Solution Type: Sun Alert
Solution 237404 : Installing a Kernel patch or certain Solaris
Trusted Extensions patches may cause desktop login failures for
systems configured with Solaris Trusted Extensions enabled
Bug ID: 6691776, 6687697
Product
Solaris 10 Operating System
Date of Resolved Release: 02-May-2008
SA Document Body
Installing a Kernel patch or certain Solaris Trusted Extensions patches may
cause desktop login failures for systems configured with Solaris Trusted
Extensions enabled
1. Impact
Solaris 10 systems which have Solaris Trusted Extensions enabled which
install kernel patch 127127-11, 127128-11 or certain Solaris Trusted
Extensions patches may not be able to complete the login process. The
desktop environment will fail to start.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
Case 1: Solaris 10 with patch 127127-11 (or later) and without patches
126363-03, 123611-03, and 126365-07
Case 2: Solaris 10 with patch 126365-04 (or later) and without patch
123611-03
x86 Platform
Case 1: Solaris 10 with patch 127128-11 (or later) and without patches
126364-04, 123612-03, and 126366-07
Case 2: Solaris 10 with patch 126366-04 (or later) and without patch
123612-03
Note: Only systems configured with Solaris Trusted Extensions and
matching one of the configurations of patches described above are
impacted by this issue.
To determine if a system is configured with Solaris Trusted
Extensions, the following command can be run:
$ svcs /system/labeld
STATE STIME FMRI
online 07:08:09
svc:/system/labeld:default
If the system is configured with Solaris Trusted Extensions, the
"labeld" service will have an instance in the online state.
3. Symptoms
Installing the affected patches onto vulnerable systems with the
patches as defined in section 2 above will cause the desktop
environment to fail to start.
For patches listed in Contributing Factors for Case 1 (either SPARC or
x86): when the systems boot to multiuser mode, there will be a message
indicating the Xserver has failed to start or the system will return a
blank terminal only.
For patches listed in Contributing Factors for Case 2 (either SPARC or
x86): the user is able to commence the login dialog, the "Message Of
The Day" and the Session Clearance Selection dialog, but after that
the desktop stays frozen at the initial phase.
4. Workaround
To avoid this issue, patches must be installed in the following order:
For Case 1:
SPARC Platform (for Solaris 10):
1. 126363-03 or later (SunOS 5.10: X Window System changes - Solaris
Trusted Extensions)
2. 123611-03 or later (X11 6.6.2: Trusted Extensions patch)

Trusted Extensions)
4. 127128-11 SunOS 5.10_x86: kernel patch
For Case 2:
SPARC Platform (for Solaris 10):
1. 123611-03 or later (X11 6.6.2: Trusted Extensions patch)
