Package: ebtables Version: 2.0.10.4-3 Severity: normal Dear Maintainer,
Armhf version ebtables binary cannot communicate with arm64 kernel. It can be reproduced on qemu. The detailed versions of components are listed below: ebtables: 2.0.10.4-3(armhf) kernel: Linux 4.9.0-3-arm64 #1 SMP Debian 4.9.30-2 (2017-06-12) The error occurs when inserting rules into kernel or listing exist rules when the ruleset is not empty. For example, ebtables -A FORWARD -i eth0 -j DROP [ 591.994988] kernel msg: ebtables bug: please report to author: Standard target size too big Unable to update the kernel. Two possible causes: 1. Multiple ebtables programs were executing simultaneously. The ebtables userspace tool doesn't by default support multiple ebtables programs running concurrently. The ebtables option —concurrent or a tool like flock can be used to support concurrent scripts that update the ebtables kernel tables. 2. The kernel doesn't support a certain ebtables extension, consider recompiling your kernel or insmod the extension. Kind regards, Miao Wang
