2017-08-08qemu-iotests/109: Fix lock race conditionCleber Rosa
A race condition is currently present between the clean up attempt of the QEMU process and the execution of qemu-img. The actual (bad) output is: -Warning: Image size mismatch! -Images are identical. +qemu-img: Could not open '<build_dir>/tests/qemu-iotests/scratch/t.raw': Failed to get "consistent read" lock +Is another process using the image? A KILL signal is sent to the QEMU process, but qemu-img may begin to run before the QEMU process is really gone. qemu-img will then attempt to open the TEST_IMG file before it can secure a lock on it. This attempts a more graceful shutdown, and waits for the QEMU process to exit.

2017-08-02target/mips: Use BS_EXCP where interrupts are expectedJames Hogan
Commit e350d8ca3ac7 ("target/mips: optimize indirect branches") made indirect branches able to directly find the next TB and jump straight to it without breaking out of translated code and going around the main execution loop. This breaks the assumption in target/mips/translate.c that BS_STOP is sufficient to cause pending interrupts to be handled, since interrupts are only checked in the main loop. Fix a few of these assumptions by using gen_save_pc to update the saved PC and using BS_EXCP instead of BS_STOP: - [D]MFC0 CP0_Count may trigger a timer interrupt which should be immediately handled. - [D]MTC0 CP0_Cause may trigger an interrupt (but in fact translation was only even being stopped in the DMTC0 case). - [D]MTC0 CP0_<any> when icount is used is assumed could potentially cause interrupts. - EI may trigger an interrupt which was pending. I specifically hit this case when running KVM nested in mipsel-softmmu. A timer interrupt while the 2nd guest was executing is caught by KVM which switches back to the normal Linux exception base and re-enables interrupts with EI. Since the above commit QEMU doesn't leave translated code until the nested KVM has already restored the KVM exception base and returned to the 2nd guest, at which point it is too late to check for pending interrupts and it gets stuck in an infinite loop of unhandled interrupts. Something similar was needed for ARM in commit b29fd33db578 ("target/arm: use DISAS_EXIT for eret handling").

2017-08-02mips: Add KVM T&E segment support for TCGJames Hogan
MIPS KVM trap & emulate guest kernels have a different segment layout compared with traditional MIPS kernels, to allow both the user and kernel code to run from the user address segment without repeatedly trapping to KVM. QEMU currently supports this layout only for KVM, but its sometimes useful to be able to run these kernels in QEMU on a PC, so enable it for TCG too. This also paves the way for MIPS KVM VZ support (which uses the normal virtual memory layout) by abstracting whether user mode kernel segments are in use.

2017-08-02mips: Improve segment defs for KVM T&E guestsJames Hogan
Improve the segment definitions used by get_physical_address() to yield target_ulong types, e.g. 0xffffffff80000000 instead of 0x80000000. This is in preparation for enabling emulation of MIPS KVM T&E segments in TCG MIPS targets, which unlike KVM could potentially have 64-bit target_ulong. In such a case the offset guest KSEG0 address ends up at e.g. 0x000000008xxxxxxx instead of 0xffffffff8xxxxxxx. This also allows the casts to int32_t that force sign extension to be removed, which removes any confusion due to relational comparison of unsigned (target_ulong) and signed (int32_t) types.

2017-08-02mips/malta: leave space for the bootmap after the initrdAurelien Jarno
Since commit 9768e2abf7 the initrd is loaded at the end of the low memory to avoid clash for the kernel relocation when kaslr is used. However this in turn conflicts with the bootmap memory that the kernel tries to place after initrd, but in low memory. The bootmap spans the whole usable physical address space. The machine can have at most 2GiB of memory, 256MiB of low memory mapped at 0x00000000, and 1792MiB of high memory mapped at 0x90000000. The biggest bootmap therefore corresponds to the adresses 0x00000000 -> 0xffffffff, which at 1 bit per 4kiB page corresponds to 128kiB in memory. Therefore reserve 128kiB after the initrd.

