Eugene Petrenko updated SSHD-629:
---------------------------------
Affects Version/s: 1.0.0
> java.lang.IllegalStateException: Bad item length: 89430
> -------------------------------------------------------
>
> Key: SSHD-629
> URL: https://issues.apache.org/jira/browse/SSHD-629
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 1.0.0
> Reporter: Eugene Petrenko
>
> I updated default properties of the server to set default packet length to be
> 4mb. Via code like that
> ```
> mySSHD.getProperties().put(FactoryManager.MAX_PACKET_SIZE, 4 * MB);
> ```
> Next we connected it to jsch ssh client, that was able to increase send
> buffer size beyond 64kb limit. This makes an assert in AbstractChannel.java
> to fail.
> From the code I see the buffer size is compared to ByteArrayBuffer.MAX_LEN
> which is 64k.
> ```
> int len = buffer.getInt();
> if (len < 0 || len > ByteArrayBuffer.MAX_LEN) {
> throw new IllegalStateException("Bad item length: " + len);
> }
> ```
> Actual exception I received in my code was
> ```java.lang.IllegalStateException: Bad item length: 89430

> Let's either deny setting packet size too bit or allow it to be used in the
> code
