Coverity reports that when we're assigning vi->size we handle the "pmem->memdev is NULL" case; but we then pass it into object_get_canonical_path(), which unconditionally dereferences it and will crash if it is NULL.

2019-07-12virtio-balloon: fix QEMU 4.0 config size migration incompatibilityStefan Hajnoczi
The virtio-balloon config size changed in QEMU 4.0 even for existing machine types. Migration from QEMU 3.1 to 4.0 can fail in some circumstances with the following error: qemu-system-x86_64: get_pci_config_device: Bad config data: i=0x10 read: a1 device: 1 cmask: ff wmask: c0 w1cmask:0 This happens because the virtio-balloon config size affects the VIRTIO Legacy I/O Memory PCI BAR size. Introduce a qdev property called "qemu-4-0-config-size" and enable it only for the QEMU 4.0 machine types. This way <4.0 machine types use the old size, 4.0 uses the larger size, and >4.0 machine types use the appropriate size depending on enabled virtio-balloon features. Live migration to and from old QEMUs to QEMU 4.1 works again as long as a versioned machine type is specified (do not use just "pc"!).

2019-07-12file-posix: Use max transfer length/segment count only for SCSI passthroughMaxim Levitsky
Regular kernel block devices (/dev/sda*, /dev/nvme*, etc) don't have max segment size/max segment count hardware requirements exposed to the userspace, but rather the kernel block layer takes care to split the incoming requests that violate these requirements. Allowing the kernel to do the splitting allows qemu to avoid various overheads that arise otherwise from this. This is especially visible in nbd server, exposing as a raw file, a mostly empty qcow2 image over the net. In this case most of the reads by the remote user won't even hit the underlying kernel block device, and therefore most of the overhead will be in the nbd traffic which increases significantly with lower max transfer size. In addition to that even for local block device access the peformance improves a bit due to less traffic between qemu and the kernel when large transfer sizes are used (e.g for image conversion) More info can be found at: https://bugzilla.redhat.com/show_bug.cgi?id=1647104 Signed-off-by: Maxim Levitsky <mlevitsk@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Pankaj Gupta <pagupta@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2019-07-12xics/kvm: Always set the MASKED bit if interrupt is maskedGreg Kurz
The ics_set_kvm_state_one() function is called either to restore the state of an interrupt source during migration or to set the interrupt source to a default state during reset. Since always, ie. 2013, the code only sets the MASKED bit if the 'current priority' and the 'saved priority' are different. This is likely true when restoring an interrupt that had been previously masked with the ibm,int-off RTAS call. However this is always false in the case of reset since both 'current priority' and 'saved priority' are equal to 0xff, and the MASKED bit is never set. The legacy KVM XICS device gets away with that because it ends updating its internal structure the same way, whether the MASKED bit is set or the priority is 0xff. The XICS-on-XIVE device for POWER9 is different. It sticks to the KVM documentation [1] and _really_ relies on the MASKED bit to correctly set. If not, it will configure the interrupt source in the XIVE HW, even though the guest hasn't configured the interrupt yet. This disturbs the complex logic implemented in XICS-on-XIVE and may result in the loss of subsequent queued events. Always set the MASKED bit if interrupt is masked as expected by the KVM XICS-on-XIVE device. This has no impact on the legacy KVM XICS.

2019-07-10docs/bitmaps: use QMP lexer instead of jsonJohn Snow
The annotated style json we use in QMP documentation is not strict json and depending on the version of Sphinx (2.0+) or Pygments installed, might cause the build to fail. Use the new QMP lexer. Further, some versions of Sphinx can not apply custom lexers to "code" directives and require the use of "code-block" directives instead, so make that change at this time as well. Tested under: - Sphinx 1.3.6 and Pygments 2.4 - Sphinx 1.7.6 and Pygments 2.2 (Fedora 29 packages) - Sphinx 2.0.1 and Pygments 2.4 - Sphinx 3.0.0+/f396b3a783 and Pygments 2.4 (From Sphinx git c4f44bdd) Reported-by: Aarushi Mehta <mehta.aaru20@gmail.com> Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> Message-id: 20190603214653.29369-4-jsnow@redhat.com Signed-off-by: John Snow <jsnow@redhat.com>
2019-07-10sphinx: add qmp_lexerJohn Snow
Sphinx, through Pygments, does not like annotated json examples very much. In some versions of Sphinx (1.7), it will render the non-json portions of code blocks in red, but in newer versions (2.0) it will throw an exception and not highlight the block at all. Though we can suppress this warning, it doesn't bring back highlighting on non-strict json blocks. We can alleviate this by creating a custom lexer for QMP examples that allows us to properly highlight these examples in a robust way, keeping our directionality and elision notations.

2019-07-09Revert "hw/block/pflash_cfi02: Reduce I/O accesses to 16-bit"Philippe Mathieu-Daudé
This reverts commit 3ae0343db69c379beb5750b4ed70794bbed51b85. Stephen Checkoway noticed commit 3ae0343db69 is incorrect. This commit state all parallel flashes are limited to 16-bit accesses, however the x32 configuration exists in some models, such the Cypress S29CL032J, which CFI Device Geometry Definition announces: CFI ADDR DATA 0x28,0x29 = 0x0003 (x32-only asynchronous interface) Guests should not be affected by the previous change, because QEMU does not announce itself as x32 capable: /* Flash device interface (8 & 16 bits) */ pfl->cfi_table[0x28] = 0x02; pfl->cfi_table[0x29] = 0x00; Commit 3ae0343db69 does not restrict the bus to 16-bit accesses, but restrict the implementation as 16-bit access max, so a guest 32-bit access will result in 2x 16-bit calls. Now, we have 2 boards that register the flash device in 32-bit access: - PPC: taihu_405ep The CFI id matches the S29AL008J that is a 1MB in x16, while the code QEMU forces it to be 2MB, and checking Linux it expects a 4MB flash. - ARM: Digic4 While the comment says "Samsung K8P3215UQB 64M Bit (4Mx16)", this flash is 32Mb (2MB). Also note the CFI id does not match the comment. To avoid unexpected side effect, we revert commit 3ae0343db69, and will clean the board code later.

