+Subject: [PATCH 2/3] blockjob: avoid memory leak during block pivot
+
+Valgrind caught a memory leak:
+
+==2018== 9 bytes in 1 blocks are definitely lost in loss record 143 of 927
+==2018== at 0x4A0645D: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)

+==2018== by 0x51DC6B2: virDomainBlockCommit (libvirt.c:20092)
+
+I traced it to the fact that blockcopy and blockcommit end up
+reparsing a backing chain on pivot, but the chain parsing code
+doesn't gracefully handle the case where the backing file is
+already known.
+
+I'm not exactly sure when this was introduced, but suspect that the
+refactoring in commit 9944b71 and friends that moved towards probing
+in-place rather than into a temporary structure are part of the cause.

+Subject: [PATCH 3/3] blockjob: fix use-after-free in blockcopy
+
+Commit febf84c2 tried to delay in-memory modification of the actual
+domain disk structure until after the qemu event was received.
+However, I missed that the code for block pivot had been temporarily
+setting disk->src = disk->mirror prior to the qemu command, in order
+to label the backing chain of a reused external blockcopy disk;
+and calls into qemu while still in that state before finally undoing
+things at the cleanup label. Since the qemu event handler then does:
+ virStorageSourceFree(disk->src);
+ disk->src = disk->mirror;
+we have the sad race that a fast enough qemu event can cause a leak of
+the original disk->src, as well as a use-after-free of the disk->mirror
+contents, bad enough to crash libvirtd in some of my test runs, even
+though the common case of the qemu event being much later won't trip
+the race.
+
+I'll go wear the brown paper bag of shame, for introducing a crasher
+in between rc1 and rc2 of the freeze for 1.2.7 :( My only
+consolation is that virDomainBlockJobAbort requires the domain:write
+ACL, so it is not a CVE.
+
+The valgrind report when the race occurs looks like:
+
+==25612== Invalid read of size 4