2017-08-02io: fix qio_channel_socket_accept err handlingPeter Xu
When accept failed, we should setup errp with the reason. More importantly, the caller may assume errp be non-NULL when error happens, and not setting the errp may crash QEMU. At the same time, move the trace_qio_channel_socket_accept_fail() after the if check on EINTR. Two reasons: 1. when EINTR happened, it's not really a fault (we should just try again), so we should not log with an "accept failure". 2. trace_*() functions may overwrite errno, then the old errno will be missing. We need to either check errno before trace_*() calls, or reserve the errno.

2017-08-02pc: acpi: force FADT rev1 for 440fx based machine typesIgor Mammedov
w2k used to boot on QEMU until revision of FADT has been bumped to rev3 (commit 77af8a2b hw/i386: Use Rev3 FADT (ACPI 2.0) instead of Rev1 to improve guest OS support.) Keep PC machine at rev1 to remain compatible and Q35 at rev3 where w2k isn't supported anyway so OSX could run as well.

2017-08-02pc: make 'pc.rom' readonly when machine has PCI enabledIgor Mammedov
looking at bios ROM mapping in QEMU it seems that only isapc (i.e. not PCI enabled machine) requires ROM being mapped as RW in other cases BIOS is mapped as RO. Do the same for option ROM 'pc.rom' when machine has PCI enabled. As useful side-effect pc.rom MemoryRegion stops being put in vhost memory map (filtered out by vhost_section()), which reduces number of entries by 1. Coincidentally it fixes migration failure reported in "[PATCH V2] vhost: fix a migration failed because of vhost region merge" where following destination CLI with /sys/module/vhost/parameters/max_mem_regions = 8 export DIMMSCOUNT=6 QEMU -enable-kvm \ -netdev type=tap,id=guest0,vhost=on,script=no,vhostforce \ -device virtio-net-pci,netdev=guest0 \ -m 256,slots=256,maxmem=2G \ `i=0; while [ $i -lt $DIMMSCOUNT ]; do echo \ "-object memory-backend-ram,id=m$i,size=128M \ -device pc-dimm,id=d$i,memdev=m$i"; i=$(($i + 1)); \ done` will fail to startup with error: "-device pc-dimm,id=d5,memdev=m5: a used vhost backend has no free memory slots left" while it's possible to add the 6th DIMM during hotplug on source. Issue is caused by the fact that number of entries in vhost map is bigger on 1 entry, when -device is processed, than after guest boots up, and that offending entry belongs to 'pc.rom', it's not like vhost intends to do IO in ROM range so making it RO hides region from vhost and makes number of entries in vhost memory map at -device/machine_done time match number of entries after guest boots.

2017-08-02vhost-user: fix legacy cross-endian configurationsFelipe Franciosi
Currently, vhost-user does not implement any means for notifying the backend about guest endianess. This commit introduces a new message called VHOST_USER_SET_VRING_ENDIAN which is analogous to the ioctl() called VHOST_SET_VRING_ENDIAN used for kernel vhost backends. Such message is necessary for backends supporting legacy (pre-1.0) virtio devices running in big-endian guests.

When skipping implicit nodes in bdrv_block_device_info(), we know that bs0 is always non-NULL; initially, because it's taken from a BdrvChild and a BdrvChild never has a NULL bs, and after the first iteration because implicit nodes always have a backing file. Remove the NULL check and add an assertion that the implicit node does indeed have a backing file.

2017-08-01qemu-iotests/059: Fix leaked image filesKevin Wolf
qemu-iotests 059 left a whole lot of image files behind in the scratch directory because VMDK creates additional files for extents and cleaning them up requires the original image intact (it parses qemu-img info output to find all extent files), but the image overwrote it many times like it works for all other image formats. In addition, _use_sample_img overwrites the TEST_IMG variable, causing new images created afterwards to reuse the name of the sample file rather than the usual t.IMGFMT. This patch adds an intermediate _cleanup_test_img after each subtest that created an image file with additional extent files, and also after each use of a sample image. _cleanup_test_img is also changed so that it resets TEST_IMG after a sample image is cleaned up. Note that this test was failing before this commit and continues to do so after it. This failure was introduced in commit 9877860 ('block/vmdk: Report failures in vmdk_read_cid()') and needs to be dealt with separately.
