Add vmctl send and vmctl receive
As we see from the commit message, new developer Pratik Vyas (pd@) adds the ability to do paused VM migrations for VMM.
Mike Larkin also writes on Twitter:
#OpenBSD vmctl(8) : vmctl send myvm | ssh mlarkin@somewhere.com vmctl receive Yes, it's that easy.
Ed: this is *paused* migrations, not live migrations.
OpenBSD and the modern laptop
Over at his blog, Undeadly co-editor Peter Hansteen describes the experience of installing OpenBSD-current on a new laptop.
The article, OpenBSD and the modern laptop, goes into some detail on the install procedure, and hits only minor snags even when using modern and recent additions such as UEFI boot.
The conclusion is that OpenBSD i [...]

Kernel relinking status from Theo de ...
As you may have heard (and as was mentioned in an earlier article), on recent OpenBSD snapshots we have KARL, which means that the kernel is relinked so each boot comes with a new kernel where all .o files are linked in random order and with random offsets. Theo de Raadt summarized the status in a message to the (Read more...)
On the Insecurity of TIOCSTI
Theo de Raadt (deraadt@) provided some history on the insecurity of TIOCSTI [simulate typed input on terminal], with a proposal to disable it on OpenBSD:
[...] there\'s always been the risk
that a program manages to retain tty association beyond it\'s intended
lifetime, and then it can perform injections with TIOCSTI.
So I\'ve always w [...]

at the protocol functions and refactored them. Especial [...]
