Subject: [PATCH 0/2] HID: bpf: add one ssize_t check detected by Sashiko
Date: Tue, 15 Sep 2026 17:46:56 +0200 [thread overview]
Message-ID: <20260915-wip-bpf-signed_size-v1-0-6bc8f3d09f5b@kernel.org> (raw)
Sashiko detected an existing issue in hid_bpf_hw_request:
if the transport layer returns an error code, hid_bpf_hw_request
returns success, which can confuse the caller.
Add the actual fix and a selftest to ensure this gets properly passed
around.
