feat: switch iperf3 to JNI with 3.19 source

Browse Source 
- Switch from bundled iperf3 binary (Process.start) to JNI compilation
- iperf3 3.21 source API was incompatible (start_time, iperf_strerror, etc.)
- iperf3 3.19 source is proven to work (used by CellularLab)
- CMakeLists.txt updated: config.h generated into cpp/iperf/ for correct include paths
- iperf_jni.c fixed for 3.19 API (no start_time on iperf_test)
- getTestProgress() returns g_test->duration as fallback (no real-time elapsed tracking yet)
- NDK CMake pinned to 3.22.1
- UI layer updated: removed Iperf3BinaryPathProvider references
- Tests updated: TestRunViewModelTest matches new service interface
- pubspec.yaml: removed iperf3 assets bundle, added http dependency
- AndroidManifest: INTERNET permission (needed for hostname resolution)

.TH IPERF3 1 "May 2025" ESnet "User Manuals"
.SH NAME
iperf3 \- perform network throughput tests
.SH SYNOPSIS
.B iperf3 -s [
.I options
.B ]
.br
.B iperf3 -c
.I server
.B [
.I options
.B ]
.SH DESCRIPTION
iperf3 is a tool for performing network throughput measurements.
It can test TCP, UDP, or SCTP throughput.
To perform an iperf3 test the user must establish both a server and a
client.
.PP
The iperf3 executable contains both client and server functionality.
An iperf3 server can be started using either of the -s or
--server command-line parameters, for example:
.IP
\fCiperf3 -s\fR
.IP
\fCiperf3 --server \fR
.PP
Note that many iperf3 parameters have both short (-s) and long
(--server) forms.
In this section we will generally use the short form of command-line
flags, unless only the long form of a flag is available.
.PP
By default, the iperf3 server listens on TCP port 5201 for connections
from an iperf3 client.
A custom port can be specified by using the -p flag, for
example:
.IP
\fCiperf3 -s -p 5002\fR
.PP
After the server is started, it will listen for connections from
iperf3 clients (in other words, the iperf3 program run in client
mode).
The client mode can be started using the -c command-line option,
which also requires a host to which iperf3 should connect.
The host can by specified by hostname, IPv4 literal, or IPv6 literal:
.IP

If the iperf3 server is running on a non-default TCP port, that port
number needs to be specified on the client as well:
.IP
\fCiperf3 -c iperf3.example.com -p 5002\fR
.PP
The initial TCP connection is used to exchange test parameters,
control the start and end of the test, and to exchange test results.
This is sometimes referred to as the "control connection".
The actual test data is sent over a separate TCP connection, as a
separate flow of UDP packets, or as an independent SCTP connection,
depending on what protocol was specified by the client.
.PP
Normally, the test data is sent from the client to the server, and
measures the upload speed of the client.
Measuring the download speed from the server can be done by specifying
the -R flag on the client.
This causes data to be sent from the server to the client.
.IP
\fCiperf3 -c iperf3.example.com -p 5202 -R
.PP
Results are displayed on both the client and server.
There will be at least one line of output per measurement interval (by
default a measurement interval lasts for one second, but this can be
changed by the -i option).
Each line of output includes (at least) the time since the start of
the test, amount of data transferred during the interval, and the
average bitrate over that interval.
Note that the values for each measurement interval are taken from the
point of view of the endpoint process emitting that output (in other
words, the output on the client shows the measurement interval data for
the client.
.PP
At the end of the test is a set of statistics that shows (at
least as much as possible) a summary of the test as seen by both the
sender and the receiver, with lines tagged accordingly.
Recall that by default the client is the sender and the server is the
receiver, although as indicated above, use of the \fC-R\fR flag will
reverse these roles.
.PP
The client can be made to retrieve the server-side output for a given
test by specifying the --get-server-output flag.
.PP
Either the client or the server can produce its output in a JSON
structure, useful for integration with other programs, by passing it
the -J flag.
Normally the contents of the JSON structure are only completely known
after the test has finished, no JSON output will be emitted until the
end of the test.
By enabling line-delimited JSON multiple objects will be emitted to
provide a real-time parsable JSON output.
