* libipt_ULOG: fix --ulog-cprangePablo Neira Ayuso2012-05-091-2/+2
| | | | | | | | | | | In 1f2474a libipt_ULOG: use guided option parser. A bug has been accidentally introduced in --ulog-cprange, limiting possible values from 1 to 50. However, that limit should be applied to --ulog-qthreshold. Reported-by: Gaurav Sinha <vgsinha@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* libiptc: fix retry path in TC_INITMiguel GAIO2012-04-191-1/+1
| | | | | | | | | | | There is an issue on TC_INIT retry path: In error case, TC_FREE is called and close sockfd. The retry does not reopen then always fail. The proposing patch reopens sockfd in retry patch. Signed-off-by: Miguel GAIO <miguel.gaio@efixo.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* libxt_CT: add --timeout optionPablo Neira Ayuso2012-04-023-12/+139
| | | | | | | | | | | | | | | | | | | | This patch adds the --timeout option to allow to attach timeout policy objects to flows, eg. iptables -I PREROUTING -t raw -s 1.1.1.1 -p tcp \ -j CT --timeout custom-tcp-policy You need the nfct(8) tool which is available at: http://git.netfilter.org/cgi-bin/gitweb.cgi?p=nfct.git To define the cttimeout policies. Example of usage: nfct timeout add custom-tcp-policy inet tcp established 1000 The new nfct tool also requires libnetfilter_cttimeout: http://git.netfilter.org/cgi-bin/gitweb.cgi?p=libnetfilter_cttimeout.git Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* extensions: add nfacct matchPablo Neira Ayuso2012-03-273-0/+136
| | | | | | | | | | | | | | This patch provides the user-space iptables support for the nfacct match. This can be used as it follows: nfacct add http-traffic iptables -I INPUT -p tcp --sport 80 -m nfacct --nfacct-name http-traffic iptables -I OUTPUT -p tcp --dport 80 -m nfacct --nfacct-name http-traffic nfacct get http-traffic See also man nfacct(8) for more information.

* src: mark newly opened fds as FD_CLOEXEC (close on exec)Maciej ┼╗enczykowski2012-03-232-0/+15
| | | | | | | | | | | | | | | | | | By default, Unix-like systems leak file descriptors after fork/exec call. I think this seem to result in SELinux spotting a strange AVC log messages according to what I can find on the web. Fedora 18 iptables source includes this change. Maciej says: "iptables does potentially fork/exec modprobe to load modules. That can cause a selinux 'domain'/'role'/whatever-it-is-called crossing. You can do automated inspection of what gets carried across such privilege changes and any unexpected open file descriptors flag problems, patches like this cut down on the noise."

| | | | | | | | | This reverts commit d65702c5c5bbab0ef12298386fa4098c72584e6c. This is breaking my iptables scripts: iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT iptables: Incompatible with this kernel.

* | extensions: link on libxtables and check symbolsJan Engelhardt2011-12-312-11/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | Have each extension link against libxtables.so; with this, all home symbols are known at link time and we can use ld's --no-undefined to run the check, dropping the homebrew solution. By having libxtables.so required by extensions, package managers' automatic dependency discovery will become effective so that manual dependencies for distros with split extension packages (e.g. OpenWRT) will not be necessary anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | quoting man page: match packets from a connection whose packets/bytes/average packet size is more than FROM and less than TO bytes/packets. if TO is omitted only FROM check is done. But, when TO was omitted, we did treat it like "x:x" which is not the same at all. Before commit 09631dc60ce41bc484a42fcf4d4ddf7036820bd1 (libxt_connbytes: use guided option parser), we failed to parse "--connbytes x" ('Bad range "x"'), but treated "x:" like "x:0xffffffff". Also, restore the "from must be smaller than to" check. Signed-off-by: Florian Westphal <fw@strlen.de>
