![]() Add support for the option IPV6_<ADD|DROP>_MEMBERSHIP of the syscall setsockopt(). This option controls membership in multicast groups. Argument is a pointer to a struct ipv6_mreq. The glibc <netinet/in.h> header defines the ipv6_mreq structure, which includes the following members: struct in6_addr ipv6mr_multiaddr; unsigned int ipv6mr_interface; Whereas the kernel in its <linux/in6.h> header defines following members of the same structure: struct in6_addr ipv6mr_multiaddr; int ipv6mr_ifindex; POSIX defines ipv6mr_interface [1]. __UAPI_DEF_IVP6_MREQ appears in kernel headers with v3.12: cfd280c91253 net: sync some IP headers with glibc Without __UAPI_DEF_IVP6_MREQ, kernel defines ipv6mr_ifindex, and this is explained in cfd280c91253: "If you include the kernel headers first you get those, and if you include the glibc headers first you get those, and the following patch arranges a coordination and synchronization between the two." So before 3.12, a program can't include both <netinet/in.h> and <linux/in6.h>. In linux-user/syscall.c, we only include <netinet/in.h> (glibc) and not <linux/in6.h> (kernel headers), so ipv6mr_interface is the one to use.
