* payload: explicit network ctx assignment for icmp/icmp6 in special familiesArturo Borrero Gonzalez2017-01-276-0/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the inet, bridge and netdev families, we can add rules like these: % nft add rule inet t c ip protocol icmp icmp type echo-request % nft add rule inet t c ip6 nexthdr icmpv6 icmpv6 type echo-request However, when we print the ruleset: % nft list ruleset table inet t { chain c { icmpv6 type echo-request icmp type echo-request } } These rules we obtain can't be added again: % nft add rule inet t c icmp type echo-request <cmdline>:1:19-27: Error: conflicting protocols specified: inet-service vs. icmp add rule inet t c icmp type echo-request ^^^^^^^^^ % nft add rule inet t c icmpv6 type echo-request <cmdline>:1:19-29: Error: conflicting protocols specified: inet-service vs. icmpv6 add rule inet t c icmpv6 type echo-request ^^^^^^^^^^^ Since I wouldn't expect an IP packet carrying ICMPv6, or IPv6 packet carrying ICMP, if the link layer is inet, the network layer protocol context can be safely update to 'ip' or 'ip6'. Moreover, nft currently generates a 'meta nfproto ipvX' depedency when using icmp or icmp6 in the inet family, and similar in netdev and bridge families. While at it, a bit of code factorization is introduced.

| | | | | | | | | | Add two tests to make sure that set size checks work fine: 1) Check if set size is indeed working, this is a simple one. 2) Check if set size is correct after ENFILE error, there is bug that adds a new spare slot everytime we hit this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following command: # nft --debug=mnl add rule x y flow table xyz { ip saddr timeout 30s counter } breaks with EINVAL. The following netlink message is causing the problem: ... ---------------- ------------------ | 0000000044 | | message length | | 02572 | R--- | | type | flags | | 0000000004 | | sequence number| | 0000000000 | | port ID | ---------------- ------------------ | 02 00 00 00 | | extra header | |00008|--|00002| |len |flags| type| | 78 79 7a 00 | | data | x y z |00008|--|00004| |len |flags| type| | 00 00 00 01 | | data | |00006|--|00001| |len |flags| type| | 78 00 00 00 | | data | x ---------------- ------------------ ... This is incorrect since this describes no elements at all, so it is useless. Add upfront check before iterating over the list of set elements so the netlink message is not placed in the batch. This patch also adds a set so flow tables are minimally covered. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the 'fib' expression which can be used to obtain the output interface from the route table based on either source or destination address of a packet. This can be used to e.g. add reverse path filtering: # drop if not coming from the same interface packet # arrived on # nft add rule x prerouting fib saddr . iif oif eq 0 drop # accept only if from eth0 # nft add rule x prerouting fib saddr . iif oif eq "eth0" accept # accept if from any valid interface # nft add rule x prerouting fib saddr oif accept Querying of address type is also supported. This can be used to e.g. only accept packets to addresses configured in the same interface: # fib daddr . iif type local Its also possible to use mark and verdict map, e.g.: # nft add rule x prerouting meta mark set 0xdead fib daddr . mark type vmap { blackhole : drop, prohibit : drop, unicast : accept } Signed-off-by: Florian Westphal <fw@strlen.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce rt expression for routing related data with support for nexthop (i.e. the directly connected IP address that an outgoing packet is sent to), which can be used either for matching or accounting, eg. # nft add rule filter postrouting \ ip daddr 192.168.1.0/24 rt nexthop != 192.168.0.1 drop This will drop any traffic to 192.168.1.0/24 that is not routed via 192.168.0.1. # nft add rule filter postrouting \ flow table acct { rt nexthop timeout 600s counter } # nft add rule ip6 filter postrouting \ flow table acct { rt nexthop timeout 600s counter } These rules count outgoing traffic per nexthop. Note that the timeout releases an entry if no traffic is seen for this nexthop within 10 minutes. # nft add rule inet filter postrouting \ ether type ip \ flow table acct { rt nexthop timeout 600s counter } # nft add rule inet filter postrouting \ ether type ip6 \ flow table acct { rt nexthop timeout 600s counter } Same as above, but via the inet family, where the ether type must be specified explicitly. "rt classid" is also implemented identical to "meta rtclassid", since it is more logical to have this match in the routing expression going forward. Signed-off-by: Anders K.
