May need to add a configure option to interpose by default so that the interposer within a container is enabled by default and does not require setting the GSS_USE_PROXY env var, but will still respect an explicit no setting to avoid looping |

This mode is to be used in a user session where what we want to proxy is other applications run by the same user in a container or flatpak. This allows those application to use the user's creedntials w/o having to bind mount and expose the user TGT. The configuration is fixed and simplified, and the user proxy is allowed to be itself intercepted by the system proxy if desired. Use a subdirectory of XDG_RUNTIME_DIR by default If an explicit socket name is passed we expect the directory structure to be in place. However if we are dealing with XDG_RUNTIME_DIR then we want to create a subdirectory so that it can bind mounted in containers. Bind mounting the socket directly is problematic if we want to allow to restart the daemon as the socket may then become permanently disconnected in the container. If we use a subdirectory we need to attempt to create it on start because XDG_RUNTIME_DIR is ephemeral and generally recreated from scratch when the user session is created, so we need to populate it with the needed dir strcuture ourself to make things simpler for users.

This helps cases where only the client is needed, as it removes a bunch of dependencies needed only by the proxy daemon itself. Signed-off-by: Simo Sorce <simo@redhat.com>
Add Userproxy.md file that explains what user proxy mode is and how/when to use it. Add userproxy mode changes to manpages. Signed-off-by: Simo Sorce <simo@redhat.com>
This way we can provide a user systemd unit that will automatically starts gssproxy in user mode if someone tries to use the userproxy socket. Signed-off-by: Simo Sorce <simo@redhat.com>

This changes the example file name from "mech" to proxymech.conf and always installs this file. Downstreams have been already doing this for a long time, might as well do it upstream as well. Also tidy up install dirs when only the gss module is built. Signed-off-by: Simo Sorce <simo@redhat.com>

Manually tests with a modified flatpak that bind mounts the correct directories. |
