ifconfig/Makefile: Makefile.inc -> Makefile.common in comment, NFC

I forgot to update this comment when I renamed Makefile.inc to .common.

branches: 1.61.16;
user librumpres

Cosmetic changes. No functional changes.

Factor out a common part in Makefile's of ifconfig and x_ifconfig.

Rename sbin/ifconfig/Makefile.inc to Makefile.common; the former can
potentially conflict with bsd.subdir.mk.

Remove ifconfig hack on m68000. I've confirmed that the problem has already
gone with TME.

branches: 1.56.2; 1.56.4;
Fix rump.ifconfig shows host's interface names in link local addresses

all of this should be looked at closer, but some of them are not
very trivial.

Convert from the .ifdef RUMP_ACTION stuff to RUMPPRG.

Need getifaddrs() for the rump client since it executes sysctl(2)

Update RUMP_ACTION to use the newstyle rump client.

Apparently, -g belongs in the DBG variable, not in CFLAGS. Make it so
on a line that is commented-out in this makefile.

- no space needed between -I and dir per gcc(1)
- it's still better to use ${NETBSDSRCDIR} per other existing Makefiles

Add comments that Makefile.inc should have shared stuff with
src/distrib/utils/x_ifconfig for install media.

Move the addition of pfsync.c from Makefile.inc to Makefile,
so that this part doesn't get included in install media versions
of ifconfig, as per comments on source-changes@ from Izumi Tsutsui.
Also re-instate the use of ${.CURDIR} when setting up the include path.

If RUMP_ACTION, treat close() as a rump syscall.

Add compile mode which executes rump system calls. This is useful
when figuring out Where In The Kernel Is Carmen Sandiego's ioctl
for an ifconfig command line, since we can simply single-step into
the kernel.

Activated by "make RUMP_ACTION=1". No changes to normal case.

Enable WARNS=4 by default except for:
dump dump_lfs fsck_ffs fsck_lfs fsdb mount_smbfs
newfs_ext2fs newfs_lfs resize_lfs setkey

Let us add/remove features from ifconfig, such as support for
various address families (inet, inet6, iso, atalk) and protocols
(802.11, 802.3ad, CARP), simply by trimming the list of sources in
the Makefile. This helps one customize ifconfig for an embedded
device or for install media, and it eliminates a lot of grotty
#ifdef'age. Now, the ifconfig syntax and semantics are finalized
at run-time using the constructor routines in each address-family/protocol
module.

(In principle, ifconfig could load virtually all of its syntax from
shared objects.)

Extract a lot of common code into subroutines, in order to shrink
the ifconfig binary a bit. Make all of the address families share
code for address addition/replacement/removal, and delete "legacy"
code for manipulating addresses. That may have broken atalk and
iso, despite my best efforts.

Extract an include file, Makefile.inc, containing the make-fu that
both ifconfig and x_ifconfig share.

Sprinkle static. Change some int's to bool's. Constify.

Add RCS Ids to carp.c and env.c. Move media code to a new file,
media.c. Delete several unneeded header files.

Set, reset, and display the IEEE 802.11 attribute, 'dot11RTSThreshold'.

Bug fix: do not require both a interface address and a destination
address for point-to-point interfaces, but accept a interface
address by itself.

Per discussion at
<http://mail-index.netbsd.org/tech-net/2008/04/08/msg000371.html>,
let us add, delete, and activate link-layer addresses with ifconfig:

# ifconfig sip0 link 02:00:00:00:00:01 [add address]
# ifconfig sip0 link 02:00:00:00:00:02 [add address]
# ifconfig sip0 link 02:00:00:00:00:02 active [activate address]
# ifconfig sip0 link 02:00:00:00:00:01 delete [remove address]

Don't use -pedantic, it stops af_atalk.c and af_iso.c from building
if INET_ONLY is #defined.

Remove CPPFLAGS that are redundant when WARNS=4.

branches: 1.34.2;
Add WARNS=4 and a dependency on ${LIBPROP}.

Take out my CFLAGS settings for debugging.

Overhaul ifconfig. Use fewer global variables. Take a leap toward

In the new architecture, a directed graph of argument-matching
objects (match objects) expresses the set of feasible ifconfig
statements. Match objects are labelled by subroutines that provide
the statement semantics.

is@ pointed out that I set the phase and range of a sockaddr_at
without subsequently doing anything with it, so commit_address()
works with an address with phase == 0. phase == 0 is not allowed,
hence

random84# ifconfig nfe0 atalk 3.14
ifconfig: SIOCAIFADDR: Invalid argument

Solution: copy the new sockaddr_at to a temporary input environment,
and pass that environment to commit_address(). I may as well copy
the new sockaddr_at to the output environment, while I am at it.

