From c2150285aff9b308b969d5fc6f32f75db620dfe3 Mon Sep 17 00:00:00 2001 Message-ID: From: Jonathon Jongsma Date: Tue, 18 Jul 2023 14:47:49 -0500 Subject: [PATCH] nodedev: report mdev persistence properly Since commit 44a0f2f0, we now query mdevctl for transient (active) mdevs in order to gather attributes for the mdev. Unfortunately, this commit introduced a regression because nodeDeviceUpdateMediatedDevice() assumed that all mdevs returned from mdevctl were actually persistent mdevs but we were using it to update transient mdevs. Refactor the function so that we can use it to update both persistent and transient mdevs. Signed-off-by: Jonathon Jongsma Reviewed-by: Michal Privoznik Reviewed-by: Boris Fiuczynski Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2143158 (cherry picked from commit fa0d5f4ebc0aa178d9dea278914f9149a4c4af54) Signed-off-by: Jonathon Jongsma --- src/node_device/node_device_driver.c | 21 +++++++++++---------- 1 file changed, 11 insertions(+), 10 deletions(-) diff --git a/src/node_device/node_device_driver.c b/src/node_device/node_device_driver.c index a2d0600560..5dc45ddbb4 100644 --- a/src/node_device/node_device_driver.c +++ b/src/node_device/node_device_driver.c @@ -1339,11 +1339,12 @@ nodeDeviceDestroy(virNodeDevicePtr device) /* takes ownership of @def and potentially frees it. @def should not be used * after returning from this function */ static int -nodeDeviceUpdateMediatedDevice(virNodeDeviceDef *def) +nodeDeviceUpdateMediatedDevice(virNodeDeviceDef *def, + bool defined) { virNodeDeviceObj *obj; virObjectEvent *event; - bool defined = false; + bool was_defined = false; g_autoptr(virNodeDeviceDef) owned = def; g_autofree char *name = g_strdup(owned->name); @@ -1359,13 +1360,13 @@ nodeDeviceUpdateMediatedDevice(virNodeDeviceDef *def) bool changed; virNodeDeviceDef *olddef = virNodeDeviceObjGetDef(obj); - defined = virNodeDeviceObjIsPersistent(obj); + was_defined = virNodeDeviceObjIsPersistent(obj); /* Active devices contain some additional information (e.g. sysfs * path) that is not provided by mdevctl, so re-use the existing * definition and copy over new mdev data */ changed = nodeDeviceDefCopyFromMdevctl(olddef, owned); - if (defined && !changed) { + if (was_defined && !changed) { /* if this device was already defined and the definition * hasn't changed, there's nothing to do for this device */ virNodeDeviceObjEndAPI(&obj); @@ -1373,11 +1374,11 @@ nodeDeviceUpdateMediatedDevice(virNodeDeviceDef *def) } } - /* all devices returned by virMdevctlListDefined() are persistent */ - virNodeDeviceObjSetPersistent(obj, true); + if (defined) + virNodeDeviceObjSetPersistent(obj, true); virNodeDeviceObjSetAutostart(obj, def->caps->data.mdev.autostart); - if (!defined) + if (!was_defined && defined) event = virNodeDeviceEventLifecycleNew(name, VIR_NODE_DEVICE_EVENT_DEFINED, 0); @@ -1447,7 +1448,7 @@ nodeDeviceDefineXML(virConnect *conn, * have already received the uuid from virMdevctlDefine(), we can simply * add the provisional device to the list and return it immediately and * avoid this long delay. */ - if (nodeDeviceUpdateMediatedDevice(g_steal_pointer(&def)) < 0) + if (nodeDeviceUpdateMediatedDevice(g_steal_pointer(&def), true) < 0) return NULL; return virGetNodeDevice(conn, name); @@ -1742,7 +1743,7 @@ nodeDeviceUpdateMediatedDevices(void) removeMissingPersistentMdev, &data); for (i = 0; i < data.ndefs; i++) - if (nodeDeviceUpdateMediatedDevice(defs[i]) < 0) + if (nodeDeviceUpdateMediatedDevice(defs[i], true) < 0) return -1; /* Update active/transient mdev devices */ @@ -1753,7 +1754,7 @@ nodeDeviceUpdateMediatedDevices(void) } for (i = 0; i < act_ndefs; i++) - if (nodeDeviceUpdateMediatedDevice(act_defs[i]) < 0) + if (nodeDeviceUpdateMediatedDevice(act_defs[i], false) < 0) return -1; return 0; -- 2.41.0
