  1. Fix PR 48104

    ozaki-r authored
    So far bridge cannot receive frames via a member interface when the frames
    come from another member interface. So when we assign an IP address to
    a member interface, hosts connected to another member interface cannot
    ping to the IP address. That behavior isn't expected. See PR 48104 for
    more realistic examples of this issue.
    
    The change does:
    - drop M_PROMISC before ether_input, which allows a bridge member interface
      to receive a frame coming from another bridge member interface
    - receive broadcast/multicast frames via all bridge member interfaces,
      which is required to receive IPv6 multicast packets destined to a
      multicast group belonging to a bridge member interface that is different
      from a packet arrival interface
    
    roy@ helped testing of the fix, thanks!

  1. Reform use of rt_refcnt

    ozaki-r authored
    rt_refcnt of rtentry was used in bad manners, for example, direct rt_refcnt++
    and rt_refcnt-- outside route.c, "rt->rt_refcnt++; rtfree(rt);" idiom, and
    touching rt after rt->rt_refcnt--.
    
    These abuses seem to be needed because rt_refcnt manages only references
    between rtentry and doesn't take care of references during packet processing
    (IOW references from local variables). In order to reduce the above abuses,
    the latter cases should be counted by rt_refcnt as well as the former cases.
    
    This change improves consistency of use of rt_refcnt:
    - rtentry is always accessed with rt_refcnt incremented
    - rtentry's rt_refcnt is decremented after use (rtfree is always used instead
      of rt_refcnt--)
    - functions returning rtentry increment its rt_refcnt (and caller rtfree it)
    
    Note that rt_refcnt prevents rtentry from being freed but doesn't prevent
    rtentry from being updated. Toward MP-safe, we need to provide another
    protection for rtentry, e.g., locks. (Or introduce a better data structure
    allowing concurrent readers during updates.)

  1. Use ip_hresolv_output for if_token as well

    ozaki-r authored
    I thought we cannot apply ip_hresolv_output to if_token because
    rt0 looked being needed by arpresolve in token_output. However,
    rt0 is actually not used by arpresolve in NetBSD (see obsolete
    ARPRESOLVE macro).

  1. Remove ifnet_addrs

    ozaki-r authored
    We can assume that ifnet_addrs[ifp->if_index] is always the same as
    ifp->if_dl, so we can replace ifnet_addrs[ifp->if_index] with ifp->if_dl
    and remove ifnet_addrs entirely.

  1. Pull out route lookups from L2 output routines

    ozaki-r authored
    Route lookups for routes of RTF_GATEWAY were done in L2 output
    routines such as ether_output, but they should be done in L3
    i.e., before L2 output routines. This change places the lookups
    between L3 output routines (say ip_output) and the L2 output
    routines.
    
    The change is based on dyoung's patch submitted in the thread:
    https://mail-index.netbsd.org/tech-net/2013/02/01/msg003847.html
    You can find out detailed investigations by dyoung about the
    issue in there.
    
    Note that the change introduces a workaround for MPLS. ether_output
    knew that it needs to fill the ethertype of a frame as MPLS,
    based on a tag of an original route (rtentry), but now we don't
    pass it to ehter_output. So we have to tell that in another way.
    We use mtag to do so for now, which introduces some overhead.
    We should fix it somehow in the future.
    
    Discussed on tech-kern and tech-net.
