Given an invalid 'rate' command e.g. 'rate 0' the return value is '1', leading to the following misleading output: - the good case $ echo "rate 100" > /proc/net/pktgen/lo\@0 $ grep "Result:" /proc/net/pktgen/lo\@0 Result: OK: rate=100 - the bad case (before the patch) $ echo "rate 0" > /proc/net/pktgen/lo\@0" -bash: echo: write error: Invalid argument $ grep "Result:" /proc/net/pktgen/lo\@0 Result: No such parameter "ate" - with patch applied $ echo "rate 0" > /proc/net/pktgen/lo\@0 -bash: echo: write error: Invalid argument $ grep "Result:" /proc/net/pktgen/lo\@0 Result: Idle Signed-off-by: Peter Seiderer <ps.report@gmx.net> --- Changes v1 -> v2: - new patch --- net/core/pktgen.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
