[libvirt] [PATCH] Change security driver APIs to use virDomainDefPtr instead of virDomainObjPtr

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; When sVirt is integrated with the LXC driver, it will be neccessary to invoke the security driver APIs using only a virDomainDefPtr since the lxc_container.c code has no virDomainObjPtr available. Aside from two functions which want obj->pid, every bit of the security driver code only touches obj->def. So we don't need to pass a virDomainObjPtr into the security drivers, a virDomainDefPtr is sufficient. Two functions also gain a 'pid_t pid' argument. * src/qemu/qemu_driver.c, src/qemu/qemu_hotplug.c, src/qemu/qemu_migration.c, src/qemu/qemu_process.c, src/security/security_apparmor.c, src/security/security_dac.c, src/security/security_driver.h, src/security/security_manager.c, src/security/security_manager.h, src/security/security_nop.c, src/security/security_selinux.c, src/security/security_stack.c: Change all security APIs to use a virDomainDefPtr instead of virDomainObjPtr --- src/qemu/qemu_driver.c | 10 +- src/qemu/qemu_hotplug.c | 28 ++-- src/qemu/qemu_migration.c | 12 +- src/qemu/qemu_process.c | 24 ++-- src/security/security_apparmor.c | 136 ++++++++++---------- src/security/security_dac.c | 91 +++++++------- src/security/security_driver.h | 36 +++--- src/security/security_manager.c | 40 +++--- src/security/security_manager.h | 36 +++--- src/security/security_nop.c | 36 +++--- src/security/security_selinux.c | 260 +++++++++++++++++++------------------- src/security/security_stack.c | 44 ++++--- 12 files changed, 381 insertions(+), 372 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 6cfdd1d..6e001ce 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -3096,7 +3096,7 @@ qemuDomainScreenshot(virDomainPtr dom, } unlink_tmp = true;
