* extensions: libxt_limit: fix a wrong translation to nft ruleLiping Zhang2016-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The default burst value is 5 in iptables limit extension while it is 0 in nft limit expression, if the burst value is default, it will not be displayed when we dump the rules. But when we do translation from iptables rules to nft rules, we should keep the limit burst value unchanged, even if it is not displayed in iptables rules. And now, if the limit-burst value in the iptables rule is 5 or 0, they are all translated to nft rule without burst, this is wrong: $ sudo iptables-translate -A INPUT -m limit --limit 10/s --limit-burst 5 nft add rule ip filter INPUT limit rate 10/second counter $ sudo iptables-translate -A INPUT -m limit --limit 10/s --limit-burst 0 nft add rule ip filter INPUT limit rate 10/second burst 0 packets counter Apply this patch, translation will become: $ sudo iptables-translate -A INPUT -m limit --limit 10/s --limit-burst 5 nft add rule ip filter INPUT limit rate 10/second burst 5 packets counter $ sudo iptables-translate -A INPUT -m limit --limit 10/s --limit-burst 0 nft add rule ip filter INPUT limit rate 10/second counter Fixes: a8dfbe3a3acb ("extensions: libxt_limit: Add translation to nft") Cc: Shivani Bhardwaj <shivanib134@gmail.com> Signed-off-by: Liping Zhang <liping.zhang@spreadtrum.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* extensions: libxt_NFQUEUE: Fix bug with order of fanout and bypassShivani Bhardwaj2016-04-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFQUEUE had a bug with the ordering of fanout and bypass options which was arising due to same and odd values for flags and bypass when used together. Because of this, during bitwise ANDing of flags and NFQ_FLAG_CPU_FANOUT, the value always evaluated to false (since NFQ_FLAG_CPU_FANOUT=0x02) and led to skipping of fanout option whenever it was used before bypass because then flags would be 1. Before this patch, $ sudo iptables -A FORWARD -j NFQUEUE -p TCP --sport 80 --queue-balance 0:3 --queue-cpu-fanout --queue-bypass Chain FORWARD (policy ACCEPT) target prot opt source destination NFQUEUE tcp -- anywhere anywhere tcp spt:http NFQUEUE balance 0:3 bypass After this patch, Chain FORWARD (policy ACCEPT) target prot opt source destination NFQUEUE tcp -- anywhere anywhere tcp spt:http NFQUEUE balance 0:3 bypass cpu-fanout Closes bugzilla entry: http://bugzilla.netfilter.org/show_bug.cgi?id=939 Suggested-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Shivani Bhardwaj <shivanib134@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
