ohsixany idea why bug 711429 is nonpublic?03:00

ohsixmarking a public bug a duplicate of a private one suxxx03:01
bjfohsix, i've added a somment asking why it's private03:08
ohsixok, thanks03:08
bjfohsix, not sure why you are asking in the kernel channel though, you might get more satisfaction in #ubuntu-devel03:08
ohsixwell, eyes; most things i have to ask about are fleeting in interest :]03:09
ohsixit being private is almost good for me; then i don't have to follow up on the public one i posted03:09
bjfohsix, it was marked a duplicate by a bot03:12
ohsixright03:12
bjfohsix, i'm trying to find out who "ownes" the bot, it shouldn't automatically mark public bugs duplicates of private bugs03:13
ohsixkeen, i've had it happen two or three times; wondered why it took that path03:14
bjfohsix, there's probably a way to file a bug against the bot03:14
bjfohsix, email sent, i'm guessing this will get fixed up fairly quickly03:18
ohsixmuch appreciated03:18

ubot2apw: The Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2, and KVM 83, when the Intel VT-x extension is enabled, allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via vectors related to instruction emulation.

tgardnersconklin, I pushed a bunch of CVE updates on the maverick ti-omap branch. since I cherry-picked them from maverick master-next, do you think we need to go through the mailing list ACK process? I'm thinking not.14:40
=== shadeslayer is now known as shadeslayer_

apwtgardner, is that a .33 branch?14:47
tgardner.3514:47
tgardnerI went through all of maverick master-next and cherry-picked the CVE patches14:47
apwtgardner, i think we should take an ack on maverick to mean an ack for all 2.6.35 based branches; if they arn't a rebase then i'd expect them to get it via cherry without additional comment14:50

lagkamal: I'm playing around with GPG keys (only because I have to :))15:04
lagWhat's the difference between full and ultimate?15:05
lagAnd how do I change my new uids from unknown to full/ultimate?15:06
kamallag: http://www.queen.clara.net/pgp/art4.html15:06
lagOh, they're already ultimate. They were unknown before?15:06
kamallag: you can mark other people's keys as "full" trust, meaning that you have a high level of trust in their signatures when they appear on other keys ...15:07
kamallag: you should mark (only) your own key as "ultimate", so that gpg will realize that it should absolutely positively trust any key that you yourself have signed.15:07
lagkamal: Did you 'make' me do that for you when you signed my keys?15:07
kamallag: when you create your own key, gpg automatically assigns it "ultimate"15:08
lagkamal: Make them 'full' I mean15:08
