from the GPL-FTW dept.

Mark J. Wielaard has written a brief blog post about a crucial license change for the dtrace performance analysis and troubleshooting tool. It has been available for most other systems, notably Solaris derivatives, FreeBSD, and OS X, but not for Linux. That may change soon, or at least have the possibility to change.

At Fosdem we had a talk on dtrace for linux in the Debugging Tools devroom.

Not explicitly mentioned in that talk, but certainly the most exciting thing, is that Oracle is doing a proper linux kernel port:

dtrace: Integrate DTrace Modules into kernel proper

This changeset integrates DTrace module sources into the main kernel source tree under the GPLv2 license. Sources have been moved to appropriate locations in the kernel tree.

That is right, dtrace dropped the CDDL and switched to the GPL!

This change improves the utility of dtrace and gives a badly needed boost to Oracle's image. So will the license for ZFS be corrected next?

Source : dtrace for linux; Oracle does the right thing.
