* Solves Bug 1462 - `nft -j list set` does not show countersGopal Yadav13 days1-1/+7
| | | | | | | | | Element counters reside in 'stmt' field as counter statement. Append them to 'elem' object as additional 'counter' property, generated by counter_stmt_json(). Signed-off-by: Gopal Yadav <gopunop@gmail.com> Signed-off-by: Phil Sutter <phil@nwl.cc>

* json: Expect refcount increment by json_array_extend()Phil Sutter2020-07-291-2/+4
| | | | | | | | | | | This function is apparently not "joining" two arrays but rather copying all items from the second array to the first, leaving the original reference in place. Therefore it naturally increments refcounts, which means if used to join two arrays caller must explicitly decrement the second array's refcount.

* src: store expr, not dtype to track data in setsFlorian Westphal2019-12-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will be needed once we add support for the 'typeof' keyword to handle maps that could e.g. store 'ct helper' "type" values. Instead of: set foo { type ipv4_addr . mark; this would allow set foo { typeof(ip saddr) . typeof(ct mark); (exact syntax TBD). This would be needed to allow sets that store variable-sized data types (string, integer and the like) that can't be used at at the moment. Adding special data types for everything is problematic due to the large amount of different types needed. For anonymous sets, e.g. "string" can be used because the needed size can be inferred from the statement, e.g. 'osf name { "Windows", "Linux }', but in case of named sets that won't work because 'type string' lacks the context needed to derive the size information. With 'typeof(osf name)' the context is there, but at the moment it won't help because the expression is discarded instantly and only the data type is retained.

* src: add and use `set_is_meter` helperJeremy Sowden2019-11-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sets constructed for meters are flagged as anonymous and dynamic. However, in some places there are only checks that they are dynamic, which can lead to normal sets being classified as meters. For example: # nft add table t # nft add set t s { type ipv4_addr; size 256; flags dynamic,timeout; } # nft add chain t c # nft add rule t c tcp dport 80 meter m size 128 { ip saddr limit rate 10/second } # nft list meters table ip t { set s { type ipv4_addr size 256 flags dynamic,timeout } meter m { type ipv4_addr size 128 flags dynamic } } # nft list meter t m table ip t { meter m { type ipv4_addr size 128 flags dynamic } } # nft list meter t s Error: No such file or directory list meter t s ^ Add a new helper `set_is_meter` and use it wherever there are checks for meters.

| | | | | | | | | | | | | | | | | | | | | | | 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 is a partial revert of b0f6a45b25dd1 ("src: add --literal option") which was added during the development cycle before 0.9.1 is released. After looking at patch: https://patchwork.ozlabs.org/patch/969864/ that allows to print priority, uid, gid and protocols as numerics, I decided to revisit this to provide individual options to turn on literal printing. What I'm proposing is to provide a good default for everyone, and provide options to turn on literal/numeric printing. This patch adds nft_ctx_output_{set,get}_flags() and define two flags to enable reverse DNS lookups and to print ports as service names.

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.
