Changes snmp++v3.2.21a======================- 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.- 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.- Changed: renamed OctetStr::set_hex_np_char() to  set_np_char()- Improved: get_printable() will return the same buffer  for each call if the object wasn't changed.- Added: Pdu::get_max_vbs() to get the value of  PDU_MAX_VBS at runtime.- Fixed: Bug in snmperrs.h (Jason Olenhouse)Changes snmp++v3.2.15=====================- Fixed: Bug in asn1.cpp for systems where  sizeof(long) != sizeof(*long) (Hu Shu)- Fixed: timeout calculation in  EventListHolder::SNMPProcessEvents() (Xu Manjiang)- Fixed: OctetStr::clear() now sets the length to  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)- Fixed: Setting a byte with Address::operator[] will  set validity of the object to true.- Improved: Behaviour of OctetStr::get_printable() for  non printable strings can now be configured.Changes snmp++v3.2.13a======================- Fixed: Version info was not updated.- Fixed: Compilation problems with _NO_SNMPv3- Changed: The user "initial" is no longer automatically  added to the USM.- Fixed: Oid class freed memory twice after  failed call to operator+=().- Added: Support for AIX 5 (by courtesy of  Anders Malmborg)Changes snmp++v3.2.12a======================- Fixed: wrong encryption/decryption for  DES and IDEA.- Fixed: consoleExamples can use IPv6.- Fixed: Do not accept illegal lengths for  authentication parameters.- Removed: Obsolete XExample.- Fixed: Compilation problem in address.cpp  if __sun is defined (Kostas Lykiardopoulos)- Improved: Modified constructor of Snmp class  to allow binding to IPv6 socket.- Added: AES can now be used with OpenSSL.- Improved: Compilation under Tru64.- Fixed: Return code of delete_entry and   delete_entries in class USMUserTable returned  SNMPv3_MP_OK instead SNMPv3_USM_OK.Changes snmp++v3.2.11=====================- Improved: Declared some methods as const  (Marek Malowidzki).- Improved: Use shortest possible encoding for  serializing SNMP messages to improve compatibility  with buggy/broken SNMP-Tools (Henning Eggers).- Fixed: Compilation problems on SUN  (Fabrice Bacchella)- Improved: declared some methods as const- Improved: Moved the headers to include/snmp_pp/  to avoid name colissions.- Improved: QtExample can receive traps/informs.- Fixed: Compilation problems with BC++ 5.0  (Vinoth, Christian Cheney)- Improved: Added namespace Snmp_pp (Sorin C.)Changes snmp++v3.2.10a======================- Changed: Added two defines _USER_DEFINED_EVENTS  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.- Improved: Log levels.- 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. Changes snmp++v3.2.7c=====================- Fixed: Synchronization problem with mpV3::Cache.  (Henning Eggers)- Fixed: Memory leak in OctetStr::from_hex_string.  (Kent Gibson)- Changed: EventListHolder::SNMPProcessEvents()   param is now in milliseconds (was seconds).- Fixed: Memory leak if an async SNMPv3 message timed  out (Henning Eggers).- Added: Method Snmp::broadcast_discovery() to do  SNMP broadcast discovery. - Improved: Console examples now accept 0 retries,  removed warnings with gcc 3.2, and v3MP is now  always created.- Added: Qt 3.1 example that demonstrates SNMP++v3  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.- Changed: Moved VC++ project files in a   separate package. - Improved: Minor issues with IPv6 support.- Improved: Socket handling.- Fixed: uxsnmp.cpp: Detecting error from socket()  return values.- Fixed: Moved SNMPAddInput() SNMPRemoveInput()  SNMPAddTimeout and SNMPREmoveTimeout to the  class EventListHolder- Fixed: Unique Id generation in CUDEventQueue and  CUTEventQueue.- Fixed: Bugs in Vb::get_value() methods that take a  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.	Changes snmp++v3.2.3b=====================- Fixed: Counter64::get_printable() could print  negative values (Yakov Y.)- Note: New Makefiles assume that you have  defined _USE_LIBTOMCRYPT when a "crypt"  directory is present in the same folder as  the "snmp++" and "agent++" directories. - Fixed: Compilation problems without _SNMPv3  defined.- Fixed: PDU length computation for encrypted  SNMPv3 PDUs.- Improved: New v3MP class.- Fixed: Estimated length calculation for   encoded PDU.Changes snmp++v3.2.2d=====================- Fixed: Possible timeouts under heavy load  in a multi-threaded environment.   [Pavel Spakovsky]- Fixed: DLL support for VC++ did not allow  static linking.- Added: Computation of BER encoded length of  a Pdu. - Added: VC++.NET project files and fixed DLL  support.- Fixed: Errors in Counter64::c64_to_ld() and  Counter64::ld_to_c64() [Mikhail Evstiounin]- Improved: Prepared for AES usage replacing  libDES. - Fixed: Compilation problems with G++3.2  (needs updated libDES download).Changes snmp++v3.2.1d=====================- Fixed: Memory leak (40 bytes) when adding an  user to usm.- Improved: Some cleanups (#include, const).- Fixed: Due to possible race condition in  MyMakeReqId() (uxsnmp.cpp) two requests could  get the same request id. - Fixed: const casting caused problems with  AIX compiler.Changes snmp++v3.2.1====================- Improved: Use zero length user name for  SNMPv3 discovery.- Lots of cleanups.Changes snmp++v3.2a===================- Fixed: Compilation problem with address.cpp on  Solaris. Changes snmp++v3.2==================- Added: IPv6 support.- Improved: moved the USM functions into the class  USM. To add or delete users, you will now have to  do the following (see usm_v3.h for more details):     Usm *usm = mpGetUsm();     usm->add_usm_user(...);     usm->delete_usm_user(...);- Fixed: Possible SegFault in notify queue  (Lior Klibansky)- Fixed: Timeout problem in event list (Don Dietz)- Fixed: Don't use isdigit() for BCC (Eric Zerbib)- Added: clear() method to SnmpCollection- Fixed: added clone() method to Pdu class, so  SnmpCollection<Pdu> will work again.- Added: Make notify socket decriptor available in  Snmp class (Don Dietz)Changes snmp++v3.1.6c=====================- Fixed: mp_v3.cpp: Unsigned integer values were  not BER decoded correctly for SNMPv3 messages.- Fixed: Some errors when compiling with -ansi- Improved: Class AuthPriv does no longer depend  on USM. Changes snmp++v3.1.6b=====================- Added: BCC32 support.- Added: DLLOPT decoration for debugprintf.Changes snmp++v3.1.6a=====================
