Retire struct sockaddr_inarp.

Since ARP and routing are separated, "proxy only" entries
don't have any meaning, thus we don't need additional field
in sockaddr to pass SIN_PROXY flag.

New kernel is binary compatible with old tools, since sizes
of sockaddr_inarp and sockaddr_in match, and sa_family are
filled with same value.

The structure declaration is left for compatibility with
third party software, but in tree code no longer use it.

Per letter dated July 22, 1999 remove 3rd clause of Berkeley derived software
(with permission of addtional copyright holders where appropriate)

While walking over the list of interfaces obtained from getifaddrs(3),
rarpd clobbered any AF_INET information already configured for a given
interface name, so interfaces with more than one IP address made rarpd
listen only for the last address out of all IP aliases.

I changed this, so that AF_LINK information is always collected first
(to ensure the interface name gets its link-layer address associated),
but while looking for AF_INET addresses, the configuration is cloned
if there has already been one IP address seen for that interface name.

Thus, rarpd now effectively listens on all subnets.

Lower WARNS to 3 so that this still compiles on non x86 architectures.

Huge cleanup of the rarpd(8) code :
- Use getifaddrs() instead of rolling our own buggy one. Previously,
rarpd(8) would fail to see some interfaces because of a hardcoded limit.
It now successfully sees any interface in the system, and this also makes
the code _much_ simpler.
- Replace strncpy() calls with strlcpy() calls. Some uses of strncpy()
were bogus ; the code wasn't ensuring that the string was NUL terminated.
- Don't try to guard about select() FD_* macros being undefined.
- Use IF_NAMESIZE and ETHER_ADDR_LEN macros where appropriate.
- Add static keywords to function definitions for consistency, since
the prototypes have it (I wonder why GCC didn't complain about this).
- Remove compat code for very old BSD versions and SunOS.
- Remove code for systems not having the dirent.h header.
- The code is now WARNS=5 clean so mark it as such.

- spell u_int consistently (never use "unsigned").

Sync usage string with reality: removed -n, added -s.

Fix bug in rarpd:

Explanation of the bug: when processing its first request, rarpd
opens a routing socket to send requests to the arp table. It keeps
that socket open afterwards, while waiting for new RARP requests.

Meanwhile, the data received on the routing socket fill up until
they are about 8Kbytes in size. Any additional data is lost.

When rarpd receives its next RARP request, it tries to access the
ARP table via a routing socket call, then waits for the answer to
its own request. This answer is lost because the received data is
already filled: when looking for the reply, rarpd receives only
8kbytes worth of data, then loops waiting forever.

Someone please test it on -STABLE and commit it. We can close the PR
when testing on STABLE is done.

Logging cleanups (including logging the requestor's MAC address instead

Although I got rarpd to work, it was largely through kludgery. Bill
Fenner was kind enough to point out the error of my ways. This incorporates
diffs from him which:

- Keep everything in network order.
- Log the booted ether & ip address, instead of my address on that net
- change several exit()'s to return()'s, so that rarpd continues running
even if it thinks it's in a weird state.

One small tweak by me: in rarp_bootable(), we have to make sure to
construct 'ipname' in host byte order (if we don't, we have to
specify /tftpboot/<remote IP in hex> with <remote IP in hex> in
network byte order, which is confusing).

Also restored use of <dirent.h> rather than <sys/dir.h> as pointed
out by bde.

Also updated the man page so that the -v flag is documented.

With any luck, I won't have to touch this thing again.

Dohw! Left out one important htonl() in update_arptab().

Fix up new rarpd.

This includes the following changes:

- Support for poking ARP entries into the local table is now built
in, so the arptab.c module I hacked together is no longer needed.

- rarp_process() and rarp_reply() now accept a len argument which is
passed down from rarp_loop() which tells rarp_reply() exactly how
long the original RARP frame was. (Usually, it's 60 bytes, which is
the minimum.) Previously, the length was calculated using the sum
of sizeof(struct ether_header) + sizeof(struct ether_arp) (plus the
ethernet frame header, I think). The result was a total packet
length of 42 bytes. Now, rarp_reply() sends out packets that are
the same size as those it recieves (60 bytes). This agrees with the
behavior of rarpd on SunOS (as observed with tcpdump). The unused
extra bytes are zeroed.

This commit was generated by cvs2svn to compensate for changes in r19855,
which included commits to RCS files with non-trunk default branches.

Eliminated includes of the "temporary" backwards compatibility header
<sys/dir.h> in applications. Maintained existing (inadequate) ifdefs
for dir.h vs dirent.h in libdialog, amd and rarpd, but didn't add any
new ones.

It appears that with FreeBSD-current, we need to set the ethernet
frame type in network byte order. The htons() that wasn't needed in
2.1 is now required in 2.2.

Ultimately, this rarpd should be replaced with the more recent one
supplied with the new BPF distribution.

Fix a bunch of spelling errors in a bunch of man pages.

Use daemon() to deamonify ourselves.

Remove trailing whitespace.

Get rid of ether_addr.c: it's been moved to libc. Also add proper
declaration for ether_ntohost(). (Does anyone know what header file
is supposed to contain the declarations for the ether_addr functions?
I can't them in the SunOS includes anywhere.)

Make sure we free() the result returned to us by yp_match().

ether_addr.c:

- Implement ether_hostton()
- Implement ether_aton()
- Modify ether_aton() and ether_ntoa() to match the semantics of the
SunOS versions of these functions.
- Neaten up ether_hostton() and ether_ntohost() a little.
- Get rid of ether_print() since it isn't needed for rarpd and it isn't
documented as a standard ethers(5) function.

rarpd.8:

- Make it clear that the 'ipaddr' that rarpd looks for in /tftpboot
is actually in hexadecimal (as in /tftpboot/803B4032) since those who
are not versed in the black art of system administration are not likely
to know this.

Don't depend on <stdio.h> bogusly including <sys/types.h>.

Gave rarpd back the ability to poke temporary entries into the arp
table; arptab.c is really a hacked up version of arp.c that only
supports adding temporary entries. (This stuff is nasty -- I wish I
knew what was so wrong with SIOCSARP/SIOCGARP/etc... that made the
BSD developers decide to take it out.) The idea here is that the
client issuing the rarp is expected to be in the middle of booting
and would therefore be unable to answer arp queries from other machines
on the wire. Having rarpd stuff a temporary entry for the booting
host into the local arp table helps keep arp requests from going unanswered.

Also added ether_print() and ether_ntoa() to the ether_addr.c module.
Eventually I'll get ether_aton() and ether_hostton() written and
then this file can be dropped straight into libc. (Assuming no one
objects, of course. :)
