[opensuse-kernel] CONFIG_CC_STACKPROTECTOR
by richard -rw- weinberger 13 Dec '13

13 Dec '13

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] Make kernel-default obsolete kernel-ppc64
by Dinar Valeev 04 Feb '13

04 Feb '13

Hi, ppc64 flavor was replaced by kernel-default. I think now kernel-default on ppc64 should obsolete kernel-ppc64, to make upgrade from 12.2 -> Factory/12.3 smoother. Is such kind of report is enough or I should come up with a patch or file a bug? Have fun, Dinar -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] openSUSE kernel of UEFI secure boot for testing
by joeyli 31 Jan '13

31 Jan '13

Hi all, In the past of 2 weeks, I backported 5 patches for support UEFI secure boot and also sent to opensuse-kernel for every experts review: [PATCH 0/11] Backported patches to lock down functions in secure boot [1] [PATCH 0/2] Backported patches for prepare KMP kernel module sign [2] [PATCH 0/4] Backported patches for support driver firmware sign [3] [PATCH 0/7] Backported patches for support load key of module sign from db, dbx and MokList (MODSIGN) [4] [PATCH 0/19] Backported patches for support UEFI variable filesystem [5] Now, I clone a kernel-source of openSUSE 12.3 and pushed those backported patches to this branch: https://gitorious.org/~joeyli/opensuse/joeylis-kernel-source/commits/openSU… And, I also push kernel source to OBS for build out kernel RPMs: https://build.opensuse.org/project/show?project=home%3Ajoeyli%3Abranches%3A… Those kernel RPMs are for anyone want to try the backported patches on openSUSE. e.g. We can set 'secureboot_enable=1' kernel parameter to lock down some functions on non-UEFI machine, then monitor the openSUSE behavior. or We want test the kernel module sign. Thanks a lot!

Hi, Are you aiming for 3.8 or will we stick with 3.7.X? Next week I want to release Beta1 and it should have the correct code line for the kernel. If your choice is 3.8, then we should go to RC2 IMO.
