repos_ecs/Snmp/snmp++/CHANGES.snmp++v3

Changes snmp++v3.2.23
=====================

- Fixed: SNMPv3 message id creation was not thread safe.
- Added: IPv6 utility functions to allow IPv6 for VC++
  compiler (Ragavan Tetchinamourty).
- Fixed: Key change algorithm now works for keys longer than
  16 bytes.
- Fixed: ASN parse error on 64 bit platforms.
- Improved: Address classes can now handle IPv6 scope id.
  Length defines for IPv6 have been renamed, see address.h
  for new names if you get compile errors.
- Fixed: With IPv6 disabled, transport errors could trigger IPv6
  related warning.

Changes snmp++v3.2.22
=====================

- Fixed: After a CTarget::clear() get_type() returned type_base
  instead of type_ctarget (Lior Klibansky).
- Fixed: The message id could be negative if engine boots is
  greater than 0x7fff. (Wai-Kiong Choy)
- Fixed: Removed lots of compiler warnings (-Wcast-qual, -Wshadow),
  unused code, and other things (Jeremy Nimmer)
- Added: User defined log class USER_LOG.
- Fixed: Thread handle was not closed on Snmp::stop_poll_thread() on
  WIN32 platform. (found from Stoyan Haralampiev).
- Fixed: Possible deadlock after a call to Snmp::engine_id_discovery().
- Fixed: debughexprintf() did not print the last output line.
- Fixed: Check for duplicate entries in engine id table.
- Fixed: Don't allow SNMP INFORM over SNMPv1.
- Fixed: If a SNMPv3 response was received from a different address/port
  than the request was sent to, no valid mapping address/port <-> enigne id
  was stored, so no communication was possible.

Changes snmp++v3.2.21
=====================

- Added: New overloeaded Oid::set_data() that takes a char array instead
  of ulong array.
- Fixed: The dotted oid string parser no longer accepts strings like
  "1.3.6.$public", "1.3.6$public$" or "1.3.6.$public$1".
- Fixed: Removed a lot of compiler warnings on Windows x64 (with help of
  Sanjay Bhatia). Introduced new type for sockets (SnmpSocket), and
  removed SNMPHANDLE type.
- Changed: Removed global mutex for v3MP and USM.
- Fixed: sockets were not closed if bind failed. (found from John McCaskey)
- Fixed: Engine id discovery did not work when sending SNMPv3 request
  to IPv4 Address over IPv6 socket.
- Fixed: For async SNMPv3 requests that resulted always in a unknown
  engine id or not in time report from the agent the Snmp class continued
  to resend a request to the agent.
- Fixed: USM was not thread safe (found from John McCaskey):
  Changing users from two different threads or changing users
  while messages of these users are processed could cause
  segmentation faults. The following functions of USM now behave
  different than before or require calls to new functions:
  all three get_user() functions, peek_first_user(), peek_next_user(),
  peek_first_luser(), peek_next_luser(), get_user_count().
  If you use any of these functions, read the new documentation in
  usm_v3.h and change your code (like it was done for the QtExample).
- Changed: The functions to set/get the trap listen port of
  CNotifyEventQueue ar no longer static. Use the new functions
  Snmp::notify_set/get_listen_port() instead.
- Removed: Old X11 code, user defined events and timeouts.
- Improved: Counter64 now uses 64 bit integer for math
  operations, instead of long double. 
- Fixed: Zero length UDP packets will no longer trigger
  a transport-level-failed callback.

Changes snmp++v3.2.20a
======================

- Improved: Detect too large received messages.
- Improved: Removed hard coded limit for max number of Vbs
  (PDU_MAX_VBS) in a Pdu object.
- Fixed: Bug in SNMPv3 encryption code which will lead to a
  crash after a random number of encryptions (Stuart Marks).

- Improved: Compilation of address.cpp for Solaris.

Changes snmp++v3.2.19
=====================

- Fixed: Requests with nonzero but wrong security engine id
  now result in a unknown engine id report.
- Added: New functions USM::add_usm_user() and
  new functions to remove engine ids and hosts from
  the v3MP and USM tables.
- Changed: command line arguments of consoleExamples.

