+++ This bug was initially created as a clone of Bug #198623 +++ This package contains the "su" program for which the PAM script needs to be modified. The "su" program also needs its PAM script duplicating so that there's a separate script for "su - [user]" mode. WHAT NEEDS TO BE DONE ===================== The PAM scripts for the login programs need to be altered to forcibly create a new session keyring when a login event occurs. These simply require the following line adding to their PAM scripts: session optional pam_keyinit.so force revoke This forces them to create a new session keyring during login, replacing the one inherited from their parent, and causes the session keyring so created to be revoked when the login process exits. Ideally, this should be "required" not "optional", but it still has to work if the pam_keyinit.so library is absent. The authlogin program needs modifying to add: session optional pam_keyinit.so revoke To the default session (system-auth). This just creates a new session keyring if one doesn't yet exist for this process. The "su" program needs to split its "su - [user]" mode PAM script from its "su [user]" PAM script, so that the former can forcibly create a keyring whilst the latter doesn't.
Created attachment 132363 [details] Patch to split su/runuser -l PAM scripts and add keyinit instructions This patch modifies the devel/ directory contents (spec file, PAM scripts and adds a code patch) to split the su/runuser -l PAM scripts from the normal su/runuser PAM scripts. It also adds keyinit instructions to those PAM scripts as needed.
Applied in CVS. Thanks.
