Merge branch 'for-3.5' of git://linux-nfs.org/~bfields/linux

2012-06-01T15:32:58Z

Pull the rest of the nfsd commits from Bruce Fields: "... and then I cherry-picked the remainder of the patches from the head of my previous branch" This is the rest of the original nfsd branch, rebased without the delegation stuff that I thought really needed to be redone. I don't like rebasing things like this in general, but in this situation this was the lesser of two evils. * 'for-3.5' of git://linux-nfs.org/~bfields/linux: (50 commits) nfsd4: fix, consolidate client_has_state nfsd4: don't remove rebooted client record until confirmation nfsd4: remove some dprintk's and a comment nfsd4: return "real" sequence id in confirmed case nfsd4: fix exchange_id to return confirm flag nfsd4: clarify that renewing expired client is a bug nfsd4: simpler ordering of setclientid_confirm checks nfsd4: setclientid: remove pointless assignment nfsd4: fix error return in non-matching-creds case nfsd4: fix setclientid_confirm same_cred check nfsd4: merge 3 setclientid cases to 2 nfsd4: pull out common code from setclientid cases nfsd4: merge last two setclientid cases nfsd4: setclientid/confirm comment cleanup nfsd4: setclientid remove unnecessary terms from a logical expression nfsd4: move rq_flavor into svc_cred nfsd4: stricter cred comparison for setclientid/exchange_id nfsd4: move principal name into svc_cred nfsd4: allow removing clients not holding state nfsd4: rearrange exchange_id logic to simplify ...

LockD: service start function introduced

2012-06-01T00:29:44Z

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: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields

LockD: move global usage counter manipulation from error path

LockD: service creation function introduced

2012-06-01T00:29:42Z

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: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields

LockD: use existing per-net data function on service creation

2012-06-01T00:29:42Z

This patch also replaces svc_rpcb_setup() with svc_bind(). Signed-off-by: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields

SUNRPC: move per-net operations from svc_destroy()

2012-06-01T00:29:40Z

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.

SUNRPC: new svc_bind() routine introduced

2012-06-01T00:29:39Z

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: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields
