Package: systemd Version: 252.22-1~deb12u1 Severity: normal X-Debbugs-Cc: sven.feyerab...@stuvus.uni-stuttgart.de
Dear Maintainer, we've been using a wireguard setup to connect hosts. After upgrading to Debian 12 (systemd 247 to systemd 252) the default route, which has a PreferredSource set is no longer created. To reproduce the issue, consider the following setup: * Interface 1: physical interface, configured for DHCP, routes are added to table 2: [Match] Name=eno1 [Network] DHCP=ipv4 IPForward=True DNS=XXX.XXX.XXX.XXX KeepConfiguration=dhcp [DHCPv4] UseDNS=False RouteTable=2 * Interface 2: the wireguard interface: [Match] Name=wg_rtr [Address] Address=10.53.16.8/32 Peer=192.168.30.1/32 [Address] Address=fe80::1/64 [Link] MTUBytes=1500 [Route] Destination=0.0.0.0/0 Gateway=192.168.30.1 PreferredSource=10.53.16.8 [RoutingPolicyRule] Priority=1 IncomingInterface=lo IPProtocol=udp DestinationPort=51848 Table=2 With this setup, the default route is not created at all and the default routing table looks like this: $ ip r s 192.168.30.1 dev wg_rtr_nili01 proto kernel scope link src 10.53.16.8 On Debian 11 (systemd 247.3-7+deb11u4) this exact same config produces the correct default route: $ ip r s default via 192.168.30.1 dev wg_rtr proto static src 10.53.16.8 192.168.30.1 dev wg_rtr proto kernel scope link src 10.53.16.8 If I omit the PreferredSource option from the [Route] section, everything works as expected: $ ip r s default via 192.168.30.1 dev wg_rtr proto static 192.168.30.1 dev wg_rtr proto kernel scope link src 10.53.16.8 Kind regards, Sven -- Package-specific info: -- System Information: Debian Release: 12.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 6.1.0-13-amd64 (SMP w/4 CPU threads; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages systemd depends on: ii libacl1 2.3.1-3 ii libaudit1 1:3.0.9-1 ii libblkid1 2.38.1-5+b1 ii libc6 2.36-9+deb12u4 ii libcap2 1:2.66-4 ii libcryptsetup12 2:2.6.1-4~deb12u2 ii libfdisk1 2.38.1-5+b1 ii libgcrypt20 1.10.1-3 ii libkmod2 30+20221128-1 ii liblz4-1 1.9.4-1 ii liblzma5 5.4.1-0.2 ii libmount1 2.38.1-5+b1 ii libp11-kit0 0.24.1-2 ii libseccomp2 2.5.4-1+b3 ii libselinux1 3.4-1+b6 ii libssl3 3.0.11-1~deb12u2 ii libsystemd-shared 252.22-1~deb12u1 ii libsystemd0 252.22-1~deb12u1 ii libzstd1 1.5.4+dfsg2-5 ii mount 2.38.1-5+b1 Versions of packages systemd recommends: ii dbus [default-dbus-system-bus] 1.14.10-1~deb12u1 ii systemd-timesyncd [time-daemon] 252.22-1~deb12u1 Versions of packages systemd suggests: ii libfido2-1 1.12.0-2+b1 pn libqrencode4 <none> pn libtss2-esys-3.0.2-0 <none> pn libtss2-mu0 <none> pn libtss2-rc0 <none> ii policykit-1 122-3 ii polkitd 122-3 pn systemd-boot <none> ii systemd-container 252.22-1~deb12u1 pn systemd-homed <none> ii systemd-resolved 252.22-1~deb12u1 pn systemd-userdbd <none> Versions of packages systemd is related to: ii dbus-user-session 1.14.10-1~deb12u1 pn dracut <none> ii initramfs-tools 0.142 ii libnss-systemd 252.22-1~deb12u1 ii libpam-systemd 252.22-1~deb12u1 ii udev 252.22-1~deb12u1 -- Configuration Files: /etc/systemd/journald.conf changed [not included] -- no debconf information
