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 + 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.

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! :-) ## History |
