Merge tag 'nfsd-5.11' of git://git.linux-nfs.org/projects/cel/cel-2.6
Pull nfsd updates from Chuck Lever:
"Several substantial changes this time around:
- Previously, exporting an NFS mount via NFSD was considered to be an
unsupported feature. With v5.11, the community has attempted to
make re-exporting a first-class feature of NFSD.
This would enable the Linux in-kernel NFS server to be used as an
intermediate cache for a remotely-located primary NFS server, for
example, even with other NFS server implementations, like a NetApp
filer, as the primary.
- A short series of patches brings support for multiple RPC/RDMA data
chunks per RPC transaction to the Linux NFS server's RPC/RDMA
transport implementation.
This is a part of the RPC/RDMA spec that the other premiere
NFS/RDMA implementation (Solaris) has had for a very long time, and
completes the implementation of RPC/RDMA version 1 in the Linux
kernel's NFS server.
- Long ago, NFSv4 support was introduced to NFSD using a series of C
macros that hid dprintk's and goto's. Over time, the kernel's XDR
implementation has been greatly improved, but these C macros have
remained and become fallow. A series of patches in this pull
request completely replaces those macros with the use of current
kernel XDR infrastructure. Benefits include:
- More robust input sanitization in NFSD's NFSv4 XDR decoders.
- Make it easier to use common kernel library functions that use
XDR stream APIs (for example, GSS-API).
- Align the structure of the source code with the RFCs so it is
easier to learn, verify, and maintain our XDR implementation.
- Removal of more than a hundred hidden dprintk() call sites.
- Removal of some explicit manipulation of pages to help make the
eventual transition to xdr->bvec smoother.
- On top of several related fixes in 5.10-rc, there are a few more
fixes to get the Linux NFSD implementation of NFSv4.2 inter-server
copy up to speed.
And as usual, there is a pinch of seasoning in the form of a
collection of unrelated minor bug fixes and clean-ups.
Many thanks to all who contributed this time around!"
