ipv6: Fix commit 63d9950b08184e6531adceb65f64b429909cc101 (ipv6: Make v4-mapped bindings consistent with IPv4)
Commit 63d9950b08184e6531adceb65f64b429909cc101
(ipv6: Make v4-mapped bindings consistent with IPv4)
changes behavior of inet6_bind() for v4-mapped addresses so it should
behave the same way as inet_bind().
During this change setting of err to -EADDRNOTAVAIL got lost:
af_inet.c:469 inet_bind()
err = -EADDRNOTAVAIL;
if (!sysctl_ip_nonlocal_bind &&
!(inet->freebind || inet->transparent) &&
addr->sin_addr.s_addr != htonl(INADDR_ANY) &&
chk_addr_ret != RTN_LOCAL &&
chk_addr_ret != RTN_MULTICAST &&
chk_addr_ret != RTN_BROADCAST)
goto out;
af_inet6.c:463 inet6_bind()
if (addr_type == IPV6_ADDR_MAPPED) {
int chk_addr_ret;
/* Binding to v4-mapped address on a v6-only socket
* makes no sense
*/
if (np->ipv6only) {
err = -EINVAL;
goto out;
}
/* Reproduce AF_INET checks to make the bindings consitant */
v4addr = addr->sin6_addr.s6_addr32[3];
chk_addr_ret = inet_addr_type(net, v4addr);
if (!sysctl_ip_nonlocal_bind &&
!(inet->freebind || inet->transparent) &&
v4addr != htonl(INADDR_ANY) &&
chk_addr_ret != RTN_LOCAL &&
chk_addr_ret != RTN_MULTICAST &&
chk_addr_ret != RTN_BROADCAST)
goto out;
