Hi! I'm wondering why CONFIG_CC_STACKPROTECTOR is disabled on openSUSE. Debian and Fedora seem to enabled it per default. What's the deal? -- Thanks, //richard -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] How to compile the kernel style "OpenSuSE"?
by João Silva 03 Sep '12

03 Sep '12

Hello, I have a doubt in the correct procedure for compiling the operating system kernel in OpenSUSE. I have sought help in forums, but nobody could help me, so I'm turning to you. I hope you can understand me, my English is not very good. I'm using version 12.1 of the "OpenSUSE" with kernel "1.3.10-1.16-default." After downloading the kernel source code and all the build dependencies via "YAST", run the following commands as "root": cd /usr/src/linux-3.1.10-1.16/; make clean; make mrproper; cp /boot/config-3.1.10-1.16-default ./.config; make menuconfig; At this stage I would not change any configuration of the kernel, just select the file ".config" and choose a name for the kernel that will be compiled. After these procedures, I save and start the build process via the command: make dep; make rpm; After waiting for the build is done, I checked the package ".rpm" generated has a size of 317 MB, and the repository of the "OpenSUSE", the size of this file is approximately 37 MB. After installing the kernel compiled, I noticed no difference in the number of generated binary files, only in their size. So, I wonder, because the kernel is compiled much mair than the kernel provided by the repository "OpenSUSE"?, And I'm using the same configuration. And what is the correct way to compile the kernel in OpenSUSE?. So I can generate a size compatible with the repository. Thank you for the information, João -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

Hi, The patch below removes some optional parts from the config that makes it build again with the 3.6.rc3. I'm currently burn-in testing this kernel, so far it looks good. Please apply. Thanks, Dirk

[opensuse-kernel] Tumbleweed kernel changes to help upstream development
by Greg KH 29 Aug '12

29 Aug '12

Hi all, As part of one of the Linux kernel Summit discussions today, it was brought up that after a kernel is released (for example 3.5), it's a bit too late to be doing testing to see how well it is working out. The .0 release is usually a bit rough, and it takes until the .1 or .2 release to get most major issues out of the way. So, the kernel developers would like to get a wider range of testing, and one thing proposed would be to have rolling distros switch their kernel over a bit earlier to the new release than they had been doing. Specifically, around the -rc5 point in time would be great. That way, any reported regressions could be fixed sooner and get into the final .0 release for everyone to use. Now this does place a bit of a larger burden on the users of those distros to be diligent in reporting problems, and the distro engineers to report the issues upstream as well, but it sounds like a reasonable thing to try out. So, for the next kernel release, I'm thinking of switching the kernel in Tumbleweed over to 3.6 at the -rc5 timeframe. Does anyone strongly object to this happening? thanks, greg k-h -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org
