[19:34] <kees> is 16.10 still expected to be a v4.8 kernel?
[19:38] <rtg> kees, yes. whats up with KASLR ? I've got your bug at the top of my list.

[19:39] <kees> rtg: what would you like to know? v4.8 lands fixes to hibernation to support KASLR, so if v4.8 goes into 16.10, that bug can go away. ;)
[19:39] <kees> (that bug has some hilarious new attachments too)
[19:39] <rtg> kees, cool, that is easy then
[19:40] <rtg> I noticed those this morning
[19:43] <kees> okay, so the plan is still for v4.8?
[19:43] <kees> I'd like to recommend two new configs: HARDENED_USERCOPY and RANDOMIZE_MEMORY
[19:44] <kees> well, maybe three. how about SLAB_FREELIST_RANDOM too
[19:44] <rtg> kees, I've got RANDOMIZE_MEMORY=y, but don't see HARDENED_USERCOPY yet.
[19:45] <rtg> debian.master/config/config.common.ubuntu:CONFIG_SLAB_FREELIST_RANDOM=y
[19:46] <kees> and, if you haven't, can you pick up Debian's patch to perf? https://lkml.org/lkml/2016/1/11/587  upstream doesn't like it, but Android and Debian ship with this as perf's attack surface is kind of huge
[19:46] <kees> rtg: HARDENED_USERCOPY and RANDOMIZE_MEMORY got merged in the last week or so when the v4.8 merge window opened.
[19:47] <rtg> kees, ok, my unstable repo is only at 4.8-rc1
[19:47] <kees> gotcha
[19:47] <kees> these should appear when rc2 gets cut
[19:48] <rtg> kees, as for the perf patch, please start a bug and assign me to it so it doesn't get lost.
[19:48] <kees> okay, cool
