** Description changed: [Impact] 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 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 https://gist.github.com/julian-klode/85e55553f85c410a1b856a93dce77208 https://gist.github.com/julian-klode/95818246eaef0ac6a54588f7f368e25c Run the smoke test: $apt-get install libio-dirent-perl - $cat << EOF > test.pl - use IO::Dirent; - - ## slurp-style - opendir DIR, "/etc"; - my @entries = readdirent(DIR); - closedir DIR; - - print \$entries[0]->{name}, "\n"; - print \$entries[0]->{type}, "\n"; - print \$entries[0]->{inode}, "\n"; - - ## using the enumerator - opendir DIR, "/etc"; - while( my \$entry = nextdirent(DIR) ) { - print \$entry->{name} . "\n"; - print \$entry->{type} . "\n"; - print \$entry->{inode} . "\n"; - } - closedir DIR; - EOF - $perl test.pl + $apt source libio-dirent-perl + cd to package source directory + $perl test.pl - The test should print contents of /etc/ directory [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. [Original Description] Note: libio-dirent-perl has very old packaging that has not been updated for a while. The package can be switched to a modern debhelper version and this will allow to make it honour dpkg build flags.
