nfs/nfsd/sunrpc: enforce transport requirements for NFSv4

2017-02-24T22:03:34+00:00

NFSv4 requires a transport "that is specified to avoid network congestion" (RFC 7530, section 3.1, paragraph 2). In practical terms, that means that you should not run NFSv4 over UDP. The server has never enforced that requirement, however. This patchset fixes this by adding a new flag to the svc_version that states that it has these transport requirements. With that, we can check that the transport has XPT_CONG_CTRL set before processing an RPC. If it doesn't we reject it with RPC_PROG_MISMATCH. Signed-off-by: Jeff Layton Signed-off-by: J.

sunrpc: turn bitfield flags in svc_version into bools

2017-02-24T20:50:08+00:00

It's just simpler to read this way, IMO. Also, no need to explicitly set vs_hidden to false in the nfsacl ones. Signed-off-by: Jeff Layton Signed-off-by: J. Bruce Fields

SUNRPC: Add a server side per-connection limit

2016-07-13T19:53:48+00:00

Allow the user to limit the number of requests serviced through a single connection, to help prevent faster clients from starving slower clients. Signed-off-by: Trond Myklebust Signed-off-by: J. Bruce Fields

mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage

2016-04-04T17:41:08+00:00

Mostly direct substitution with occasional adjustment or removing outdated comments. Signed-off-by: Kirill A. Shutemov Acked-by: Michal Hocko Signed-off-by: Linus Torvalds

nfsd/sunrpc: factor svc_rqst allocation and freeing from sv_nrthreads refcounting

2015-08-10T20:05:44+00:00

In later patches, we'll want to be able to allocate and free svc_rqst structures without monkeying with the serv->sv_nrthreads refcount. Factor those pieces out of their respective functions. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: move pool_mode definitions into svc.h

2015-08-10T20:05:43+00:00

In later patches, we're going to need to allow code external to svc.c to figure out what pool_mode is in use. Move these definitions into svc.h to prepare for that. Also, make the svc_pool_map object available and exported so that other modules can peek in there to get insight into what pool mode is in use. Likewise, export svc_pool_map_get/put function to make it safe to do so. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: abstract out svc_set_num_threads to sv_ops

2015-08-10T20:05:43+00:00

Add an operation that will do setup of the service. In the case of a classic thread-based service that means starting up threads. In the case of a workqueue-based service, the setup will do something different. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: turn enqueueing a svc_xprt into a svc_serv operation

2015-08-10T20:05:42+00:00

For now, all services use svc_xprt_do_enqueue, but once we add workqueue-based service support, we'll need to do something different. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: move sv_module parm into sv_ops

2015-08-10T20:05:41+00:00

...not technically an operation, but it's more convenient and cleaner to pass the module pointer in this struct. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields

nfsd/sunrpc: move sv_function into sv_ops

2015-08-10T20:05:41+00:00

Since we now have a container for holding svc_serv operations, move the sv_function into it as well. Signed-off-by: Shirley Ma Acked-by: Jeff Layton Tested-by: Shirley Ma Signed-off-by: J. Bruce Fields
