Re: [libvirt] [PATCH] qemu_driver.c: avoid double free on error path

Note that there's nearly identical code in the same file where there is already an "event = NULL;" statement right after two identical lines. >From 69f3c74b6cdc36fb4958f4c9cc2d4497a03d40c1 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com&gt; Date: Mon, 14 Dec 2009 15:55:19 +0100 Subject: [PATCH] qemu_driver.c: avoid double free on error path * src/qemu/qemu_driver.c (qemudDomainMigrateFinish2): Set "event" to NULL after qemuDomainEventQueue frees it, so a subsequent free (after endjob label) upon qemuMonitorStartCPUs failure does not cause a double free. --- src/qemu/qemu_driver.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 34fa582..43f7927 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -7668,6 +7668,7 @@ qemudDomainMigrateFinish2 (virConnectPtr dconn, VIR_DOMAIN_EVENT_DEFINED_UPDATED); if (event) qemuDomainEventQueue(driver, event); + event = NULL; } qemuDomainObjPrivatePtr priv = vm->privateData; --
