This is a snapshot of my attempt to fit the FreeBSD networking code into
RTEMS. Things seem to be working!
Things that need to be done:
1) More documentation!
2) Figure out what's still not working :-)
3) Rationalize the include files. Right now I have a special
hack in the Makefile to ensure that I pick up the FreeBSD versions
of the include files that are duplicated between RTEMS
and FreeBSD.
The network device driver source should move to the BSP source tree.
4) Have a look at all the FIXME comments.
5) Go through and make sure that all the source files are
free of undesired copyright restrictions.
Initial Changes
===============
19-AUG-1998 snapshot
- Pulled BOOTP initialization out of rtems_glue. Applications which
don't used BOOTP are now about 5k smaller.
- Loopback interface is not installed by default, rather it is
attached like any other interface. Saves about 0.5 kbytes.
- Add rtems_bsdnet_show_if_stats();
- Moved test programs from below freebsd directory.
18-AUG-1998 snapshot
- Removed some include files that were already part of RTEMS.
- Cleaned up machine/types.h to prepare for inclusion in RTEMS source.
- Added syslog library routines -- much simpler than KA9Q version.
Sockets can be shared among tasks (as long as the send is
protected by a mutex) so there's no need for a Syslog Daemon.
16-AUG-1998 snapshot
- Table-driven configuration (networkconfig.h).
- Cleaned up rtems_bsdnet.h.
- BOOTP now retries properly -- Note to Joel:
The dichotomy between RTEMS and UNIX error codes is
a real pain!
14-AUG-1998 snapshot
- Added dummy getprotobyname() and getprotobynum() functions.
- Added socket ioctl.
- Added application-level entry to manipulate routing tables.
- Added non-BOOTP network initialization.
13-AUG-1998 snapshot
- Changed some BOOTP addresses from sockaddr_in to inaddr;
- Get DNS information from BOOTP reply.
- Got DNS lookups working.
Bloatware comes to RTEMS -- invoking gethostbyname() drags in
and extra 40 kbytes of code!
- Added hostname lookup program.
12-AUG-1998 snapshot
- Added startup delay to network initialization.
- More statistic-printing routines.
- Added TFTP driver and test program
- Modified TFTP test program to use networkconfig.h.
- Removed unused include files.
- Added from ftp://ftp.ca.FreeBSD.ORG/pub/FreeBSD/FreeBSD-current/src/lib/libc/net.
11-AUG-1998 snapshot.
- Added getpeername()
- Added M68k versions of IP checksum code
- Added TCP timing program to snapshot.
02-AUG-1998 snapshot.

/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
The following encoding technique is taken from RFC 1521 by Borenstein
and Freed. It is reproduced here in a slightly edited form for
convenience.
A 65-character subset of US-ASCII is used, enabling 6 bits to be
represented per printable character. (The extra 65th character, "=",
is used to signify a special processing function.)
The encoding process represents 24-bit groups of input bits as output
strings of 4 encoded characters. Proceeding from left to right, a
24-bit input group is formed by concatenating 3 8-bit input groups.
These 24 bits are then treated as 4 concatenated 6-bit groups, each
of which is translated into a single digit in the base64 alphabet.
Each 6-bit group is used as an index into an array of 64 printable
characters. The character referenced by the index is placed in the
output string.
Table 1: The Base64 Alphabet
Value Encoding Value Encoding Value Encoding Value Encoding
0 A 17 R 34 i 51 z
1 B 18 S 35 j 52 0
2 C 19 T 36 k 53 1
3 D 20 U 37 l 54 2
4 E 21 V 38 m 55 3
5 F 22 W 39 n 56 4
6 G 23 X 40 o 57 5
7 H 24 Y 41 p 58 6
8 I 25 Z 42 q 59 7
9 J 26 a 43 r 60 8
10 K 27 b 44 s 61 9
11 L 28 c 45 t 62 +
12 M 29 d 46 u 63 /
13 N 30 e 47 v
14 O 31 f 48 w (pad) =
15 P 32 g 49 x
16 Q 33 h 50 y
Special processing is performed if fewer than 24 bits are available
at the end of the data being encoded. A full encoding quantum is
always completed at the end of a quantity. When fewer than 24 input
bits are available in an input group, zero bits are added (on the
right) to form an integral number of 6-bit groups. Padding at the
end of the data is performed using the '=' character.