Changes snmp++v3.2.18
=====================

- Added: Privacy protocol 3DES. The Auth/Priv interface was
  modifed. (based on patch from Pierre Pacchioni)
- Fixed: Possible memory leak in mp_v3.cpp v3MP::snmp_parse(..).
- Fixed: Uninitialized variable in asn1.cpp asn_parse_length(..).
- Fixed: Uninitialized variables in snmpmsg.cpp 
  SnmpMessage::unload when v3MP::I->snmp_parse() fails.
  (Reported by Rob Crawford)
- Changed: ID of privacy protocol AES128 now is 4
  as required by the RFC.
- Fixed: Vb::get_value(ptr, len, maxlen) may write
  maxlen+1 bytes into ptr buffer (Daniel Suman).
  This function now is  Vb::get_value(ptr, len, maxlen,
  add_null_byte) where the default for add_null_byte
  is false.
- Improved: Workaround for Cisco SNMP agents that set
  request ids to 0x7fffffff in report messages.
- Fixed: Make auth_priv.h/cpp compile if both OpenSSL and
  LibTomCrypt are defined.
- Added: Basic support for VxWorks with PPC603 (Thanks to
  Lee Noll).

Changes snmp++v3.2.17
=====================

- Changed: Updated auth_priv.cpp for LibTomCrypt 1.02
- Changed: Moved logging classes from agent++ into
  snmp++. (Fedja Jeleskovic)
  Function debug_set_logfile() has been removed, use
  DefaultLog::init(new AgentLogImpl("filename")) and
  DefaultLog::log()->set_filter() instead.
  All logging within snmp++ will be moved to the LOG_XXX
  macros and the debugprintf() function will be removed.
- Changed: Renamed "#ifdef alpha" to "#ifdef __osf__". When
  compiling for DigitalUnix/Tru64 make sure, that __osf__
  is defined.

Changes snmp++v3.2.16
=====================

- Improved: notify_register() now returns correct error codes.
- Added: Snmp::start_poll_thread() that starts a new thread
  that polls for async responses and informs/traps. The thread
  will be stopped automatically in the destructor. It also can
  be stopped using Snmp::stop_poll_thread(). (Fedja Jeleskovic)
- Added: New transport layer error code
  SNMP_CLASS_TL_ACCESS_DENIED for (errno == EACCES)
- Improved: new define SNMP_PP_MUTABLE that can be
  defined to mutable for compilers that support
  mutable member variables.

  zero (Mr. AWD)

- Fixed: Set sin_len of struct sockaddr_in before calling
  bind(). Define CYGPKG_NET_OPENBSD_STACK to enable it.
  (Harald Kuethe)
- Changed: Pdu class checks Vb validity after all
  assignments. It is no longer possible to add
  a Vb that is not valid.
  Some set/get member functions now return bool
  instead of void.

Changes snmp++v3.2.14
=====================

- Improved: Return value of Pdu functions 
  get/set_notify_id and get/set_notify_enterprise. 
  (Marek Malowidzki)
- Fixed: Check return value of new in
  SnmpCollection::operator+=() (Marek Malowidzki)

  and _USER_DEFINED_TMEOUTS (enabled by default)
  to switch off the user defined event/timeout queues.
- Improved: Added const to various functions and
  function arguments (Marek Malowidzki)

- Fixed: Added missing DLLOPTs in msec.h (Christian Cheney).

- Improved: The v3MP uses the Snmp object that received
  the message for sending out report messages (needed
  for systems with multiple IP addresses).
  The constructor of the v3MP class was changed, as
  the pointer to the Snmp object is no longer needed
  at construction time.

- Changed: Snmp::notify_register() no longer binds
  to all interfaces, but to the address specified
  in the constructor of the Snmp object.

Changes snmp++v3.2.9d
=====================

- Improved: Removed usage of some multi-threading 
  critical C routines (for example strtok). Although
  on many systems, these routines are multi-threading
  safe, this may not be true for some systems. 

- Fixed: High CPU usage in SNMPProcessEvents() on
  Win32 platform.

- Fixed: SNMPv1 trap sysUpTime TimeTicks where not
  decoded correctly as unsigned integer value, resulting
  in a parse error when sysUpTime > 2^31-1.

- Fixed: USMUserNameTable::add_entry() did not update
  the privacy password length.

- Improved: Examples now use the 
  Snmp::socket_startup() on Win32 platforms.

- Added: Two static methods Snmp::socket_startup() and
  Snmp::socket_cleanup() that initialize/cleanup
  Winsock library on WIN32 and do nothing for
  other platforms. The startup method must be
  called before creating Snmp or Address objects.

