| hggdh | the problem is release times. Anyway, every LTS now supports newer kernels | 05:08 |
|---|---|---|
| hggdh | so whatever is the kernel for 18.10, it will be available on 18.04, 16.04, etc | 05:09 |
| hggdh | aand then... there is this ASLR thingy cooking | 05:10 |
| hans_ | hggdh, what about ASLR? | 09:08 |

| hggdh | hans_: 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 down | 14:19 |
| hans_ | holy shit | 14:20 |
| hans_ | PostgreSQL slowdowns between 17-23% on "SELECT 1" x.x | 14:21 |
| hggdh | hans_: not a good idea do disable ASLR. Unless you have a guaranteed secure system (hint: theoretical construct), you want ASLR | 14:27 |
| hggdh | and, right now, as the article above points out, this is pretty much speculation, since the issue(s) is(are) still under wrap | 14:28 |
| hggdh | so, if it pans out as being commented by El Reg and others, we will have to soldier up and swallow the performance loss | 14:29 |
| hans_ | hggggu | 14:31 |
| hans_ | dam | 14:31 |
| hggdh | yup. It will b fun to watch. I already bought popcorn and soda | 14:32 |
| TJ- | hggdh: I saw what you did there! 'speculation' about the speculative execution crossing privilege boundary bug :) | 14:33 |
| hggdh | :-) | 14:33 |
| hggdh | 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 | 14:35 |

| 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 known | 14:36 |
| TJ- | The original patches from the research team were published in April/May | 14:36 |
| lotuspsychje | anyone needs bugs tested, let me know im on bionic | 18:47 |
| flocculant | lotuspsychje: I'll bear that in mind - though you'd need an Xubuntu iso :p | 18:52 |
| lotuspsychje | ah im on ubuntu-desktop flocculant | 18:53 |
| * flocculant tries to 'run' Xubuntu's qa but very few people say anything | 18:53 | |
| flocculant | 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 | 18:53 |
| lotuspsychje | flocculant: you can always pass me active !bugs ill have a look if you need | 18:54 |
| flocculant | that's awesome :) | 18:54 |
| lotuspsychje | here's my list | 18:54 |
| lotuspsychje | flocculant: https://bugs.launchpad.net/~lotuspsychje/+reportedbugs | 18:54 |
| lotuspsychje | edited all ubuntu versions in title | 18:55 |
| flocculant | if there's any wayland/xorg things - that completely confuses me :) | 18:55 |
| lotuspsychje | flocculant: i presume xfce runs fine already? | 18:56 |
| flocculant | and any amd specific - nvida/nouveau here | 18:56 |
| lotuspsychje | flocculant: believe it or not, the only flawless system im testing smooth on wayland is on nvidia laptop lol | 18:56 |
| lotuspsychje | all other lag somehow on xorg or wayland | 18:57 |
| flocculant | yea xfce is fine afaik - I'm also using the Xubuntu Team 'official' ppa's and some from git unreleased | 18:57 |
| lotuspsychje | cool | 18:57 |
| flocculant | but any bugs I might mention will be vanilla iso ones | 18:57 |
| lotuspsychje | kk | 18:58 |
| flocculant | I could install a ubuntu instance - but it'll be rarely used and I would need to update etc before checking | 18:58 |
| lotuspsychje | flocculant: that would be very usefull if you test wayland also | 18:58 |
| flocculant | but if that's the price of being able to ask someone to check xubuntu things - I'll pay it :D | 18:58 |
| lotuspsychje | flocculant: as that will be our future ubuntu-desktop method | 18:59 |
| flocculant | ack - won't be setting it up today - but I will by weekend | 18:59 |
| flocculant | (mostly I get the iso to find if an issue I see is a generic *flavour one) | 19:00 |
| lotuspsychje | flocculant: no sweat tyt mate | 19:00 |
| flocculant | bookmarked your list for when I do it :) | 19:00 |
| lotuspsychje | flocculant: i think Bashing-om also runs xubuntu bionic? | 19:02 |
| flocculant | possibly - know him from old :) | 19:03 |
| flocculant | like for years :p | 19:03 |
| lotuspsychje | hehe | 19:03 |
| Bashing-om | lotuspsychje: Not yet .. still on xenial - pending what I am going to do about my hard drives . | 19:04 |
| lotuspsychje | solid volunteers here | 19:04 |
| flocculant | Bashing-om: :) | 19:04 |
| flocculant | and hi | 19:04 |
| flocculant | didn't see you hiding | 19:04 |
| lotuspsychje | Bashing-om: we discussed, as flocculant testing xubuntu flavor for bionic | 19:04 |
| Bashing-om | flocculant: Good to read you .. long time without :) | 19:04 |
| flocculant | always about - just a different name ;) | 19:04 |
| Bashing-om | I have some indications that the bios bug in 17.10 carries over to bionic . be careful . | 19:05 |
| flocculant | not affected | 19:06 |
| flocculant | or if I am - I've not noticed | 19:06 |
| lotuspsychje | !info linux-image-generic bionic | 19:06 |
| ubottu | 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 |
| flocculant | probably because I always grab -proposed kernel when they show up | 19:06 |
| lotuspsychje | Bashing-om: i was wondering, what artful upgrade to bionic would influence that bug?? | 19:06 |
| flocculant | I thought the current kernel was ok - you could upgrae to there - but not totally sure as (see above) | 19:07 |
| lotuspsychje | i think users start solving the bug with .19 and higher | 19:08 |
| lotuspsychje | 14.9 14.10 sorry | 19:09 |
| Bashing-om | I tend to trust ventrical: https://ubuntuforums.org/showthread.php?t=2380665&page=3 . | 19:11 |
| lotuspsychje | Bashing-om: weird the bug url doesnt mention bionic? | 19:14 |
| Bashing-om | lotuspsychje: Just to keep an open mind about it . | 19:15 |
| lotuspsychje | yeah | 19:16 |
| lotuspsychje | Bashing-om: tomorrow alpha1, so lets hope they fix that right away | 19:17 |
| Bashing-om | lotuspsychje: maybe now UEFI will get defined by the manufacturers ? | 19:17 |
| lotuspsychje | im always a paranoia thinker myself..intel did this on purpose to block ubuntu instead of MS? lol | 19:17 |
| flocculant | lotuspsychje: no alpha's r beta1 for Ubuntu | 19:18 |
| flocculant | they ignore till Final Beta | 19:18 |
| lotuspsychje | apple upload new Ios to make worst batterys... | 19:18 |
| flocculant | (Xubuntu ignores till Beta 1 too) | 19:18 |
| lotuspsychje | flocculant: kk | 19:18 |
| flocculant | lotuspsychje: only flavours who're interested do alphas/betas | 19:19 |
| lotuspsychje | flocculant: lets c what kind of updates will come tru tomorrow.. | 19:19 |
| lotuspsychje | had a few this morning | 19:19 |
| * flocculant grabbed some a short while ago - all 'generic' | 19:19 | |
| lotuspsychje | :p | 19:19 |
| flocculant | the xfce/xubuntu stuff usually shows up at ~6am for me | 19:20 |
| flocculant | then I go to work :D | 19:20 |
| lotuspsychje | :p | 19:21 |
