Steve Karg a70ce07507 Secure BACnet decoders and service requests (#1244)
* Secured BACnetAssignedAccessRights decoder.

* Secured BACnetPropertyState decoder.

* Secured BACnetCredentialAuthenticationFactor decoder.

* Secured BACnetEventState change-of-state [1] SEQUENCE decoder.

* Secured I-Have-Request service decoder.

* Secured Add/Remove ListElement service request decoder.

* Secured ConfirmedPrivateTransfer-Request and UnconfirmedPrivateTransfer-Request decoders.

* Secured ReadPropertyMultiple-Request and -Ack decoders.

* Secured TimeSynchronization-Request decoder.

* Secured WritePropertyMultiple service decoders

* Secured Trend Log object TL_fetch_property() function.

* Secured ReadProperty-Ack decider,

* Refactor BACnet time sync recipient handling by moving timesync linked list structure into bacdest where the recipient encoder and decoder already existed.

* Secured decoding of BACnetPropertyState.

* Secured decoding in the LifeSafetyOperation-Request service.

* Secured BACnetAuthenticationFactor decoding in the Credential Data Input object.

* Fixed WriteProperty decoder to avoid read buffer overrun.  Improved WriteProperty error reporting by adding specific reject codes during decoding similar to WritePropertyMultiple. Deduplicated the WriteProperty handling of abort, reject and error codes.

* Added BACNET_STACK_DEPRECATED_DISABLE guards around all of the deprecated decoding functions to ensure they are not used except intentionally for legacy code bases.

* Changed version to 1.5.0.rc5 for security fix tracking in branch.

Steve Karg cf4f62f7e0 Added Who-Is-Router process for Notification Class recipient unknown router addresses. (#1243)
* Added Who-Is-Router-To-Network process in basic Notification Class when recipient address is missing the router MAC address.

* Added buffer_length parameter to octet string buffer decode functions

* Fixed BACnet address handling for I-Am-Router address updating the recipient list address for the next hop router.

* Changed VMAC encoding and decoding to use octet string buffer API to reduce stack RAM.

Steve Karg ca9836b099 Added BACnetRecipient and BACnetAddressBinding codecs for EPICS application (#1163)
* Added BACnetRecipient and BACnetAddressBinding encoding, decoding, ASCII conversion, comparison, and copy functions.

*  Added library specific string manipulation utilities including strcmp, strncmp, stptok, and snprintf with offset functions.

* Added test/README about verification and validation testing.

Steve Karg 55107e96b7 Bugfix/issues 1082 AddListElement and RemoveListElement and Notification Class object (#1083)
* Fixed AddListElement and RemoveListElement which were checking the wrong return value from Device object.

* Fixed decoding of ListElement Tag 0: Object ID instance.

* Fixed Notification_Class_Add_List_Element() and Notification_Class_Remove_List_Element() element counter index, and empty slot detection.

* Added bacnet_recipient_device_set() and bacnet_recipient_address_set() API

* Added unit test coverage for Notification Class object.

Steve Karg 6b6be4a434 Added check for zero length buffer size in primitive decoders that returns zero to enable simpler complex value optional element decoding. (#876) 2024-12-18 15:29:27 -06:00
Kari Argillander a2f1d6959d Make most of functions const correct (#714)
* Make most of the functions const correct

Used clang-tidy and sonarlint to help find places where const could
pretty easily applied. Also lot of hand work.

This commit does not yet touch handlers and typedefs of those.

* Fix Arduino uno handler_who_is() has extra parenthesis

For some reason there is extra parenthesis. Remove it this is more
likely buildable.

* Bugfix/bacapp: Fix uninitilized array_index

We have changed bacapp_snprintf_value() to be const correct. After that
we got

```
/home/runner/work/bacnet-stack/bacnet-stack/src/bacnet/bacapp.c:3183:27: warning: 4th function call argument is an uninitialized value [core.CallAndMessage]
                ret_val = bacapp_snprintf_weeklyschedule(
                          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 warning generated.
```

So analyzer could now spot that we do not actually initilize array_index
at all. Fix this by setting array_index to zero. Note that I actually do
not know if zeroing is right thing to do here. I choose zero as if this
has worked before it is most likely that it will work with zero value.

* cmake: Add and ignore Wwrite-strings compiler option

Wwrite-strings helps find places where const correctness is broken.

Example it will warn about these

```C

void func1(char* str);

func("test") /* "test" is const so we should not pass it to func1().

char* func2()
{
  return "test"; /* func2() should return const char*.
}
```

We still need to ignore it as not all are fixed but let's add it already
so we remember that it should be opened at some point.