Since all base64 input is an integral number of octets, only the
-------------------------------------------------
following cases can arise:
(1) the final quantum of encoding input is an integral
multiple of 24 bits; here, the final unit of encoded
output will be an integral multiple of 4 characters
with no "=" padding,
(2) the final quantum of encoding input is exactly 8 bits;
here, the final unit of encoded output will be two
characters followed by two "=" padding characters, or
(3) the final quantum of encoding input is exactly 16 bits;
here, the final unit of encoded output will be three
characters followed by one "=" padding character.

.Sh DESCRIPTION
These routines convert 16 and 32 bit quantities between network
byte order and host byte order.
On machines which have a byte order which is the same as the network
order, routines are defined as null macros.
.Pp
These routines are most often used in conjunction with Internet
addresses and ports as returned by
.Xr gethostbyname 3
and
.Xr getservent 3 .
.Sh SEE ALSO

.Sh HISTORY
The
.Nm byteorder
functions appeared in
.Bx 4.2 .
.Sh BUGS
On the
.Tn VAX
bytes are handled backwards from most everyone else in
the world. This is not expected to be fixed in the near future.

.Nm ethers ,

.Nm ether_ntohost ,
.Nm ether_hostton
.Nd Ethernet address conversion and lookup routines
.Sh SYNOPSIS
.Fd #include <sys/types.h>
.Fd #include <sys/socket.h>
.Fd #include <net/ethernet.h>
.Ft int
.Fn ether_line "char *l" "struct ether_addr *e" "char *hostname"
.Ft struct ether_addr *
.Fn ether_aton "char *a"
.Ft char *
.Fn ether_ntoa "struct ether_addr *n"
.Ft int
.Fn ether_ntohost "char *hostname" "struct ether_addr *e"
.Ft int
.Fn ether_hostton "char *hostname" "struct ether_addr *e"
.Sh DESCRIPTION
These functions operate on ethernet addresses using an
.Ar ether_addr
structure, which is defined in the header file
.Aq Pa netinet/if_ether.h :
.Bd -literal -offset indent
/*
* The number of bytes in an ethernet (MAC) address.
*/
#define ETHER_ADDR_LEN 6
/*
* Structure of a 48-bit Ethernet address.
*/
struct ether_addr {
u_char octet[ETHER_ADDR_LEN];
};
.Ed
.Pp
The function
.Fn ether_line
scans
.Ar l ,
an
.Tn ASCII
string in
.Xr ethers 5
format and sets
.Ar e
to the ethernet address specified in the string and
.Ar h
to the hostname. This function is used to parse lines from
.Pa /etc/ethers
into their component parts.
.Pp
The
.Fn ether_aton
function converts an
.Tn ASCII
representation of an ethernet address into an
.Ar ether_addr
structure. Likewise,
.Fn ether_ntoa
converts an ethernet address specified as an
.Ar ether_addr
structure into an
.Tn ASCII
string.
.Pp
The
.Fn ether_ntohost
and
.Fn ether_hostton
functions map ethernet addresses to their corresponding hostnames
as specified in the
.Pa /etc/ethers
database.
.Fn ether_ntohost
converts from ethernet address to hostname, and
.Fn ether_hostton
converts from hostname to ethernet address.
.Sh RETURN VALUES
.Fn ether_line
returns zero on success and non-zero if it was unable to parse
any part of the supplied line
.Ar l .
It returns the extracted ethernet address in the supplied
.Ar ether_addr
structure
.Ar e
and the hostname in the supplied string
.Ar h .
.Pp
On success,
.Fn ether_ntoa
returns a pointer to a string containing an
.Tn ASCII
representation of an ethernet address. If it is unable to convert
the supplied
.Ar ether_addr
structure, it returns a
.Dv NULL
pointer. Likewise,
.Fn ether_aton
returns a pointer to an
.Ar ether_addr
structure on success and a
.Dv NULL
pointer on failure.
