Description Arfrever Frehtes Taifersar Arahesis 2018-04-17 01:35:37 UTC
sys-apps/file-5.33 changed output for ELF files, which results in no files (either executables or libraries) being stripped.

Example showing difference ("LSB shared object" versus "LSB pie executable"):

# file --version
magic file from /usr/share/misc/magic
# file /usr/bin/wpa_cli
/usr/bin/wpa_cli: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/, for GNU/Linux 4.0.0, not stripped

# file --version
magic file from /usr/share/misc/magic
# file /usr/bin/wpa_cli
/usr/bin/wpa_cli: ELF 64-bit LSB pie executable x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/, for GNU/Linux 4.0.0, not stripped

Would be nice to mask this to give people a while to upgrade their package managers.
Comment 4 Zac Medico gentoo-dev 2018-07-02 18:51:36 UTC
Fixed in portage-2.3.40-r1.
