Re: radiusd(8) bsdauth crashes if user authenticates with a mechanism ":style" and group checking on

2019-12-16 Thread Dennis Lindroos 
Hi guys,

Brilliant! Didn't know about strcspn() myself.. Now i tested and confirmed
to work (both with and without auth style). Let me know if there's anything
i can help.
BR,
Dennis ^^ OpenBSD/Finland (alpha,x86) since ca 2000 ^^

uvm_fault Panic on recent -current

2019-12-16 Thread Matthias Schmidt 
Hi,

My Thinkpad T450s paniced with uvm_fault while fetching a large git
repository to /usr/src.  I had a read-only NFS share mounted during the
git pull and copied a file over to my local disk in the background.

The panic trace transcribed by hand.  I can provide a photo upon
request:

uvm_fault ()

The disk/mount looks as follows:

softdep)
/dev/sd1d on /tmp type ffs (local, noatime, nodev, nosuid)

Let me know if you need more details or if I should test something.
Cheers

Dec 15 snapshot made t410 graphics unusable

System  : OpenBSD 6.6
Details : OpenBSD 6.6-current (GENERIC.MP) #531: Sun Dec 15

Architecture: OpenBSD.amd64
Machine : amd64
>Description:
After upgrading to Dec 15 snapshot, in my thinkpad t410 image is
so distorted that it's impossible to read the text.  This
happens in both, X11 and tty console, so I have to ssh login
from another machine in my LAN to operate (however there are
those who still argue full graphics support in tty console is a
wonderful thing.)

I'm not completely sure, but I think these lines already appeared
in dmesg before this issue happened (I mean on previous
snapshots):

   [drm] *ERROR* CPU pipe A FIFO underrun
   [drm] *ERROR* PCH transcoder A FIFO underrun

>How-To-Repeat:
Boot the machine and wait till drm is loaded.
>Fix:
I don't know.

I can confirm the bug is fixed, thanks.
