In order to have multiple security drivers hidden under one
virSecurity* call, we have virSecurityStack driver which holds a
list of registered security drivers and for every virSecurity*
call it iterates over the list and calls corresponding callback
in real security drivers. For instance, for
virSecurityManagerSetAllLabel() it calls
domainSetSecurityAllLabel callback sequentially in NOP, DAC and
(possibly) SELinux or AppArmor drivers. This works just fine if
the callback from every driver returns success. Problem arises
when one of the drivers fails. For instance, aforementioned
SetAllLabel() succeeds for DAC but fails in SELinux in which
case all files that DAC relabelled are now owned by qemu:qemu (or
whomever runs qemu) and thus permissions are leaked. This is even
more visible with XATTRs which remain set for DAC.
The solution is to perform a rollback on failure, i.e. call
opposite action on drivers that succeeded.
I'm providing rollback only for set calls and intentionally
omitting restore calls for two reasons:
1) restore calls are less likely to fail (they merely remove
XATTRs and chown()/setfilecon() file - all of these operations
succeeded in set call),
2) we are not really interested in restore failures - in a very
few places we check for retval of a restore function we do so
only to print a warning.

In near future we will need to walk through the list of internal
drivers in reversed order. The simplest solution is to turn
singly linked list into a doubly linked list.
We will not need to start from the end really, so there's no tail
pointer kept.

In upcoming commits, virSecurityManagerSetAllLabel() will perform
rollback in case of failure by calling
virSecurityManagerRestoreAllLabel(). But in order to do that, the
former needs to have @migrated argument so that it can be passed
to the latter.

The usleep function was missing on older mingw versions, but we can rely
on it existing everywhere these days. It may only support times upto 1
second in duration though, so we'll prefer to use g_usleep instead.
The commandhelper program is not changed since that can't link to glib.
Fortunately it doesn't need to build on Windows platforms either.

g_strerror is offers the safety/correctness benefits of strerror_r, with
the API design convenience of strerror.
Use of virStrerror should be eliminated through the codebase in favour
of g_strerror.
commandhelper.c is a special case as its a tiny single threaded test
program, not linked to glib, so it just uses traditional strerror().

Converting from virObject to GObject is reasonably straightforward,
as illustrated by this patch for virIdentity
In the header file
- Remove
typedef struct _virIdentity virIdentity
- Add
#define VIR_TYPE_IDENTITY virIdentity_get_type ()
G_DECLARE_FINAL_TYPE (virIdentity, vir_identity, VIR, IDENTITY, GObject);
Which provides the typedef we just removed, and class
declaration boilerplate and various other constants/macros.
In the source file
- Change 'virObject parent' to 'GObject parent' in the struct
- Remove the virClass variable and its initializing call
- Add
G_DEFINE_TYPE(virIdentity, vir_identity, G_TYPE_OBJECT)
which declares the instance & class constructor functions
- Add an impl of the instance & class constructors
wiring up the finalize method to point to our dispose impl
In all files
- Replace VIR_AUTOUNREF(virIdentityPtr) with g_autoptr(virIdentity)
- Replace virObjectRef/Unref with g_object_ref/unref. Note
the latter functions do *NOT* accept a NULL object where as
libvirt's do. If you replace g_object_unref with g_clear_object
it is NULL safe, but also clears the pointer.
