description |
Bug #1954676 (https://bugs.launchpad.net/bugs/1954676) was opened because of kernel soft lockup issues with Jammy 5.15. A temporary patch to gcc-11 was identified and released under debian/patches/gcc-ibmz-plt-revert.diff, which reverted gcc commit 0990d93 ("IBM Z: Use @PLT symbols for local functions in 64-bit mode"). An eventual fix to the kernel lockup was released under the upstream Linux kernel, commit f3b7e73b2c66.
To this end, the debian/patches/gcc-ibmz-plt-revert.diff patch should be removed from gcc-11 as it presents issues with object file symbols. An attempt at this is in my PPA - https://launchpad.net/~john-cabaj/+archive/ubuntu/gcc-11). This allowed me to get past my issues with the object file symbols. |
[ Impact ]
* Bug #1954676 (https://bugs.launchpad.net/bugs/1954676) was opened because of kernel soft lockup issues with Jammy 5.15. A temporary patch to gcc-11 was identified and released under debian/patches/gcc-ibmz-plt-revert.diff, which reverted gcc commit 0990d93 ("IBM Z: Use @PLT symbols for local functions in 64-bit mode"). An eventual fix to the kernel lockup was released under the upstream Linux kernel, commit f3b7e73b2c66.
* To this end, the debian/patches/gcc-ibmz-plt-revert.diff patch should be removed from gcc-11 as it presents issues with object file symbols. An attempt at this is in my PPA - https://launchpad.net/~john-cabaj/+archive/ubuntu/gcc-11). This allowed me to get past my issues with the object file symbols.
[ Test Plan ]
* use kpatch-build testcases to build and load a livepatch on s390x kernel built with gcc-11
* it should be successful
[ Where problems could occur ]
* Whilst the kernel issues was worked-around by reverting compiler changes, the actual issue was in the kernel code; which has since been fixed. In ubuntu the kernel has been fixed since Ubuntu-5.15.0-20.20
[ Other Info ]
* A bit sad that this was not detected earlier, and compiler fixed up earlier. |
