From e2baf9cc374d5374e28702cb40e78551e82dd183 Mon Sep 17 00:00:00 2001 From: Tushar Vyavahare Date: Tue, 28 Jul 2026 11:50:36 +0000 Subject: [PATCH] selftests/xsk: Decouple xskxceiver and xdp apps from test_progs objects 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.
