Package: linux-image-6.12.69+deb13-amd64 Severity: normal Tags: ipv6 Dear Maintainer,
I've updated to the latest version of the 6.12. branch from 6.12.63 to 6.12.69. I have a ip6gre tunnel secured by ipsec. after the update to that version no packet is received anymore on the gre device and the error counter counts up for every inbound gre packet. The information that the error counter counts seems to confirm that the kernel finds the right gre device the packet should be delivered to. I recompiled the kernel reverting https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/net/ipv6/ip6_tunnel.c?id=81c734dae203757fb3c9eee6f9896386940776bd and now the custom dpkg-buildpackage (now obviosly -unsigned) works again. Looking at the code I don't see why it would fail, especially since kernel 6.19 from ubuntu seems to work (I did not check if 6.19 includes this, if it does not that the mentioned commit above is the real regression) Thanks -- System Information: Debian Release: 13.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 6.12.69+deb13-amd64 (SMP w/4 CPU threads; PREEMPT) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages linux-image-6.12.69+deb13-amd64 depends on: pn initramfs-tools | linux-initramfs-tool <none> ii kmod 34.2-2 pn linux-base <none> Versions of packages linux-image-6.12.69+deb13-amd64 recommends: pn apparmor <none> Versions of packages linux-image-6.12.69+deb13-amd64 suggests: pn debian-kernel-handbook <none> pn firmware-linux-free <none> pn grub-pc | grub-efi-amd64 | extlinux <none> pn linux-doc-6.12 <none>
