Unbinding a PCI device from the stub driver can require several steps, and it can be useful for debugging to be able to trace which of these steps are performed and which are skipped for each device.

The name is confusing, and there are just two uses: one is a test case, and the other will be removed as part of an upcoming refactoring of the hostdev code.

Most of the changes to the list of active and inactive PCI devices happen in virHostdev, where they are properly logged. virPCIDeviceDetach() and virPCIDeviceReattach(), however, change the inactive list as well, so they should be logging similar messages.

This overkill has no place in production code, so this patch removes it.

This replaces the virPCIKnownStubs string array that was used internally for stub driver validation. Advantages: * possible values are well-defined * typos in driver names will be detected at compile time * avoids having several copies of the same string around * no error checking required when setting / getting value The names used mirror those in the virDomainHostdevSubsysPCIBackendType enumeration.
-
由 Andrea Bolognani 提交于
The value is not inspected inside the function, so it makes more sense for the caller to change the device's setting explicitly.

This internal function supports, in theory, binding to a different stub driver than the one the PCI device has been configured to use. In practice, it is only ever called like virPCIDeviceBindToStub(dev, dev->stubDriver); which makes its second parameter redundant. Get rid of it, along with the extra string copy required to support it.

Instead of replicating the information (domain, bus, slot, function) inside the virPCIDevice structure, use the already-existing virPCIDeviceAddress structure. For users of the module, this means that the object returned by virPCIDeviceGetAddress() can no longer be NULL and must no longer be freed by the caller.

A PCI device may have the capability to setup virtual functions (VFs) but have them currently all disabled. Prior to this patch, if that was the case the the node device XML for the device wouldn't report any virtual_functions capability. With this patch, if a file called "sriov_totalvfs" is found in the device's sysfs directory, its contents will be interpreted as a decimal number, and that value will be reported as "maxCount" in a capability element of the device's XML, e.g.: <capability type='virtual_functions' maxCount='7'/> This will be reported regardless of whether or not any VFs are currently enabled for the device. NB: sriov_numvfs (the number of VFs currently active) is also available in sysfs, but that value is implied by the number of items in the list that is inside the capability element, so there is no reason to explicitly provide it as an attribute. sriov_totalvfs and sriov_numvfs are available in kernels at least as far back as the 2.6.32 that is in RHEL6.7, but in the case that they simply aren't there, libvirt will behave as it did prior to this patch - no maxCount will be displayed, and the virtual_functions capability will be absent from the device's XML when 0 VFs are enabled.

In making the conversion to the new API, I fixed a couple bugs: virSCSIDeviceGetSgName would leak memory if a directory unexpectedly contained multiple entries; virNetDevTapGetRealDeviceName could report a spurious error from a stale errno inherited before starting the readdir search. The decision on whether to store the result of virDirRead into a variable is based on whether the end of the loop falls through to cleanup code automatically. In some cases, we have loops that are documented to return NULL on failure, and which raise an error on most failure paths but not in the case where the directory was unexpectedly empty; it may be worth a followup patch to explicitly report an error if readdir was successful but the directory was empty, so that a NULL return always has an error set. * src/util/vircgroup.c (virCgroupRemoveRecursively): Use new interface.

Coverity complains about "USE_AFTER_FREE" due to how virPCIDeviceSetStubDriver "could" return either -1, 0, or 1 from the VIR_STRDUP() and then possibly makes a call to virPCIDeviceDetach(). The only way this could happen is if NULL were passed as the "driver" name and virStrdup() returned 0. Since the calling functions check < 0 on the initial function call, the 0 possibility causes Coverity to complain. To fix this - enforce that the second parameter is not NULL using ATTRIBUTE_NONNULL(2) for the function prototype, then in virPCIDeviceDetach add an sa_assert(dev->stubDriver). This will result in Coverity not complaining any more.

For example, even though a device seemed to be detached virsh # nodedev-detach pci_0000_07_05_0 --driver vfio Device pci_0000_07_05_0 detached one could find similar message in libvirt logs: Failed to bind PCI device '0000:07:05.0' to vfio-pci: No such device This patch fixes these paths and also avoids overwriting real errors with errors encountered during a cleanup phase.

Like commit 94a26c7e from Eric Blake, the old fuzzy code should be replaced by the new array management macros now. And the type of scsi->count should be changed into "size_t", and thus virSCSIDeviceListCount should return size_t instead, similar for vir{PCI,USB}DeviceListCount.

When determining if a device is behind a PCI bridge, the PCI device class is checked by reading the config space. However, there are some devices which have the wrong class on the config space, but the class is initialized by Linux correctly as a PCI BRIDGE. This class can be read by the sysfs file '/sys/bus/pci/devices/xxxx:xx:xx.x/class'. One example of such bridge is IBM PCI Bridge 1014:03b9, which is identified as a Host Bridge when reading the config space. Signed-off-by: NThadeu Lima de Souza Cascardo <cascardo@linux.vnet.ibm.com>

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1025397 When virPCIGetVirtualFunctions created the list of an SRIOV Physical Function's (PF) Virtual Functions (VF), it had assumed that the order of "virtfn*" links returned by readdir() from the PF's sysfs directory was already in the correct order. Experience has shown that this is not always the case - it can be in alphabetical order (which would e.g. place virtfn11 before virtfn2) or even some seemingly random order (see the example in the bugzilla report) This results in 1) incorrect assumptions made by consumers of the output of the virt_functions list of virsh nodedev-dumpxml, and 2) setting MAC address and vlan tag on the wrong VF (since libvirt uses netlink to set mac address and vlan tag, netlink requires the VF#, and the function virPCIGetVirtualFunctionIndex() returns the wrong index due to the improperly ordered VF list). The solution provided by this patch is for virPCIGetVirtualFunctions to no longer scan the entire device directory in its natural order, but instead to check for links individually by name "virtfn%d" where %d starts at 0 and increases with each success. Since VFs are created contiguously by the kernel, this will guarantee that all VFs are found, and placed in the arry in the correct order. One note of use to the uninitiated is that VIR_APPEND_ELEMENT always either increments *num_virtual_functions or fails, so no this isn't an endless loop. (NB: the SRIOV_* defines at the top of virpci.c were removed because they are unnecessary and/or not used.)
