Package: network-manager Version: 1.2.2-1 Severity: normal It is, apparently, not possible to specify the layer 2 MAC address which a virtual bridge interface will use. It appears to randomly re-use a MAC address of one of it's bridged ports (slaves).
I don't think wishlist is an appropriate severity for this bug. This is fundamentally broken with how layer 2 bridging should work. The bridge address should not change based upon the availability (up/down status) of a single port. If a switch from any vendor (Netgear, Cisco, Juniper) did this, it would be broken. It would probably be best for a semi-random address to be generated, stored in configuration, and applied to the interface. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.5.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages network-manager depends on: ii adduser 3.114 ii dbus 1.10.8-1 ii init-system-helpers 1.33 ii isc-dhcp-client 4.3.4-1 ii libaudit1 1:2.5.2-1 ii libbluetooth3 5.36-1+b1 ii libc6 2.22-7 ii libglib2.0-0 2.48.1-1 ii libgnutls30 3.4.11-4 ii libgudev-1.0-0 230-3 ii libmm-glib0 1.4.14-1 ii libndp0 1.6-1 ii libnewt0.52 0.52.18-3 ii libnl-3-200 3.2.27-1 ii libnm0 1.2.2-1 ii libpam-systemd 229-6 ii libpolkit-agent-1-0 0.105-15 ii libpolkit-gobject-1-0 0.105-15 ii libreadline6 6.3-8+b4 ii libselinux1 2.5-3 ii libsoup2.4-1 2.54.1-1 ii libsystemd0 229-6 ii libteamdctl0 1.24-1 ii libuuid1 2.28-5 ii lsb-base 9.20160110 ii policykit-1 0.105-15 ii udev 229-6 ii wpasupplicant 2.3-2.3 Versions of packages network-manager recommends: ii crda 3.13-1+b1 ii dnsmasq-base 2.75-1 ii iptables 1.6.0-2 ii iputils-arping 3:20150815-2 ii modemmanager 1.4.14-1 ii ppp 2.4.7-1+2 Versions of packages network-manager suggests: pn libteam-utils <none> -- Configuration Files: /etc/NetworkManager/NetworkManager.conf changed [not included] -- no debconf information
