A p-code injection library that uses a Ghidra client to generate/compile the injection p-code.
The InjectPayload objects produced by this library are just placeholders (see InjectPayloadGhidra). At the time of injection, final p-code is generated by the Ghidra client.
|
privatevirtual |
Allocate a new InjectPayload object.
This acts as an InjectPayload factory. The formal name and type of the payload are given, this library allocates a new object that fits with its storage scheme and returns the id.
sourceName | is a string describing the source of the new payload |
name | is the formal name of the payload |
type | is the formal type (CALLFIXUP_TYPE, CALLOTHERFIXUP_TYPE, etc.) of the payload |

|
virtual |
Get the array of op-code behaviors for initializing and emulator.
Behaviors are pulled from the underlying architecture in order to initialize the Emulate object which services the p-code script payloads.
Implements ghidra::PcodeInjectLibrary.

|
inlinevirtual |
Retrieve a reusable context object for this library.
The object returned by this method gets passed to the payload inject() method. The clear() method must be called between uses.
Implements ghidra::PcodeInjectLibrary.
|
virtual |
Manually add a call-fixup payload given a compilable snippet of p-code source.
The snippet is compiled immediately to produce the payload.
name | is the formal name of the new payload |
snippetstring | is the compilable snippet of p-code source |
Implements ghidra::PcodeInjectLibrary.
|
virtual |
Manually add a callother-fixup payload given a compilable snippet of p-code source.
The snippet is compiled immediately to produce the payload. Symbol names for input and output parameters must be provided to the compiler.
name | is the formal name of the new payload |
outname | is the name of the output symbol |
inname | is the ordered list of input symbol names |
snippet | is the compilable snippet of p-code source |
Implements ghidra::PcodeInjectLibrary.
|
privatevirtual |
Finalize a payload within the library, once the payload is initialized.
This provides the derived class the opportunity to add the payload name to the symbol tables or do anything else it needs to once the InjectPayload object has been fully initialized.
injectid | is the id of the InjectPayload to finalize |
