Here's the openbsd 5.9 radix routing table kernel panic. forgot to post the screenshot. They handle 0.0.0.0 diff.

How fast has anyone tricked out a Powerbook G4? Max ram, SSD, etc.
I'm using PowerPC for a few things..

@tech9 @efnetsent @YouTube i remember finding all the scene related accounts for mail and irc use on concentric& gblx. dorx. scheme=userdel

[Jonny Mnemonic @dent1zt]

@efnetsent @tech9 @acidphreak @octal ping me on otr so i know who you actually are.. @johnthreat aka netw1z sup

[Jonny Mnemonic @dent1zt]

/me wants an #ELF loader for #OSX -- could probably do all of it in userland. Apple's #APFS looks pretty likely to have bugs/vulns.

[Jonny Mnemonic @dent1zt]

@attractr oh, I have ported my old Linux / Solaris kernel patches (the redone unix security model) to their modern versions/BSD.

[Jonny Mnemonic @dent1zt]

@daniel_bilar sup with you man?

[Jonny Mnemonic @dent1zt]

Feel free to send the OpenBSD routing table kernel crash to them officially. I tweeted it, but didnt engage in mail. https://t.co/2h2GK9CacC

@attractr Moving tons of SDR, HW and tech hardware from a larger room to a smaller one.. I have almost-a-blog: https://t.co/iAkJEa2Tny

Dude that's hilarious/they look the part! https://t.co/1GFqltdhr4

Look everybody! You, too, can take over Federal land. Can't wait for round two. https://t.co/JDspEa0Ij5

@attractr That other Linux bug is definitely exploitable on Android for a root/jailbreak..
It's fairly nice.. you remember that one?

[Jonny Mnemonic @dent1zt]

@attractr hey, Linux and OpenBSD both had kernel vulns and bugs this month that werent vulns.. the bugs were lulz: https://t.co/iAkJE9Liw0

[Jonny Mnemonic @dent1zt]

@dent1zt *ip routing tables don't seem to mix, think obsd doesnt mark 0.0.0.0 the same as it does `default' because they didnt know they ==

[Jonny Mnemonic @dent1zt]

Lastly, here, I had an OpenBSD kernel bug that wasnt sec related either, so its also a funny bug.. https://t.co/iAkJE9Liw0 .. Obsd and iprou

[Jonny Mnemonic @dent1zt]

@dent1zt So I found more bugs in Linux but this one was revealable since it was 1) funny and 2) not a vulnerability for security. 1 POC done

[Jonny Mnemonic @dent1zt]

I ran pcifindrom.c after patching Linux arch/x86/mm/pat.c #ifdef->#ifndef to map all the physmem. 2 huge bugs rev'd & option roms 3x toomany

[Jonny Mnemonic @dent1zt]

@LKml by its x86, I'm stating that there is about 50 pieces of firmware running undereath ring 0... and Intel ME makes me comfy. PCI ROMS..

[Jonny Mnemonic @dent1zt]

Linux /dev/mem's brokenness that I gave out a fix to @lkml dates back to 2003... Nobody reverses their physmem. I inspect my mem.. its x86.

[Jonny Mnemonic @dent1zt]

https://t.co/I3GXCXLrpc fixes /dev/mem break on x86 (if you desire non-strict /dev/mem). Its a #ifdef->#ifndef fix.

[Jonny Mnemonic @dent1zt]

The Linux x86x64 /dev/mem thing being broken in arch/x86/mm/pat.c because of a #ifdef rather than #ifndef explained: https://t.co/iAkJEa2Tny

[Jonny Mnemonic @dent1zt]

I have an extaccton(1m) command and (2) that he has and can use... It can also be setup for some users,groups,roles,perm,noperm, etc.
