CVS log for kame/kame/sys/net/Attic/if_hif.c

New Mobile IPv6 code which also supports NEMO.

removed a "malloc() failure" warning message at start-up time on freebsd5.

(M_WAIT(mbuf flag) is equal to M_WAITOK(malloc() flag) in every BSD
 except freebsd5, so this problem occurs only in freebsd5)

more #ifdef cleanups

the name of watari was misprinted.

restructure of header files based on draft-ietf-mip6-mipext-advapi-00.

MIP6 fix regarding to back to embeded style.
some parts worked, some not yet...

MIP6: send a mobile prefix solicitation when a mobile node receives
an unsoclcited mobilt prefix advertisement message.

Don't use pointers as parameters of ioctl() for mobile node configuration
The data that they point are not copied to kernel land.

code clean up.

fixed a bug in initializing dhaad initial id value.

do not select link-local address as a home agent address.

- support for changing home agent.

- removed duplicated function.

- changed TAILQ to LIST to manage the hif list since it need not to be.

- changed mip6_ha list management from LIST to TAILQ, since we need
  to insert both head and tail based on the pref value of the entry.

- restructure mobile ip related prefix management to support
  multiple global addresses of home agents.

- sending MPS and reccieving MPA.
  the code is just a starting point, and far from complete.

- sync with Freebsd 5.1-RELEASE
- removed FreeBSD-specific ifdef for M_MOVE_PKTHDR(), since all *BSDs have M_MOVE_PKTHDR() now

fixed a memory leak when disabling mn function.

less warning(MIP6).

- added experimental firewall bypassing scheme.

- assign a CoA separately for each hif interface.

- fixed the type of return value of management functions for struct hif_ha.

- simplify the prefix and advertising route management on a mobile node.

removed unused functions.

- restructured mip6 code.
  divided cn/ha/mn part to separate files.  this makes it easier to
  merge a paticular part (ex. CN) to original BSD or to integrate
  a paticular part (ex. HA) to routers.

makes it compilable on freebsd4.8

remove "m->m_flags &= ~M_PKTHDR" when m becomes an intermediate mbuf in a
mbuf chain.  it is safer this way.

make it compilable on freebsd5

- delete mtags when we drop the M_PKTHDR flag by hand ('by hand' means not
  using M_MOVE_PKTHDR).
  such an operation should be avoided whenever it is possible...

- fixed typemismatch of arguments to ip6_setpktaddrs().

Make it compilable on NetBSD (and maybe other BSDs) along the changes
regarding freebsd5 and ip6_getpktaddrs().

- mtag fix.

fixed a bug that some interfaces cannot be manipulated under OpenBSD+KAME.

MIP6: cn's site-local address be tunneled to HA

- renamed some structures and macros.  no code changes.

MIP6: site-local CoA not supported

typo if_dlt (sorry)

initialize if_dlt and if_sadl on netbsd 1.6

sync w/ 1.6.  GENERIC.KAME/i386 compiles, not tested.
- NATPT and IP6FW support were dropped (you can use ipfilter).
- altq, ecn, RTF_CACHE, SCOPEDROUTING need checking

KNF - return is not a function.

MIP6: sanity check for outer dst addr

- added stat entries for reverse tunnel in/output.

- a global variable should be defined in a .c file

openbsd too uses splsoftnet

- a newly created mha must be inserted to the ha list.
  reported from karino@nec.

- the first step for mip6 id17 support.
  this commit is for the KAME mip6 developpers.  do not try to use this.

- added a rate limitation logic when sending DHAAD requests.

- change the mtu size of the hif i/f from 1500 to 1280.

- use IPV6_MINMTU when sending to the reverse tunnel.
  XXX

- add bidirectional tunneling.  if the peer node doesn't support MIP6 (that
  is, doesn't understand HAO), the MN automatically tunnels the packets to
  the peer via HA.
  to use BDT, specify 'options MIP6_BDT'.
  currently, MIP6_BDT cannot be specified in conjunction with
  MIP6_ALLOW_COA_FALLBACK.

- a static home address assignment.
  specify 'options MIP6_STATIC_HADDR' and use 'mip6control -I ifid' to set
  ifid.  this is very experimental.

make mip6 code scope aware.
need more work...

- remove printf for debug purpose.

- remove the home prefix information and the home agent list when
  mip6control -M.

- fogot to commit in the previous my commit.

remove opt_inet6.h,mip6_var.h&etc. includes from if_hif.h&mip6.h

	- do movement detection in the prefix_onlink_check()
	  instead of nd6_ra_input().

	- remove hif_rtrequest.

	- fix incorrect ifa_rtrequest setting in hif_ioctl.
	- change the movement detection algorithm from prefix based to
	  coa address changing based.

	- modify mip6_prefix to hold vltime and pltime.
	- bu flags based on draft15.
	- icmp numbers bsed on draft15.

supported SIOCADDMULTI in hit_ioctl

	- protected the mip6 ioctl path by splnet() during retreiving
	  binding cache entries.
	- changed the mip6 ioctl request structure. (this requires updating
	  the mip6control command you are using.)

replace __FUNCTION__ with __LINE__ and __FILE__.

remove unused old code.

remove old code.

fix throwback...

type __FreeBSD_ -> __FreeBSD__

make it compile on netbsd.  not tested

remove XXX_FOREACH.

there's no need for us to pullup mbuf chain if PULLDOWN_TEST is defined

add mobileip source code.

currently, many parts of spec are not implemented yet.  even
uncompilable under other than freebsd4 now.  also very unstable.
of course, without MIP6 kernel option, there is no problem. all mip6
related code is separated by ifdef MIP6.

this integration is just for KAME mip6 developper's convinience.
the purpose of this early integration is to decrease the maintenance cost
to synchronize KAME main tree and developping mip6 tree.  after this merge,
mip6 code modifications are reflected directly to KAME code.

i will make these codes compilable on the other OSes as soon as possible.
