to obtain IPv4 next hop address in tablearg case. Add `fwd tablearg' support for IPv6. ipfw(8) uses INADDR_ANY as next hop address in O_FORWARD_IP opcode for specifying tablearg case. For IPv6 we still use this opcode, but when packet identified as IPv6 packet, we obtain next hop address from dedicated field nh6 in struct table_value. Replace hopstore field in struct ip_fw_args with anonymous union and add hopstore6 field. Use this field to copy tablearg value for IPv6. Replace spare1 field in struct table_value with zoneid. Use it to keep scope zone id for link-local IPv6 addresses. Since spare1 was used internally, replace spare0 array with two variables spare0 and spare1. Use getaddrinfo(3)/getnameinfo(3) functions for parsing and formatting IPv6 addresses in table_value. Use zoneid field in struct table_value to store sin6_scope_id value. Since the kernel still uses embedded scope zone id to represent link-local addresses, convert next_hop6 address into this form before return from pfil processing. This also fixes in6_localip() check for link-local addresses. Differential Revision: https://reviews.freebsd.org/D2015 Obtained from: Yandex LLC Sponsored by: Yandex LLC |
