(works in 4.19.13) To: linux-netdev@vger.kernel.org Cc: jeffrey.t.kirsher@intel.com, roopa@cumulusnetworks.com, nikolay@cumulusnetworks.com, "linux-kernel@vger.kernel.org" Content-Type: text/plain; charset="UTF-8" Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi, Switching from 4.19.x -> 4.20 resulted in DHCP not working for my VM:s. My firewall (which also runs the dhcpd) runs VM:s and it does this by having physical interfaces attached to bridges - which the VM:s in turn attach to. Since 4.20 the VM:s can't use DHCP, it's odd since the requests are seen - a response is sent but it never enters the interface attached to the bridge. Basically: VM vnet2: -> br0 -> eno2 -> switch -> eno1 (dhcpd) dhcpd eno1 -> siwtch and... gone. Any clues? All the nics are handled by ixgbe
