* netfilter: nf_tables: enable conntrack if NAT chain is registeredPablo Neira Ayuso2018-03-304-7/+45
| | | | | | | | | | | Register conntrack hooks if the user adds NAT chains. Users get confused with the existing behaviour since they will see no packets hitting this chain until they add the first rule that refers to conntrack. This patch adds new ->init() and ->free() indirections to chain types that can be used by NAT chains to invoke the conntrack dependency. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* netfilter: nf_tables: build-in filter chain typePablo Neira Ayuso2018-03-3017-509/+414Star
| | | | | | | | One module per supported filter chain family type takes too much memory for very little code - too much modularization - place all chain filter definitions in one single file. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* netfilter: ebtables: Add string filterBernie Harris2018-03-301-0/+1
| | | | | | | | | | This patch is part of a proposal to add a string filter to ebtables, which would be similar to the string filter in iptables.

* netfilter: ebtables: Add support for specifying match revisionBernie Harris2018-03-302-21/+42
| | | | | | | | | | | | | | | | Currently ebtables assumes that the revision number of all match modules is 0, which is an issue when trying to use existing xtables matches with ebtables. The solution is to modify ebtables to allow extensions to specify a revision number, similar to iptables. This gets passed down to the kernel, which is then able to find the match module correctly. To main binary backwards compatibility, the size of the ebt_entry structures is not changed, only the size of the name field is decreased by 1 byte to make room for the revision field.

* netfilter: x_tables: ensure last rule in base chain matches underflow/policyFlorian Westphal2018-03-053-3/+48
| | | | | | | | | | | | | | | | | | | | | | Harmless from kernel point of view, but again iptables assumes that this is true when decoding ruleset coming from kernel. If a (syzkaller generated) ruleset doesn't have the underflow/policy stored as the last rule in the base chain, then iptables will abort() because it doesn't find the chain policy. libiptc assumes that the policy is the last rule in the basechain, which is only true for iptables-generated rulesets. Unfortunately this needs code duplication -- the functions need the struct layout of the rule head, but that is different for ip/ip6/arptables. NB: pr_warn could be pr_debug but in case this break rulesets somehow its useful to know why blob was rejected.

* netfilter: unlock xt_table earlier in __do_replaceXin Long2018-03-053-3/+6
| | | | | | | | | | | | | | | | | | | Now it's doing cleanup_entry for oldinfo under the xt_table lock, but it's not really necessary. After the replacement job is done in xt_replace_table, oldinfo is not used elsewhere any more, and it can be freed without xt_table lock safely. The important thing is that rtnl_lock is called in some xt_target destroy, which means rtnl_lock, a big lock is used in xt_table lock, a smaller one. It usually could be the reason why a dead lock may happen. Besides, all xt_target/match checkentry is called out of xt_table lock. It's better also to move all cleanup_entry calling out of xt_table lock, just as do_replace_finish does for ebtables.
