Hello all,
This fix addresses a problem first found by Netty/Jetty when decrypting
payloads in excess of ~4096 bytes using one of the ChaCha20-Poly1305
cipher suites. The root cause of the issue is not in the TLS code, it
is actually an issue with how ChaCha20-Poly1305 was implementing
CipherSpi.engineGetOutputSize().
The bug was also partially worked around due to changes in CipherSpi
from 8181386, but this properly addresses the output buffer sizing.
Thanks to Adrian Todt and Bradley Wagner for the Catnip and Jetty
support while trying to replicate the issue originally.
