Martijn van Beurden 76e8f22b4c Clean up and add to fuzzer_encoder (v1) 
Now fuzzer_encoder_v2 has been running for quite some time and no
big (encoder) projects are coming, fuzzer_encoder is changed. This
will invalidate the current corpus which will take time to rebuild,
but I think this is a good moment to do so.

Martijn van Beurden 96b5e6d35a Check vorbis comment entry before copying 
Whereas in C vorbis comment fields are in an array, C++ actually
validates the comment before returning it. This means it needs a
little more checking.

Martijn van Beurden 5bc582b2c7 Fix some OOM metadata bugs, disable OOM checking in metadata fuzzing 
For now OOM emulation in fuzzer_metadata is disabled, as I really
want to get as much merged as soon as possible. Need to get back
to this at some point

Martijn van Beurden 1f21ae2702 Add write callback abort check to seeking fuzzer 
If the write callback calls for an abort, this must be honored.
This commit adds a check to ascertain the write callback isn't
called again

Prepare oom checking in fuzzing 
By merging oom checking in fuzzing in steps, it is possible to
implement it without having oss-fuzz build failures

 2022-05-11 10:34:49 +02:00
Martijn van Beurden 87a5f3e952 Add abort on encoding error that should not happen 
This commit lets the following errors trigger an abort:
- FLAC__STREAM_ENCODER_OGG_ERROR
- FLAC__STREAM_ENCODER_VERIFY_DECODER_ERROR
- FLAC__STREAM_ENCODER_VERIFY_MISMATCH_IN_AUDIO_DATA
- FLAC__STREAM_ENCODER_IO_ERROR
- FLAC__STREAM_ENCODER_FRAMING_ERROR
- FLAC__STREAM_ENCODER_MEMORY_ALLOCATION_ERROR

FLAC__STREAM_ENCODER_CLIENT_ERROR does not trigger an abort because
it is used to signal invalid input. FLAC__STREAM_ENCODER_UNINITIALIZED
does not trigger an abort because init fails when invalid parameters
are given

Martijn van Beurden b64ea1171b Fix fuzzer_encoder_v2 timeouts 
This fixes the 'false positive' oss-fuzz bug filed under
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=47264

The fuzzer was timing out because of an enormous input (932kB)
combined with very slow settings. The commit disables certain
slow settings on inputs larger than 2^18 byte.

Martijn van Beurden b52734242e Add fuzzer_encoder_v2 
Add additional fuzzer for the encoder, aiming to reach more coverage
than the current encoder fuzzer. This is done by incorporating
metadata handling and fixing a problem with different settings in
the current fuzzer
