From b4fe9fec51ef48011f11c2da4099f0b530449c92 Mon Sep 17 00:00:00 2001 From: KP Singh Date: Fri, 11 Dec 2020 01:07:11 +0000 Subject: selftests/bpf: Silence ima_setup.sh when not running in verbose mode. Currently, ima_setup.sh spews outputs from commands like mkfs and dd on the terminal without taking into account the verbosity level of the test framework. Update test_progs to set the environment variable SELFTESTS_VERBOSE=1 when a verbose output is requested. This environment variable is then used by ima_setup.sh (and can be used by other similar scripts) to obey the verbosity level of the test harness without needing to re-implement command line options for verbosity. In "silent" mode, the script saves the output to a temporary file, the contents of which are echoed back to stderr when the script encounters an error.
