From 4963d74f8a6cc0eafd71d9ffc13e3a11ff1dd160 Mon Sep 17 00:00:00 2001 From: Atte Heikkilä Date: Tue, 9 Aug 2022 01:02:14 +0300 Subject: ksmbd: request update to stale share config MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ksmbd_share_config_get() retrieves the cached share config as long as there is at least one connection to the share. This is an issue when the user space utilities are used to update share configs. In that case there is a need to inform ksmbd that it should not use the cached share config for a new connection to the share. With these changes the tree connection flag KSMBD_TREE_CONN_FLAG_UPDATE indicates this. When this flag is set, ksmbd removes the share config from the shares hash table meaning that ksmbd_share_config_get() ends up requesting a share config from user space.
