2016-12-22exec: introduce MemoryRegionCachePaolo Bonzini4-0/+251
Device models often have to perform multiple access to a single memory region that is known in advance, but would to use "DMA-style" functions instead of address_space_map/unmap. This can happen for example when the data has to undergo endianness conversion. Introduce a new data structure to cache the result of address_space_translate without forcing usage of a host address like address_space_map does. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-12-20Move target-* CPU file into a target/ folderThomas Huth369-80/+78
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-12-15virtio-pci: Fix cross-version migration with older machinesMaxime Coquelin3-1/+9
This patch fixes a cross-version migration regression introduced by commit d1b4259f ("virtio-bus: Plug devices after features are negotiated"). The problem is encountered when host's vhost backend does not support VIRTIO_F_VERSION_1, and migration is initiated from a v2.7 or prior machine with virtio-pci modern capabilities enabled to a v2.8 machine. In this case, modern capabilities get exposed to the guest by the source, whereas the target will detect version 1 is not supported so will only expose legacy capabilities. The problem is fixed by introducing a new "x-ignore-backend-features" property, which is set in v2.7 and prior compatibility modes. Doing this, v2.7 machine keeps its broken behaviour (enabling modern while version is not supported), and newer machines will behave correctly.

2016-12-06qapi: Document introduction of gluster's 'debug' optionEric Blake1-0/+1
We intentionally renamed 'debug-level' to 'debug' in the QMP schema for 'blockdev-add' related to gluster, in order to match the command line (commit 1a417e46). However, since 'debug-level' was visible in 2.7, that means that we should document that 'debug' was not available until 2.8. The change was intentional because 'blockdev-add' itself underwent incompatible changes (such as commit 0153d2f) for the same release; our intent is that after 2.8, these interfaces will now be stable.

2016-12-06exec.c: Fix breakpoint invalidation racePeter Maydell1-19/+6
A bug (1647683) was reported showing a crash when removing breakpoints. The reproducer was bisected to 3359baad when tb_flush was finally made thread safe. While in MTTCG the locking in breakpoint_invalidate would have prevented any problems, but currently tb_lock() is a NOP for system emulation. The race is between a tb_flush from the gdbstub and the tb_invalidate_phys_addr() in breakpoint_invalidate(). Ideally we'd have actual locking here; for the moment the simple fix is to do a full tb_flush() for a bp invalidate, since that is thread-safe even if no lock is taken.

2016-12-06qcow2: Don't strand clusters near 2G intervals during commitEric Blake3-83/+210
The qcow2_make_empty() function is reached during 'qemu-img commit', in order to clear out ALL clusters of an image. However, if the image cannot use the fast code path (true if the image is format 0.10, or if the image contains a snapshot), the cluster size is larger than 512, and the image is larger than 2G in size, then our choice of sector_step causes problems. Since it is not cluster aligned, but qcow2_discard_clusters() silently ignores an unaligned head or tail, we are leaving clusters allocated. Enhance the testsuite to expose the flaw, and patch the problem by ensuring our step size is aligned.

While testing rth's latest TCG patches with risu I found ldaxp was broken. Investigating further I found it was broken by 1dd089d0 when the cmpxchg atomic work was merged. As part of that change the code attempted to be clever by doing a single 64 bit load and then shuffle the data around to set the two 32 bit registers. As I couldn't quite follow the endian magic I've simply partially reverted the change to the original code gen_load_exclusive code. This doesn't affect the cmpxchg functionality as that is all done on in gen_store_exclusive part which is untouched. I've also restored the comment that was removed (with a slight tweak to mention cmpxchg).

2016-12-05tests: Avoid qobject_from_jsonf("%"PRId64)Eric Blake2-5/+6
The qobject_from_jsonf() function implements a pseudo-printf language for creating a QObject; however, it is hard-coded to only parse a subset of formats understood by -Wformat, and is not a straight synonym to bare printf(). In particular, any use of an int64_t integer works only if the system's definition of PRId64 matches what the parser expects; which works on glibc (%lld or %ld depending on 32- vs. 64-bit) and mingw (%I64d), but not on Mac OS (%qd). Rather than enhance the parser, it is just as easy to force the use of int (where the value is small enough) or long long instead of int64_t, which we know always works. This should cover all remaining testsuite uses of qobject_from_json[fv]() that were trying to rely on PRId64, although my proof for that was done by adding in asserts and checking that 'make check' still passed, where such asserts are inappropriate during hard freeze. A later series in 2.9 may remove all dynamic JSON parsing, but that's a bigger task.

