   8        select NFS_ACL_SUPPORT if NFSD_V2_ACL
   9        help
  10          Choose Y here if you want to allow other computers to access
  11          files residing on this system using Sun's Network File System
  12          protocol.  To compile the NFS server support as a module,
  13          choose M here: the module will be called nfsd.
  14
  15          You may choose to use a user-space NFS server instead, in which
  16          case you can choose N here.
  17
  18          To export local file systems using NFS, you also need to install
  19          user space programs which can be found in the Linux nfs-utils
  20          package, available from http://linux-nfs.org/.  More detail about
  21          the Linux NFS server implementation is available via the
  22          exports(5) man page.
  23
  24          Below you can choose which versions of the NFS protocol are
  25          available to clients mounting the NFS server on this system.
  26          Support for NFS version 2 (RFC 1094) is always available when
  27          CONFIG_NFSD is selected.
  28
  29          If unsure, say N.

  37        depends on NFSD
  38        help
  39          This option enables support in your system's NFS server for
  40          version 3 of the NFS protocol (RFC 1813).
  41
  42          If unsure, say Y.

  44config NFSD_V3_ACL
  45        bool "NFS server support for the NFSv3 ACL protocol extension"
  46        depends on NFSD_V3
  47        select NFSD_V2_ACL
  48        help
  49          Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
  50          never became an official part of the NFS version 3 protocol.
  51          This protocol extension allows applications on NFS clients to
  52          manipulate POSIX Access Control Lists on files residing on NFS
  53          servers.  NFS servers enforce POSIX ACLs on local files whether
  54          this protocol is available or not.
  55
  56          This option enables support in your system's NFS server for the
  57          NFSv3 ACL protocol extension allowing NFS clients to manipulate
  58          POSIX ACLs on files exported by your system's NFS server.  NFS
  59          clients which support the Solaris NFSv3 ACL protocol can then
  60          access and modify ACLs on your NFS server.
  61
  62          To store ACLs on your NFS server, you also need to enable ACL-
  63          related CONFIG options for your local file systems of choice.
  64
  65          If unsure, say N.
  66

  74        help
  75          This option enables support in your system's NFS server for
  76          version 4 of the NFS protocol (RFC 3530).
  77
  78          To export files using NFSv4, you need to install additional user
  79          space programs which can be found in the Linux nfs-utils package,
  80          available from http://linux-nfs.org/.
  81
  82          If unsure, say N.

  84config NFSD_V4_SECURITY_LABEL
  85        bool "Provide Security Label support for NFSv4 server"
  86        depends on NFSD_V4 && SECURITY
  87        help
  88
  89        Say Y here if you want enable fine-grained security label attribute
  90        support for NFS version 4.  Security labels allow security modules like
  91        SELinux and Smack to label files to facilitate enforcement of their policies.
  92        Without this an NFSv4 mount will have the same label on each file.
  93
  94        If you do not wish to enable fine-grained security labels SELinux or
  95        Smack policies on NFSv4 files, say N.
  96
  97        WARNING: there is still a chance of backwards-incompatible protocol changes.
  98        For now we recommend "Y" only for developers and testers."

 100config NFSD_FAULT_INJECTION
 101        bool "NFS server manual fault injection"
 102        depends on NFSD_V4 && DEBUG_KERNEL
 103        help
 104          This option enables support for manually injecting faults
 105          into the NFS server.  This is intended to be used for
 106          testing error recovery on the NFS client.
 107
 108          If unsure, say N.
