[PATCH v7 00/11] Configurable policy for handling deprecated interfaces
by Markus Armbruster 18 Mar '21

18 Mar '21

New option -compat lets you configure what to do when deprecated interfaces get used. This is intended for testing users of the management interfaces. It is experimental. -compat deprecated-input=<in-policy> configures what to do when deprecated input is received. Available policies: * accept: Accept deprecated commands and arguments (default) * reject: Reject them * crash: Crash -compat deprecated-output=<out-policy> configures what to do when deprecated output is sent. Available output policies: * accept: Emit deprecated command results and events (default) * hide: Suppress them For now, -compat covers only deprecated syntactic aspects of QMP.

[libvirt PATCH 00/38] Refactor XML parsing boilerplate code
by Tim Wiederhake 18 Mar '21

18 Mar '21

This series replaces some recurring boilerplate code in src/conf/ regarding the extraction of a virTristate(Switch|Bool) XML attribute. The boilerplate code looks roughly like this, g_autofree char *str = NULL; if (str = virXMLPropString(node, ...)) { int val; if ((val = virTristateBoolTypeFromString(str)) <= 0) { virReportError(...) return -1; } def->... = val; } with some variations regarding how `str` is free'd in case of later re-use, the exact error message for invalid values, whether or not `VIR_TRISTATE_(SWITCH|BOOL)_ABSENT` is explicitly checked for (`val < 0` vs. `val <= 0`), whether an intermediate variable is used or the value is assigned directly, and in some cases the conditions in the two if-blocks are merged. As a side effect, this makes the error messages for invalid values in these attributes much more consistent and catches some instances where e.g. `<foo bar="default"/>` would incorrectly be accepted. Patch #11 (virDomainChrSourceReconnectDefParseXML) is a good example of what this refactoring is about. Tim Wiederhake (38): virStorageAdapterFCHost: Fix comment virxml: Add virXMLPropYesNo virxml: Add virXMLPropOnOff domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainKeyWrapCipherDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainVirtioOptionsParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainDeviceInfoParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainDiskSourceNetworkParse domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainDiskSourceNVMeParse domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainDiskDefDriverParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainActualNetDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainChrSourceReconnectDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainNetDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainChrSourceDefParseTCP domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainChrSourceDefParseFile domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainChrSourceDefParseLog domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainGraphicsDefParseXMLVNC domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainGraphicsDefParseXMLSDL domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainGraphicsDefParseXMLSpice domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainAudioCommonParse domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainAudioJackParse domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainAudioOSSParse domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainAudioDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainMemballoonDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainShmemDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainPerfEventDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainMemoryDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainIOMMUDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainVsockDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainFeaturesDefParse domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainLoaderDefParseXML domain_conf: Use virXMLProp(OnOff|YesNo) in virDomainVcpuParse backup_conf: Use virXMLProp(OnOff|YesNo) in virDomainBackupDiskDefParseXML backup_conf: Use virXMLProp(OnOff|YesNo) in virDomainBackupDefParse device_conf: Use virXMLProp(OnOff|YesNo) in virPCIDeviceAddressParseXML network_conf: Use virXMLProp(OnOff|YesNo) in virNetworkForwardNatDefParseXML numa_conf: Use virXMLProp(OnOff|YesNo) in virDomainNumaDefParseXML storage_adapter_conf: Use virXMLProp(OnOff|YesNo) in virStorageAdapterParseXMLFCHost storage_conf: Use virXMLProp(OnOff|YesNo) in virStoragePoolDefParseSource src/conf/backup_conf.c | 32 +- src/conf/device_conf.c | 10 +- src/conf/domain_conf.c | 791 +++++++++----------------------- src/conf/network_conf.c | 15 +- src/conf/numa_conf.c | 13 +- src/conf/storage_adapter_conf.c | 17 +- src/conf/storage_adapter_conf.h | 2 +- src/conf/storage_conf.c | 16 +- src/util/virxml.c | 74 +++ src/util/virxml.h | 7 + 10 files changed, 314 insertions(+), 663 deletions(-) -- 2.26.2

[PATCH v2] bhyve: add <os firmware='efi'> support
by Roman Bogorodskiy 18 Mar '21

18 Mar '21

Implement "<os firmware='efi'>" support for bhyve driver. As there are not really lot of options, try to find "BHYVE_UEFI.fd" firmware which is installed by the sysutils/uefi-edk2-bhyve FreeBSD port. If not found, just use the first found firmware in the firmwares directory (which is configurable via config file).

If we attempt to exit libvirtd before this init thread has completed, we'll try to free the device list while accessing it from the other thread. In order to guarantee that this init thread is not accessing the device list when we're cleaning up the nodedev driver, make it joinable and wait for it to finish before proceding with the cleanup. This is similar to how we handle the udev event handler thread. The separate initialization thread was added in commit 9f0ae0b1. https://bugzilla.redhat.com/show_bug.cgi?id=1933590 Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com> --- src/node_device/node_device_udev.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/src/node_device/node_device_udev.c b/src/node_device/node_device_udev.c index fe25f8235e..010ebf4e74 100644 --- a/src/node_device/node_device_udev.c +++ b/src/node_device/node_device_udev.c @@ -66,6 +66,9 @@ struct _udevEventData { virCond threadCond; bool threadQuit; bool dataReady; + + /* init thread */ + virThread initThread; }; static virClassPtr udevEventDataClass; @@ -1660,6 +1663,7 @@ nodeStateCleanup(void) priv->threadQuit = true; virCondSignal(&priv->threadCond); virObjectUnlock(priv); + virThreadJoin(&priv->initThread); virThreadJoin(&priv->th); } @@ -1995,7 +1999,6 @@ nodeStateInitialize(bool privileged, { udevEventDataPtr priv = NULL; struct udev *udev = NULL; - virThread enumThread; if (root != NULL) { virReportError(VIR_ERR_INVALID_ARG, "%s", @@ -2103,7 +2106,7 @@ nodeStateInitialize(bool privileged, if (udevSetupSystemDev() != 0) goto cleanup; - if (virThreadCreateFull(&enumThread, false, nodeStateInitializeEnumerate, + if (virThreadCreateFull(&priv->initThread, true, nodeStateInitializeEnumerate, "nodedev-init", false, udev) < 0) { virReportSystemError(errno, "%s", _("failed to create udev enumerate thread")); -- 2.26.2

[PATCH] virxml: Fix possible memory leak in virXMLNodeContentString()
by Kristina Hanicova 18 Mar '21

18 Mar '21

Previously, if xml node passed to the virXMLNodeContentString() was not of type XML_ELEMENT_NODE, @ret could have caused a memory leak because xmlNodeGetContent() works for other types of nodes as well.
