samP | shilpasd: Hi | 04:01 |
samP | Any critical bugs and pathces to discuss? | 04:01 |
tpatil | No | 04:03 |
samP | There are some minor fixes. I will review them. Please revirew them if you have time | 04:04 |
samP | Nothing critical from my side | 04:04 |

*** openstack changes topic to "Train Work Items (Meeting topic: masakari)" | 04:04 | |
samP | #link https://etherpad.openstack.org/p/masakari-train-workitems | 04:05 |
tpatil | Add functional tests for host failure | 04:06 |
samP | tpatil: thanks | 04:06 |
tpatil | shilpasd: Do you have any updates? | 04:06 |
shilpasd | yes | 04:06 |
*** diablo_rojo has joined #openstack-meeting | 04:06 | |
shilpasd | here we are facing one blocker issue | 04:07 |
shilpasd | Created instances are not getting cleared off after delete | 04:07 |
*** imsurit_ofc has joined #openstack-meeting | 04:09 | |
shilpasd | during cleanup | 04:09 |
tpatil | Th problem is: we are forcefully putting down the compute service on the source host, followed by evacuating the instance from source to destination host | 04:09 |
samP | shilpasd: could you plese share more details | 04:09 |
tpatil | after the evacuation is done completely, we are again setting the compute service to up, but the instances are still shown in the virsh list | 04:10 |
tpatil | on the source host | 04:10 |
shilpasd | tpatil: thanks for elaborating | 04:10 |
tpatil | these will be cleanup either by the periodic tasks in 30 mins or when the compute service on the source host is restarted | 04:10 |
tpatil | so to write functional tests for host failure, we need ssh access of the compute hosts | 04:11 |
samP | tpatil: I have the same understaning about cleanup task | 04:11 |
*** macza has joined #openstack-meeting | 04:11 | |
tpatil | Need to collaborate with CI team to see if it can be done | 04:11 |
samP | got it. need to restart the host or compute service by ssh | 04:13 |
tpatil | samP: Yes | 04:14 |
samP | I think rather than ssh to node, it is easy to shutdown the node form ansible, since zuul can access to ansible in the test environment | 04:14 |
samP | However, currently we can not use these ansible in opentack infra | 04:15 |
*** macza has quit IRC | 04:16 | |
samP | tpatil: as you said, better discuss with infra team about this probelm | 04:16 |
tpatil | shilpasd: Since the tests will be running on the controller node, we will need to find out if it's possible to shutdown compute nodes from tests and I think for that we need ssh access | 04:17 |
tpatil | samP: Yes, we will discuss about it with the CI team | 04:17 |
samP | tpatil: Thanks | 04:17 |
shilpasd | tpatil: will check that | 04:17 |
tpatil | 2. Render graph to show process of recovery workflow | 04:18 |
tpatil | slow progress, need to find out what additional information will be required to be stored in the progress details so that it can used to render the graph in masakari-dashboard | 04:18 |
samP | tpatil: got it. thanks | 04:19 |
tpatil | to store additional information in progress details, we need to make changes to the masakari code but there is a blocker issue due to task flow bug | 04:20 |
tpatil | which is now fixed but the newer version is not yet released | 04:20 |
*** yamamoto has joined #openstack-meeting | 04:20 | |
tpatil | shilpasd: Do you have any updates about task flow issue? | 04:20 |

clarkb | #link http://lists.openstack.org/pipermail/openstack-infra/2019-May/006367.html Denver 2019 Summit/Forum/PTG Recap | 19:04 |
clarkb | As mentioned feel free to followup with any questions that might arise out of that or need for clarification | 19:04 |
clarkb | As expected it was an exhausting trip | 19:04 |
clarkb | I think cross project efforts like infra and qa etc suffered under the newer ptg format | 19:05 |
