Release Date

March 3, 2020

• Open-source Release

V2.01.02

Release Date

January 22nd, 2020

Bug Fixes

• Fixed null pointer dereference in DNScCache_HostObjGet() when performing forward lookups.

V2.01.01

Release Date

September 20th, 2019

Requirements

• µC/TCP-IP V3.03.00 or more recent.
• µC/CPU V1.30.00 or more recent.
• µC/LIB V1.38.00 or more recent.
• µC/Common V1.00.00 or more recent [optional].
• µC/Shell V1.03.01 or more recent [optional].

New features & improvements

• (450) µC/DNSc can now process the canonical name returned in answers to forward DNS requests by setting DNSc_FLAG_CANON in the 'flags' argument.
• (635) Implemented IPv6 reverse DNS requests.
• (714) Prevented possible compiler warning when both DNSc_SIGNAL_TASK_MODULE_EN and DNSc_TASK_MODULE_EN are configured by removing the exit_cache_remove from DNScTask_HostResolve().

API Changes

• DNSc_GetHost()
  • The 'p_rev_host_name' and 'rev_hostname_len' arguments were renamed to 'p_res_host_name' and 'res_hostname_len', respectively
    in order to reflect that the string receives the resolved canonical OR reverse name for the host.

Bug Fixes

• (699) Fixed bugs with the argument checking in DNSc_GetHost().
  • The 'p_addr_nbr' parameter was not being checked for correct values.
  •  DEF_BIT_SET() was being used instead of DEF_BIT_IS_SET() when checking if DNSc_FLAG_NO_BLOCK was set in 'flags'.
  •  The validity of the DNSc_FLAG_NO_BLOCK flag if present in 'flags' parameter was done incorrectly if the DNS task was configured to block.
• (700) Fixed typographical error in code that checked whether the argument checking feature was enabled in the DNS configuration.
• (701) Reverse lookups wouldn't update the 'p_rev_host_name' parameter if the host was already in the cache.
• (739) DNScCache_ItemRemove() failed to advance linked list pointers causing an infinite loop.
• (743) DNScCache_Resolve() does NOT handle DNSc_ERR_TX_FAULT as it transitions from DNSc_STATE_TX_REQ_IPv(4/6).

Known Issues

• None.
