** Description changed: + + FeatureFreeze Exception (FFE): + ============================== + + Reason, rationale and benefits: + ------------------------------- + + The feature is based on the combination of two tickets: + - 1783088 + this ticket for the kernel part was just created for completeness reasons + this part of the functionality automatically came with kernel 4.17 + hence this LP ticket is 'Fix Released' + - 1783086 + this is the 'user space' part of the functionality that should be addressed by the FFE + There was a little confusion if this belongs to the FeatureFreeze or KernelFreeze. + Since it's a package maintained by the kernel team the misconception came up that it is not affected by the Feature, but by the Kernel Freeze, + hence it was not processed in time and information was missing. + + Without this patch the (new) "--kexec-file-syscall" option for s390x cannot be used with cosmic. + And the customer/partner needs to wait for the next d* release (means for several month). + + This FFE now asks if the single commit (below) can be added to the + kexec-tools (Ubuntu) of cosmic: + + Description: + ------------ + + commit d4a948c268272cf37c71be820fb02bf40e56292b + Author: Philipp Rudo <pr...@linux.ibm.com> + Date: Wed May 16 14:27:18 2018 +0200 + + kexec/s390: Add support for kexec_file_load + Since kernel 4.17-rc2 s390 supports the kexec_file_load system call. + Add the new system call to kexec-tools and provide the -s (--kexec-file-syscall) option for s390 to support this new feature. + + Impact / Risk: + -------------- + + Since the function / option is new and for s390(x) the risk is pretty low. + There are no APIs expected to break or existing functions that are expected to fail while introducing this. + Package dependencies will not change, nor the install/upgrade behaviour after this got added. + + Testing of the code, test builds and verification was already done by IBM. + (see comment # 4) + + _________________________ + + Provide a capability to load signed kernels. I.e. to boot signed kernels - - from a Linux based boot loader or initial boot image + - from a Linux based boot loader or initial boot image - as required for secure/trusted boot mechanisms - for kdump kernels Function consist of 2 contributions - kernel 4.17 (available) - kexec-tools (currently not available)
