Roman Smirnov 64ddb14fd0 cifs: fix integer overflow in match_server() ... [ Upstream commit 2510859475 ] The echo_interval is not limited in any way during mounting, which makes it possible to write a large number to it. This can cause an overflow when multiplying ctx->echo_interval by HZ in match_server(). Add constraints for echo_interval to smb3_fs_context_parse_param(). Found by Linux Verification Center (linuxtesting.org) with Svace.
