Merge branch 'modular-load'
Introduces a new configuration file layout. strongswan.conf is now only very simple and mainly includes the config snippets from the strongswan.d and strongswan.d/charon directories (the latter containing snippets for individual plugins). Config snippets with commented defaults are generated for all currently defined settings and are installed if they don't exist yet and the respective plugin/component is enabled. Similarly, the strongswan.conf(5) man page, which documents all these settings, is automatically generated from the same source. The config snippets are also installed in $prefix/share/strongswan so existing files can be compared to the most current defaults. As an alternative to the non-extensible charon.load option, the plugins to load can now be determined via the respective charon.plugins.<name>.load setting. This functionality is enabled by the new default strongswan.conf file (via the charon.load_modular option) and the load setting in the generated config snippets of all enabled plugins. The load setting optionally takes a numeric priority value that allows reordering the plugins (plugins with the same priority are ordered according to the default plugin order). Additionally, all settings that were formerly defined in library specific "global" sections are now application specific. For instance, instead of configuring libstrongswan.plugins.random.random and affecting charon, charon-cmd, pki, basically every application using libstrongswan, the option can now be set individually for each application (e.g. pki.plugins.random.random to affect only pki). The old options are still supported though, which actually allows to define defaults for all applications in the libstrongswan section. The libtls options are mapped to <app>.tls. The libimcv and libtnccs options are mapped to <app>.imcv and <app>.tnc, respectively (while their plugin's options are now under <app>.plugins together with all the others). Fixes #475.

|

Parses strongswan.conf option descriptions and produces configuration file
|
||||
and man page snippets.
|
||||
|
||||
The format for description files is as follows:
|
||||
|
||||
full.option.name [[:]= default]
|
||||
Short description intended as comment in config snippet
|
||||
|
||||
Long description for use in the man page, with
|
||||
simple formatting: _italic_, **bold**
|
||||
|
||||
Second paragraph of the long description
|
||||
|
||||
The descriptions must be indented by tabs or spaces but are both optional.
|
||||
If only a short description is given it is used for both intended usages.
|
||||
Line breaks within a paragraph of the long description or the short description
|
||||
are not preserved. But multiple paragraphs will be separated in the man page.
|
||||
Any formatting in the short description is removed when producing config
|
||||
snippets.
|
||||
|
||||
Options for which a value is assigned with := are not commented out in the
|
||||
produced configuration file snippet. This allows to override a default value,
|
||||
that e.g. has to be preserved for legacy reasons, in the generated default
|
||||
config.
|
||||
|
||||
To describe sections the following format can be used:
|
||||
|
||||
full.section.name {[#]}
|
||||
Short description of this section
|
||||
|
||||
Long description as above
|
||||
|
||||
If a # is added between the curly braces the section header will be commented
|
||||
out in the configuration file snippet, which is useful for example sections.

.SH DESCRIPTION
|
||||
While the
|
||||
.IR ipsec.conf (5)
|
||||
configuration file is well suited to define IPsec related configuration
|
||||
parameters, it is not useful for other strongSwan applications to read options
|
||||
from this file.
|
||||
The file is hard to parse and only
|
||||
.I ipsec starter
|
||||
is capable of doing so. As the number of components of the strongSwan project
|
||||
is continually growing, a more flexible configuration file was needed, one that
|
||||
is easy to extend and can be used by all components. With strongSwan 4.2.1
|
||||
.IR strongswan.conf (5)
|
||||
was introduced which meets these requirements.
|
||||
|
||||
.SH SYNTAX
|
||||
The format of the strongswan.conf file consists of hierarchical
|
||||
.B sections
|
||||
and a list of
|
||||
.B key/value pairs
|
||||
in each section. Each section has a name, followed by C-Style curly brackets
|
||||
defining the section body. Each section body contains a set of subsections
|
||||
and key/value pairs:
|
||||
.PP
|
||||
.EX
|
||||
settings := (section|keyvalue)*
|
||||
section := name { settings }
|
||||
keyvalue := key = value\\n
|
||||
.EE
|
||||
.PP
|
||||
Values must be terminated by a newline.
|
||||
.PP
|
||||
Comments are possible using the \fB#\fP-character, but be careful: The parser
|
||||
implementation is currently limited and does not like brackets in comments.
|
||||
.PP
|
||||
Section names and keys may contain any printable character except:
|
||||
.PP
|
||||
.EX
|
||||
. { } # \\n \\t space
|
||||
.EE
|
||||
.PP
|
||||
An example file in this format might look like this:
|
||||
.PP
|
||||
.EX
|
||||
a = b
|
||||
section-one {
|
||||
somevalue = asdf
|
||||
subsection {
|
||||
othervalue = xxx
|
||||
}
|
||||

