Package: network-manager Version: 0.9.4.0-5 Severity: important Tags: patch upstream ipv6
Excuse me for filing this bug so late, I thought there was already one in Debian for this issue. But it seems I was only following the upstream discussion. The Linux kernel adds a route cache entry for every destination the system is trying to reach, to track things like MTU and RTT. You can usually see them using "ip -6 route show cache". When network-manager is in ipv6-mode != ignore, it listens to netlink for routing table changes and wrongly adds a static route for every cached entry that appears. This is reported to slow down systems with many peers (i.e. bittorrent) and has security issues as well, since this would make traffic go ways you don't expect. For example, when you fire up LAN, send a packet to some host and then build a VPN connection with a net including that host, the traffic is still sent unencrypted. It also breaks Chromium in some cases This bug has been reported upstream https://bugzilla.gnome.org/show_bug.cgi?id=671767 and in Ubuntu https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1038541 Both have fixed it. Upstream has commited two patches last night that (apart from some fuzz) apply to the Debian package. I'm just building a test and will attach the patch asap. IME this would be an important fix for Wheezy. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (900, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-3-amd64 (SMP w/2 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages network-manager depends on: ii adduser 3.113+nmu3 ii dbus 1.6.0-1 ii dpkg 1.16.8 ii isc-dhcp-client 4.2.2.dfsg.1-5 ii libc6 2.13-35 ii libdbus-1-3 1.6.0-1 ii libdbus-glib-1-2 0.100-1 ii libgcrypt11 1.5.0-3 ii libglib2.0-0 2.32.3-1 ii libgnutls26 2.12.20-1 ii libgudev-1.0-0 175-7 ii libnl-3-200 3.2.7-4 ii libnl-genl-3-200 3.2.7-4 ii libnl-route-3-200 3.2.7-4 ii libnm-glib4 0.9.4.0-5 ii libnm-util2 0.9.4.0-5 ii libpolkit-gobject-1-0 0.105-1 ii libuuid1 2.20.1-5.1 ii lsb-base 4.1+Debian7 ii udev 175-7 ii wpasupplicant 1.0-2 Versions of packages network-manager recommends: ii crda 1.1.2-1 ii dnsmasq-base 2.62-3 ii iptables 1.4.14-3 ii modemmanager 0.5.2.0-1 ii policykit-1 0.105-1 ii ppp 2.4.5-5.1+b1 Versions of packages network-manager suggests: ii avahi-autoipd 0.6.31-1 -- Configuration Files: /etc/NetworkManager/NetworkManager.conf changed [not included] /etc/init.d/network-manager changed [not included] -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
