However if I boot a new debian testing VM, it seems not to work. Both VMs are downloaded from http://cdimage.debian.org/cdimage/cloud/ What can be the difference here? I'm lost on debugging this.. -- Shengjing Zhu
Bug#969350: linux-image-4.19.0-10-amd64: Kernel regularly crashes - general protection fault in the network stack

Thank you for the hint; indeed it looks the same as #966846. I have tried the kernel you have prepared and I have not experienced any crash in the last 23 hours (it was crashing more often recently). I will keep you informed if a crash is occurring. Antoine signature.asc Description: PGP signature

Just to confirm, does this mean the driver will be available to future versions on Debian (i.e. have the config options set so that the driver is available in Debian Images)? If so, what versions of Debian will this affect? (I'm guessing the ones starting with linux 5.8?) Thanks. David

Note that
5fd99b5d9950 ("net: cdc_ncm: Fix build error")
should be included in this series for completeness.
It won't make any difference with the default Debian configuration,
where cdc_ether always is enabled, but it was an unfortunate glitch on
my side.

Bug#969365: USB-C dock lacks multicast Ethernet functionality (so IPv6 is broken)
Source: linux Version: 4.19.118-2 Severity: important Tags: ipv6 upstream fixed-upstream IPv6 connectivity (and other network protocols relying on multicast) are broken when using a Dell D6000 USB-C dock. Quoting Miguel Rodríguez that filed the equivalent bug in ubuntu: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1779173: "Dell D6000 exposes a CDC_NCM device for Ethernet traffic. However, multicast Ethernet traffic is not processed making IPv6 not functional. Other services, like mDNS used for LAN service discovery are also hindered. The actual reason is that CDC_NCM driver was not processing requests to filter (admit) multicast traffic. I provide two patches to the linux kernel that admit all Ethernet multicast traffic whenever a multicast group is being joined. The solution is not optimal, as it makes the system receive more traffic than that strictly needed, but otherwise this only happens when the computer is connected to a dock and thus is running on AC power. I believe it is not worth the hassle to join only the requested groups. This is the same that is done in the CDN_ETHER driver." The patches proposed by Miguel Rodríguez have been merged upstream, and are part of 5.9-rc1 now.
