Recent testing of the NFS-over-TLS code found a LOR between the mutex lock used for sessions and the sleep lock used for server side krpc socket structures. The code in nfsrv_checksequence() would call SVC_RELEASE() with the mutex held. Normally this is ok, since all that happens is SVC_RELEASE() decrements a reference count. However, if the socket has just been shut down, SVC_RELEASE() drops the reference count to 0 and acquires a sleep lock during destruction of the server side krpc structure. This patch fixes the problem by moving the SVC_RELEASE() call in nfsrv_checksequence() down a few lines to below where the mutex is released. MFC after: 1 week |
