The test generates a BPF with libseccomp API then runs a BPF simulator. The libseccomp commit 51c46f80c1edee863bbc4eb21b03decc44e69a45 ("all: block negative syscall numbers from the filter") seems to indicate this is fixing and testing problems on the filter (which I read as BPF filter), so this is unlikely a kernel problem.
However, it might be uncovering a libseccomp bug on s390.
