2013-10-10xen_disk: mark ioreq as mapped before unmapping in error caseMatthew Daley
Commit 4472beae modified the semantics of ioreq_{un,}map so that they are idempotent if called when they're not needed (ie., twice in a row). However, it neglected to handle the case where batch mapping is not being used (the default), and one of the grants fails to map. In this case, ioreq_unmap will be called to unwind and unmap any mappings already performed, but ioreq_unmap simply returns due to the aforementioned change (the ioreq has not already been marked as mapped). The frontend user can therefore force xen_disk to leak grant mappings, a per-domain limited resource. Fix by marking the ioreq as mapped before calling ioreq_unmap in this situation.

2013-10-05hw/9pfs: Fix errno value for xattr functionsDaniel P. Berrange
If there is no operation driver for the xattr type the functions return '-1' and set errno to '-EOPNOTSUPP'. When the calling code sets 'ret = -errno' this turns into a large positive number. In Linux 3.11, the kernel has switched to using 9p version 9p2000.L, instead of 9p2000.u, which enables support for xattr operations. This on its own is harmless, but for another change which makes it request the xattr with a name 'security.capability'. The result is that the guest sees a succesful return of 95 bytes of data, instead of a failure with errno set to 95. Since the kernel expects a maximum of 20 bytes for an xattr return this gets translated to the unexpected errno ERANGE. This all means that when running a binary off a 9p fs in 3.11 kernels you get a fun result of: # ./date sh: ./date: Numerical result out of range The only workaround is to pass 'version=9p2000.u' when mounting the 9p fs in the guest, to disable all use of xattrs.

2013-10-02vfio-pci: Implement PCI hot resetAlex Williamson
Now that VFIO has a PCI hot reset interface, take advantage of it. There are two modes that we need to consider. The first is when only one device within the set of devices affected is actually assigned to the guest. In this case the other devices are are just held by VFIO for isolation and we can pretend they're not there, doing an entire bus reset whenever the device reset callback is triggered. Supporting this case separately allows us to do the best reset we can do of the device even if the device is hotplugged. The second mode is when multiple affected devices are all exposed to the guest. In this case we can only do a hot reset when the entire system is being reset. However, this also allows us to track which individual devices are affected by a reset and only do them once. We split our reset function into pre- and post-reset helper functions prioritize the types of device resets available to us, and create separate _one vs _multi reset interfaces to handle the distinct cases above.

2013-10-02vfio-pci: Lazy PCI option ROM loadingAlex Williamson
During vfio-pci initfn, the device is not always in a state where the option ROM can be read. In the case of graphics cards, there's often no per function reset, which means we have host driver state affecting whether the option ROM is usable. Ideally we want to move reading the option ROM past any co-assigned device resets to the point where the guest first tries to read the ROM itself. To accomplish this, we switch the memory region for the option rom to an I/O region rather than a memory mapped region. This has the side benefit that we don't waste KVM memory slots for a BAR where we don't care about performance. This also allows us to delay loading the ROM from the device until the first read by the guest. We then use the PCI config space size of the ROM BAR when setting up the BAR through QEMU PCI. Another benefit of this approach is that previously when a user set the ROM to a file using the romfile= option, we still probed VFIO for the parameters of the ROM, which can result in dmesg errors about an invalid ROM. We now only probe VFIO to get the ROM contents if the guest actually tries to read the ROM. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2013-10-02vfio-pci: Test device reset capabilitiesAlex Williamson
Not all resets are created equal. PM reset is not very reliable, especially for GPUs, so we might want to opt for a bus reset if a standard reset will only do a D3hot->D0 transition. We can also use this to tell if the standard reset will do a bus reset (if neither has_pm_reset or has_flr is probed, but the device still supports reset). Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2013-10-02vfio-pci: Add support for MSI affinityAlex Williamson
When MSI is accelerated through KVM the vectors are only programmed when the guest first enables MSI support.  Subsequent writes to the vector address or data fields are ignored.  Unfortunately that means we're ignore updates done to adjust SMP affinity of the vectors. MSI SMP affinity already works in non-KVM mode because the address and data fields are read from their backing store on each interrupt. This patch stores the MSIMessage programmed into KVM so that we can determine when changes are made and update the routes. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

This is a bunch of fixes/changes for the s390 architecture. It also contains the fixes from the previous pull request, which did not make it yet. Overall it contains - a fix for kexec without kdump (which uses diag308 subcode 0 instead of 1) - several sclp related fixes - some initial sclp migration code - the sclp line mode console - A fix for a boot problem with the virtio ccw ipl bios - zeroed out padding bytes for the notes section of dump-guest-memory - some cleanups # gpg: Signature made Tue 24 Sep 2013 02:18:44 AM CDT using RSA key ID B5A61C7C # gpg: Can't check signature: public key not found # By Christian Borntraeger (6) and others # Via Christian Borntraeger * borntraeger/tags/s390-next-20130924: s390/sclplmconsole: Add support for SCLP line-mode console s390/ebcdic: Move conversion tables to header file s390/eventfacility: allow childs to handle more than 1 event type s390/eventfacility: remove unused event_type variable s390/eventfacility: Fix receive/send masks s390/eventfacility: fix multiple Read Event Data sources s390/sclp: add reset() functions s390/sclpquiesce: Add code to support live migration s390/sclpconsole: Add code to support live migration for sclpconsole s390/sclpconsole: modify definition of input buffer s390/kexec: Implement diag308 subcode 0 s390/ioinst: Moved the CC setting to the IO instruction handlers s390/cpu: Make setcc() function available to other files s390/ipl: Update the s390-ccw.img rom s390/ipl: Fix waiting for virtio processing s390/dump: zero out padding bytes in notes sections s390/kvm: Add check for priviledged SCLP handler Message-id: 1380007671-18976-1-git-send-email-borntraeger@de.ibm.com
