<li>For a better user experience, it is important to provide &lt;challenge/> fallbacks rather than directly fail with a &lt;failure/> on the first user error. <cite>XEP-0158</cite> for instance proposes to fail directly on a wrong answer to a CAPTCHA challenge, while it is well known that many actual human users regularly fails, sometimes even several, captchas before succeeding one. As a consequence, in such a case or other similar challenge, it is better to return a new challenge (a new CAPTCHA for instance) rather than cancelling the negotiation, doing so eventually only after a few retries.</li>
<li>The storage mechanism does not mean necessarily that credentials have to be stored in the given form, in particular when the server estimates a storage mechanism being stronger than the one desired by the user, and still without losing any authentication possibility. For instance if a client was to exchange credentials in PLAIN, and if the server usually provides SCRAM-SHA1, SCRAM-SHA-256 and PLAIN authentication mechanisms, then it would be wise to store it as both SCRAM-SHA-1 and SCRAM-SHA-256 instead of PLAIN. This way the security of the password is highly renforced in the case of the database being stolen and the three authentication mechanisms are still available to this user. Of course it would have been even more secure for the client itself to exchange the credentials as SCRAM-SHA-1 and SCRAM-SHA-256 from the start, because by exchanging PLAIN data, possibility is given to a man-in-the-middle attack to steal directly the password during this one-time account registration.</li>
<li>Security may have a price. If you were to store credentials with SCRAM-SHA-256 only, and later you change to a client which supports only PLAIN and SCRAM-SHA-1, you may fall in a case where you force yourself to log in using PLAIN. For this reason, a good client implementation SHOULD be able to determine such edge case. In the previous case, if possible, it SHOULD have stored both SCRAM-SHA-1 and SCRAM-SHA-256 on registration or silently modify later its storage.</li>
<li>When registering a new account, considering that the user has obviously not been authenticated yet, the server MUST NOT rely on the 'from' value of the initiating stream. In particular:</li>
<li>When registering a new account, considering that the user has obviously not been authenticated yet, the server MUST NOT rely on the 'from' value of the initiating stream. In particular:
<ul>
<li>the server MUST NOT decide whether or not to propose the &lt;registration/> feature based on the existence of the JID filled in 'from'. Doing so would leak away information about the existence of a JID which could therefore be sent undesirable messages. Being consistent on showing the feature forces to try to register which can already eliminates part of the risk if the challenge provides some bot protection (for instance CAPTCHAs).
<br />A perfectly valid alternative would be to always provide the &lt;registration/> feature when no "from" is filled but never provide it when a "from is filled" (no matter it is an existing JID or not). This consistent logics does not leak information.</li>
<li>Do not modify the SASL authentication's mechanisms listed in the &lt;mechanisms/> feature depending on the 'from'. Even though a given JID might not be able to connect with some mechanisms because the credentials storage is incompatible, this would leak information on the kind of storage mechanism used for this user. This information would allow attackers to determine, then target, users whose storage would be weaker.
<br/>Of course this particular point might cause issues for users regularly changing their clients or log in from various computer. For instance the SCRAM-SHA-1 and SCRAM-SHA-256 storage are incompatible. If you first registered by specifying the SCRAM-SHA-256 storage, then on another client which does not support SCRAM-SHA-256 or even who supports it, but for some reason always try and gives priority to SCRAM-SHA-1, the user could be found in a situation where he never manages to authenticate while providing the right password. For this reason, it could be wiser for server deployments to choose compatible mechanisms, when possible. On client side, if they are provided a raw password, instead of pre-computed data for a specific mechanism, then they should intelligently try the various mechanisms, starting from the one they consider the stronger. Hence try SCRAM-SHA-256, then SCRAM-SHA-1 if the first failed, then only if both failed, tell the user that authentication failed (note that the client should not try PLAIN as a last fallback, because we remind that any SCRAM-* storage is compatible with the SASL PLAIN mechanism. Trying PLAIN would therefore be a security risk.</li>

