---------------------------------------
Summary: TLS OpenSSL library: incomplete decryption/encryption of
staged buffers
Key: PROTON-2586
URL: https://issues.apache.org/jira/browse/PROTON-2586
Project: Qpid Proton
Issue Type: Bug
Components: proton-c
Affects Versions: proton-c-0.37.0
Reporter: Clifford Jansen
Assignee: Clifford Jansen
OpenSSL processes TLS records one at time. It does its conversion work in
buffers just larger than a maximum sized TLS record (16K). When processing
large sized input and output buffers in a single pn_tls_process() call, the
Proton TLS library has to loop inserting unprocessed data into the small
OpenSSL buffer and extract the encrypted/decrypted data into the output buffer
and free space for the next iteration. The code currently can exit the loop
prematurely.
