* py: Adjust Nftables class to output flags changesPhil Sutter2018-10-311-18/+11
| | | | | | | | | | | | | Introduce setter/getter methods for each introduced output flag. Ignore NFT_CTX_OUTPUT_NUMERIC_ALL for now since it's main purpose is for internal use. Adjust the script in tests/py accordingly: Due to the good defaults, only numeric proto output has to be selected - this is not a must, but allows for the test cases to remain unchanged.

* src: get rid of nft_ctx_output_{get,set}_numeric()Pablo Neira Ayuso2018-10-303-3/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch adds NFT_CTX_OUTPUT_NUMERIC_SYMBOL, which replaces the last client of the numeric level approach. This patch updates `-n' option semantics to display all output numerically. Note that monitor code was still using the -n option to skip printing the process name, this patch updates that path too to print it inconditionally to simplify things. Given the numeric levels have no more clients after this patch, remove that code. Update several tests/shell not to use -nn. This patch adds NFT_CTX_OUTPUT_NUMERIC_ALL which enables all flags to provide a fully numerical output. Acked-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* JSON: Add support for echo optionPhil Sutter2018-10-291-0/+211
| | | | | | | | | | | | | | | | The basic principle is to not return a JSON object freshly created from netlink responses, but just update the existing user-provided one to make sure callers get back exactly what they expect. To achieve that, keep the parsed JSON object around in a global variable ('cur_root') and provide a custom callback to insert handles into it from received netlink messages. The tricky bit here is updating rules since unique identification is problematic. Therefore drop possibly present handles from input and later assume updates are received in order so the first rule not having a handle set is the right one.

* json: Fix osf ttl supportPhil Sutter2018-10-241-3/+32
| | | | | | | | | | | | | | Having to use numerical values for ttl property in JSON is not practical as these values are arbitrary and meaningful only in netfilter. Instead align JSON output/input with standard API, accepting names for TTL matching strategy. Also add missing documentation in libnftables-json man page and fix JSON equivalent in tests/py.

* monitor: Fix printing of ct objectsPhil Sutter2018-10-154-3/+36
| | | | | | | | | | | | | | | Monitor output is supposed to be single lined without tabs, but ct object were printed with newlines and tabs hard-coded. Fixing this wasn't too hard given that there is 'stmt_separator' to also include semi-colons where required if newline was removed. A more obvious mistake was position of object type in monitor output: Like with other object types, it has to occur between command and table spec. As a positive side-effect, this aligns ct objects better with others (see obj_type_name_array for instance).

* parser_bison: Fix for ECN keyword in LHS of relationalPhil Sutter2018-10-044-0/+48
| | | | | | | | | | | | | | | | | | | | Of all possible TCP flags, 'ecn' is special since it is recognized by lex as a keyword (there is a a field in IPv4 and IPv6 headers with the same name). Therefore it is listed in keyword_expr, but that was sufficient for RHS only. The following statement reproduces the issue: | tcp flags & (syn | ecn) == (syn | ecn) The solution is to limit binop expressions to accept an RHS expression on RHS ("real" LHS expressions don't make much sense there anyway), which then allows keyword_expr to occur there. In order to maintain the recursive behaviour if braces are present, allow primary_rhs_expr to consist of a basic_rhs_expr enclosed in braces. This in turn requires for braced RHS part in relational_expr to be dropped, otherwise bison complains about shift/reduce conflict.

Improve this by writing all commands into a temporary file for processing in a single nft call. Reduces run-time to about 4s.

| | | | | | | | | | | | | | | | | | evaluation step currently prohibits tproxy ip to 1.2.3.4 in ip family, and tproxy ip6 to dead::1 in ip6. This seems an arbitrary limitation, just accept this. The current restriction would make json output support harder than needed, as the tproxy expression generated from json path would have to special-case the table its currently in, rather than just using the family attribute in the json output.

| | | | | | | | | | | | | | | | | | | Commit 3e6ab2b335142 added restraints on reject types for bridge and inet families but aparently those were too strict: If a rule in e.g. inet family contained a match which introduced a protocol dependency, icmpx type rejects were disallowed for no obvious reason. Allow icmpx type rejects in inet family regardless of protocol dependency since we either have IPv4 or IPv6 traffic in there and for both icmpx is fine. Merge restraints in bridge family with those for TCP reset since it already does what is needed, namely checking that ether proto is either IPv4 or IPv6.

Basic arithmetic can also be done with them to ease the addition of relatively higher/lower priority chains. Addition and substraction is possible. Values are also printed with their friendly name within the range of <basicprio> +- 10. Also numeric printing is supported in case of -nnn option (numeric == NFT_NUMERIC_ALL) The supported name-value pairs and where they are valid is based on how x_tables use these values when registering their base chains.
