Hi Archie, > Whenever we disconnect a L2CAP connection, we would immediately > report a disconnection event (EPOLLHUP) to the upper layer, without > waiting for the response of the other device. > > This patch offers an option to wait until we receive a disconnection > response before reporting disconnection event, by using the "how" > parameter in l2cap_sock_shutdown(). Therefore, upper layer can opt > to wait for disconnection response by shutdown(sock, SHUT_WR). > > This can be used to enforce proper disconnection order in HID, > where the disconnection of the interrupt channel must be complete > before attempting to disconnect the control channel. > > Signed-off-by: Archie Pusaka <apusaka@xxxxxxxxxxxx> > --- > > net/bluetooth/l2cap_sock.c | 30 +++++++++++++++++++++++------- > 1 file changed, 23 insertions(+), 7 deletions(-) patch has been applied to bluetooth-next tree.