2019-07-08virtio-scsi: restart DMA after iothreadStefan Hajnoczi
When the 'cont' command resumes guest execution the vm change state handlers are invoked. Unfortunately there is no explicit ordering between classic qemu_add_vm_change_state_handler() callbacks. When two layers of code both use vm change state handlers, we don't control which handler runs first. virtio-scsi with iothreads hits a deadlock when a failed SCSI command is restarted and completes before the iothread is re-initialized. This patch uses the new qdev_add_vm_change_state_handler() API to guarantee that virtio-scsi's virtio change state handler executes before the SCSI bus children. This way DMA is restarted after the iothread has re-initialized. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2019-07-08hw/arm/sbsa-ref: Remove unnecessary check for secure_sysmem == NULLPeter Maydell
In the virt machine, we support TrustZone being either present or absent, and so the code must deal with the secure_sysmem pointer possibly being NULL. In the sbsa-ref machine, TrustZone is always present, but some code and comments copied from virt still treat it as possibly not being present. This causes Coverity to complain (CID 1407287) that we check secure_sysmem for being NULL after an unconditional dereference. Simplify the code so that instead of initializing the variable to NULL, unconditionally assigning it, and then testing it for NULL, we just initialize it correctly in the variable declaration and then assume it to be non-NULL. We also delete a comment which only applied to the non-TrustZone config.

2019-07-08tests/migration-test: Fix read off end of aarch64_kernel arrayPeter Maydell
The test aarch64 kernel is in an array defined with unsigned char aarch64_kernel[] = { [...] } which means it could be any size; currently it's quite small. However we write it to a file using init_bootfile(), which writes exactly 512 bytes to the file. This will break if we ever end up with a kernel larger than that, and will read garbage off the end of the array in the current setup where the kernel is smaller. Make init_bootfile() take an argument giving the length of the data to write. This allows us to use it for all architectures (previously s390 had a special-purpose init_bootfile_s390x which hardcoded the file to write so it could write the correct length). We assert that the x86 bootfile really is exactly 512 bytes as it should be (and as we were previously just assuming it was). This was detected by the clang-7 asan: ==15607==ERROR: AddressSanitizer: global-buffer-overflow on address 0x55a796f51d20 at pc 0x55a796b89c2f bp 0x7ffc58e89160 sp 0x7ffc58e88908 READ of size 512 at 0x55a796f51d20 thread T0 #0 0x55a796b89c2e in fwrite (/home/petmay01/linaro/qemu-from-laptop/qemu/build/sanitizers/tests/migration-test+0xb0c2e) #1 0x55a796c46492 in init_bootfile /home/petmay01/linaro/qemu-from-laptop/qemu/tests/migration-test.c:99:5 #2 0x55a796c46492 in test_migrate_start /home/petmay01/linaro/qemu-from-laptop/qemu/tests/migration-test.c:593 #3 0x55a796c44101 in test_baddest /home/petmay01/linaro/qemu-from-laptop/qemu/tests/migration-test.c:854:9 #4 0x7f906ffd3cc9 (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x72cc9) #5 0x7f906ffd3bfa (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x72bfa) #6 0x7f906ffd3bfa (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x72bfa) #7 0x7f906ffd3ea1 in g_test_run_suite (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x72ea1) #8 0x7f906ffd3ec0 in g_test_run (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x72ec0) #9 0x55a796c43707 in main /home/petmay01/linaro/qemu-from-laptop/qemu/tests/migration-test.c:1187:11 #10 0x7f906e9abb96 in __libc_start_main /build/glibc-OTsEL5/glibc-2.27/csu/../csu/libc-start.c:310 #11 0x55a796b6c2d9 in _start (/home/petmay01/linaro/qemu-from-laptop/qemu/build/sanitizers/tests/migration-test+0x932d9) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Laurent Vivier <lvivier@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-id: 20190702150311.20467-1-peter.maydell@linaro.org

2019-07-08s390x/cpumodel: Set up CPU model for AQIC interceptionPierre Morel
Let's add support for the AP-Queue interruption facility to the CPU model. The S390_FEAT_AP_QUEUE_INTERRUPT_CONTROL, CPU facility indicates whether the PQAP instruction with the AQIC command is available to the guest. This feature will be enabled only if the AP instructions are available on the linux host and AQIC facility is installed on the host. This feature must be turned on from userspace to intercept AP instructions on the KVM guest. The QEMU command line to turn this feature on looks something like this: qemu-system-s390x ... -cpu xxx,apqi=on ... or ... -cpu host Right now AP pass-through devices do not support migration, which means that we do not have to take care of migrating the interrupt data: virsh migrate apguest --live qemu+ssh://root@target.lan/system error: Requested operation is not valid: domain has assigned non-USB host devices Signed-off-by: Pierre Morel <pmorel@linux.ibm.com> Reviewed-by: Tony Krowiak <akrowiak@linux.ibm.com> Reviewed-by: Christian Borntraeger <borntraeger@de.ibm.com> Reviewed-by: Halil Pasic <pasic@linux.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> [rebase to newest qemu and fixup description] Message-Id: <20190705153249.12525-1-borntraeger@de.ibm.com> Signed-off-by: Cornelia Huck <cohuck@redhat.com>
