hggdhthe problem is release times. Anyway, every LTS now supports newer kernels05:08
hggdhso whatever is the kernel for 18.10, it will be available on 18.04, 16.04, etc05:09
hggdhaand then... there is this ASLR thingy cooking05:10
hans_hggdh, what about ASLR?09:08
=== TJ_Remix is now known as TJ-
hggdhhans_: https://www.theregister.co.uk/2018/01/02/intel_cpu_design_flaw/14:17
hans_hggdh, think i will be ok if i create a file called /etc/sysctl.d/01-disable-aslr.conf  containing kernel.randomize_va_space = 0   ?14:19
hans_>however we're looking at a ballpark figure of five to 30 per cent slow down14:19
hans_holy shit14:20
hans_PostgreSQL slowdowns between 17-23% on "SELECT 1" x.x14:21
hggdhhans_: not a good idea do disable ASLR. Unless you have a guaranteed secure system (hint: theoretical construct), you want ASLR14:27
hggdhand, right now, as the article above points out, this is pretty much speculation, since the issue(s) is(are) still under wrap14:28
hggdhso, if it pans out as being commented by El Reg and others, we will have to soldier up and swallow the performance loss14:29
hggdhyup. It will b fun to watch. I already bought popcorn and soda14:32
TJ-hggdh: I saw what you did there! 'speculation' about the speculative execution crossing privilege boundary bug :)14:33
hggdhthis, as far as I understand, has been going for a while. It probably reached critical mass the last few days, so we get to know about something coming up14:35
=== Night__ is now known as |Night|
TJ-The patches have been in-development since October at least in public, but there appears to be an embargo being lifted on Friday, which suggests an exploit for this is known14:36
TJ-The original patches from the research team were published in April/May14:36
lotuspsychjeanyone needs bugs tested, let me know im on bionic18:47
flocculantlotuspsychje: I'll bear that in mind - though you'd need an Xubuntu iso :p18:52
lotuspsychjeah im on ubuntu-desktop flocculant 18:53
* flocculant tries to 'run' Xubuntu's qa but very few people say anything18:53
flocculantlotuspsychje: I guessed ;) though I do update the ubuntu iso daily when I run my script - hence being able to check things you ask about18:53
lotuspsychjeflocculant: you can always pass me active !bugs ill have a look if you need18:54
flocculantthat's awesome :)18:54
lotuspsychjehere's my list18:54
lotuspsychjeflocculant: https://bugs.launchpad.net/~lotuspsychje/+reportedbugs18:54
lotuspsychjeedited all ubuntu versions in title18:55
flocculantif there's any wayland/xorg things - that completely confuses me :)18:55
lotuspsychjeflocculant: i presume xfce runs fine already?18:56
flocculantand any amd specific - nvida/nouveau here18:56
lotuspsychjeflocculant: believe it or not, the only flawless system im testing smooth on wayland is on nvidia laptop lol18:56
lotuspsychjeall other lag somehow on xorg or wayland18:57
flocculantyea xfce is fine afaik - I'm also using the Xubuntu Team 'official' ppa's and some from git unreleased18:57
flocculantbut any bugs I might mention will be vanilla iso ones18:57
flocculantI could install a ubuntu instance - but it'll be rarely used and I would need to update etc before checking18:58
lotuspsychjeflocculant: that would be very usefull if you test wayland also18:58
flocculantbut if that's the price of being able to ask someone to check xubuntu things - I'll pay it :D18:58
lotuspsychjeflocculant: as that will be our future ubuntu-desktop method18:59
flocculantack - won't be setting it up today - but I will by weekend18:59
flocculant(mostly I get the iso to find if an issue I see is a generic *flavour one)19:00
lotuspsychjeflocculant: no sweat tyt mate19:00
flocculantbookmarked your list for when I do it :)19:00
lotuspsychjeflocculant: i think Bashing-om also runs xubuntu bionic?19:02
flocculantpossibly - know him from old :)19:03
flocculantlike for years :p19:03
Bashing-omlotuspsychje: Not yet .. still on xenial - pending what I am going to do about my hard drives .19:04
lotuspsychjesolid volunteers here19:04
flocculantBashing-om: :)19:04
flocculantand hi19:04
flocculantdidn't see you hiding19:04
lotuspsychjeBashing-om: we discussed, as flocculant testing xubuntu flavor for bionic19:04
Bashing-omflocculant: Good to read you .. long time without :)19:04
flocculantalways about - just a different name ;)19:04
Bashing-omI have some indications that the bios bug in 17.10 carries over to bionic . be careful .19:05
flocculantnot affected 19:06
flocculantor if I am - I've not noticed19:06
lotuspsychje!info linux-image-generic bionic19:06
ubottulinux-image-generic (source: linux-meta): Generic Linux kernel image. In component main, is optional. Version (bionic), package size 2 kB, installed size 14 kB19:06
flocculantprobably because I always grab -proposed kernel when they show up19:06
lotuspsychjeBashing-om: i was wondering, what artful upgrade to bionic would influence that bug??19:06
flocculantI thought the current kernel was ok - you could upgrae to there - but not totally sure as (see above)19:07
lotuspsychjei think users start solving the bug with .19 and higher19:08
lotuspsychje14.9 14.10 sorry19:09
Bashing-omI tend to trust ventrical:  https://ubuntuforums.org/showthread.php?t=2380665&page=3 .19:11
lotuspsychjeBashing-om: weird the bug url doesnt mention bionic?19:14
Bashing-omlotuspsychje: Just to keep an open mind about it .19:15
lotuspsychjeBashing-om: tomorrow alpha1, so lets hope they fix that right away19:17
Bashing-omlotuspsychje: maybe now UEFI will get defined by the manufacturers ?19:17
lotuspsychjeim always a paranoia thinker myself..intel did this on purpose to block ubuntu instead of MS? lol19:17
flocculantlotuspsychje: no alpha's r beta1 for Ubuntu19:18
flocculantthey ignore till Final Beta19:18
lotuspsychjeapple upload new Ios to make worst batterys...19:18
flocculant(Xubuntu ignores till Beta 1 too)19:18
lotuspsychjeflocculant: kk19:18
flocculantlotuspsychje: only flavours who're interested do alphas/betas19:19
lotuspsychjeflocculant: lets c what kind of updates will come tru tomorrow..19:19
lotuspsychjehad a few this morning19:19
* flocculant grabbed some a short while ago - all 'generic'19:19
flocculantthe xfce/xubuntu stuff usually shows up at ~6am for me19:20
flocculantthen I go to work :D19:20
