OpenBSD Errata: January 27th, 2019 (mincore)

26 January, 2019 by tj@openbsd.org | openbsd

Errata patches for the kernel have been released for OpenBSD 6.3 and 6.4.

The mincore() system call can be used to observe memory access patterns
of other processes.

Binary updates for the amd64, i386, and arm64 platforms are available
via the syspatch utility. Source code patches can be found on the
respective errata page:

  https://www.openbsd.org/errata63.html
  https://www.openbsd.org/errata64.html

As these affect the kernel, a reboot will be needed after patching.
