From d570560d3b014fa74027af598c95fb749e36fecc Mon Sep 17 00:00:00 2001 From: Pierre-Olivier Mercier Date: Sun, 28 Dec 2025 18:42:30 +0700 Subject: [PATCH] feat: Phase 4 - Connection Management MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented complete Wi-Fi connection flow with authentication. Phase 4: Connection Management - Created passphrase authentication dialog (ui/wifi_auth.c) - Network selection handler in popup - Integrated agent with passphrase dialog - Complete connection flow: select network → auth dialog → agent → iwd - Support for open and secured (WPA2/WPA3) networks - Proper async D-Bus message handling in agent Features: - Passphrase dialog with password entry widget - Minimum 8-character passphrase validation - Network selection from popup (click to connect) - Open networks connect directly without dialog - Secured networks (psk, 8021x) show auth dialog - Agent stores pending D-Bus message for async reply - Passphrase sent securely to iwd via D-Bus - Memory cleared after passphrase transmission - Cancel button sends proper error reply to iwd - Network type detection (open/psk/8021x) Connection Flow: 1. User clicks network in popup 2. Check security type 3. If open: connect directly 4. If secured: show passphrase dialog 5. User enters passphrase 6. Agent receives RequestPassphrase from iwd 7. Dialog shows for network 8. User clicks Connect 9. Agent sends passphrase to iwd 10. iwd handles connection Agent Improvements: - Stores pending D-Bus message for async reply - Properly returns NULL to indicate async handling - Sends passphrase via eldbus_message_method_return_new - Cancellation sends error reply to iwd - Integrates with UI dialog system Module size: 191KB (increased from 152KB) Total lines: ~2,900 across 20 files Next phase: Advanced Features (hidden networks, multiple adapters, error handling) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- src/e_mod_main.h | 3 + src/e_mod_popup.c | 42 ++++++++++- src/iwd/iwd_agent.c | 75 ++++++++++++++++--- src/iwd/iwd_agent.h | 1 + src/meson.build | 4 +- src/ui/wifi_auth.c | 171 ++++++++++++++++++++++++++++++++++++++++++++ src/ui/wifi_auth.h | 16 +++++ 7 files changed, 301 insertions(+), 11 deletions(-) create mode 100644 src/ui/wifi_auth.c create mode 100644 src/ui/wifi_auth.h diff --git a/src/e_mod_main.h b/src/e_mod_main.h index 1d7cafb..da354ce 100644 --- a/src/e_mod_main.h +++ b/src/e_mod_main.h @@ -83,6 +83,9 @@ void e_iwd_gadget_shutdown(void); void iwd_popup_new(Instance *inst); void iwd_popup_del(Instance *inst); +/* Auth dialog functions */ +#include "ui/wifi_auth.h" + /* D-Bus functions */ #include "iwd/iwd_dbus.h" #include "iwd/iwd_device.h" diff --git a/src/e_mod_popup.c b/src/e_mod_popup.c index 1c01417..a4f912d 100644 --- a/src/e_mod_popup.c +++ b/src/e_mod_popup.c @@ -5,6 +5,7 @@ static void _popup_comp_del_cb(void *data, Evas_Object *obj); static void _button_rescan_cb(void *data, Evas_Object *obj, void *event_info); static void _button_disconnect_cb(void *data, Evas_Object *obj, void *event_info); static Eina_Bool _popup_reopen_cb(void *data); +static void _network_selected_cb(void *data, Evas_Object *obj, void *event_info); /* Create popup */ void @@ -113,7 +114,7 @@ iwd_popup_new(Instance *inst) net->name, security, net->known ?
