This patch defines new getsockopt options BT_SNDMTU/BT_RCVMTU for SCO socket to be compatible with other bluetooth sockets. These new options return the same value as option SCO_OPTIONS which is already present on existing kernels.

Changes in v2: - Used BT_SNDMTU/BT_RCVMTU instead of creating a new opt name. - Used the existing conn->mtu instead of creating a new member in struct sco_pinfo. - Noted that the old SCO_OPTIONS in sco_sock_getsockopt_old() would just work as it uses sco_pi(sk)->conn->mtu. 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; -- 2.28.0.618.gf4bc123cb7-goog
