2015-02-05migration: Append JSON description of migration streamAlexander Graf
One of the annoyances of the current migration format is the fact that it's not self-describing. In fact, it's not properly describing at all. Some code randomly scattered throughout QEMU elaborates roughly how to read and write a stream of bytes. We discussed an idea during KVM Forum 2013 to add a JSON description of the migration protocol itself to the migration stream. This patch adds a section after the VM_END migration end marker that contains description data on what the device sections of the stream are composed of. This approach is backwards compatible with any QEMU version reading the stream, because QEMU just stops reading after the VM_END marker and ignores any data following it. With an additional external program this allows us to decipher the contents of any migration stream and hopefully make migration bugs easier to track down.

2015-02-05qemu-file: Add fast ftell code pathAlexander Graf
For ftell we flush the output buffer to ensure that we don't have anything lingering in our internal buffers. This is a very safe thing to do. However, with the dynamic size measurement that the dynamic vmstate description will bring this would turn out quite slow. Instead, we can fast path this specific measurement and just take the internal buffers into account when telling the kernel our position. I'm sure I overlooked some corner cases where this doesn't work, so instead of tuning the safe, existing version, this patch adds a fast variant of ftell that gets used by the dynamic vmstate description code which isn't critical when it fails.

2015-02-05QJSON: Add JSON writerAlexander Graf
To support programmatic JSON assembly while keeping the code that generates it readable, this patch introduces a simple JSON writer. It emits JSON serially into a buffer in memory. The nice thing about this writer is its simplicity and low memory overhead. Unlike the QMP JSON writer, this one does not need to spawn QObjects for every element it wants to represent. This is a prerequisite for the migration stream format description generator.

2015-02-02rcu: add rcu libraryPaolo Bonzini
This includes a (mangled) copy of the liburcu code. The main changes are: 1) removing dependencies on many other header files in liburcu; 2) removing for simplicity the tentative busy waiting in synchronize_rcu, which has limited performance effects; 3) replacing futexes in synchronize_rcu with QemuEvents for Win32 portability. The API is the same as liburcu, so it should be possible in the future to require liburcu on POSIX systems for example and use our copy only on Windows. Among the various versions available I chose urcu-mb, which is the least invasive implementation even though it does not have the fastest rcu_read_{lock,unlock} implementation. The urcu flavor can be changed later, after benchmarking. Reviewed-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

These can be disabled via the cmdline: ... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1 Note: some guests can fake hibernation by writing a hibernate image and doing a shutdown instead of S4 if S4 isn't available; there's nothing we can do guests to stop doing this, and this patch can't affect that functionality.

The string field entries 'filename', 'backing_file', and 'exact_filename' in the BlockDriverState struct are defined as 1024 bytes. However, many places that use these values accept a maximum of PATH_MAX bytes, so we have a mixture of 1024 byte and PATH_MAX byte allocations. This patch makes the BlockDriverStruct field string sizes match usage. This patch also does a few fixes related to the size that needs to happen now: * the block qapi driver is updated to use PATH_MAX bytes * the qcow and qcow2 drivers have an additional safety check * the block vvfat driver is updated to use PATH_MAX bytes for the size of backing_file, for systems where PATH_MAX is < 1024 bytes. * qemu-img uses PATH_MAX rather than 1024. These instances were not changed to be dynamically allocated, however, as the extra temporary 3K in stack usage for qemu-img does not seem worrisome.

2015-01-20cpu_ldst_template.h: Drop unused cpu_ldfq/stfq/ldfl/stfl accessorsPeter Maydell
The cpu_ldfq/stfq/ldfl/stfl accessors for loading and storing float32 and float64 are completely unused, so delete them. (The union they use for converting from the float32/float64 type to uint32_t or uint64_t is the wrong way to do it anyway: they should be using make_float* and float*_val.)

2015-01-20cpu_ldst_template.h: Use ld*_p directly rather than via ld*_raw macrosPeter Maydell
The ld*_raw and st*_raw macros are now only used within the code produced by cpu_ldst_template.h, and only in three places. Expand these out to just call the ld_p and st_p functions directly. Note that in all the callsites the address argument is a uintptr_t, so we can drop that part of the double-cast used in the saddr() and laddr() macros.

2015-01-20cpu_ldst.h: Use inline functions for usermode cpu_ld/st accessorsPeter Maydell
Use inline functions rather than macros for cpu_ld/st accessors for the *-user configurations, as we already do for softmmu. This has a two advantages: * we can actually typecheck our arguments * we don't need to leak the _raw macros everywhere Since the _kernel functions were only used by target-i386/seg_helper.c, put the definitions for them in that file too. (It already has the similar template include code to define them for the softmmu case, so it makes sense to have it deal with defining them for user-only.)

The five ldul_ macros are not used anywhere and are marked up with an XXX comment. "ldul" is a non-standard prefix for our family of load instructions: we don't mark 32-bit accesses for signedness because they return a 32 bit quantity. So just delete them.

2015-01-20Xen: Use the ioreq-server API when availablePaul Durrant
The ioreq-server API added to Xen 4.5 offers better security than the existing Xen/QEMU interface because the shared pages that are used to pass emulation request/results back and forth are removed from the guest's memory space before any requests are serviced. This prevents the guest from mapping these pages (they are in a well known location) and attempting to attack QEMU by synthesizing its own request structures. Hence, this patch modifies configure to detect whether the API is available, and adds the necessary code to use the API if it is.
