Subject: [PATCH net-next] selftests/xsk: decouple xskxceiver and xdp apps from test_progs objects
Date: Sat, 18 Jul 2026 13:44:50 +0000 [thread overview]
Message-ID: <20260718134450.575758-1-tushar.vyavahare@intel.com> (raw)
Build xskxceiver, xdp_hw_metadata, and xdp_features from explicit source
lists instead of reusing helper objects produced by test_progs rules.
Reusing shared objects such as network_helpers.o and xsk.o can pull in
test_progs-only dependency chains and trigger unrelated libarena builds
when invoking a single target.
Keep these standalone binaries self-contained so each target builds only
its own required sources and BPF skeleton dependencies.
