2014-10-31kvm_stat: Abstract ioctl numbersMichael Ellerman
Unfortunately ioctl numbers are platform specific, so abstract them out of the code so they can be overridden. As it happens x86 and s390 share the same values, so nothing needs to change yet. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31kvm_stat: Rework platform detectionMichael Ellerman
The current platform detection is a little bit messy. We look for lines in /proc/cpuinfo starting with 'flags' OR 'vendor-id', and scan both for values we know will only occur in one or the other. We also keep scanning once we've found a value, which could be a feature, but isn't in this case. We'd also like to add another platform, powerpc, which will just make it worse. So clean it up in preparation. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31kvm_stat: Fix the non-x86 exit reasonsMichael Ellerman
In kvm_stat we have a dictionary of exit reasons for s390. Firstly these are not s390 specific, they are the generic exit reasons. So rename the dictionary to reflect that, and add it separately to filters[]. Secondly, the values are defined using hex, but in the kernel header they are decimal. That means values above 9 in kvm_stat are incorrect. While we're there, fix the whitespace to match the rest of the file.

2014-10-31kvm_stat: Only consider online cpusMichael Ellerman
In kvm_stat we grovel through /sys to find out how many cpus are in the system. However if a cpu is offline it will still be present in /sys, and the perf_event_open() will fail. Modify the logic to only return online cpus. We need to be careful on systems which don't support cpu hotplug, the online file will not be present at all.

2014-10-31iscsi: Refuse to open as writable if the LUN is write protectedFam Zheng
Before, when a write protected iSCSI target is attached as scsi-disk with BDRV_O_RDWR, we report it as writable, while in fact all writes will fail. One way to improve this is to report write protect flag as true to guest, but a even better way is to refuse using a write protected LUN to guest. Target write protect flag is checked with a mode sense query. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31kvmvapic: patch_instruction fixPavel Dovgalyuk
When QEMU works in icount mode cpu_restore_state function performs two actions: restoring the program counter and updating icount to the correct value. kvmvapic's patch_instruction function is called by cpu_report_tpr_access function which also invokes cpu_restore_state. It results to calling cpu_restore_state twice - in cpu_report_tpr_access and in patch_instruction. When icount is disabled second call is safe. But when icount is enabled, cpu_restore_state modifies instructions counter twice, which leads to incorrect behavior. This patch removes useless cpu_restore_state call from kvmvapic.

2014-10-31vl.c: Fix Coverity complaining for vmstate_dump_fileGonglei
commit abfd9ce3(migration: dump vmstate info as a json file for static analysis) introduce a new command, '-dump-vmstate', that takes a filename as an argument. When executed, QEMU will dump the vmstate information for the machine type it's invoked with to the file, and quit. However, only one instance of the -dump-vmstate option is supported. If more were given, the vmstate_dump_file variable would be overwritten. This fix also helps silence a Coverity error.

2014-10-31megasas: Fixup MSI-X handlingHannes Reinecke
MSI-X works slightly different than INTx; the doorbell registers are not necessarily used as MSI-X interrupts are directed anyway.

2014-10-28libcacard: Lock NSS cert db when selecting an applet on an emulated cardRay Strode
When a process in a guest uses an emulated smartcard, libcacard running on the host passes the PIN from the guest to the PK11_Authenticate NSS function. The first time PK11_Authenticate is called the passed in PIN is used to unlock the certificate database. Subsequent calls to PK11_Authenticate will transparently succeed, regardless of the passed in PIN. This is a convenience for applications provided by NSS. Of course, the guest may have many applications using the one emulated smart card all driven from the same host QEMU process. That means if a user enters the right PIN in one program in the guest, and then enters the wrong PIN in another program in the guest, the wrong PIN will still successfully unlock the virtual smartcard. This commit forces the NSS certificate database to be locked anytime an applet is selected on an emulated smartcard by calling vcard_emul_logout.
