2019-02-05keymap: fix keyup mappingsGerd Hoffmann
It is possible that the modifier state on keyup is different from the modifier state on keydown. In that case the keycode lookup can end up with different keys in case multiple keysym -> keycode mappings exist, because it picks the mapping depending on modifier state. To fix that change the lookup logic for keyup events. Instead of looking at the modifier state check the key state and prefer a keycodes where the key is in "down" state right now.

2019-02-05kbd-state: add keyboard state trackerGerd Hoffmann
Now that most user interfaces are using QKeyCodes it is easier to have common keyboard code useable by all user interfaces. This patch adds helper code to track the state of all keyboard keys, using a bitmap indexed by QKeyCode. Modifier state is tracked too, as separate bitmap. That makes checking modifier state easier. Likewise we can easily apply special handling for capslock & numlock (toggles on keypress) and ctrl + shift (we have two keys for that).

2019-02-04qemu-nbd: Deprecate qemu-nbd --partitionEric Blake
The existing qemu-nbd --partition code claims to handle logical partitions up to 8, since its introduction in 2008 (commit 7a5ca86). However, the implementation is bogus (actual MBR logical partitions form a sort of linked list, with one partition per extended table entry, rather than four logical partitions in a single extended table), making the code unlikely to work for anything beyond -P5 on actual guest images. What's more, the code does not support GPT partitions, which are becoming more popular, and maintaining device subsetting in both NBD and the raw device is unnecessary duplication of effort (even if it is not too difficult). Note that obtaining the offsets of a partition (MBR or GPT) can be learned by using 'qemu-nbd -c /dev/nbd0 file.qcow2 && sfdisk --dump /dev/nbd0', but by the time you've done that, you might as well just mount /dev/nbd0p1 that the kernel creates for you instead of bothering with qemu exporting a subset. Or, keeping to just user-space code, use nbdkit's partition filter, which has already known both GPT and primary MBR partitions for a while, and was just recently enhanced to support arbitrary logical MBR parititions. Start the clock on the deprecation cycle, with examples of how to accomplish device subsetting without using -P.

The tests tries to let qemu server mode to process the connection which turns out to be racy after commit 8258292e18c3 ("monitor: Remove "x-oob", offer capability "oob" unconditionally"). This is because the filter may try to mirror the packets before UNIX socket object is ready (connected was set to true) from the view of qemu. In this case the packet will be dropped silently. Fixing this by passing pre-connected socket created by socketpair() to qemu through fd.

2019-02-04xen: fix xen-bus state model to allow frontend re-connectionPaul Durrant
There is a flaw in the xen-bus state model. To allow a frontend to re- connect the backend state of an online XenDevice is transitioned from Closed to InitWait, but this is currently done unilaterally which is incorrect. The backend state should remain Closed until the frontend state transitions to Initialising. This patch removes the automatic backend state transition from xen_device_backend_state_changed() and, instead, adds an extra check in xen_device_frontend_state_changed() to determine whether a frontend is trying to re-connect to a previously Closed XenDevice. Only if this is found to be the case is the backend state transitioned from Closed to InitWait. Note that this transition will be common amongst all XenDevice classes and hence xen_device_frontend_state_changed() returns immediately afterwards without calling into the XenDeviceClass frontend_changed() method.

However, we still need to consider the underlying huge page size during munmap() because it requires that both address and length be a multiple of the underlying huge page size for Huge TLB mappings. Quote from "Huge page (Huge TLB) mappings" paragraph under NOTES section of the munmap(2) manual: "For munmap(), addr and length must both be a multiple of the underlying huge page size." On ppc64, the munmap() in qemu_ram_munmap() does not work for Huge TLB mappings because the mapped segment can be aligned with the underlying huge page size, not aligned with the native system page size, as returned by getpagesize(). This has the side effect of not releasing huge pages back to the pool after a hugetlbfs file-backed memory device is hot-unplugged. This patch fixes the situation in qemu_ram_mmap() and qemu_ram_munmap() by considering the underlying page size on ppc64. After this patch, memory hot-unplug releases huge pages back to the pool.

Unfold parts of qemu_ram_mmap() for the sake of understanding, moving declarations to the top, and keeping architecture-specifics in the ifdef-else blocks. No changes in the function behaviour.

2019-02-04spapr_pci: Fix endianness in assigned-addresses propertyAlexey Kardashevskiy
reg->phys_hi and assigned->phys_hi are big endian but we do an extra byteswap anyway when copying reg->phys_hi to assigned->phys_hi. To make things slightly more messy, we also add a relocatable bit (b_n()) although in the right endianness. This fixes endianness of assigned->phys_hi. This is unlikely to produce any visible difference though as we should end up there only in the case of PCI hotplug and even then I am not sure if (d->io_regions[i].addr == PCI_BAR_UNMAPPED) == true.

2019-02-04target/ppc: remove various HOST_WORDS_BIGENDIAN hacks in int_helper.cMark Cave-Ayland
Following on from the previous work, there are numerous endian-related hacks in int_helper.c that can now be replaced with Vsr* macros. There are also a few places where the VECTOR_FOR_INORDER_I macro can be replaced with a normal iterator since the processing order is irrelevant.

There is currently a "e500" machine section and a "ppce500" device section in the maintainers file - with some oddities: The wildcard in the device section also covers the files from the machine section.
