Solaris Hotplug Framework (2008/181)
IAM
======
Name: Solaris Hotplug Framework
Submitter: Colin Zou
Owner: Garrett D'Amore
Intern: Phi Tran
Interest: govinda.tatti at sun.com
Status: submitted
Exposure: open
SUMMARY
=======
The main goal of this project is to provide a generic common
Solaris
hotplug framework, a foundation which can support hotplug
functionality
for any hotpluggable bus. The key features include:
o A state machine based, bus independent hotplug framework
which will
interact with other frameworks (such as PM, FMA and Devfs).
It will
manage the hotplug slot states, interact with bus specific
hotplug
controller modules and configuators (including kernel driven
auto-configuration), deliver hotplug events through the Device
Contract, LDI and Sysevent frameworks, and handle all user
initiated
hotplug operations.
o Well defined, common interfaces to the physical and virtual
hotplug
controller drivers. This will simplify writing a new driver with
hotplug controller functionality, because drivers can
implement their
hotplug requirements by calling into the new framework.
o DDI hotplug interfaces for leaf device drivers to support
features
such as surprise removal, hot replacement, dynamic resource
re-balance etc., and framework notification of any asynchronous
events such as
errors and brute force user operations.
At the same time, the new hotplug framework will be
compatible with
existing DDI compliant leaf device drivers.
o A new resource allocator, which will manage bus resources through
device tree and provides support for dynamic resource re-balance
operations.
o Generic hotplug management interfaces, so that various types of
management applications, including GUIs, can be written to these
interfaces. The project will deliver a new GUI based hotplug tool
and may also modify cfgadm or deliver a new command line
(CLI) tool.
o A hotplug daemon to deliver hotplug events to all hotplug aware
applications and userland modules through Device Contract and
Sysevent frameworks.
o Support for PCI (SHPC based) and PCI Express hotplug
functionality
under the new Solaris Hotplug Framework. In addition, a set
of new
features will be supported such as surprise removal, hot
replacement,
power fault, hotplug FMA, and hotplug operation on an individual
device or function in addition to slot or attachment point.
Please note that the old or proprietary hotplug functionality
will
not be migrated to new hotplug framework.
o Support hotplug under virtual environment like IOV, Ldoms,
Xen etc.
Supporting hotplug for virtualized devices requires a virtual
hotplug
controller driver. These virtual HPC drivers may use different
interfaces or methods for accessing physical/IOV compliant
devices
(v/s para-virtualized (PV) devices).
The project will be implemented and delivered in multiple
phases due to
the priority of some key features & time constraints. For
clarification
of the big picture, all phases are presented here. However, the
scope of ARC review requested for this case is limited to the
first phase. The
full definition of other phases including resources and
schedules are
not known at this time. Subsequent ARC cases will be submitted when
subsequent project phases commence.
o Phase-I:
Support existing standard PCI, Native and ACPI based PCI Express
hotplug functionality under the new Solaris Hotplug Framework
along
with several new key features such as:
- New hotplug DDI interfaces for leaf drivers
- New resource allocator interfaces
- Kernel initiated auto-configuration
- Hotplug events through device contract, LDI and sysevent
frameworks
- Dynamic resource re-balance
- Surprise removal, hot replacement, hotplug FMA
- Modified cfgadm or new userland admin tool (CLI)
o Phase-II:
- Support hotplug under virtual environments such as IOV,
Ldoms, Xen
- Support for a GUI admin tool
Please note that the virtual hotplug support may get delivered as
part of phase-I if required (based on its priority and resource
availability).
o Phase-III:
- Support for Express Card
ISSUES
======
gw-99 Sorry for the late and parochial issues, but I'm still officially
on sabbatical. And I still seem to be the first in the fine.
gw-1 How does this play with devkit, device allocation, SunRay?
gw-2 This project seems to require administrative audit, yet there
is no mention. See the 20 Questions (and Solaris Audit Policy).
gw-3 What is the method context for the service?
Are there any properties? Is this enabled by the profile?
Is there any reason to ever disable it manually?
gw-4 Root is not a privilege (nor is uid 0 special) why isn't
this authorization driven? Just how are you doing access
control? Access control decisions also require audit.
gw-5 I'm dubious about the Patch binding. Verify with the Solaris
Evaluations and Trusted Extensions project teams that this is
appropriate for a Patch. The manager is Craig Payne.
gw-6 What would be the meaning of "remote clients". INET sockets
should be avoided as they add an attack vector. I'm still
dubious about doors being complex.
gw-7 What is the compelling reason that RBAC must be postponed?
How is the project complete without meeting the Solaris
Policies? Is a PAC waver going to be requested?
gw-99a userland: RBAC is not authentication, in this case it is
authorization based access control.
THE NEXT STEP

work with Owner and return for Commitment

RBridges: Routing Bridges (2007/596)
IAM
====
Name: RBridges: Routing Bridges
Submitter: James Carlson
Owner: James Carlson
Intern: Sebastien Roy
Interest:
Status: commitment scheduled 06/17/2009
Comment: inception held 12/12/2007
Exposure: open
SUMMARY
=======
The RBridges product provides Solaris with bridging
functionality, including a new protocol (under development in
the IETF) that will replace Spanning Tree Protocol, and also
with IS-IS routing for IP networks.
ISSUES
=======
PSARC 2007/596: RBridges: Routing Bridges
Submitter: James Carlson
Owner: NONE
Issues for inception (12/12/2007):
kb-01 The crossbow project is exposing a MAC client API for adding extra
packet receivers (such snoop instances) and sumit packets for
transmission at the MAC level (not DLS, which is being removed
from
the datapath). RBridges should communicate with to the Crossbow
project to see if the MAC client API is sufficient for RBriges
needs.
