gzip does not set uid and gid anymore (because of pledge)

[Remi Locherer]

Hi

After upgrading a firewall to 5.9 I noticed that the ownership of logfiles
is not as I specified in newsyslog.conf. After newsyslog compressed the files
the ownership is always root:wheel.

I figured out that this is because gzip can not chown anymore since it was
pledged. The below patch fixes this.

Crash in softnet on SGI

[Jesse Darrone]

Hello All,

Synopsis: spurious crash in softnet
Category: kernel sgi
Environment:

  System: OpenBSD 6.0
  Details: OpenBSD 6.0-beta (GENERIC-IP22) #664: Sun Jul 10 00:31:39 MDT 2016
  Architecture: SGI (MIPS64)
  Machine: Challenge S R5000

Description:

Machine seems to hang at (seemingly) random intervals.  This has
occurred on several recent snapshots including 10-Jul. I have
reproduced the issue on multiple systems, so it doesn't seem to be a
hardware issue.  It may not be relevant but the machines are running
an MTU of 1454 on sq1.

How-To-Repeat:

Seems to repeat itself given enough time, but I've not been able to tie it
to any specific sequence of events.  I will say that the machine typically does
not run longer than a day (though it has on occasion).

Fix: Unknown


sq1: receive FIFO overflow
