Description
This PR adds logic for handling relocated data - the write-callback inside of KFuzzTest targets will now parse the byte-array received from the client as the concatenation of a relocation table with a payload, such that all pointer arguments point to data within the payload. This effectively reduces the number of times that data needs to be copied from user-space to kernel to one.
The
kftf_parse_inputwill parse the data contained within the payload, and return a pointer to the first byte of the struct argument for the test case.
