      nfsd: Use correct credential for NFSv4.0 callback with GSS · cb25e7b2
      Chuck Lever authored
      I've had trouble when operating a multi-homed Linux NFS server with
      Kerberos using NFSv4.0. Lately, I've seen my clients reporting
      this (and then hanging):
      
      May  9 11:43:26 manet kernel: NFS: NFSv4 callback contains invalid cred
      
      The client-side commit f11b2a1c ("nfs4: copy acceptor name from
      context to nfs_client") appears to be related, but I suspect this
      problem has been going on for some time before that.
      
      RFC 7530 Section 3.3.3 says:
      > For Kerberos V5, nfs/hostname would be a server principal in the
      > Kerberos Key Distribution Center database.  This is the same
      > principal the client acquired a GSS-API context for when it issued
      > the SETCLIENTID operation ...
      
      In other words, an NFSv4.0 client expects that the server will use
      the same GSS principal for callback that the client used to
      establish its lease. For example, if the client used the service
      principal "nfs@server.domain" to establish its lease, the server
      is required to use "nfs@server.domain" when performing NFSv4.0
      callback operations.
      
      The Linux NFS server currently does not. It uses a common service
      principal for all callback connections. Sometimes this works as
      expected, and other times -- for example, when the server is
      accessible via multiple hostnames -- it won't work at all.
      
      This patch scrapes the target name from the client credential,
      and uses that for the NFSv4.0 callback credential. That should
      be correct much more often.

      sunrpc: Extract target name into svc_cred · 9abdda5d
      Chuck Lever authored
      NFSv4.0 callback needs to know the GSS target name the client used
      when it established its lease. That information is available from
      the GSS context created by gssproxy. Make it available in each
      svc_cred.
      
      Note this will also give us access to the real target service
      principal name (which is typically "nfs", but spec does not require
      that).

      sunrpc: Enable the kernel to specify the hostname part of service principals · a1a23777
      Chuck Lever authored
      A multi-homed NFS server may have more than one "nfs" key in its
      keytab. Enable the kernel to pick the key it wants as a machine
      credential when establishing a GSS context.
      
      This is useful for GSS-protected NFSv4.0 callbacks, which are
      required by RFC 7530 S3.3.3 to use the same principal as the service
      principal the client used when establishing its lease.
      
      A complementary modification to rpc.gssd is required to fully enable
      this feature.

      Pull RISC-V updates from Palmer Dabbelt:
       "This contains some small RISC-V updates I'd like to target for 4.18.
      
        They are all fairly small this time. Here's a short summary, there's
        more info in the commits/merges:
      
         - a fix to __clear_user to respect the passed arguments.
      
         - enough support for the perf subsystem to work with RISC-V's ISA
           defined performance counters.
      
         - support for sparse and cleanups suggested by it.
      
         - support for R_RISCV_32 (a relocation, not the 32-bit ISA).
      
         - some MAINTAINERS cleanups.
      
         - the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's
           always present.
      
        I've given these a simple build+boot test"
