Subject: [PATCH] pam: add a call to pam_namespace
b11b5f
b11b5f
A call to pam_namespace is required so that children of user@.service end up in
b11b5f
a namespace as expected. pam_namespace gets called as part of the stack that
b11b5f
creates a session (login, sshd, gdm, etc.) and those processes end up in a
b11b5f
namespace, but it also needs to be called from our stack which is parallel and
b11b5f
descends from pid1 itself.
b11b5f
b11b5f
The call to pam_namespace is similar to the call to pam_keyinit that was added
b11b5f
in ab79099d1684457d040ee7c28b2012e8c1ea9a4f. The pam stack for user@.service
b11b5f
creates a new session which is disconnected from the parent environment. Both
b11b5f
calls are not suitable for inclusion in the shared part of the stack (e.g.
b11b5f
@system-auth on Fedora/RHEL systems), because for example su/sudo/runuser
b11b5f
should not include them.
