Smatch complains that some of these struct members are not initialized leading to a stack information disclosure: net/bluetooth/sco.c:778 sco_conn_defer_accept() warn: check that 'cp.retrans_effort' doesn't leak information This seems like a valid warning. I've added a default case to fix this issue. It's sort of unusual to have case SCO_AIRMODE_CVSD, followed by a default case but I think it's nicely readable. :) Fixes: 2f69a82acf6f ("Bluetooth: Use voice setting in deferred SCO connection request") Signed-off-by: Dan Carpenter <dan.carpenter@xxxxxxxxxx> --- net/bluetooth/sco.c | 1 + 1 file changed, 1 insertion(+) diff --git a/net/bluetooth/sco.c b/net/bluetooth/sco.c index d9a4e88dacbb..e2ee00fea64b 100644 --- a/net/bluetooth/sco.c +++ b/net/bluetooth/sco.c @@ -770,6 +770,7 @@ static void sco_conn_defer_accept(struct hci_conn *conn, u16 setting) cp.retrans_effort = 0x02; break; case SCO_AIRMODE_CVSD: + default: cp.max_latency = cpu_to_le16(0xffff); cp.retrans_effort = 0xff; break; -- 2.30.2