|
||||
x = 12
|
||||
}
|
||||
.EE
|
||||
.PP
|
||||
Indentation is optional, you may use tabs or spaces.
|
||||
|
||||
.SH INCLUDING FILES
|
||||
Using the
|
||||
.B include
|
||||
statement it is possible to include other files into strongswan.conf, e.g.
|
||||
.PP
|
||||
.EX
|
||||
include /some/path/*.conf
|
||||
.EE
|
||||
.PP
|
||||
If the file name is not an absolute path, it is considered to be relative
|
||||
to the directory of the file containing the include statement. The file name
|
||||
may include shell wildcards (see
|
||||
.IR sh (1)).
|
||||
Also, such inclusions can be nested.
|
||||
.PP
|
||||
Sections loaded from included files
|
||||
.I extend
|
||||
previously loaded sections; already existing values are
|
||||
.IR replaced .
|
||||
It is important to note that settings are added relative to the section the
|
||||
include statement is in.
|
||||
.PP
|
||||
As an example, the following three files result in the same final
|
||||
config as the one given above:
|
||||
.PP
|
||||
.EX
|
||||
a = b
|
||||
section-one {
|
||||
somevalue = before include
|
||||
include include.conf
|
||||
}
|
||||
include other.conf
|
||||
|
||||
include.conf:
|
||||
# settings loaded from this file are added to section-one
|
||||
# the following replaces the previous value
|
||||
somevalue = asdf
|
||||
subsection {
|
||||
othervalue = yyy
|
||||
}
|
||||
yetanother = zz
|
||||
|
||||
other.conf:
|
||||
# this extends section-one and subsection
|
||||
section-one {
|
||||
subsection {
|
||||
# this replaces the previous value
|
||||
othervalue = xxx
|

}

}
|
||||
section-two {
|
||||
x = 12
|
||||
}
|
||||
.EE
|
||||
|
||||
.SH READING VALUES
|
||||
Values are accessed using a dot-separated section list and a key.
|
||||
With reference to the example above, accessing
|
||||
.B section-one.subsection.othervalue
|
||||
will return
|
||||
.BR xxx .
|
||||
|
||||
.SH DEFINED KEYS
|

The following keys are currently defined (using dot notation). The default
|
||||

section. To log to the console the two special filenames
|

.BR stdout " and " stderr
|
||||
can be used.
|
||||
.TP
|
||||
.B Syslog loggers
|
||||
Log into a syslog facility and are defined by specifying the facility to log to
|
||||
as the name of a subsection in the

||||
.B charon.syslog
|
||||
section. The following facilities are currently supported:
|
||||
.BR daemon " and " auth .
|

