Return-Path: From: Jakub Tyszkowski To: linux-bluetooth@vger.kernel.org Cc: Jakub Tyszkowski Subject: [PATCH 1/8] android/tester: Add action to verify encryption change Date: Wed, 3 Sep 2014 11:02:42 +0200 Message-Id: <1409734969-10716-1-git-send-email-jakub.tyszkowski@tieto.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: When encryption change is verified encryption flag is cleared so we can detect another encryption change when device reconnects during execution of another step in the same test case. --- android/tester-main.c | 38 ++++++++++++++++++++++++++++++++++++++ android/tester-main.h | 2 ++ 2 files changed, 40 insertions(+) diff --git a/android/tester-main.c b/android/tester-main.c index f5f46fb..34a71ac 100644 --- a/android/tester-main.c +++ b/android/tester-main.c @@ -28,6 +28,8 @@ static gint scheduled_cbacks_num; #define EMULATOR_SIGNAL_TIMEOUT 2 /* in seconds */ #define EMULATOR_SIGNAL "emulator_started" +static const uint8_t hci_encr_change_hdr[] = { 0x04, 0x08, 0x04, 0x00 }; + static gboolean check_callbacks_called(gpointer user_data) { /* @@ -213,6 +215,25 @@ static void mgmt_debug(const char *str, void *user_data) tester_print("%s%s", prefix, str); } +static bool hciemu_post_encr_hook(const void *data, uint16_t len, + void *user_data) +{ + struct test_data *t_data = tester_get_data(); + + /* + * Expected data: header (4 octets) + conn. handle (2 octets) + + * encryption flag (1 octet) + */ + if (len < sizeof(hci_encr_change_hdr) + 3) + return true; + + /* Verify header, skip conn. handle and check encryption */ + if (!memcmp(hci_encr_change_hdr, data, sizeof(hci_encr_change_hdr))) + t_data->is_encrypted = ((uint8_t *)data)[6] ? true : false; + + return true; +} + static void read_info_callback(uint8_t status, uint16_t length, const void *param, void *user_data) { @@ -250,6 +271,10 @@ static void read_info_callback(uint8_t status, uint16_t length, return; } + /* set hook for encryption change */ + hciemu_add_hook(data->hciemu, HCIEMU_HOOK_POST_EVT, 0x08, + hciemu_post_encr_hook, NULL); + tester_pre_setup_complete(); } @@ -1804,6 +1829,19 @@ void emu_add_l2cap_server_action(void) schedule_action_verification(step); } +void bt_verify_encryption_action(void) +{ + struct test_data *data = tester_get_data(); + struct step *step = g_new0(struct step, 1); + + step->action_status = data->is_encrypted ?
