dyoung 2fc102750d Use ifreq_setaddr(), ifreq_getaddr(), sockaddr_in_init(), and
sockaddr_copy().  Constify.  Compare pointers with NULL, not 0.
Don't "test truth" of pointers, but compare with NULL.

christos 53524e44ef Kill caddr_t; there will be some MI fallout, but it will be fixed shortly. 2007-03-04 05:59:00 +00:00
dyoung 5493f188c7 KNF: de-__P, bzero -> memset, bcmp -> memcmp. Remove extraneous
parentheses in return statements.

Cosmetic: don't open-code TAILQ_FOREACH().

Cosmetic: change types of variables to avoid oodles of casts: in
   in6_src.c, avoid casts by changing several route_in6 pointers
   to struct route pointers.  Remove unnecessary casts to caddr_t
   elsewhere.

Pave the way for eliminating address family-specific route caches:
   soon, struct route will not embed a sockaddr, but it will hold
   a reference to an external sockaddr, instead.  We will set the
   destination sockaddr using rtcache_setdst().  (I created a stub
   for it, but it isn't used anywhere, yet.)  rtcache_free() will
   free the sockaddr.  I have extracted from rtcache_free() a helper
   subroutine, rtcache_clear().  rtcache_clear() will "forget" a
   cached route, but it will not forget the destination by releasing
   the sockaddr.  I use rtcache_clear() instead of rtcache_free()
   in rtcache_update(), because rtcache_update() is not supposed
   to forget the destination.

Constify:

   1 Introduce const accessor for route->ro_dst, rtcache_getdst().

   2 Constify the 'dst' argument to ifnet->if_output().  This
     led me to constify a lot of code called by output routines.

   3 Constify the sockaddr argument to protosw->pr_ctlinput.  This
     led me to constify a lot of code called by ctlinput routines.

   4 Introduce const macros for converting from a generic sockaddr
     to family-specific sockaddrs, e.g., sockaddr_in: satocsin6,
     satocsin, et cetera.

rpaulo a0814a3043 Add full support for IPv6 tunnels. From DEGROOTE Arnaud in PR 32944.
The PR submitter and the PR handler were unable to test this code
using Teredo userland clients such as Miredo. However, the PR handler
dumped and analyzed some of the packets produced by Miredo and they
seemed fine.
(On a side note: I was unable to setup Teredo in Windows XP and the
problem seemed similar to what I currently see in NetBSD: lack of
replies from the Teredo relay).

pk 454a5a1188 Fix locking issues noticed by Tom Ivar Helbekkmo on tech-net:
* always acquire the device instance lock at splnet()
	* missing unlocks in various places

Also, since this driver allows its device instances manipulated by two
independent subsystems (character device & interface clone create/destroy),
be careful not to rip away instance data in a clone destroy request if the
instance is still opened as a character device.

jdolecek 7cea8a1389 cleanup & uniform descriptor owner handling:
* introduce fsetown(), fgetown(), fownsignal() - this sets/retrieves/signals
  the owner of descriptor, according to appropriate sematics
  of TIOCSPGRP/FIOSETOWN/SIOCSPGRP/TIOCGPGRP/FIOGETOWN/SIOCGPGRP ioctl; use
  these routines instead of custom code where appropriate
* make every place handling TIOCSPGRP/TIOCGPGRP handle also FIOSETOWN/FIOGETOWN
  properly, and remove the translation of FIO[SG]OWN to TIOC[SG]PGRP
  in sys_ioctl() & sys_fcntl()
* also remove the socket-specific hack in sys_ioctl()/sys_fcntl() and
  pass the ioctls down to soo_ioctl() as any other ioctl

darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

jdolecek e0cc03a09b merge kqueue branch into -current
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk.
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

atatat 6675196afb Make tun interfaces perform auto-creation. This means that if a
program opens /dev/tun# and tun# has not been SIOCIFCREATE'd already,
it will be SIOCIFCREATE'd automatically.  FreeBSD's tun interfaces
behave in a somewhat similar fashion.