Linked Process is a protocol for Internet-scale, general-purpose distributed computing. With an implementation of this protocol, any computing device with an Internet connection can contribute computing resources to a user-generated compute cloud.
</p>
<ul>
<li>The term <strong>computing device</strong> is broad and spans particulars such as cell phones, laptops, desktops, servers, supercomputers, etc. In Linked Process, a computing device is anything that maintains a central processing unit (CPU) that can be programmed to execute any desired computation.</li>
<li>The term <strong>computing resources</strong> is broad and spans particulars such as clock cycles, data sets, software application programming interfaces (APIs), or specialized hardware componets such as cell phone cameras, field-programmable gate array (FPGA) circuits, etc.</li>
<li>The term <strong>compute cloud</strong> is the collection of all Linked Process enabled devices, their resources, and the Linked Process specific software components defined later in this specification.</li>
</ul>
</p>
<p>
Within the category of computing devices, Linked Process makes a distinction between resource consumers (devices making use of non-local computing resources) and a resource providers (devices offering computing resources)<note>Nothing prevents the same device from being a resource consumer in one context and being a resource provider in another.</note>. Linked Process allows a resource consumer to leverage the computing resources offered by a resource provider in anyway deemed appropriate by the resource consumer. This is accomplished by the resource consumer providing/migrating/sending code (i.e. software instructions) to a computer language interpreter maintained by the resource provider. As such, it is up to the resource consumer to define the instructions to be executed by the provider. Given this architecture, resource providing devices in a Linked Process cloud are general-purpose computing sandboxes (i.e. they can be leveraged for computational ends that are defined by a resource consumer).

Linked Process was developed to address the following two distributed computing requirements: <em>Internet-scale</em> and <em>general-purpose</em>. These requirements imply yet more requirements which accompany their description below.
</p>
<ul>
<li><strong>Internet-scale</strong>: it is required that any device with an Internet connection (from a cell phone to a supercomputer) be able provide/contribute and consume/leverage computing resources in a Linked Process cloud.</li>
<li><strong>Internet-scale</strong>: it is required that any device with an Internet connection (from a cell phone to a supercomputer) be able provide/contribute and consume/leverage computing resources in a Linked Process cloud.
<ul>
<li><strong>Decentralized</strong>: it is required that the computing resources are not necessarily centralized or controlled by any one party.</li>
<li><strong>Discoverable</strong>: it is required that resource providers be discoverable by resources consumers.</li>
<li><strong>Transient</strong>: it is required that devices coming online and offline are gracefully incoporated and removed from the cloud.</li>

<li><strong>General-purpose</strong>: It is required that consumers be able to utilize provided resources for any desired purpose.</li>
</ul></li>
<li><strong>General-purpose</strong>: It is required that consumers be able to utilize provided resources for any desired purpose.
<ul>
<li><strong>Language-agnostic</strong>: it is required that the protocol support the migration of code written in any computer language.</li>
<li><strong>Safe</strong>: it is required that the execution of consumer code be confined by permissions clearly specified by the resource provider<note>There is a tradeoff between "general-purpose" and "safety." It is important to ensure that the integrity of resource providers are not compomised due to malicious or poorly written code.</note>.</li>
<li><strong>Accessible</strong>: it is required that computing resources be accessible when permissions allow by ensuring the supported language interpreters provide necessary "low-level" manipulations of such resources.</li>

A <tt>&lt;spawn_vm/&gt;</tt> element is wrapped by an <tt>&lt;iq/&gt;</tt> element. The purpose of <tt>&lt;spawn_vm/&gt;</tt> is to have a farm create a new virtual machine. It is through a virtual machine that a villein is able to access the computing resources of the physical device that hosts the farm (i.e. the resource provider). A virtual machine will maintain a state throughout a villein "session" with that virtual machine. The only way to alter the state of a virtual machine is through submitting jobs and updating its variable bindings<note>This is an important concept to understand. During the life of a virtual machine, the virtual machine has a state that changes as jobs are submitted and bindings are managed. In other words, a virtual machine is not a "one-job" machine.</note>.