clarkb | (there were far fewer people in our room(s) than in the more siloed efforts) | 19:05 |
clarkb | but it was still fairly productive | 19:05 |
clarkb | #topic Priority Efforts | 19:05 |
*** openstack changes topic to "Priority Efforts (Meeting topic: infra)" | 19:05 | |
clarkb | Lets dive right in to the fun stuff | 19:06 |
clarkb | #topic Update Config Management | 19:06 |
*** openstack changes topic to "Update Config Management (Meeting topic: infra)" | 19:06 | |
clarkb | We are super close to finishing the puppet 4 upgrades. After this meeting I want to approve the zuul puppet-4 upgrade change | 19:06 |
cmurphy | \o/ | 19:06 |
clarkb | then we can rebase the lists.o.o change without needing to rebase the zuul change | 19:06 |
clarkb | and depending on how zuul change goes can likely get lists.o.o upgrade in today as well | 19:07 |
fungi | sounds good to me | 19:07 |
clarkb | ianw do you want to talk about the ansibling of mirrors and how that will enable us to do tls which should improve docker now or when we get to the official spot for it on the agenda? | 19:07 |
fungi | i'll be around to help fix if it goes sideways | 19:08 |
clarkb | (I think that effort is fairly tightly cuopled to the config management updates at this point as we are looking at converting to ansible for those nodes and improving docker test job success rates) | 19:08 |
ianw | i don't mind :) | 19:08 |
clarkb | lets talk about that now then as I think it is useful to have in this context | 19:09 |
clarkb | yseterday you mentioned the change isn't quite ready for review yet. THis morning I noticed that the puppet jobs are unhappy with it | 19:09 |
clarkb | Anything we can do to help or will you send up the signal flare when we should look at it? | 19:09 |
ianw | ok; so to catch people up, we only support letsencrypt for .opendev.org domain names, because we use domain authentication and openstack.org ishosted in rax which needs a different path | 19:10 |
clarkb | #link https://review.opendev.org/#/c/658281/ Ansible deployed mirrors so they can be LetsEncrypted more easily | 19:11 |
ianw | so to https mirrors we need .opendev.org names for them | 19:11 |
ianw | my first thought was that we could do something like point records to the existing mirrors, and deploy certs | 19:11 |
ianw | but it turned out to not really be KISS but puppet hacking and just going what felt like the wrong way | 19:12 |
ianw | so i'd propose we just start a new mirror server in each region and manage it fully via ansible | 19:12 |
ianw | which is ultimately 658281 above | 19:13 |
ianw | there's some intermediate steps below that | 19:13 |
ianw | #link https://review.opendev.org/658930 -- signs fake letsencrypt cert with a fake CA so apache can start unmodified in test environment | 19:13 |
ianw | #link https://review.opendev.org/652801 -- wires in handlers to be called when letsencrypt renews certs | 19:13 |
clarkb | plan seems reasonable. Then we can have the new mirrors running with tls enabled then update the site var for zuul to talk to the opendev mirrors instead | 19:14 |
ianw | fungi would particularly like your eyes on 658930 | 19:14 |
clarkb | oh there is a new ps on the handlers change (I'll rereview it) | 19:14 |
fungi | starred, thanks | 19:14 |
ianw | yep, and as mentioned in the CL, it should be ok to CNAME the existing mirrors to the new mirrors, it's setup as http/https | 19:14 |
clarkb | cool that gives us extra betls and suspenders | 19:15 |
ianw | i wasn't quite sure about the other ports; would they be switched to ssl, or do we need to have a similar thing where ssl is a separate port? | 19:15 |
clarkb | ianw: I think we can safely update the docker ports to be ssl because docker doesn't take urls | 19:16 |
clarkb | instead you just give it a flag if it is ok to not do ssl | 19:16 |
