2019-08-21spapr/xive: Mask the EAS when allocating an IRQCédric Le Goater1-1/+4
If an IRQ is allocated and not configured, such as a MSI requested by a PCI driver, it can be saved in its default state and possibly later on restored using the same state. If not initially MASKED, KVM will try to find a matching priority/target tuple for the interrupt and fail to restore the VM because 0/0 is not a valid target. When allocating a IRQ number, the EAS should be set to a sane default : VALID and MASKED.

2019-08-21spapr: Implement better workaround in spapr-vty devicePaul Mackerras1-18/+12
Linux guest kernels have code which scans the string of characters returned from the H_GET_TERM_CHAR hypercall and removes any \0 character which comes immediately after a \r character. This is to work around a bug which was present in some ancient versions of PowerVM. In order to avoid the corruption of the console byte stream that this introduced, commit 6c3bc244d3cb ("spapr: Implement bug in spapr-vty device to be compatible with PowerVM") added a workaround which adds a \0 character after every \r character. Unfortunately, this corrupts the console byte stream for those operating systems, such as AIX, which don't remove the null bytes. We can avoid triggering the Linux kernel workaround if we avoid returning a buffer which contains a \0 after a \r. We can do that by breaking out of the loop in vty_getchars() if we are about to insert a \0 and the previous character in the buffer is a \r. That means we return the characters up to the \r for the current H_GET_TERM_CHAR, and the characters starting with the \0 for the next one. With this workaround, we don't insert any spurious characters and we avoid triggering the Linux kernel workaround, so the guest will receive an uncorrupted stream whether or not they have the workaround.

2019-08-21spapr/pci: Free MSIs during resetGreg Kurz1-0/+2

When freeing MSIs, we need to: - remove them from the machine's MSI bitmap - remove them from the IC backend - remove them from the PHB's MSI cache This is currently open coded in two places in rtas_ibm_change_msi(), and we're about to need this in spapr_phb_reset() as well. Instead of duplicating this code again, make it a destroy function for the PHB's MSI cache. Removing an MSI device from the cache will call the destroy function internally.

2019-08-21spapr: initial implementation for H_TPM_COMM/spapr-tpm-proxyMichael Roth5-1/+228
This implements the H_TPM_COMM hypercall, which is used by an Ultravisor to pass TPM commands directly to the host's TPM device, or a TPM Resource Manager associated with the device. This also introduces a new virtual device, spapr-tpm-proxy, which is used to configure the host TPM path to be used to service requests sent by H_TPM_COMM hcalls, for example: -device spapr-tpm-proxy,id=tpmp0,host-path=/dev/tpmrm0 By default, no spapr-tpm-proxy will be created, and hcalls will return H_FUNCTION. The full specification for this hypercall can be found in docs/specs/ppc-spapr-uv-hcalls.txt Since SVM-related hcalls like H_TPM_COMM use a reserved range of 0xEF00-0xEF80, we introduce a separate hcall table here to handle them.

Re-read the timebase before migrate was ported from x86 commit: 6053a86fe7bd: kvmclock: reduce kvmclock difference on migration The clock move makes the guest knows about the paused time between the stop and migrate commands. This is an issue in an already-paused VM because some side effects, like process stalls, could happen after migration.

2019-08-21audio: add audiodev properties to frontendsKővágó, Zoltán13-1/+84
Finally add audiodev= options to audio frontends so users can specify which backend to use when multiple backends exist. Not specifying an audiodev= option currently causes the first audiodev to be used, this is fixed in the next commit.

2019-08-20scsi: lsi: exit infinite loop while executing script (CVE-2019-12068)Paolo Bonzini1-14/+27
When executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's->dsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well.

2019-08-20migration: do not rom_reset() during incoming migrationCatherine Ho1-0/+10
Commit 18269069c310 ("migration: Introduce ignore-shared capability") addes ignore-shared capability to bypass the shared ramblock (e,g, membackend + numa node). It does good to live migration. As told by Yury,this commit expectes that QEMU doesn't write to guest RAM until VM starts, but it does on aarch64 qemu: Backtrace: 1 0x000055f4a296dd84 in address_space_write_rom_internal () at exec.c:3458 2 0x000055f4a296de3a in address_space_write_rom () at exec.c:3479 3 0x000055f4a2d519ff in rom_reset () at hw/core/loader.c:1101 4 0x000055f4a2d475ec in qemu_devices_reset () at hw/core/reset.c:69 5 0x000055f4a2c90a28 in qemu_system_reset () at vl.c:1675 6 0x000055f4a2c9851d in main () at vl.c:4552 Actually, on arm64 virt marchine, ramblock "dtb" will be filled into ram druing rom_reset. In ignore-shared incoming case, this rom filling is not required since all the data has been stored in memory backend file. Further more, as suggested by Peter Xu, if we do rom_reset() now with these ROMs then the RAM data should be re-filled again too with the migration stream coming in.
