SUNBUG 6837313

Date of Resolved Release: 13-Jul-2010

Description

An issue with the UltraSPARC T2 random number generator device driver n2rng(7d) as delivered in Solaris 10 Kernel Patch 127127-11 and certain OpenSolaris builds may cause random memory corruption on UltraSPARC T2 systems, resulting in hard to diagnose panics.

Likelihood of Occurrence

This issue can occur in the following releases:

SPARC Platform

•Solaris 10 with patch 127127-11 and without patch 140151-02

•OpenSolaris based upon builds snv_80 through snv_118

Notes

1. OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. The base build can be derived as follows:

$ uname -vsnv_1122. Solaris 8 and 9 are not impacted by this issue. Solaris 10 and OpenSolaris on the x86 platform are not impacted by this issue

3. This issue only affects the UltraSPARC T2 family of systems. Systems in the affected UltraSPARC T2 family are the following:

T5120/T5220, T5140/T5240, T5440, T6320, T6340, CP3260

4. This issue only occurs when security oriented applications use the n2rng(7d) driver to generate random numbers/data. Applications which utilize underlying network security protocols such as SSL(3) or IPsec(7P) indirectly use the n2rng driver.

Possible Symptoms

There are no predictable symptoms that would indicate the described issue has occurred.

Workaround or Resolution

This issue is addressed in the following releases:

SPARC Platform

•Solaris 10 with patch 140151-02 or later

•OpenSolaris based upon builds snv_119 or later
