Hi, Due to an oversight on my part, seL4 10.1.0 was released without passing the full verification test suite.
We have no reason to believe that there is any problem in the verified parts of this seL4 version. The test that failed is part of the binary translation validation, which produces a dataflow graph from the Isabelle/HOL model of the C code, and then attempts to automatically prove a refinement relation between the C and that dataflow graph. The failure occurred in boot code, which in any case is currently not verified. The failure does not mean that there is any problem with the C code. Most likely, it just means that some new code uses some C idiom which is currently not handled by the automatic translation process. All other components of the verification test suite pass, including security proofs and functional correctness proofs for the Isabelle/HOL model of the C code. Nevertheless, we intend to rectify this failure as soon as possible, and we'll make further announcements when we understand what happened. I want to reiterate that this was entirely my fault, and was not at all Kent's fault.
