2018-05-18xen/pt: use address_space_memory object for memory region hooksIgor Druzhinin1-1/+1
Commit 99605175c (xen-pt: Fix PCI devices re-attach failed) introduced a subtle bug. As soon as the guest switches off Bus Mastering on the device it immediately causes all the BARs be unmapped due to the DMA address space of the device being changed. This is undesired behavior because the guest may try to communicate with the device after that which triggers the following errors in the logs: [00:05.0] xen_pt_bar_read: Error: Should not read BAR through QEMU. @0x0000000000000200 [00:05.0] xen_pt_bar_write: Error: Should not write BAR through QEMU. @0x0000000000000200 The issue that the original patch tried to workaround (uneven number of region_add/del calls on device attach/detach) was fixed in d25836cafd (memory: do explicit cleanup when remove listeners).

2018-05-18xen-pvdevice: Introduce a simplistic xen-pvdevice save stateIgor Druzhinin1-0/+11
This should help to avoid problems with accessing the device after migration/resume without PV drivers by migrating its PCI configuration space state. Without an explicitly defined state record it resets every time a VM migrates which confuses the OS and makes every access to xen-pvdevice MMIO region to fail. PV tools enable some logic to save and restore PCI configuration state from within the VM every time it migrates which basically hides the issue. Older systems will acquire the new record when migrated which should not change their state for worse.

Coverity complains about use of uninitialized Evt struct. The EVT_SET_TYPE and similar setters use deposit32() on fields in the struct, so they read the uninitialized existing values. In cases where we don't set all the fields in the event struct we'll end up leaking random uninitialized data from QEMU's stack into the guest. Initializing the struct with "Evt evt = {};" ought to satisfy Coverity and fix the data leak.

The current code was not correctly handling 64 B (Max USB 1.1 payload size) packets and therefore preventing some of the messages from smart card to pass through to the guest. If the smart card in host responded with 34 B of data in APDU layer, the CCID headers added up to 64 B. The packet was send, but not correctly committed per USB specification (8.5.3.2 Variable-length Data Stage): > When all of the data structure is returned to the host, the function > should indicate that the Data stage is ended by returning a packet > that is shorter than the MaxPacketSize for the pipe. If the data > structure is an exact multiple of wMaxPacketSize for the pipe, the > function will return a zero-length packet to indicate the end of the > Data stage. This lead the guest applications to timeout while waiting for the rest of data (the emulation layer is answering with NAK until the timeout). This patch is checking the current maximum packet size and if the payload of this size is detected, the message buffer is not yet released. With the next call, the empty buffer is sent and the message buffer is finally released.

Since cc847bfd16d894fd8c1a2ce25f31772f6cdbbc74, CCID card-passthru fails to intialize, because it changed a debug line to an error, probably by mistake. Change it back to a DPRINTF debug.

2018-05-18sdl: Move use of surface pointer below check for whether it is NULLPeter Maydell1-3/+3
In commit 2ab858c6c38ee1 we added a use of the 'surf' variable in sdl2_2d_update() that was unfortunately placed above the early-exit-if-NULL check. Move it to where it ought to be.

2018-05-18console: Avoid segfault in screendumpMichal Privoznik1-0/+5
After f771c5440e04626f1 it is possible to select device and head which to take screendump from. And even though we check if provided head number falls within range, it may still happen that the console has no surface yet leading to SIGSEGV: qemu.git $ ./x86_64-softmmu/qemu-system-x86_64 \ -qmp stdio \ -device virtio-vga,id=video0,max_outputs=4 {"execute":"qmp_capabilities"} {"execute":"screendump", "arguments":{"filename":"/tmp/screen.ppm", "device":"video0", "head":1}} Segmentation fault #0 0x00005628249dda88 in ppm_save (filename=0x56282826cbc0 "/tmp/screen.ppm", ds=0x0, errp=0x7fff52a6fae0) at ui/console.c:304 #1 0x00005628249ddd9b in qmp_screendump (filename=0x56282826cbc0 "/tmp/screen.ppm", has_device=true, device=0x5628276902d0 "video0", has_head=true, head=1, errp=0x7fff52a6fae0) at ui/console.c:375 #2 0x00005628247740df in qmp_marshal_screendump (args=0x562828265e00, ret=0x7fff52a6fb68, errp=0x7fff52a6fb60) at qapi/qapi-commands-ui.c:110 Here, @ds from frame #0 (or @surface from frame #1) is dereferenced at the very beginning of ppm_save().

2018-05-17fpu/softfloat: Define floatN_silence_nan in terms of parts_silence_nanRichard Henderson2-77/+35
Isolate the target-specific choice to 3 functions instead of 6. The code in floatx80_default_nan tried to be over-general. There are only two targets that support this format: x86 and m68k. Thus there is no point in inventing a mechanism for snan_bit_is_one. Move routines that no longer have ifdefs out of softfloat-specialize.h.

2018-05-17fpu/softfloat: Define floatN_default_nan in terms of parts_default_nanRichard Henderson2-99/+47
Isolate the target-specific choice to 2 functions instead of 6. The code in float16_default_nan was only correct for ARM, MIPS, and X86. Though float16 support is rare among our targets. The code in float128_default_nan was arguably wrong for Sparc. While QEMU supports the Sparc 128-bit insns, no real cpu enables it. The code in floatx80_default_nan tried to be over-general. There are only two targets that support this format: x86 and m68k. Thus there is no point in inventing a value for snan_bit_is_one.