- Changed: Type of some vars in UsmUserNameTableEntry
  from uchar* to OctetStr. Check if your code uses 
  this struct.
- Changed: engineBoots and engineTime are set to 0 for
  SNMPv3 noAuthNoPriv messages.

Changes snmp++v3.2.8
====================

- Added: Support for OpenSSL.
- Fixed: Compile problem in uxsnmp.cpp.

  (Kent Gibson)
- Changed: EventListHolder::SNMPProcessEvents() 
  param is now in milliseconds (was seconds).

- Fixed: Memory leak if an async SNMPv3 message timed
  out (Henning Eggers).

  usage with a GUI (Trolltechs Qt 3.1).
- Added: Methods to store, load, and query USM users.
- Improved: Some minor clean-ups.

Changes snmp++v3.2.6b
=====================

- Fixed: GenAddress passed IPv4 addresses as IPv6 
  addresses.
- Changed: By default IDEA is not compiled into 
  SNMP++ by default because patent licensing is
  required for commercial use. Please #define 
  _USE_IDEA if you want to compile IDEA into SNMP++.
  For more details please read also README.v3.

- Fixed: Do not add -Dsun to compile command. If
  you have problems with the SnmpCollection template
  look at the instructions in collect.h. 
- Fixed: Destroy Mutex in ~EventListHolder(). 
- Improved: Lots of cleanups for the address classes.
  This leads to the following incompatibilities to 
  former versions:
  + Enums addr_type and version_type are now inside
    class Address
  + MacAddress, IpxAddress and IpxSockAddress are no
    longer included by default, but can be enabled
    in config_snmp_pp.h 

Changes snmp++v3.2.5d
=====================

- Improved: Made AuthMD5::password_to_key more
  robust against empty passwords.
- Changed: The Win32 DLL export macros now use
  SNMP_PP_DLL instead _USRDLL.

  char* or unsigned char* as argument
- Added: operator+() for Oids (Alexander Gutkin)
- Improved: Cleanups in queues 

Changes snmp++v3.2.4a
=====================

- Improved: Synchronous and asynchronous SNMP
  request processing is now separated. Thus,
  the global event lists have been removed. 
  Each Snmp class now holds its own event 
  lists.
  To eliminate the use of global event lists
  a new class EventListHolder was defined. Two
  new files eventListHolder.h and 
  eventListHolder.cpp contain now declaration
  and definition of that class respectively.
  That new class is a container of former
  eventList global data structure and former
  global user defined events, user-defined 
  timeouts, notifications and all outstanding
  messages. (LiorK)
- Improved: collect.h (Bill McKinnon)
- Improved: FreeBSD 5.0 support.

- Added: Makefile.gcc_solaris for compilation
  with GNU C++ compiler on Solaris.

- Fixed: Compilation problems without _SNMPv3
  defined.
- Fixed: PDU length computation for encrypted
  SNMPv3 PDUs.

         wrong counter.

- Update: The changes of the official SNMP++ 2.84 from HP were
          merged into snmp++v3.

- Changed: The snmpEngineBoots counters for different
           snmpEntities can now be saved in one file. For this
           the function mpInit had to be changed. See
           include/v3.h for more information about the new functions
           getBootCounter, saveBootCounter and decodeEngineId.
           Example:

           char *filename = "snmpv3_boot_counter";
           unsigned int snmpEngineBoots = 0;
           OctetStr engineId("exampleId");

           // you may use your own methods to load/store this counter
           status = getBootCounter(filename, engineId, snmpEngineBoots);
           if ((status != SNMPv3_OK) && (status < SNMPv3_FILEOPEN_ERROR))
             cerr << "Error getBootCounter: " << status << endl;

           snmpEngineBoots++;
           status = saveBootCounter(filename, engineId, snmpEngineBoots);
           if (status != SNMPv3_OK)
             cerr << "Error saveBootCounter: " << status << endl;

           mpInit(&snmp, engineId, snmpEngineBoots);

- Fixed: Reports for encryption error were sent with a
         securityLevel authPriv, now authNoPriv is used.
         Reports for unknown security name were sent with
         user 'initial', now the user name of the request
         is used.

- Fixed: Snmp::trap now sets the timestamp of traps for WIN32
         and for non WIN32 to the same value if the user didn't
         set it with pdu::set_notify_timestamp().
         Note: Snmp::trap does not set the timestamp to the
         uptime of the system or the application. The timestamp
	 is computed from the time elapsed since 1970/1/1.

