Highlights include: Stable fixes: - Add validation of the UDP retrans parameter to prevent shift out-of-bounds - Don't discard pNFS layout segments that are marked for return Bugfixes: - Fix a NULL dereference crash in xprt_complete_bc_request() when the NFSv4.1 server misbehaves. - Fix the handling of NFS READDIR cookie verifiers - Sundry fixes to ensure attribute revalidation works correctly when the server does not return post-op attributes. - nfs4_bitmask_adjust() must not change the server global bitmasks - Fix major timeout handling in the RPC code. - NFSv4.2 fallocate() fixes. - Fix the NFSv4.2 SEEK_HOLE/SEEK_DATA end-of-file handling - Copy offload attribute revalidation fixes - Fix an incorrect filehandle size check in the pNFS flexfiles driver - Fix several RDMA transport setup/teardown races - Fix several RDMA queue wrapping issues - Fix a misplaced memory read barrier in sunrpc's call_decode() Features: - Micro optimisation of the TCP transmission queue using TCP_CORK - statx() performance improvements by further splitting up the tracking of invalid cached file metadata. - Support the NFSv4.2 "change_attr_type" attribute and use it to optimise handling of change attribute updates. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEESQctxSBg8JpV8KqEZwvnipYKAPIFAmCVLooACgkQZwvnipYK APJB5BAAtIJyhx40ooMBzcucDmXd1qovlKsb8ZlvnSI6c7wvHhFPNk9z4zwThnjL FpVYzJzK6XzAQY/PtgbrPwnSUmW925ngPWYR/hiYe+OGPBnYV+tXP8izCyEkNgMg 45goDOxojGWl7AGTuAJiKcDSdH9PyIrbvt28iwcNSGjslasGSbAoL/836l4OIGr1 Ymxs/NDML11dPco8GIKLGtHd8leFGleDx089VeNsgud8MdaFErp16O5Iz8DdzRKd W1l2zDMb05j8eDZIfy3w3FyrLkDXA+KgLSADiC8TcpxoadPaQJMeCvoIq8oqVndn bZBoxduXdLgf54Aec0WnNKFAOyc7pGvZoSNmFouT7EGV73g+g1LQ+ZbEE1bb8fCQ XHqCVaBt2+47NiTUgdxjXlZRfcn8fYKx0tVxfG3mQVMXUAWfsjmMyQMNgijDRJI2 8Wz3lZMRGMILbR9j4QpP1biVy/2zGNWG/TB5ZZyZMSY4uT+aOpzlqdknb4UsRaSp f7MfmB7xEWpS4DJr9RIBrJ/hIdnMu1mNInxDPFo5Kl5HNp4TaPm2dPir2ZD2wMZI daURTX7giUhpE15ZebQDBqWD+mTR0bVDqLLeo131JRmMfMEHugNrr49xe+NkBu/R QWnFzgkGdQsOeiKRRwEUuhsi74JspqfwzdZzHqcRM5WuXVvBLcA= =h01b -----END PGP SIGNATURE----- Merge tag 'nfs-for-5.13-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs Pull NFS client updates from Trond Myklebust: "Highlights include: Stable fixes: - Add validation of the UDP retrans parameter to prevent shift out-of-bounds - Don't discard pNFS layout segments that are marked for return Bugfixes: - Fix a NULL dereference crash in xprt_complete_bc_request() when the NFSv4.1 server misbehaves. - Fix the handling of NFS READDIR cookie verifiers - Sundry fixes to ensure attribute revalidation works correctly when the server does not return post-op attributes. - nfs4_bitmask_adjust() must not change the server global bitmasks - Fix major timeout handling in the RPC code. - NFSv4.2 fallocate() fixes. - Fix the NFSv4.2 SEEK_HOLE/SEEK_DATA end-of-file handling - Copy offload attribute revalidation fixes - Fix an incorrect filehandle size check in the pNFS flexfiles driver - Fix several RDMA transport setup/teardown races - Fix several RDMA queue wrapping issues - Fix a misplaced memory read barrier in sunrpc's call_decode() Features: - Micro optimisation of the TCP transmission queue using TCP_CORK - statx() performance improvements by further splitting up the tracking of invalid cached file metadata. - Support the NFSv4.2 'change_attr_type' attribute and use it to optimise handling of change attribute updates" * tag 'nfs-for-5.13-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (85 commits) xprtrdma: Fix a NULL dereference in frwr_unmap_sync() sunrpc: Fix misplaced barrier in call_decode NFSv4.2: Remove ifdef CONFIG_NFSD from NFSv4.2 client SSC code. xprtrdma: Move fr_mr field to struct rpcrdma_mr xprtrdma: Move the Work Request union to struct rpcrdma_mr xprtrdma: Move fr_linv_done field to struct rpcrdma_mr xprtrdma: Move cqe to struct rpcrdma_mr xprtrdma: Move fr_cid to struct rpcrdma_mr xprtrdma: Remove the RPC/RDMA QP event handler xprtrdma: Don't display r_xprt memory addresses in tracepoints xprtrdma: Add an rpcrdma_mr_completion_class xprtrdma: Add tracepoints showing FastReg WRs and remote invalidation xprtrdma: Avoid Send Queue wrapping xprtrdma: Do not wake RPC consumer on a failed LocalInv xprtrdma: Do not recycle MR after FastReg/LocalInv flushes xprtrdma: Clarify use of barrier in frwr_wc_localinv_done() xprtrdma: Rename frwr_release_mr() xprtrdma: rpcrdma_mr_pop() already does list_del_init() xprtrdma: Delete rpcrdma_recv_buffer_put() xprtrdma: Fix cwnd update ordering ...

Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
|
|
never became an official part of the NFS version 3 protocol.
|
|
This protocol extension allows applications on NFS clients to
|
|
manipulate POSIX Access Control Lists on files residing on NFS
|
|
servers. NFS servers enforce POSIX ACLs on local files whether
|
|
this protocol is available or not.

This option enables support in your system's NFS server for the

NFSv3 ACL protocol extension allowing NFS clients to manipulate

POSIX ACLs on files exported by your system's NFS server. NFS
|
|
clients which support the Solaris NFSv3 ACL protocol can then
|
|
access and modify ACLs on your NFS server.
|
|
|

To store ACLs on your NFS server, you also need to enable ACL-

related CONFIG options for your local file systems of choice.
