Bruce, Yocto kernel folks: Here is the next 5.2.x stable update "extension" primarily created for the Yocto project, as the next v5.2.x post-EOL release.
This maintenance is most likely to wind down in September, so folks should plan their own maintenance or migration path off of this v5.2.x update stream in advance of that. The content is from an audit of what went into the v5.4.42 to v5.4.44 releases - plus any upstream commits listed as Fixes: for backports in the above v5.4.x content, and a few upstream commits for recent CVE. There are 360 commits deployed here that were applicable for this v5.2.44 release. Probably most noticeable in that list is the gcc-10 fixes. Most of them are dealing with new warnings, and in that theme, Linus finally got sick of used-but-not-initialized false positives and disabled them by default (mainline 78a5255ffb6) so people may notice fewer warnings than before, depending on their compiler version. I did confirm that gcc-10 caused the stack canary boot fail on v5.2.43 and that the backport of a9a3ed1eff36 used here resolves that and allows a sanity boot test on this v5.2.44 to pass with gcc-10. However, I would strongly recommend that people do their own more rigorous testing before deciding to switch compiler versions, should they wish to do so. I've put this 5.2.44 queue through my normal testing, with build tests on x86-64/32, ARM-64/32, PPC and MIPS, plus some static analysis and finally some sanity runtime tests on x86-64 (raw + qemu/KVM). Please find tag v5.2.44 (4bc9d81a77e458a4c4138131e5c8da03d328a647) as the current head of linux-5.2.y branch in the repo in the kernel.org directory here: https://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux-5.2.y.git/?h=linux-5.2.y git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux-5.2.y.git for merge to standard/base in linux-yocto-5.2 and then out from there into the other base and BSP branches. For those who are interested, the evolution of the commits is here: https://git.kernel.org/cgit/linux/kernel/git/paulg/longterm-queue-5.2.git/ This repo isn't needed for anything; it just exists for transparency and so people can see the evolution of the raw commits that were originally selected to create this 5.2.x release. Paul.
