  • bf118a342   NFSv4: include bitmap in nfsv4 get acl data ... Browse Code »
    129

    The NFSv4 bitmap size is unbounded: a server can return an arbitrary
    sized bitmap in an FATTR4_WORD0_ACL request. Replace using the
    nfs4_fattr_bitmap_maxsz as a guess to the maximum bitmask returned by a server
    with the inclusion of the bitmap (xdr length plus bitmasks) and the acl data
    xdr length to the (cached) acl page data.

    This is a general solution to commit e5012d1f "NFSv4.1: update
    nfs4_fattr_bitmap_maxsz" and fixes hitting a BUG_ON in xdr_shrink_bufhead
    when getting ACLs.

    Fix a bug in decode_getacl that returned -EINVAL on ACLs > page when getxattr
    was called with a NULL buffer, preventing ACL > PAGE_SIZE from being retrieved.

    vm_map_ram() is not available on NOMMU platforms, and causes trouble
    on incoherrent architectures such as ARM when we access the page data
    through both the direct and the virtual mapping.

    The alternative is to use the direct mapping to access page data
    for the case when we are not crossing a page boundary, but to copy
    the data into a linear scratch buffer when we are accessing data
    that spans page boundaries.

  • bf2695516   SUNRPC: New xdr_streams XDR decoder API ... Browse Code »

    Now that all client-side XDR decoder routines use xdr_streams, there
    should be no need to support the legacy calling sequence [rpc_rqst *,
    __be32 *, RPC res *] anywhere. We can construct an xdr_stream in the
    generic RPC code, instead of in each decoder function.

    This is a refactoring change. It should not cause different behavior.

    Now that all client-side XDR encoder routines use xdr_streams, there
    should be no need to support the legacy calling sequence [rpc_rqst *,
    __be32 *, RPC arg *] anywhere. We can construct an xdr_stream in the
    generic RPC code, instead of in each encoder function.

    Also, all the client-side encoder functions return 0 now, making a
    return value superfluous. Take this opportunity to convert them to
    return void instead.

    This is a refactoring change. It should not cause different behavior.

  • 405f55712   headers: smp_lock.h redux ... Browse Code »

    * Remove smp_lock.h from files which don't need it (including some headers!)
    * Add smp_lock.h to files which do need it
    * Make smp_lock.h include conditional in hardirq.h
    It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

    This will make hardirq.h inclusion cheaper for every PREEMPT=n config
    (which includes allmodconfig/allyesconfig, BTW)

  • 88a9fe8ca   SUNRPC: Remove the last remnant of the BKL... ... Browse Code »

    Somehow, this escaped the previous purge. There should be no need to keep
    any extra locks in the XDR callbacks.

    The NFS client XDR code only writes into private objects, whereas all reads
    of shared objects are confined to fields that do not change, such as
    filehandles...

    Ditto for lockd, the NFSv2/v3 client mount code, and rpcbind.

    The nfsd XDR code may require the BKL, but since it does a synchronous RPC
    call from a thread that already holds the lock, that issue is moot.

  • e5cff482c   SUNRPC: Use unsigned string lengths in xdr_decode_string_inplace ... Browse Code »

    XDR strings, opaques, and net objects should all use unsigned lengths.
    To wit, RFC 4506 says:

    4.2. Unsigned Integer

    An XDR unsigned integer is a 32-bit datum that encodes a non-negative
    integer in the range [0,4294967295].

    ...

    4.11. String

    The standard defines a string of n (numbered 0 through n-1) ASCII
    bytes to be the number n encoded as an unsigned integer (as described
    above), and followed by the n bytes of the string.

    After this patch, xdr_decode_string_inplace now matches the other XDR
    string and array helpers that take a string length argument. See:

    xdr_encode_opaque_fixed, xdr_encode_opaque, xdr_encode_array

  • 9d2923169   SUNRPC: skb_read_bits is the same as xs_tcp_copy_data ... Browse Code »

    Clean-up: eliminate xs_tcp_copy_data -- it's exactly the same logic as the
    common routine skb_read_bits. The UDP and TCP socket read code now share
    the same routine for copying data into an xdr_buf.

    Now that skb_read_bits() is exported, rename it to avoid confusing it with
    a generic skb_* function. As these functions are XDR-specific, they should
    not have names that suggest they are of generic use. Also rename
    skb_read_and_csum_bits() to be consistent.

  • d343fce14   [PATCH] knfsd: Allow lockd to drop replies as appropriate ... Browse Code »

    It is possible for the ->fopen callback from lockd into nfsd to find that an
    answer cannot be given straight away (an upcall is needed) and so the request
    has to be 'dropped', to be retried later. That error status is not currently
    propagated back.

    So:
    Change nlm_fopen to return nlm error codes (rather than a private
    protocol) and define a new nlm_drop_reply code.
    Cause nlm_drop_reply to cause the rpc request to get rpc_drop_reply
    when this error comes back.
    Cause svc_process to drop a request which returns a status of
    rpc_drop_reply.

  • 40859d7ee   NFS: support large reads and writes on the wire ... Browse Code »

    Most NFS server implementations allow up to 64KB reads and writes on the
    wire. The Solaris NFS server allows up to a megabyte, for instance.

    Now the Linux NFS client supports transfer sizes up to 1MB, too. This will
    help reduce protocol and context switch overhead on read/write intensive NFS
    workloads, and support larger atomic read and write operations on servers
    that support them.

    Test-plan:
    Connectathon and iozone on mount point with wsize=rsize>32768 over TCP.
    Tests with NFS over UDP to verify the maximum RPC payload size cap.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