The qobject_from_jsonv() function implements a pseudo-printf language for creating a QObject; however, it is hard-coded to only parse a subset of formats understood by -Wformat, and is not a straight synonym to bare printf(). In particular, any use of an int64_t integer works only if the system's definition of PRId64 matches what the parser expects; which works on glibc (%lld or %ld depending on 32- vs. 64-bit) and mingw (%I64d), but not on Mac OS (%qd). Rather than enhance the parser, it is just as easy to use normal printf() for this particular conversion, matching what is done elsewhere in this file [1], which is safe in this instance because the format does not contain any of the problematic differences (bare '%' or the '%s' format). The use of PRId64 for a variable named 'pid' is gross, but it is a sad reality of the 64-bit mingw environment, which mistakenly defines pid_t as a 64-bit type even though getpid() returns 'int' on that platform [2]. Our definition of the QGA GuestExec type defines 'pid' as a 64-bit entity, and we can't tighten it to 'int32' unless the mingw header is fixed. Using 'long long' instead of 'int64_t' just so that we can stick with qobject_from_jsonv("%lld") instead of printf() is not any prettier, since we may have later type churn anyways.

The qobject_from_jsonf() function implements a pseudo-printf language for creating a QObject; however, it is hard-coded to only parse a subset of formats understood by -Wformat, and is not a straight synonym to bare printf().

Rather than enhance the parser, it is just as easy to use 'long long', which we know always works. There are few enough callers of qobject_from_json[fv]() that it is easy to audit that this is the only non-testsuite caller that was actually relying on this particular conversion.

2016-12-05fsl_etsec: Pad short payloads with zerosAndrey Smirnov1-0/+8
Depending on QEMU network setup it is possible for us to receive a complete Ethernet packet that is less 64 bytes long. One such example is when QEMU is configured to use a standalone TAP device (not set to be a part of any bridge) receives and ARP packet. In cases like that we need to add more than just 4-bytes of CRC padding and ensure that our payload is at least 60 bytes long, such that, when combined with CRC padding bytes the resulting size is at least 802.3 minimum MTU bytes long (64). Failing to do that results in code in etsec_walk_rx_ring() setting BD_RX_SH which, in turn, makes corresponding Linux driver of emulated host to reject buffer as a runt packet Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

ColdFire Fast Ethernet Controller uses a receive buffer size register(EMRBR) to hold maximum size of all receive buffers. It is set by a user before any operation. If it was set to be zero, ColdFire emulator would go into an infinite loop while receiving data in mcf_fec_receive. Add check to avoid it.

2016-12-05qxl: Only emit QXL_INTERRUPT_CLIENT_MONITORS_CONFIG on config changesChristophe Fergeau1-1/+36
Currently if the client keeps sending the same monitor config to QEMU/spice-server, QEMU will always raise a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG regardless of whether there was a change or not. Guest-side (with fedora 25), the kernel QXL KMS driver will also forward the event to user-space without checking if there were actual changes. Next in line are gnome-shell/mutter (on a default f25 install), which will try to reconfigure everything without checking if there is anything to do. Where this gets ugly is that when applying the resolution changes, gnome-shell/mutter will call drmModeRmFB, drmModeAddFB, and drmModeSetCrtc, which will cause the primary surface to be destroyed and recreated by the QXL KMS driver. This in turn will cause the client to resend a client monitors config message, which will cause QEMU to reemit an interrupt with an unchanged monitors configuration, ... This causes https://bugzilla.redhat.com/show_bug.cgi?id=1266484 This commit makes sure that we only emit QXL_INTERRUPT_CLIENT_MONITORS_CONFIG when there are actual configuration changes the guest should act on.
