2016-02-04net/filter: Fix the output information for command 'info network'zhanghailiang
The properties of netfilter object could be changed by 'qom-set' command, but the output of 'info network' command is not updated, because it got the old information through nf->info_str, it will not be updated while we change the value of netfilter's property. Here we split a helper function that could collect the output information for filter, and also remove the useless member 'info_str' from struct NetFilterState.

2016-02-04net: always walk through filters in reverse if traffic is egressLi Zhijian
Previously, if we attach more than one filters for a single netdev, both ingress and egress traffic will go through net filters in same order like: ingress: netdev ->filter1 ->filter2 ->...filter[n] ->emulated device egress: emulated device ->filter1 ->filter2 ->...filter[n] ->netdev. This is against the natural feeling and will complicate filters configuration since in some scenes, we hope filters handle the egress traffic in a reverse order. For example, in colo-proxy (will be implemented later), we have a redirector filter and a colo-rewriter filter, we need the filter behave like: ingress(->)/egress(<-): chardev<->redirector<->colo-rewriter<->emulated device Since both buffer filter and dump do not require strict order of filters, this patch switches to always let egress traffic walk through net filters in reverse to simplify the possible filters configuration in the future.

2016-02-02block: set device_list.tqe_prev to NULL on BDS removalJeff Cody
This fixes a regression introduced with commit 3f09bfbc7. Multiple bugs arise in conjunction with live snapshots and mirroring operations (which include active layer commit). After a live snapshot occurs, the active layer and the base layer both have a non-NULL tqe_prev field in the device_list, although the base node's tqe_prev field points to a NULL entry. This non-NULL tqe_prev field occurs after the bdrv_append() in the external snapshot calls change_parent_backing_link(). In change_parent_backing_link(), when the previous active layer is removed from device_list, the device_list.tqe_prev pointer is not set to NULL. The operating scheme in the block layer is to indicate that a BDS belongs in the bdrv_states device_list iff the device_list.tqe_prev pointer is non-NULL. This patch does two things: 1.) Introduces a new block layer helper bdrv_device_remove() to remove a BDS from the device_list, and 2.) uses that new API, which also fixes the regression once used in change_parent_backing_link().

Until block drivers fill in the right value, let's clear it explicitly right before calling .bdrv_get_block_status. The "bs->file" condition in bdrv_co_get_block_status is kept now to keep iotest case 102 passing, and will be fixed once all drivers return the right file pointer.

When bdrv_close_all() is called, instead of force-closing all root BlockDriverStates, it is better to just drop the reference from all BlockBackends and let them be closed automatically. This prevents BDS from getting closed that are still referenced by other BDS, which may result in loss of cached data.

2016-01-27gdb: provide the name of the architecture in the target.xmlDavid Hildenbrand
This patch provides the name of the architecture in the target.xml if available. This allows the remote gdb to detect the target architecture on its own - so there is no need to specify it manually (e.g. if gdb is started without a binary) using "set arch *arch_name*". The name of the architecture is provided by a callback that can be implemented by all architectures. The arm implementation has special handling for iwmmxt and returns arm otherwise. This can be extended if necessary.

2016-01-26xen: make it possible to build without the Xen PV domain builderIan Campbell
Until the previous patch this relied on xc_fd(), which was only implemented for Xen 4.0 and earlier. Given this wasn't working since Xen 4.0 I have marked this as disabled by default. Removing this support drops the use of a bunch of symbols from libxenctrl, specifically: - xc_domain_create - xc_domain_destroy - xc_domain_getinfo - xc_domain_max_vcpus - xc_domain_setmaxmem - xc_domain_unpause - xc_evtchn_alloc_unbound - xc_linux_build This is another step towards only using Xen libraries which provide a stable inteface.

2016-01-26xen: domainbuild: reopen libxenctrl interface after forking for domain watcher.Ian Campbell
Using an existing libxenctrl handle after a fork was never particularly safe (especially if foreign mappings existed at the time of the fork) and the xc fd has been unavailable for many releases. Reopen the handle after fork and therefore do away with xc_fd().

2016-01-26xen: Use stable library interfaces when they are available.Ian Campbell
In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. Specifically libxenevtchn, libxengnttab and libxenforeignmemory. Previous patches have already laid the groundwork for using these by switching the existing compatibility shims to reflect the intefaces to these libraries. So all which remains is to update configure to detect the libraries and enable their use. Although they are notionally independent we take an all or nothing approach to the three libraries since they were added at the same time. The only non-obvious bit is that we now open a proper xenforeignmemory handle for xen_fmem instead of reusing the xen_xc handle. Build tested with 4.0 .. 4.6 (inclusive) and the patches targetting 4.7 which adds these libraries. This uses CONFIG_XEN_CTRL_INTERFACE_VERSION == 471 to cover the introduction of these new interfaces.

2016-01-26xen: Switch uses of xc_map_foreign_{pages,bulk} to use libxenforeignmemory API.Ian Campbell
In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. One such library will be libxenforeignmemory which provides access to privileged foreign mappings and which will provide an interface equivalent to xc_map_foreign_{pages,bulk}. The new xenforeignmemory_map() function behaves like xc_map_foreign_pages() when the err argument is NULL and like xc_map_foreign_bulk() when err is non-NULL, which maps into the shim here onto checking err == NULL and calling the appropriate old function. Note that xenforeignmemory_map() takes the number of pages before the arrays themselves, in order to support potentially future use of variable-length-arrays in the prototype (in the future, when Xen's baseline toolchain requirements are new enough to ensure VLAs are supported). In preparation for adding support for libxenforeignmemory add support to the <=4.0 and <=4.6 compat code in xen_common.h to allow us to switch to using the new API. These shims will disappear for versions of Xen which include libxenforeignmemory. Since libxenforeignmemory will have its own handle type but for <= 4.6 the functionality is provided by using a libxenctrl handle we introduce a new global xen_fmem alongside the existing xen_xc. In fact we make xen_fmem a pointer to the existing xen_xc, which then works correctly with both <=4.0 (xc handle is an int) and <=4.6 (xc handle is a pointer). In the latter case xen_fmem is actually a double indirect pointer, but it all falls out in the wash. Unlike libxenctrl libxenforeignmemory has an explicit unmap function, rather than just specifying that munmap should be used, so the unmap paths are updated to use xenforeignmemory_unmap, which is a shim for munmap on these versions of xen. The mappings in xen-hvm.c do not appear to be unmapped (which makes sense for a qemu-dm process) In fb_disconnect this results in a change from simply mmap over the existing mapping (with an implicit munmap) to expliclty unmapping with xenforeignmemory_unmap and then mapping the required anonymous memory in the same hole. I don't think this is a problem since any other thread which was racily touching this region would already be running the risk of hitting the mapping halfway through the call. If this is thought to be a problem then we could consider adding an extra API to the libxenforeignmemory interface to replace a foreign mapping with anonymous shared memory, but I'd prefer not to.
