** Description changed:
- Despite the distribution having enabled frame pointers globally, the
- binaries shipped by libdmapsharing don't have frame pointers.
+ [ Impact ]
- It is likely due to the build system being pretty screwed up: it builds
- the library once using the CFLAGS, then rebuilds it with custom flags
- for the test suite, and we ship the latter version.
+ In order to help developers with profiling, Ubuntu enabled frame-
+ pointers for packages in the main archive.
+
+ [https://ubuntu.com/blog/ubuntu-performance-engineering-with-frame-
+ pointers-by-default](https://ubuntu.com/blog/ubuntu-performance-
+ engineering-with-frame-pointers-by-default)
+
+ The `Affects` packages were missed due to the packaging issues. These
+ have been fixed on Oracular and can now be ported to Noble.
+
+ [ Test Plan ]
+
+ Look at the DW_AT_producer in the associated debug ELF file for flags.
+ -fno-omit-frame-pointer should be present after the fix.
+
+ The following scripts can be used as a reference

+
+ -fno-omit-frame-pointer is also present in build logs and now binaries
+ are not rebuilt without this flag anymore to run tests.
+
+
+ [ Where problems could occur ]
+
+ No source changes are made. The packaging fixes have enabled other
+ security hardening flags. This could have unintended effects.
+
+ [ Other Info ]
+
+ Changes in dpkg have been made to make sure frame-pointers are not
+ enabled on s390x and ppc64el.
