From 6e1c1c08cdf3d7d7b8c571c0f032a283af6ca024 Mon Sep 17 00:00:00 2001 From: Shyam Prasad N Date: Mon, 6 Jun 2022 09:17:56 +0000 Subject: cifs: periodically query network interfaces from server Currently, we only query the server for network interfaces information at the time of mount, and never afterwards. This can be a problem, especially for services like Azure, where the IP address of the channel endpoints can change over time. With this change, we schedule a 600s polling of this info from the server for each tree connect. An alternative for periodic polling was to do this only at the time of reconnect. But this could delay the reconnect time slightly. Also, there are some challenges w.r.t how we have cifs_reconnect implemented today.
