2016-11-14blockjob: fix dead pointer in txn listVladimir Sementsov-Ogievskiy
Though it is not intended to be reached through normal circumstances, if we do not gracefully deconstruct the transaction QLIST, we may wind up with stale pointers in the list. The rest of this series attempts to address the underlying issues, but this should fix list inconsistencies.

2016-11-15boot-serial-test: Add a test for the powernv machineThomas Huth
The new powernv machine ships with a firmware that outputs some text to the serial console, so we can automatically test this machine type in the boot-serial tester, too. And to get some (very limited) test coverage for the new POWER9 CPU emulation, too, this test is also started with "-cpu POWER9".

2016-11-15ppc/pnv: Fix fatal bug on 32-bit hostsDavid Gibson
If the pnv machine type is compiled on a 32-bit host, the unsigned long (host) type is 32-bit. This means that the hweight_long() used to calculate the number of allowed cores only considers the low 32 bits of the cores_mask variable, and can thus return 0 in some circumstances. This corrects the bug.

2016-11-15spapr-vty: Fix bad assert() statementThomas Huth
When using the serial console in the GTK interface of QEMU (and QEMU has been compiled with CONFIG_VTE), it is possible to trigger the assert() statement in vty_receive() in spapr_vty.c by pasting a chunk of text with length > 16 into the QEMU window. Most of the other serial backends seem to simply drop characters that they can not handle, so I think we should also do the same in spapr-vty to fix this issue.

2016-11-15FU exceptions should carry a cause (IC)Balbir Singh
As per the ISA we need a cause and executing a tabort r9 in libc for example causes a EXCP_FU exception, we don't wire up the IC (cause) when we post the exception. The cause is required for the kernel to do the right thing. The fix applies only to 64 bit ppc targets.

2016-11-15spapr: Fix migration of PCI host bridges from qemu-2.7David Gibson
daa2369 "spapr_pci: Add a 64-bit MMIO window" subtly broke migration from qemu-2.7 to the current version. It split the device's MMIO window into two pieces for 32-bit and 64-bit MMIO. The patch included backwards compatibility code to convert the old property into the new format. However, the property value was also transferred in the migration stream and compared with a (probably unwise) VMSTATE_EQUAL. So, the "raw" value from 2.7 is compared to the new style converted value from (pre-)2.8 giving a mismatch and migration failure. Although it would be technically possible to fix this in a way allowing backwards migration, that would leave an ugly legacy around indefinitely. This patch takes the simpler approach of bumping the migration version, dropping the unwise VMSTATE_EQUAL (and some equally unwise ones around it) and ignoring them on an incoming migration.

2016-11-15ppc: Remove some stub POWER6 modelsDavid Gibson
The CPU model table includes stub (commented out) definitions for CPU_POWERPC_POWER6_5 and CPU_POWERPC_POWER6A. These are not real cpu models, but represent the POWER6 in some compatiblity modes. If we ever do implement POWER6 (unlikely), we'll implement its compatibility modes in a different way (similar to what we do for POWER7 and POWER8). So these stub definitions can be removed.

2016-11-15powernv: CPU compatibility modes don't make sense for powernvDavid Gibson
powernv has some code (derived from the spapr equivalent) used in device tree generation which depends on the CPU's compatibility mode / logical PVR. However, compatibility modes don't make sense on powernv - at least not as a property controlled by the host - because the guest in powernv has full hypervisor level access to the virtual system, and so owns the PCR (Processor Compatibility Register) which implements compatiblity modes. Note: the new logic doesn't take into account kvmppc_smt_threads() like the old version did. However, if core->nr_threads exceeds kvmppc_smt_threads() then things will already be broken and clamping the value in the device tree isn't going to save us.

2016-11-14migration: Fix return code of ram_save_iterate()Thomas Huth
qemu_savevm_state_iterate() expects the iterators to return 1 when they are done, and 0 if there is still something left to do. However, ram_save_iterate() does not obey this rule and returns the number of saved pages instead. This causes a fatal hang with ppc64 guests when you run QEMU like this (also works with TCG): qemu-img create -f qcow2 /tmp/test.qcow2 1M qemu-system-ppc64 -nographic -nodefaults -m 256 \ -hda /tmp/test.qcow2 -serial mon:stdio ... then switch to the monitor by pressing CTRL-a c and try to save a snapshot with "savevm test1" for example. After the first iteration, ram_save_iterate() always returns 0 here, so that qemu_savevm_state_iterate() hangs in an endless loop and you can only "kill -9" the QEMU process. Fix it by using proper return values in ram_save_iterate().

2016-11-14block-backend: Always notify on blk_ejectJohn Snow
blk_eject is only used by scsi-disk and atapi, and in both cases we only attempt to invoke blk_eject if we have a bona-fide change in tray state. The "issue" here is that the tray state does not generate a QMP event unless there is a medium/BDS attached to the device, so if libvirt et al are waiting for a tray event to occur from an empty-but-closed drive, software opening that drive will not emit an event and libvirt will wait forever. Change this by modifying blk_eject to always emit an event, instead of conditionally on a "real" backend eject.

2016-11-14ahci-test: test atapi read_cd with bcl, nb_sectors = 0John Snow
Commit 9ef2e93f introduced the concept of tagging ATAPI commands as NONDATA, but this introduced a regression for certain commands better described as CONDDATA. read_cd is such a command that both requires a non-zero BCL if a transfer size is set, but is perfectly content to accept a zero BCL if the transfer size is 0. This test adds a regression test for the case where BCL and nb_sectors are both 0. Flesh out the CDROM tests by: (1) Allowing the test to specify a BCL (2) Allowing the buffer comparison test to compare a 0-size buffer (3) Fix the BCL specification in libqos (It is LE, not BE) (4) Add a nice human-readable message for future SCSI command additions Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Kevin Wolf <kwolf@redhat.com> Message-id: 1477970211-25754-4-git-send-email-jsnow@redhat.com [Line length edit --js] Signed-off-by: John Snow <jsnow@redhat.com>

We make sure that the size is aligned to sector length to prevent any round ups. Otherwise we could end up reading/writing data outside the area specified by user. This is only needed when user supplies the size option to avoid any surprises. It is not necessary when only offset is set. More over, the check made it difficult to use the offset option without size option. The check puts unneeded restriction on the offset which had to be aligned too. Because bdrv_getlength() returns aligned value having unaligned offset would make the check fail. Signed-off-by: Tomáš Golembiovský <tgolembi@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2016-11-11raw_bsd: move check to prevent overflowTomáš Golembiovský
When only offset is specified but no size and the offset is greater than the real size of the containing device an overflow occurs when parsing the options. This overflow is harmless because we do check for this exact situation little bit later, but it leads to an error message with weird values. It is better to do the check is sooner and prevent the overflow. Signed-off-by: Tomáš Golembiovský <tgolembi@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2016-11-11hmp: Make block_stream set an explicit job IDAlberto Garcia
A job ID is always required in order to create a block job on a non-root node. The default ID (obtained with bdrv_get_device_name()) is otherwise empty in this scenario and the job cannot be created. The HMP block_stream command doesn't set a job ID and therefore it doesn't allow streaming to intermediate nodes. One solution is to add an extra parameter to set a job ID. The other solution is to simply use the node name passed to block_stream as job ID. This won't work if it's automatically generated (because it contains a '#') but is otherwise simple enough for all other cases. This way 'block_stream node3' will create a job with the ID 'node3' and the good old 'block_stream virtio0' will keep the previous behaviour and use 'virtio0' for the job ID.
