This simplifies several callers that were repeating checks already guaranteed by util.c, and makes other callers more robust to now reject directories. remote_driver.c was over-strict - access(,R_OK) is only needed to execute a script file; a binary only needs access(,X_OK) (besides, it's unusual to see a file with x but not r permissions, whether script or binary). * cfg.mk (sc_prohibit_access_xok): New syntax-check rule. (exclude_file_name_regexp--sc_prohibit_access_xok): Exempt one use. * src/network/bridge_driver.c (networkStartRadvd): Fix offenders. * src/qemu/qemu_capabilities.c (qemuCapsProbeMachineTypes) (qemuCapsInitGuest, qemuCapsInit, qemuCapsExtractVersionInfo): Likewise. * src/remote/remote_driver.c (remoteFindDaemonPath): Likewise. * src/uml/uml_driver.c (umlStartVMDaemon): Likewise. * src/util/hooks.c (virHookCheck): Likewise.

Bug https://bugzilla.redhat.com/show_bug.cgi?id=689374 reported libvirtd crash during error dispatch. The reason is that libvirtd uses remoteDispatchConnError() with non-NULL conn parameter which means that virConnGetLastError() is used instead of its thread safe replacement virGetLastError(). So when several libvirtd threads are reporting errors at the same time, the errors can get mixed or corrupted or in case of bad luck libvirtd itself crashes. Since Daniel B. is going to rewrite this code from scratch on top of his RPC infrastructure, I tried to come up with a minimal fix. Thus, remoteDispatchConnError() now just ignores its conn argument and always calls virGetLastError(). However, several callers had to be touched as well, since no libvirt API is allowed to be called before dispatching the error. Doing so would reset the error and we would have nothing to dispatch. As a result of that, the code is not very nice but that doesn't really make daemon/remote.c worse than it is now :-) And it will all die soon, which is good. The bug report also contains a reproducer in C which detects both mixed up error messages and libvirtd crash. Before this patch, I was able to crash libvirtd in about 20 seconds up to 3 minutes depending on number of CPU cores (more is better) and luck.

Problem: "parser.head" is not NULL even if it's free'ed by "virJSONValueFree", returning "parser.head" when "virJSONValueFromString" fails will cause unexpected errors (libvirtd will crash sometimes), e.g. In function "qemuMonitorJSONArbitraryCommand": if (!(cmd = virJSONValueFromString(cmd_str))) goto cleanup; if (qemuMonitorJSONCommand(mon, cmd, &reply) < 0) goto cleanup; ...... cleanup: virJSONValueFree(cmd); It will continues to send command to monitor even if "virJSONValueFromString" is failed, and more worse, it trys to free "cmd" again. Crash example: {"error":{"class":"QMPBadInputObject","desc":"Expected 'execute' in QMP input","data":{"expected":"execute"}}} {"error":{"class":"QMPBadInputObject","desc":"Expected 'execute' in QMP input","data":{"expected":"execute"}}} error: server closed connection: error: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Connection refused error: failed to connect to the hypervisor This fix is to: 1) return NULL for failure of "virJSONValueFromString", 2) and it seems "virJSONValueFree" uses incorrect loop index for type of "VIR_JSON_TYPE_OBJECT", fix it together. * src/util/json.c

This patch introduces PREASSOCIATE-RR during incoming VM migration on the destination host. This is similar to the usage of PREASSOCIATE during migration in 8021qbg libvirt code today. PREASSOCIATE-RR is a VDP operation. With the latest at IEEE, 8021qbh will need to support VDP operations. A corresponding enic driver patch to support PREASSOCIATE-RR for 8021qbh will be posted for net-next-2.6 inclusion soon.

由 Eric Blake 提交于
This is also a bug fix - on the error path, qemu_hotplug would leave the configfd file leaked into qemu. At least the next attempt to hotplug a PCI device would reuse the same fdname, and when the qemu getfd monitor command gets a new fd by the same name as an earlier one, it closes the earlier one, so there is no risk of qemu running out of fds. * src/qemu/qemu_monitor.h (qemuMonitorAddDeviceWithFd): New prototype. * src/qemu/qemu_monitor.c (qemuMonitorAddDevice): Move guts... (qemuMonitorAddDeviceWithFd): ...to new function, and add support for fd passing. * src/qemu/qemu_hotplug.c (qemuDomainAttachHostPciDevice): Use it to simplify code. Suggested by Daniel P. Berrange.

qemu_monitor was already returning -1 and setting errno to EINVAL on any attempt to send an fd without a unix socket, but this was a silent failure in the case of qemuDomainAttachHostPciDevice. Meanwhile, qemuDomainAttachNetDevice was doing some sanity checking for a better error message; it's better to consolidate that to a central point in the API. * src/qemu/qemu_hotplug.c (qemuDomainAttachNetDevice): Move sanity checking... * src/qemu/qemu_monitor.c (qemuMonitorSendFileHandle): ...into central location.

This is detailed in: https://bugzilla.redhat.com/show_bug.cgi?id=688957 Since radvd is executed by daemonizing it, the attempt to exec the radvd binary doesn't happen until after libvirtd has already received an exit code from the intermediate forked process, so no error is detected or logged by __virExec(). We can't require radvd as a prerequisite for the libvirt package (many installations don't use IPv6, so they don't need it), so instead we add in a check to verify there is an executable radvd binary prior to trying to exec it.
