* extensions: nfacct: Fix alignment mismatch in xt_nfacct_match_infoJuliana Rodrigueiro2019-08-201-0/+5
| | | | | | | | | | | | | | | | When running a 64-bit kernel with a 32-bit iptables binary, the size of the xt_nfacct_match_info struct diverges. kernel: sizeof(struct xt_nfacct_match_info) : 40 iptables: sizeof(struct xt_nfacct_match_info)) : 36 This patch is the userspace fix of the memory misalignment. It introduces a v1 ABI with the correct alignment and stays compatible with unfixed revision 0 kernels.

* include: extend the headers conflict workaround to in6.hBaruch Siach2018-12-031-1/+1
| | | | | | | | | | | | | Commit 8d9d7e4b9ef ("include: fix build with kernel headers before 4.2") introduced a kernel/user headers conflict workaround that allows build of iptables with kernel headers older than 4.2. This minor extension allows build with kernel headers older than 3.12, which is the version that introduced explicit IP headers synchronization.

* include: fix build with kernel headers before 4.2Baruch Siach2018-11-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 672accf1530 (include: update kernel netfilter header files) updated linux/netfilter.h and brought with it the update from kernel commit a263653ed798 (netfilter: don't pull include/linux/netfilter.h from netns headers). This triggers conflict of headers that is fixed in kernel commit 279c6c7fa64f (api: fix compatibility of linux/in.h with netinet/in.h) included in kernel version 4.2. For earlier kernel headers we need a workaround that prevents the headers conflict. Fixes the following build failure: In file included from .../sysroot/usr/include/netinet/ip.h:25:0, from ../include/libiptc/ipt_kernel_headers.h:8, from ../include/libiptc/libiptc.h:6, from libip4tc.c:29: .../sysroot/usr/include/linux/in.h:26:3: error: redeclaration of enumerator ‘IPPROTO_IP’ IPPROTO_IP = 0, /* Dummy protocol for TCP */ ^ .../sysroot/usr/include/netinet/in.h:33:5: note: previous definition of ‘IPPROTO_IP’ was here IPPROTO_IP = 0, /* Dummy protocol for TCP. */ ^~~~~~~~~~ Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Florian Westphal <fw@strlen.de>

| | | | | | | This reverts commit 0a8f2bcadff157489a737f8cc8846adcb750b91f. Google folks are reporting some issues with 32-bits arch, let's revert this until we have a new version for this.
* extensions: libxt_quota: Allow setting the remaining quotaChenbo Feng2018-10-091-3/+5
| | | | | | | | | | | | | | | | The current xt_quota module cannot track the current remaining quota of a specific rule. Everytime an unrelated rule is updated in the same iptables table, the quota will be reset. This is not a very useful function for iptables that get changed at run time. This patch fixes the above problem by adding a new field in the struct that records the current remaining quota. Fixed a print out bug in verbose print out wrt. inversion.

This allows existing logic operators (and, or and xor) and mask to co-operate with new bitshift operations. The intention is to provide uses with more fexible uses of skb->mark and ct->mark.

* extensions: libipt_DNAT: support shifted portmap rangesThierry Du Tre2018-04-291-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a proposal patch for iptables DNAT extension to support shifted portmap ranges. It is related to the kernel patch proposed in earlier message '[PATCH v5] netfilter : add NAT support for shifted portmap ranges'. A new struct nf_nat_range2 was added as extension for existing struct nf_nat_range and is used by new revisions (2) for the DNAT target. Current DNAT revisions for Ipv4 (rev 0) and IPv6 (rev 1) are kept so functionality with older kernels is not impacted. The syntax for shifted portmaps uses an extra value in '--to-destination' for setting the base port which determines the offset in the redirect port range for incoming connections. i.e. : iptables -t nat -A zone_wan_prerouting -p tcp -m tcp --dport 5000:5100 -j DNAT --to-destination '192.168.1.2:2000-2100/5000' The base port value is totally optional, so current behavior is not impacted in any way. The use of slash '/' as separator is an arbitrary choice, all other suggestions are valid of course (original proposal used semicolon but this was not practical for commandline use) Another approach using an additional option seems also possible (i.e. '--base-port 5000'). However, that would mean more parsing logic with extra lines of code and thus increased risk for regression.

* netfilter: xt_hashlimit: add rate match modeVishwanath Pai2017-09-081-6/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new feature to hashlimit that allows matching on the current packet/byte rate without rate limiting. This can be enabled with a new flag --hashlimit-rate-match. The match returns true if the current rate of packets is above/below the user specified value. The main difference between the existing algorithm and the new one is that the existing algorithm rate-limits the flow whereas the new algorithm does not. Instead it *classifies* the flow based on whether it is above or below a certain rate. I will demonstrate this with an example below. Let us assume this rule: iptables -A INPUT -m hashlimit --hashlimit-above 10/s -j new_chain If the packet rate is 15/s, the existing algorithm would ACCEPT 10 packets every second and send 5 packets to "new_chain". But with the new algorithm, as long as the rate of 15/s is sustained, all packets will continue to match and every packet is sent to new_chain. This new functionality will let us classify different flows based on their current rate, so that further decisions can be made on them based on what the current rate is. This is how the new algorithm works: We divide time into intervals of 1 (sec/min/hour) as specified by the user. We keep track of the number of packets/bytes processed in the current interval. After each interval we reset the counter to 0. When we receive a packet for match, we look at the packet rate during the current interval and the previous interval to make a decision: if [ prev_rate < user and cur_rate < user ] return Below else return Above Where cur_rate is the number of packets/bytes seen in the current interval, prev is the number of packets/bytes seen in the previous interval and 'user' is the rate specified by the user. We also provide flexibility to the user for choosing the time interval using the option --hashilmit-interval. For example the user can keep a low rate like x/hour but still keep the interval as small as 1 second. To preserve backwards compatibility we have to add this feature in a new revision, so I've created revision 3 for hashlimit. The two new options we add are: --hashlimit-rate-match --hashlimit-rate-interval I have updated the help text to add these new options. Also added a few tests for the new options.

* extensions: libxt_NFLOG: nflog-range does not truncate packetsVishwanath Pai2016-07-011-1/+5
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | xt_socket is useful for matching sockets with IP_TRANSPARENT and taking some action on the matching packets. However, it lacks the ability to match only a small subset of transparent sockets. Suppose there are 2 applications, each with its own set of transparent sockets. The first application wants all matching packets dropped, while the second application wants them forwarded somewhere else. Add the ability to retore the skb->mark from the sk_mark. The mark is only restored if a matching socket is found and the transparent / nowildcard conditions are satisfied. Now the 2 hypothetical applications can differentiate their sockets based on a mark value set with SO_MARK. iptables -t mangle -I PREROUTING -m socket --transparent \ --restore-skmark -j action iptables -t mangle -A action -m mark --mark 10 -j action2 iptables -t mangle -A action -m mark --mark 11 -j action3 Signed-off-by: Harout Hedeshian <harouth@codeaurora.org> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
