           Summary: RTNLGRP_ND_USEROPT does not report ifindex
           Product: Networking
           Version: 2.5
     KernelVersion: 2.6.24-rc
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: IPV6
        AssignedTo: [email protected]
        ReportedBy: [email protected]

Most recent kernel where this bug did not occur: none
Distribution: N/A
Hardware Environment: any
Software Environment: any
Problem Description:
The RTNLGRP_ND_USEROPT NetLink message introduced in 2.6.24 does not seem to include any information as to which netif the user options come from:

struct nduseroptmsg

{
        unsigned char   nduseropt_family;
        unsigned char   nduseropt_pad1;
        unsigned short  nduseropt_opts_len; /* Total length of options */
        __u8            nduseropt_icmp_type;
        __u8            nduseropt_icmp_code;
        unsigned short  nduseropt_pad2;
        /* Followed by one or more ND options */
};

Considering this is meant to carry data that is heavily link-layer involved, this seems like a feature bug. Could an ifindex field be added there??

Ok, I am seeing to this.
