Kathryn,
@eiais, did not bypass code review. She didn't disrupt anyone's work. She didn't target an individual. She didn't violate any policy I'm aware of. She linked to an NLRB notice from an extension that exists to show links to policies. This only makes sense as retaliation.https://twitter.com/eiais/status/1206937188409044993 …Show this threadThanks. Twitter will use this to make your timeline better. UndoUndo -

Kathryn was on my team. There was zero reason why she should have asked anyone else on the team for authorisation to make changes to this extension. That's not how we do things.https://twitter.com/alibreland/status/1206979396957065216 …

Checking for consensus in the infosec community: Would you want your front door lock to be controlled by an app and cloud service? This would be online, not just local bluetooth. RTs for reach appreciated.

Hello. As one of the organizers of DEF CON, I can say that the challenges to securing our elections are no longer technical — we know how to fix it. The problems are now purely political — people in power benefit from these vulnerabilities & don’t want things to get fixed.

After 1 hour of looking at my new smart lock, I am now able to remotely unlock every front door in the apartment complex.

That was 4 days ago and it hasn't broken again yet. AMD released new microcode and then pulled it due to other bugs, so no real fix yet. Applications can still call RdRand from userspace so who knows what else will break.

4b. Try to rebuild grub.cfg from the Fedora 29 USB. Nope, that uses RdRand too. It's a complex config and typing in commands at the grub prompt fails. Hours later, piece together a working cfg from the raw /boot/efi partition. Booted with nordrand, grub2-mkconfig works again.

4. Run grub2-mkconfig > grub.cfg add that nordrand arg. Bad move. That probes LVM devices which also uses RdRand. System gets unresponsive (all the blocked kworkers?) and I reboot, but now grub.cfg is empty so grub doesn't know how to load anything. No backup copy.

3. Time passes. I set up Wireguard. It receives a handshake packet and calls get_random_u32 which blocks a kernel worker forever. I forgot to include nordrand in kernel args while configuring VFIO. Need to add that to the default config.

2. Can't mount /home. It's LUKS2 while root is v1. cryptsetup just hangs forever on LUKS2 volumes. Some debugging later, it's getting stuck on a call to libjson-c so we rebuild that without RdRand and all's well.

1. Total failure to boot. We forgot about the known systemd issue. Boot a Fedora 29 live USB, chroot the system and install the patched systemd from https://copr.fedorainfracloud.org/coprs/jerbear64/systemd-zen2/ …. OK, should be fine now?

Thread: Let's make a list of all the fun ways AMD's Zen 2 RdRand failure has messed up this Fedora 30 system. The instruction reports success (CF=1) but returns 0xFFFFFFFFFFFFFFFF (almost?) every time.

current status: can't mount /home because the new 3900X's RdRand instruction fails and Fedora's libjson is compiled to use RdRand... cryptsetup needs libjson for LUKS2? (╯°□°)╯︵ ┻━┻

I have to say something positive for once: I bought a Miata recently and it’s everything the internet said it would be. Absolutely brilliant fun.
