    Currently some "Unspecified error 0x80004005" is reported on the Windows
    side if something fails. Handle the ENOSPC case and return
    ERROR_DISK_FULL, which allows at least Copy-VMFile to report a meaning
    full error.

  • 31d4ea1a0   Drivers: hv: util: make struct hv_do_fcopy match Hyper-V host messages ... Browse Code »

    An attempt to fix fcopy on i586 (bc5a5b0 Drivers: hv: util: Properly pack the data
    for file copy functionality) led to a regression on x86_64 (and actually didn't fix
    i586 breakage). Fcopy messages from Hyper-V host come in the following format:

    struct do_fcopy_hdr | 36 bytes
    0000 | 4 bytes
    offset | 8 bytes
    size | 4 bytes
    data | 6144 bytes

    On x86_64 struct hv_do_fcopy matched this format without ' __attribute__((packed))'
    and on i586 adding ' __attribute__((packed))' to it doesn't change anything. Keep
    the structure packed and add padding to match re reality. Tested both i586 and x86_64
    on Hyper-V Server 2012 R2.

  • 01325476d   Drivers: hv: Implement the file copy service ... Browse Code »

    Implement the file copy service for Linux guests on Hyper-V. This permits the
    host to copy a file (over VMBUS) into the guest. This facility is part of
    "guest integration services" supported on the Windows platform.
    Here is a link that provides additional details on this functionality:

    http://technet.microsoft.com/en-us/library/dn464282.aspx

    In V1 version of the patch I have addressed comments from
    Olaf Hering and Dan Carpenter

    In V2 version of this patch I did some minor cleanup (making some globals
    static). In V4 version of the patch I have addressed all of Olaf's
    most recent set of comments/concerns.

    In V5 version of the patch I had addressed Greg's most recent comments.
    I would like to thank Greg for suggesting that I use misc device; it has
    significantly simplified the code.

    In V6 version of the patch I have cleaned up error message based on Olaf's
    comments. I have also rebased the patch based on the current tip.

    In this version of the patch, I have addressed the latest comments from Greg.

  • 5267cf02c   hv: Add hyperv.h to uapi headers ... Browse Code »

    This patch adds the hyperv.h header to the uapi folder, and adds it to the Kbuild file.
    Doing this enables compiling userspace Hyper-V tools using the installed headers.

    Version 2: Split UAPI parts into new header, instead of duplicating.
