itojun c00fa8dfd9 avoid swapping endian of ip_len and ip_off on mbuf, to meet with M_LEADINGSPACE
optimization made last year.  should solve PR 17867 and 10195.

IP_HDRINCL behavior of raw ip socket is kept unchanged.  we may want to
provide IP_HDRINCL variant that does not swap endian.

wiz 4c99916337 va_{start,end} audit:
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

Improved by comments from enami and christos -- thanks!

Heimdal/krb4/KAME changes already fed back, rest to follow.

Inspired by, but not not based on, OpenBSD.

itojun 4d51fe368b change the meaning of ifnet.if_lastchange to meet RFC1573 ifLastChange.
follows BSD/OS practice and ucd-snmp code (FreeBSD does it for specific
interfaces only).

was: if_lastchange get updated on every packet transmission/receipt.
now: if_lastchange get updated when IFF_UP is changed.

itojun 2d9097af9e correct typecast for eonrtrequest 3rd arg. 2001-01-17 15:13:37 +00:00
itojun df9784d749 pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2 (UCB copyrighted).
have sys/net/route.c:rtrequest1(), which takes rt_addrinfo * as the argument.
pass rt_addrinfo all the way down to rtrequest, and ifa->ifa_rtrequest.
3rd arg of ifa->ifa_rtrequest is now rt_addrinfo * instead of sockaddr *
(almost noone is using it anyways).

benefit: the follwoing command now works.  previously we need two route(8)
invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

remove unsafe typecast in rtrequest(), from rtentry * to sockaddr *.  it was
introduced by 4.3BSD-reno and never corrected.

XXX is eon_rtrequest() change correct regarding to 3rd arg?
eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno,
so i do not have correct answer in the source code.
someone with more clue about netiso-over-ip, please help.

thorpej fc5dafc79b Fix a rather annoying problem where the sockaddr_dl which holds
the link level name for the interface (ifp->if_sadl) is allocated
before ifp->if_addrlen is initialized, which could lead to allocating
too little space for the link level address.

Do this by splitting allocation of the link level name out of
if_attach() and into if_alloc_sadl(), which is normally called
by functions like ether_ifattach().  Network interfaces which
don't have a link-specific attach routine must call if_alloc_sadl()
themselves (example: gif).

Link level names are freed by if_free_sadl(), which can be called
from e.g. ether_ifdetach().  Drivers never need call if_free_sadl()
themselves as if_detach() will do it if it is not already done.

While here, add the ability to pass an AF_LINK address to
SIOCSIFADDR in ether_ioctl() (this is what caused me to notice
the problem that the above fixes).

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

itojun 04ac848d6f introduce m->m_pkthdr.aux to hold random data which needs to be passed
between protocol handlers.

ipsec socket pointers, ipsec decryption/auth information, tunnel
decapsulation information are in my mind - there can be several other usage.
at this moment, we use this for ipsec socket pointer passing.  this will
avoid reuse of m->m_pkthdr.rcvif in ipsec code.

due to the change, MHLEN will be decreased by sizeof(void *) - for example,
for i386, MHLEN was 100 bytes, but is now 96 bytes.
we may want to increase MSIZE from 128 to 256 for some of our architectures.

take caution if you use it for keeping some data item for long period
of time - use extra caution on M_PREPEND() or m_adj(), as they may result
in loss of m->m_pkthdr.aux pointer (and mbuf leak).

this will bump kernel version.

(as discussed in tech-net, tested in kame tree)

itojun d142237f2a clear m_pkthdr for M_PKTHDR mbuf, so that we do not get panic with
old data in pointer fields.  NOTE: we'll extend m_pkthdr field soon.

why does the code allocate mbuf by its own?

thorpej c1185c1020 PRU_PURGEADDR -> PRU_PURGEIF, per a discussion w/ itojun. In the IPv4
and IPv6 code, also use this to traverse PCB tables, looking for cached
routes referencing the dying ifnet, forcing them to be refreshed.

thorpej d844a3ac41 First-draft if_detach() implementation, originally from Bill Studnemund,
although this version has been changed somewhat:
- reference counting on ifaddrs isn't as complete as Bill's original
  work was.  This is hard to get right, and we should attack one
  protocol at a time.
- This doesn't do reference counting or dynamic allocation of ifnets yet.
- This version introduces a new PRU -- PRU_PURGEADDR, which is used to
  purge an ifaddr from a protocol.  The old method Bill used didn't work
  on all protocols, and it only worked on some because it was Very Lucky.

This mostly works ... i.e. works for my USB Ethernet, except for a dangling
ifaddr reference left by the IPv6 code; have not yet tracked this down.

itojun 118d2b1d4f IPv6 kernel code, based on KAME/NetBSD 1.4, SNAP kit 19990628.
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.

- sys/kern: do not assume single mbuf, accept chained mbuf on passing
  data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
  package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
  file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen

In my understanding no code here is subject to export control so it
should be safe.
