            Bug ID: 85485
           Summary: downloading files in a systemd-nspawn container with
                    --network-bridge are sometimes broken
           Product: systemd
           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
          Assignee: systemd-bugs at lists.freedesktop.org
          Reporter: mail at leo-von-klenze.de
        QA Contact: systemd-bugs at lists.freedesktop.org

I've the following setup:

- physical box with two network interfaces, eth0 and eth1. The following
interfaces are created via systemd-networkd on that server:
-- home-br0: bridge interface
-- home: VLAN (id = 10), added to the bridge
-- eth0: configured to use VLAN home
- a router with openwrt that act as dhcp server for the vlan home
- a systemd container running with systemd-nspawn --network-bridge=home-br0

I've the following effect:
1) the interface host0 inside the container gets always a 169.254.* address
after startup as well as an address from the dhcp server. After deleting the
169.254.* address the network went well exectp of
2) downloading files via wget/curl/... result sometimes in broken files if the
file is big enough (> 50MB)

2)
Only some bytes a broken in the downloaded file. I've also watched the traffic
in tcpdump on the router/physical box/container: sometimes the a packet from
the internet contains already the broken bytes but the packet seems not to be
rejected an resend afterwards.

I was not able to reproduce the problem starting the container without
--network-bridge.

OS:
Arch Linux, 3.17.1, systemd-216

Thank you in advance,
   Leo
