Bluetooth: hci_event: Detect if HCI_EV_NUM_COMP_PKTS is unbalanced

Browse source

[ Upstream commit 15bf2c6391 ]

This attempts to detect if HCI_EV_NUM_COMP_PKTS contain an unbalanced
(more than currently considered outstanding) number of packets otherwise
it could cause the hcon->sent to underflow and loop around breaking the
tracking of the outstanding packets pending acknowledgment.
