Unfortunately syzkaller is not potentially portable to 1.4 as we have lots of external dependencies. > Check out the doc for how to use it and some of the more interesting > bits of the port: > > https://github.com/akaros/go-akaros/blob/akaros/README.akaros > > My favorite is Usys: a mechanism to call into GCC / 2LS C code from Go > code, similar to making a syscall on other OSes.

Sounds like something else to stress test ;) E.g. for fuchsia we now auto-generate syzkaller descriptions from fidl service descriptions, so syzkaller knows how to connect to system services and can talk to them with realistic contents.

Re: [akaros] Go 1.4
Nice! Well done! In addition to the ‚.‘, dont forget about the fake UTF ‚/‚ symbol for symbols that match to packages like „runtime/cgo“ as symbols in the C Code. Barret Rhoden schrieb am Do. 6.
