( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/556291?usp=email ) Change subject: PSEUDO_FSAL: Fix access to non-initialized structs in handle ...................................................................... PSEUDO_FSAL: Fix access to non-initialized structs in handle In verify_handle_is_valid we accessed the state_hdl, but it wasn't initialized. It is only initialized in MDCache, and so we cannot access if from within the FSAL. This could cause a segmentation fault. I removed verify_handle_is_valid, but it was intended to prevent a race where a lookup returns a file handle before the export update process is done updating its junction_export. In order to avoid this race I changed lookup and readdir to always return ERR_FSAL_DELAY when export update is in progress. This caused another issue, where the export update process itself calls lookup when it creates the node. In order to allow it to get the correct response during the export update I use op_ctx->fsal_private to signal to the FSAL that it should return the current response.
