-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] Add musl workaround to the libc-compat.h copy
+
+The libc-compat.h kernel header uses glibc specific macros to solve conflicts
+with libc provided headers. This patch makes libc-compat.h work also for musl
+libc.
+
+Future rebase note: when upstream updates libc-compat.h some additional macro
+definitions will be needed. See the Buildroot iproute2 patch
+package/iproute2/0001-Add-the-musl-workaround-to-the-libc-compat.h-copy.patch.
+
+Signed-off-by: Baruch Siach <baruch@tkos.co.il>
+---
+Upstream status: libc-compat.h is a local copy of a kernel headers. A proper
+musl fix must go to the kernel first.
