And this reject is ok, as it is not bug provoking. Other families (PF_IPX, PF_X25, PF_AX25, PF_ATMPVC, PF_APPLETALK) are notallowed for sockets within VE as they are not virtualized. The problem is function vz_security_proto_check prevents creating sockets withfamily=PF_INET/PF_INET6 type=SOCK_RAW protocol=(something except IP, UDP,TCP, ICMP, RAW) which are valid according to source. Patch splits vz_security_proto_check into 2 separate checks: 1) family checkvz_security_family_check and 2) protocol check vz_security_protocol_check.First one checks is the family value allowed in __sock_create, second one -checks if created socket contains the correct (virtualized) protocol.vz_security_protocol_check is placed inside create functions inet_create andinet6_create. This change will allow to create any socket within VE with typeSOCK_RAW for any protocol that is not implemented in kernel and encapsulatesits packets into IP packet (for example VRRP protocol).
