- Fix an abnormal termination caused by twice of "rtadvctl disable". (r224303) - Use poll() to wait for the control message socket instead of a spin loop. (r224304) - s/cmsg_/cm_/ to avoid conflict with CMSG_* symbols for struct cmsghdr. (r224619) - Ignore an interface that never sent RAs for graceful shut-down. (r224620) - Refine log messages. (r225148) - Fix SIGSEGV when receiving RAs that contain RDNSS and/or DNSSL options. (r225149) Approved by: re (kib)
