[libvirt] [PATCH] Fix default value of security label 'relabel' attribute

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; When no <seclabel> is present in the XML, the virDomainSeclabelDef struct is left as all zeros. Unfortunately, this means it gets setup as type=dynamic, with relabel=no, which is an illegal combination. Change the 'bool relabel' attribute in virDomainSeclabelDef to the inverse 'bool norelabel' so that the default initialization is sensible * src/conf/domain_conf.c, src/conf/domain_conf.h, src/security/security_apparmor.c, src/security/security_selinux.c: Replace 'relabel' with 'norelabel' --- src/conf/domain_conf.c | 18 +++++++++--------- src/conf/domain_conf.h | 2 +- src/security/security_apparmor.c | 8 ++++---- src/security/security_selinux.c | 20 ++++++++++---------- 4 files changed, 24 insertions(+), 24 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 109a947..b74ab4d 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -5076,25 +5076,25 @@ virSecurityLabelDefParseXML(const virDomainDefPtr def, VIR_SECURITY_LABEL_BUFLEN-1, ctxt); if (p != NULL) { if (STREQ(p, "yes")) { - def->seclabel.relabel = true; + def->seclabel.norelabel = false; } else if (STREQ(p, "no")) { - def->seclabel.relabel = false; + def->seclabel.norelabel = true; } else { virDomainReportError(VIR_ERR_XML_ERROR, _("invalid security relabel value %s"), p); goto error; } if (def->seclabel.type == VIR_DOMAIN_SECLABEL_DYNAMIC && - !def->seclabel.relabel) { + def->seclabel.norelabel) { virDomainReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("dynamic label type must use resource relabeling")); goto error; } } else { if (def->seclabel.type == VIR_DOMAIN_SECLABEL_STATIC) - def->seclabel.relabel = false; + def->seclabel.norelabel = true; else - def->seclabel.relabel = true; + def->seclabel.norelabel = false; } /* Only parse label, if using static labels, or @@ -5114,7 +5114,7 @@ virSecurityLabelDefParseXML(const virDomainDefPtr def, } /* Only parse imagelabel, if requested live XML with relabeling */ - if (def->seclabel.relabel && + if (!def->seclabel.norelabel && !(flags & VIR_DOMAIN_XML_INACTIVE)) { p = virXPathStringLimit("string(./seclabel/imagelabel[1])", VIR_SECURITY_LABEL_BUFLEN-1, ctxt); @@ -9890,15 +9890,15 @@ char *virDomainDefFormat(virDomainDefPtr def, (flags & VIR_DOMAIN_XML_INACTIVE)) { virBufferAsprintf(&buf, " <seclabel type='%s' model='%s' relabel='%s'/>\n", sectype, def->seclabel.model, - def->seclabel.relabel ?
