From d95ba15b97847f4ae520db83bd98b61d50fb3068 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Thu, 23 May 2024 14:49:57 +0800 Subject: [PATCH] selftests/bpf: Fix tx_prog_fd values in test_sockmap The values of tx_prog_fd in run_options() should not be 0, so set it as -1 in else branch, and test it using "if (tx_prog_fd > 0)" condition, not "if (tx_prog_fd)" or "if (tx_prog_fd >= 0)".
