It defines - objects which allow a network manager to instruct an agent - to test an interface for various faults. Tests for an - interface are defined in the media-specific MIB for that - interface. After invoking a test, the object ifTestResult - can be read to determine the outcome. If an agent can not - perform the test, ifTestResult is set to so indicate. The - object ifTestCode can be used to provide further test- - specific or interface-specific (or even enterprise-specific) - information concerning the outcome of the test. Only one - test can be in progress on each interface at any one time. - If one test is in progress when another test is invoked, the - second test is rejected. Some agents may reject a test when - a prior test is active on another interface. - - Before starting a test, a manager-station must first obtain - 'ownership' of the entry in the ifTestTable for the - interface to be tested. This is accomplished with the - ifTestId and ifTestStatus objects as follows: - - try_again: - get (ifTestId, ifTestStatus) - while (ifTestStatus != notInUse) - /* - * Loop while a test is running or some other - * manager is configuring a test. - */ - short delay - get (ifTestId, ifTestStatus) - } - - /* - * Is not being used right now -- let's compete - * to see who gets it. - */ - lock_value = ifTestId - - if ( set(ifTestId = lock_value, ifTestStatus = inUse, - - - ifTestOwner = 'my-IP-address') == FAILURE) - /* - * Another manager got the ifTestEntry -- go - * try again - */ - goto try_again; - - /* - * I have the lock - */ - set up any test parameters. - - /* - * This starts the test - */ - set(ifTestType = test_to_run); - - wait for test completion by polling ifTestResult - - when test completes, agent sets ifTestResult - agent also sets ifTestStatus = 'notInUse' - - retrieve any additional test results, and ifTestId - - if (ifTestId == lock_value+1) results are valid - - A manager station first retrieves the value of the - appropriate ifTestId and ifTestStatus objects, periodically - repeating the retrieval if necessary, until the value of - ifTestStatus is 'notInUse'. The manager station then tries - to set the same ifTestId object to the value it just - retrieved, the same ifTestStatus object to 'inUse', and the - corresponding ifTestOwner object to a value indicating - itself. If the set operation succeeds then the manager has - obtained ownership of the ifTestEntry, and the value of the - ifTestId object is incremented by the agent (per the - semantics of TestAndIncr). Failure of the set operation - indicates that some other manager has obtained ownership of - the ifTestEntry. - - Once ownership is obtained, any test parameters can be - setup, and then the test is initiated by setting ifTestType. - On completion of the test, the agent sets ifTestStatus to - 'notInUse'. Once this occurs, the manager can retrieve the - results. In the (rare) event that the invocation of tests - by two network managers were to overlap, then there would be - a possibility that the first test's results might be - overwritten by the second test's results prior to the first - - - results being read. This unlikely circumstance can be - detected by a network manager retrieving ifTestId at the - same time as retrieving the test results, and ensuring that - the results are for the desired request. - - If ifTestType is not set within an abnormally long period of - time after ownership is obtained, the agent should time-out - the manager, and reset the value of the ifTestStatus object - back to 'notInUse'. It is suggested that this time-out - period be 5 minutes. - - In general, a management station must not retransmit a - request to invoke a test for which it does not receive a - response; instead, it properly inspects an agent's MIB to - determine if the invocation was successful. Only if the - invocation was unsuccessful, is the invocation request - retransmitted. - - Some tests may require the interface to be taken off-line in - order to execute them, or may even require the agent to - reboot after completion of the test. In these - circumstances, communication with the management station - invoking the test may be lost until after completion of the - test. An agent is not required to support such tests. - However, if such tests are supported, then the agent should - make every effort to transmit a response to the request - which invoked the test prior to losing communication. When - the agent is restored to normal service, the results of the - test are properly made available in the appropriate objects. - Note that this requires that the ifIndex value assigned to - an interface must be unchanged even if the test causes a - reboot. An agent must reject any test for which it cannot, - perhaps due to resource constraints, make available at least - the minimum amount of information after that test - completes." - ::= { ifMIBObjects 3 } - -ifTestEntry OBJECT-TYPE - SYNTAX IfTestEntry - MAX-ACCESS not-accessible - STATUS deprecated - DESCRIPTION - "An entry containing objects for invoking tests on an - interface." - AUGMENTS { ifEntry } - ::= { ifTestTable 1 } - -IfTestEntry ::= - - - SEQUENCE { - ifTestId TestAndIncr, - ifTestStatus INTEGER, - ifTestType AutonomousType, - ifTestResult INTEGER, - ifTestCode OBJECT IDENTIFIER, - ifTestOwner OwnerString - } - -ifTestId OBJECT-TYPE - SYNTAX TestAndIncr - MAX-ACCESS read-write - STATUS deprecated - DESCRIPTION - "This object identifies the current invocation of the - interface's test." - ::= { ifTestEntry 1 } - -ifTestStatus OBJECT-TYPE - SYNTAX INTEGER { notInUse(1), inUse(2) } - MAX-ACCESS read-write - STATUS deprecated - DESCRIPTION - "This object indicates whether or not some manager currently - has the necessary 'ownership' required to invoke a test on - this interface.

