When read_message returns -1 while a read is pending, an attempt is made to lock h->request_mutex which is already locked by the reader. Change the read thread to only exit on thread cancellation, where read_thr_exists will return 0. Signed-off-by: Daniel De Graaf <dgdegra@xxxxxxxxxxxxx> -- Daniel De Graaf National Security Agency
