2015-06-12Add a protective section footerDr. David Alan Gilbert
Badly formatted migration streams can go undetected or produce misleading errors due to a lock of checking at the end of sections. In particular a section that adds an extra 0x00 at the end causes what looks like a normal end of stream and thus doesn't produce any errors, and something that ends in a 0x01..0x04 kind of look like real section headers and then fail when the section parser tries to figure out which section they are. This is made worse by the choice of 0x00..0x04 being small numbers that are particularly common in normal section data. This patch adds a section footer consisting of a marker (0x7e - ~) followed by the section-id that was also sent in the header. If they mismatch then it throws an error explaining which section was being loaded.

2015-06-11i386/acpi-build: fix PXB workarounds for unsupported BIOSesLaszlo Ersek
The patch apci: fix PXB behaviour if used with unsupported BIOS uses the following condition to see if a "PXB mem/IO chunk" has *not* been configured by the BIOS: (!range_base || range_base > range_limit) When this condition evaluates to true, said patch *omits* the corresponding entry from the _CRS. Later on the patch checks for the opposite condition (with the intent of *adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been configured). Unfortunately, the condition was negated incorrectly: only the first ! operator was removed, which led to the nonsensical expression (range_base || range_base > range_limit) leading to bogus entries in the _CRS, and causing BSOD in Windows Server 2012 R2 when it runs on OVMF. The correct negative of the condition seen at the top is (range_base && range_base <= range_limit) Fix the expressions. Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.

2015-06-11i386/acpi-build: more traditional _UID and _HID for PXB root busesLaszlo Ersek
The ACPI specification permits the _HID and _UID objects to evaluate to strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in the ACPI v6.0 spec.) With regard to related standards, the UEFI specification can also express a device address composed from string _HID and _UID identifiers, inside the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table 49, in the UEFI v2.5 spec.) However, numeric (integer) contents for both _HID and _UID are more traditional. They are recommended by the UEFI spec for size reasons: [...] the ACPI Device Path node is smaller and should be used if possible to reduce the size of device paths that may potentially be stored in nonvolatile storage [...] External tools support them better (for example the --acpi_hid and --acpi_uid options of "efibootmgr" only take numeric identifiers). Finally, numeric _HID and _UID contents are existing practice in the QEMU source. This patch was tested with a Fedora 20 LiveCD and a preexistent Windows Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we get, in the SSDT: > Scope (\_SB) > { > Device (PC04) > { > Name (_UID, 0x04) // _UID: Unique ID > Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.
