6.15-stable review patch. If anyone has any objections, please let me know.

commit c1846893991f3b4ec8a0cc12219ada153f0814d6 upstream.
When the server interface info changes (more common in clustered servers like Azure Files), the per-channel iface gets updated. However, this did not update the corresponding dstaddr. As a result these channels will still connect (or try connecting) to older addresses.
Fixes: b54034a73baf ("cifs: during reconnect, update interface if necessary") Cc: stable@vger.kernel.org Signed-off-by: Shyam Prasad N sprasad@microsoft.com Signed-off-by: Steve French stfrench@microsoft.com Signed-off-by: Greg Kroah-Hartman gregkh@linuxfoundation.org --- fs/smb/client/sess.c | 4 ++++ 1 file changed, 4 insertions(+)
