Note to the project team and external observers: this is just a review
of the written opinion itself, to make sure that it accurately
reflects the issues discussed at the review. It's not intended as a
means to reopen or reargue the case, nor does it require project team
input or approval. If you do have issues with the project, please
submit those separately (preferably as the topic of a new project for
review).

Subject: Add Wireshark 0.99.5 into Solaris
Submitted by: Bart Smaalders
File: PSARC/2007/334/opinion.ms
Date: June 13th, 2007
Committee: James D. Carlson, Kais Belgaied, Mark Carl-
son, Glenn Skinner, Gary Winiger.
Product Approval Committee:

1. Summary
This project integrates Wireshark (the current name for the
open source project better known as "ethereal") into
Solaris. Wireshark provides network packet capture and
display facilities that are, in general, substantially
better than those provided by our native snoop(1M) utility.
2. Decision & Precedence Information
This project is approved as specified in reference [1-9].
The project may be delivered in a Minor release of Solaris
via the SFW consolidation.
3. Interfaces
The project exports the following interfaces.

4. Opinion
4.1. File Format Commitment
Several ARC members asked about the supported file formats.
After discussion with the submitter, we agreed that the list
of supported formats can be volatile, but that the project
has a commitment to read old formats.
4.2. Volatile Libraries
During review, one member noted that libcrypto and GNU TLS
will require contracts. However, subsequent updates from
the project team have removed the libcrypto usage, and the
project intends to integrate via the SFW consolidation along
with GNU TLS. Based on this update, no contracts have been
presented.
4.3. Rights Profiles
One member asked about rights profiles required to make
tshark and wireshark work on Solaris. The project team
updated the materials to include rights profile entries for
these two programs in the "Network Management" profile with
the least privilege necessary (net_rawaccess).
4.4. Snoop Obsolescence
The integration of wireshark effectively makes legacy
Solaris obsolete, and turns it into a burden both for sup-
port and for future networking projects that may be required
to provide both snoop and wireshark enhancements.
Accordingly, several ARC members asked about the project
team's intended direction for snoop. After discussing this
issue with the project team, the ARC members agreed that the
resource allocation required to obsolete snoop and remove it
from the system is an issue that needs to be addressed by
management. This issue led to the advisory information
listed below.
5. Minority Opinion(s)
None.
6. Advisory Information
The ARC advises Solaris management and the Solaris PAC to
raise the priority of an effort to remove the legacy snoop
utility from Solaris and OpenSolaris. The ARC members plan
to direct and approve future projects with the assumption
that snoop removal is the intended direction, but may need
to revisit this issue (likely at substantial expense and

inconvenience to other project teams) if prompt action is
not taken.
7. Appendices
7.1. Appendix A: Technical Changes Required
None.
7.2. Appendix B: Technical Changes Advised
None.
