[libvirt] [PATCH 2/2] parallels: Resolve some resource leaks

Be sure to VIR_FREE(accel) and moved virDomainVideoDefFree() within no_memory label to be consistent Resolve resource leak in parallelsApplyIfaceParams() when the 'oldnet' is allocated locally. --- src/parallels/parallels_driver.c | 30 +++++++++++++++++++----------- 1 file changed, 19 insertions(+), 11 deletions(-) diff --git a/src/parallels/parallels_driver.c b/src/parallels/parallels_driver.c index ea193af..8beab2c 100644 --- a/src/parallels/parallels_driver.c +++ b/src/parallels/parallels_driver.c @@ -304,8 +304,9 @@ parallelsAddVideoInfo(virDomainDefPtr def, virJSONValuePtr value) no_memory: virReportOOMError(); -cleanup: + VIR_FREE(accel); virDomainVideoDefFree(video); +cleanup: return -1; } @@ -1809,58 +1810,58 @@ static int parallelsApplyIfaceParams(parallelsDomObjPtr pdom, if (!create && oldnet->type != newnet->type) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Changing network type is not supported")); - return -1; + goto error; } if (!STREQ_NULLABLE(oldnet->model, newnet->model)) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Changing network device model is not supported")); - return -1; + goto error; } if (!STREQ_NULLABLE(oldnet->data.network.portgroup, newnet->data.network.portgroup)) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Changing network portgroup is not supported")); - return -1; + goto error; } if (!virNetDevVPortProfileEqual(oldnet->virtPortProfile, newnet->virtPortProfile)) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Changing virtual port profile is not supported")); - return -1; + goto error; } if (newnet->tune.sndbuf_specified) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Setting send buffer size is not supported")); - return -1; + goto error; } if (!STREQ_NULLABLE(oldnet->script, newnet->script)) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Setting startup script is not supported")); - return -1; + goto error; } if (!STREQ_NULLABLE(oldnet->filter, newnet->filter)) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Changing filter params is not supported")); - return -1; + goto error; } if (newnet->bandwidth != NULL) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Setting bandwidth params is not supported")); - return -1; + goto error; } for (i = 0; i < sizeof(newnet->vlan); i++) { if (((char *)&newnet->vlan)[i] != 0) { virReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s", _("Setting vlan params is not supported")); - return -1; + goto error; } } @@ -1902,15 +1903,22 @@ static int parallelsApplyIfaceParams(parallelsDomObjPtr pdom, is_changed = true; } + if (create) + VIR_FREE(oldnet); + if (!create && !is_changed) { /* nothing changed - no need to run prlctl */ return 0; } if (virCommandRun(cmd, NULL)) - return -1; + goto error; return 0; +error: + if (create) + VIR_FREE(oldnet); + return -1; } static int -- 1.7.11.7
