Support for -toolexec in garble

[we11adam]

Hi,

It appears that garble and OpenTelemetry (or otel) are experiencing compatibility issues due to their interaction with the Go toolchain. I've had a brief discussion with @123liuziming, and it seems the resolution may primarily lie within garble.

We would appreciate any thoughts on how to improve this compatibility.

garble now does not support to use -toolexec manually, can we support this to make two Agent compatible?

Out of curiosity, why would you want to add telemetry instrumentation to an obfuscated binary? Telemetry instrumentation by design will expose more information about what a binary is doing, so it goes directly against the goals of obfuscation in general.

Hi Daniel,

Adding telemetry instrumentation is about automating the bootstrapping of application metrics at a high level, while obfuscating the binary helps prevent reverse engineering of the binary file itself (kind of — I know! :-P).

Best,
