lockd: fix arg parsing for grace_period and timeout.

2012-02-17T23:38:51Z

If you try to set grace_period or timeout via a module parameter to lockd, and do this on a big-endian machine where sizeof(int) != sizeof(unsigned long) it won't work. This number given will be effectively shifted right by the difference in those two sizes. So cast kp->arg properly to get correct result.

Lockd: shutdown NLM hosts in network namespace context

2012-02-15T05:19:48Z

Lockd now managed in network namespace context. And this patch introduces network namespace related NLM hosts shutdown in case of releasing per-net Lockd resources. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

LockD: make NSM network namespace aware

2012-02-15T05:19:48Z

NLM host is network namespace aware now. So NSM have to take it into account. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

LockD: make nlm hosts network namespace aware

2012-02-15T05:19:48Z

This object depends on RPC client, and thus on network namespace. So let's make it's allocation and lookup in network namespace context. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

Lockd: per-net up and down routines introduced

2012-02-15T05:19:47Z

This patch introduces per-net Lockd initialization and destruction routines. The logic is the same as in global Lockd up and down routines. Probably the solution is not the best one. But at least it looks clear. So per-net "up" routine are called only in case of lockd is running already. If per-net resources are not allocated yet, then service is being registered with local portmapper and lockd sockets created. Per-net "down" routine is called on every lockd_down() call in case of global users counter is not zero. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

Lockd: pernet usage counter introduced

2012-02-15T05:19:47Z

Lockd is going to be shared between network namespaces - i.e. going to be able to handle lock requests from different network namespaces. This means, that network namespace related resources have to be allocated not once (like now), but for every network namespace context, from which service is requested to operate. This patch implements Lockd per-net users accounting. New per-net counter is used to determine, when per-net resources have to be freed.

Lockd: create permanent lockd sockets in current network namespace

2012-02-15T05:19:46Z

This patch parametrizes Lockd permanent sockets creation routine by network namespace context. It also replaces hard-coded init_net with current network namespace context in Lockd sockets creation routines. This approach looks safe, because Lockd is created during NFS mount (or NFS server start) and thus socket is required exactly in current network namespace context. But in the same time it means, that Lockd sockets inherits first Lockd requester network namespace. This issue will be fixed in further patches of the series.
