Rustam Kovhaev 19184bd06f KVM: fix memory leak in kvm_io_bus_unregister_dev() ... [ Upstream commit f65886606c2d3b562716de030706dfe1bea4ed5e ] when kmalloc() fails in kvm_io_bus_unregister_dev(), before removing the bus, we should iterate over all other devices linked to it and call kvm_iodevice_destructor() for them Fixes: 90db10434b ("KVM: kvm_io_bus_unregister_dev() should never fail") Cc: stable@vger.kernel.org Reported-and-tested-by: syzbot+f196caa45793d6374707@syzkaller.appspotmail.com Link: https://syzkaller.appspot.com/bug?extid=f196caa45793d6374707 Signed-off-by: Rustam Kovhaev <rkovhaev@gmail.com> Reviewed-by: Vitaly Kuznetsov <vkuznets@redhat.com> Message-Id: <20200907185535.233114-1-rkovhaev@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-09-26 18:01:28 +02:00
