      util: introduce cgroup v2 files · b4ddf5ae
      由 Pavel Hrdina 提交于 
      Place cgroup v2 backend type before cgroup v1 to make it obvious
that cgroup v2 is preferred implementation.

Following patches will introduce support for hybrid configuration
which will allow us to use both at the same time, but we should
prefer cgroup v2 regardless.

      util: avoid symbol clash between json libraries · ce3c6ef6
      由 Daniel P. Berrangé 提交于 
      The jansson and json-glib libraries both export symbols with a json_
name prefix and json_object_iter_next() clashes between them.

Unfortunately json-glib is linked in by GTK, so any app using GTK and
libvirt will get a clash, resulting in SEGV. This also affects the NSS
module provided by libvirt

Instead of directly linking to jansson, use dlopen() with the RTLD_LOCAL
flag which allows us to hide the symbols from the application that loads
libvirt or the NSS module.

Some preprocessor black magic and wrapper functions are used to redirect
calls into the dlopen resolved symbols.

      build: prevent unloading of dlopen'd modules · 71feef92
      由 Daniel P. Berrangé 提交于 
      We previously added "-z nodelete" to the build of libvirt.so to prevent
crashes when thread local destructors run which point to a code that
has been dlclose()d:

  Date:   Thu Sep 1 17:57:06 2011 +0100

      Prevent crash from dlclose() of libvirt.so

The libvirtd loadable modules can suffer from the same problem if they
were ever unloaded. Fortunately we don't ever call dlclose() on them,
but lets add a second layer of protection by linking them with the
"-z nodelete" flag. While we're doing this, lets add a third layer of
protection by passing RTLD_NODELETE to dlopen().

      Prevent crash from dlclose() of libvirt.so

We forgot to copy this protection into the libvirt-qemu.so, libvirt-lxc.so
and libvirt-admin.so libraries when we introduced them.
