lib/fuzzing: fuzz_sddl_parse: allow non-round-trip with long strings

2023-09-26T23:45:36+00:00

There is a borderline case where a conditional ACE unicode string
becomes longer than the SDDL parser wants to handle when control
characters are given canonical escaping. This can make the round trip
fail, but it isn't really a problem.

lib/fuzzing: LLVMFuzzerTestOneInput() takes const uint8_t*

2023-08-08T04:39:38+00:00

We have been using `uint8_t *`, which works fine as far as
linking goes, but leads fuzz target developers to sometimes
forget why they can't just modify the passed in string instead of
copying it for modification (e.g. to NUL-terminate).

lib/fuzzing: add fuzzer for sddl_parse

2023-04-28T02:15:36+00:00

Apart from catching crashes in the actual parsing, we abort if the SD
we end up with will not round trip back through SDDL to an identical
SD.
