95f9af9926 Apply patch from PR 23990 by Greg Troxel (s/AF_DLI/AF_LINK/ in a comment):
<net/if_dl.h> defines struct sockaddr_dl.  On the line defining member
"sdl_family" (which overlaps "sa_family" in struct sockaddr), the
comment says AF_DLI.

But,
1) AF_DLI is said to be a DEC Direct data link interface
   (sys/socket.h)
2) The kernel actually sends sockaddr_dl structs with AF_LINK.

fbbeedbe63 PR/27286: Tom Ivar Helbekkmo: Allow RTM_GET to work with RTA_IFA|RTA_IFP set.
Quiting Tom: The problem is the special case of an RTM_GET message
that wants interface information included in the response, and
therefore include the RTA_IFA or RTA_IFP (or both) flags in the
bitmask that says what addresses are supplied in the message.  For
the RTM_GET message, it doesn't make sense to supply addresses
other than the one you're asking about, so those two other bits
are, in that specific case, overloaded with this meaning.

There is code in sys/net/rtsock.c to handle the case, but at some
time, extra sanity checking of the received message was added, that
failed to take this possibility into account.

The patch, is needed for the Asterisk software PBX to work properly
when it has multiple interfaces active: it needs to ask the kernel
for the IP address of the interface that will be used to communicate
with a given host.

7cd90d66b7 If the parent interface is not IFF_RUNNING, do not call its start function.
This prevent a variety of fun panics, and therefore fixes PR 12932, PR 17561,
and PR 18376...

XXX
...however this is most definitely a hack.  The real problem here is that there
is no callback to notify a "client" interface like vlan when a "parent"
interface's status changes, and therefore the vlan interface is always
IFF_RUNNING.  This allows packets to be queued on vlan interface at any time.
We can't simply leave the packets on the vlan interface, either, because there
is no callback to dequeue them.  And last, since it's always IFF_RUNNING, if
we just *toss* the packets, we lose gratuitous ARPs and DAD packets.

"This needs work," but at least it no longer bleeds.

887b782b0b Initial commit of a port of the FreeBSD implementation of RFC 2385
(MD5 signatures for TCP, as used with BGP).  Credit for original
FreeBSD code goes to Bruce M. Simpson, with FreeBSD sponsorship
credited to sentex.net.  Shortening of the setsockopt() name
attributed to Vincent Jardin.

This commit is a minimal, working version of the FreeBSD code, as
MFC'ed to FreeBSD-4. It has received minimal testing with a ttcp
modified to set the TCP-MD5 option; BMS's additions to tcpdump-current
(tcpdump -M) confirm that the MD5 signatures are correct.  Committed
as-is for further testing between a NetBSD BGP speaker (e.g., quagga)
and industry-standard BGP speakers (e.g., Cisco, Juniper).


NOTE: This version has two potential flaws. First, I do see any code
that verifies recieved TCP-MD5 signatures.  Second, the TCP-MD5
options are internally padded and assumed to be 32-bit aligned. A more
space-efficient scheme is to pack all TCP options densely (and
possibly unaligned) into the TCP header ; then do one final padding to
a 4-byte boundary.  Pre-existing comments note that accounting for
TCP-option space when we add SACK is yet to be done. For now, I'm
punting on that; we can solve it properly, in a way that will handle
SACK blocks, as a separate exercise.

In case a pullup to NetBSD-2 is requested, this adds sys/netipsec/xform_tcp.c
,and modifies:

b0a71dcaf5 Update bpf buffer parameters, as per recent discussion on tech-net.
Increase the default bpf buffer size used by naive apps that don't do
BIOCSBLEN, from 8k to 32k.  The former value of 8192 is too small to
hold a normal jumbo Ethernet frame (circa 9k), 16k is a little small
for Large-jumbo (~16k) frames supported by newer gigabit
Ethernet/10Gbe, so (somewhat arbitrarily) increase the default to 32k.

Increase the upper limit to which BIOSBLEN can raise bpf buffer-size
drastically, to 1 Mbyte.  State-of-the-art for packet capture circa
1999 was around 256k; savvy NetBSD developers now use 1 Mbyte.
Note that libpcap has been updated to do binary-search on BIOCSBLEN
values up to 1 Mbyte.

Work is in progress to make both values sysctl'able. Source comments
note that consensus on tech-net is that we should find some heuristic
to set the boot-time default values dynamically, based on system memory.

removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

fa24e6f3f8 Add m_tag_delete_nonpesrsistent(), for deleting all packet tags on
mbuf chains which are recycled (e.g., ICMP reflection, loopback
interface).  A consensus was reached that such recycled packets should
behave (more-or-less) the same way if a new chain had been allocated
and the contents copied to that chain.

Some packet tags may in future be marked as "persistent" (e.g., for
mandatory access controls) and should persist across such deletion.
NetBSD as yet hos no persistent tags, so m_tag_delete_nonpersistent()
just deletes all tags. This should not be relied upon.

14332cf998 fix interface address list traversal in if_detach():
The code was assuming that interface addresses are removed one-by-one.
With IPv6 and multicasts, removal of one address can remove other

42091f2362 From OpenBSD 1.33-1.34:
When using bpf(4) in immediate mode, and using kevent(2) to receive
notification of packet arrival, the usermode application isn't notified
until a second packet arrives.

This is because KNOTE() calls filt_bpfread() before bd_slen has been
updated with the newly arrived packet length, so it looks like there
is no data there.

Moving the bpf_wakeup() call for immediate mode to after bd_slen is set
fixes it.

4be7a2dcf3 Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
  can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
  various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
  !defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them.  In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

0ad9e0dccc Host AP power saving support. The Host AP notices that the power
saving bit is set in incoming frames from a station, and buffers the
outgoing frames for the station until they are polled for.  This
requires support in the driver to set a bit in the TIM bitmap sent
during 802.11 beacons.

So far, support for power saving in Host AP mode is only available
for the PRISM2 chipset.

013798abf2 Make promiscous mode work on vlans: introduce a new link-layer m_flag
M_PROMISC. In ether_input(), flag packets comming from an interface in
promiscous mode which are not for us M_PROMISC instead of droping them.
Drop M_PROMISC packets which are not passed to vlan_input(). M_PROMISC
packets passed to vlan_input() will be looped back to ether_input()
the M_PROMISC flag will be handled appropriately.
Clear M_PROMISC before giving the packet to bridge, as bridge has its own
checks for local MAC addresses.
This also makes bridges on vlan working.

4a3c894eef Fix 2 bugs:
- initialise stp when the bridge is turned up, without this stp will keep
  all interfaces disabled in a sequence like:
  brconfig bridge0 add if0 add if1 stp if0 stp if1 up
- s/BRDGSPRI/BRDGSIFPRIO in brconfig.c:cmd_ifpriority()

add a command (ifpathcost) to change the stp path cost of the STP path cost of
an interface. Display the interface path cost with the others STP parameters.