.Pp
The
.Fn ether_ntohost
and
.Fn ether_hostton
functions both return zero on success or non-zero if they were
unable to find a match in the
.Pa /etc/ethers
database.
.Sh NOTES
The user must insure that the hostname strings passed to the
the
.Fn ether_line ,
.Fn ether_ntohost
and
.Fn ether_hostton
functions are large enough to contain the returned hostnames.
.Sh NIS INTERACTION
If the
.Pa /etc/ethers
contains a line with a single + in it, the
.Fn ether_ntohost
and
.Fn ether_hostton
functions will attempt to consult the NIS
.Pa ethers.byname
and
.Pa ethers.byaddr
maps in addition to the data in the
.Pa /etc/ethers
file.
.Sh SEE ALSO
.Xr yp 4 ,
.Xr ethers 5
.Sh BUGS
.Pp
The
.Fn ether_aton
and
.Fn ether_ntoa
functions returns values that are stored in static memory areas
which may be overwritten the next time they are called.
.Sh HISTORY
This particular implementation of the
.Nm ethers
library functions were written for and first appeared in
.Fx 2.1 .

.Fn hstrerror "int err"
.Sh DESCRIPTION
The
.Fn gethostbyname ,
.Fn gethostbyname2
and
.Fn gethostbyaddr
functions
each return a pointer to an object with the
following structure describing an internet host
referenced by name or by address, respectively.
This structure contains either the information obtained from the name server,
.Xr named 8 ,
or broken-out fields from a line in
.Pa /etc/hosts .
If the local name server is not running these routines do a lookup in
.Pa /etc/hosts .
.Bd -literal
struct hostent {
char *h_name; /* official name of host */
char **h_aliases; /* alias list */
int h_addrtype; /* host address type */
int h_length; /* length of address */
char **h_addr_list; /* list of addresses from name server */
};
#define h_addr h_addr_list[0] /* address, for backward compatibility */
.Ed
.Pp
The members of this structure are:
.Bl -tag -width h_addr_list
.It Fa h_name
Official name of the host.
.It Fa h_aliases
A NULL-terminated array of alternate names for the host.
.It Fa h_addrtype
The type of address being returned; usually
.Dv AF_INET .
.It Fa h_length
The length, in bytes, of the address.
.It Fa h_addr_list
A NULL-terminated array of network addresses for the host.
Host addresses are returned in network byte order.
.It Fa h_addr
The first address in
.Fa h_addr_list ;
this is for backward compatibility.
.El
.Pp
When using the nameserver,
.Fn gethostbyname
and
.Fn gethostbyname
will search for the named host in the current domain and its parents
unless the name ends in a dot.
If the name contains no dot, and if the environment variable
.Dq Ev HOSTALIASES
contains the name of an alias file, the alias file will first be searched
for an alias matching the input name.
See
.Xr hostname 7
for the domain search procedure and the alias file format.
.Pp
The
.Fn gethostbyname2
function is an evolution of
.Fn gethostbyname
which is intended to allow lookups in address families other than
.Dv AF_INET ,
for example
.Dv AF_INET6 .
Currently the
.Fa af
argument must be specified as
.Dv AF_INET
else the function will return
.Dv NULL
after having set
.Va h_errno
to
.Dv NETDB_INTERNAL
.Pp
The
.Fn sethostent
function
may be used to request the use of a connected
.Tn TCP
socket for queries.
If the
.Fa stayopen
flag is non-zero,
this sets the option to send all queries to the name server using
.Tn TCP
and to retain the connection after each call to
.Fn gethostbyname ,
.Fn gethostbyname2
or
.Fn gethostbyaddr .
Otherwise, queries are performed using
.Tn UDP
datagrams.
.Pp
The
.Fn endhostent
function
closes the
.Tn TCP
connection.
.Pp
The
.Fn herror
function writes a message to the diagnostic output consisting of the
string parameter
.Fa s ,
the constant string ": ", and a message corresponding to the value of
.Va h_errno .
.Pp
The
.Fn hstrerror
function returns a string which is the message text corresponding to the
value of the
.Fa err
parameter.