.SH JOB PRIORITY MANAGEMENT
|
||||
Some operations in the IKEv2 daemon charon are currently implemented
|
||||
synchronously and blocking. Two examples for such operations are communication
|
||||
with a RADIUS server via EAP-RADIUS, or fetching CRL/OCSP information during
|
||||
certificate chain verification. Under high load conditions, the thread pool may
|
||||
run out of available threads, and some more important jobs, such as liveness
|
||||
checking, may not get executed in time.
|
||||
.PP
|
||||
To prevent thread starvation in such situations job priorities were introduced.
|
||||
The job processor will reserve some threads for higher priority jobs, these
|
||||
threads are not available for lower priority, locking jobs.
|
||||
.SS Implementation
|
||||
Currently 4 priorities have been defined, and they are used in charon as
|
||||
follows:
|
||||
.TP
|
||||
.B CRITICAL
|
||||
Priority for long-running dispatcher jobs.
|
||||
.TP
|
||||
.B HIGH
|
||||
INFORMATIONAL exchanges, as used by liveness checking (DPD).
|
||||
.TP
|
||||
.B MEDIUM
|
||||
Everything not HIGH/LOW, including IKE_SA_INIT processing.
|
||||
.TP
|
||||
.B LOW
|
||||
IKE_AUTH message processing. RADIUS and CRL fetching block here
|
||||
.PP
|
||||
Although IKE_SA_INIT processing is computationally expensive, it is explicitly
|
||||
assigned to the MEDIUM class. This allows charon to do the DH exchange while
|
||||
other threads are blocked in IKE_AUTH. To prevent the daemon from accepting more
|
||||
IKE_SA_INIT requests than it can handle, use IKE_SA_INIT DROPPING.
|
||||
.PP
|
||||
The thread pool processes jobs strictly by priority, meaning it will consume all
|
||||
higher priority jobs before looking for ones with lower priority. Further, it
|
||||
reserves threads for certain priorities. A priority class having reserved
|
||||
.I n
|
||||
threads will always have
|
||||
.I n
|
||||
threads available for this class (either currently processing a job, or waiting
|
||||
for one).
|
||||
.SS Configuration
|
||||
To ensure that there are always enough threads available for higher priority
|
||||
tasks, threads must be reserved for each priority class.
|
||||
.TP
|
||||
.BR charon.processor.priority_threads.critical " [0]"
|
||||
Threads reserved for CRITICAL priority class jobs
|
||||
.TP
|
||||
.BR charon.processor.priority_threads.high " [0]"
|
||||
Threads reserved for HIGH priority class jobs
|
||||
.TP
|
||||
.BR charon.processor.priority_threads.medium " [0]"
|
||||
Threads reserved for MEDIUM priority class jobs
|
||||
.TP
|
||||
.BR charon.processor.priority_threads.low " [0]"
|
||||
Threads reserved for LOW priority class jobs
|
||||
.PP
|
||||
Let's consider the following configuration:
|
||||
.PP
|
||||
.EX
|
||||
charon {
|
||||
processor {
|
||||
priority_threads {
|
||||
high = 1
|
||||
medium = 4
|
||||
}
|
||||
}
|
||||
}
|
||||
.EE
|
||||
.PP
|
||||
With this configuration, one thread is reserved for HIGH priority tasks. As
|
||||
currently only liveness checking and stroke message processing is done with
|
||||
high priority, one or two threads should be sufficient.
|
||||
.PP
|
||||
The MEDIUM class mostly processes non-blocking jobs. Unless your setup is
|
||||
experiencing many blocks in locks while accessing shared resources, threads for
|
||||
one or two times the number of CPU cores is fine.
|
||||
.PP
|
||||
It is usually not required to reserve threads for CRITICAL jobs. Jobs in this
|
||||
class rarely return and do not release their thread to the pool.
|
||||
.PP
|
||||
The remaining threads are available for LOW priority jobs. Reserving threads
|
||||
does not make sense (until we have an even lower priority).
|
||||
.SS Monitoring
|
||||
To see what the threads are actually doing, invoke
|
||||
.IR "ipsec statusall" .
|
||||
Under high load, something like this will show up:
|
||||
.PP
|
||||
.EX
|
||||
worker threads: 2 or 32 idle, 5/1/2/22 working,
|
||||
job queue: 0/0/1/149, scheduled: 198
|
||||
.EE
|
||||
.PP
|
||||
From 32 worker threads,
|
||||
.IP 2
|
||||
are currently idle.
|
||||
.IP 5
|
||||
are running CRITICAL priority jobs (dispatching from sockets, etc.).
|
||||
.IP 1
|
||||
is currently handling a HIGH priority job. This is actually the thread currently
|
||||
providing this information via stroke.
|
||||
.IP 2
|
||||
are handling MEDIUM priority jobs, likely IKE_SA_INIT or CREATE_CHILD_SA
|
||||
messages.
|
||||
.IP 22
|
||||
are handling LOW priority jobs, probably waiting for an EAP-RADIUS response
|
||||
while processing IKE_AUTH messages.
|
||||
.PP
|
||||
The job queue load shows how many jobs are queued for each priority, ready for
|
||||
execution. The single MEDIUM priority job will get executed immediately, as
|
||||
we have two spare threads reserved for MEDIUM class jobs.
|
||||
|
||||
.SH IKE_SA_INIT DROPPING
|
||||
If a responder receives more connection requests per seconds than it can handle,
|
||||
it does not make sense to accept more IKE_SA_INIT messages. And if they are
|
||||
queued but can't get processed in time, an answer might be sent after the
|
||||
client has already given up and restarted its connection setup. This
|
||||
additionally increases the load on the responder.
|
||||
.PP
|
||||
To limit the responder load resulting from new connection attempts, the daemon
|
||||
