Hello! I'm fine with change below, but I would suggest to put more details into commit message. This change has nothing to do with wideband nor with exporting socket option to userspace -- which is already done via SCO_OPTIONS option. Also it is relevant to SCO socket with any codec data, not only wideband. This commit description should rather mention that it defines new getsockopt options BT_SNDMTU/BT_RCVMTU for SCO socket to be compatible with other bluetooth sockets and that these options return same value as option SCO_OPTIONS which is already present on existing kernels. > > Reviewed-by: Alain Michaud <alainm@xxxxxxxxxxxx> > Reviewed-by: Abhishek Pandit-Subedi <abhishekpandit@xxxxxxxxxxxx> > Signed-off-by: Joseph Hwang <josephsih@xxxxxxxxxxxx> > --- > > (no changes since v1) > > net/bluetooth/sco.c | 6 ++++++ > 1 file changed, 6 insertions(+) > > diff --git a/net/bluetooth/sco.c b/net/bluetooth/sco.c > index dcf7f96ff417e6..79ffcdef0b7ad5 100644 > --- a/net/bluetooth/sco.c > +++ b/net/bluetooth/sco.c > @@ -1001,6 +1001,12 @@ static int sco_sock_getsockopt(struct socket *sock, int level, int optname, > err = -EFAULT; > break; > > + case BT_SNDMTU: > + case BT_RCVMTU: > + if (put_user(sco_pi(sk)->conn->mtu, (u32 __user *)optval)) > + err = -EFAULT; > + break; > + > default: > err = -ENOPROTOOPT; > break; > -- > 2.28.0.526.ge36021eeef-goog >
