Programs assuming that PVNAME_STRINGSZ is always enough memory to store a record name unchecked may get buffer overruns.


Inside the IOC, most things should work [TM].

Channel Access clients need to remember they have to use "long string" type (arrays of byte) when such names are part of the data. (E.g., when setting link fields.)

Other external applications to check include:
Operator Interface
Alarm handling
Archive engines
Archive retrieval
Development environment
Configuration management / databases
Directory services (ChannelFinder etc.)

Cheers,
