Pull more nfsd updates from Bruce Fields: "Apologies for the previous request, which omitted the top 8 commits from my for-next branch (including the SCSI layout commits). Thanks to Trond for spotting my error!" This actually includes the new layout types, so here's that part of the pull message repeated: "Support for a new pnfs layout type from Christoph Hellwig. The new layout type is a variant of the block layout which uses SCSI features to offer improved fencing and device identification. Note this pull request also includes the client side of SCSI layout, with Trond's permission" * tag 'nfsd-4.6-1' of git://linux-nfs.org/~bfields/linux: nfsd: use short read as well as i_size to set eof nfsd: better layoutupdate bounds-checking nfsd: block and scsi layout drivers need to depend on CONFIG_BLOCK nfsd: add SCSI layout support nfsd: move some blocklayout code nfsd: add a new config option for the block layout driver nfs/blocklayout: add SCSI layout support nfs4.h: add SCSI layout definitions

nfsd: add SCSI layout support

2016-03-18T15:42:53+00:00

This is a simple extension to the block layout driver to use SCSI persistent reservations for access control and fencing, as well as SCSI VPD pages for device identification. For this we need to pass the nfs4_client to the proc_getdeviceinfo method to generate the reservation key, and add a new fence_client method to allow for fence actions in the layout driver.

ipconfig: send Client-identifier in DHCP requests

2015-10-19T02:23:52+00:00

A dhcp server may provide parameters to a client from a pool of IP addresses and using a shared rootfs, or provide a specific set of parameters for a specific client, usually using the MAC address to identify each client individually. The dhcp protocol also specifies a client-id field which can be used to determine the correct parameters to supply when no MAC address is available. There is currently no way to tell the kernel to supply a specific client-id, only the userspace dhcp clients support this feature, but this can not be used when the network is needed before userspace is available such as when the root filesystem is on NFS. This patch is to be able to do something like "ip=dhcp,client_id_type, client_id_value", as a kernel parameter to enable the kernel to identify itself to the server.

Merge branch 'for-3.20' of git://linux-nfs.org/~bfields/linux

2015-02-12T18:39:41+00:00

Pull nfsd updates from Bruce Fields: "The main change is the pNFS block server support from Christoph, which allows an NFS client connected to shared disk to do block IO to the shared disk in place of NFS reads and writes. This also requires xfs patches, which should arrive soon through the xfs tree, barring unexpected problems. Support for other filesystems is also possible if there's interest. Thanks also to Chuck Lever for continuing work to get NFS/RDMA into shape" * 'for-3.20' of git://linux-nfs.org/~bfields/linux: (32 commits) nfsd: default NFSv4.2 to on nfsd: pNFS block layout driver exportfs: add methods for block layout exports nfsd: add trace events nfsd: update documentation for pNFS support nfsd: implement pNFS layout recalls nfsd: implement pNFS operations nfsd: make find_any_file available outside nfs4state.c nfsd: make find/get/put file available outside nfs4state.c nfsd: make lookup/alloc/unhash_stid available outside nfs4state.c nfsd: add fh_fsid_match helper nfsd: move nfsd_fh_match to nfsfh.h fs: add FL_LAYOUT lease type fs: track fl_owner for leases nfs: add LAYOUT_TYPE_MAX enum value nfsd: factor out a helper to decode nfstime4 values sunrpc/lockd: fix references to the BKL nfsd: fix year-2038 nfs4 state problem svcrdma: Handle additional inline content svcrdma: Move read list XDR round-up logic ...

nfsd: pNFS block layout driver

2015-02-05T13:35:18+00:00

Add a small shim between core nfsd and filesystems to translate the somewhat cumbersome pNFS data structures and semantics to something more palatable for Linux filesystems. Thanks to Rick McNeal for the old prototype pNFS blocklayout server code, which gave a lot of inspiration to this version even if no code is left from it. Signed-off-by: Christoph Hellwig
