| Description |
|
Test failure shows that read-on-open happens in case when it shouldn't. The reason is bigger reply buffer than test expects. |

With new OPEN intent buffer for SECCTX, total allocated reply size become 256K, while test expect it be smaller, this is to be fixed in test script. Meanwhile the log analysis shows that server may also return bigger buffer back causing buffer re-allocation and resend from client. The problem is req_capsule_server_grow() being called after req_capsule_shrink(), it uses non-updated buffer lengths and pack bigger reply than needed. |