<p>As with anything, there are no hard and fast rules. If there were, they might look like these. First, for devices:</p>
<dl>
<dt>Transmit no data.</dt>
<dd>Transmitting costs significant power, and moreover raises the radio state. Not transmitting will allow it to maximize the time spent in the low-cost Idle state.</dd>
<dt>If you must transmit, then transmit only a small volume.</dt>
<dd>If there is only a small amount of data transmitted - less than 128 octets typically - the radio will only raise to FACH, which is significantly cheaper than DCH.</dd>
<dt>If you must transmit, then compress as hard as possible.</dt>
<dd>Since individual octets have an associate power - and often financial - cost, it's worth maximizing the compression algorithm, even if the volume of traffic will raise to DCH.</dd>
<dt>If you have transmit a lot, then do a lot</dt>
<dd>If the radio is raised to DCH anyway, then you may as well go fetch that avatar you were missing, since you're chewing through power anyway.</dd>
<dt>If you receive, then transmit</dt>
<dd>If your peer raises the radio state, you may as well use it.</dd>

<dl>
<dt>Send no data.</dt>
<dd>Sending data will cause the handset to be raised out of Idle. This immediately costs massively higher power.</dd>
<dt>If you must send, send tiny bits.</dt>
<dd>Sending small enough data maximizes the likelyhood that the devices radio will only be raised to FACH levels.</dd>
<dt>If you receive, then send anything you have.</dt>
<dd>Receiving data indicates that the radio is active - it'll stay active for some time, so sending data doesn't incur the overhead of raising the radio state, and won't increase power drain on the handset.</dd>
<dt>If you must send when not receiving, send plenty.</dt>
<dd>Sending data will raise the radio's state - unless you can tell this will only raise it to FACH, it's worth sending as much as possible.</dd>

<p>Finally, protocol designers should aim to minimize any responses required from the handset, and ensure keepalive traffic, if any, fits inside FACH wherever possible.</p>

<section1 topic='Introduction' anchor='intro'>
<p>While SASL provides an excellent framework that has served us well over the past 18 years, a number of shortcomings in the profile - the syntax binding to XMPP - that is in use.</p>
<p>This specification addresses a number of shortfalls:</p>
<ul>
<li>Number of round trips</li>
<li>Extensibility</li>
<li>Support for second factor</li>
<li>Support for mandatory password changes</li>
</ul>
<p>The new SASL profile documented herein is primarily a syntactic change to allow extensibility, combined with removal of the (largely) redundant stream restart, and additional results beyond total success or abject failure.</p>
<section2 topic="Terminology">
<p>Although initiating entities, in general, use SASL, and receiving entities offer it, the SASL specification and common parlance both use "Client " and "Server"; this specification uses Client and Server and assumes C2S links. This is not intended to preclude use of this SASL profile on S2S links. The term "SASL2" is used to mean the new SASL profile specified in this document; however the same RFC 4422 definition of SASL (and SASL profiles) applies.</p>
<p>Examples often use hypothetical SASL mechanisms and sub-extensions; this specification does not intend to make a position on any particular SASL mechanism, and the Mandatory To Implement mechanisms are unaffected.</p>
</section2>

<section1 topic='Overview' anchor="overview">
<section2 topic="Discovering Support" anchor="feature">
<p>Servers capable of SASL2 offer a stream feature of &lt;mechanisms/>, qualified by the "urn:xmpp:sasl:0" namespace. This in turn contains one or more &lt;mechanism/> elements in the same namespace, and potentially other elements (for example, the &lt;hostname/> element defined within XEP-0233).</p>
<p>Note that SASL2 is impossible for clients to initiate without at least one mechanism being available, and therefore MUST NOT be offered.</p>
<p>The feature so advertised, and its child content, SHOULD be stable for the given stream to and from attributes and encryption state, and therefore MAY be cached by clients for later connections.</p>
<p>The Service Name used by XMPP is unchanged from RFC 6120.</p>
</section2>
<section2 topic="SASL Data Encoding">
<p>In all cases, both Clients and Servers encode SASL exchanges using Base 64 encoding. This SHOULD NOT include any line wrapping or other whitespace. As the form &lt;element/> is equivalent to &lt;element>&lt;/element>, these both indicate an empty string, which is used to indicate no data (ie, the absence of the data). In order to explicitly transmit a zero-length SASL challenge or response, the sending party sends a single equals sign character ("=").</p>
</section2>
<section2 topic="Initiation">
<p>Clients, upon observing this stream feature, initiate the authentication by the use of the &lt;authenticate/> top-level element, within the same namespace. The nature of this element is to inform the server about properties of the final stream state, as well as initiate authentication itself. To achieve the latter, it has a single mandatory attribute of "mechanism", with a string value of a mechanism name offered by the Server in the stream feature, and an optional child element of &lt;initial-response/>, containing a base64-encoded SASL Initial Response.</p>
<p>On subsequent connections, if a Client has previously cache the stream feature, the Client MAY choose to send it before seeing the stream features - sending it "pipelined" with the Stream Open tag for example.</p>
<example caption="An authentication request"><![CDATA[

