Eric Dumazet d198b27762 Revert "Revert "ipv4: fix memory leaks in ip_cmsg_send() callers"" ... This reverts commit d7807a9adf. As mentioned in https://lkml.org/lkml/2021/9/13/1819 5 years old commit 919483096b ("ipv4: fix memory leaks in ip_cmsg_send() callers") was a correct fix. ip_cmsg_send() can loop over multiple cmsghdr() If IP_RETOPTS has been successful, but following cmsghdr generates an error, we do not free ipc.ok If IP_RETOPTS is not successful, we have freed the allocated temporary space, not the one currently in ipc.opt. Sure, code could be refactored, but let's not bring back old bugs.
