* src: introduce struct nft_cacheVarsha Rao2017-08-1412-120/+155

* nft.8: Complete short description of arp familyPhil Sutter2017-08-141-1/+1

* nft.8: Describe base chain detailsPhil Sutter2017-08-141-9/+85
| | | | | | | | | | | This mostly covers base chain types, but also tries to clarify meaning of priority values, chain policy and the ominous device parameter. Command synopsis is adjusted as well to point out which parts of a base chain definition are optional and which are not.

* nft.8: Document operations on rulesetPhil Sutter2017-08-141-15/+72
| | | | | | | | | | | | | People new to nftables and yet unaware of 'list ruleset' and 'flush ruleset' commands have a hard time. Therefore put description of those prominently at the top, even before explaining operations on tables and chains. Since 'export ruleset' is closely related, document it here as well and remove it's sparse description from ADDITIONAL COMMANDS section.

* tests: Add a simple test suite for --echo optionPhil Sutter2017-08-142-0/+57
| | | | | | | | The fancy thing about this is that it uses the actual echo output to undo the changes to the rule set. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* Implement --echo optionPhil Sutter2017-08-148-7/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When used with add, insert or replace commands, nft tool will print event notifications just like 'nft monitor' does for the same commands. Apart from seeing what a given command will turn out in the rule set, this allows to reliably retrieve a new rule's assigned handle (if used together with --handle option). Here are some examples of how it works: | # nft --echo --handle add table ip t | add table ip t | | # nft --echo --handle add chain ip t c \ | '{ type filter hook forward priority 0; }' | add chain ip t c { type filter hook forward priority 0; policy accept; } | | # nft --echo --handle add rule ip t c tcp dport '{22, 80}' accept | add rule ip t c tcp dport { ssh, http } accept # handle 2 | | # nft --echo --handle add set ip t ipset '{ type ipv4_addr; \ | elements = { 192.168.0.1, 192.168.0.2 }; }' | add set ip t ipset { type ipv4_addr; } | add element ip t ipset { 192.168.0.1 } | add element ip t ipset { 192.168.0.2 } Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* netlink: Pass nlmsg flags from rule.cPhil Sutter2017-08-143-52/+48

* tests: fix arp chain testFlorian Westphal2017-08-081-3/+2
| | | | | | | | | | The forward chain isn't supported anymore (on kernel side it only worked if bridge netfilter 'call-arptables' sysctl is on), so this test now fails with nf-next kernel. In nftables one can filter/test arp packets in bridge family directly. Signed-off-by: Florian Westphal <fw@strlen.de>

* monitor: Fix printing of set declarationsPhil Sutter2017-07-275-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | The optional attributes 'flags', 'gc-interval' and 'timeout' have to be delimited by stmt_separator (either newline or semicolon), not 'nl' which is set to whitespace by set_print_plain(). In order to restore readability, change stmt_separator to include a single whitespace after the semicolon. Here's monitor output for the following command: | # nft add set ip t testset { type inet_service; \ | timeout 60s; gc-interval 120s; } Before this patch: | add set ip t testset { type inet_service;timeout 1m gc-interval 2m } With this patch applied: | add set ip t testset { type inet_service; timeout 1m; gc-interval 2m; } Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* monitor: Fix printing of range elements in named setsArturo Borrero Gonzalez2017-07-192-0/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If you add set elements to interval sets, the output is wrong. Fix this by caching first element of the range (first event), then wait for the second element of the range (second event) to print them both at the same time. We also avoid printing the first null element required in the RB tree. Before this patch: % nft add element t s {10-20, 30-40} add element ip t s { 0 } add element ip t s { 10 } add element ip t s { ftp } add element ip t s { 30 } add element ip t s { 41 } After this patch: % nft add element t s {10-20, 30-40} add element ip t s { 10-20 } add element ip t s { 30-40 } Signed-off-by: Arturo Borrero Gonzalez <arturo@netfilter.org> Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* src: Allow passing the parent set to set_expr_alloc()Phil Sutter2017-07-176-12/+19
| | | | | | | | | | | | | | | | | Usually one wants to at least initialize set_flags from the parent, so make allocation of a set's set expression more convenient. The idea to do this came when fixing an issue with output formatting of larger anonymous sets in nft monitor: Since netlink_events_cache_addset() didn't initialize set_flags, calculate_delim() didn't detect it's an anonymous set and therefore added newlines to the output.
