If "strdup (d->d_name)" fails with "i" > 0, then both "p" and "ret->guestfs_int_dirent_list_val" are non-null pointers, but the latter is no more valid (since "p" is the new realloc'ed buffer). Hence, trying to free both will access to invalid memory. Make sure to free only one of them, "p" if not null or

Starting with libguestfs 1.22, "attach methods" will be known as "backends" (one word, no space or hyphen). There are new APIs 'guestfs_set_backend', 'guestfs_get_backend', and a new environment variable 'LIBGUESTFS_BACKEND'. Furthermore, the default backend, running qemu directly, is now called "direct" instead of "appliance". (Note that distros can change the default by compiling with ./configure --with-default-backend=..., and Fe...

I download libguestfs from github and fetch to the *origin master*. I tried to build libguestfs in my own linux distro and I followd the http://libguestfs.org/guestfs-building.1.html#using-a-prebuilt-binary-appliance to replace with supermin I download the appliance-1.30.1.tar.xz and appliance-1.30.1.tar.xz.sig and extract the tarball to /home/user/appliance and export

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.