*** dklyle has joined #openstack-meeting | 19:16 | |
clarkb | but for the main mirror at 80 we probably want a corresponding 443 so that stuff can opt into https for that | 19:16 |
ianw | i also considered docker for deployment, but i didn't see where it really fit here. the mirrors must be in each region specifically; i mean that's the whole point | 19:16 |
clarkb | then after the initial switch we can make 80 redirect to 443 | 19:16 |
ianw | the main thing this is doing is being an afs client, something that doesn't make sense in a container as it installs kernel modules to the host system | 19:17 |
clarkb | that and run a very stable web server | 19:17 |
clarkb | I agree that ansible alone is probably sufficient for this | 19:17 |
clarkb | (and likely preferable) | 19:17 |
ianw | at that point, the container is just a webserver with a lot of stuff mapped into it, which doesn't seem any different to just "apt-get install" ing it | 19:18 |
ianw | right, yeah we don't even have complex cgi dependencies or anything; just that one vhost | 19:18 |
clarkb | I think if we wanted to build apache or $webserver ourselves containers would make sense but the distro version has been fine so far | 19:18 |
fungi | yeah, i think we should push to wrap things in containers when it makes sense to do so, and just rely on distro packages for stuff on the server when it doesn't | 19:18 |
*** dklyle has quit IRC | 19:19 | |
*** david-lyle has joined #openstack-meeting | 19:19 | |
*** pcaruana has quit IRC | 19:19 | |
fungi | don't container merely for containering's sake | 19:19 |
ianw | cool; that was my only concern, that people might think it needs to be wrapped up | 19:19 |
ianw | so in short, should be ready for review. if it's looking good, we can bring up a single node first and check it out, and even switch just one node in with a CNAME from openstack.org and monitor it for a bit | 19:20 |
clarkb | oh I like that idea | 19:20 |
*** jamesmcarthur has joined #openstack-meeting | 19:20 | |
fungi | me too | 19:20 |
clarkb | +1 from me on that. I can review the stack while waiting on zuul puppet 4 things to happen | 19:20 |
*** slaweq has joined #openstack-meeting | 19:21 | |
clarkb | alright anything else on this or should we move one? | 19:21 |
clarkb | s/one/on/ | 19:21 |
ianw | nope, that's it, thanks! | 19:21 |
clarkb | #topic OpenDev | 19:22 |
*** openstack changes topic to "OpenDev (Meeting topic: infra)" | 19:22 | |
clarkb | If you haven't already, please read my ptg summary as it covers some the thoughts we had during the PTG for opendev next steps (largely around how to delegate responsibility for stuff to users | 19:23 |
clarkb | The other major todos we have are the cgit cluster cleanup (which I've got on my todo list), just trying to convince myself we don't have a major gitea issue with the 404s mriedem points out before I commit to that | 19:23 |
clarkb | Also we want to udpate gitea to 1.8.x but our tests are failing on what appears to be a valid issue pointed out by the tests | 19:24 |
clarkb | if anyone is able to look at that it would be helpful (I can probably get to it after cgit farm is cleaned up) | 19:24 |
clarkb | I think we are still likely to be on track for a end of month downtown to do fixup project renames | 19:25 |
clarkb | we should prep rename changes for the projects under infra/opendev control that were missed | 19:25 |
clarkb | (I say all that realizing we are still somewhat short staffed for a bit so we'll get what we get done done) | 19:26 |
*** radeks_ has quit IRC | 19:26 | |
clarkb | graham (kata dev) had good feedback on some gitea UI weirdness | 19:27 |
clarkb | I'll try to push that feedback upsteram if graham chooses not to | 19:27 |
