+Subject: [PATCH 2/2] Fix support for uClibc-ng
+
+uClibc-ng is currently at v1.0.9. The patch corrects the uClibc
+version test so that HAVE_IFADDRS_H is defined for uClibc versions
+after v0.9.32.
+
+Submitted upstream to libuv and accepted, see

+Subject: [PATCH 1/2] Fix crash in GetInterfaceAddresses
+
+If uv_interface_addresses() returns UV_ENOSYS then interfaces and count are
+uninitialised. This can cause a segmentation fault inside
+GetInterfaceAddresses when it tries to use the invalid interfaces[]. Fix
+the issue by returning from GetInterfaceAddresses on the UV_ENOSYS error.
+
+This issue was observed when using uCLibc-ng version 1.0.9 because
+uv_interface_addresses() in deps/uv/src/unix/linux-core.c incorrectly
+undefines HAVE_IFADDRS_H.
+
+Submitted upstream, see https://github.com/nodejs/node/pull/4272
