News Roundup
Google Summer of Code 2020: [Final Report] Enhancing Syzkaller support for NetBSD (https://blog.netbsd.org/tnf/entry/google_summer_of_code_20202)
Sys2syz would give an extra edge to Syzkaller for NetBSD. It has a potential of efficiently automating the conversion of syscall definitions to syzkaller’s grammar. This can aid in increasing the number of syscalls covered by Syzkaller significantly with the minimum possibility of manual errors. Let’s delve into its internals.
How the OpenBSD -stable packages are built (https://dataswamp.org/~solene/2020-10-29-official-openbsd-stable-architecture.html)
In this long blog post, I will write about the technical details of the OpenBSD stable packages building infrastructure. I have setup the infrastructure with the help of Theo De Raadt who provided me the hardware in summer 2019, since then, OpenBSD users can upgrade their packages using pkg_add -u for critical updates that has been backported by the contributors. Many thanks to them, without their work there would be no packages to build. Thanks to pea@ who is my backup for operating this infrastructure in case something happens to me.
OPNsense 20.7.4 released (https://opnsense.org/opnsense-20-7-4-released/)
This release finally wraps up the recent Netmap kernel changes and tests.
The Realtek vendor driver was updated as well as third party software cURL,
libxml2, OpenSSL, PHP, Suricata, Syslog-ng and Unbound just to name a couple
of them.
