selftests: openvswitch: Use bash as interpreter
[ Upstream commit e2b447c9a1bba718f9c07513a1e8958209e862a1 ]
openvswitch.sh makes use of substitutions of the form ${ns:0:1}, to
obtain the first character of $ns. Empirically, this is works with bash
but not dash. When run with dash these evaluate to an empty string and
printing an error to stdout.
# dash -c 'ns=client; echo "${ns:0:1}"' 2>error
# cat error
dash: 1: Bad substitution
# bash -c 'ns=client; echo "${ns:0:1}"' 2>error
c
# cat error
This leads to tests that neither pass nor fail.
F.e.
TEST: arp_ping [START]
adding sandbox 'test_arp_ping'
Adding DP/Bridge IF: sbx:test_arp_ping dp:arpping {, , }
create namespaces
./openvswitch.sh: 282: eval: Bad substitution
TEST: ct_connect_v4 [START]
adding sandbox 'test_ct_connect_v4'
Adding DP/Bridge IF: sbx:test_ct_connect_v4 dp:ct4 {, , }
./openvswitch.sh: 322: eval: Bad substitution
create namespaces
Resolve this by making openvswitch.sh a bash script.
