Package: network-manager Version: 1.30.6-1+deb11u1 Severity: important Tags: ipv6
Dear Maintainer, Using Debian Stable on a laptop and on the WiFi router. WiFi router has network-manager connection sharing enabled to a Linux bridge, to which an ethernet interface and the WiFi AP-mode interface is bound. Laptop sporadially loses the IPv6 default route, which can be re-gained by disconnecting and reconnecting to the WiFi, or alternatively manually adding it back. When the default route is removed, existing IPv6 connections (e.g. mosh, ssh etc) hang. This happens repeatedly, but sporadically. Nothing appears in the logs on the laptop when the default route is deleted - it seems Network Manager just decides to delete it. The IPv4 default route remains, along with all the other interface configuration. It is only the IPv6 default route that seems to vanish. -- System Information: Debian Release: 11.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-18-amd64 (SMP w/4 CPU threads) Kernel taint flags: TAINT_WARN Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages network-manager depends on: ii adduser 3.118 ii dbus 1.12.24-0+deb11u1 ii libaudit1 1:3.0-2 ii libbluetooth3 5.55-3.1 ii libc6 2.31-13+deb11u4 ii libcurl3-gnutls 7.74.0-1.3+deb11u3 ii libglib2.0-0 2.66.8-1 ii libgnutls30 3.7.1-5+deb11u2 ii libjansson4 2.13.1-1.1 ii libmm-glib0 1.14.12-0.2 ii libndp0 1.6-1+b1 ii libnewt0.52 0.52.21-4+b3 ii libnm0 1.30.6-1+deb11u1 ii libpsl5 0.21.0-1.2 ii libreadline8 8.1-1 ii libselinux1 3.1-3 ii libsystemd0 247.3-7+deb11u1 ii libteamdctl0 1.31-1 ii libudev1 247.3-7+deb11u1 ii libuuid1 2.36.1-8+deb11u1 ii policykit-1 0.105-31+deb11u1 ii udev 247.3-7+deb11u1 ii wpasupplicant 2:2.9.0-21 Versions of packages network-manager recommends: ii dnsmasq-base [dnsmasq-base] 2.85-1 ii iptables 1.8.7-1 ii libpam-systemd 247.3-7+deb11u1 ii modemmanager 1.14.12-0.2 ii ppp 2.4.9-1+1 ii wireless-regdb 2022.04.08-2~deb11u1 Versions of packages network-manager suggests: ii isc-dhcp-client 4.4.1-2.3+deb11u1 pn libteam-utils <none> -- no debconf information
