            Bug ID: 18233
           Summary: msghdr and cmsghdr types are not POSIX conform in
                    sys/socket.h
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: nszabolcs at gmail dot com
                CC: drepper.fsp at gmail dot com

msg_iovlen, msg_controllen and cmsg_len have wrong types

http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/sys_socket.h.html

the following code fails on linux:

#define _POSIX_C_SOURCE 200809L
#include <sys/socket.h>
void f()
{
struct msghdr x;
struct cmsghdr y;
int *p = &x.msg_iovlen; // warning: initialization from incompatible pointer
type [enabled by default]
socklen_t *q = &x.msg_controllen; // likewise
socklen_t *r = &y.cmsg_len;
}
