Kernel syspatches will soon be smaller thanks to KARL
Undeadly.org - August 21, 2017, 6:33 pm UTC

It almost went unnoticed due to the 6.2-beta announcement, but Antoine Jacoutot (ajacoutot@) just commited a very useful update to syspatch. In this commit, the groundwork is done for having syspatch update only the kernel object files that have changed. Due to KARL, the scheme to relink the kernel for each reboot, it makes sense to save space and bandwidth that way.


The commit message reads:

RETGUARD, the OpenBSD next level in exploit mitigation, is about to debut
Undeadly.org - August 19, 2017, 10:59 pm UTC

In a message to the tech mailling list, Theo de Raadt(deraadt@) offered a preview of the next big thing in exploit mitigation, dubbed RETGUARD:



This year I went to BSDCAN in Ottawa. I spent much of it in the
'hallway track', and had an extended conversation with various people
regarding our existing security mitigations and hopes for new ones in
the future. I spoke a lot with Todd Mortimer(mortimer@). Apparently I told him
that I felt return-address protection was impossible, so a few weeks
later he sent a clang diff to address that issue...

t2k17 Hackathon Report: Ted Unangst OpenBSD with more ptys
Undeadly.org - August 18, 2017, 5:24 am UTC

The second report from the just completed t2k17 hackathon
comes from Ted Unangst (tedu@), who writes:



I did a bit of this and that, but the project that probably has the most

history behind it that goes back to the early days of unix.

Unusually I had basically nothing to do with organizing this year, I
let krw@ do all the dirty work, which was good since life has been a
