Description Bertrand Jacquin 2015-10-31 14:02:24 UTC 
When USE=seccomp is enabled, net-misc/lldpd-0.7.11-r3 fail to start:

# /usr/sbin/lldpd -d -x -cc -S foo.bar -I eth0 -m 192.0.2.42                                                                 
2015-10-31T06:47:22 [WARN/control] unable to connect to socket /run/lldpd.socket: Connection refused
2015-10-31T06:47:22 [WARN/lldpctl] unknown command from argument 1: `#`

2015-10-31T06:47:22 [WARN/seccomp] invalid syscall attempted: fcntl(72)


Reproducible: Always
Comment 1 Patrick McLean gentoo-dev 2015-11-11 22:05:16 UTC 
Could you please test with lldpd-0.7.13?
If that works we will stabilize it, and remove the broken version.

lldpd-0.9-seccomp-fcntl.patch

Does this patch fix the problem (you should be able to drop it in /etc/portage/patches/net-misc/lldpd and rebuild the package)