.PP
iperf3 has a (overly) large set of command-line options that can be
used to set the parameters of a test.
They are given in the "GENERAL OPTIONS" section of the manual page
below, as well as summarized in iperf3's help output, which can be
viewed by running iperf3 with the -h flag.
.SH "GENERAL OPTIONS"
.TP
.BR -p ", " --port " \fIn\fR"
set server port to listen on/connect to to \fIn\fR (default 5201)
.TP
.BR -f ", " --format " "
[kmgtKMGT] format to report: Kbits/Mbits/Gbits/Tbits
.TP
.BR -i ", " --interval " \fIn\fR"
pause \fIn\fR seconds between periodic throughput reports;
default is 1, use 0 to disable
.TP
.BR -I ", " --pidfile " \fIfile\fR"
write a file with the process ID, most useful when running as a daemon.
.TP
.BR -F ", " --file " \fIname\fR"
Use a file as the source (on the sender) or sink (on the receiver) of
data, rather than just generating random data or throwing it away.
This feature is used for finding whether or not the storage subsystem
is the bottleneck for file transfers.
It does not turn iperf3 into a file transfer tool.
The length, attributes, and in some cases contents of the received
file may not match those of the original file.
.TP
.BR -A ", " --affinity " \fIn/n,m\fR"
Set the CPU affinity, if possible (Linux, FreeBSD, and Windows only).
On both the client and server you can set the local affinity by using
the \fIn\fR form of this argument (where \fIn\fR is a CPU number).
In addition, on the client side you can override the server's
affinity for just that one test, using the \fIn,m\fR form of
argument.
Note that when using this feature, a process will only be bound
to a single CPU (as opposed to a set containing potentially multiple
CPUs).
.TP
.BR -B ", " --bind " \fIhost\fR[\fB%\fIdev\fR]"
bind to the specific interface associated with address \fIhost\fR.
If an optional interface is specified, it is treated as a shortcut
for \fB--bind-dev \fIdev\fR.
Note that a percent sign and interface device name are required for IPv6 link-local address literals.
.TP
.BR --bind-dev " \fIdev\fR"
bind to the specified network interface.
This option uses SO_BINDTODEVICE, and may require root permissions.
(Available on Linux and possibly other systems.)
.TP
.BR -V ", " --verbose " "
give more detailed output
.TP
.BR -J ", " --json " "
output in JSON format
.TP
.BR --json-stream " "
output in line-delimited JSON format
.TP
.BR --logfile " \fIfile\fR"
send output to a log file.
.TP
.BR --forceflush " "
force flushing output at every interval.
Used to avoid buffering when sending output to pipe.
.TP
.BR --timestamps "[\fB=\fIformat\fR]"
prepend a timestamp at the start of each output line.
By default, timestamps have the format emitted by
.BR ctime ( 1 ).
Optionally, \fC=\fR followed by
a format specification can be passed to customize the
timestamps, see
.BR strftime ( 3 ).
If this optional format is given, the \fC=\fR must immediately
follow the \fB--timestamps\fR option with no whitespace intervening.
.TP
.BR --rcv-timeout " \fI#\fR"
set idle timeout for receiving data during active tests. The receiver
will halt a test if no data is received from the sender for this
number of ms (default to 120000 ms, or 2 minutes).
.TP
.BR --snd-timeout " \fI#\fR"
set timeout for unacknowledged TCP data (on both test and control
connections) This option can be used to force a faster test timeout
in case of a network partition during a test. The required
parameter is specified in ms, and defaults to the system settings.
This functionality depends on the TCP_USER_TIMEOUT socket option, and
will not work on systems that do not support it.
.TP
.BR --use-pkcs1-padding
This option is only meaningful when using iperf3's authentication
features. Versions of iperf3 prior to 3.17 used PCKS1 padding in the
RSA-encrypted credentials, which was vulnerable to a side-channel
attack that could reveal a server's private key. Beginning with
iperf-3.17, OAEP padding is used, however this is a breaking change
that is not compatible with older iperf3 versions. Use this option to
preserve the less secure, but more compatible, behavior.
