I've been keeping notes at https://wiki.linux-nfs.org/wiki/index.php/NFS_re-export Remaining issues include reboot recovery, filehandle size limits, and an unidentified crash in the nfsd file locking code. --b. > 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.

Hi Linus- Seasons greetings. tl;dr: The following changes since commit b65054597872ce3aefbc6a666385eabdf9e288da: Linux 5.10-rc6 (2020-11-29 15:50:50 -0800) are available in the Git repository at: git://git.linux-nfs.org/projects/cel/cel-2.6.git tags/nfsd-5.11 for you to fetch changes up to 716a8bc7f706eeef80ab42c99d9f210eda845c81: nfsd: Record NFSv4 pre/post-op attributes as non-atomic (2020-12-09 09:39:38 -0500) ---------------------------------------------------------------- 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! ---------------------------------------------------------------- Alex Shi (1): nfsd/nfs3: remove unused macro nfsd3_fhandleres Cheng Lin (1):

Trond Myklebust (4): exportfs: Add a function to return the raw output from fh_to_dentry() nfsd: Fix up nfsd to ensure that timeout errors don't result in ESTALE nfsd: Set PF_LOCAL_THROTTLE on local filesystems only nfsd: Record NFSv4 pre/post-op attributes as non-atomic kazuo ito (1): nfsd: Fix message level for normal termination Documentation/filesystems/nfs/exporting.rst | 52 ++ fs/exportfs/expfs.c | 32 +- fs/nfs/blocklayout/blocklayout.c | 2 +- fs/nfs/blocklayout/dev.c | 2 +- fs/nfs/dir.c | 2 +- fs/nfs/export.c | 3 + fs/nfs/filelayout/filelayout.c | 2 +- fs/nfs/filelayout/filelayoutdev.c | 2 +- fs/nfs/flexfilelayout/flexfilelayout.c | 2 +- fs/nfs/flexfilelayout/flexfilelayoutdev.c | 2 +- fs/nfs/nfs42xdr.c | 2 +- fs/nfs/nfs4xdr.c | 6 +- fs/nfs_common/grace.c | 6 +- fs/nfsd/export.c | 6 + fs/nfsd/filecache.c | 1 + fs/nfsd/nfs2acl.c | 21 +- fs/nfsd/nfs3acl.c | 8 +- fs/nfsd/nfs3proc.c | 11 +- fs/nfsd/nfs3xdr.c | 40 +- fs/nfsd/nfs4proc.c | 35 +- fs/nfsd/nfs4state.c | 3 +- fs/nfsd/nfs4xdr.c | 2665 +++++++++++++++++++++++++++++++++++++++++++++++-------------------------------------------- fs/nfsd/nfsd.h | 9 +- fs/nfsd/nfsfh.c | 34 +- fs/nfsd/nfsfh.h | 22 +- fs/nfsd/nfsproc.c | 25 +- fs/nfsd/nfssvc.c | 50 +- fs/nfsd/nfsxdr.c | 16 +- fs/nfsd/trace.c | 1 + fs/nfsd/trace.h | 176 +++++- fs/nfsd/vfs.c | 29 +- fs/nfsd/xdr.h | 2 - fs/nfsd/xdr3.h | 2 - fs/nfsd/xdr4.h | 43 +- include/linux/exportfs.h | 13 + include/linux/iversion.h | 13 + include/linux/nfs4.h | 8 - include/linux/sunrpc/svc.h | 22 +- include/linux/sunrpc/svc_rdma.h | 36 +- include/linux/sunrpc/svc_rdma_pcl.h | 128 +++++ include/linux/sunrpc/svc_xprt.h | 4 +- include/linux/sunrpc/xdr.h | 91 +++- include/trace/events/rpcrdma.h | 171 +++--- include/trace/events/sunrpc.h | 24 - net/sunrpc/auth_gss/gss_rpc_upcall.c | 15 +- net/sunrpc/auth_gss/gss_rpc_xdr.c | 3 +- net/sunrpc/cache.c | 41 +- net/sunrpc/svc.c | 16 +- net/sunrpc/svc_xprt.c | 4 +- net/sunrpc/svcsock.c | 8 +- net/sunrpc/xdr.c | 78 ++- net/sunrpc/xprtrdma/Makefile | 2 +- net/sunrpc/xprtrdma/svc_rdma_backchannel.c | 14 +- net/sunrpc/xprtrdma/svc_rdma_pcl.c | 306 +++++++++++ net/sunrpc/xprtrdma/svc_rdma_recvfrom.c | 316 ++++++----- net/sunrpc/xprtrdma/svc_rdma_rw.c | 608 +++++++++++++++------ net/sunrpc/xprtrdma/svc_rdma_sendto.c | 560 ++++++++++--------- net/sunrpc/xprtrdma/svc_rdma_transport.c | 2 +- 58 files changed, 3536 insertions(+), 2261 deletions(-) create mode 100644 include/linux/sunrpc/svc_rdma_pcl.h create mode 100644 net/sunrpc/xprtrdma/svc_rdma_pcl.c -- Chuck Lever