That is, when queried, an existing conceptual row - has only three states: it is either available for use by - the managed device (the status column has value `active'); - it is not available for use by the managed device, though - the agent has sufficient information to attempt to make it - so (the status column has value `notInService'); or, it is - not available for use by the managed device, and an attempt - to make it so would fail because the agent has insufficient - information (the state column has value `notReady'). - - NOTE WELL - - This textual convention may be used for a MIB table, - irrespective of whether the values of that table's - conceptual rows are able to be modified while it is - active, or whether its conceptual rows must be taken - out of service in order to be modified. That is, it is - the responsibility of the DESCRIPTION clause of the - status column to specify whether the status column must - not be `active' in order for the value of some other - column of the same conceptual row to be modified. If - such a specification is made, affected columns may be - changed by an SNMP set PDU if the RowStatus would not - be equal to `active' either immediately before or after - processing the PDU. In other words, if the PDU also - contained a varbind that would change the RowStatus - value, the column in question may be changed if the - RowStatus was not equal to `active' as the PDU was - received, or if the varbind sets the status to a value - other than 'active'. - - - Also note that whenever any elements of a row exist, the - RowStatus column must also exist. - - To summarize the effect of having a conceptual row with a - status column having a SYNTAX clause value of RowStatus, - consider the following state diagram: - - - STATE - +--------------+-----------+-------------+------------- - | A | B | C | D - | |status col.|status column| - |status column | is | is |status column - ACTION |does not exist| notReady | notInService| is active ---------------+--------------+-----------+-------------+------------- -set status |noError ->D|inconsist- |inconsistent-|inconsistent- -column to | or | entValue| Value| Value -createAndGo |inconsistent- | | | - | Value| | | ---------------+--------------+-----------+-------------+------------- -set status |noError see 1|inconsist- |inconsistent-|inconsistent- -column to | or | entValue| Value| Value -createAndWait |wrongValue | | | ---------------+--------------+-----------+-------------+------------- -set status |inconsistent- |inconsist- |noError |noError -column to | Value| entValue| | -active | | | | - | | or | | - | | | | - | |see 2 ->D|see 8 ->D| ->D ---------------+--------------+-----------+-------------+------------- -set status |inconsistent- |inconsist- |noError |noError ->C -column to | Value| entValue| | -notInService | | | | - | | or | | or - | | | | - | |see 3 ->C| ->C|see 6 ---------------+--------------+-----------+-------------+------------- -set status |noError |noError |noError |noError ->A -column to | | | | or -destroy | ->A| ->A| ->A|see 7 ---------------+--------------+-----------+-------------+------------- -set any other |see 4 |noError |noError |see 5 -column to some| | | | -value | | see 1| ->C| ->D ---------------+--------------+-----------+-------------+------------- - - (1) goto B or C, depending on information available to the - agent. - - (2) if other variable bindings included in the same PDU, - provide values for all columns which are missing but - required, and all columns have acceptable values, then - return noError and goto D. - - (3) if other variable bindings included in the same PDU, - provide legal values for all columns which are missing but - required, then return noError and goto C. - - (4) at the discretion of the agent, the return value may be - either: - - inconsistentName: because the agent does not choose to - create such an instance when the corresponding - RowStatus instance does not exist, or - - inconsistentValue: if the supplied value is - inconsistent with the state of some other MIB object's - value, or - - noError: because the agent chooses to create the - instance. - - If noError is returned, then the instance of the status - column must also be created, and the new state is B or C, - depending on the information available to the agent. If - inconsistentName or inconsistentValue is returned, the row - remains in state A. - - (5) depending on the MIB definition for the column/table, - either noError or inconsistentValue may be returned. - - (6) the return value can indicate one of the following - errors: - - wrongValue: because the agent does not support - notInService (e.g., an agent which does not support - createAndWait), or - - inconsistentValue: because the agent is unable to take - the row out of service at this time, perhaps because it - is in use and cannot be de-activated. - - (7) the return