can drop IKE_SA_INIT messages just after reception. There are two mechanisms to
|
||||
decide if this should happen, configured with the following options:
|
||||
.TP
|
||||
.BR charon.init_limit_half_open " [0]"
|
||||
Limit based on the number of half open IKE_SAs. Half open IKE_SAs are SAs in
|
||||
connecting state, but not yet established.
|
||||
.TP
|
||||
.BR charon.init_limit_job_load " [0]"
|
||||
Limit based on the number of jobs currently queued for processing (sum over all
|
||||
job priorities).
|
||||
.PP
|
||||
The second limit includes load from other jobs, such as rekeying. Choosing a
|
||||
good value is difficult and depends on the hardware and expected load.
|
||||
.PP
|
||||
The first limit is simpler to calculate, but includes the load from new
|
||||
connections only. If your responder is capable of negotiating 100 tunnels/s, you
|
||||
might set this limit to 1000. The daemon will then drop new connection attempts
|
||||
if generating a response would require more than 10 seconds. If you are
|
||||
allowing for a maximum response time of more than 30 seconds, consider adjusting
|
||||
the timeout for connecting IKE_SAs
|
||||
.RB ( charon.half_open_timeout ).
|
||||
A responder, by default, deletes an IKE_SA if the initiator does not establish
|
||||
it within 30 seconds. Under high load, a higher value might be required.
|
||||
|
||||
.SH LOAD TESTS
|
||||
To do stability testing and performance optimizations, the IKE daemon charon
|
||||
provides the \fIload-tester\fR plugin. This plugin allows one to setup thousands
|
||||
of tunnels concurrently against the daemon itself or a remote host.
|
||||
.PP
|
||||
.B WARNING:
|
||||
Never enable the load-testing plugin on productive systems. It provides
|
||||
preconfigured credentials and allows an attacker to authenticate as any user.
|
||||
.PP
|
||||
.SS Configuration details
|
||||
For public key authentication, the responder uses the
|
||||
.B \(dqCN=srv, OU=load-test, O=strongSwan\(dq
|
||||
identity. For the initiator, each connection attempt uses a different identity
|
||||
in the form
|
||||
.BR "\(dqCN=c1-r1, OU=load-test, O=strongSwan\(dq" ,
|
||||
where the first number inidicates the client number, the second the
|
||||
authentication round (if multiple authentication rounds are used).
|
||||
.PP
|
||||
For PSK authentication, FQDN identities are used. The server uses
|
||||
.BR srv.strongswan.org ,
|
||||
the client uses an identity in the form
|
||||
.BR c1-r1.strongswan.org .
|
||||
.PP
|
||||
For EAP authentication, the client uses a NAI in the form
|
||||
.BR [email protected] .
|
||||
.PP
|
||||
To configure multiple authentication rounds, concatenate multiple methods using,
|
||||
e.g.
|
||||
.EX
|
||||
initiator_auth = pubkey|psk|eap-md5|eap-aka
|
||||
.EE
|
||||
.PP
|
||||
The responder uses a hardcoded certificate based on a 1024-bit RSA key.
|
||||
This certificate additionally serves as CA certificate. A peer uses the same
|
||||
private key, but generates client certificates on demand signed by the CA
|
||||
certificate. Install the Responder/CA certificate on the remote host to
|
||||
authenticate all clients.
|
||||
.PP
|
||||
To speed up testing, the load tester plugin implements a special Diffie-Hellman
|
||||
implementation called \fImodpnull\fR. By setting
|
||||
.EX
|
||||
proposal = aes128-sha1-modpnull
|
||||
.EE
|
||||
this wicked fast DH implementation is used. It does not provide any security
|
||||
at all, but allows one to run tests without DH calculation overhead.
|
||||
.SS Examples
|
||||
.PP
|
||||
In the simplest case, the daemon initiates IKE_SAs against itself using the
|
||||
loopback interface. This will actually establish double the number of IKE_SAs,
|
||||
as the daemon is initiator and responder for each IKE_SA at the same time.
|
||||
Installation of IPsec SAs would fail, as each SA gets installed twice. To
|
||||
simulate the correct behavior, a fake kernel interface can be enabled which does
|
||||
not install the IPsec SAs at the kernel level.
|
||||
.PP
|
||||
A simple loopback configuration might look like this:
|
||||
.PP
|
||||
.EX
|
||||
charon {
|
||||
# create new IKE_SAs for each CHILD_SA to simulate
|
||||
# different clients
|
||||
reuse_ikesa = no
|
||||
# turn off denial of service protection
|
||||
dos_protection = no
|
||||
|
||||
plugins {
|
||||
load-tester {
|
||||
# enable the plugin
|
||||
enable = yes
|
||||
# use 4 threads to initiate connections
|
||||
# simultaneously
|
||||
initiators = 4
|
||||
# each thread initiates 1000 connections
|
||||
iterations = 1000
|
||||
# delay each initiation in each thread by 20ms
|
||||
delay = 20
|
||||
# enable the fake kernel interface to
|
||||
# avoid SA conflicts
|
||||
fake_kernel = yes
|
||||
}
|
||||
}
|
||||
}
|
||||
.EE
|
||||
.PP
|
||||
This will initiate 4000 IKE_SAs within 20 seconds. You may increase the delay
|
||||
value if your box can not handle that much load, or decrease it to put more
|
||||
load on it. If the daemon starts retransmitting messages your box probably can
|
||||
not handle all connection attempts.
|
||||
.PP
|
||||
The plugin also allows one to test against a remote host. This might help to
|
||||
test against a real world configuration. A connection setup to do stress
|
||||

.EX
|

relative timeout = retransmit_timeout * retransmit_base ^ (n-1)
|

Where
