* src: add --literal optionPablo Neira Ayuso2018-07-071-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Default not to print the service name as we discussed during the NFWS. # nft list ruleset table ip x { chain y { tcp dport 22 ip saddr 1.1.1.1 } } # nft -l list ruleset table ip x { chain y { tcp dport ssh ip saddr 1.1.1.1 } } # nft -ll list ruleset table ip x { chain y { tcp dport 22 ip saddr 1dot1dot1dot1.cloudflare-dns.com } } Then, -ll displays FQDN. just like the (now deprecated) --ip2name (-N) option.

* libnftables: Simplify nft_run_cmd_from_buffer footprintPhil Sutter2018-06-181-5/+4
| | | | | | | | | | | | | | | | | | | | | | | With libnftables documentation being upstream and one confirmed external user (nftlb), time to break the API! First of all, the command buffer passed to nft_run_cmd_from_buffer may (and should) be const. One should consider it a bug if that function ever changed it's content. On the other hand, there is no point in passing the buffer's length as separate argument: NULL bytes are not expected to occur in the input, so it is safe to rely upon strlen(). Also, the actual parsers don't require a buffer length passed to them, either. The only use-case for it is when reallocating the buffer to append a final newline character, there strlen() is perfectly sufficient.
