New Features in Version 4.1.1


Version 4.1.1 is a maintenance release.  No new features have been added.



Bugs fixed in Version 4.1.1


The following bugs have been fixed in Version 4.1.1:


SAND, GateD Errors Require User Intervention On Rebel Routers At Boot-Time

Version 4.1.1 fixes a bug in the configuration checking code for SAND and GateD.
Rebel Routers running Version 4.1.0 with errors in the SAND or GateD configurations
would pause waiting for users to press "Q" after viewing error messages at boot.
The error check is bypassed in Version 4.1.1 at boot time.


Interaction Between Quad Ethernet and PCI 520 Series Cards

Under Version 4.1.0, routers with Starfire chipset based quad Ethernet boards
and PCI 520 series cards experienced a serious interaction problem.  This
code incompatibility would cause these routers to lock up under specific
conditions.  Previous versions of Enterprise Linux are unaffected by this
problem.  Version 4.1.1 fixes the interaction problem between these boards.


menuEngine Does Not Exit On Abnormal Connection Termination

Under abnormal logout and connection loss conditions, previous software
revisions would not properly exit the menu process.  This process would use
a significant portion of available CPU cycles, potentially decreasing routing
performance.  Version 4.1.1 correctly handles these abnormal conditions and
closes the menu process on all logouts and connection loss events.


Ethernet Reload Problem Corrected

Ethernet devices now reload properly when moving IP addresses between Ethernet
interfaces.  Previous releases would not shut down interface whose IP address
had been removed.  Version 4.1.1 ensures that Ethernet devices are shut down
properly when IP addresses are removed.
