Cross-compilation of dist/Storable fails #16646
Comments
From [email protected]I’m the package maintainer for Perl on OpenWrt. We’re trying to ship 5.28.0 since 5.26.2 and below have the Archive::Tar CVE-2018-12015. Unfortunately, dist/Storable/stacksize is not a cross-compilation friendly script, since it assumes that one is never cross-compiling. Clearly that’s not the case. The bug manifests as: cd dist/Storable ; LD_LIBRARY_PATH=/home/philipp/lede/build_dir/target-x86_64_musl/perl/perl-5.28.0 make lib/Storable/Limit.pm And it’s exactly because we are cross-compiling that we build and use miniperl, as well as setting: usecrosscompile=‘define’ in config.sh. We’ve been calling out this issue for almost a month now, and it’s the sole blocker to updating our distro's migration to 5.28.0 and hence mitigating the CVE. This is urgent. Thanks ======== Platform: Characteristics of this binary (from libperl): |

Seems to be working! Thanks. Had to tweak it slight to get it to work with 5.28.0 and not “blead/master”: |
