I'm sponsoring this fast-track request for myself. The timer is set
to 06/15/2009.
The Solaris Bridging project (PSARC 2008/055) has not yet integrated.
In order to support changes encountered in design review, this
proposal modifies that previous project and has the same Minor release
binding.
The primary changes (in summary) are:
- Self-protection
A self-protection mechanism for the forwarding table was added to
avoid both memory explosion and some data theft threats. Bridges
by default forward to all interfaces, so avoiding theft generally
means deleting entries.
- Optional installation
The bridging packages are optional, so dladm must return an error
if the user tries to create a bridge and the optional software
isn't installed. A generic Consolidation Private
DLADM_STATUS_OPTMISSING error is added for this (and for any
future similar cases). The packages are placed into a new
SUNWCbridge cluster.
- /dev/bridge/ is gone
This is no longer needed; Clearview's /dev/net/ observability
nodes serve all the needs of the bridging design.
- Added accidentally-omitted long option names for dladm
- Dynamic reconfiguration now supported
New Project Private SUNW_bridge_rcm.so module added.
- IEEE STP "mcheck" supported
- Crossbow polling disabled on bridged links
- MTU and link up/down handling detailed
The "materials" directory in the case contains these files:
bridging-design.pdf - current, reviewed design document (1.3)
bridging-spec.txt - updated architecture document
bridging-spec.diff - diffs versus final 2008/055 architecture
