[systemd-devel] systemd-networkd: broken network in container

[arnaud gaboury]

Since a few days, after some upgrades, I don't have anymore network in my
container. Network is OK on my host

-------------------------------
Host: Archlinux -
% systemctl --version
systemd 231
+PAM -AUDIT -SELINUX -IMA -APPARMOR +SMACK -SYSVINIT +UTMP +LIBCRYPTSETUP
+GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN

Container: Fedora 24 -
% systemctl --version
systemd 229
+PAM +AUDIT +SELINUX +IMA -APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP
+GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN
--------------------------------------

Looking at journalctl on host, I found these errors:

Nov 22 13:47:54 hortensia systemd-networkd[2777]: br0: Could not append

Nov 22 13:47:54 hortensia systemd-networkd[2777]: br0: Failed to assign

Googling these above lines brings me to this issue: #3876[0]

Any progress on it? I can't see where these errors come from. Any hint or
dirty hack ?
