  • e8896495b   NFS: Check lengths more thoroughly in NFS4 readdir XDR decode ... Browse Code »

    Check the bounds of length specifiers more thoroughly in the XDR decoding of
    NFS4 readdir reply data.

    Currently, if the server returns a bitmap or attr length that causes the
    current decode point pointer to wrap, this could go undetected (consider a
    small "negative" length on a 32-bit machine).

    Also add a check into the main XDR decode handler to make sure that the amount
    of data is a multiple of four bytes (as specified by RFC-1014). This makes
    sure that we can do u32* pointer subtraction in the NFS client without risking
    an undefined result (the result is undefined if the pointers are not correctly
    aligned with respect to one another).

  • e8c96f8c2   [PATCH] fs: Use ARRAY_SIZE macro ... Browse Code »

    Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove a
    duplicate of ARRAY_SIZE. Some trailing whitespaces are also deleted.

  • cc0175c1d   SUNRPC: display human-readable procedure name in rpc_iostats output ... Browse Code »

    Add fields to the rpc_procinfo struct that allow the display of a
    human-readable name for each procedure in the rpc_iostats output.

    Also fix it so that the NFSv4 stats are broken up correctly by
    sub-procedure number. NFSv4 uses only two real RPC procedures:
    NULL, and COMPOUND.

    Test plan:
    Mount with NFSv2, NFSv3, and NFSv4, and do "cat /proc/self/mountstats".

  • 8c233cf9c   NFSv4: handle no acl attr ... Browse Code »

    Stop handing garbage to userspace in the case where a weird server clears the
    acl bit in the getattr return (despite the fact that they've already claimed
    acl support.)

  • 9512135df   NFSv4: Fix a potential CLOSE race ... Browse Code »

    Once the state_owner and lock_owner semaphores get removed, it will be
    possible for other OPEN requests to reopen the same file if they have
    lower sequence ids than our CLOSE call.
    This patch ensures that we recheck the file state once
    nfs_wait_on_sequence() has completed waiting.

  • cee54fc94   NFSv4: Add functions to order RPC calls ... Browse Code »

    NFSv4 file state-changing functions such as OPEN, CLOSE, LOCK,... are all
    labelled with "sequence identifiers" in order to prevent the server from
    reordering RPC requests, as this could cause its file state to
    become out of sync with the client.

    Currently the NFS client code enforces this ordering locally using
    semaphores to restrict access to structures until the RPC call is done.
    This, of course, only works with synchronous RPC calls, since the
    user process must first grab the semaphore.
    By dropping semaphores, and instead teaching the RPC engine to hold
    the RPC calls until they are ready to be sent, we can extend this
    process to work nicely with asynchronous RPC calls too.

    This patch adds a new list called "rpc_sequence" that defines the order
    of the RPC calls to be sent. We add one such list for each state_owner.
    When an RPC call is ready to be sent, it checks if it is top of the
    rpc_sequence list. If so, it proceeds. If not, it goes back to sleep,
    and loops until it hits top of the list.
    Once the RPC call has completed, it can then bump the sequence id counter,
    and remove itself from the rpc_sequence list, and then wake up the next
    sleeper.

    Note that the state_owner sequence ids and lock_owner sequence ids are
    all indexed to the same rpc_sequence list, so OPEN, LOCK,... requests
    are all ordered w.r.t. each other.
