register_handler: calling cage should be the destination grate. by stupendoussuperpowers · Pull Request #979 · Lind-Project/lind-wasm

stupendoussuperpowers · 2026-03-24T06:20:56Z

The current model when we interpose on register_handler is: "If anyone tries to interpose this target_cage, send it to me" and not "If this grate is the target for a register handler on any random cage, send it to me"

This PR fixes that and updates the interpose-register test to be compatible with the expected semantics.

so the interpose test seems to fail with this?

stupendoussuperpowers · 2026-03-25T02:55:26Z

Shouldn't the register_handler interposition have 3 grates?

main grate -> regular grate -> cage

and whenever we try to register_handler with target_grateid = regular grate, it goes to main grate first?

Not sure what the test we currently have is doing.

Not sure what the test we currently have is doing.

The interposing register_handler test case is registering handlers in cage and grate interposes it then send it to 3i. I don't prefer we set the scenarios described here as default..

Could you point me to the case current version causes problems?

stupendoussuperpowers · 2026-03-25T18:28:19Z

Could you point me to the case current version causes problems?

The current model when we interpose on register_handler is: "If anyone tries to interpose this target_cage, send it to me" and not "If this grate is the target for a register handler on any random cage, send it to me"

The current test interposes on the child cage, and then when it registers geteuid on it, we hit the custom handler.

The thing we want to test is that we hit the custom handler if the child grate tries to register something to divert to itself.

The current model when we interpose on register_handler is: "If anyone tries to interpose this target_cage, send it to me" and not "If this grate is the target for a register handler on any random cage, send it to me"

I see this makes sense to me. Could you update the interposing handler test and also comment this on the glibc? Thanks
