The feature is removed from the experimental features at the same time. Signed-off-by: Joseph Hwang --- Changes in v6: - No update in this patch. The patch 2/5 is updated to fix a sparse check warning. Changes in v5: - This patch becomes the first patch. - Remove useless hdev check in get_supported_settings(). - An additional patch will make quality report survive power off/on cycles. Changes in v4: - return current settings for set_quality_report. Changes in v3: - This is a new patch to enable the quality report feature. The reading and setting of the quality report feature are removed from the experimental features. include/net/bluetooth/mgmt.h | 7 ++ net/bluetooth/mgmt.c | 167 +++++++++++++++-------------------- 2 files changed, 80 insertions(+), 94 deletions(-) diff --git a/include/net/bluetooth/mgmt.h b/include/net/bluetooth/mgmt.h index 7c1ad0f6fcec..c1c2fd72d9e3 100644 --- a/include/net/bluetooth/mgmt.h +++ b/include/net/bluetooth/mgmt.h @@ -109,6 +109,7 @@ struct mgmt_rp_read_index_list { #define MGMT_SETTING_STATIC_ADDRESS 0x00008000 #define MGMT_SETTING_PHY_CONFIGURATION 0x00010000 #define MGMT_SETTING_WIDEBAND_SPEECH 0x00020000 +#define MGMT_SETTING_QUALITY_REPORT 0x00040000 #define MGMT_OP_READ_INFO 0x0004 #define MGMT_READ_INFO_SIZE 0 @@ -838,6 +839,12 @@ struct mgmt_cp_add_adv_patterns_monitor_rssi { } __packed; #define MGMT_ADD_ADV_PATTERNS_MONITOR_RSSI_SIZE 8 +#define MGMT_OP_SET_QUALITY_REPORT 0x0057 +struct mgmt_cp_set_quality_report { + __u8 action; +} __packed; +#define MGMT_SET_QUALITY_REPORT_SIZE 1 + #define MGMT_EV_CMD_COMPLETE 0x0001 struct mgmt_ev_cmd_complete { __le16 opcode; diff --git a/net/bluetooth/mgmt.c b/net/bluetooth/mgmt.c index d2d390534e54..1ad84f34097f 100644 --- a/net/bluetooth/mgmt.c +++ b/net/bluetooth/mgmt.c @@ -857,6 +857,9 @@ static u32 get_supported_settings(struct hci_dev *hdev) settings |= MGMT_SETTING_PHY_CONFIGURATION; + if (aosp_has_quality_report(hdev) || hdev->set_quality_report) + settings |= MGMT_SETTING_QUALITY_REPORT; + return settings; } @@ -928,6 +931,9 @@ static u32 get_current_settings(struct hci_dev *hdev) if (hci_dev_test_flag(hdev, HCI_WIDEBAND_SPEECH_ENABLED)) settings |= MGMT_SETTING_WIDEBAND_SPEECH; + if (hci_dev_test_flag(hdev, HCI_QUALITY_REPORT)) + settings |= MGMT_SETTING_QUALITY_REPORT; + return settings; } @@ -3901,12 +3907,6 @@ static const u8 debug_uuid[16] = { }; #endif -/* 330859bc-7506-492d-9370-9a6f0614037f */ -static const u8 quality_report_uuid[16] = { - 0x7f, 0x03, 0x14, 0x06, 0x6f, 0x9a, 0x70, 0x93, - 0x2d, 0x49, 0x06, 0x75, 0xbc, 0x59, 0x08, 0x33, -}; - /* a6695ace-ee7f-4fb9-881a-5fac66c629af */ static const u8 offload_codecs_uuid[16] = { 0xaf, 0x29, 0xc6, 0x66, 0xac, 0x5f, 0x1a, 0x88, @@ -3928,7 +3928,7 @@ static const u8 rpa_resolution_uuid[16] = { static int read_exp_features_info(struct sock *sk, struct hci_dev *hdev, void *data, u16 data_len) { - char buf[102]; /* Enough space for 5 features: 2 + 20 * 5 */ + char buf[82]; /* Enough space for 4 features: 2 + 20 * 4 */ struct mgmt_rp_read_exp_features_info *rp = (void *)buf; u16 idx = 0; u32 flags; @@ -3969,18 +3969,6 @@ static int read_exp_features_info(struct sock *sk, struct hci_dev *hdev, idx++; } - if (hdev && (aosp_has_quality_report(hdev) || - hdev->set_quality_report)) { - if (hci_dev_test_flag(hdev, HCI_QUALITY_REPORT)) - flags = BIT(0); - else - flags = 0; - - memcpy(rp->features[idx].uuid, quality_report_uuid, 16); - rp->features[idx].flags = cpu_to_le32(flags); - idx++; - } - if (hdev && hdev->get_data_path_id) { if (hci_dev_test_flag(hdev, HCI_OFFLOAD_CODECS_ENABLED)) flags = BIT(0); @@ -4193,80 +4181,6 @@ static int set_rpa_resolution_func(struct sock *sk, struct hci_dev *hdev, return err; } -static int set_quality_report_func(struct sock *sk, struct hci_dev *hdev, - struct mgmt_cp_set_exp_feature *cp, - u16 data_len) -{ - struct mgmt_rp_set_exp_feature rp; - bool val, changed; - int err; - - /* Command requires to use a valid controller index */ - if (!hdev) - return mgmt_cmd_status(sk, MGMT_INDEX_NONE, - MGMT_OP_SET_EXP_FEATURE, - MGMT_STATUS_INVALID_INDEX); - - /* Parameters are limited to a single octet */ - if (data_len != MGMT_SET_EXP_FEATURE_SIZE + 1) - return mgmt_cmd_status(sk, hdev->id, - MGMT_OP_SET_EXP_FEATURE, - MGMT_STATUS_INVALID_PARAMS); - - /* Only boolean on/off is supported */ - if (cp->param[0] != 0x00 && cp->param[0] != 0x01) - return mgmt_cmd_status(sk, hdev->id, - MGMT_OP_SET_EXP_FEATURE, - MGMT_STATUS_INVALID_PARAMS); - - hci_req_sync_lock(hdev); - - val = !!cp->param[0]; - changed = (val != hci_dev_test_flag(hdev, HCI_QUALITY_REPORT)); - - if (!aosp_has_quality_report(hdev) && !hdev->set_quality_report) { - err = mgmt_cmd_status(sk, hdev->id, - MGMT_OP_SET_EXP_FEATURE, - MGMT_STATUS_NOT_SUPPORTED); - goto unlock_quality_report; - } - - if (changed) { - if (hdev->set_quality_report) - err = hdev->set_quality_report(hdev, val); - else - err = aosp_set_quality_report(hdev, val); - - if (err) { - err = mgmt_cmd_status(sk, hdev->id, - MGMT_OP_SET_EXP_FEATURE, - MGMT_STATUS_FAILED); - goto unlock_quality_report; - } - - if (val) - hci_dev_set_flag(hdev, HCI_QUALITY_REPORT); - else - hci_dev_clear_flag(hdev, HCI_QUALITY_REPORT); - } - - bt_dev_dbg(hdev, "quality report enable %d changed %d", val, changed); - - memcpy(rp.uuid, quality_report_uuid, 16); - rp.flags = cpu_to_le32(val ?
