> L2CAP ERTM sockets can be opened with the SOCK_STREAM socket type, > which is a mandatory request for ERTM mode. > > However, these sockets still have SOCK_SEQPACKET read semantics when > bt_sock_recvmsg() is used to pull data from the receive queue. If the > application is only reading part of a frame, then the unread portion > of the frame is discarded.

The application may read one > byte at a time from the input stream and not lose any data, and may > also read across L2CAP frame boundaries. > > Signed-off-by: Mat Martineau <[email protected]> > --- > net/bluetooth/l2cap.c | 3 +++ > 1 files changed, 3 insertions(+), 0 deletions(-) Acked-by: Gustavo F.
