XML shmem name will not include character '/', and will not be equal to strings "." or "..", as shmem name is used in a path. https://bugzilla.redhat.com/show_bug.cgi?id=1192400 --- Changes in V2 - Added error reports - Error situation will happen only if shmem name is equal to "." or "..", however their occurence in a name compromised of more characters is allowed. src/conf/domain_conf.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 7ab2953d83..6b34c17de4 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -6107,6 +6107,8 @@ virDomainDefLifecycleActionValidate(const virDomainDef *def) static int virDomainDefValidateInternal(const virDomainDef *def) { + size_t i; + if (virDomainDefCheckDuplicateDiskInfo(def) < 0) return -1; @@ -6136,6 +6138,26 @@ virDomainDefValidateInternal(const virDomainDef *def) return -1; } + for (i = 0; i < def->nshmems; i++) { + if (strchr(def->shmems[i]->name, '/')) { + virReportError(VIR_ERR_XML_ERROR, "%s", + _("shmem name cannot include '/' character")); + return -1; + } + + if (STREQ(def->shmems[i]->name, ".")) { + virReportError(VIR_ERR_XML_ERROR, "%s", + _("shmem name cannot be equal to '.'")); + return -1; + } + + if (STREQ(def->shmems[i]->name, "..")) { + virReportError(VIR_ERR_XML_ERROR, "%s", + _("shmem name cannot be equal to '..'")); + return -1; + } + } + if (virDomainDefLifecycleActionValidate(def) < 0) return -1; -- 2.17.1
