=== Elimin8r is now known as Elimin8er === lotuspsychje_ is now known as lotuspsychje [05:08] the problem is release times. Anyway, every LTS now supports newer kernels [05:09] so whatever is the kernel for 18.10, it will be available on 18.04, 16.04, etc [05:10] aand then... there is this ASLR thingy cooking [09:08] hggdh, what about ASLR? === TJ_Remix is now known as TJ- [14:17] hans_: https://www.theregister.co.uk/2018/01/02/intel_cpu_design_flaw/ [14:19] 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] >however we're looking at a ballpark figure of five to 30 per cent slow down [14:20] holy shit [14:21] PostgreSQL slowdowns between 17-23% on "SELECT 1" x.x [14:27] hans_: not a good idea do disable ASLR. Unless you have a guaranteed secure system (hint: theoretical construct), you want ASLR [14:28] and, right now, as the article above points out, this is pretty much speculation, since the issue(s) is(are) still under wrap [14:29] so, if it pans out as being commented by El Reg and others, we will have to soldier up and swallow the performance loss [14:31] hggggu [14:31] dam [14:32] yup. It will b fun to watch. I already bought popcorn and soda [14:33] hggdh: I saw what you did there! 'speculation' about the speculative execution crossing privilege boundary bug :) [14:33] :-) [14:35] this, 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 up === Night__ is now known as |Night| [14:36] 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 known [14:36] The original patches from the research team were published in April/May [18:47] anyone needs bugs tested, let me know im on bionic [18:52] lotuspsychje: I'll bear that in mind - though you'd need an Xubuntu iso :p [18:53] ah im on ubuntu-desktop flocculant [18:53] * flocculant tries to 'run' Xubuntu's qa but very few people say anything [18:53] lotuspsychje: I guessed ;) though I do update the ubuntu iso daily when I run my script - hence being able to check things you ask about [18:54] flocculant: you can always pass me active !bugs ill have a look if you need [18:54] that's awesome :) [18:54] here's my list [18:54] flocculant: https://bugs.launchpad.net/~lotuspsychje/+reportedbugs [18:55] edited all ubuntu versions in title [18:55] if there's any wayland/xorg things - that completely confuses me :) [18:56] flocculant: i presume xfce runs fine already? [18:56] and any amd specific - nvida/nouveau here [18:56] flocculant: believe it or not, the only flawless system im testing smooth on wayland is on nvidia laptop lol [18:57] all other lag somehow on xorg or wayland [18:57] yea xfce is fine afaik - I'm also using the Xubuntu Team 'official' ppa's and some from git unreleased [18:57] cool [18:57] but any bugs I might mention will be vanilla iso ones [18:58] kk [18:58] I could install a ubuntu instance - but it'll be rarely used and I would need to update etc before checking [18:58] flocculant: that would be very usefull if you test wayland also [18:58] but if that's the price of being able to ask someone to check xubuntu things - I'll pay it :D [18:59] flocculant: as that will be our future ubuntu-desktop method [18:59] ack - won't be setting it up today - but I will by weekend [19:00] (mostly I get the iso to find if an issue I see is a generic *flavour one) [19:00] flocculant: no sweat tyt mate [19:00] bookmarked your list for when I do it :) [19:02] flocculant: i think Bashing-om also runs xubuntu bionic? [19:03] possibly - know him from old :) [19:03] like for years :p [19:03] hehe [19:04] lotuspsychje: Not yet .. still on xenial - pending what I am going to do about my hard drives . [19:04] solid volunteers here [19:04] Bashing-om: :) [19:04] and hi [19:04] didn't see you hiding [19:04] Bashing-om: we discussed, as flocculant testing xubuntu flavor for bionic [19:04] flocculant: Good to read you .. long time without :) [19:04] always about - just a different name ;) [19:05] I have some indications that the bios bug in 17.10 carries over to bionic . be careful . [19:06] not affected [19:06] or if I am - I've not noticed [19:06] !info linux-image-generic bionic [19:06] linux-image-generic (source: linux-meta): Generic Linux kernel image. In component main, is optional. Version 4.13.0.17.18 (bionic), package size 2 kB, installed size 14 kB [19:06] probably because I always grab -proposed kernel when they show up [19:06] Bashing-om: i was wondering, what artful upgrade to bionic would influence that bug?? [19:07] I thought the current kernel was ok - you could upgrae to there - but not totally sure as (see above) [19:08] i think users start solving the bug with .19 and higher [19:09] 14.9 14.10 sorry [19:11] I tend to trust ventrical: https://ubuntuforums.org/showthread.php?t=2380665&page=3 . [19:14] Bashing-om: weird the bug url doesnt mention bionic? [19:15] lotuspsychje: Just to keep an open mind about it . [19:16] yeah [19:17] Bashing-om: tomorrow alpha1, so lets hope they fix that right away [19:17] lotuspsychje: maybe now UEFI will get defined by the manufacturers ? [19:17] im always a paranoia thinker myself..intel did this on purpose to block ubuntu instead of MS? lol [19:18] lotuspsychje: no alpha's r beta1 for Ubuntu [19:18] they ignore till Final Beta [19:18] apple upload new Ios to make worst batterys... [19:18] (Xubuntu ignores till Beta 1 too) [19:18] flocculant: kk [19:19] lotuspsychje: only flavours who're interested do alphas/betas [19:19] flocculant: lets c what kind of updates will come tru tomorrow.. [19:19] had a few this morning [19:19] * flocculant grabbed some a short while ago - all 'generic' [19:19] :p [19:20] the xfce/xubuntu stuff usually shows up at ~6am for me [19:20] then I go to work :D [19:21] :p
