Catch up on Ben Dooks' talk from OSSEU 24, Vienna.
On one of our RISC-V projects, we were recently debugging a complex driver probing sequence in the U-Boot bootloader. Along the way we improved the debugging facilities available for U-Boot on RISC-V, specifically allowing developers and system integrators to see the callstack in the case that there is a crash during the early boot sequence.
As part of Codethink's interest in RISC-V I have been following the RISC-V kernel list. Whilst looking through the postings the following bug came up, titled: [syzbot] BUG: unable to handle kernel access to user memory in schedule_tail
Ben Dooks is our Senior Engineer and Open Source Consultant with more than 15 years’ experience contributing to Linux Kernel. Dooks joined Codethink 8 years ago, and since then he's been involved in a range of projects involving the Linux kernel, such as the MEG project, amongst others.
In 2018, Codethink worked with Lukas Bulwahn from BMW on a project investigating some core functionality of the Linux kernel that is relevant to safety considerations of an assumed system. We wanted to share some of our findings from this work, as it could prove useful to communities interested in using Linux in a safety-critical context.
