We need to go through syscalls and verify/fix/extend them, including devices/ioctls/etc. -- Currently only the `amd64` arch is supported. It would be useful to support a 32-bit executor in order to cover 32-bit compatibility syscalls. +- System call descriptions. The initial list of FreeBSD system calls was a copy-and-paste of Linux's, and while they have been cleaned up over time they should be audited more carefully. We are also still missing many system call descriptions. - We should support fuzzing the Linux compatibility subsystem. -- `pkg/csource` needs to be taught how to generate/build C reproducers. +- We should provide instructions for fuzzing a FreeBSD system on ZFS - `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. -- KASAN for FreeBSD would be useful. +- KASAN and KCSAN 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. |
