QoSify is simple daemon for setting up and managing CAKE along with a custom eBPF based classifier that sets DSCP fields of packets. It supports the following features: - simple TCP/UDP port based mapping - IP address based mapping - priority boosting based on average packet size - bulk flow detection based on number of packets per second - dynamically add IP entries with timeout - dns regex entries and ubus api for providing dns lookup results It can be configured via ubus call qosify config. This call supports the following parameters: - "reset": BOOL Reset the config to defaults instead of only updating supplied values - "files": ARRAY of STRING List of files with port/IP/host mappings - "timeout": INT32 Default timeout for dynamically added entries - "dscp_default_udp": STRING Default DSCP value for UDP packets - "dscp_default_tcp": STRING Default DSCP value for TCP packets - "dscp_prio": STRING DSCP value for priority-marked packets - "dscp_bulk": STRING DSCP value for bulk-marked packets - "dscp_icmp": STRING DSCP value for ICMP packets - "bulk_trigger_pps": INT32 Number of packets per second to trigger bulk flow detection - "bulk_trigger_timeout": INT32 Time below bulk_trigger_pps threshold until a bulk flow mark is removed - "prio_max_avg_pkt_len": INT32 Maximum average packet length for marking a flow as priority - "interfaces": TABLE of TABLE netifd interfaces to enable QoS on - "devices": TABLE of TABLE netdevs to enable QoS on interface/device properties: - "bandwidth_up": STRING Uplink bandwidth (same format as tc) - "bandwidth_down": STRING Downlink bandwidth (same format as tc) - "ingress": BOOL Enable ingress shaping - "egress": BOOL Enable egress shaping - "mode": STRING CAKE diffserv mode - "nat": BOOL Enable CAKE NAT host detection via conntrack - "host_isolate": BOOL Enable CAKE host isolation - "autorate_ingress": BOOL Enable CAKE automatic rate estimation for ingress - "ingress_options": STRING CAKE ingress options - "egress_options": STRING CAKE egress options - "options": STRING CAKE options for ingress + egress Mapping file syntax: Each line has two whitespace separated fields, match and dscp match is one of: - tcp:<port>[-<endport>] TCP single port, or range from <port> to <endport> - udp:<port>[-<endport>] UDP single port, or range from <port> to <endport> - <ipaddr> IPv4 address, e.g. 1.1.1.1 - <ipv6addr> IPv6 address, e.g. ff01::1 - dns:<pattern> fnmatch() pattern supporting * and ? as wildcard characters - dns:/<regex> POSIX.2 extended regular expression for matching hostnames Only works, if dns lookups are passed to qosify via the add_dns_host ubus call. - dns_c:... Like dns:... but only matches cname entries dscp can be a raw value, or a codepoint like CS0 Adding a + in front of the value tells qosify to only override the DSCP value if it is zero DNS entries are compared in the order in which they are specified in the config, using the first matching entry. Planned features: - Support for LAN host based priority