.Sh FILES
.Bl -tag -width /etc/resolv.conf -compact
.It Pa /etc/hosts
.It Pa /etc/host.conf
.It Pa /etc/resolv.conf
.El
.Sh DIAGNOSTICS
Error return status from
.Fn gethostbyname ,
.Fn gethostbyname2
and
.Fn gethostbyaddr
is indicated by return of a null pointer.
The external integer
.Va h_errno
may then be checked to see whether this is a temporary failure
or an invalid or unknown host.
The routine
.Fn herror
can be used to print an error message describing the failure.
If its argument
.Fa string
is
.Pf non Dv -NULL ,
it is printed, followed by a colon and a space.
The error message is printed with a trailing newline.
.Pp
The variable
.Va h_errno
can have the following values:
.Bl -tag -width HOST_NOT_FOUND
.It Dv HOST_NOT_FOUND
No such host is known.
.It Dv TRY_AGAIN
This is usually a temporary error
and means that the local server did not receive
a response from an authoritative server.
A retry at some later time may succeed.
.It Dv NO_RECOVERY
Some unexpected server failure was encountered.
This is a non-recoverable error.
.It Dv NO_DATA
The requested name is valid but does not have an IP address;
this is not a temporary error.
This means that the name is known to the name server but there is no address
associated with this name.
Another type of request to the name server using this domain name
will result in an answer;
for example, a mail-forwarder may be registered for this domain.
.El
.Sh SEE ALSO
.Xr resolver 3 ,
.Xr hosts 5 ,
.Xr hostname 7 ,
.Xr named 8
.Sh CAVEAT
The
.Fn gethostent
function
is defined, and
.Fn sethostent
and
.Fn endhostent
are redefined,
when
.Xr libc 3
is built to use only the routines to lookup in
.Pa /etc/hosts
and not the name server.
.Pp
The
.Fn gethostent
function
reads the next line of
.Pa /etc/hosts ,
opening the file if necessary.
.Pp
The
.Fn sethostent
function
opens and/or rewinds the file
.Pa /etc/hosts .
If the
.Fa stayopen
argument is non-zero,
the file will not be closed after each call to
.Fn gethostbyname ,
.Fn gethostbyname2
or
.Fn gethostbyaddr .
.Pp
The
.Fn endhostent
function
closes the file.
.Sh HISTORY
The
.Fn herror
function appeared in
.Bx 4.3 .
The
.Fn endhostent ,
.Fn gethostbyaddr ,
.Fn gethostbyname ,
.Fn gethostent ,
and
.Fn sethostent
functions appeared in
.Bx 4.2 .
The
.Fn gethostbyname2
function first appeared in bind-4.9.4.
.Sh BUGS
These functions use static data storage;
if the data is needed for future use, it should be
copied before any subsequent calls overwrite it.
Only the Internet
address format is currently understood.

.Sh NAME
.Nm getnetent ,
.Nm getnetbyaddr ,
.Nm getnetbyname ,
.Nm setnetent ,
.Nm endnetent
.Nd get network entry
.Sh SYNOPSIS
.Fd #include <netdb.h>
.Ft struct netent *
.Fn getnetent void
.Ft struct netent *
.Fn getnetbyname "const char *name"
.Ft struct netent *
.Fn getnetbyaddr "unsigned long net" "int type"
.Ft void
.Fn setnetent "int stayopen"
.Ft void
.Fn endnetent void
.Sh DESCRIPTION
The
.Fn getnetent ,
.Fn getnetbyname ,
and
.Fn getnetbyaddr
functions
each return a pointer to an object with the
following structure
containing the broken-out
fields of a line in the network data base,
.Pa /etc/networks .
.Bd -literal -offset indent
struct netent {
char *n_name; /* official name of net */
char **n_aliases; /* alias list */
int n_addrtype; /* net number type */
unsigned long n_net; /* net number */
};
.Ed
.Pp
The members of this structure are:
.Bl -tag -width n_addrtype
.It Fa n_name
The official name of the network.
.It Fa n_aliases
A zero terminated list of alternate names for the network.
.It Fa n_addrtype
The type of the network number returned; currently only AF_INET.
.It Fa n_net
The network number. Network numbers are returned in machine byte
order.
