systemd-networkd bridge dhcp - git commit 5ba6e09
OK, this is the last commit that works properly related to DHCP bridging,
commit 3dd215e056ee9ff23175eca66686ff9b7a566dbf
Author: Tom Gundersen <teg>
Date: Sun Mar 23 21:45:46 2014 +0100
sd-rtnl: add sd_rtnl_message_enter_container()
Extend rta_offset_tb into a stack of offset tables, one for each parent of the
current container, and make sd_rtnl_message_{enter,exit}_container() pop/push
to this stack.
Also make sd_rtnl_message_rewind() parse the top-level container, and use this
when reading a message from the socket.
This changes the API by dropping the now redundant sd_rtnl_message_read()
method.
Hm, do you mean that that's the first broken commit? It's a big change, so I can easily believe that I broke something there, but after that I don't see any obvious candidates...
commit 3dd215e056ee9ff23175eca66686ff9b7a566dbf
is OK.
All the above, starting with

systemd-networkd - git 2086120 - bonding & bridge dhcp
This article is quite optimistic, "Round-robin bonding (mode 0) with virtualization breaks networking for guests. Why? How can I work around it?" https://access.redhat.com/site/articles/16039 With the "bridged bonding" the only usable bonding mode[1] for the libvirt domain(guest) is the 'active-backup 1'. /etc/modprobe.d/bonding.conf: options bonding mode=1 # bonding mode of operation: # 0 for balance-rr # 1 for active-backup # 2 for balance-xor # 3 for broadcast # 4 for 802.3ad # 5 for balance-tlb # 6 for balance-alb (charp) /sys/class/net/bond0/bonding/mode & /sys/devices/virtual/net/bond0/bonding/mode: active-backup 1 # brctl show bridge name bridge id STP enabled interfaces bridge0 8000.001234567830 no bond0 # bondctl detail bond0 Bonding Master: bond0 Oper State: up Slaves: enp3s0 enp1s9 Active Slave: enp3s0 Mode: active-backup 1 Monitor: No monitoring enabled [1] http://www.linux-kvm.org/page/HOWTO_BONDING#Modes And that's it.

Hi poma, Thanks a lot for all your testing (sorry that I haven't gotten back to you before, but I read all your posts :) ). From comment #20 it seems that bridging is working for you as expected? If there are other issues may I ask you to open separate reports? Cheers, Tom Created attachment 888713 [details]

There is a 15 second DHCP lag in this bond-bridge scheme.

Do you mean, per each new issue goes a new report, regardless if it is an issue of the same category?

This variable lag emerges is due to the use of debug kernel i.e. 3.15.0-0.rc2.git1.1.fc21.x86_64. However, it is not within nodebug kernel i.e. 3.15.0-0.rc2.git0.1.fc21.x86_64.
