Case: 2009/381
Name: Support off-line files on SAM-QFS for Samba in Solaris
Submitter: Jiri Sasek
Owner: Daniel Hain
Status: waiting need vote 07/13/2009
Exposure: open
SUMMARY
=======
Samba is CIFS volume and printing server.
The current version of Samba (3.0.34) integrated in Solaris
does not support off-line file attribute for files stored on
a SAM-FS volume when located on an off-line storage (a tape).
Such situation has the following consequences on MS Windows
clients:
- Client's attempt to access an off-line file will fail on
timeout which is set too short to access a file stored
on a tape or any other external (off-line) storage.
- If MS Windows Explorer's current directory is set to
a directory full of off-lined files it causes a "storm"
of the tape changer arms when thumbnails are being generated.
The solution is to let Samba use libsam.so library, [4], which
provides the off-line information for files stored on a
off-line storage (a tape). Since this library is optional
on Solaris then it is necessary to use lazy binding option for
linking this library with Samba. The lazy binding option makes
sure that "smbd" (Samba daemon) will run even if libsamfs.so is
not present on the system.
When "samfs share = yes" configuration option is set in smb.conf
(Samba configuration file) and libsamfs.so is not present on the
system then calling the lazy linked library-call will not complete
the dlopen(2) call successfully and the standard message from the
run-time linker notifying about is redirected from the stderr
output to the "smbd" log file appropriate to the CIFS session
serviced by this "smbd" daemon. Samba log files can be configured
as described in smb.conf(4). In the standard distribution such log
file is located on the "/var/samba/log/log.<hostname|IP>" path.
SAM-FS library libsamfs.so is delivered by optional packages
SUNWsamfsr SUNWsamfsu and should be installed from the external
source.

Case: 2009/410
Name: Datalink Administration from Non-Global Zones
Submitter: Sebastien Roy
Owner: Sebastien Roy
Status: submitted
Exposure: open
SUMMARY
=======
Datalink Administration from Non-Global Zones
ISSUES
======
kb-01 /dev/dld included in /dev of which zones? shared or exclusive?
kb-02 Note for the opinion: I think it is useful to make stress the fact
that the scope of this case is the read/only operation (listing,
getting properties) of the subset of datalinks alowed visibility by
the global zone administrator. Any delegation of control beyond
that
will be defined on a per datalink type, in future cases.
kb-03 The case soemhow extends the meaning of the zonecfg
ip-type=exclusive
to uses of datalinks beyond and even in absence of IP instances.
One wouldn't need to plumb an interface in order to
use the datalink from the zone (through bpf or RDS sockets).
THE NEXT STEP
=============
opinion to include recommendation for improvement on link classification
nomenclature and RFE
