From 6bd3ae4fe0b0ea70f26f0b85e39c9c6b01661b4b Mon Sep 17 00:00:00 2001 From: Geoff Adams Date: Tue, 27 Nov 2018 20:40:11 -0800 Subject: T1055: Wait for Duplicate Address Detection on the relevant interface The DHCPv6 client can't start on an interface when DAD is ongoing. There is a workaround in place to wait for DAD to complete, but it only works on eth0! --- scripts/vyatta-dhcpv6-client.pl | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/scripts/vyatta-dhcpv6-client.pl b/scripts/vyatta-dhcpv6-client.pl index c0b4cfeb..64c6840d 100755 --- a/scripts/vyatta-dhcpv6-client.pl +++ b/scripts/vyatta-dhcpv6-client.pl @@ -146,7 +146,7 @@ if (defined($start_flag) || defined ($renew_flag)) { # https://phabricator.vyos.net/T903 for (my $attempt_count = 0; $attempt_count <= 60; $attempt_count++) { # Check for any non-tentative addresses (exit code 0 if any exist, 1 otherwise) - if (system("test -n \"\$(ip -6 -o addr show dev eth0 scope link -tentative)\"") != 0) { + if (system("test -n \"\$(ip -6 -o addr show dev $ifname scope link -tentative)\"") != 0) { # No non-tentative address found, sleep and retry or exit if ($attempt_count == 0) { print "Duplicate address detection incomplete, waiting\n" -- cgit v1.2.3
