----------------------------------
Summary: fuzz-connection-driver.c exits with 1 when the engine
stops accepting additional input
Key: PROTON-2136
URL: https://issues.apache.org/jira/browse/PROTON-2136
Project: Qpid Proton
Issue Type: Test
Components: proton-c
Affects Versions: proton-c-0.29.0
Reporter: Jiri Daněk
Assignee: Jiri Daněk

size_t fcd_read(pn_connection_driver_t *driver, uint8_t **data, size_t *size) {
pn_rwbytes_t buf = pn_connection_driver_read_buffer(driver);
size_t s = (*size < buf.size) ? *size : buf.size;
if (buf.start == NULL) {
exit(1);
}

The engine offers a null buffer for further input. AFAIK that is legit, because
it is just that the "socket" was closed for further input, after reading the
invalid header.
The fuzz target should just return peacefully at this point and not crash.
