2019-02-18Bluetooth: remove redundant zero check on countColin Ian King
Variable count is never zero inside the loop so the check if count is zero is redundant and can be removed. Fix this. Detected by CoverityScan, CID#1466880 ("Logically dead code") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2019-01-22Bluetooth: hci_uart: Check if socket buffer is ERR_PTR in h4_recv_buf()Myungho Jung
h4_recv_buf() callers store the return value to socket buffer and recursively pass the buffer to h4_recv_buf() without protection. So, ERR_PTR returned from h4_recv_buf() can be dereferenced, if called again before setting the socket buffer to NULL from previous error. Check if skb is ERR_PTR in h4_recv_buf().

2018-04-01Bluetooth: bpa10x: Use separate h4_recv_buf helperMarcel Holtmann
When adding the alignment and padding support for H:4 packet processing for the Nokia driver, it broke the h4_recv_buf usage within bpa10x driver. To fix this use a separate helper function and placing it into a dedicated h4_recv.h header file.
