Debian LTS work, December 2016

I was assigned 13.5 hours of work by Freexian's Debian LTS initiative and carried over 2 from November. I worked only 10 hours, so I carry over 5.5 hours.

As for the last few months, I spent all of this time working on the linux (kernel) package. I backported several security fixes and did some testing of the more invasive changes.

I also added the option to mitigate security issues in the performance events (perf) subsystem by disabling use by unprivileged users. This feature comes from Grsecurity and has been included in Debian unstable and Android kernels for a while. However, for Debian 7 LTS it has to be explicitly enabled by setting sysctl kernel.perf_event_paranoid=3.

I uploaded these changes as linux 3.2.84-1 and then (on 1st January) issued DLA 722-1.
