>Description:

ps doesn't work on crash dumps since the kernel switched to kauth
because libkvm still tries to read process credentials the pre-kauth way.


>How-To-Repeat:
	run ps on a crash dump:

# ps -axl -N netbsd.0 -M netbsd.0.core 
ps: can't read proc credentials at 0xc90d63e4: Undefined error: 0


>Fix:
	teach libkvm about kauth.
