Subject: Re: bpfilter causes a leftover kernel process
Date: Mon, 27 Aug 2018 18:31:22 +0200	[thread overview]
Message-ID: <20180827183122.0b4ac65e@jjacky.com> (raw)
In-Reply-To: <20180826180816.04ef7d16@jjacky.com>


Small addentum: Of course I failed to realize this bpfilter helper is
also mentioned in the kernel log:

kern.info: [    8.997711] bpfilter: Loaded bpfilter_umh pid 920


It also seems to be absolutely required when CONFIG_BPFILTER is
enabled, that is I tried blacklisting the module bpfilter, but then
other things (e.g. iptables-restore) just fail to work.

So the process is required, never ends and prevents umouting the
rootfs on shutdown. Unless I'm missing something, there's definitely a
bug there?

Thanks,
