Yes, that's right. There's always at least one of these typos when I type emails about this :-). It looks like I forgot to rename one of them when I moved the code into a predicate definition. > I also think y...

...e (see bug #440). Now a rule like iptables -A INPUT -p tcp -m multiport --dport 45,47 -m multiport --sport 45:48 actually ends up as: 0 0 tcp -- * * 0.0.0.0/0 0.0.0.0/0 multiport sports multiport sports tcp spts:45:48 As you can see, the matchinfo computed by the last multiport match is 'copied' over the previous ones. IIRC, this is caused by the matchinfo being attached to the match plugin, rather to the instance of a match plugin. -- Configure bugmail: https://bugzilla.netfilter.org/bugzilla/userprefs.cgi?tab=email ------- You a...

There are two problems: 1. padding after union and call to q(), without LTO we can't remove that store. 2. shortcut which I have which ignores all instructions q() . this assume that memset to acpar.match, acpar.matchinfo also useful which is not true. I should be able to improve this case. On Thu, Aug 1, 2019 at 11:29 PM Vitaly Buka <vitalybuka at google.com> wrote: > On a first look case like this should nor be a problem.

...y|major |normal Component|netfilter hooks |ip_tables (kernel) ------- Additional Comments From laforge@netfilter.org 2003-05-31 23:21 ------- Yes, this is a known issue. The reason is that the author of ipt_limit.c stores a pointer (master) inside the matchinfo structure. That pointer is 64bit in the kernel and 32bit in userspace, this is why the structure sizes differ and you receive an invalid argument error. This is not an excuse, I'm just trying to explain what's going on - maybe somebody else wants to pick this up and fix it. ------- You...

...31 23:25 ------- I can confirm this bug. neither libipt_limit.c nor ipt_limit.c contain any handling of inversion. Together with Bug #94, I think it's time to rewrite parts of the limit match in order to address those issues. I doubt this will be possible without any changes to the structure matchinfo size :( ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Hi, some minutes ago IPP2P 0.7 has been released. It offers a couple of new features including: -UDP filtering support for some P2P networks -improved SoulSeek filter -Ares/AresLite matching support -debug option to print matchinfo into kernel log Please consult the README and documentation found at http://www.ipp2p.org for information about changes and new features. You can download the source tarball there as well and please give me as much feedback as possible. Kind regards, Eicke -- IPP2P - P2P traffic detection for i...

Hello guys I don''t know if this thing has been posted before (if it was , please forgive me). I have 7 computers at home and I want all of them to have access to the internet. In order to do that , I set up a linux router (2 network cards) as a usual router (eth0 : 82.77.69.75 - internet connection ; eth1 : 192.168.10.1 - local network) . The other computers have ips ranging from
