Deep within the ubiqx binary tree modules there is a function called ubi_trTraverse(). This function was originally intended to make it easy to traverse the contents of a binary tree (including AVL and Splay trees), and perform some operation on the contents of each entry.

This function has been a thorn for a while, because programmers insisted on trying to use ubi_trTraverse() to selectively remove nodes from the tree—a trick that the function was not designed to perform.

Bad.

So, there's a new version of the ubi_BinTree module that contains a small fix. The ubi_trTraverse() function now finds the next node in the tree before calling the user-supplied function (the *EveryNode parameter).

With this update, it is now safe to remove nodes from the tree during a traversal using the ubi_trTraverse() function.

You can find the updated ubi_BinTree module in the src/ directory, or download the whole library from the pub/ directory.

New ubi_BinTree version number: 4.13

We always like to see new reviews of Implementing CIFS.

[The Book]

[August 20th, 2005]
It has been pathetcially too long since the last update. Sorry.

There's a review of Implementing CIFS, posted last March, available at TaoSecurity.
Be sure to read the comments below the review!

What else...

  • Crh has a new job that involves a lot of fiddling with CIFS, NFS, and iSCSI. Mostly iSCSI. This is an interesting protocol, lots of fun digging into it.
  • Annotations are slowly being added to the online version of Implementing CIFS.

Nice plug for Implementing CIFS in this Network World Fusion article. Vance caught sight of it in the Australian edition of Linux World as well.

[October 1st, 2004]
jCIFS v1.1.0 is now available.

[June 10th, 2004]
I stumbled across a new review of Implementing CIFS. It appeared in the May, 2004 edition of the IEEE Network New Books and Multimedia column.

[June 6th, 2004]
There's a function in the ubiqx binary tree module that searches for a leaf node in the tree. That function has been rewritten so that it looks deeper into the tree to find an available leaf node, thus improving the behavior of the ubi_Cache module.

Previously, there were rare cases in which a recently added cache entry might be removed from the cache--the opposite of what'd you'd want to have happen. The new code does a little more work to find a longer path through the tree, and thus an older cache entry.

Download the latest revision of the ubiqx library.

Overall, the ubiqx modules have been very stable over the past many years. This one small problem has been hanging over my head for a while (ever since Simo discovered it). I'm glad to have it finally resolved. -- crh

Whoo Hoo!
A Slashdot Review!
(...and a good one, too!)

Yes, the online version was wholloped by slashdotters. I can't wait to see the spike in the statistics. I hope folks will bookmark the site and come back later!

Ooooh! I like this review, which compliments my "technical vigor".
... someone get a bucket of ice water so I can soak my ego.   :-)

Some wonderful reviews of Implementing CIFS have been posted on Amazon.

Thanks, Tridge!
Thanks, Rafeeq!

There is an Interview with crh on searchEnterpriseLinux, and a bit of commentary on NewsForge.

[August 26, 2003]
Implementing CIFS, the book that took me 3.5 years to write, is now absolutely available in bookstores and online. I ordered a copy online and received it today, August 26th. Hurray!   :-)

Just back from an intense week at the 2003 SNIA CIFS Conference and Plugfest in San Jose. The Samba Team provided the entertainment (and the tutorials). Thanks to all of the corporate sponsors for making it happen!

Oh... and Microsoft decided, once again, not to show up. Funny. It's their protocol suite.

[July, 2003]
·  jCIFS v0.7.11 is available.
·  Eric Glass has joined the jCIFS Team, and has been working on NTLM authentication over HTTP. His work has helped to expand the understanding of CIFS authentication mechanisms in the CIFS community.
·  Version 05 of the SMB URL Internet Draft has been posted by the IETF.

[April, 2003]
Crh gave a half-hour introductory talk on CIFS authentication mechanisms at Samba Experience 2003.

Slides and audio for most of the talks are on-line.

[September 4, 2002]
The CIFS conference ended almost two weeks ago and I'm still digging out. I gave a tutorial, and took a lot of notes during the sessions and break-outs. Curiously, Microsoft didn't show up this year. Strange, as I have heard that the week before they were at LinuxWorld with a big banner reading "Interoperability". Hmmm...

[Samba Team photo 2002] There were 15 Samba Team folk at the conference!

[May 2, 2002]
Just got back from the Samba eXPerience conference in Göttingen, Germany. A wonderful time was had by all. We hope to post a few pictures when they are available.

Also spent some time at Telco Tech. They gave us a MicroLISS Home/Small Office Firewall and VPN box for testing. This is a new product, which we helped to design. Features include:

  • VPN end-point
  • Firewall
  • Intrusion Detection
  • Routing
  • Network Address and Port Translation
  • PPPoE
  • Caching DNS Server
  • DHCP Server
  • Web-Based (HTTPS) Administration
