According to RFC 3530bis, the only items SETCLIENTID_CONFIRM processing should be concerned with is the clientid, clientid verifier, and principal. The client's IP address is not supposed to be interesting. And, NFS4ERR_CLID_INUSE is meant only for principal mismatches. I triggered this logic with a prototype UCS client -- one that uses the same nfs_client_id4 string for all servers. The client mounted our server via its IPv4, then via its IPv6 address.

This is just a code move, which from my POV makes the code look better. I.e. now on start we have 3 different stages: 1) Service creation. 2) Service per-net data allocation. 3) Service start. Signed-off-by:

This function creates service if it doesn't exist, or increases usage counter if it does, and returns a pointer to it. The usage counter will be droppepd by svc_destroy() later in lockd_up(). Signed-off-by:

There's little point in waiting until after we allocate all of the pages to see if we're going to overrun the array. In the event that this calculation is really off we could end up scribbling over a bunch of memory and make it tougher to debug. Signed-off-by:

The idea is to separate service destruction and per-net operations, because these are two different things and the mix looks ugly. Notes: 1) For NFS server this patch looks ugly (sorry for that). But these place will be rewritten soon during NFSd containerization. 2) LockD per-net counter increase int lockd_up() was moved prior to make_socks() to make lockd_down_net() call safe in case of error.

This new routine is responsible for service registration in a specified network context. The idea is to separate service creation from per-net operations. Note also: since registering service with svc_bind() can fail, the service will be destroyed and during destruction it will try to unregister itself from rpcbind. In this case unregistration has to be skipped. Signed-off-by:

The data in Kerberos gss tokens can be rotated. But we were lazy and rejected any nonzero rotation value. It wasn't necessary for the implementations we were testing against at the time. But it appears that Windows does use a nonzero value here. So, implement rotation to bring ourselves into compliance with the spec and to interoperate with Windows. Signed-off-by: -

The fs_location->hosts list is split on colons, but this doesn't work when IPv6 addresses are used (they contain colons). This patch adds the function nfsd4_encode_components_esc() to allow the caller to specify escape characters when splitting on 'sep'. In order to fix referrals, this patch must be used with the mountd patch that similarly fixes IPv6 [] escaping. Signed-off-by:

This cache will be per-net soon. And it's easier to get the pointer to desired per-net instance only once and then pass it down instead of discovering it in every place were required. Signed-off-by:

v2: dereference of most probably already released nlm_host removed in nlmclnt_done() and reclaimer(). These routines are called from locks reclaimer() kernel thread. This thread works in "init_net" network context and currently relays on persence on lockd thread and it's per-net resources. Thus lockd_up() and lockd_down() can't relay on current network context. So let's pass corrent one into them. Signed-off-by:

These dereferences to global static caches are redundant. They also prevents converting these caches into per-net ones. So this patch is cleanup + precursor of patch set,a which will make them per-net. Signed-off-by:

It's possible that lockd or another lock manager might still be on the list after we call nfsd4_end_grace. If the laundromat thread runs again at that point, then we could end up calling nfsd4_end_grace more than once. That's not only inefficient, but calling nfsd4_recdir_purge_old more than once could be problematic. Fix this by adding a new global "grace_ended" flag and use that to determine whether we've already called nfsd4_grace_end. Signed-off-by:
