2016-09-19crypto: clear out buffer after timing pbkdf algorithmDaniel P. Berrange1-4/+9
The 'out' buffer will hold a key derived from master password, so it is best practice to clear this buffer when no longer required. At this time, the code isn't worrying about locking buffers into RAM to prevent swapping sensitive data to disk. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2016-09-19crypto: make PBKDF iterations configurable for LUKS formatDaniel P. Berrange3-1/+35
As protection against bruteforcing passphrases, the PBKDF algorithm is tuned by counting the number of iterations needed to produce 1 second of running time. If the machine that the image will be used on is much faster than the machine where the image is created, it can be desirable to raise the number of iterations. This change adds a new 'iter-time' property that allows the user to choose the iteration wallclock time. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2016-09-19crypto: use uint64_t for pbkdf iteration count parametersDaniel P. Berrange6-40/+57
The qcrypto_pbkdf_count_iters method uses a 64 bit int but then checks its value against INT32_MAX before returning it. This bounds check is premature, because the calling code may well scale the iteration count by some value. It is thus better to return a 64-bit integer and let the caller do range checking. For consistency the qcrypto_pbkdf method is also changed to accept a 64bit int, though this is somewhat academic since nettle is limited to taking an 'int' while gcrypt is limited to taking a 'long int'.

2016-09-16tcg: Merge GETPC and GETRARichard Henderson7-50/+30
The return address argument to the softmmu template helpers was confused. In the legacy case, we wanted to indicate that there is no return address, and so passed in NULL. However, we then immediately subtracted GETPC_ADJ from NULL, resulting in a non-zero value, indicating the presence of an (invalid) return address. Push the GETPC_ADJ subtraction down to the only point it's required: immediately before use within cpu_restore_state_from_tb, after all NULL pointer checks have been completed. This makes GETPC and GETRA identical. Remove GETRA as the lesser used macro, replacing all uses with GETPC. Signed-off-by: Richard Henderson <rth@twiddle.net>

2016-09-15vfio/pci: Fix regression in MSI routing configurationDavid Gibson1-1/+3
d1f6af6 "kvm-irqchip: simplify kvm_irqchip_add_msi_route" was a cleanup of kvmchip routing configuration, that was mostly intended for x86. However, it also contains a subtle change in behaviour which breaks EEH[1] error recovery on certain VFIO passthrough devices on spapr guests. So far it's only been seen on a BCM5719 NIC on a POWER8 server, but there may be other hardware with the same problem. It's also possible there could be circumstances where it causes a bug on x86 as well, though I don't know of any obvious candidates. Prior to d1f6af6, both vfio_msix_vector_do_use() and vfio_add_kvm_msi_virq() used msg == NULL as a special flag to mark this as the "dummy" vector used to make the host hardware state sync with the guest expected hardware state in terms of MSI configuration. Specifically that flag caused vfio_add_kvm_msi_virq() to become a no-op, meaning the dummy irq would always be delivered via qemu. d1f6af6 changed vfio_add_kvm_msi_virq() so it takes a vector number instead of the msg parameter, and determines the correct message itself. The test for !msg was removed, and not replaced with anything there or in the caller. With an spapr guest which has a VFIO device, if an EEH error occurs on the host hardware, then the device will be isolated then reset. This is a combination of host and guest action, mediated by some EEH related hypercalls. I haven't fully traced the mechanics, but somehow installing the kvm irqchip route for the dummy irq on the BCM5719 means that after EEH reset and recovery, at least some irqs are no longer delivered to the guest. In particular, the guest never gets the link up event, and so the NIC is effectively dead. [1] EEH (Enhanced Error Handling) is an IBM POWER server specific PCI-* error reporting and recovery mechanism. The concept is somewhat similar to PCI-E AER, but the details are different.

2016-09-15virtio-bus: Plug devices after features are negotiatedMaxime Coquelin5-28/+62
Currently, devices are plugged before features are negotiated. If the backend doesn't support VIRTIO_F_VERSION_1, the transport needs to rewind some settings. This is the case for CCW, for which a post_plugged callback had been introduced, where max_rev field is just updated if VIRTIO_F_VERSION_1 is not supported by the backend. For PCI, implementing post_plugged would be much more complicated, so it needs to know whether the backend supports VIRTIO_F_VERSION_1 at plug time. Currently, nothing is done for PCI. Modern capabilities get exposed to the guest even if VIRTIO_F_VERSION_1 is not supported by the backend, which confuses the guest. This patch replaces existing post_plugged solution with an approach that fits with both transports. Features negotiation is performed before ->device_plugged() call. A pre_plugged callback is introduced so that the transports can set their supported features. Cc: Michael S.

2016-09-15curl: Operate on zero-length fileTomáš Golembiovský1-4/+21
Another attempt to fix the bug 1596870. When creating new disk backed by remote file accessed via HTTPS and the backing file has zero length, qemu-img terminates with uniformative error message: qemu-img: disk.qcow2: CURL: Error opening file: While it may not make much sense to operate on empty file, other block backends (e.g. raw backend for regular files) seem to allow it. This patch fixes it for the curl backend and improves the reported error. Signed-off-by: Tomáš Golembiovský <tgolembi@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
