charset=UTF-8 Content-Transfer-Encoding: 8bit with_stress.sh invokes the requested command through unquoted $*. This subjects the arguments to word splitting and pathname expansion: arguments containing whitespace are split, empty arguments disappear, and literal wildcard characters can expand to filenames. Invoke the command through "$@" so that the command name and each argument are passed as supplied by the caller. Fixes: 1a99fcc035fb ("selftests: cgroup: Run test_core under interfering stress") Assisted-by: LLM Signed-off-by: Ren Tamura --- Validation (2026-09-24, mainline 62f4c998b297): ran both versions of the actual wrapper under Bash on Linux with a fixture mount listing and no stress workers. The argument boundaries, empty argument and literal wildcard are preserved after the change: Input: ["two words", "", "*.txt"] Before: ["two", "words", "match.txt"] After: ["two words", "", "*.txt"] Ordinary arguments and the child command's nonzero exit status are unchanged. LLM assistance: finding small cgroup fixes, drafting code and commit messages, and preparing validation. tools/testing/selftests/cgroup/with_stress.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/cgroup/with_stress.sh b/tools/testing/selftests/cgroup/with_stress.sh index e28c35008f5b7a0f66654b10d8fccf4678120f6e..a95fb387464460ba24775a3e947a91875b743bc9 100755 --- a/tools/testing/selftests/cgroup/with_stress.sh +++ b/tools/testing/selftests/cgroup/with_stress.sh @@ -87,7 +87,7 @@ time=0 start=$(date +%s) while [ $time -lt $duration ] ; do - $* + "$@" rc=$?
