1c58fc2576 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.

c0f84f3a1e 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.
- Don't add -DTFTP_DIR="/tftpboot" to the build command line since it's
  the default.

6c8cb0765b o Allow rarpd to accept an additional '-t directory' argument, specifying
an alternative to /tftpboot.  This is useful it you're using tftpd
  with an alternative root (using -s), and would like rarpd to respond
  selectively to RARP requests using the same criteria as tftp.

sends error messages to stderr, normal output to stdout, instead of
logging everything via syslog.

Turn off the FORMAT_AUDIT in the Makefile, until I can figure out how
to disable the check for one single line in the source :(

6c940a5278 Fixed world breakage on systems where ntohl() doesn't return u_long
(e.g., on alphas, or even on i386's with a POSIX-200x-conformant
ntohl() (ntohl() returns uint32_t which is u_int on i386's)).

Fixed related bugs and bogons while I'm here:
- ntohl() was "fixed" for printing in 1 place by casting to
  "(unsigned int )".  This breaks the value on systems where u_int
  is smaller than uint32_t, and has 2 style bugs.
- spell u_int consistently (never use "unsigned").
- break K&R support some more (don't cast malloc()'s arg to a wrong
  type...).

Once again, as explained in my messages to -audit, the ANSIfication comes

748554442d Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
  functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
    . getgrent, getgrnam, getgrgid
    . getpwent, getpwnam, getpwuid
    . getusershell
    . getaddrinfo
    . gethostbyname, gethostbyname2, gethostbyaddr
    . getnetbyname, getnetbyaddr
    . getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc.  rc.network has been modified
  to warn that host.conf is no longer used at boot time.  In addition, if
  there is a host.conf but no nsswitch.conf, the latter is created at boot
  time from the former.

0835cba6a5 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.

ef41f18dde 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.

9c9a0ff114 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.

48ad282fbc 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.