.TP
.BR -m ", " --mptcp " "
use mptcp variant for the current protocol. This only applies to
TCP and enables MPTCP usage.
.TP
.BR -d ", " --debug " "
emit debugging output.
Primarily (perhaps exclusively) of use to developers.
.TP
.BR -v ", " --version " "
show version information and quit
.TP
.BR -h ", " --help " "
show a help synopsis
.SH "SERVER SPECIFIC OPTIONS"
.TP
.BR -s ", " --server " "
run in server mode
.TP
.BR -D ", " --daemon " "
run the server in background as a daemon
.TP
.BR -1 ", " --one-off
handle one client connection, then exit. If an idle time is set, the
server will exit after that amount of time with no connection.
.TP
.BR --idle-timeout " \fIn\fR"
restart the server after \fIn\fR seconds in case it gets stuck. In
one-off mode, this is the number of seconds the server will wait
before exiting.
.TP
.BR --server-bitrate-limit " \fIn\fR[KMGT]"
set a limit on the server side, which will cause a test to abort if
the client specifies a test of more than \fIn\fR bits per second, or
if the average data sent or received by the client (including all data
streams) is greater than \fIn\fR bits per second. The default limit
is zero, which implies no limit. The interval over which to average
the data rate is 5 seconds by default, but can be specified by adding
a '/' and a number to the bitrate specifier.
.TP
.BR --rsa-private-key-path " \fIfile\fR"
path to the RSA private key (not password-protected) used to decrypt
authentication credentials from the client (if built with OpenSSL
support).
.TP
.BR --authorized-users-path " \fIfile\fR"
path to the configuration file containing authorized users credentials to run
iperf tests (if built with OpenSSL support).
The file is a comma separated list of usernames and password hashes;
more information on the structure of the file can be found in the
EXAMPLES section.
.TP
.BR --time-skew-threshold second " \fIseconds\fR"
time skew threshold (in seconds) between the server and client
during the authentication process.
.SH "CLIENT SPECIFIC OPTIONS"
.TP
.BR -c ", " --client " \fIhost\fR[\fB%\fIdev\fR]"
run in client mode, connecting to the specified server.
By default, a test consists of sending data from the client to the
server, unless the \-R flag is specified.
If an optional interface is specified, it is treated as a shortcut
for \fB--bind-dev \fIdev\fR.
Note that a percent sign and interface device name are required for IPv6 link-local address literals.
.TP
.BR --sctp
use SCTP rather than TCP (FreeBSD and Linux)
.TP
.BR -u ", " --udp
use UDP rather than TCP
.TP
.BR --connect-timeout " \fIn\fR"
set timeout for establishing the initial control connection to the
server, in milliseconds.
The default behavior is the operating system's timeout for TCP
connection establishment.
Providing a shorter value may speed up detection of a down iperf3
server.
.TP
.BR -b ", " --bitrate " \fIn\fR[KMGT]"
set target bitrate to \fIn\fR bits/sec (default 1 Mbit/sec for UDP,
unlimited for TCP/SCTP).
If there are multiple streams (\-P flag), the throughput limit is applied
separately to each stream.
You can also add a '/' and a number to the bitrate specifier.
This is called "burst mode".
It will send the given number of packets without pausing, even if that
temporarily exceeds the specified throughput limit.
Setting the target bitrate to 0 will disable bitrate limits
(particularly useful for UDP tests).
This throughput limit is implemented internally inside iperf3, and is
available on all platforms.
Compare with the \--fq-rate flag.
This option replaces the \--bandwidth flag, which is now deprecated
but (at least for now) still accepted.
.TP
.BR --pacing-timer " \fIn\fR[KMGT]"
set pacing timer interval in microseconds (default 1000 microseconds,
or 1 ms).
This controls iperf3's internal pacing timer for the \-b/\--bitrate
option.
The timer fires at the interval set by this parameter.
Smaller values of the pacing timer parameter smooth out the traffic
emitted by iperf3, but potentially at the cost of performance due to
more frequent timer processing.
.TP
.BR --fq-rate " \fIn\fR[KMGT]"
Set a rate to be used with fair-queueing based socket-level pacing,
in bits per second.