value can indicate the following error: - - inconsistentValue: because the agent is unable to - remove the row at this time, perhaps because it is in - use and cannot be de-activated. - - (8) the transition to D can fail, e.g., if the values of the - conceptual row are inconsistent, then the error code would - be inconsistentValue. - - NOTE: Other processing of (this and other varbinds of) the - set request may result in a response other than noError - being returned, e.g., wrongValue, noCreation, etc. - - - Conceptual Row Creation - - There are four potential interactions when creating a - conceptual row: selecting an instance-identifier which is - not in use; creating the conceptual row; initializing any - objects for which the agent does not supply a default; and, - making the conceptual row available for use by the managed - device. - - Interaction 1: Selecting an Instance-Identifier - - The algorithm used to select an instance-identifier varies - for each conceptual row. In some cases, the instance- - identifier is semantically significant, e.g., the - destination address of a route, and a management station - selects the instance-identifier according to the semantics. - - In other cases, the instance-identifier is used solely to - distinguish conceptual rows, and a management station - without specific knowledge of the conceptual row might - examine the instances present in order to determine an - unused instance-identifier. (This approach may be used, but - it is often highly sub-optimal; however, it is also a - questionable practice for a naive management station to - attempt conceptual row creation.) - - Alternately, the MIB module which defines the conceptual row - might provide one or more objects which provide assistance - in determining an unused instance-identifier. For example, - if the conceptual row is indexed by an integer-value, then - an object having an integer-valued SYNTAX clause might be - defined for such a purpose, allowing a management station to - issue a management protocol retrieval operation. In order - to avoid unnecessary collisions between competing management - stations, `adjacent' retrievals of this object should be - different. - - Finally, the management station could select a pseudo-random - number to use as the index. In the event that this index - was already in use and an inconsistentValue was returned in - response to the management protocol set operation, the - management station should simply select a new pseudo-random - number and retry the operation. - - A MIB designer should choose between the two latter - algorithms based on the size of the table (and therefore the - efficiency of each algorithm). For tables in which a large - number of entries are expected, it is recommended that a MIB - object be defined that returns an acceptable index for - creation. For tables with small numbers of entries, it is - recommended that the latter pseudo-random index mechanism be - used. - - Interaction 2: Creating the Conceptual Row - - Once an unused instance-identifier has been selected, the - management station determines if it wishes to create and - activate the conceptual row in one transaction or in a - negotiated set of interactions. - - Interaction 2a: Creating and Activating the Conceptual Row - - The management station must first determine the column - requirements, i.e., it must determine those columns for - which it must or must not provide values. Depending on the - complexity of the table and the management station's - knowledge of the agent's capabilities, this determination - can be made locally by the management station. Alternately, - the management station issues a management protocol get - operation to examine all columns in the conceptual row that - it wishes to create. In response, for each column, there - are three possible outcomes: - - - a value is returned, indicating that some other - management station has already created this conceptual - row. We return to interaction 1. - - - the exception `noSuchInstance' is returned, - indicating that the agent implements the object-type - associated with this column, and that this column in at - least one conceptual row would be accessible in the MIB - view used by the retrieval were it to exist. For those - columns to which the agent provides read-create access, - the `noSuchInstance' exception tells the management - station that it should supply a value for this column - when the conceptual row is to be created. - - - the exception `noSuchObject' is returned, indicating - that the agent does not implement the object-type - associated with this column or that there is no - conceptual row for which this column would be - accessible in the MIB view used by the retrieval. As - such, the management station can not issue any - management protocol set operations to create an - instance of this column. - - Once the