David S. Miller 951e07c930 [IPV4]: Fix byte value boundary check in do_ip_getsockopt(). ... This fixes kernel bugzilla 10371. As reported by M.Piechaczek@osmosys.tv, if we try to grab a char sized socket option value, as in: unsigned char ttl = 255; socklen_t len = sizeof(ttl); setsockopt(socket, IPPROTO_IP, IP_MULTICAST_TTL, &ttl, &len); getsockopt(socket, IPPROTO_IP, IP_MULTICAST_TTL, &ttl, &len); The ttl returned will be wrong on big-endian, and on both little- endian and big-endian the next three bytes in userspace are written with garbage. It's because of this test in do_ip_getsockopt(): if (len < sizeof(int) && len > 0 && val>=0 && val<255) { It should allow a 'val' of 255 to pass here, but it doesn't so it copies a full 'int' back to userspace. On little-endian that will write the correct value into the location but it spams on the next three bytes in userspace. On big endian it writes the wrong value into the location and spams the next three bytes. Signed-off-by: David S. Miller <davem@davemloft.net>		2008-04-10 01:29:36 -07:00
