62d6ce3af2 I got another batch of suggestions for cosmetic changes from bde. 1998-11-11 10:56:07 +00:00

831d27a9f5 Installed the second patch attached to kern/7899 with some changes suggested
by bde, a few other tweaks to get the patch to apply cleanly again and
some improvements to the comments.

This change closes some fairly minor security holes associated with
F_SETOWN, fixes a few bugs, and removes some limitations that F_SETOWN
had on tty devices.  For more details, see the description on the PR.

Because this patch increases the size of the proc and pgrp structures,
it is necessary to re-install the includes and recompile libkvm,
the vinum lkm, fstat, gcore, gdb, ipfilter, ps, top, and w.

5158516f4e In an attempt to reduce the huge number of differences between the
FreeBSD repository version of this file and the isdn4bsd version,
adopt those changes from the i4b version that make this file
BSD-version independent.  I attempted to avoid uglifying this file too
much, thus deviated a little from the i4b version (and hope they will
adopt the changes, too).

The diffs mostly concentrate on:

. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
  unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in
  Net/OpenBSD (for loopback detection ad CHAP challenges -- i
  assume at least OpenBSD could also benefit from random(), but that's
  the way i've got this file)
. interface address list elements are named a little differently
  between FreeBSD and Net/OpenBSD

I attempted to segregate those compat fixes from other code fixes and
enhancements.

c7323482f4 One-liner: add a call to the underlying device driver's SIOCDELMULTI
ioctl() routine at the end of if_delmulti() so that interfaces with
hardware multicast filtering can update their filters in a timely
manner.

If the interface doesn't support hardware multicast filtering, then
reception of multicast frames is done using 'promiscious mode' or
'capture all multicast frames' mode and software filtering in the
kernel. In this case, it doesn't matter if if_delmulti() ever does
an SCIODELMULTI on the interface or not: if MULTICAST support is
enabled, then we join the 'all hosts' group when the interface is
configured, and remain in it until the interface is brought down.
Without hardware filtering, joining one group means joining all
groups, so it makes no difference if we call the SIOCDELMULTI
routine.

If the interface does support hardware multicast filtering, then
by not reprogramming the hardware filter in if_delmulti(), we have
to wait until somebody calls if_setmulti(), during which time the
interface is receiving frames for multicast groups in which we are
no longer interested.

4f53e3cc7a update ATM driver. (base version: midway.c 1.67 --> 1.68)
several new features are added:
	- support vc/vp shaping
	- support pvc shadow interface

code cleanup:
	- remove WMAYBE related code.  ENI WMAYBE DMA doen't work.
	- remove updating if_lastchange for every packet.
	- BPF related code is moved to midway.c as it should be.
	  (bpfwrite should work if atm_pseudohdr and LLC/SNAP are
	  prepended.)
	- BPF link type is changed to DLT_ATM_RFC1483.
	  BPF now understands only LLC/SNAP!! (because bpf can't
	  handle variable link header length.)
	  It is recommended to use LLC/SNAP instead of NULL
	  encapsulation for various reasons.  (BPF, IPv6,
	  interoperability, etc.)

the code has been used for months in ALTQ and KAME IPv6.

OKed by phk long time ago.

a23d65bfc8 Cast pointers to uintptr_t/intptr_t instead of to u_long/long,
respectively.  Most of the longs should probably have been
u_longs, but this changes is just to prevent warnings about
casts between pointers and integers of different sizes, not
to fix poorly chosen types.

c086febef5 Don't attempt to optimize the space allocated for bpf headers if
sizeof(struct bpf_hdr) > 20.  20 is normal on 32-bit systems with
32-bit alignment, but we still assume that the last 2 bytes of the
struct are unnecessary padding on such systems.  On systems with
64-bit longs, struct timeval is bloated to 16 bytes, so bpf headers
certainly don't fit in 18 bytes.

ed7509ace4 Go through the loopback code with a broom..
Remove lots'o'hacks.
looutput is now static.

Other callers who want to use loopback to allow shortcutting
should call the special entrypoint for this, if_simloop(), which is
specifically designed for this purpose. Using looutput for this purpose
was problematic, particularly with bpf and trying to keep track
of whether one should be using the charateristics of the loopback interface
or the interface (e.g. if_ethersubr.c) that was requesting the loopback.
There was a whole class of errors due to this mis-use each of which had
hacks to cover them up.

Consists largly of hack removal :-)

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

1f91d8c563 Added fast IP forwarding code by Matt Thomas <matt@3am-software.com> via
NetBSD, ported to FreeBSD by Pierre Beyssac <pb@fasterix.freenix.org> and
minorly tweaked by me.
This is a standard part of FreeBSD, but must be enabled with:
"sysctl -w net.inet.ip.fastforwarding=1" ...and of course forwarding must
also be enabled. This should probably be modified to use the zone
allocator for speed and space efficiency. The current algorithm also
appears to lose if the number of active paths exceeds IPFLOW_MAX (256),
in which case it wastes lots of time trying to figure out which cache
entry to drop.