Solution suggested by <uwe>

Sponsored by <The NetBSD Foundation>

branches: 1.24.12;

Return to printing explicit "netmask 0x...." in the case that the
mask set is non-contiguous. We don't prohibit setting such things
(even if they are basically useless) so they can be set by accident.
ifconfig ifN 10.0.0.1 netmask 225.0.0.0
produced
ifN .. inet 10.0.0.1/8
with the previous form (since 225 is 0xE1), now it produces
ifN ... inet 10.0.0.1 netmask 0xe1000000

If the "netmask" form ever appears in ifconfig output, it (now)
means that the netmask is non-contig, which should make that case
obvious (whther intended, or set by accident)

Modernise the output for the address to address/prefix instead
of differring outputs for INET and INET6.
The hex string of the INET netmask was particulary hard to read.

Remove the alias keyword from ifconfig output as it serves no purpose.

ifaddrs has more data than just the address.
Use it instead of making pointless ioctl calls.

Make ifconfig(8) set and display preference numbers for IPv6
addresses. Make the kernel support SIOC[SG]IFADDRPREF for IPv6
interface addresses.

In in6ifa_ifpforlinklocal(), consult preference numbers before
making an otherwise arbitrary choice of in6_ifaddr. Otherwise,
preference numbers are *not* consulted by the kernel, but that will
be rather easy for somebody with a little bit of free time to fix.

Please note that setting the preference number for a link-local
IPv6 address does not work right, yet, but that ought to be fixed
soon.

In support of the changes above,

1 Add a method to struct domain for "externalizing" a sockaddr, and
provide an implementation for IPv6. Expect more work in this area: it
may be more proper to say that the IPv6 implementation "internalizes"
a sockaddr. Add sockaddr_externalize().

2 Add a subroutine, sofamily(), that returns a struct socket's address
family or AF_UNSPEC.

3 Make a lot of IPv4-specific code generic, and move it from
sys/netinet/ to sys/net/ for re-use by IPv6 parts of the kernel and
ifconfig(8).

Use getnameinfo(3) instead of inet_ntoa(3) to convert IPv4 addresses
to names.

Make ifconfig(8) set and display preference numbers for IPv6
addresses. Make the kernel support SIOC[SG]IFADDRPREF for IPv6
interface addresses.

In in6ifa_ifpforlinklocal(), consult preference numbers before
making an otherwise arbitrary choice of in6_ifaddr. Otherwise,
preference numbers are *not* consulted by the kernel, but that will
be rather easy for somebody with a little bit of free time to fix.

Please note that setting the preference number for a link-local
IPv6 address does not work right, yet, but that ought to be fixed
soon.

In support of the changes above,

1 Add a method to struct domain for "externalizing" a sockaddr, and
provide an implementation for IPv6. Expect more work in this area: it
may be more proper to say that the IPv6 implementation "internalizes"
a sockaddr. Add sockaddr_externalize().

2 Add a subroutine, sofamily(), that returns a struct socket's address
family or AF_UNSPEC.

3 Make a lot of IPv4-specific code generic, and move it from
sys/netinet/ to sys/net/ for re-use by IPv6 parts of the kernel and
ifconfig(8).

Add option -N. -N is just the opposite of option -n in netstat(8)
or route(8): it tells ifconfig(8) to try to resolve numbers to
hosts and service names.

This default ifconfig behavior stays the same as it always was.

Only describe flags -L and -m in the usage if they are available.
That helps me get rid of some conditional compilation (INET6) in
ifconfig.

Let each protocol/feature-module print its own usage, so that the
ifconfig usage reflects the modules that are actually compiled-in.

Write usage information for carp(4) options.

Let us add/remove features from ifconfig, such as support for
various address families (inet, inet6, iso, atalk) and protocols
(802.11, 802.3ad, CARP), simply by trimming the list of sources in
the Makefile. This helps one customize ifconfig for an embedded
device or for install media, and it eliminates a lot of grotty
#ifdef'age. Now, the ifconfig syntax and semantics are finalized
at run-time using the constructor routines in each address-family/protocol
module.

(In principle, ifconfig could load virtually all of its syntax from
shared objects.)

Extract a lot of common code into subroutines, in order to shrink
the ifconfig binary a bit. Make all of the address families share
code for address addition/replacement/removal, and delete "legacy"
code for manipulating addresses. That may have broken atalk and
iso, despite my best efforts.

Extract an include file, Makefile.inc, containing the make-fu that
both ifconfig and x_ifconfig share.

Sprinkle static. Change some int's to bool's. Constify.

Add RCS Ids to carp.c and env.c. Move media code to a new file,
media.c. Delete several unneeded header files.

Set, reset, and display the IEEE 802.11 attribute, 'dot11RTSThreshold'.

Bug fix: do not require both a interface address and a destination
address for point-to-point interfaces, but accept a interface

Retire in6_addreq and in6_ridreq, which we do not use in the
commit_address() regime.

