Plugin for Ghidra to assist reversing Golang binaries

gotools's Issues

Doesn't work with Ghidra 9.1

Hi! This extension seems extremely useful but I cannot install it

Step

Start Ghidra, File > Install Extensions, check the box next to gotools

cannot be completed because extension is in red

Is it possible to make it compatible with 9.1 version?

Add better instructions to install plugin

Should be clear where to go to download a version, put it into the right directory and maybe add build instructions.

Errors creating symbol names on import of binary

Error creating symbol: type.struct {} - Symbol name contains invalid characters: type.struct {}
Error creating symbol: go.(*struct { sync.Mutex; reflect.m sync.Map }).Unlock - Symbol name contains invalid characters: go.(*struct { sync.Mutex; reflect.m sync.Map }).Unlock

Set no_return on certain functions

• runtime.panicindex();

Compatibility with ghidra 10

Describe the bug

Target os: Linux
Ghidra version: 10.0.4

gotools needs to be updated for compatibility with the debugger in the newest version of Ghidra

Describe the bug
The newest version of Ghidra, 10.0.1, operates with a debugger. Ghidra fails to update registers upon state change with the current version of gotools.

Go version: go1.16.6
Target os: Linux
Ghidra version: 10.0.1

To Reproduce
Steps to reproduce the behavior:

1. Unzip ghidra_9.1.2_PUBLIC_20200521_gotools.zip
2. Update version number to 10.0.1 in extension.properties
3. Re-zip
4. Move zip file to $GHIDRA_DIR/Extensions/Ghidra
5. Open Ghidra and install extension
6. Load a Go binary into debugger
7. Debug locally in GDB in VM
8. Set breakpoint anywhere
9. Click Resume
10. The error "Trouble updating registers on state change" appears in Debug Console

Minimal source to reproduce

//none

Expected behavior
When I run the Go binary, I expect the register values to populate in the Registers tab, accessible when I click "Display Decompiler". Instead, no register updates, and each remain set to 0.

Additional context
N/A

Support for other popular platforms

Would it be possible to support Go binaries for other common GOOS / GOARCH combinations?

• darwin/amd64
• darwin/arm64
• linux/386
• linux/amd64
• linux/arm
• linux/arm64
• windows/386
• windows/amd64
• windows/arm

I'd be happy to help add support for other Go binaries.

How complete is the current linux amd64 implementation for this project?

No assignment of return value

Describe the bug

Ghidra does not use the the return value of a function

Go version: 1.12
Target os: Linux
Ghidra version: 9.0.4

To Reproduce

1. Load binary (testdata functions.go)
2. Analyze binary
3. see that main.main does not assign the return values

Minimal source to reproduce