- Fixed: msec::refresh() now sets the correct time for WIN32 

- Changed: mpAddToEngineIDTable now replaces host and port
           when adding an engineID that is already in the table

- Fixed: OctetStr::from_hex_string()


Changes snmp++v3.0c
===================

- Fixed: Class Address had no default constructor.

- Added: mpIncSnmpUnknownSecurityModels(),
	 mpIncSnmpInvalidMsgs(),
	 mpIncSnmpUnknownPDUHandlers().

Changes snmp++v3.0b
===================

- Fixed: SNMPv3 reports for inform requests are now sent
         through the socket that is used to listen for
         traps/informs. 

- Added the static method
  CNotifyEventQueue::set_listen_port(int port);
  to set the trap listen port. Call this method before calling
  Snmp::notify_register(...). The default port is 162.


Changes snmp++v3.0a
===================

- Internal changes in SNMPv3 implementation

- Changes in structures for SNMPv3 async requests

- Some documentation added.

- Fixed: usmDeleteUserName mixed userName and securityName.
         Changed parameter of usmDeleteUserName to userName
         and added new function usmDeleteSecurityName.

- Fixed: the SNMP version of targets created through 
         CTarget(const CTarget) was set to version1
         (same for operator=(constCTarget))

- Changed call of "delete X" to "delete [] X" where necessary

- Moved some structure definitions from header files to cpp-files.
  Changed some internal structures from unsigned char to OctetStr.


Changes snmp++v3.0:
===================

- uxsnmp.cpp: line 656-660

  Added WSACleanup() routine for NT.

- smi.h: line 141

  Changed ASN.1 tag value of UInt32 to 2 (same as Gauge32)

  #define sNMP_SYNTAX_UINT32    sNMP_SYNTAX_GAUGE32

  removed duplicate case labels in asn1.cpp, snmpmsg.cpp and gauge.cpp

- snmpmsg.cpp: line 355

  Changed snmpTrapOID to

   tempvb.set_oid("1.3.6.1.6.3.1.1.4.1.0");

- Added const to Pdu::get methods where applicable. 

- Added static function OctetStr::from_hex_string().

- Added DLLOPT to all public functions / classes.

- Using memset and memcpy instead the deprecated counterparts 
  bzero and bcopy.

- Using WinSockets on WIN32 platforms.

- When converting an oid string to an oid (Oid::StrToOid) now an
  arbitrary part of the oid can be given as a string value enclosed in
  $ characters. For example the oid string

  "1.3.6.1.6.1.12.1.3.$public0$" 

  will result to the oid

  1.3.6.1.6.1.12.1.3.112.117.98.108.105.99.95.48

- the function mpInit is now called with a pointer to an Snmp object
  and an engineID: int mpInit(Snmp *snmp, const OctetStr& snmpEngineID);

- New target (UTarget for SNMPv3):
  - Methods to get/set security_name and security_model:
    void get_security_name( OctetStr& security_name_oct);
    void set_security_name( const OctetStr& new_security_name);

    void set_security_model(int sec_model);
    int get_security_model();

  - If you know the engine_id of the target (no engine_id discovery):
    void set_engine_id( const OctetStr& new_engine_id);
    void get_engine_id( OctetStr& engine_id_oct);

  --> most methods of CTarget do exist for UTaget: see target.h

  For SNMPv3 there is only one valid security_model (SNMP_SECURITY_MODEL_USM).
  If you set the security_model to SNMP_SECURITY_MODEL_V1 (or V2) you can use
  te UTarget to send SNMPv1 (v2c) requests.

- New methods for Pdu objects:

  void set_security_level( const int level);
  int get_security_level();

  void set_context_name(const OctetStr &name);
  void get_context_name(OctetStr &name);

  void set_context_engine_id(const OctetStr &id);
  void get_context_engine_id(OctetStr &id);

  valid security_levels are: SNMP_SECURITY_LEVEL_NOAUTH_NOPRIV,
  SNMP_SECURITY_LEVEL_AUTH_NOPRIV and SNMP_SECURITY_LEVEL_AUTH_PRIV


- The CTarget can no longer be used as a SNMPv3 target. The methods
  mpBuildCommunity and mpParseCommunity don't exist any longer.


- The consoleExamples now use a CTarget for SNMPv1/v2c requests and
  UTarget for SNMPv3 requests. There are new examples: snmpInform
  (to send inform Requests) and receive_trap.
