[libvirt] [PATCH] Revert "hostdev: Use actual device when reattaching"

This reverts commit ee4cfb56436b50345b072c706b87aff82e06d760. Since we're still not persisting our bookkeeping lists across daemon restarts, we might have lost some information virPCIDeviceReattach() relies on, for example whether the device needs to be unbound from the stub driver. As a result, if the daemon has been restarted in the meantime, the device might end up remaining bound to the stub driver even after 'virsh nodedev-reattach' or similar has been called, with no way of giving it back to the host short of messing with sysfs behind libvirt's back. Revert back to the previous behavior of always trying to bind the device to the host driver, regardless of its status when it was detached, until persistent bookkeeping lists have been implemented. --- src/util/virhostdev.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/src/util/virhostdev.c b/src/util/virhostdev.c index b397b79..933c942 100644 --- a/src/util/virhostdev.c +++ b/src/util/virhostdev.c @@ -1658,7 +1658,6 @@ virHostdevPCINodeDeviceReAttach(virHostdevManagerPtr mgr, virPCIDevicePtr pci) { struct virHostdevIsPCINodeDeviceUsedData data = { mgr, NULL, false }; - virPCIDevicePtr actual; int ret = -1; virObjectLock(mgr->activePCIHostdevs); @@ -1667,12 +1666,11 @@ virHostdevPCINodeDeviceReAttach(virHostdevManagerPtr mgr, if (virHostdevIsPCINodeDeviceUsed(virPCIDeviceGetAddress(pci), &data)) goto cleanup; - /* We need to look up the actual device because that's what - * virPCIDeviceReattach() expects as its argument */ - if (!(actual = virPCIDeviceListFind(mgr->inactivePCIHostdevs, pci))) - goto cleanup; + virPCIDeviceSetUnbindFromStub(pci, true); + virPCIDeviceSetRemoveSlot(pci, true); + virPCIDeviceSetReprobe(pci, true); - if (virPCIDeviceReattach(actual, mgr->activePCIHostdevs, + if (virPCIDeviceReattach(pci, mgr->activePCIHostdevs, mgr->inactivePCIHostdevs) < 0) goto cleanup; -- 2.5.5
