Description Steve Moyes 2025-03-03 12:34:53 UTC

Emerge --info is here https://pastebin.com/Pjk65s6h

/lib64/security/pam_userdb.so is not built with sys-libs/pam-1.7.0_p20241230-r3 nolonger supports this file (berkdb use flag enabled). Downgrading to sys-libs/pam-1.6.1 recreates the file.

This was discovered when logging into vsftpd with virtual users configured.

Thanks for filing this.

Context/background is https://forums.gentoo.org/viewtopic-t-1173166.html.

For future, please include emerge --info and such as attachments rather than a pastebin as they expire/may not be accessible behind a firewall.

Having a look...

Could you run: `ebuild /var/db/repos/gentoo/sys-libs/pam/pam-1.7.0_p20241230-r3.ebuild clean configure`, and upload the build.log from /var/tmp/portage/sys-libs/pam-*/temp/build.log and meson-log.txt in the builddir too?

It looks like we pass -Ddb-uniquename=5.3 to meson setup. meson attempts to link against -ldb5.3 (libdb5.3.so).

sys-libs/db:5.3 installs libdb-5.3.so, not libdb5.3.so.

I believe we could fix this by passing -Ddb-uniquename=-5.3 to meson setup instead.

pam_userdb.so is now created.  I'll dig into vsftpd and raise another bug if required.  Thanks again for the assist and blistering speed.
