Release Notes

lextudio/pysnmp (pysnmp)

v4.4.12

Compare Source

• Fixed broken SNMPv3 msgFlag initialization on authoritative SNMP
  engine ID discovery. This bug causes secure communication with peer
  SNMP engines to stall at SNMP engine ID discovery procedure.

v4.4.11

Compare Source

• Added SNMPv3 USM master and localized keys support to LCD configuration
• Improved initial and runtime USM debugging
• Fixed a bug in USM configuration which did not allow the same user names
  to be added under different security names

v4.4.10

Compare Source

• Reworked VACM access control function. Most important changes include:

  • Added subtree match negation support (vacmViewTreeFamilyType)
  • Added subtree family mask support (vacmViewTreeFamilyMask)
  • Added prefix content name matching support (vacmAccessContextMatch)
  • Added key VACM tables caching for better isAccessAllowed lookup
    performance

  One potential incompatibility may be caused by the addContext() call
  which now needs to be made explicitly during low-level VACM configuration
  rather than be a side effect of addVacmAccess() call.

• Rebased MIB importing code onto importlib because imp is long
  deprecated

• Received MIB objects resolution made more forgiving to errors, added
  optional ignoreErrors parameter to ObjectType.resolveWithMib() to
  control that behaviour.

• Fixed asyncore main loop to respect non-default timer resolution

• Fixed .setTimerResolution() behaviour of abstract main loop dispatcher
  to update call intervals of the existing periodic dispatcher jobs

• Fixed var-bindings initialization to prevent pyasn1 encoder failures
  with newer pyasn1 versions where SequenceOf type looses its default
  initializer.

• Fixed crash on uninitialized component serialization left out in
  SNMP v1 TRAP PDU to SNMPv2/3 TRAP PDU proxy translation routine.

v4.4.9

Compare Source

• Made MIB loader ignoring file and directory access errors
• Added missing SNMP PDU error classes and their handling in Command Responder
• Fixed crash on MIB load failure in case of directory access error
• Fixed socket transparency option (IPV6_TRANSPARENT) to make IPv6
  transparent operation functional
