Make A2MP channel special channel which do not reference hci_conn. This prevents from keeping ACL connection open when all L2CAP channels got closed. hci_conn_hold and hci_conn_put are not reference counts on the hci_conn structure in the typical way. They are reference counts for the ACL. When you do the last hci_conn_put, the ACL is disconnected after a timeout. Reported-by:

Sometimes an ACL link must be raised to a higher security level after an L2CAP connection is requested, but before a connection response is sent. In this case, a connection response sent by L2CAP was not immediately followed by a configuration request. Other code paths do send this configuration request right away. It was possible for the connection to stall while L2CAP waited for the remote device (like PTS) to trigger the configuration process. Here is an abbreviated hcidump of the failure case with PTS: 1337806446.051982 > ACL data: handle 43 flags 0x02 dlen 10 L2CAP(s): Info req: type 2 1337806446.052050 < ACL data: handle 43 flags 0x00 dlen 16 L2CAP(s): Info rsp: type 2 result 0 Extended feature mask 0x000000b8 1337806446.595320 > ACL data: handle 43 flags 0x02 dlen 12 L2CAP(s): Connect req: psm 4097 scid 0x0041 1337806446.595673 < ACL data: handle 43 flags 0x00 dlen 16 L2CAP(s): Connect rsp: dcid 0x0040 scid 0x0041 result 1 status 0 1337806446.595679 < ACL data: handle 43 flags 0x00 dlen 10 L2CAP(s): Info req: type 2 1337806446.669835 > ACL data: handle 43 flags 0x02 dlen 16 L2CAP(s): Info rsp: type 2 result 0 Extended feature mask 0x00000028 1337806446.669899 < HCI Command: Authentication Requested (0x01|0x0011) plen 2 1337806446.669906 < ACL data: handle 43 flags 0x00 dlen 16 L2CAP(s): Connect rsp: dcid 0x0040 scid 0x0041 result 1 status 1 <security setup here> 1337806446.769888 < ACL data: handle 43 flags 0x00 dlen 16 L2CAP(s): Connect rsp: dcid 0x0040 scid 0x0041 result 0 status 0 At this point, the connection stalls and no further messages are sent on the L2CAP signaling channel. No data is received either.
