Hi,
I have found a regression issue with latest kernel code. I am trying
to execute the test case for GAP TP/SEC/SEM/BV-10-C using BITE.
Below is the test purpose
5.4.4.6 TP/SEC/SEM/BV-10-C Security Mode 4 - Master
Verify that the IUT disconnects the connection if the initiating side
sends the L2CAP_ConnectReq without first enabling encryption. IUT has
2.1 Host and 2.1 Con-troller. Tester has 2.1 Host and 2.1 Controller.
As per my analysis,
1) Host is sending HCI Disconnect request before L2CAP_ConnectReq is
sent from BITE Tester (It sends it after 5 seconds).
2) This HCI Disconnect is initiated after 4 secs (approx), from host
side, since there is no other request received from Remote side after
creating ACL.
static inline void hci_conn_put(struct hci_conn *conn)
{
.......
if (conn->state == BT_CONNECTED) {
timeo = msecs_to_jiffies(conn->disc_timeout);
if (!conn->out)
timeo *= 2;
.......
}
Here conn->disc_timeout = HCI_DISCONN_TIMEOUT = 2 Secs.
I checked that this timeout has been changed in new kernel, and
earlier code, the mulitplication factor for incoming connection was
timeo *= 5 (20 even before).
After increasing the timeout for hci disconnect to more than 5
seconds, test case TP/SEC/SEM/BV-10-C passes.
Could you confirm if this is acceptable fix to pass the test case.
