From mboxrd@z Thu Jan 1 00:00:00 1970 From: Taeung Song Subject: [PATCH v2] samples/bpf: Fix tc and ip paths in xdp2skb_meta.sh Date: Tue, 10 Jul 2018 02:51:21 +0900 Message-ID: <20180709175121.3355-1-treeze.taeung@gmail.com> Cc: Jesper Dangaard Brouer , netdev@vger.kernel.org, linux-kernel@vger.kernel.org, Taeung Song To: Alexei Starovoitov , Daniel Borkmann Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org The below path error can occur: # ./xdp2skb_meta.sh --dev eth0 --list ./xdp2skb_meta.sh: line 61: /usr/sbin/tc: No such file or directory So just use command names instead of absolute paths of tc and ip. In addition, it allow callers to redefine $TC and $IP paths Fixes: 36e04a2d78d9 ("samples/bpf: xdp2skb_meta shows transferring info from XDP to SKB") Reviewed-by: Jesper Dangaard Brouer Signed-off-by: Taeung Song --- samples/bpf/xdp2skb_meta.sh | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/samples/bpf/xdp2skb_meta.sh b/samples/bpf/xdp2skb_meta.sh index b9c9549c4c27..4bde9d066c46 100755 --- a/samples/bpf/xdp2skb_meta.sh +++ b/samples/bpf/xdp2skb_meta.sh @@ -16,8 +16,8 @@ BPF_FILE=xdp2skb_meta_kern.o DIR=$(dirname $0) -export TC=/usr/sbin/tc -export IP=/usr/sbin/ip +[ -z "$TC" ] && TC=tc +[ -z "$IP" ] && IP=ip function usage() { echo "" @@ -53,7 +53,7 @@ function _call_cmd() { local allow_fail="$2" shift 2 if [[ -n "$VERBOSE" ]]; then - echo "$(basename $cmd) $@" + echo "$cmd $@" fi if [[ -n "$DRYRUN" ]]; then return -- 2.17.1
