7e760e148a Originally when DEVFS was added, a global variable "devfs_present"
was used to control code which were conditional on DEVFS' precense
since this avoided the need for large-scale source pollution with
#include "opt_geom.h"

Now that we approach making DEVFS standard, replace these tests
with an #ifdef to facilitate mechanical removal once DEVFS becomes
non-optional.

9967cafc49 Correct mbuf packet header propagation. Previously, packet headers
were sometimes propagated using M_COPY_PKTHDR which actually did
something between a "move" and a  "copy" operation.  This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain.  This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.

These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block.  This
introduces an incompatibility with openbsd which we may want to revisit.

Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them.  We may want to support this;
for now we watch for it with an assert.

Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

03a585553a Oops, I misread the purpose of the NULL check in EH_RESTORE() in
revision 1.62. It was checking for M_PREPEND() failing, not for the
case of a NULL mbuf pointer being supplied to the macro. Back out
that revision, and fix the NULL dereference by not calling EH_RESTORE()
in the case where the mbuf pointer is NULL because the firewall
rejected the packet.

36fea5de60 rn_walktree*() compute the next leaf before applying a function
to current leaves because function may vanish the current node.

If parent RTA_GENMASK route has a clone (a "cloning clone"), an
rn_walktree_from() starting from parent will cause another walk
starting from clone.  If a function is either rt_fixdelete() or
rt_fixchange(), this recursive walk may vanish the leaf that is
remembered by an outer walk (the "next leaf" above), panicing a
system when it resumes with an outer walk.

The following script paniced my single-user mode booted system:

: sysctl net.inet.ip.forwarding=1
: ipfw add 1 allow ip from any to any
: ifconfig lo0 127.1
: route add -net 10 -genmask 255.255.255.0 127.1
: telnet 10.1			# rt_fixchange() panic
: telnet 10.2
: telnet 10.1
: route delete -net 10		# rt_fixdelete() panic

For the time being, avoid these races by disallowing recursive
walks in rt_fixchange() and rt_fixdelete().

Also, make a slight optimization in the rtrequest(RTM_RESOLVE)
case: there is no reason to call rt_fixchange() in this case.

fe6fb873dc Under some circumstances, the loopback interface will allocate a new
mbuf for a packet looping back to provide alignment guarantees for
KAME.  Unfortunately, this code performs a direct copy of the header
rather than using a header copying primitive (largely because we have
sucky header copying primitives).  This results in a multiple free
of the MAC label in the header when the same label data is freed
twice when the two mbufs with that header are freed.  As a temporary
work-around, clear the initialized flag on the label to prevent the
duplicate free, which prevents panics on large unaligned loopback
IP and IPv6 data.  The real fix is to improve and make use of proper
packet header copying routines here.

bbb4330b61 Massive cleanup of the ip_mroute code.
No functional changes, but:

  + the mrouting module now should behave the same as the compiled-in
    version (it did not before, some of the rsvp code was not loaded
    properly);
  + netinet/ip_mroute.c is now truly optional;
  + removed some redundant/unused code;
  + changed many instances of '0' to NULL and INADDR_ANY as appropriate;
  + removed several static variables to make the code more SMP-friendly;
  + fixed some minor bugs in the mrouting code (mostly, incorrect return
    values from functions).

This commit is also a prerequisite to the addition of support for PIM,
which i would like to put in before DP2 (it does not change any of
the existing APIs, anyways).

Note, in the process we found out that some device drivers fail to
properly handle changes in IFF_ALLMULTI, leading to interesting
behaviour when a multicast router is started. This bug is not
corrected by this commit, and will be fixed with a separate commit.

Detailed changes:
--------------------
netinet/ip_mroute.c     all the above.
conf/files              make ip_mroute.c optional
net/route.c             fix mrt_ioctl hook
netinet/ip_input.c      fix ip_mforward hook, move rsvp_input() here
                        together with other rsvp code, and a couple
                        of indentation fixes.
netinet/ip_output.c     fix ip_mforward and ip_mcast_src hooks
netinet/ip_var.h        rsvp function hooks
netinet/raw_ip.c        hooks for mrouting and rsvp functions, plus
                        interface cleanup.
netinet/ip_mroute.h     remove an unused and optional field from a struct

6b459e4956 When packets pass in and out of six-to-four (STF) tunnels, perform
labeling checks and operations as with other network interfaces.
Eventually, if it proves desirable, we might want to offer special
casing of this or other tunnel interfaces where we have an existing
label of interest, rather than treating it as though it's an
entirely fresh mbuf in the incoming/outgoing encapsulation directions.

4141b621ac When a packet is sent via a FDDI interface, perform appropriate MAC
transmission checks; when it is received, label the packet appropriately.
Although we don't have a local FDDI setup to test this with, the
labeling and checks are identical to other interface classes.

9476111d3a When a packet is destined for delivery via an ATM medium, perform
appropriate interface transmission checks and delivery labeling.  While
we don't have a local ATM configuration, this code is almost identical
to all other interface classes.

9426aedf7f - after gif_set_tunnel(), psrc/pdst may be null. set IFF_RUNNING accordingly.
- set IFF_UP on SIOCSIFADDR.  be consistent with others.
- set if_addrlen explicitly (just in case)
- multi destination mode is long gone.
- missing break statement
- add gif_set_tunnel(), so that we can set tunnel address from within the
  kernel at ease.
- encap_attach/detach dynamically on ioctls
- move encap_attach() to dedicated function in in*_gif.c

5d84645305 Replace aux mbufs with packet tags:
o instead of a list of mbufs use a list of m_tag structures a la openbsd
o for netgraph et. al. extend the stock openbsd m_tag to include a 32-bit
  ABI/module number cookie
o for openbsd compatibility define a well-known cookie MTAG_ABI_COMPAT and
  use this in defining openbsd-compatible m_tag_find and m_tag_get routines
o rewrite KAME use of aux mbufs in terms of packet tags
o eliminate the most heavily used aux mbufs by adding an additional struct
  inpcb parameter to ip_output and ip6_output to allow the IPsec code to
  locate the security policy to apply to outbound packets
o bump __FreeBSD_version so code can be conditionalized
o fixup ipfilter's call to ip_output based on __FreeBSD_version

91e97a8266 In an SMP environment post-Giant it is no longer safe to blindly
dereference the struct sigio pointer without any locking.  Change
fgetown() to take a reference to the pointer instead of a copy of the
pointer and call SIGIO_LOCK() before copying the pointer and
dereferencing it.
