Also, it update the size of white list and resolving list to 1 more than actual size when it is read via HCI read size commands. This is used to simulate the case when the list is out of space. Note that the read list size may not represent the current actual list size depends on the device vendor. --- emulator/btdev.c | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-) diff --git a/emulator/btdev.c b/emulator/btdev.c index a7fda2c89..75cca7549 100644 --- a/emulator/btdev.c +++ b/emulator/btdev.c @@ -33,8 +33,8 @@ #include "monitor/bt.h" #include "btdev.h" -#define WL_SIZE 16 -#define RL_SIZE 16 +#define WL_SIZE 3 +#define RL_SIZE 3 #define CIS_SIZE 3 #define has_bredr(btdev) (!((btdev)->features[4] & 0x20)) @@ -3404,7 +3404,12 @@ static int cmd_read_wl_size(struct btdev *dev, const void *data, uint8_t len) struct bt_hci_rsp_le_read_white_list_size rsp; rsp.status = BT_HCI_ERR_SUCCESS; - rsp.size = WL_SIZE; + /* The size is not fixed and the actual list size can be different from + * the returned size here. + * In order to test such cases, return more than allocated size, and + * HCI Add device cmd will return the Memory Capacity Exceeded(0x07) + */ + rsp.size = WL_SIZE + 1; cmd_complete(dev, BT_HCI_CMD_LE_READ_WHITE_LIST_SIZE, &rsp, sizeof(rsp)); @@ -3689,7 +3694,12 @@ static int cmd_read_rl_size(struct btdev *dev, const void *data, uint8_t len) struct bt_hci_rsp_le_read_resolv_list_size rsp; rsp.status = BT_HCI_ERR_SUCCESS; - rsp.size = RL_SIZE; + /* The size is not fixed and the actual list size can be different from + * the returned size here. + * In order to test such cases, return more than allocated size, and + * HCI Add device cmd will return the Memory Capacity Exceeded(0x07) + */ + rsp.size = RL_SIZE + 1; cmd_complete(dev, BT_HCI_CMD_LE_READ_RESOLV_LIST_SIZE, &rsp, sizeof(rsp));
