324ea0e22c Implement a mechanism by which ATM drivers can inform interested
parts of the system about certain kinds of events, like changes
in the ABR rate, changes in the carrier state, PVC changes. The
main consumers of these events are the harp(4) pseudo-driver
and the ILMI daemon via ng_atm(4).

19480bfa11 Move the MAC entry point to label ethernet-sourced mbufs with a MAC label
from the network interface earlier in ether_input().  At some point
(no fingers pointed), things were restructured and the labeling operation
moved later.  This wasn't a problem as BPF_MTAP() relies on the ifnet
label not the mbuf label, but there might have been other problems.

28f4067fe0 - In vlan_input(), always mask off all but the VLID bits from tags
extracted from received frames, both in the IFCAP_VLAN_HWTAGGING case
  and not. (Some drivers may already do this masking internally, but
  doing it here doesn't hurt and insures consistency.)

- In vlan_ioctl(), don't let the user set a VLAN ID value with anything
  besides the VLID bits set, otherwise we will have trouble matching
  an interface in vlan_input() later.

0721598de2 Testing VLANs with the new 8139C+ chip (which does hardware tag
insertion and extraction) has revealed two bugs:

- In vlan_start(), we're supposed to check the underlying interface to
  see if it has the IFCAP_VLAN_HWTAGGING cabability set and, if so, set
  things up for the VLAN_OUTPUT_TAG() routine. However the code checks
  ifp->if_capabilities, which is the vlan pseudo-interface's capabilities
  when it should be checking p->if_capabilities, which relates to the
  underlying physical interface. Change ifp->if_capabilities to
  p->if_capabilities so this works.

- In vlan_input(), we have to extract the 16-bit tag value from the
  received frame and use it to figure out which vlan interface gets
  the frame. The code that we use to track down the desired vlan
  pseudo-interface is:

       for (ifv = LIST_FIRST(&ifv_list); ifv != NULL;
            ifv = LIST_NEXT(ifv, ifv_list))
                if (ifp == ifv->ifv_p && tag == ifv->ifv_tag)
                        break;

  The problem is that 'tag' is not computed consistently. In the case
  where the interface supports hardware VLAN tag extraction and calls
  VLAN_INPUT_TAG(), we do this:

                tag = *(u_int*)(mtag+1);

  But in the software emulation case, we do this

                tag = EVL_VLANOFTAG(ntohs(evl->evl_tag));

  The problem here is the EVL_VLANOFTAG() macro is only ever applied
  in this one case. It's never applied to ifv->ifv_tag or anwhere else.
  We must be consistent: either it's applied everywhere or nowhere.
  To see how this can be a problem, do something like
  ifconfig vlan0 vlan 12345 vlandev foo0 and observe the results.

  I'm not quite sure what the right thing is to do here. Neither the
  vlan(4) nor ifconfig(8) man pages suggest which way to go. For now,
  I've removed this use of EVL_VLANOFTAG() so that the tag will match
  correctly in all cases. I will not get upset if somebody makes a
  compelling argument for using EVL_VLANOFTAG() everywhere instead,
  as long as the use is consistent.

b09db08f24 Replace a handrolled defrag function with m_defrag. The handrolled
function couldn't handle chains of > MCLBYTES, and it had a bug which
caused corruption and panics in certain low mbuf situations.

Additionally, change the failure case so that looutput returns ENOBUFS
rather than attempting to pass on non-defragmented mbuf chains.

Finally, remove the printf which would happen every time the low memory
situation occured.  It served no useful purpose other than to clue me
in as to what was causing the panic in question. :)

434086177f Add module data and version to the atm_subr and reference this info from the
(currently) only consumer (en).

Add a sysctl node hw.atm where the atm drivers will hook on their hardware
sysctl sub-trees.

Make atm_ifattach call if_attach and remove the corresponding call to if_attach
from en. Create atm_ifdetach and use that in en.

While the last change actually changes the interface this is not a problem in
practice because the only other consumer of this API is an older LANAI driver
on the net, that is not ready for current anyway.

53a050aac3 Move MAC label storage for mbufs into m_tags from the m_pkthdr structure,
returning some additional room in the first mbuf in a chain, and
avoiding feature-specific contents in the mbuf header.  To do this:

- Modify mbuf_to_label() to extract the tag, returning NULL if not
  found.

- Introduce mac_init_mbuf_tag() which does most of the work
  mac_init_mbuf() used to do, except on an m_tag rather than an
  mbuf.

- Scale back mac_init_mbuf() to perform m_tag allocation and invoke
  mac_init_mbuf_tag().

- Replace mac_destroy_mbuf() with mac_destroy_mbuf_tag(), since
  m_tag's are now GC'd deep in the m_tag/mbuf code rather than
  at a higher level when mbufs are directly free()'d.

- Add mac_copy_mbuf_tag() to support m_copy_pkthdr() and related
  notions.

- Generally change all references to mbuf labels so that they use
  mbuf_to_label() rather than &mbuf->m_pkthdr.label.  This
  required no changes in the MAC policies (yay!).

- Tweak mbuf release routines to not call mac_destroy_mbuf(),
  tag destruction takes care of it for us now.

- Remove MAC magic from m_copy_pkthdr() and m_move_pkthdr() --
  the existing m_tag support does all this for us.  Note that
  we can no longer just zero the m_tag list on the target mbuf,
  rather, we have to delete the chain because m_tag's will
  already be hung off freshly allocated mbuf's.

- Tweak m_tag copying routines so that if we're copying a MAC
  m_tag, we don't do a binary copy, rather, we initialize the
  new storage and do a deep copy of the label.

- Remove use of MAC_FLAG_INITIALIZED in a few bizarre places
  having to do with mbuf header copies previously.

- When an mbuf is copied in ip_input(), we no longer need to
  explicitly copy the label because it will get handled by the
  m_tag code now.

- No longer any weird handling of MAC labels in if_loop.c during
  header copies.

- Add MPC_LOADTIME_FLAG_LABELMBUFS flag to Biba, MLS, mac_test.
  In mac_test, handle the label==NULL case, since it can be
  dynamically loaded.

In order to improve performance with this change, introduce the notion
of "lazy MAC label allocation" -- only allocate m_tag storage for MAC
labels if we're running with a policy that uses MAC labels on mbufs.
Policies declare this intent by setting the MPC_LOADTIME_FLAG_LABELMBUFS
flag in their load-time flags field during declaration.  Note: this
opens up the possibility of post-boot policy modules getting back NULL
slot entries even though they have policy invariants of non-NULL slot
entries, as the policy might have been loaded after the mbuf was
allocated, leaving the mbuf without label storage.  Policies that cannot
handle this case must be declared as NOTLATE, or must be modified.

- mac_labelmbufs holds the current cumulative status as to whether
  any policies require mbuf labeling or not.  This is updated whenever
  the active policy set changes by the function mac_policy_updateflags().
  The function iterates the list and checks whether any have the
  flag set.  Write access to this variable is protected by the policy
  list; read access is currently not protected for performance reasons.
  This might change if it causes problems.

- Add MAC_POLICY_LIST_ASSERT_EXCLUSIVE() to permit the flags update
  function to assert appropriate locks.

- This makes allocation in mac_init_mbuf() conditional on the flag.
