  "message": "ospf6d: Fix loss of hello\u0027s on interface\n\nSYMPTOM:\n\nWith quagga running on Linux, \u0027ifdown \u003cif-name\u003e\u0027 followed by \u0027ifup \u003cifname\u003e\ncan cause OSPFv3 to not receive Hello packets on the interface.\n\nISSUE:\n\nOperating System\u0027s interface IPv6 readiness may not be guaranteed at the\ntime of interface-up event. Thats because the ipv6 components in an OS may\nalso be listening to the same interface-up event that (in this case) is\nrelayed to OSPFv3.\n\nIn this failure case, setsockopt with option IPV6_JOIN_GROUP on the interface\nreturned EINVAL.\n\nError logs -\nOSPF6: Zebra Interface state change: swp1 index 3 flags 11043 metric 1 mtu 1500\nOSPF6: Interface Event swp1: [InterfaceUp]\nOSPF6: Network: setsockopt (20) on ifindex 3 failed: Invalid argument\n\nFIX:\n\nTo take care of this possible race condition, any address-family related\nsetting should be retried. Given it\u0027s a rare condition and window of this\nrace should be short, the patch adds a limited retry mechanism for the\nIPV6 membership setting on the socket.\n\nSigned-off-by: Vipin Kumar \u003cvipin@cumulusnetworks.com\u003e\nReviewed-by: Dinesh Dutt \u003cddutt@cumulusnetworks.com\u003e\n             Satish Ashok \u003csashok@cumulusnetworks.com\u003e\n",
