I hope this isn't so basic that it belongs on netbsd-help, or so
involved that I should send a PR. Feel free to point me in the correct
direction if needed.
* New 2.0.2 system
* veriexecctl(8) fails with EFAULT in do_ioctl().
My troubles began with 2.0 on a different system, where /etc/signatures
seemed not to be loaded. I tried manually running veriexecctl(8) after
bootup, was discouraged by EPERM, presumed it was newbie-itis, and
decided to try again another time.
Fast forward 3-4 months to today. I compiled the kernel with "options
insecure" to hold securelevel at -1. Now when I run veriexecctl(8)
after boot, EPERM is gone (as expected), but has been replaced by
The system has compiled several kernels flawlessly, so I don't think
it's wonky CPU/MB/PS/RAM, but I won't swear to it 100%. I'll post dmesg
output if that would be useful, but my gut feeling tells me there might
be something amiss with the VERIEXECLOAD ioctl() handler.
Any quick suggestions or comments, or should I dig into kernel source?
I hesitate to scream "broken!" re a major feature on a production
release, but am puzzled what else could be the culprit.