column requirements have been determined, a - management protocol set operation is accordingly issued. - This operation also sets the new instance of the status - column to `createAndGo'. - - When the agent processes the set operation, it verifies that - it has sufficient information to make the conceptual row - available for use by the managed device. The information - available to the agent is provided by two sources: the - management protocol set operation which creates the - conceptual row, and, implementation-specific defaults - supplied by the agent (note that an agent must provide - implementation-specific defaults for at least those objects - which it implements as read-only). If there is sufficient - information available, then the conceptual row is created, a - `noError' response is returned, the status column is set to - `active', and no further interactions are necessary (i.e., - interactions 3 and 4 are skipped). If there is insufficient - information, then the conceptual row is not created, and the - set operation fails with an error of `inconsistentValue'. - On this error, the management station can issue a management - protocol retrieval operation to determine if this was - because it failed to specify a value for a required column, - or, because the selected instance of the status column - already existed. In the latter case, we return to - interaction 1. In the former case, the management station - can re-issue the set operation with the additional - information, or begin interaction 2 again using - `createAndWait' in order to negotiate creation of the - conceptual row. - - NOTE WELL - - Regardless of the method used to determine the column - requirements, it is possible that the management - station might deem a column necessary when, in fact, - the agent will not allow that particular columnar - instance to be created or written. In this case, the - management protocol set operation will fail with an - error such as `noCreation' or `notWritable'. In this - case, the management station decides whether it needs - to be able to set a value for that particular columnar - instance. If not, the management station re-issues the - management protocol set operation, but without setting - a value for that particular columnar instance; - otherwise, the management station aborts the row - creation algorithm. - - Interaction 2b: Negotiating the Creation of the Conceptual - Row - - The management station issues a management protocol set - operation which sets the desired instance of the status - column to `createAndWait'. If the agent is unwilling to - process a request of this sort, the set operation fails with - an error of `wrongValue'. (As a consequence, such an agent - must be prepared to accept a single management protocol set - operation, i.e., interaction 2a above, containing all of the - columns indicated by its column requirements.) Otherwise, - the conceptual row is created, a `noError' response is - returned, and the status column is immediately set to either - `notInService' or `notReady', depending on whether it has - sufficient information to (attempt to) make the conceptual - row available for use by the managed device. If there is - sufficient information available, then the status column is - set to `notInService'; otherwise, if there is insufficient - information, then the status column is set to `notReady'. - Regardless, we proceed to interaction 3. - - Interaction 3: Initializing non-defaulted Objects - - The management station must now determine the column - requirements. It issues a management protocol get operation - to examine all columns in the created conceptual row. In - the response, for each column, there are three possible - outcomes: - - - a value is returned, indicating that the agent - implements the object-type associated with this column - and had sufficient information to provide a value. For - those columns to which the agent provides read-create - access (and for which the agent allows their values to - be changed after their creation), a value return tells - the management station that it may issue additional - management protocol set operations, if it desires, in - order to change the value associated with this column. - - - the exception `noSuchInstance' is returned, - indicating that the agent implements the object-type - associated with this column, and that this column in at - least one conceptual row would be accessible in the MIB - view used by the retrieval were it to exist. However, - the agent does not have sufficient information to - provide a value, and until a value is provided, the - conceptual row may not be made available for use by the - managed device. For those columns to which the agent - provides read-create access, the `noSuchInstance' - exception tells the management station that it must - issue additional management protocol set operations, in - order to provide a value associated with this column. - - - the exception `noSuchObject' is returned, indicating - that the agent does not implement the object-type - associated with this column or that there is no - conceptual row for which this column would be - accessible in the MIB view used by the retrieval. As - such, the management station can not issue any - management protocol set operations to create an - instance of this column. - - If the value associated with the status column is - `notReady', then the management station must first deal with - all `noSuchInstance' columns, if any. Having done so, the - value of the status column becomes `notInService', and we - proceed to interaction 4. - - Interaction 4: Making the Conceptual Row Available - - Once the management station is satisfied with the values - associated with the columns of the conceptual row, it issues - a management protocol set operation to set the status column - to `active'. If the agent has sufficient information to - make the conceptual row available for use by the managed - device, the management protocol set operation succeeds (a - `noError' response is returned). Otherwise, the management - protocol set operation fails with an error of - `inconsistentValue'. - - NOTE WELL - - A conceptual row having a status column with value - `notInService' or `notReady' is unavailable to the - managed device. As such, it is possible for the - managed device to create its own instances during the - time between the management protocol set operation - which sets the status column to `createAndWait' and the - management protocol set operation which sets the status - column to `active'. In this case, when the management - protocol set operation is issued to set the status - column to `active', the values held in the agent - supersede those used by the managed device. - - If the management station is prevented from setting the - status column to `active' (e.g., due to management station - or network failure) the conceptual row will be left in the - `notInService' or `notReady' state, consuming resources - indefinitely. The agent must detect conceptual rows that - have been in either state for an abnormally long period of - time and remove them. It is the responsibility of the - DESCRIPTION clause of the status column to indicate what an - abnormally long period of time would be. This period of - time should be long enough to allow for human response time - (including `think time') between the creation of the - conceptual row and the setting of the status to `active'. - In the absence of such information in the DESCRIPTION - clause, it is suggested that this period be approximately 5 - minutes in length. This removal action applies not only to - newly-created rows, but also to previously active rows which - are set to, and left in, the notInService state for a - prolonged period exceeding that which is considered normal - for such a conceptual row. - - Conceptual Row Suspension - - When a conceptual row is `active', the management station - may issue a management protocol set operation which sets the - instance of the status column to `notInService'. If the - agent is unwilling to do so, the set operation fails with an - error of `wrongValue' or `inconsistentValue'. Otherwise, - the conceptual row is taken out of service, and a `noError' - response is returned. It is the responsibility of the - DESCRIPTION clause of the status column to indicate under - what circumstances the status column should be taken out of - service (e.g., in order for the value of some other column - of the same conceptual row to be modified). - - - Conceptual Row Deletion - - For deletion of conceptual rows, a management protocol set - operation is issued which sets the instance of the status - column to `destroy'. This request may be made regardless of - the current value of the status column (e.g., it is possible - to delete conceptual rows which are either `notReady', - `notInService' or `active'.) If the operation succeeds, - then all instances associated with the conceptual row are - immediately removed." - SYNTAX INTEGER { - -- the following two values are states: - -- these values may be read or written - active(1), - notInService(2), - - -- the following value is a state: - -- this value may be read, but not written - notReady(3), - - -- the following three values are - -- actions: these values may be written, - -- but are never read - createAndGo(4), - createAndWait(5), - destroy(6) - } - -TimeStamp ::= TEXTUAL-CONVENTION - STATUS current - DESCRIPTION - "The value of the sysUpTime object at which a specific - occurrence happened.

It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16.

to be used from TCPIP thread) + * is an abstraction layer that prevents applications linking hard against the + * @ref tcp.h functions while providing the same functionality.

