The implementation adds socket options at SOL_PNPIPE level: - PNPIPE_PIPE_HANDLE - It accepts an integer argument for setting value of pipe handle. - PNPIPE_ENABLE accepts one integer value (int). If set to zero, the pipe is disabled. If the value is non-zero, the pipe is enabled. If the pipe is not (yet) connected, ENOTCONN is error is returned. diff --git a/include/linux/phonet.h b/include/linux/phonet.h index 26c8df786918..32a0965da953 100644 --- a/include/linux/phonet.h +++ b/include/linux/phonet.h @@ -36,7 +36,7 @@ /* Socket options for SOL_PNPIPE level */ #define PNPIPE_ENCAP 1 #define PNPIPE_IFINDEX 2 -#define PNPIPE_PIPE_HANDLE 3 +#define PNPIPE_HANDLE 3 #define PNPIPE_ENABLE 4 /* unused slot */ diff --git a/net/phonet/pep.c b/net/phonet/pep.c index c0fab4cfcef7..abfb795af142 100644 --- a/net/phonet/pep.c +++ b/net/phonet/pep.c @@ -853,6 +853,7 @@ static int pep_sock_connect(struct sock *sk, struct sockaddr *addr, int len) pn->pn_sk.dobject = pn_sockaddr_get_object(spn); pn->pn_sk.resource = pn_sockaddr_get_resource(spn); + pn->pipe_handle = 1; /* anything but INVALID_HANDLE */ return pipe_handler_request(sk, PNS_PEP_CONNECT_REQ, PN_PIPE_DISABLE, data, 4); } @@ -909,14 +910,6 @@ static int pep_setsockopt(struct sock *sk, int level, int optname, lock_sock(sk); switch (optname) { -#ifdef CONFIG_PHONET_PIPECTRLR - case PNPIPE_PIPE_HANDLE: - if (val) { - pn->pipe_handle = val; - break; - } -#endif - case PNPIPE_ENCAP: if (val && val != PNPIPE_ENCAP_IP) { err = -EINVAL; @@ -982,6 +975,12 @@ static int pep_getsockopt(struct sock *sk, int level, int optname, val = pn->ifindex; break; + case PNPIPE_HANDLE: + val = pn->pipe_handle; + if (val == PN_PIPE_INVALID_HANDLE) + return -EINVAL; + break; + #ifdef CONFIG_PHONET_PIPECTRLR case PNPIPE_ENABLE: val = sk->sk_state == TCP_ESTABLISHED; |
