When a\nSYN is rejected with TIPC_ERR_OVERLOAD and the retry path in\ntipc_sk_filter_connect() executes:\n\n delay %= (tsk->conn_timeout / 4);\n\nIf conn_timeout is in the range [0, 3], the integer division yields 0,\nand the modulo operation triggers a divide-by-zero exception, causing a\nkernel oops/panic.\n\nFix this by clamping conn_timeout to a minimum of 4 at the point of use\nin tipc_sk_filter_connect().\n\nOops: divide error: 0000 [#1] SMP KASAN NOPTI\nCPU: 0 UID: 0 PID: 119 Comm: poc-F144 Not tainted 7.0.0-rc2+\nRIP: 0010:tipc_sk_filter_rcv (net/tipc/socket.c:2236 net/tipc/socket.c:2362)\nCall Trace:\n tipc_sk_backlog_rcv (include/linux/instrumented.h:82 include/linux/atomic/atomic-instrumented.h:32 include/net/sock.h:2357 net/tipc/socket.c:2406)\n __release_sock (include/net/sock.h:1185 net/core/sock.c:3213)\n release_sock (net/core/sock.c:3797)\n tipc_connect (net/tipc/socket.c:2570)\n __sys_connect (include/linux/file.h:62 include/linux/file.h:83 net/socket.c:2098)"
