Last year, Bootlin engineer Thomas Petazzoni worked on adding support for two security features in OpenWrt: dm-verity and SELinux.
It turns out that the SELinux work we did was recently picked up by other OpenWrt contributors, and was finally merged upstream. LWN has a nice article about this work: https://lwn.net/Articles/832876/. (Note: article only available to subscribers for one week)
See also our blog post at https://bootlin.com/blog/security-contributions-to-openwrt-dm-verity-and-selinux/ for more details about what we proposed.
