Public bug reported: SRU Justification
Impact: Our kernel packaging currently has support for backporting kernels to older releases. This includes appending ~BACKPORT_SUFFIX to the version string for the backport kernel, where BACKPORT_SUFFIX is defined in update.conf. We need to start doing similar forward ported kernels, but BACKPORT_SUFFIX should be appended using a + rather than a ~. Our kernel packaging cannot easily determine whether a + or a ~ is appropriate. Fix: Move the leading character into BACKPORT_SUFFIX, and do not insert any leading characters from the kernel packaging scripts. Since the script which generates update.conf has access to information from kernel-series, it can more easily determine whether + or ~ is the appropriate leader. Test Case: Run through the normal steps for updating a backport kernel. The version string generated should have ~SERIES for a backport to an older series, and +SERIES for a backport to a newer series. Regression Potential: Backport kernels could end up with an incorrect version strings. Since all kernel uploads undergo review, any such errors should be caught before uploading. ** Affects: linux (Ubuntu) Importance: Medium Assignee: Seth Forshee (sforshee) Status: In Progress ** Affects: linux (Ubuntu Precise) Importance: Undecided Status: New ** Affects: linux (Ubuntu Trusty) Importance: Undecided Status: New ** Affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux (Ubuntu Groovy) Importance: Undecided Status: New ** Affects: linux (Ubuntu Hirsute) Importance: Medium Assignee: Seth Forshee (sforshee) Status: In Progress ** Also affects: linux (Ubuntu Hirsute) Importance: Medium Assignee: Seth Forshee (sforshee) Status: In Progress ** Also affects: linux (Ubuntu Trusty) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Groovy) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Precise) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1902957 Title: Update kernel packaging to support forward porting kernels Status in linux package in Ubuntu: In Progress Status in linux source package in Precise: New Status in linux source package in Trusty: New Status in linux source package in Xenial: New Status in linux source package in Bionic: New Status in linux source package in Focal: New Status in linux source package in Groovy: New Status in linux source package in Hirsute: In Progress Bug description: SRU Justification Impact: Our kernel packaging currently has support for backporting kernels to older releases.
