I was assigned 14.75 hours of work by Freexian's Debian LTS initiative and worked all of these hours.
I prepared a security update for the Linux kernel and issued DLA 849-1. I also continued catching up with the backlog of fixes for the Linux 3.2 longterm stable branch. I released stable update 3.2.87 and started preparing the next stable update.
I was assigned 13 hours of work by Freexian's Debian LTS initiative and carried over 15.25 from January. I worked 19 hours and have returned the remaining 9.25 hours to the general pool.
I prepared a security update for the Linux kernel and issued DLA-833-1. However, I spent most of my time catching up with a backlog of fixes for the Linux 3.2 longterm stable branch. I issued two stable updates (3.2.85, 3.2.86).
I was assigned 12.75 hours of work by Freexian's Debian LTS initiative and carried over 5.5 from December. I worked only 3 hours, so I carry over 15.25 hours - but I will probably give up some of those to the general pool.
I spent some time finishing off the linux security update mentioned in my December entry. I also backported the current version of wireless-regdb - not a security update, but an important one anyway - and issued DLA 785-1.
There are a fair number of outstanding security issues in the Linux kernel for Debian 8 "jessie", but none of them were considered serious enough to issue a security update and DSA. Instead, most of them are being fixed through the point release (8.7) which will be released this weekend. Don't forget that you need to reboot to complete a kernel upgrade.
This update to linux (version 3.16.39-1) also adds the perf security mitigation feature from Grsecurity. You can disable unprivileged use of perf entirely by setting sysctl kernel.perf_event_paranoid=3. (This is the default for Debian "stretch".)
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.