.El
.Pp
The
.Fn getnetent
function
reads the next line of the file, opening the file if necessary.
.Pp
The
.Fn setnetent
function
opens and rewinds the file. If the
.Fa stayopen
flag is non-zero,
the net data base will not be closed after each call to
.Fn getnetbyname
or
.Fn getnetbyaddr .
.Pp
The
.Fn endnetent
function
closes the file.
.Pp
The
.Fn getnetbyname
function
and
.Fn getnetbyaddr
sequentially search from the beginning
of the file until a matching
net name or
net address and type is found,
or until
.Dv EOF
is encountered. The
.Fa type
must be
.Dv AF_INET .
Network numbers are supplied in host order.
.Sh FILES
.Bl -tag -width /etc/networks -compact
.It Pa /etc/networks
.El
.Sh DIAGNOSTICS
Null pointer
(0) returned on
.Dv EOF
or error.
.Sh SEE ALSO
.Xr networks 5
.Pp
.%T RFC 1101
.Sh HISTORY
The
.Fn getnetent ,
.Fn getnetbyaddr ,
.Fn getnetbyname ,
.Fn setnetent ,
and
.Fn endnetent
functions appeared in
.Bx 4.2 .
.Sh BUGS
The data space used by
these functions is static; if future use requires the data, it should be
copied before any subsequent calls to these functions overwrite it.
Only Internet network
numbers are currently understood.
Expecting network numbers to fit
in no more than 32 bits is probably
naive.

.Sh NAME
.Nm getservent ,
.Nm getservbyport ,
.Nm getservbyname ,
.Nm setservent ,
.Nm endservent
.Nd get service entry
.Sh SYNOPSIS
.Fd #include <netdb.h>
.Ft struct servent *
.Fn getservent
.Ft struct servent *
.Fn getservbyname "const char *name" "const char *proto"
.Ft struct servent *
.Fn getservbyport "int port" "const char *proto"
.Ft void
.Fn setservent "int stayopen"
.Ft void
.Fn endservent void
.Sh DESCRIPTION
The
.Fn getservent ,
.Fn getservbyname ,
and
.Fn getservbyport
functions
each return a pointer to an object with the
following structure
containing the broken-out
fields of a line in the network services data base,
.Pa /etc/services .
.Bd -literal -offset indent
struct servent {
char *s_name; /* official name of service */
char **s_aliases; /* alias list */
int s_port; /* port service resides at */
char *s_proto; /* protocol to use */
};
.Ed
.Pp
The members of this structure are:
.Bl -tag -width s_aliases
.It Fa s_name
The official name of the service.
.It Fa s_aliases
A zero terminated list of alternate names for the service.
.It Fa s_port
The port number at which the service resides.
Port numbers are returned in network byte order.
.It Fa s_proto
The name of the protocol to use when contacting the
service.
.El
.Pp
The
.Fn getservent
function
reads the next line of the file, opening the file if necessary.
.Pp
The
.Fn setservent
function
opens and rewinds the file. If the
.Fa stayopen
flag is non-zero,
the net data base will not be closed after each call to
.Fn getservbyname
or
.Fn getservbyport .
.Pp
The
.Fn endservent
function
closes the file.
.Pp
The
.Fn getservbyname
and
.Fn getservbyport
functions
sequentially search from the beginning
of the file until a matching
protocol name or
port number is found,
or until
.Dv EOF
is encountered.
If a protocol name is also supplied (non-
.Dv NULL ) ,
searches must also match the protocol.
.ne 1i
.Sh FILES
.Bl -tag -width /etc/services -compact
.It Pa /etc/services
.El
.Sh DIAGNOSTICS
Null pointer
(0) returned on
.Dv EOF
or error.
.Sh SEE ALSO
.Xr getprotoent 3 ,
.Xr services 5
.Sh HISTORY
The
.Fn getservent ,
.Fn getservbyport ,
.Fn getservbyname ,
.Fn setservent ,
and
.Fn endservent
functions appeared in
.Bx 4.2 .
.Sh BUGS
These functions use static data storage;
if the data is needed for future use, it should be
copied before any subsequent calls overwrite it.
Expecting port numbers to fit in a 32 bit
quantity is probably naive.
