[Touch-packages] [Bug 1846232] Re: networkd pads interface MTU by 4 bytes for vlan even when told not to
Hello Dan, or anyone else affected, Accepted systemd into eoan-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/242-7ubuntu3.3 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-eoan to verification-done-eoan. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-eoan. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: systemd (Ubuntu Eoan) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-eoan -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1846232 Title: networkd pads interface MTU by 4 bytes for vlan even when told not to Status in curtin: Invalid Status in systemd: Fix Released Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Eoan: Fix Committed Bug description: [impact] vlan interface has wrong mtu, which may cause lost packets due to incorrect mtu [test case] configure a system using the netplan cfg similar to comment 2. alternately, networkd config can be used, similar to: ubuntu@lp1846232-e:/run/systemd/network$ grep . * 10-netplan-ens3.2667.netdev:[NetDev] 10-netplan-ens3.2667.netdev:Name=ens3.2667 10-netplan-ens3.2667.netdev:MTUBytes=1500 10-netplan-ens3.2667.netdev:Kind=vlan 10-netplan-ens3.2667.netdev:[VLAN] 10-netplan-ens3.2667.netdev:Id=2667 10-netplan-ens3.2667.network:[Match] 10-netplan-ens3.2667.network:Name=ens3.2667 10-netplan-ens3.2667.network:[Network] 10-netplan-ens3.2667.network:LinkLocalAddressing=ipv6 10-netplan-ens3.2667.network:Address=1.2.3.4/32 10-netplan-ens3.2667.network:ConfigureWithoutCarrier=yes 10-netplan-ens3.link:[Match] 10-netplan-ens3.link:OriginalName=ens3 10-netplan-ens3.link:[Link] 10-netplan-ens3.link:WakeOnLan=off 10-netplan-ens3.link:MTUBytes=1500 10-netplan-ens3.network:[Match] 10-netplan-ens3.network:Name=ens3 10-netplan-ens3.network:[Network] 10-netplan-ens3.network:LinkLocalAddressing=ipv6 10-netplan-ens3.network:VLAN=ens3.2667 The reboot and check the mtus: ubuntu@lp1846232-e:~$ ip l show ens3 2: ens3: mtu 1504 qdisc fq_codel state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:12:99:1b brd ff:ff:ff:ff:ff:ff ubuntu@lp1846232-e:~$ ip l show ens3.2667 3: ens3.2667@ens3: mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:12:99:1b brd ff:ff:ff:ff:ff:ff The base interface should have a mtu of only 1500.

[Touch-packages] [Bug 1846232] Re: networkd pads interface MTU by 4 bytes for vlan even when told not to
I believe this is due to https://github.com/systemd/systemd/commit/4b151b71320bbee1549afcbad5554a40d90d63b4 and probably is https://github.com/systemd/systemd/issues/12552 fixed by https://github.com/systemd/systemd/pull/12574/commits which prevents the automatic mtu bump when MTUBytes is specified but i'm still uncertain about upstream's link_get_requested_mtu_by_stacked_netdevs() function, that bumps MTU automatically; I might be misunderstanding it, but I don't think it is needed or even correct - but I need to look more closely at it and haven't had time. ** Bug watch added: github.com/systemd/systemd/issues #12552 https://github.com/systemd/systemd/issues/12552 ** Also affects: systemd via https://github.com/systemd/systemd/issues/12552 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1846232 Title: networkd pads interface MTU by 4 bytes for vlan even when told not to Status in curtin: Invalid Status in systemd: Unknown Status in systemd package in Ubuntu: New Bug description: From https://jenkins.ubuntu.com/server/job/curtin-vmtest-devel- amd64/916/console: == FAIL: test_ip_output (vmtests.test_network_vlan.EoanTestNetworkVlan) -- Traceback (most recent call last): File "/var/lib/jenkins/servers/server/workspace/curtin-vmtest-devel-amd64/curtin-916/tests/vmtests/test_network.py", line 311, in test_ip_output routes) File "/var/lib/jenkins/servers/server/workspace/curtin-vmtest-devel-amd64/curtin-916/tests/vmtests/test_network.py", line 337, in check_interface int(ipcfg[key])) AssertionError: 1500 != 1504 >> begin captured stdout << - parsed ip_a dict: interface0: broadcast: 10.245.175.255 group: default inet4: - address: 10.245.168.16 prefixlen: '21' scope: global valid_lft: forever inet6: - address: fec0::d6be:d9ff:fea8:4913 prefixlen: '64' scope: site valid_lft: 86256sec - address: fe80::d6be:d9ff:fea8:4913 prefixlen: '64' scope: link valid_lft: forever interface: interface0 loopback: false lower_up: false mac_address: d4:be:d9:a8:49:13 mtu: '1500' multicast: false qdisc: fq_codel qlen: '1000' running: false state: UP up: false interface1: broadcast: 10.245.188.255 group: default inet4: - address: 10.245.188.2 prefixlen: '24' scope: global valid_lft: forever inet6: - address: fec0::d6be:d9ff:fea8:4915 prefixlen: '64' scope: site valid_lft: 86256sec - address: fe80::d6be:d9ff:fea8:4915 prefixlen: '64' scope: link valid_lft: forever interface: interface1 loopback: false lower_up: false mac_address: d4:be:d9:a8:49:15 mtu: '1504' multicast: false qdisc: fq_codel qlen: '1000' running: false state: UP up: false interface1.2667: broadcast: 10.245.184.255 group: default inet4: - address: 10.245.184.2 prefixlen: '24' scope: global valid_lft: forever inet6: - address: fe80::d6be:d9ff:fea8:4915 prefixlen: '64' scope: link valid_lft: forever interface: interface1.2667 loopback: false lower_up: false mac_address: d4:be:d9:a8:49:15 mtu: '1500' multicast: false qdisc: noqueue qlen: '1000' running: false state: UP up: false vlan_link: interface1 interface1.2668: broadcast: 10.245.185.255 group: default inet4: - address: 10.245.185.1 prefixlen: '24' scope: global valid_lft: forever inet6: - address: fe80::d6be:d9ff:fea8:4915 prefixlen: '64' scope: link valid_lft: forever interface: interface1.2668 loopback: false lower_up: false mac_address: d4:be:d9:a8:49:15 mtu: '1500' multicast: false qdisc: noqueue qlen: '1000' running: false state: UP up: false vlan_link: interface1 interface1.2669: broadcast: 10.245.186.255 group: default inet4: - address: 10.245.186.1 prefixlen: '24' scope: global valid_lft: forever inet6: - address: fe80::d6be:d9ff:fea8:4915 prefixlen: '64' scope: link valid_lft: forever interface: interface1.2669 loopback: false lower_u
