2016-03-14blockdev: Snapshotting must not open second instance of old topKevin Wolf1-1/+6
Calling bdrv_img_create() with a size of -1 means that it determines the size automatically by opening the backing file. However, in the case of live snapshots, the backing file is already opened and we must avoid opening the same image twice at the same time. Apart from that, just getting the size from the already existing BDS is a lot less overhead than opening a new instance.

2016-03-14block/vpc: give option to force the current_size field in .bdrv_createJeff Cody1-7/+35
When QEMU creates a VHD image, it goes by the original spec, calculating the current_size based on the nearest CHS geometry (with an exception for disks > 127GB). Apparently, Azure will only allow images that are sized to the nearest MB, and the current_size as calculated from CHS cannot guarantee that. Allow QEMU to create images similar to how Hyper-V creates images, by setting current_size to the specified virtual disk size. This introduces an option, force_size, to be passed to the vpc format during image creation, e.g.: qemu-img convert -f raw -o force_size -O vpc test.img test.vhd When using the "force_size" option, the creator app field used by QEMU will be "qem2" instead of "qemu", to indicate the difference. In light of this, we also add parsing of the "qem2" field during vpc_open.

2016-03-14block/vpc: choose size calculation method based on creator_app fieldJeff Cody1-5/+82
The VHD file format is used by both Virtual PC, and Hyper-V. However, how the virtual disk size is calculated varies between the two. Virtual PC uses the CHS drive parameters to determine the drive size. Hyper-V, on the other hand, uses the current_size field in the footer when determining image size. This is problematic for a few reasons: * VHD images from Hyper-V, using CHS calculations, will likely be trunctated. * If we just rely always on current_size, then QEMU may have data compatibility issues with Virtual PC (we may write too much data into a VHD file to be used by Virtual PC, for instance). * Existing VHD images created by QEMU have used the CHS calculations, except for images exceeding the 127GB limit. We want to remain compatible with our own generated images. Luckily, the VHD specification defines a 'Creator App' field, that is used to indicate what software created the VHD file. This patch does two things: 1. Uses the 'Creator App' field to help determine how to calculate size, and 2. Adds a VPC format option 'force_size_calc', so that the user can override the 'Creator App' auto-detection, in case there exist VHD images with unknown or contradictory 'Creator App' entries. N.B.: We currently use the maximum CHS value as an indication to use the current_size field. This patch does not change that, even with the 'force_size_calc' option.

2016-03-10osdep: remove use of socket_error() from all codeDaniel P. Berrange11-63/+46
Now that QEMU wraps the Win32 sockets methods to automatically set errno upon failure, there is no reason for callers to use the socket_error() method. They can rely on accessing errno even on Win32. Remove all use of socket_error() from general code, leaving it as a static method in oslib-win32.c only. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2016-03-10osdep: add wrappers for socket functionsDaniel P. Berrange7-19/+291
The windows socket functions look identical to the normal POSIX sockets functions, but instead of setting errno, the caller needs to call WSAGetLastError(). QEMU has tried to deal with this incompatibility by defining a socket_error() method that callers must use that abstracts the difference between WSAGetLastError() and errno. This approach is somewhat error prone though - many callers of the sockets functions are just using errno directly because it is easy to forget the need use a QEMU specific wrapper. It is not always immediately obvious that a particular function will in fact call into Windows sockets functions, so the dev may not even realize they need to use socket_error(). This introduces an alternative approach to portability inspired by the way GNULIB fixes portability problems. We use a macro to redefine the original socket function names to refer to a QEMU wrapper function. The wrapper function calls the original Win32 sockets method and then sets errno from the WSAGetLastError() value. Thus all code can simply call the normal POSIX sockets APIs are have standard errno reporting on error, even on Windows. This makes the socket_error() method obsolete. We also bring closesocket & ioctlsocket into this approach. Even though they are non-standard Win32 names, we can't wrap the normal close/ioctl methods since there's no reliable way to distinguish between a file descriptor and HANDLE in Win32.

2016-03-10char: remove qemu_chr_open_socket_fd methodDaniel P. Berrange1-35/+24
The qemu_chr_open_socket_fd method takes care of either doing a synchronous socket connect, or creating a listener socket. Part of the work when creating the listener socket is to register a watch for incoming clients. The caller of qemu_chr_open_socket_fd may not want this watch created, as it might be doing a synchronous wait for the first client. Rather than passing yet more parameters into qemu_chr_open_socket_fd to let it handle this, just remove the qemu_chr_open_socket_fd method an inline its functionality into the caller. This allows for a clearer control flow and shorter code. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2016-03-10char: remove socket_try_connect methodDaniel P. Berrange1-15/+10
The qemu_chr_open_socket_fd() method multiplexes three different actions into one method. The socket_try_connect() method is one of its callers, but it only ever want one specific action performed. By inlining that action into socket_try_connect() we see that there is not in fact any failure scenario, so there is not even any reason for socket_try_connect to exist. Just inline the asynchronous connection attempts directly at the places that need them. This shortens & clarifies the code. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Daniel P.

2016-03-10io: implement socket watch for win32 using WSAEventSelect+selectPaolo Bonzini4-7/+170
On Win32 we cannot directly poll on socket handles. Instead we create a Win32 event object and associate the socket handle with the event. When the event signals readyness we then have to use select to determine which events are ready. Creating Win32 events is moderately heavyweight, so we don't want todo it every time we create a GSource, so this associates a single event with a QIOChannel.

2016-03-10osdep: fix socket_error() to work with Mingw64Daniel P. Berrange4-30/+81
Historically QEMU has had a socket_error() macro that was defined to map to WSASocketError(). The os-win32.h header file would define errno constants that mapped to the WSA error constants. This worked fine with Mingw32 since its header files never defined any errno values, nor did it even provide an errno.h. So callers of socket_error() could match on traditional Exxxx constants and it would all "just work". With Mingw64 though, things work rather differently. First there is an errno.h file which defines all the traditional errno constants you'd expect from a UNIX platform. There is then a winerror.h which defined the WSA error constants. Crucially the WSAExxxx errno values in winerror.h do not match the Exxxx errno values in error.h. If QEMU had only imported winerror.h it would still work, but the qemu/osdep.h file unconditionally imports errno.h. So callers of socket_error() will get now WSAExxxx values back and compare them to the Exxx constants. This will always fail silently at runtime. To solve this QEMU needs to stop assuming the WSAExxxx constant values match the Exxx constant values. Thus the socket_error() macro is turned into a small function that re-maps WSAExxxx values into Exxx. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Daniel P.