*** jamesmcarthur has quit IRC | 19:27 | |
clarkb | Anything else from the crowd on opendev related items? | 19:28 |
*** jamesmcarthur_ has joined #openstack-meeting | 19:28 | |
clarkb | Sounds like no. Lets move on | 19:29 |
clarkb | #topic Storyboard | 19:29 |
*** jamesmcarthur has joined #openstack-meeting | 19:29 | |
*** openstack changes topic to "Storyboard (Meeting topic: infra)" | 19:29 | |
clarkb | diablo_rojo: still here? I noted last week that there was a painpoints session with good feedback and that you all had a bug cleaning sprint | 19:29 |
clarkb | Anything else to add re storyboard since the summit/ptg/forum? | 19:30 |
fungi | diablo_rojo posted a denver summary for it to the... openstack-discuss ml? | 19:30 |
fungi | yeah that's it | 19:30 |
diablo_rojo_phon | Yes the discuss list | 19:30 |
diablo_rojo_phon | Finally. | 19:30 |
clarkb | #link http://lists.openstack.org/pipermail/openstack-discuss/2019-May/006214.html | 19:30 |
diablo_rojo_phon | Basically nothing was a surprise. | 19:30 |
fungi | it's prompted some follow-up discussion on the ml as well | 19:31 |
diablo_rojo_phon | The largest outcome was that we should do two different onboardings. One for users. | 19:31 |
diablo_rojo_phon | And one for development | 19:31 |
clarkb | ya we've had similar ideas for infra users and admins/devs | 19:32 |
fungi | also the telemetry team is ready to move their tracking to sb.o.o now that the new maintainers have obtained control over the existing lp projects to be able to wind them down there | 19:32 |
diablo_rojo_phon | Yay! | 19:33 |
*** jamesmcarthur_ has quit IRC | 19:33 | |
diablo_rojo_phon | Swift also wants a test migration. | 19:33 |
diablo_rojo_phon | Which is on my to-do list for this week. | 19:33 |
clarkb | is the -dev server happy yet? | 19:33 |
clarkb | fungi: ^ you were probably the last person looking at that. Did you decide to just start over? | 19:34 |
fungi | as in manually renaming the projects in it? i think we should probably just stop having puppet autocreate project-groups on sb-dev but no i haven't found time to work on that yet | 19:35 |
*** yamamoto has joined #openstack-meeting | 19:35 | |
fungi | stop having puppet autocreate projects on sb-dev too probably | 19:35 |
clarkb | the db migration puppetry is broken currently. Not sure if t hat will impact diablo_rojo_phon's ability to do a test migration for swift | 19:35 |
diablo_rojo_phon | ..sounds like it would | 19:36 |
fungi | it shouldn't. just have to manually create any projects and project-groups you want to try importing into | 19:36 |
fungi | which would have been the case regardless because they're not flagged to use-storyboard in projects.yaml anyway | 19:36 |
diablo_rojo_phon | Oh okay. | 19:36 |
clarkb | got it | 19:36 |
diablo_rojo_phon | I think that's how I was doing it before. | 19:36 |
fungi | what i'm talking about abandoning is a puppet exec we currently run which creates any missing projects and project-groups in sb-dev for projects marked as using (production) storyboard already | 19:37 |
fungi | that's of very limited utility anyway given how we've actually been using sb-dev | 19:37 |
clarkb | should update the project rename playbook too to remove the renames there? | 19:38 |
fungi | we never included them in the project rename playbook, which is why the puppet exec is now broken | 19:38 |
fungi | (unless someone added it very recently) | 19:38 |
*** rfolco|dentist is now known as rfolco|ruck | 19:39 | |
clarkb | my change (whcih I thought had merged) https://review.opendev.org/#/c/655476/3/playbooks/rename_repos.yaml added it as the alternative fix for this problem | 19:40 |
fungi | ahh | 19:40 |
clarkb | The change hasn't merged though (we should really get that in well before we try to do more project renames...) | 19:40 |
