From: Thierry Reding <tred...@nvidia.com> Starting with GNU libc 2.8 and later, the definitions of the in6_pktinfo and ip6_mtuinfo structures is guarded by __USE_GNU. Make sure to provide the structures in the linux/ipv6.h when building against GNU libc 2.8 or later and __USE_GNU is undefined to avoid breaking build issues.
One example where such failure to build can be observed is dhcpcd 6.6.7.