To minimize code changes + * in this case, the use of altcp_allocators is strongly suggested. + * + * Usage + * ----- + * To make use of this API from an existing tcp raw API application: + * * Include "lwip/altcp.h" instead of "lwip/tcp.h" + * * Replace "struct tcp_pcb" with "struct altcp_pcb" + * * Prefix all called tcp API functions with "altcp_" instead of "tcp_" to link + * against the altcp functions + * * @ref altcp_new (and @ref altcp_new_ip_type/@ref altcp_new_ip6) take + * an @ref altcp_allocator_t as an argument, whereas the original tcp API + * functions take no arguments. + * * An @ref altcp_allocator_t allocator is an object that holds a pointer to an + * allocator object and a corresponding state (e.g. for TLS, the corresponding + * state may hold certificates or keys). This way, the application does not + * even need to know if it uses TLS or pure TCP, this is handled at runtime + * by passing a specific allocator. + * * An application can alternatively bind hard to the altcp_tls API by calling + * @ref altcp_tls_new or @ref altcp_tls_wrap. + * * The TLS layer is not directly implemented by lwIP, but a port to mbedTLS is + * provided. + * * Another altcp layer is proxy-connect to use TLS behind a HTTP proxy (see + * @ref altcp_proxyconnect.h) + * + * altcp_allocator_t + * ----------------- + * An altcp allocator is created by the application by combining an allocator + * callback function and a corresponding state, e.g.:\code{.c} + * static const unsigned char cert[] = {0x2D, ...

However, the parameters used to create it are defined in @ref + * altcp_tls.h (see @ref altcp_tls_create_config_server_privkey_cert for servers + * and @ref altcp_tls_create_config_client/@ref altcp_tls_create_config_client_2wayauth + * for clients). + * + * For mbedTLS, ensure that certificates can be parsed by 'mbedtls_x509_crt_parse()' and + * private keys can be parsed by 'mbedtls_pk_parse_key()'. + */ + +/* + * Copyright (c) 2017 Simon Goldschmidt + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * + * 1.

An address scope can be either global or more constrained. + * In lwIP, we say that an address "has a scope" or "is scoped" when its scope + * is constrained, in which case the address is meaningful only in a specific + * "zone." For unicast addresses, only link-local addresses have a scope; in + * that case, the scope is the link. For multicast addresses, there are various + * scopes defined by RFC 4007 and others. For any constrained scope, a system + * must establish a (potentially one-to-many) mapping between zones and local + * interfaces. For example, a link-local address is valid on only one link (its + * zone). That link may be attached to one or more local interfaces. The + * decisions on which scopes are constrained and the mapping between zones and + * interfaces is together what we refer to as the "scoping policy" - more on + * this in a bit. + * + * In lwIP, each IPv6 address has an associated zone index. This zone index may + * be set to "no zone" (IP6_NO_ZONE, 0) or an actual zone. We say that an + * address "has a zone" or "is zoned" when its zone index is *not* set to "no + * zone." In lwIP, in principle, each address should be "properly zoned," which + * means that if the address has a zone if and only if has a scope. As such, it + * is a rule that an unscoped (e.g., global) address must never have a zone. + * Even though one could argue that there is always one zone even for global + * scopes, this rule exists for implementation simplicity. Violation of the + * rule will trigger assertions or otherwise result in undesired behavior. + * + * Backward compatibility prevents us from requiring that applications always + * provide properly zoned addresses. We do enforce the rule that the in the + * lwIP link layer (everything below netif->output_ip6() and in particular ND6) + * *all* addresses are properly zoned. Thus, on the output paths down the + * stack, various places deal with the case of addresses that lack a zone. + * Some of them are best-effort for efficiency (e.g. the PCB bind and connect + * API calls' attempts to add missing zones); ultimately the IPv6 output + * handler (@ref ip6_output_if_src) will set a zone if necessary. + * + * Aside from dealing with scoped addresses lacking a zone, a proper IPv6 + * implementation must also ensure that a packet with a scoped source and/or + * destination address does not leave its zone. This is currently implemented + * in the input and forward functions. However, for output, these checks are + * deliberately omitted in order to keep the implementation lightweight. The + * routing algorithm in @ref ip6_route will take decisions such that it will + * not cause zone violations unless the application sets bad addresses, though. + * + * In terms of scoping policy, lwIP implements the default policy from RFC 4007 + * using macros in this file. This policy considers link-local unicast + * addresses and (only) interface-local and link-local multicast addresses as + * having a scope. For all these addresses, the zone is equal to the interface. + * As shown below in this file, it is possible to implement a custom policy. + */ + +/* + * Copyright (c) 2017 The MINIX 3 Project. + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * + * 1.
