Define NAMESPACE_D_DIR and NAMESPACE_D_GLOB. Define new option flags and polydir flags. (polydir_s): Add rdir, replace exclusive with flags, add init_script, owner, group, and mode. (instance_data): Add ruser, gid, and ruid. * modules/pam_namespace/pam_namespace.c: Remove now unused copy_ent(). (add_polydir_entry): Add the entry directly, no copy. (del_polydir): New function. (del_polydir_list): Call del_polydir(). (expand_variables, parse_create_params, parse_iscript_params, parse_method): New functions. (process_line): Call expand_variables() on polydir and instance prefix. Call argv_parse() instead of strtok_r(). Allocate struct polydir_s on heap. (parse_config_file): Parse .conf files from namespace.d dir after namespace.conf. (form_context): Call getcon() or get_default_context_with_level() when appropriate flags are set. (poly_name): Handle shared polydir flag. (inst_init): Execute non-default init script when specified. (create_polydir): New function. (create_dirs): Remove the code which checks the polydir. Do not call inst_init() when noinit flag is set. (ns_setup): Check the polydir and eventually create it if the create flag is set. (setup_namespace): Use ruser uid from idata. Set the namespace polydir pam data only when namespace was set up correctly. Unmount polydir based on ruser. (get_user_data): New function. (pam_sm_open_session): Check for use_current_context and use_default_context options. Call get_user_data(). (pam_sm_close_session): Call get_user_data().

Add home directory initialization script. * modules/pam_namespace/pam_namespace.8.xml: Document the new init parameter of the namespace.init script. * modules/pam_namespace/pam_namespace.c(copy_ent): Copy exclusive flag. (cleanup_data): New function. (process_line): Set exclusive flag. Add tmpfs and tmpdir methods. (ns_override): Change behavior on the exclusive flag. (poly_name): Process tmpfs and tmpdir methods. (inst_init): Add flag for new directory initialization. (create_dirs): Process the tmpdir method, add the new directory flag. (ns_setup): Remove unused code. Process the tmpfs method. (cleanup_tmpdirs): New function. (setup_namespace): Set data for proper cleanup. Cleanup the tmpdirs on failures. (pam_sm_close_session): Instead of parsing the config file again use the previously set data for cleanup. * modules/pam_namespace/pam_namespace.h: Add TMPFS and TMPDIR methods and exclusive flag.

Fix crash on unknown override user in config file. (ns_override): Add explicit uid parameter. (form_context): Skip for user method. Implement level based polyinstantiation. (poly_name): Initialize contexts. Add level based polyinst, remove 'both' metod. Use raw contexts for instance names, truncate long instance names and add hash. (ns_setup): Hashing moved to poly_name(). (setup_namespace): Handle correctly override users for su (when unmnt_remnt is used). (pam_sm_close_session): Added no_unmount_on_close option. * modules/pam_namespace/pam_namespace.h: Added no_unmount_on_close_option, level method, limit on instance directory name length.
