netlink_kernel_create() always returns NULL
by YANG 22 Feb '11

22 Feb '11

My code fragment is below: "*nl_sk = netlink_kernel_create(16, 0, nl_data_ready, THIS_MODULE);"* It can be "make" and "insmod" correctly. But error mesage is printed into log. It indicates the netlink_kernel_create() returns NULL. Once I change the firt parameter to another(<32 && >16), system crash when I execute insmod. Is the protocol ID occupied? Why can't use another and how to define a new ID? I have tried to update net_link.h but fail also.

Just to remove any ambiguity : are you saying that the mentioned solutions would work for our given definition of the 'problem'; or that they are too cumbersome and perhaps an overkill for our simple requirements. - KB

Dearest Larry, I AM SO FUCKING SICK AND TIRED OF YOUR ENDLESS DRIVEL PASSING THROUGH MY INBOX, I may give up on this distro based on you and you ALONE. PS: Shouldn't you be busy running your business rather than running your fingers on a mailing list? PS #2: Looking at your business website, it appears your "store" is low on product. Perhaps you should concentrate on things that matter? Graciously: Ant.

Watch One, Do One, Teach One (the simple teaching method used in medical schools)
by Larry Vaden 21 Feb '11

21 Feb '11

While it is understood that it is not the responsibility of the CentOS Team to teach the community, nevertheless, it would be helpful if the CentOS Team (or others in the know) could list a handful of packages that are among the 600 Johnny reports as requiring attention in C6, preferably some that won't even compile, others that require comparison with the upstream binaries to note the problem. N.B.: . for C 3, 4 and 5, to date, we've watched nearly 4,000 (albeit it was hard to see anything other than the outcome, which was GREAT) . many of us are ready and would like to do one, so please tell us which packages in the corpus will result in a failure in a stock/vanilla build environment. . perhaps somewhere between C6 and C7 some will pass muster. THANKS for your consideration of the use of this widely used method of teaching MDs, DVMs, DDSs, et al. kind regards/ldv/vaden(a)texoma.net

php-5.2.x needs adopting
by Karanbir Singh 21 Feb '11

21 Feb '11

hi guys, We've had a php-5.2 in c5-testing which was based on the rhwas sources from upstream. Quite a few people have that package in production at various places however, this looks mostly unsupported upstream now. Would someone like to adopt the 5.2 packages, bring them upto 5.2.17 and maintain it going forward for c5 ? Regards, - KB

a little levity and a URL for a PhD thesis about Trusting Trust
by Larry Vaden 21 Feb '11

21 Feb '11

While learning from rpm and yum guru Jeff Johnson offlist, the thought occurred that some might enjoy reading <http://www.dwheeler.com/fourfours/> and Dr. Wheeler's thesis entitled "Fully Countering Trusting Trust through Diverse Double-Compiling" at <http://www.dwheeler.com/trusting-trust/dissertation/html/wheeler-trusting-t…>. Enjoy!

Can I do computation with giant integer in kernel?
by YANG 21 Feb '11

21 Feb '11

I need compute some **polynomials using giant integer with power of numbers perhaps. I found GMP library can do this in user mode. How about in kernel? Is there any existing codes? Or, I should keep the computation in user mode and use netlink to let kernel pass the task to application for computing and wait for result asynchronously. But I worry about efficience by using this method. Does it cause mode switch frequently, even on multi-core cpu chip?

Ja oder nein: is cygwin-setup process a viable alternative to present day builds?
by Larry Vaden 19 Feb '11

19 Feb '11

This question keys off IIRC Johnny's remarks earlier in the day about how much work it is to build a release. This question is addressed to those build gurus on this list who have forgotten more about the build process than this poster will ever know and further have first hand knowledge|experience with cygwin-setup. Because 4 of our servers are Windows boxen running IIS (to enable small business folks to build web sites with Front Page), considerable fondness for the cygwin build process has developed to the extent that Windows commands via CLI and GUI are hardly ever done. At the end of the day, other than RPM package management, what are the substantial differences that would preclude a cygwin-setup-like build process from being used to build and maintain the release and would it be a lot faster and less labor intensive? kind regards/ldv/vaden(a)texoma.net

Re: [CentOS-devel] [CentOS] Any update on 5.6 / 6?

I would certainly like to help with CentOS and previously looked after a number of packages for cAos. I appreciate that now isn't a good time as you are all very busy and I'm currently moving house so I won't be much immediate help. Take care, Ben

php53 / bind97
by Karanbir Singh 03 Feb '11

03 Feb '11

hi, php53 and bind97 from the 5.6/ tree are available in the c5-testing repo, so test away. Consider the pkgs as mostly production ready, but features that rely on other new pkgs or updates in 5.6 may not work. If you run into one, let us know either on the list here, or in #centos-devel on irc.freenode.net - KB
