selftests/net: fix grep checking for fib_nexthop_multiprefix
[ Upstream commit a33e9da3470499e9ff476138f271fb52d6bfe767 ]
When running fib_nexthop_multiprefix test I saw all IPv6 test failed.
e.g.
]# ./fib_nexthop_multiprefix.sh
TEST: IPv4: host 0 to host 1, mtu 1300 [ OK ]
TEST: IPv6: host 0 to host 1, mtu 1300 [FAIL]
With -v it shows
COMMAND: ip netns exec h0 /usr/sbin/ping6 -s 1350 -c5 -w5 2001:db8:101::1
PING 2001:db8:101::1(2001:db8:101::1) 1350 data bytes
From 2001:db8:100::64 icmp_seq=1 Packet too big: mtu=1300
--- 2001:db8:101::1 ping statistics ---
1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms
Route get
2001:db8:101::1 via 2001:db8:100::64 dev eth0 src 2001:db8:100::1 metric 1024 expires 599sec mtu 1300 pref medium
Searching for:
2001:db8:101::1 from :: via 2001:db8:100::64 dev eth0 src 2001:db8:100::1 .* mtu 1300
The reason is when CONFIG_IPV6_SUBTREES is not enabled, rt6_fill_node() will
not put RTA_SRC info. After fix:
]# ./fib_nexthop_multiprefix.sh
TEST: IPv4: host 0 to host 1, mtu 1300 [ OK ]
TEST: IPv6: host 0 to host 1, mtu 1300 [ OK ]
Fixes: 735ab2f65dce ("selftests: Add test with multiple prefixes using single nexthop")
