info is not initialized here.

I'd recommend to do a in-place initialization here (violating style(9)) for the statically defined field .rti_flags, which implicitly zeroes all other fields.

To explain the comment above about struct initialization here.

struct sockaddr_in mask = {};
struct sockaddr_in sin = { .sin_family = AF_INET, .sin_len = sizeof(sin) };

However, we use things like info.rti_info[RTAX_DST] which I'm not sure if it can be statically assigned.