Initialize IPv6 addresses and ifreqs with more rigor. Fixes this

ifconfig: SIOCAIFADDR_IN6: Invalid argument
# ifconfig sip0 inet6 fdb4:542d:dc11:ec20::1 prefixlen 64

Get rid of sec2str() altogether.

In in6_alias(), instead of repeating the memset()/estrlcpy()/sockaddr_in6
assignment-dance, copy creq to ifr6 before each ioctl().

Delete unused array sin6tab[]. Delete unnecessary casts.

Delete dead code in sec2str().

Retire some code that in6_commit_address() replaces.

Let the address family modules zero initialize their own ifreqs,
instead of zeroing them in commit_address().

Switch to in6_commit_address() from in6_getprefix() and in6_getaddr().

Temporarily add some debugging code to setia6eui64_impl().

from ifconfig.c to parse.h for reuse.

Fix a bug that I introduced in rev 1.88, where the default IPv6

Let us add/remove features from ifconfig, such as support for
various address families (inet, inet6, iso, atalk) and protocols
(802.11, 802.3ad, CARP), simply by trimming the list of sources in
the Makefile. This helps one customize ifconfig for an embedded
device or for install media, and it eliminates a lot of grotty
#ifdef'age. Now, the ifconfig syntax and semantics are finalized
at run-time using the constructor routines in each address-family/protocol
module.

(In principle, ifconfig could load virtually all of its syntax from
shared objects.)

Extract a lot of common code into subroutines, in order to shrink
the ifconfig binary a bit. Make all of the address families share
code for address addition/replacement/removal, and delete "legacy"
code for manipulating addresses. That may have broken atalk and
iso, despite my best efforts.

Implement VLAN hardware filter function(ETHERCAP_VLAN_HWFILTER).
First proposed by jmcneill in 2017 and modified by me.

How to use:

- Set callback function:

ether_set_vlan_cb(struct ethercom *, ether_vlancb_t)

- Callback. This function is called when a vlan is attached/detached to the
parent interface:

int (*ether_vlancb_t)(struct ethercom *ec, uint16_t vlanid, bool set);

- ifconfig(8)

ifconfig ixg0 [-]vlan-hwfilter

Note that ETHERCAP_VLAN_HWFILTER is set by default on ixg(4) because
the PF driver usually enable "all block" filter by default.

KNF. No functional change.

Add "ifconfig [-]vlan-hwtagging" to enable/disable VLAN hardware tagging
offload function. It's useful to see Ethernet frame's VLAN tag by
disabling with "ifconfig fooX -vlan-hwtagging" and "tcpdump -e -i fooX".

improved modularity and extensibility.

In the new architecture, a directed graph of argument-matching
objects (match objects) expresses the set of feasible ifconfig
statements. Match objects are labelled by subroutines that provide
the statement semantics.

Many IPv4, IPv6, 802.11, tunnel, and media configurations have been
tested.

AppleTalk, ISO, carp(4), agr(4), and vlan(4) configuration need

Add a mode to gre(4) that sends GRE tunnel packets in UDP datagrams.
Fix MOBILE encapsulation. Add many debugging printfs (mainly

capability to setup UDP tunnels to ifconfig. Update documentation.

In UDP mode, gre(4) puts a GRE header onto transmitted packets,
and hands them to a UDP socket for transmission. That is, the
encapsulation looks like this: IP+UDP+GRE+encapsulated packet.

There are two ways to set up a UDP tunnel. One way is to tell the
source and destination IP+port to gre(4), and let gre(4) create
the socket. The other way to create a UDP tunnel is for userland
to "delegate" a UDP socket to the kernel.

Drop arguments of .Os.

Implement support for IP/TCP/UDP checksum offloading provided by
network interfaces. This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us. In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software. This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off". It is
enabled with ifconfig(8). See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.

ifconfig: go back to using direct ioctls rather than data from getifaddrs

AF_LINK may not be the first address returned for the interface.
Technically, it *might* not even exist on the interface even though
other families do.
This is likely a driver bug if this really is the case though.

As such it's just easier to use direct ioctls rather than thump around
getifaddrs results. As it stands, the code makes a lot of getifaddrs
calls anyway, so an extra ioctl or two won't break the bank.

ifconfig: Just look at if_data->ifi_link_state for carrier

It should be the sole source of truth.
if_data is also carried in ifa_data from getifaddrs(3) which saves
more ioctl calls.

ifconfig: We already have struct if_data in ifa_data.

So let's not bother with an ioctl we don't need.

ifconfig: test cases want LINK_STATE_UNKNOWN to be treated as up.

ifconfig: teach carrier test about ifi_link_state from SIOCGIFDATA

Because not all interfaces support media.

ifconfig: Report link state even if media is not supported

For AF_LINK addrs from getifaddrs(2), ifa_data is struct if_data.
This in turn holds ifi_link_state which we can use to report
link status if the interface does not support media where it's normally
reported.

Based on OpenBSD.
