* meta: relax restriction on UID/GID parsingPablo Neira Ayuso2013-11-291-20/+34
| | | | | | | | | | nft is currently rejecting unknown UID/GID if they don't exist in the system, relax this as Bjørnar Ness considers this is a valid scenario. Now this only reports an error if you pass an unknown user (expressed as string or if the UID/GID goes above 32 bits).

* meta: fix endianness in UID/GIDPablo Neira Ayuso2013-11-291-2/+2
| | | | | | | | | | | add rule filter output meta skuid vmap { 1000 => accept } list table filter meta skuid map { 3892510720 => accept} ^--------^ this is 1000 in network byte order Reported-by: Bjørnar Ness <bjornar.ness@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* meta: iif/oifname should be host byte orderFlorian Westphal2013-09-231-2/+2
| | | | | | | | | | | | | | | | | | | | src/nft add rule filter output meta oifname eth0 doesn't work on x86. Problem is that nft declares these as BYTEORDER_INVALID, but when converting the string mpz_import_data treats INVALID like BIG_ENDIAN. [ cmp eq reg 1 0x00000000 0x00000000 0x65000000 0x00306874 ] as kernel nft_cmp_eval basically boils down to memcmp(reg, skb->dev->name, sizeof(reg) comparision fails. with patch: [ cmp eq reg 1 0x30687465 0x00000000 0x00000000 0x00000000 ] Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* meta: fix output display of meta lengthPablo Neira Ayuso2013-09-041-1/+1
| | | | | | | | | | | | | nft list table filter Before: meta len 1000 counter packets 0 bytes 0 After: meta length 1000 counter packets 0 bytes 0 Now it doesn't break with nft -f. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* meta: replace rtnl_tc_handle2str and rtnl_tc_str2handlePablo Neira Ayuso2013-06-241-10/+43
| | | | | | | Provide replacements for rtnl_tc_handle2str and rtnl_tc_str2handle, it removes the dependency with libnl-route. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* meta: use if_nametoindex and if_indextonamePablo Neira Ayuso2013-06-241-44/+4
| | | | | | | Instead of having a cache of ifindex based on libnl. Those functions basically use rtnetlink as well to perform the translation. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* meta: accept uid/gid in numericalPablo Neira Ayuso2013-04-201-4/+12
| | | | | | You can use the user/group name or alternatively the uid/gid. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expressions: kill seperate sym_type datatype for symbolsPatrick McHardy2009-04-011-5/+5

* datatype: add/move size and byte order information into data typesPatrick McHardy2009-03-311-2/+12
| | | | | | | | | | Add size and type information to non-basetype types and remove the now redundant information from the symbol tables. This will be used to determine size and byteorder of set members without analyzing the ruleset for incremental update operations. Signed-off-by: Patrick McHardy <kaber@trash.net>
* datatype: maintain table of all datatypes and add registration/lookup functionPatrick McHardy2009-03-311-7/+22
| | | | | | | | | | | Add a table containing all available datatypes and registration/lookup functions. This will be used to associate a stand-alone set in the kernel with the correct type without parsing the entire ruleset. Additionally it would now be possible to remove the global declarations for the core types. Not done yet though. Signed-off-by: Patrick McHardy <kaber@trash.net>
