
+
+In general, libnl functions are not robust against calling with
+invalid arguments. Thus, never call libnl functions with invalid
+arguments. In case of nlmsg_reserve() this means never provide
+a @len argument that causes overflow.
+
+Still, add an additional safeguard to avoid exploiting such bugs.
+
+Assume that @pad is a trusted, small integer.
+Assume that n->nm_size is a valid number of allocated bytes (and thus
+much smaller then SIZE_T_MAX).
+Assume, that @len may be set to an untrusted value. Then the patch
+avoids an integer overflow resulting in reserving too few bytes.

+Subject: [PATCH 2/2] build: add Libs.private field in libnl pkg-config file
+
+In order to support static linking, the libnl pkg-config file should
+indicate in its Libs.private field the libraries that libnl-3.0.a
+requires. The LIBS variable contains the appropriate list of
+libraries: -lm in all cases, and -lpthread when pthread support is
+enabled. This allows to statically link applications against libnl
+properly.
