This code is copied > from rfcomm_sock_recvmsg() with minimal modifications to remove > RFCOMM-specific functionality and improve readability. > > L2CAP (with the SOCK_STREAM socket type) and RFCOMM have common needs > when it comes to reading data. Proper stream read semantics require > that applications can read from a stream one byte at a time and not > lose any data. The RFCOMM code already operated on and pulled data > from the underlying L2CAP socket, so very few changes were required to > make the code more generic for use with non-RFCOMM data over L2CAP. > > Applications that need more awareness of L2CAP frame boundaries are > still free to use SOCK_SEQPACKET sockets, and may verify that they > connection did not fall back to basic mode by calling getsockopt(). > > Signed-off-by: Mat Martineau <mathewm@xxxxxxxxxxxxxx> > --- > include/net/bluetooth/bluetooth.h | 2 + > net/bluetooth/af_bluetooth.c | 109 +++++++++++++++++++++++++++++++++++++ > 2 files changed, 111 insertions(+), 0 deletions(-) Acked-by: Gustavo F.
