-----Original Message----- From: Anders Roxell
When running tcp_fastopen_backup_key.sh the following issue was seen in a busybox environment. ./tcp_fastopen_backup_key.sh: line 33: [: -ne: unary operator expected
Shellcheck showed the following issue. $ shellcheck tools/testing/selftests/net/tcp_fastopen_backup_key.sh
In tools/testing/selftests/net/tcp_fastopen_backup_key.sh line 33: if [ $val -ne 0 ]; then ^-- SC2086: Double quote to prevent globbing and word splitting.
Rework to add double quotes around the variable 'val' that shellcheck recommends.

Did you test this in the failing environment?
With a busybox shell, I get: $ [ "" -ne 0 ] sh: bad number
You might need to explicitly check for empty string here, or switch to a string comparison instead: if [ "$val" != 0 ]; then
