Package: systemd Version: 247.3-3 Severity: normal Tags: ipv6 upstream patch
Dear Maintainer, After configuring IPv6 Proxy NDP addresses on a link, and not receiving any errors, the addresses disappeared from the link during the system startup process. Restarting systemd-networkd restored the addresses to the link, and the system operated as expected. After extensive debugging, it was determined that in some cases during system startup, a NIC will temporarily lose its 'carrier' (link) status, and when this happens any previously-configured Proxy NDP addresses on the link are removed by the kernel networking stack. systemd-networkd was aware of this state change, but did not re-add the Proxy NDP addresses to the link. This was reported and confirmed upstream here: https://github.com/systemd/systemd/issues/18378 A patch was provided to upstream, and merged here: https://github.com/systemd/systemd/pull/18494 The patch was also merged to the upstream 'stable' branch here: https://github.com/systemd/systemd-stable/issues/89 -- Package-specific info: -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-3-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages systemd depends on: ii adduser 3.118 ii libacl1 2.2.53-10 ii libapparmor1 2.13.6-9 ii libaudit1 1:3.0-2 ii libblkid1 2.36.1-7 ii libc6 2.31-9 ii libcap2 1:2.44-1 ii libcrypt1 1:4.4.17-1 ii libcryptsetup12 2:2.3.4-2 ii libgcrypt20 1.8.7-3 ii libgnutls30 3.7.0-7 ii libgpg-error0 1.38-2 ii libip4tc2 1.8.7-1 ii libkmod2 28-1 ii liblz4-1 1.9.3-1 ii liblzma5 5.2.5-1.0 ii libmount1 2.36.1-7 ii libpam0g 1.4.0-6 ii libseccomp2 2.5.1-1 ii libselinux1 3.1-3 ii libsystemd0 247.3-3 ii libzstd1 1.4.8+dfsg-2.1 ii mount 2.36.1-7 ii systemd-timesyncd [time-daemon] 247.3-3 ii util-linux 2.36.1-7 Versions of packages systemd recommends: ii dbus 1.12.20-2 Versions of packages systemd suggests: ii policykit-1 0.105-30 ii systemd-container 247.3-3 Versions of packages systemd is related to: pn dracut <none> ii initramfs-tools 0.139 pn libnss-systemd <none> ii libpam-systemd 247.3-3 ii udev 247.3-3 -- Configuration Files: /etc/systemd/resolved.conf changed [not included] -- no debconf information
