Local extended features bitmask may change when Write LE Host Supported Command is sent by the kernel. This patch adds reading of the local extended features in the initialization sending a HCI command, extend the ioctl HCIGETDEVINFO is not suitable due possible inconsistency between kernel and userspace. --- plugins/hciops.c | 24 +++++++----------------- 1 files changed, 7 insertions(+), 17 deletions(-) diff --git a/plugins/hciops.c b/plugins/hciops.c index 0f8f79d..ddff544 100644 --- a/plugins/hciops.c +++ b/plugins/hciops.c @@ -1372,20 +1372,6 @@ static inline void remote_features_notify(int index, void *ptr) write_features_info(&dev->bdaddr, &evt->bdaddr, NULL, evt->features); } -static void write_le_host_complete(int index, uint8_t status) -{ - struct dev_info *dev = &devs[index]; - uint8_t page_num = 0x01; - - if (status) - return; - - if (hci_send_cmd(dev->sk, OGF_INFO_PARAM, - OCF_READ_LOCAL_EXT_FEATURES, 1, &page_num) < 0) - error("Unable to read extended local features: %s (%d)", - strerror(errno), errno); -} - static void read_local_version_complete(int index, const read_local_version_rp *rp) { @@ -1801,9 +1787,6 @@ static inline void cmd_complete(int index, void *ptr) case cmd_opcode_pack(OGF_LINK_CTL, OCF_INQUIRY_CANCEL): cc_inquiry_cancel(index, status); break; - case cmd_opcode_pack(OGF_HOST_CTL, OCF_WRITE_LE_HOST_SUPPORTED): - write_le_host_complete(index, status); - break; case cmd_opcode_pack(OGF_LE_CTL, OCF_LE_SET_SCAN_ENABLE): cc_le_set_scan_enable(index, status); break; @@ -2498,6 +2481,13 @@ static void device_devup_setup(int index) bacpy(&dev->bdaddr, &di.bdaddr); memcpy(dev->features, di.features, 8); + if (dev->features[7] & LMP_EXT_FEAT) { + uint8_t page_num = 0x01; + + hci_send_cmd(dev->sk, OGF_INFO_PARAM, + OCF_READ_LOCAL_EXT_FEATURES, 1, &page_num); + } + /* Set page timeout */ if ((main_opts.flags & (1 << HCID_SET_PAGETO))) { write_page_timeout_cp cp; -- 1.7.6 -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
