-The GNU Hurd project has been accepted as a mentoring organization for
+The GNU Hurd project has successfully participated in
 the [Google Summer of Code
 2008](http://code.google.com/soc/2008/hurd/about.html)!
 
-Student selection is over, and we have four slots -- quite some more than the
-one we had the previous years under the GNU umbrella... Let's hope for some
-good results :-)
+All in all we had five students working on a diverse selection of five projects
+from our [[ideas_list|gsoc/project_ideas]]. All of the projects were more or
+less successful:
 
-The selected projects are:
+## Projects
 
-* Lisp binding for Hurd translator libraries
-* Network virtualization for subhurds etc.
-* Usable procfs implementation
-* dtrace support
+* [[Sergiu_Ivanov|scolobb]] worked on namespace-based translator selection.
+  Although he wasn't an official (sponsored) GSoC student, he worked on his
+  project quite as steady as the other students (except for a two week
+  vacation). The project however was hampered by various misunderstandings,
+  wrong assumptions, and several major redesigns during the course of the work
+  -- which is probably more our fault than the student's. In the end, he was
+  able to complete nsmux (the main namespace proxy handling the magic filename
+  lookups, running dynamic translators on demand); however, he still works on
+  finishing the translator stack filtering, necessary to implement some of the
+  desired functionality (accessing files while skipping existing translators).
 
-Special cheers go to Sergiu Ivanov, whom we unfortunately couldn't select
-because he was impeded during the application phase, but who nevertheless is
-working on his project (namespace-based translator selection) as a volunteer
-with a dedication matching that of the selected students!
+* [[Zheng_Da|da]] worked on network virtualization and some related topics. In
+  spite of many open design question in the beginning, he did a lot of good
+  work -- finishing not only the ethernet multiplexer and filter translators,
+  which form the core of his project, but also a glibc patch to allow
+  overriding the standard socket servers with environment variables; the
+  devnode translator and a pfinet patch to allow accesing network devices
+  through device files; support for setting the network device in promiscuous
+  mode in gnumach; a pfinet patch to use BPF for the packet filtering instead
+  of the old Mach packet filters, and also to set a proper filter rule that
+  really only passes the required packages to pfinet; a patch for the subhurd
+  boot program to allow giving arbitrary virtual devices to the subhurd; and a
+  proxy for the proc server, which allows running unmodified programs with a
+  pseudo device master port instead of the real one -- providing some of the
+  subhurd functionality without having to start a complete new system instance.
+  He is still working on fixing some remaining issues, and on allowing subhurds
+  to be run by normal users.
 
-The summer session has started by the end of May, and all the students are
-making good progress. We are in good hopes of seeing five successful projects
-at the end of this summer :-)
+* [[Flavio_Cruz|flavioc]] was working on Lisp bindings for the Hurd interfaces,
+  and did a great job: Not only he implemented bindings for all low-level
+  interfaces as well as higher-level libraries for easy creation of translators
+  and other hurdish programs, but also implemented a whole bunch of sample
+  translators based on these bindings, some of them quite useful on their own
+  account. He also fixed a few bugs in the Hurd he found along the way.
+  Presently he is doing some further improvements, like additional abstractions
+  and more sample translators.
 
-## '08 SoC students and interested non-students
+* [Andrei Barbu](http://csclub.uwaterloo.ca/~abarbu/hurd/) was working on
+  porting a kernel instrumentation framework like dtrace or SystemTap. He
+  implemented the necessary kernel infrastructure (and some nice general
+  improvements along the way), making it possible to create tracing programs by
+  hand; however, only at the end of the summer he realized that SystemTap is
+  really extremely Linux-specific (while dtrace was ruled out already at the
+  setout because of licensing problems), so there is no nice frontend yet.
+  Unfortunately he was not able to continue work beyond the official deadline
+  because of his PhD.
 
-Minutes from the IRC meetings: [[25April08Minutes]], [[02May08Minutes]], [[16May08Minutes]]
+* [[Madhusudan.C.S|procfs]] was working on a new procfs implementation, to
+  allow runnig existing programs based on Linux procfs out of the box. He
+  managed to implement all the necessary information bits, so the most
+  important procfs programs now work; and also fixed the procps program suite
+  to actually build on the Hurd. There are still some major bugs left, though.
+  Aside from fixing the remaining bugs, he now works on adding some more
+  information bits that are nontrivial to implement, and on fixing libgtop to
+  work for us as well.
 
-## Wiki pages kept by '08 SoC students and interested non-students
+## IRC meetings
 
-  * [[scolobb]] - Namespace-based translator selection
-  * [[da]] - Network virtualization
-  * [[flavioc]] - Lisp bindings
-  * [andrei](http://csclub.uwaterloo.ca/~abarbu/hurd/) - dtrace/systemtap port
-  * [[procfs]] - GNU/Linux compatible procfs pseudo filesystem
+Since the selection of the students on we have had regular GSoC IRC meetings,
+every Friday 19:00 UTC.
+
+Minutes from some of the meetings: [[25April08Minutes]], [[02May08Minutes]], [[16May08Minutes]]
+
+We decided to keep up the meetings after the end of official GSoC, so things
+can be properly wrapped up for upstream submission; but also because the
+students want to continue discussing progress with their ongoing work,
+problems, future directions etc.
+
+I also think that regular IRC meetings are a good thing in general.
+
+As always, the meetings are not only for (former) GSoC students and mentors,
+but open to any interested party :-)
+
+If someone of you is lurking around here and would like to contribute,
+but feel that you could do so better under formal mentoring: Please
+speak up at the meeting! :-)
