2015-06-19semihosting: add --semihosting-config arg sub-argumentLeon Alrae
Add new "arg" sub-argument to the --semihosting-config allowing the user to pass multiple input arguments separately. It is required for example by UHI semihosting to construct argc and argv. Also, update ARM semihosting to support new option (at the moment it is the only target which cares about arguments). If the semihosting is enabled and no semihosting args have been specified, then fall back to -kernel/-append. The -append string is split on whitespace before initializing semihosting.argv[1..n]; this is different from what QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole -append), but is more intuitive from UHI user's point of view and Linux kernel just does not care as it concatenates argv[1..n] into single cmdline string anyway.

2015-06-19semihosting: create SemihostingConfig structure and semihost.hLeon Alrae
Remove semihosting_enabled and semihosting_target and replace them with SemihostingConfig structure containing equivalent fields. The structure is defined in vl.c where it is actually set. Also introduce separate header file include/exec/semihost.h allowing to access semihosting config related stuff from target specific semihosting code.

2015-06-19vhost: enable vhost without without MSI-XPankaj Gupta
We use vhostforce to enable vhost even if Guests don't have MSI-X support and we fall back to QEMU virtio-net. This gives a very small performance gain, but the disadvantage is that guest now controls which virtio code is running (qemu or vhost) so our attack surface is doubled. This patch will enable vhost unconditionally whenever it's requested. For compatibility, enable vhost when vhostforce is set, as well.

2015-06-15linux-user: Allocate thunk size dynamicallyAlexander Graf
We store all struct types in an array of static size without ever checking whether we overrun it. Of course some day someone (like me in another, ancient ALSA enabling patch set) will run into the limit without realizing it. So let's make the allocation dynamic. We already know the number of structs that we want to allocate, so we only need to pass the variable into the respective piece of code. Also, to ensure we don't accidently overwrite random memory, add some asserts to sanity check whether a thunk is actually part of our array.

2015-06-12block: Add BlockDriverState.inherits_fromKevin Wolf
Currently, the block layer assumes that any block node can have only one parent, and if it has a parent, that it inherits some options/flags from this parent. This is not true any more: With references used in block device creation, a single node can be used by multiple parents, or it can be created separately and not inherit flags from any parent. To handle reopens correctly, a node must know from which parent it inherited options. This patch adds the information to BlockDriverState.

2015-06-12block: Add list of children to BlockDriverStateKevin Wolf
This allows iterating over all children of a given BDS, not only including bs->file and bs->backing_hd, but also driver-specific ones like VMDK extents or Quorum children. For bdrv_swap(), the list of children of the swapped BDS stays at that BDS (because that's where the pointers stay as well). The list head moves and pointers to it must be fixed up therefore. The list of children in the parent of the swapped BDS is not affected by the swap. The contents of the BDS objects is swapped, so the existing pointer in the parent automatically points to the newly swapped in BDS.

This counts the entries in a flattened array in a QDict without actually splitting the QDict into a QList. bdrv_open_image() doesn't take a QList, but rather a QDict and a key prefix string, so this is more convenient for block drivers which have a dynamically sized list of child nodes (e.g. Quorum) and are to be converted to using bdrv_open_image() as the standard interface for opening child nodes.

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.

2015-06-12migration: Use normal VMStateDescriptions for SubsectionsJuan Quintela
We create optional sections with this patch. But we already have optional subsections. Instead of having two mechanism that do the same, we can just generalize it. For subsections we just change: - Add a needed function to VMStateDescription - Remove VMStateSubsection (after removal of the needed function it is just a VMStateDescription) - Adjust the whole tree, moving the needed function to the corresponding VMStateDescription Signed-off-by: Juan Quintela <quintela@redhat.com>
