commit 6abb6a299971df82f2eb481e7336c3c0122d37f9 Author: Yawning Angel yawning@schwanenlied.me Date: Thu Dec 29 01:30:00 2016 +0000
Bug 21093: Unbreak the Debian build, by kludging gosecco.
gosecco has code to load seccomp filters with the Linux 3.17 system call, but certain copies of the debian headers pre-date the introduction of this.
Disabling all the calls is harmless since all gosecco is used for is parsing and copiling rules, and the disabled routines are for using the library to install the filter (which we offload to bubblewrap).
Note: Why yes, this is a repeat of 3b568bda74. --- .../src/github.com/twtiger/gosecco/native/calls.go | 41 ++++++++++++++++++++++ 1 file changed, 41 insertions(+)
