Currently session draining only drains the fore channel. The back channel processing must also be drained. Use the back channel highest_slot_used to indicate that a callback is being processed by the callback thread. Move the session complete to be per channel. When the session is draininig, wait for any current back channel processing to complete and stop all new back channel processing by returning NFS4ERR_DELAY to the back channel client. Drain the back channel, then the fore channel. Signed-off-by: NAndy Adamson <andros@netapp.com> Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Fixes a bug where the nfs_client could be freed during callback processing. Refactor nfs_find_client to use minorversion specific means to locate the correct nfs_client structure. In the NFS layer, V4.0 clients are found using the callback_ident field in the CB_COMPOUND header. V4.1 clients are found using the sessionID in the CB_SEQUENCE operation which is also compared against the sessionID associated with the back channel thread after a successful CREATE_SESSION. Each of these methods finds the one an only nfs_client associated with the incoming callback request - so nfs_find_client_next is not needed. In the RPC layer, the pg_authenticate call needs to find the nfs_client. For the v4.0 callback service, the callback identifier has not been decoded so a search by address, version, and minorversion is used. The sessionid for the sessions based callback service has (usually) not been set for the pg_authenticate on a CB_NULL call which can be sent prior to the return of a CREATE_SESSION call, so the sessionid associated with the back channel thread is not used to find the client in pg_authenticate for CB_NULL calls. Pass the referenced nfs_client to each CB_COMPOUND operation being proceesed via the new cb_process_state structure. The reference is held across cb_compound processing. Use the new cb_process_state struct to move the NFS4ERR_RETRY_UNCACHED_REP processing from process_op into nfs4_callback_sequence where it belongs.

The sessions based callback service is started prior to the CREATE_SESSION call so that it can handle CB_NULL requests which can be sent before the CREATE_SESSION call returns and the session ID is known.

Note that this patch changes the nfsv4.0 behavior also when CONFIG_NFS_V4_1 is not defined where NFS4ERR_MINOR_VERS_MISMATCH will be returned if the client received a CB_COMPOUND with minorversion != 0. Previously, it would have returned NFS4ERR_OP_ILLEGAL for CB_SEQUENCE. (or if the server is broken and sent OP_CB_GETATTR or OP_CB_RECALL with minorversion!=0, they would have been processed normally.

nfs41_callback_up() initializes the necessary queues and creates the new nfs41_callback_svc thread. This thread executes the callback service which waits for requests to arrive on the svc_serv->sv_cb_list. NFS41_BC_MIN_CALLBACKS is set to 1 because we expect callbacks to not cause substantial latency. The actual processing of the callback will be implemented as a separate patch. There is only one NFSv4.1 callback service. The first caller of nfs4_callback_up() creates the service, subsequent callers increment a reference count on the service. The service is destroyed when the last caller invokes nfs_callback_down(). The transport needs to hold a reference to the callback service in order to invoke it during callback processing. Currently this reference is only obtained when the service is first created. This is incorrect, since subsequent registrations for other transports will leave the xprt->serv pointer uninitialized, leading to an oops when a callback arrives on the "unreferenced" transport. This patch fixes the problem by ensuring that a reference to the service is saved in xprt->serv, either because the service is created by this invocation to nfs4_callback_up() or by a prior invocation.

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 NFSv4 callback 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 the NFS client can try to start a PF_INET6 listener, but it isn't required to be available.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
