Title: Automatic ipv4 not assigned to bond interface is manual ipv6 is assigned to it Status in Ubuntu on IBM z Systems: Fix Released Status in network-manager package in Ubuntu: Fix Released Status in network-manager source package in Bionic: Fix Committed Bug description: [Impact] In case creating bond interface, IPv4 address is not automatically assigned when IPv6 has manual setting. [Test Case] 1. create 18.04.4 instance, network-manager version is 1.10.6-2ubuntu.1.2 as original description. 2. ipv6 manual, ipv4 auto ################################## sudo nmcli con add type bond con-name bond0 ifname bond0 mode active-backup; sudo nmcli con mod bond0 bond.options "downdelay=0, fail_over_mac=none, miimon=100, mode=active-backup,num_grat_arp=0, primary_reselect=always, updelay=0"; sudo nmcli con mod bond0 ipv6.method manual ipv6.addresses fe81::ff:fe97:a27f/64; sudo nmcli con mod bond0 ipv4.method auto; sudo nmcli con add type bond-slave ifname ens34 master bond0; sudo nmcli con add type bond-slave ifname ens35 master bond0; sudo nmcli con mod bond0 +bond.options mii=100 sleep 5 sudo nmcli con up bond-slave-ens34 sudo nmcli con up bond-slave-ens35 sudo nmcli con up bond0; sleep 5; sudo nmcli c s bond0 ################################## 3. ipv6 auto, ipv4 auto ################################## sudo nmcli con add type bond con-name bond0 ifname bond0 mode active-backup; sudo nmcli con mod bond0 bond.options "downdelay=0, fail_over_mac=none, miimon=100, mode=active-backup,num_grat_arp=0, primary_reselect=always, updelay=0"; sudo nmcli con mod bond0 ipv6.method auto; sudo nmcli con mod bond0 ipv4.method auto; sudo nmcli con add type bond-slave ifname ens34 master bond0; sudo nmcli con add type bond-slave ifname ens35 master bond0; sudo nmcli con mod bond0 +bond.options mii=100 sleep 5 sudo nmcli con up bond-slave-ens34 sudo nmcli con up bond-slave-ens35 sudo nmcli con up bond0; sleep 5 sudo nmcli c s bond0 ################################## when run #3, it is working, but with #2, it is not working. [Potential Regression] Actually nothing special. fix just remove if statement. but it needs Network Manager restarted. [Other informations] After upstream fix, it is working fine with #2 and #3 above. * Upstream bug and fix: https://bugzilla.redhat.com/show_bug.cgi?id=1575944 https://gitlab.freedesktop.org/NetworkManager/NetworkManager/commit/f03ae35 * Only affecting Bionic: $ git describe --contains f03ae35 1.10.8~2 $ rmadison network-manager ==> network-manager | 1.10.6-2ubuntu1.2 | bionic-updates network-manager | 1.20.4-2ubuntu2.2 | eoan-updates network-manager | 1.22.4-1ubuntu2 | focal [Original description] ---Problem Description--- Bond interface with automatic ipv4 mode and manual ipv6 mode fails to get automatic ipv4 assigned from dhcp server. ---uname output--- Linux NetworkTest 4.15.0-33-generic #36-Ubuntu SMP Wed Aug 15 13:42:17 UTC 2018 s390x s390x s390x GNU/Linux Machine Type = s390x ---Debugger--- A debugger is not configured ---Steps to Reproduce--- When user configures ipv4 as automatic and ipv6 as manual for bond interface automatic ipv4 is not getting assigned. Looks like dhcp client request for ipv4 is not done to dhcp server after maunal ipv6 is assigned quickly to bond interface This issue will not happen in below cases: 1)with ipv4 automatic and ipv6 manual configuration for ethernet or vlan interface. 2)with ipv4 automatic and ipv6 automatic configuration for bond interface 3)with ipv4 automatic and ipv6 disabled configuration for bond interface Configuration: Bond interface, ipv4 automatic mode and ipv6 automatic mode root@NetworkTest:/etc/NetworkManager/system-connections# cat test_bond [connection] id=test_bond uuid=63e54542-5135-47ac-a954-b861c3937be2 type=bond interface-name=test_bond permissions= timestamp=1537944121 [ethernet] mac-address-blacklist= [bond] downdelay=0 fail_over_mac=none miimon=100 mode=active-backup num_grat_arp=0 primary_reselect=always updelay=0 [ipv4] dns-search= method=auto [ipv6] addr-gen-mode=stable-privacy dns-search= method=auto From /var/log/syslog, we can see ip got assigned: Sep 26 06:26:26 NetworkTest dhclient[8663]: DHCPDISCOVER on test_bond to 255.255.255.255 port 67 interval 3 (xid=0x5e04bf1e) Sep 26 06:26:26 NetworkTest dhclient[8663]: DHCPREQUEST of 10.2.3.55 on test_bond to 255.255.255.255 port 67 (xid=0x5e04bf1e) Sep 26 06:26:26 NetworkTest dhclient[8663]: DHCPOFFER of 10.2.3.55 from 10.2.3.1 Sep 26 06:26:26 NetworkTest dhclient[8663]: DHCPACK of 10.2.3.55 from 10.2.3.1 root@NetworkTest:/etc/NetworkManager/system-connections# ip a s test_bond 28: test_bond: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 02:00:00:b3:b5:22 brd ff:ff:ff:ff:ff:ff inet 10.2.3.55/24 brd 10.2.3.255 scope global dynamic noprefixroute test_bond valid_lft 353sec preferred_lft 353sec inet6 fe80::ff:feb3:b522/64 scope link valid_lft forever preferred_lft forever +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Bond interface, ipv4 automatic mode and ipv6 manual mode root@NetworkTest:/etc/NetworkManager/system-connections# cat test_bond [connection] id=test_bond uuid=3efb153a-a6e4-48fb-aa04-f0b8cb549bab type=bond interface-name=test_bond permissions= timestamp=1537943300 [ethernet] mac-address-blacklist= [bond] downdelay=0 fail_over_mac=none miimon=100 mode=active-backup num_grat_arp=0 primary_reselect=always updelay=0 [ipv4] dns-search= method=auto [ipv6] addr-gen-mode=stable-privacy address1=fe81::32a5:bc5f:287f:8db8/64 dns-search= method=manual No automatic ip assigned to ipv4 and no requests to dhcp server seen in /var/log/syslog root@NetworkTest:/etc/NetworkManager/system-connections# ip a s test_bond 29: test_bond: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 02:00:00:b3:b5:22 brd ff:ff:ff:ff:ff:ff inet6 fe81::32a5:bc5f:287f:8db8/64 scope link noprefixroute valid_lft forever preferred_lft forever ==> Correct LP-Package need to be assigned...!
