* extensions: libxt_NFLOG: display nflog-size even if it is zeroLiping Zhang2016-07-191-1/+1
| | | | | | | | | | | | | | The following iptables rules have the different semantics: # iptables -A INPUT -j NFLOG # iptables -A INPUT -j NFLOG --nflog-size 0 But they are all displayed as "-A INPUT -j NFLOG", so if the user input the following commands, the original semantics will be broken. # iptables-save | iptables-restore Signed-off-by: Liping Zhang <liping.zhang@spreadtrum.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* extensions: libxt_connlabel: fix crash when connlabel.conf is emptyLiping Zhang2016-07-161-3/+10
| | | | | | | | | | | | | | When connlabel.conf is empty, nfct_labelmap_new will return NULL and set errno to 0. So we will miss to check this situation, and cause NULL deference in nfct_labelmap_get_bit. Input the following commands will reproduce this crash: # echo > /etc/xtables/connlabel.conf # iptables -A INPUT -m connlabel --label abc Segmentation fault (core dumped) Signed-off-by: Liping Zhang <liping.zhang@spreadtrum.com> Signed-off-by: Florian Westphal <fw@strlen.de>
* xtables-translate: fix multiple spaces issuePablo M. Bermudo Garay2016-07-0932-146/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a multiple spaces issue. The problem arises when a rule set loaded through iptables-compat-restore is listed in nft. Before this commit, two spaces were printed after every match translation: $ sudo iptables-save *filter :INPUT ACCEPT [0:0] -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m multiport --dports 80:85 -m ttl --ttl-gt 5 -j ACCEPT COMMIT $ sudo iptables-compat-restore iptables-save $ sudo nft list ruleset table ip filter { chain INPUT { type filter hook input priority 0; policy accept; ct state related,established counter packets 0 bytes 0 accept ^^ ip protocol tcp tcp dport 80-85 ip ttl gt 5 counter packets 0 bytes 0 accept ^^ ^^ } } Signed-off-by: Pablo M.

* extensions: added AR substitutionJordan Yelloz2016-07-011-0/+1
| | | | | | | | | | | | This is to ensure that the correct AR is run in cross-compile jobs. Often a cross-compile build will succeed without this change but it fails on my Gentoo Linux system when I have binutils installed with the "multitarget" USE flag. This change substitues AR with the autotools-supplied AR for the extensions subdirectory. Signed-off-by: Jordan Yelloz <jordan@yelloz.me> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* extensions: libxt_NFLOG: nflog-range does not truncate packetsVishwanath Pai2016-07-013-3/+31
| | | | | | | | | | | | | | | | | | | | The option --nflog-range has never worked, but we cannot just fix this because users might be using this feature option and their behavior would change. Instead add a new option --nflog-size. This option works the same way nflog-range should have, and both of them are mutually exclusive. When someone uses --nflog-range we print a warning message informing them that this feature has no effect. To indicate the kernel that the user has set --nflog-size we have to pass a new flag XT_NFLOG_F_COPY_LEN. Also updated the man page to reflect the new option and added tests to extensions/libxt_NFLOG.t Reported-by: Joe Dollard <jdollard@akamai.com> Reviewed-by: Josh Hunt <johunt@akamai.com> Signed-off-by: Vishwanath Pai <vpai@akamai.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
