dtrace for Linux; Oracle Does the Right Thing

Mark J. Wielaard has written a brief blog post about a crucial license change for the dtrace [dtrace.org] 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 [fosdem.org] in the Debugging Tools devroom [fosdem.org].

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

commit e1744f50ee9bc1978d41db7cc93bcf30687853e6 [oracle.com] Author: Tomas Jedlicka <tomas.jedlicka@oracle.com> Date: Tue Aug 1 09:15:44 2017 -0400 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?