clarkb | I can remove it if you prfer and push a new ps. Then you can remove the puppet exec safely | 19:40 |
*** yamamoto has quit IRC | 19:40 | |
fungi | well, given that the rename process simply updates database rows when it finds matches, i don't think it will hurt (it just won't usually do anything for nonexistent ones) | 19:40 |
clarkb | ok I'll leave it as is then I guess | 19:41 |
*** david-lyle has quit IRC | 19:42 | |
clarkb | Sounds like that may be it for storyborad | 19:43 |

clarkb | #link https://etherpad.openstack.org/p/201808-infra-server-upgrades-and-cleanup Trusty server upgrades | 19:43 |
clarkb | I'm hoping that I'll be able to dedicate a good chunk of next week to this once I've climed out of the everything else backlog | 19:43 |
clarkb | we are very near the end | 19:43 |
clarkb | fungi said he can delete the old groups servers in the near future too | 19:44 |
fungi | yup, already on my to do list | 19:44 |
clarkb | Has anyone been working on the other servers still on the list? if so anything we can help with? | 19:44 |
ianw | no but i really should look at ask ... i think it's ready to go | 19:45 |
clarkb | ianw: that would be great | 19:46 |
clarkb | #topic Open Discussion | 19:46 |
*** ijw has quit IRC | 19:46 | |
*** openstack changes topic to "Open Discussion (Meeting topic: infra)" | 19:46 | |
clarkb | We have ~14 minutes for other topics if we want to keep talking here | 19:46 |
fungi | on opendev topics, did we mention the next batch project rename schedule? | 19:47 |
fungi | last week we said last friday of may? | 19:47 |
clarkb | fungi: yup and yup | 19:47 |
clarkb | the 31st | 19:47 |
clarkb | I think we are still on track for that assuming we get the rename fixes merged and can generate the list of things we need to rename | 19:48 |
fungi | cool | 19:48 |
fungi | that weekend is a holiday in au, ie and nz | 19:48 |
clarkb | my kids have a fourth birday on the 2nd | 19:49 |
clarkb | but the size of this would be much smaller | 19:49 |
clarkb | so I'm more comfortable doing it friday and nnot needing to work all weekend like last time | 19:49 |
fungi | weekend before it is a holiday in uk and us, weekend before that is a holiday in ca ;) | 19:49 |
fungi | so yeah, gonna be a holiday weekend no matter what | 19:50 |
* fungi needs all the countries and religions of the world to sync their holiday schedules for his convenience | 19:50 | |
clarkb | That would be convenient | 19:51 |
clarkb | Anything else? | 19:52 |
clarkb | I'll end the meeting in a minute or two if not | 19:52 |

b1airo | o/ | 21:13 |
oneswig | I'll admit I'm troubleshooting openvpn weirdness on the side... | 21:14 |
martial | Well I saw no messages for 3 minutes so I was not sure either | 21:14 |
oneswig | hey b1airo | 21:14 |
oneswig | #chair b1airo | 21:14 |
openstack | Current chairs: b1airo martial oneswig | 21:14 |
b1airo | Just realised my calendar is out due to daylight saving changes, hence the lateness | 21:14 |
jmlowe | https://threatpost.com/linux-kernel-remote-code-execution/144713/?utm_source=newsletter&utm_medium=Email&utm_campaign=tp_daily_digest_14_5_2019 | 21:14 |
janders | martial: I saw last week you mentioned good conversations with the RHAT folks | 21:14 |
jmlowe | that's got my attention ATM | 21:14 |
janders | who was that? | 21:14 |
jmlowe | and for extra fun Intel has a new exploit, zombieload | 21:15 |
janders | I'm wondering if it's the guys I'm talking to as well, perhaps we can join forces pushing the HPC agenda | 21:15 |
martial | It was Erwan Gallen | 21:15 |
martial | He is seeing how RedHat can bring efforts and code to help the HPC side | 21:16 |
b1airo | OpenStack Summit = new high impact vulnerability disclosures | 21:16 |
