From eb16e907781a9da7f272a3e8284c26bc4e4aeb9d Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 18 Mar 2009 20:47:59 -0400 Subject: [PATCH] lockd: Start PF_INET6 listener only if IPv6 support is available Apparently a lot of people need to disable IPv6 completely on their distributor-built systems, which have CONFIG_IPV6_MODULE enabled at build time. They do this by blacklisting the ipv6.ko module. This causes the creation of the lockd service listener to fail if CONFIG_IPV6_MODULE is set, but the module cannot be loaded. Now that the kernel's PF_INET6 RPC listeners are completely separate from PF_INET listeners, we can always start PF_INET. Then lockd can try to start PF_INET6, but it isn't required to be available. Note this has the added benefit that NLM callbacks from AF_INET6 servers will never come from AF_INET remotes. We no longer have to worry about matching mapped IPv4 addresses to AF_INET when comparing addresses. Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust --- Reading git-format-patch failed
