From: Amit Pundir Date: Tue, 8 Dec 2015 12:58:40 +0000 (+0530) Subject: Hack: net: PPPoPNS and PPPoLAC build fixes for 4.1 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1af89c1ef3b64ef0b58c938e6bcc7d5e3415461b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git Hack: net: PPPoPNS and PPPoLAC build fixes for 4.1 Upstream commit c0371da6047a "put iov_iter into msghdr", added iov_iter and removed direct access to scatter/gather array elements in msghdr. It broke PPPoLAC and PPPoPNS. Lets restore the direct access to scatter/gather array in msghdr for the time being. Otherwise we run into following build failure: ---------- drivers/net/ppp/pppolac.c: In function ‘pppolac_xmit_core’: drivers/net/ppp/pppolac.c:210:4: error: unknown field ‘msg_iov’ specified in initializer .msg_iov = (struct iovec *)&iov, ^ drivers/net/ppp/pppolac.c:211:4: error: unknown field ‘msg_iovlen’ specified in initializer .msg_iovlen = 1, ^ make[3]: *** [drivers/net/ppp/pppolac.o] Error 1 ---------- Change-Id: I2a1245a156da6d93b49f5cfd10506381b0eff005 Signed-off-by: Amit Pundir Signed-off-by: Dmitry Shmidt --- diff --git a/include/linux/socket.h b/include/linux/socket.h index 5bf59c8493b7..18a8337c8959 100644 --- a/include/linux/socket.h +++ b/include/linux/socket.h @@ -47,6 +47,10 @@ struct linger { struct msghdr { void *msg_name; /* ptr to socket address structure */ int msg_namelen; /* size of socket address structure */ +#if defined(CONFIG_PPPOLAC) || defined(CONFIG_PPPOPNS) + struct iovec *msg_iov; /* scatter/gather array */ + __kernel_size_t msg_iovlen; /* # elements in msg_iov */ +#endif struct iov_iter msg_iter; /* data */ void *msg_control; /* ancillary data */ __kernel_size_t msg_controllen; /* ancillary data buffer length */