martial | I need to follow up so he join our slack too | 21:16 |
janders | cool! thank you | 21:17 |
janders | I think it is a great opportunity for both RHAT and us | 21:17 |
janders | so let's keep fighting the good fight | 21:17 |
jmlowe | b1airo: it's the sobering reality after returning from the summit | 21:17 |
janders | (the subscription model as it stands isn't the best fit for HPC and HPC scale, that's one of the issues I see) | 21:17 |
janders | https://access.redhat.com/security/vulnerabilities/mds?sc_cid=701f20000012nDXAAY& | 21:17 |
janders | (further to the exploit comments) | 21:17 |
martial | They want to help and he is willing to put coders on a problem with the community’s help | 21:18 |
martial | And their code is open source after all | 21:18 |
jmlowe | janders: those are collectively being called zombieload I think | 21:18 |
trandles | oneswig: sorry, was AFK on the phone...not tried ramdisk driver, should be in the next two weeks | 21:19 |
janders | jmlowe: agreed | 21:19 |
oneswig | trandles: no problem, good to hear it | 21:19 |
*** jamesmcarthur has joined #openstack-meeting | 21:20 | |
trandles | working through the logistics of getting a couple collaboration accounts set up here for outsiders, nuke-n-pave my testbed to reset for ironic work, etc. | 21:20 |
oneswig | Sound interesting, but careful with your choice of metaphor | 21:21 |
b1airo | :-) | 21:21 |
trandles | HA! | 21:21 |
trandles | Also, saw the latest Singularity root exploit and had a chuckle :P | 21:21 |
oneswig | The news over here is we got our first Kata study published | 21:22 |
oneswig | #link I/O performance of Kata https://www.stackhpc.com/kata-io-1.html | 21:22 |
oneswig | trandles: what's that? | 21:22 |
martial | Oh cool | 21:23 |
trandles | https://github.com/sylabs/singularity/releases/tag/v3.2.0 | 21:23 |
trandles | their CVE link is wrong, you either get the reserved message or a joomla CVE using the same number | 21:24 |
oneswig | how careless | 21:24 |
trandles | scratch that, google brought up 2018-11328 instead of 2019 | 21:25 |
trandles | :( | 21:25 |
*** dklyle has joined #openstack-meeting | 21:27 | |
b1airo | Gah, glad we haven't committed one way or other yet | 21:27 |
trandles | seems like Kata has a LOT of I/O optimization to do | 21:28 |
b1airo | trandles: have you guys considered a Zun plugin for CharlieCloud ? | 21:29 |
oneswig | trandles: a lot indeed. It's moving fast and should get a lot of the low-hanging fruit in the next release. | 21:29 |
oneswig | trandles: it has a very long way to go though | 21:29 |
trandles | b1airo: not really | 21:29 |
oneswig | In other post-summit follow-up, I mailed Jonathan Bryce about supporting a white paper on private / hybrid cloud advocacy for research computing, no response as yet, but I'll follow up | 21:29 |
oneswig | brb | 21:30 |
trandles | we've been focusing on some Slurm integration | 21:30 |
*** jamesmcarthur has quit IRC | 21:30 | |
jmlowe | plan9 is always going to kill I/O | 21:30 |
trandles | among other things (like at 100% truly unprivileged container build without docker as a dependency) | 21:30 |
*** enriquetaso has quit IRC | 21:31 | |
trandles | we've been digging into Buildah since it's billed as "unprivileged build" using Dockerfiles...and it relies on setuid binaries and has Docker as a dependency buried in all the golang :( | 21:31 |
*** jamesmcarthur has joined #openstack-meeting | 21:31 | |
b1airo | Nice o_0 | 21:32 |
janders | bad developers go to dependency hell after they die | 21:33 |
oneswig | trandles: similarly I saw that podman claims to offer an unprivileged container runtime but not until the next release of RHEL | 21:34 |
trandles | oneswig: in RHEL 8, which is GA | 21:34 |
b1airo | The really bad ones go to dll hell :-P | 21:34 |
