https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258384 Bug ID: 258384 Summary: pam_ssh.so.6 reporting undefined symbol Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: madpilot@FreeBSD.org Hi, I am trying to update my system to latest head (commit 4ccbbe5f0689513de4399d6dad43e85d97ad9cde) and upon updating the system I'm seeing a new issue. I use pam_ssh when logging in via display manager (lightdm) to login using the ssh key phrase and automatically load the ssh key: (from /etc/pam.d/xdm, included by light pam.d file) auth sufficient pam_ssh.so no_warn try_first_pass auth required pam_unix.so no_warn try_first_pass After updating I get this error: Sep 9 10:27:56 tommy lightdm: in try_dlopen(): /usr/lib/pam_ssh.so.6: /usr/lib/libprivatessh.so.5: Undefined symbol "sshsk_sign" Sep 9 10:27:56 tommy lightdm: in openpam_load_module(): no pam_ssh.so found Looks like pam_ssh is somehow trying to call a function not available, due to our openssh being compiled without U2F support. I noticed that some ifdefs where added  and then removed  upstream. I tried adding back the ifdefs in  but it is not making any difference. Unluckily I don't know how this actually works in code and am failing to identify the code path which is causing pam_ssh to call the undefined function. (still trying) In the while I thought I'd report the issue. If any further info is necessary please ask.  https://github.com/openssh/openssh-portable/commit/1e0b248d47c96be944868a735553af8482300a07  https://github.com/openssh/openssh-portable/commit/9244990ecdcfa36bb9371058111685b05f201c1e -- You are receiving this mail because: You are the assignee for the bug.