This pacing (if specified) will be in addition to any pacing due to
iperf3's internal throughput pacing (\-b/\--bitrate flag), and both can be
specified for the same test.
Only available on platforms supporting the
\fCSO_MAX_PACING_RATE\fR socket option (currently only Linux).
The default is no fair-queueing based pacing.
.TP
.BR --no-fq-socket-pacing
This option is deprecated and will be removed.
It is equivalent to specifying --fq-rate=0.
.TP
.BR -t ", " --time " \fIn\fR"
time in seconds to transmit for (default 10 secs)
.TP
.BR -n ", " --bytes " \fIn\fR[KMGT]"
number of bytes to transmit (instead of \-t)
.TP
.BR -k ", " --blockcount " \fIn\fR[KMGT]"
number of blocks (packets) to transmit (instead of \-t or \-n)
.TP
.BR -l ", " --length " \fIn\fR[KMGT]"
length of buffer to read or write. For TCP tests, the default value
is 128KB.
In the case of UDP, iperf3 tries to dynamically determine a reasonable
sending size based on the path MTU; if that cannot be determined it
uses 1460 bytes as a sending size.
For SCTP tests, the default size is 64KB.
.TP
.BR --cport " \fIport\fR"
bind data streams to a specific client port (for TCP and UDP only,
default is to use an ephemeral port)
.TP
.BR -P ", " --parallel " \fIn\fR"
number of parallel client streams to run. iperf3 will spawn off a
separate thread for each test stream. Using multiple streams may
result in higher throughput than a single stream.
.TP
.BR -R ", " --reverse
reverse the direction of a test, so that the server sends data to the
client
.TP
.BR --bidir
test in both directions (normal and reverse), with both the client and
server sending and receiving data simultaneously
.TP
.BR -w ", " --window " \fIn\fR[KMGT]"
set socket buffer size / window size.
This value gets sent to the server and used on that side too; on both
sides this option sets both the sending and receiving socket buffer sizes.
This option can be used to set (indirectly) the maximum TCP window size.
Note that on Linux systems, the effective maximum window size is approximately
double what is specified by this option (this behavior is not a bug in iperf3
but a "feature" of the Linux kernel, as documented by tcp(7) and socket(7)).
.TP
.BR -M ", " --set-mss " \fIn\fR"
set TCP/SCTP maximum segment size (MTU - 40 bytes)
.TP
.BR -N ", " --no-delay " "
set TCP/SCTP no delay, disabling Nagle's Algorithm
.TP
.BR -4 ", " --version4 " "
only use IPv4
.TP
.BR -6 ", " --version6 " "
only use IPv6
.TP
.BR -S ", " --tos " \fIn\fR"
set the IP type of service. The usual prefixes for octal and hex can be used,
i.e. 52, 064 and 0x34 all specify the same value.
.TP
.BR "--dscp " \fIdscp\fR
set the IP DSCP bits. Both numeric and symbolic values are accepted. Numeric
values can be specified in decimal, octal and hex (see --tos above).
.TP
.BR -L ", " --flowlabel " \fIn\fR"
set the IPv6 flow label (currently only supported on Linux)
.TP
.BR -X ", " --xbind " \fIname\fR"
Bind SCTP associations to a specific subset of links using sctp_bindx(3).
The \fB--B\fR flag will be ignored if this flag is specified.
Normally SCTP will include the protocol addresses of all active links
on the local host when setting up an association. Specifying at least
one \fB--X\fR name will disable this behaviour.
This flag must be specified for each link to be included in the
association, and is supported for both iperf servers and clients
(the latter are supported by passing the first \fB--X\fR argument to bind(2)).
Hostnames are accepted as arguments and are resolved using
getaddrinfo(3).
If the \fB--4\fR or \fB--6\fR flags are specified, names
which do not resolve to addresses within the
specified protocol family will be ignored.
.TP
.BR --nstreams " \fIn\fR"
Set number of SCTP streams.
.TP
.BR -Z ", " --zerocopy " "
Use a "zero copy" method of sending data, such as sendfile(2),
instead of the usual write(2).
