NLM: Remove "proto" argument from lockd_up()

2008-10-04T21:12:27Z

Clean up: Now that lockd_up() starts listeners for both transports, the "proto" argument is no longer needed. Signed-off-by: Chuck Lever Cc: Neil Brown Signed-off-by: J. Bruce Fields

lockd: Remove unused fields in the nlm_reboot structure

2008-10-03T21:02:35Z

The nlm_reboot structure is used to store information provided by the NSM_NOTIFY procedure. This procedure is not specified by the NLM or NSM protocols, other than to say that the procedure can be used to transmit information private to a particular NLM/NSM implementation. For Linux, the callback arguments include the name of the monitored host, the new NSM state of the host, and a 16-byte private opaque. As a clean up, remove the unused fields and the server-side XDR logic that decodes them. Signed-off-by: Chuck Lever Signed-off-by: J. Bruce Fields

lockd: Add helper to sanity check incoming NOTIFY requests

2008-10-03T21:02:35Z

lockd accepts SM_NOTIFY calls only from a privileged process on the local system. If lockd uses an AF_INET6 listener, the sender's address (ie the local rpc.statd) will be the IPv6 loopback address, not the IPv4 loopback address. Make sure the privilege test in nlmsvc_proc_sm_notify() and nlm4svc_proc_sm_notify() works for both AF_INET and AF_INET6 family addresses by refactoring the test into a helper and adding support for IPv6 addresses.

lockd: change nlmclnt_grant() to take a "struct sockaddr *"

2008-10-03T21:02:35Z

Adjust the signature and callers of nlmclnt_grant() to pass a "struct sockaddr *" instead of a "struct sockaddr_in *" in order to support IPv6 addresses. Signed-off-by: Chuck Lever Signed-off-by: J. Bruce Fields

lockd: Adjust nlmsvc_lookup_host() to accomodate AF_INET6 addresses

2008-10-03T21:02:35Z

Fix up nlmsvc_lookup_host() to pass AF_INET6 source addresses to nlm_lookup_host(). Signed-off-by: Chuck Lever Signed-off-by: J. Bruce Fields

lockd: Adjust nlmclnt_lookup_host() signature to accomodate non-AF_INET

2008-10-03T21:02:34Z

Pass a struct sockaddr * and a length to nlmclnt_lookup_host() to accomodate non-AF_INET family addresses. As a side benefit, eliminate the hostname_len argument, as the hostname is always NUL-terminated. Signed-off-by: Chuck Lever Signed-off-by: J. Bruce Fields

lockd: move grace period checks to common code

2008-10-03T20:19:19Z

Do all the grace period checks in svclock.c. This simplifies the code a bit, and will ease some later changes. Signed-off-by: J. Bruce Fields

nfsd: common grace period control

2008-10-03T20:19:02Z

Rewrite grace period code to unify management of grace period across lockd and nfsd. The current code has lockd and nfsd cooperate to compute a grace period which is satisfactory to them both, and then individually enforce it. This creates a slight race condition, since the enforcement is not coordinated. It's also more complicated than necessary. Here instead we have lockd and nfsd each inform common code when they enter the grace period, and when they're ready to leave the grace period, and allow normal locking only after both of them are ready to leave. We also expect the locks_start_grace()/locks_end_grace() interface here to be simpler to build on for future cluster/high-availability work, which may require (for example) putting individual filesystems into grace, or enforcing grace periods across multiple cluster nodes.

lockd: Teach nlm_cmp_addr() to support AF_INET6 addresses

2008-09-29T22:13:39Z

Update the nlm_cmp_addr() helper to support AF_INET6 as well as AF_INET addresses. New version takes two "struct sockaddr *" arguments instead of "struct sockaddr_in *" arguments. Signed-off-by: Chuck Lever Signed-off-by: J. Bruce Fields

NSM: Use sockaddr_storage for sm_addr field

2008-09-29T22:13:39Z

To store larger addresses in the nsm_handle structure, make sm_addr a sockaddr_storage. Signed-off-by: Chuck Lever Signed-off-by: J. Bruce Fields