oneswig | trandles: ah is it? Thanks | 21:34 |
trandles | I also heard that RHEL is offering RHEL-based base containers with RHEL 8 that can be redistributed, but haven't confirmed it | 21:34 |
janders | next as in 7.7, 8 or 8.1? | 21:35 |
janders | sorry scratch that | 21:35 |
trandles | I know podman is being looked at here, but I'm not the one doing the looking and haven't followed-up yet | 21:35 |
*** jamesmcarthur has quit IRC | 21:36 | |
*** enriquetaso has joined #openstack-meeting | 21:37 | |
oneswig | trandles: going from https://developers.redhat.com/blog/2019/02/21/podman-and-buildah-for-docker-users/ | 21:37 |
oneswig | "You can also run Podman from your normal non-root user in Podman 1.0 on Fedora. RHEL support is aimed for version 7.7 and 8.1 onwards." | 21:38 |
oneswig | That was the story in February | 21:38 |
trandles | ah yeah, thx for the link | 21:39 |
trandles | I've heard of this blog post but hadn't read it myself | 21:39 |
*** jamesmcarthur has joined #openstack-meeting | 21:40 | |
oneswig | It's somewhat biased :-) | 21:40 |
trandles | just a tad | 21:40 |
martial | We can always let them know | 21:41 |
trandles | martial: I haven't contacted Erwan yet but plan to | 21:41 |
trandles | thx for the introduction | 21:41 |
martial | You walked as I was talking about you:) small world | 21:42 |
*** jamesmcarthur has quit IRC | 21:44 | |
oneswig | jmlowe: that exploit on threadpost is not quite as bad as the whatsapp one... | 21:44 |

*** bbowen has joined #openstack-meeting | 21:48 | |
oneswig | I think everyone here's on the Slack channel set up by martial - anyone want the sign-up link? | 21:48 |
trandles | btw - ZombieLoad is scary | 21:49 |
trandles | tl;dr disable hyperthreading | 21:50 |
*** dklyle has quit IRC | 21:50 | |
trandles | ZombieLoad can be triggered in virtual machines, which are meant to be isolated from other virtual systems and their host device. Daniel Gruss, one of the researchers who discovered the latest round of chip flaws, said it works “just like” it does on PCs and can read data off the processor. That’s potentially a major problem in cloud environments where different customers’ virtual machines run on the same server h | 21:51 |
janders | oneswig: I think I will need to switch accounts - can I re-invite myself on a different email address? | 21:51 |
oneswig | Sure - martial is the admin, if you need super-powers :-) | 21:52 |
janders | ok! | 21:52 |
jmlowe | ugh, I hadn't read that carefully to see the exploitable in vms part | 21:52 |
trandles | the abstract of the whitepaper (https://zombieloadattack.com/zombieload.pdf) says "We discuss both short and long-term mitigation approaches and arrive at the conclusion that disabling hyperthreading is the only possible workaround to prevent this extremely powerful attack on current processors." | 21:53 |
jmlowe | I saw Intel was rolling new microcode, so that's not sufficient? | 21:53 |
trandles | dunno | 21:54 |
*** mattw4 has quit IRC | 21:54 | |
martial | Let me get the link again | 21:55 |
martial | here https://join.slack.com/t/os-scientific-sig/shared_invite/enQtNjIyOTU1NjU3Njg1LTVjY2QzNTkyMjVmZjIzNjI2MDYzNjcxMzExMDY5NDQ0MTc1NGRjMzk2ZTE2N2VjZjJiMzlmMGM2MGJjZjY4YzA | 21:56 |
martial | janders, I think you can change your email from within the slack itself | 21:57 |
janders | ok, thank you martial | 21:57 |
martial | of note, Blair and Stig are also admin on the slack | 21:59 |
oneswig | trandles: If I read this right, a user process can access privileged memory, data from other VMs or the hypervisor, even SGX protected regions? | 21:59 |
martial | and on that we are at the end of the hour | 21:59 |
janders | thanks guys! | 21:59 |
oneswig | Thanks all and good night :-) | 22:00 |
martial | seems scary indeed | 22:00 |
