Subject: [ptxdist] systemd: seccomp
Date: Sun, 29 Nov 2015 16:21:32 +0100	[thread overview]
Message-ID: <20151129152132.GA975@archie.tuxnet.lan> (raw)

Hi,

I noticed that the systemd rule in ptxdist explicitly disables seccomp
support. Would be great to have support for SystemCallFilter in service
files.

I therefore added libseccomp and modified the systemd rule to enable
seccomp (optionally via a menu entry).
I use the current git master Linux kernel with CONFIG_SECCOMP enabled.

Even though systemctl --version shows +SECCOMP, the SystemCallFilter
statement does not have any effect.
For testing, I only allowed one syscall for a program which needs much
more, but it did still run normally as if no SystemCallFilter had been
set at all.

Platform used:
- ARM (i.MX6Q) with ptxdist: SystemCallFilter had no effect
- x86_64 (Intel i7 6700K) with ArchLinux: Working perfectly

Can you reproduce this and do you have any idea why this isn't working?

Thanks,
Clemens
