It will also help to assess what's covered and what's missing. - System call descriptions. `sys/freebsd/*.txt` is a dirty copy from `sys/linux/*.txt` with everything that does not compile dropped. We need to go through syscalls and verify/fix/extend them, including devices/ioctls/etc. - Currently only `amd64` arch is supported. Supporting `386` would be useful, because it should cover compat paths. Also, we could do testing of the linux-compatibility subsystem. - `pkg/csource` needs to be taught how to generate/build C reproducers. - `pkg/host` needs to be taught how to detect supported syscalls/devices. - `pkg/report`/`pkg/symbolizer` need to be taught how to extract/symbolize kernel crash reports. - We need to learn how to build/use debug version of kernel. +- KASAN for FreeBSD would be useful. +- On Linux we have emission of exernal networking/USB traffic into kernel using tun/gadgetfs. Implementing these for FreeBSD could uncover a number of high-profile bugs. - Last but not least, we need to support FreeBSD in `syz-ci` command (including building kernel/image continuously from git). |