.TP
.BR --skip-rx-copy
Ignored received packet data, using the MSG_TRUNC flag to the
recv(2) system call.
.TP
.BR -O ", " --omit " \fIn\fR"
Perform pre-test for N seconds and omit the pre-test statistics, to skip past the TCP slow-start
period.
.TP
.BR -T ", " --title " \fIstr\fR"
Prefix every output line with this string.
.TP
.BR --extra-data " \fIstr\fR"
Specify an extra data string field to be included in JSON output.
.TP
.BR -C ", " --congestion " \fIalgo\fR"
Set the congestion control algorithm (Linux and FreeBSD only). An
older
.B --linux-congestion
synonym for this flag is accepted but is deprecated.
.TP
.BR "--get-server-output"
Get the output from the server.
The output format is determined by the server (in particular, if the
server was invoked with the \fB--json\fR flag, the output will be in
JSON format, otherwise it will be in human-readable format).
If the client is run with \fB--json\fR, the server output is included
in a JSON object; otherwise it is appended at the bottom of the
human-readable output.
.TP
.BR --udp-counters-64bit
Use 64-bit counters in UDP test packets.
The use of this option can help prevent counter overflows during long
or high-bitrate UDP tests. Both client and server need to be running
at least version 3.1 for this option to work. It may become the
default behavior at some point in the future.
.TP
.BR --repeating-payload
Use repeating pattern in payload, instead of random bytes.
The same payload is used in iperf2 (ASCII '0..9' repeating).
It might help to test and reveal problems in networking gear with hardware
compression (including some WiFi access points), where iperf2 and iperf3
perform differently, just based on payload entropy.
.TP
.BR --dont-fragment
Set the IPv4 Don't Fragment (DF) bit on outgoing packets.
Only applicable to tests doing UDP over IPv4.
.TP
.BR --username " \fIusername\fR"
username to use for authentication to the iperf server (if built with
OpenSSL support).
The password will be prompted for interactively when the test is run. Note,
the password to use can also be specified via the IPERF3_PASSWORD environment
variable. If this variable is present, the password prompt will be skipped.
.TP
.BR --rsa-public-key-path " \fIfile\fR"
path to the RSA public key used to encrypt authentication credentials
(if built with OpenSSL support)
.SH EXAMPLES
.SS "Authentication - RSA Keypair"
The authentication feature of iperf3 requires an RSA public keypair.
The public key is used to encrypt the authentication token containing the
user credentials, while the private key is used to decrypt the authentication token.
The private key must be in PEM format and additionally must not have a
password set.
The public key must be in PEM format and use SubjectPrefixKeyInfo encoding.
An example of a set of UNIX/Linux commands using OpenSSL
to generate a correctly-formed keypair follows:
.sp 1
.in +.5i
> openssl genrsa -des3 -out private.pem 2048
.sp 0
> openssl rsa -in private.pem -outform PEM -pubout -out public.pem
.sp 0
> openssl rsa -in private.pem -out private_not_protected.pem -outform PEM
.in -.5i
.sp 1
After these commands, the public key will be contained in the file
public.pem and the private key will be contained in the file
private_not_protected.pem.
.SS "Authentication - Authorized users configuration file"
A simple plaintext file must be provided to the iperf3 server in order to specify
the authorized user credentials.
The file is a simple list of comma-separated pairs of a username and a
corresponding password hash.
The password hash is a SHA256 hash of the string "{$user}$password".
The file can also contain commented lines (starting with the \fC#\fR
character).
An example of commands to generate the password hash on a UNIX/Linux system
is given below:
.sp 1
.in +.5i
> S_USER=mario S_PASSWD=rossi
.sp 0
> echo -n "{$S_USER}$S_PASSWD" | sha256sum | awk '{ print $1 }'
.in -.5i
.sp 1
An example of a password file (with an entry corresponding to the
above username and password) is given below:
.sp 0
.in +.5i
> cat credentials.csv
.sp 0
# file format: username,sha256
.sp 0

.TH LIBIPERF 3 "January 2022" ESnet "User Manuals"
.SH NAME
libiperf \- API for iperf3 network throughput tester
.SH SYNOPSIS
#include <iperf_api.h>
.br
\-liperf
.SH DESCRIPTION
.PP
Libiperf gives you access to all the functionality of the iperf3
network testing tool.
