2015-11-11qga: fix append file open modes for win32Kirk Allan1-14/+15
For append file open modes, use FILE_APPEND_DATA for the desired access for writing at the end of the file. Version 2: For "a+", "ab+", and "a+b" modes use FILE_APPEND_DATA|GENERIC_READ. ORing in GENERIC_READ starts a read at the begining of the file. All writes will append to the end fo the file. Added white space to maintain the alignment of the guest_file_open_modes[]. Signed-off-by: Kirk Allan <kallan@suse.com> Cc: qemu-stable@nongnu.org * use FILE_GENERIC_APPEND macro, which provides same semantics as FILE_APPEND_DATA, but retains other flags from GENERIC_WRITE Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2015-11-04qga: set file descriptor in qmp_guest_file_open non-blocking on Win32Olga Krishtal1-0/+27
Set fd non-blocking to avoid common use cases (like reading from a named pipe) from hanging the agent. This was missed in the original code. The patch introduces qemu_set_handle_nonoblocking, the local analog of qemu_set_nonblock for HANDLES. The usage of handles in qemu_set_non/block is impossible, because for win32 there is a difference between file discriptors and file handles, and all file ops are made via Win32 api.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2015-09-10error: On abort, report where the error was createdMarkus Armbruster3-5/+8
This is particularly useful when we abort in error_propagate(), because there the stack backtrace doesn't lead to where the error was created. Looks like this: Unexpected error in parse_block_error_action() at .../qemu/blockdev.c:322: qemu-system-x86_64: -drive if=none,werror=foo: 'foo' invalid write error action Aborted (core dumped) Note: to get this example output, I monkey-patched drive_new() to pass &error_abort to blockdev_init(). To keep the error handling boiler plate from growing even more, all error_setFOO() become macros expanding into error_setFOO_internal() with additional __FILE__, __LINE__, __func__ arguments. Not exactly pretty, but it works. The macro trickery breaks down when you take the address of an error_setFOO(). Fortunately, we do that in just one place: qemu-ga's Windows VSS provider and requester DLL wants to call error_setg_win32() through a function pointer "to avoid linking glib to the DLL". Use error_setg_win32_internal() there. The use of the function pointer is already wrapped in a macro, so the churn isn't bad. Code size increases by some 35KiB for me (0.7%). Tolerable. Could be less if we passed relative rather than absolute source file names to the compiler, or forwent reporting __func__.

2015-09-10qga/vss-win32: Document the DLL requires non-null errpMarkus Armbruster3-2/+4
requester.cpp uses this pattern to receive an error and pass it on to the caller (err_is_set() macro peeled off for clarity): ... code that may set errset->errp ... if (errset->errp && *errset->errp) { ... handle error ... } This breaks when errset->errp is null. As far as I can tell, it currently isn't, so this is merely fragile, not actually broken. The robust way to do this is to receive the error in a local variable, then propagate it up, like this: Error *err = NULL; ... code that may set err ... if (err) ... handle error ... error_propagate(errset->errp, err); } See also commit 5e54769, 0f230bf, a903f40.

2015-09-10qga: Clean up unnecessarily dirty castsMarkus Armbruster3-9/+9
qga_vss_fsfreeze() casts error_set_win32() from void (*)(Error **, int, ErrorClass, const char *, ...) to void (*)(void **, int, int, const char *, ...) The result is later called. Since the two types are not compatible, the call is undefined behavior. It works in practice anyway. However, there's no real need for trickery here. Clean it up as follows: * Declare struct Error, and fix the first parameter. * Switch to error_setg_win32(). This gets rid of the troublesome ErrorClass parameter. Requires converting error_setg_win32() from macro to function, but that's trivially easy, because this is the only user of error_set_win32().

Previously, running the .msi would unregister the QEMU GA VSS service if QEMU GA was already installed on the machine, and then register it only if QEMU GA was NOT previously installed. This behavior caused the service to be registered only after the INITIAL installation, and any subsequent run of the .msi (to redo, repair, or upgrade the installation) ended in the service being unregistered. Now, the VSS service is still unregistered if QEMU GA is already installed (so that a fix or an update could be performed) but then it is registered again (if the GA is not being uninstalled) thus finishing the repair/upgrade correctly. Additionally, downgrading is now prevented. If a user would like to downgrade a version, he/she must uninstall the newer version first.

The lookup is performed for every volume available. However, this information is not mandatory for vss-provider. In order to use SetupApi we need to notify linker about it.

We should use GetVolumeXXX api to work with volumes. This will help us to resolve the situation with volumes without drive letter, i.e. when the volume is mounted as a folder. Such volume is called mounted folder. This volume is a regular mounted volume from all other points of view. The information about non mounted volume is reported as System Reserved. This volume is not mounted and thus it is not writable. GuestDiskAddressList API is not used because operations are performed with volumes but no with disks. This means that spanned disk will be counted and handled as a single volume. It is worth mentioning that the information about every disk in the volume can be queried via IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

2015-07-07qga: win32 qmp_guest_network_get_interfaces implementationKirk Allan1-3/+216
By default, IPv4 prefixes will be derived by matching the address to those returned by GetAdaptersInfo. IPv6 prefixes can not be matched this way due to the unpredictable order of entries. In Windows Vista/2008 guests and newer, both IPv4 and IPv6 prefixes can be retrieved from OnLinkPrefixLength. Setting --extra-cflags in the build configuration to "-D_WIN32_WINNT=0x600" or greater makes OnLinkPrefixLength available. Setting --extra-cflags is not required and if not set, the default approach to get the prefix will be taken.

2015-07-07Revert "guest agent: remove g_strcmp0 usage"Markus Armbruster1-1/+1
Since we now require GLib 2.22+ (commit f40685c), we don't have to work around lack of g_strcmp0() anymore. This reverts commit 8f4774789947bc4bc4c8d026a289fe980d3d2ee1.

2015-07-07qga/qmp_guest_fstrim: Return per path fstrim resultJustin Ossevoort3-17/+71
The current guest-fstrim support only returns an error if some mountpoint was unable to be trimmed, skipping any possible additional mountpoints. The result of the TRIM operation itself is also discarded. This change returns a per mountpoint result of the TRIM operation. If an error occurs on some mountpoints that error is returned and the guest-fstrim continue with any additional mountpoints. The returned values for errors, minimum and trimmed are dependant on the filesystem, storage stacks and kernel version.

2015-07-07qga/commands-posix: Fix bug in guest-fstrimJustin Ossevoort1-5/+4
The FITRIM ioctl updates the fstrim_range structure it receives. This way the caller can determine how many bytes were trimmed. The guest-fstrim logic reuses the same fstrim_range for each filesystem, effectively limiting each filesystem to trim at most as much as the previous was able to trim. If a previous filesystem would have trimmed 0 bytes, than the next filesystem would report an error 'Invalid argument' because a FITRIM request with length 0 is not valid. This change resets the fstrim_range structure for each filesystem.
