Re: [libvirt] Fix a failure to restore SELinux label for character devices

The code in SELinuxRestoreSecurityChardevLabel() was trying to use SELinuxSetFilecon directly for devices or file types while it should really use SELinuxRestoreSecurityFileLabel encapsulating routine, which avoid various problems like resolving symlinks, making sure he file exists and work around NFS problems Daniel diff --git a/src/security/security_selinux.c b/src/security/security_selinux.c index 936a1a6..996177a 100644 --- a/src/security/security_selinux.c +++ b/src/security/security_selinux.c @@ -694,9 +694,10 @@ SELinuxRestoreSecurityChardevLabel(virDomainObjPtr vm, switch (dev->type) { case VIR_DOMAIN_CHR_TYPE_DEV: case VIR_DOMAIN_CHR_TYPE_FILE: - ret = SELinuxSetFilecon(dev->data.file.path, secdef->imagelabel); + if (SELinuxRestoreSecurityFileLabel(dev->data.file.path) < 0) + goto done; + ret = 0; break; - case VIR_DOMAIN_CHR_TYPE_PIPE: if ((virAsprintf(&out, "%s.out", dev->data.file.path) < 0) || (virAsprintf(&in, "%s.in", dev->data.file.path) < 0)) {
