Introduction
Hello everybody, My name is David Forsythe and I'll be working on allowing parallel builds in the ports collection for Summer of Code this year. I'm a second year student at the University of Maryland, College Park studying computer science. I'm extremely excited to work on this project over the summer and I hope my work is beneficial to the FreeBSD community. I was already planning on devoting a bunch of my free time this summer to working on this type of thing, so an @freebsd.org alias, a t-shirt, and a bit of cash are just icing on the cake (no seriously, getting a FreeBSD mail alias excited me so much I'm a little bit embarrassed...) I hope that my project turns out well and I can continue to work with the FreeBSD development community far into the future. Working with you guys is really a dream come true!

Re: devctl (alike?) for devfs
I decided to do it in devfs_devs.c because there are less entry points
there and the code is much simpler (you know: aliases, clones).
I also had to add !cold condition, because apparently we have devices
created so early in the boot, that devctl is not ready to handle a
notification. My system hanged after only getting to the following line
in verbose boot:
ULE: setup cpu 0
However it is possible that it did something wrong - at that time I had
devctl calls in kern_conf.
I guess this also should be OK from the user perspective because they
would be interested in device events after a system is booted and devd
is running.
Here is a log of devd started with -dD flags in single-user mode, then I
attached and later detached an external hdd:

My GSoC Intro...
Hello everybody!!! My name is Przemek Witaszczyk and I am one of those very happy FreeBSD GSoCers of 2008:) I am 25 years old and I come from Polad. Currently I'm working on my PhD in the field of theoretical physics (AdS/CFT correspondence, one nifty thing that came out from the superstrings theory...). MSc also in theory, two years ago at Jagiellonian University, Krakow... My story of open source operating systems began in high school, when I met Linux and was persuaded by the fact that you can never stop configuring them:>. Since then I've checked out several OSes such like Solaris, Tru64 and even Plan9, but no doubt FreeBSD was the one I'd liked the most. So here I am. Partially by an accident I began working with embedded systems developer, Rafal Jaworowski (and his UltraTeam:>), who asked me if I'd liked to take a try in GSoC. So eventually we did it and now with him as my Mentor I'm going to port FreeBSD to Efika - a PPC based system on a chip eval board. What I expect the most is learning as much as possible about the unix kernel and getting to know with as many fbsd developers as possible. And - to succeed, of course.. Greets!

MK_SSP used for both libssp and -fstack-protector
Hi all, Another problem I have is that MK_SSP is used for both libssp and -fstack-protector. This could be a problem. I think moving libssp under MK_GNU_SUPPORT would make sense, but this would break backward compatibility WRT RELENG_7. What to do about this? FYI, libssp is not used at all currently since the few symbols required by SSP are provided in libc. The only use I can figure is when you want to link a program without libc while still protecting it with SSP. Thank you for your help.

Using special CFLAGS for a single file without writing the rule
Hi Ruslan, hi all,
I don't know if you followed the thread on -arch@, but the outcome is
basically that SSP should be disabled for a couple of files:
lib/csu/*
gnu/lib/csu/* (reported by antoine@, but I couldn't verify this one)
lib/libc/sys/stack_protector.c
sys/kern/stack_protector.c
Antoine Brodin supplied a patch for the kernel part:
+kern/stack_protector.c standard\
+ compile-with"${NORMAL_C:N-fstack-protector*}"
As for lib/csu/*, this is straightforward, I just have to set
WITHOUT_SSP in the Makefile.
The hardest one is lib/libc/sys/stack_protector.c. I endeavored to find
a way to compile a single file with ${CFLAGS:N-fstack-protector*}, but I
found no recipe but writing the whole rule for this file. I would
really like to avoid this solution so as to not override bsd.lib.mk
settings.
Considering your big experience with the build infrastructure, I suspect
you would have a solution.
Thank you for your help.
Regards,
--

Re: Please welcome our Summer of Code Students
Hi everyone I'm Nick Barkas, and will be working on making memory usage for dirhash dynamic. I'm a master's student studying scientific computing at Kungliga Tekniska högskolan (Royal Institute of Technology) in Stockholm. I have been using FreeBSD for several years and I am very happy to get this chance to spend a lot of time hacking on it, learning more about what goes on in the kernel, and hopefully making UFS2 faster. I also work for a game company called Three Rings Design based in San Francisco. We use FreeBSD for most of our servers there, and I do backend software engineering and system administration. Thanks!