<initial-response>SW1wcm92ZWQgZW5jYXNwdWxhdGlvbiBvZiBvcHRpb25hbCBTQVNMLUlSIGRhdGE=</initial-response>
</authenticate>
]]>
</example>
<p>In order to provide support for other desired stream states beyond authentication, additional child elements are used. For example, a hypothetical XEP-0198 session resumption element might be included, and/or Resource Binding requests.</p>
<example caption="An authentication request with a (hypothetical) bind request"><![CDATA[

</section2>
<section2 topic="Challenges and Responses" anchor="challenge">
<p>Server Challenges MAY then be sent. Each Challenge MUST be responded to by a Client in a Client Response. These are not extensible, and contain the corresponding base64 encoded SASL data:</p>

]]>
</example>
</section2>
<section2 topic="During Authentication">
<p>At any time while authentication is in progress, neither Client nor Server sends any element (including stanzas) or other data except the top-level elements defined herein. Clients MUST NOT send whitespace, and MUST send only &lt;response/> elements as appropriate or an &lt;abort/> element to immediately cause an error. Servers MUST disconnect Clients immediately if any other traffic is received. Servers are similarly REQUIRED to send no whitespace, and only the &lt;response/> and completion elements from the section below.</p>
</section2>
<section2 topic="Completing Authentication">
<p>Authentication may complete in one of three ways. It may complete successfully, in which case the client is authenticated. It may also fail, in which case the client is not authenticated and the stream and session state remain entirely unchanged.</p>
<p>Finally, it may have completed successfully, but further interaction is required - for example, a password change or second-factor authentication.</p>
<section3 topic="Success">
<p>If the Client is now authenticated, the Server sends a &lt;success/> element, which contains an OPTIONAL &lt;additional-data/> element containing SASL additional data. It also contains a &lt;authorization-identity/> element containing the negotiated identity - this is a bare JID, unless resource binding has occurred, in which case it is a full JID.</p>
<example caption="Successful authentication"><![CDATA[

</section3>
<section3 topic="Failure">
<p>A &lt;failure/> element is used by the server to terminate the authentication attempt. It MAY contain application-specific error codes, and MAY contain a textual error. It MUST contain one of the SASL error codes from RFC 6120 Section 6.5.</p>
<example caption="Failure"><![CDATA[
<failure xmlns='urn:xmpp:sasl:0'>

</failure>
]]></example>
</section3>
<section3 topic="Continue" anchor="continue">
<p>A &lt;continue/> element is used to indicate that while the SASL exchange was successful, it is insufficient to allow authentication at this time.</p>
<p>This can be used to indicate that the Client needs to perform a Second Factor Authentication ("2FA"), or is required to change password. These are conducted as additional SASL mechanisms. Such SASL mechanisms MUST NOT change the authorization identifier, or introduce any security layer. The authorization identifer transmitted during the subsequent &lt;success/>, and any security layer which comes into effect after the eventual &lt;success/>, therefore MUST be that of the first mechanism.</p>
<p>The element contains a &lt;mechanisms/> element, as defined above as a stream feature, containing suitable mechanisms. It MAY contain an &lt;additional-data/> element, as the &lt;success/> element does.</p>
<p>Finally, it MAY contain a &lt;text/> element, which can contain human-readable data explaining the nature of the step required.</p>

Service administrators might want to deploy server-based spim recognition software to fill in the gaps. However, every automated spim recognition suffers from <em>false positives</em> - situations where a stanza incorrectly qualified as spim. To avoid them, a spim filter doesn't block suspicious stanza, but marks it and sends to a client in a regular manner. A client software doesn't need to interrupt a user when processing such marked stanzas: for example, it may put them silently in "SPAM" folder, so a user can look through them at any time later. Furthermore, a spim filter may take user's experience into account. When a user receives an unsolicited stanza, he or she can mark it as spim. In this case a client software sends an automatic complaint to a server-based spim filter. This specification deals with both cases. Thus, in contrast to &xep0159;, it doesn't introduce any spim blocking techniques. Also, the various spim recognition procedures that may be employed by the server are beyond the scope of this document.
