This series of patches arise from discovering that: ipvsadm --start-daemon backup --mcast-group IPv6_address ... would always fail.
The first patch resolves the problem. The second and third patches are optimizations that were noticed while investigating the original problem. The fourth patch adds a lock which appears to have been omitted, and the final patch adds the recently added sync daemon multicast parameters to the log messages that are written when the sync daemons start. v2 fixes a compile error in a debug message identified by kbuild test robot. Now compiles with CONFIG_IP_VS_DEBUG enabled. Patch 2/5 is modified to correct the problem, and patch 3/5 is modifed to apply with the modified patch 2/5. v3 incorporates changes suggested by Julian Anastasov. Patch 1 now sets 'sock->sk->sk_bound_dev_if = ifindex' rather than setting sin6_scope_id. Also remove the locks since unnecessary. Patch 3 shortens the logged message in order not to exceed 80-char limit. Patch 4 Removed, the locks aren't necessary Patch 5 No longer changes indentation of existing pr_info. Also removes <> around commit IDs in commit description. Patches 1, 2, 3, 5 are updated to resolve coding style warnings, and all pass with 0 errors, warnings and checks. Patch 5 now becomes patch 4. The changes have all been tested and work as expected.
