“After years of being outside of the mainline, the AppArmor
security system is now finally part of the main Linux kernel.“Linux founder Linus Torvalds formally released the 2.6.36
kernel this week nearly three months after the release of the
2.6.35 kernel.“AppArmor has been in use by Linux distributions since at least
2006 when Novell first open sourced the code as a rival option to
SELinux which has been championed by Red Hat. Ubuntu picked up
AppArmor in 2007 with the 7.10 Gutsy Gibbon release.“Over the years, Novell had tried to get AppArmor into the
mainline Linux kernel, though in the end it was Ubuntu that led the
successful charge to that got AppArmor into the 2.6.36 kernel.“Canonical is committed to AppArmor’s development and to that
end in order to do it properly it needed to go upstream,” Pete
Graner, Manager of the Ubuntu Kernel at Canonical told
InternetNews.com.”
