This patch will send NOP-Out PDUs every 5 seconds to the iSCSI target. If a consecutive number of NOP-In replies fail a reconnect is initiated. iSCSI NOPs help to ensure that the connection to the target is still operational. This should not, but in reality may be the case even if the TCP connection is still alive if there are bugs in either the target or the initiator implementation. v2: - track the NOPs inside libiscsi so libiscsi can reset the counter in case it initiates a reconnect.

libiscsi expects all write16 data in a linear buffer. If the iovec only contains one buffer we can skip the linearization step as well as the additional malloc/free and pass the buffer directly.

The commit 258711 introduced MemoryRegion to replace ioport_region* for ioport 80h and F0h. A MemoryRegion needs to have both read and write callback otherwise a segfault will occur when an access is made. The previous behaviour of this both ioport is to return 0xffffffffffffffff. So keep this behaviour.

Starting with release 1.4 we have a fully functional q35 machine type, i.e. "qemu -M q35" JustWorks[tm]. Update machine type names to reflect that: * pc-1.4 becomes pc-i440fx-1.4 * q35-next becomes pc-q35-1.4 The pc-1.3 (+older) names are maintained for compatibility reasons. For the same reason the "pc" and "q35" aliases are kept. pc-piix-1.4 continues to be the default machine type, again for compatibility reasons. Also updated the description (shown by "qemu -M ?") with host bridge name, south bridge name and chipset release year. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Since 39bffca2 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

The current implementation of os_host_main_loop_wait() on Windows, returns 1 only when a g_poll() event occurs because the return value of select() is overridden. This is wrong as we may skip a socket event, as shown in this example: 1. select() returns 0 2. g_poll() returns 1 (socket event occurs) 3. os_host_main_loop_wait() returns 1 4. qemu_iohandler_poll() sees no socket event because select() has return before the event occurs 5. select() returns 1 6. g_poll() returns 0 (g_poll overrides select's return value) 7. os_host_main_loop_wait() returns 0 8. qemu_iohandler_poll() doesn't check for socket events because the return value of os_host_main_loop_wait() is zero. 9. goto 5 This patch use one variable for each of these return values, so we don't miss a select() event anymore. Also move the call to select() after g_poll(), this will improve latency as we don't have to go through two os_host_main_loop_wait() calls to detect a socket event.

To use the online disk snapshot for online-backup, application-level consistency of the snapshot image is required. However, currently the guest agent can provide only filesystem-level consistency, and the snapshot may contain dirty data, for example, incomplete transactions. This patch provides the opportunity to quiesce applications before snapshot is taken. If --fsfreeze-hook option is specified, the hook is executed with "freeze" argument before the filesystem is frozen by fsfreeze-freeze command. As for fsfreeze-thaw command, the hook is executed with "thaw" argument after the filesystem is thawed.

VFIO_PCI_NUM_REGIONS and VFIO_PCI_NUM_IRQS should never have been used in this manner as it locks a specific kernel implementation.

Guests typically enable MSI-X with all of the vectors in the MSI-X vector table masked. Only when the vector is enabled does the vector get unmasked, resulting in a vector_use callback. These two points, enable and unmask, correspond to pci_enable_msix() and request_irq() for Linux guests. Some drivers rely on VF/PF or PF/fw communication channels that expect the physical state of the device to match the guest visible state of the device. They don't appreciate lazily enabling MSI-X on the physical device. To solve this, enable MSI-X with a single vector when the MSI-X capability is enabled and immediate disable the vector. This leaves the physical device in exactly the same state between host and guest. Furthermore, the brief gap where we enable vector 0, it fires into userspace, not KVM, so the guest doesn't get spurious interrupts. Ideally we could call VFIO_DEVICE_SET_IRQS with the right parameters to enable MSI-X with zero vectors, but this will currently return an error as the Linux MSI-X interfaces do not allow it.
