[Lksctp-developers] fix proposal sctp_getladdrs

[Florian N. <flo...@st...>]

Hi,
sctp_getladdrs kann result in a crash if the return address is reused 
after. For security reasons I propose to set "addrs=NULL". Otherwise a 
misbehavior can be achieved with a second free() on the returned address.

int
sctp_freeladdrs(struct sockaddr *addrs)
{
    free(addrs);
    return 0;

} /* sctp_freeladdrs() */


proposal:

int
sctp_freeladdrs(struct sockaddr *addrs)
{
    free(addrs);
    addrs=NULL;
    return 0;

} /* sctp_freeladdrs() */
