| | | | | | | | | | | | | | | | Add API and stubs for new guest-get-disks command. The command guest-get-fsinfo can be used to list information about disks and partitions but it is limited only to mounted disks with filesystem. This new command should allow listing information about disks of the VM regardles whether they are mounted or not. This can be usefull for management applications for mapping virtualized devices or pass-through devices to device names in the guest OS.

| | | | | | | | | | | | | | | Simple unions are simpler than flat unions in the schema, but more complicated in C and on the QMP wire: there's extra indirection in C and extra nesting on the wire, both pointless. They should be avoided in new code. GuestDeviceId was recently added for guest-get-devices. Convert it to a flat union.

* qga-win: Fix guest-get-devices error API violationsMarkus Armbruster2020-11-021-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. qmp_guest_get_devices() is wrong that way: it calls error_setg() in a loop. If no iteration fails, the function returns a value and sets no error. Okay. If exactly one iteration fails, the function returns a value and sets an error. Wrong. If multiple iterations fail, the function trips error_setv()'s assertion. Fix it to return immediately on error. Perhaps the failure to convert the driver version to UTF-8 should not be an error. We could simply not report the botched version string instead. Drop a superfluous continue while there.

The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually. One nested declaration of @local_err deleted manually. Preexisting unwanted blank line dropped in hw/riscv/sifive_e.c.

When we have at most one other path that actually needs to propagate, and maybe one at the end that where propagation is unnecessary, e.g. foo(..., &err); if (err) { goto out; } ... bar(..., &err); out: error_propagate(errp, err); return; move the error_propagate() to where it's needed, like if (...) { foo(..., &err); error_propagate(errp, err); return; } ... bar(..., errp); return; and transform the error_setg() as above. In some places, the transformation results in obviously unnecessary error_propagate(). The next few commits will eliminate them. Bonus: the elimination of gotos will make later patches in this series easier to review.

| | | | | | | | | | | | | | | | | | | | | Since Windows Server 2016, Microsoft stopped upgrading the major and minor versions of their new Windows Server product, so, the current functionality of checking major and minor version numbers to determine the Windows Server version wont work as expected. The implemented solution here is to use the build number in addition to the major and minor version numbers of the product to determine the Windows Server product version. The final build number of Windows Server 2016 is 14939, and the final build number of Windows Server 2019 is 17764, so any Windows Server product that has the major version of 10 and minor version of 0 with a build number lower or equal to 14939 will resemble 2016 and if the build number is lower or equal to 17763 will resemble 2019.

* qga: Support Unicode paths in guest-file-open on win32Jonathon Reinhart2018-10-301-5/+19
| | | | | | | | | | | | | | Currently, the win32 port of QEMU Guest Agent does not properly handle Unicode paths. The JSON decoder produces a valid UTF-8 path string, but this is passed directly to CreateFileA, which is expecting an ANSI string and not UTF-8. This leads to mangled filenames. This patch follows the example of qmp_guest_set_user_password() and uses g_utf8_to_utf16() to convert the string to UTF-16 and calls CreateFileW() explicitly.
