ext_proc fuzzer is hitting below crash. This is due to some of the mock functions of decoder_callbacks is missing, which causing the state.addBufferedData() is no-op. This issue is a fuzzer only issue. [2023-05-25 17:25:25.880][4130221][debug][ext_proc] [source/extensions/filters/http/ext_proc/processor_state.cc:30] Traffic direction INBOUND: 200 ms timer enabled

Is there a reason the assignment is being done as part of the Return statement?
I suggest returning the address of buffer_ directly.

Not sure I fully understand this, but I thought that the default behavior of a (Nice)Mock is to return the default value. Do these override a different ON_CALL somewhere?

Yeah,no need. removed.

Fix an ext_proc fuzzer issue.
The crash issue is due to some of the decoder_callbacks mock function are missing. Adding them.
