"no_generate": do not try to generate this syscall, i.e. use only seed descriptions to produce it. "no_minimize": do not modify instances of this syscall when trying to minimize a crashing program. +"no_squash": do not attempt to pass squashed arguments to this syscall. + Without that, the fuzzer will sometimes attempt to replace complex structures with arrays of bytes, + possibly triggering interesting mutations, but also making programs hard to reason about. "fsck": the content of the compressed buffer argument for this syscall is a file system and the string argument is a fsck-like command that will be called to verify the filesystem "remote_cover": wait longer to collect remote coverage for this call. |
