Olivier Matz b9aa52c4cb ipv6: fix EFAULT on sendto with icmpv6 and hdrincl ... The following code returns EFAULT (Bad address): s = socket(AF_INET6, SOCK_RAW, IPPROTO_ICMPV6); setsockopt(s, SOL_IPV6, IPV6_HDRINCL, 1); sendto(ipv6_icmp6_packet, addr); /* returns -1, errno = EFAULT */ The IPv4 equivalent code works. A workaround is to use IPPROTO_RAW instead of IPPROTO_ICMPV6. The failure happens because 2 bytes are eaten from the msghdr by rawv6_probe_proto_opt() starting from commit 19e3c66b52 ("ipv6 equivalent of "ipv4: Avoid reading user iov twice after raw_probe_proto_opt""), but at that time it was not a problem because IPV6_HDRINCL was not yet introduced. Only eat these 2 bytes if hdrincl == 0. Fixes: 715f504b11 ("ipv6: add IPV6_HDRINCL option for raw sockets") Signed-off-by: Olivier Matz <olivier.matz@6wind.com> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.
