OpenBSD Errata: January 27th, 2019 (mincore)
26 January, 2019 by email@example.com | 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.