You can build it directly into your own program, instead of having
to run it as a shell command.
.SH CALLS
Initialization / termination:
.nf
struct iperf_test *iperf_new_test();
int iperf_defaults(struct iperf_test *t);
void iperf_free_test(struct iperf_test *t);
.fi
Setting test parameters:
.nf
void iperf_set_test_role( struct iperf_test *pt, char role );
void iperf_set_test_bind_address( struct iperf_test *t, char *bind_address );
void iperf_set_test_bind_dev( struct iperf_test *t, char *bind_dev );
void iperf_set_test_server_hostname( struct iperf_test *t, char *server_host );
void iperf_set_test_server_port( struct iperf_test *t, int server_port );
void iperf_set_test_duration( struct iperf_test *t, int duration );
void iperf_set_test_blksize( struct iperf_test *t, int blksize );
void iperf_set_test_num_streams( struct iperf_test *t, int num_streams );
void iperf_set_test_json_output( struct iperf_test *t, int json_output );
void iperf_set_test_json_stream( struct iperf_test *t, int json_stream );
int iperf_has_zerocopy( void );
void iperf_set_test_zerocopy( struct iperf_test* t, int zerocopy );
void iperf_set_test_tos( struct iperf_test* t, int tos );
.fi
Authentication functions:
.nf
void iperf_set_test_client_username(struct iperf_test *ipt, char *client_username)
void iperf_set_test_client_password(struct iperf_test *ipt, char *client_password)
void iperf_set_test_client_rsa_pubkey(struct iperf_test *ipt, char *client_rsa_pubkey_base64)
.fi
Running a test:
.nf
int iperf_run_client(struct iperf_test *);
int iperf_run_server(struct iperf_test *);
void iperf_reset_test(struct iperf_test *);
.fi
Output:
.nf
FILE *iperf_get_test_outfile(struct iperf_test *);
char* iperf_get_test_json_output_string(struct iperf_test *);
.fi
Error reporting:
.nf
void iperf_err(struct iperf_test *t, const char *format, ...);
char *iperf_strerror(int);
extern int i_errno;
.fi
This is not a complete list of the available calls.
See the include file for more.
.SH EXAMPLES
Here's some sample code that runs an iperf client:
.nf
struct iperf_test *test;
test = iperf_new_test();
if ( test == NULL ) {
fprintf( stderr, "%s: failed to create test\n", argv0 );
exit( EXIT_FAILURE );
}
iperf_defaults( test );
iperf_set_test_role( test, 'c' );
iperf_set_test_server_hostname( test, host );
iperf_set_test_server_port( test, port );
if ( iperf_run_client( test ) < 0 ) {
fprintf( stderr, "%s: error - %s\n", argv0, iperf_strerror( i_errno ) );
exit( EXIT_FAILURE );
}
iperf_free_test( test );
.fi
And here's a server:
.nf
struct iperf_test *test;
test = iperf_new_test();
if ( test == NULL ) {
fprintf( stderr, "%s: failed to create test\n", argv0 );
exit( EXIT_FAILURE );
}
iperf_defaults( test );
iperf_set_test_role( test, 's' );
iperf_set_test_server_port( test, port );
for (;;) {
if ( iperf_run_server( test ) < 0 )
fprintf( stderr, "%s: error - %s\n\n", argv0, iperf_strerror( i_errn
o ) );
iperf_reset_test( test );
}
iperf_free_test( test );
.fi
These are not complete programs, just excerpts.
The full runnable source code can be found in the examples subdirectory
of the iperf3 source tree.

#ifndef _SYS_QUEUE_H_
#define _SYS_QUEUE_H_
/*
* This file defines five types of data structures: singly-linked lists,
* lists, simple queues, tail queues, and circular queues.
*
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A simple queue is headed by a pair of pointers, one the head of the
* list and the other to the tail of the list. The elements are singly
* linked to save space, so elements can only be removed from the
* head of the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the
* list. A simple queue may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.
