[PATCH 0/2] binder+rust_binder: use current_euid() for transaction sender identity

[Jann Horn]

Based on the discussion on
<https://lore.kernel.org/all/20260212-rust-uid-v1-1-deff4214c766@xxxxxxxxxx/>,
here's a proposed change to binder to stop looking at objective EUIDs.

This removes the last remaining users of Task::euid() (in Rust), and the
only remaining caller to task_euid() is the now-unused Rust wrapper.

(Sidenote: It might be worth considering whether it really makes sense
to have functions like current_euid(), task_euid(), and so on in Rust -
it might be less messy to just expose current_cred() and (if necessary)
get_task_cred(), and then use the `Credential` abstraction around
`struct cred` to access the various UID/GID/... fields.)

(build-tested only.)
