Dangling pointer. One ref, two unrefs probably.
I'm redoing the series according to Peter's request, it could fix it
Hi.
Ok. Back to the bug with this patch. The initial problem with this patch is
that "make check" fails.
Please help with subpages.
It turned out that tests use MALLOC_PERTURB_ which is normally off. Who
does not know - this is a way to tell glibc to fill released memory with
some value and then
Fails on qtest_init() in tests/libqtest.c, "Broken pipe". I cannot easily
see what is wrong here with this patch but it is 100% reproducible on x86_64
:(

Hi!
I do not know how (yet) but this patch breaks qtest on x86 (I bisected it):
make check-qtest V=1
QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64
MALLOC_PERTURB_=${MALLOC_PERTURB_:-$((RANDOM % 255 + 1))} gtester -k

Add ref/unref calls at the following places:
- places where memory regions are stashed by a listener and
used outside the BQL (including in Xen or KVM).
- memory_region_find callsites
- creation of aliases and containers (only the aliased/contained
region gets a reference to avoid loops)
-
