This helper + * is somewhat similar to **bpf_redirect**\ (), except that it + * populates L2 addresses as well, meaning, internally, the helper + * relies on the neighbor lookup for the L2 address of the nexthop. + * + * The helper will perform a FIB lookup based on the skb's + * networking header to get the address of the next hop, unless + * this is supplied by the caller in the *params* argument.

This helper will likely be used in combination + * with helpers that adjust/change the packet size. + * + * The argument *len_diff* can be used for querying with a planned + * size change.

Providing a *len_diff* adjustment that is larger than the + * actual packet size (resulting in negative packet size) will in + * principle not exceed the MTU, which is why it is not considered + * a failure. Other BPF helpers are needed for performing the + * planned size change; therefore the responsibility for catching + * a negative packet size belongs in those helpers. + * + * Specifying *ifindex* zero means the MTU check is performed + * against the current net device. This is practical if this isn't + * used prior to redirect. + * + * On input *mtu_len* must be a valid pointer, else verifier will + * reject BPF program. If the value *mtu_len* is initialized to + * zero then the ctx packet size is use. When value *mtu_len* is + * provided as input this specify the L3 length that the MTU check + * is done against. Remember XDP and TC length operate at L2, but + * this value is L3 as this correlate to MTU and IP-header tot_len + * values which are L3 (similar behavior as bpf_fib_lookup). + * + * The Linux kernel route table can configure MTUs on a more + * specific per route level, which is not provided by this helper. + * For route level MTU checks use the **bpf_fib_lookup**\ () + * helper. + * + * *ctx* is either **struct xdp_md** for XDP programs or + * **struct sk_buff** for tc cls_act programs. + * + * The *flags* argument can be a combination of one or more of the + * following values: + * + * **BPF_MTU_CHK_SEGS** + * This flag will only works for *ctx* **struct sk_buff**. + * If packet context contains extra packet segment buffers + * (often knows as GSO skb), then MTU check is harder to + * check at this point, because in transmit path it is + * possible for the skb packet to get re-segmented + * (depending on net device features).

Userspace using &struct rfkill_event_ext and the ioctl must adhere to + * the following rules: + * + * 1. accept short writes, optionally using them to detect that it's + * running on an older kernel; + * 2. accept short reads, knowing that this means it's running on an + * older kernel; + * 3. treat reads that are as long as requested as acceptable, not + * checking against RFKILL_EVENT_SIZE_V1 or

See drivers/net/wimax/i2400m/fw.c for more - * details. - * - * The BCF data structure is for the firmware file header. - * - * - * THE DATA / CONTROL PROTOCOL - * - * This is the normal protocol spoken with the device once the - * firmware is uploaded. It transports data payloads and control - * messages back and forth. - * - * It consists 'messages' that pack one or more payloads each. The - * format is described in detail in drivers/net/wimax/i2400m/rx.c and - * tx.c. - * - * - * THE L3L4 PROTOCOL - * - * The term L3L4 refers to Layer 3 (the device), Layer 4 (the - * driver/host software). - * - * This is the control protocol used by the host to control the i2400m - * device (scan, connect, disconnect...). This is sent to / received - * as control frames. These frames consist of a header and zero or - * more TLVs with information. We call each control frame a "message". - * - * Each message is composed of: - * - * HEADER - * [TLV0 + PAYLOAD0] - * [TLV1 + PAYLOAD1] - * [...] - * [TLVN + PAYLOADN] - * - * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are - * defined by a TLV structure (Type Length Value) which is a 'header' - * (struct i2400m_tlv_hdr) and then the payload. - * - * All integers are represented as Little Endian. - * - * - REQUESTS AND EVENTS - * - * The requests can be clasified as follows: - * - * COMMAND: implies a request from the host to the device requesting - * an action being performed. The device will reply with a - * message (with the same type as the command), status and - * no (TLV) payload. Execution of a command might cause - * events (of different type) to be sent later on as - * device's state changes. - * - * GET/SET: similar to COMMAND, but will not cause other - * EVENTs. The reply, in the case of GET, will contain - * TLVs with the requested information. - * - * EVENT: asynchronous messages sent from the device, maybe as a - * consequence of previous COMMANDs but disassociated from - * them. - * - * Only one request might be pending at the same time (ie: don't - * parallelize nor post another GET request before the previous - * COMMAND has been acknowledged with it's corresponding reply by the - * device). - * - * The different requests and their formats are described below: - * - * I2400M_MT_* Message types - * I2400M_MS_* Message status (for replies, events) - * i2400m_tlv_* TLVs - * - * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the - * operation. - */ - -#ifndef __LINUX__WIMAX__I2400M_H__ -#define __LINUX__WIMAX__I2400M_H__ - -#include <linux/types.h> -#include <linux/if_ether.h> - -/* - * Host Device Interface (HDI) common to all busses - */ - -/* Boot-mode (firmware upload mode) commands */ - -/* Header for the firmware file */ -struct i2400m_bcf_hdr { - __le32 module_type; - __le32 header_len; - __le32 header_version; - __le32 module_id; - __le32 module_vendor; - __le32 date; /* BCD YYYMMDD */ - __le32 size; /* in dwords */ - __le32 key_size; /* in dwords */ - __le32 modulus_size; /* in dwords */ - __le32 exponent_size; /* in dwords */ - __u8 reserved[88]; -} __attribute__ ((packed)); - -/* Boot mode opcodes */ -enum i2400m_brh_opcode { - I2400M_BRH_READ = 1, - I2400M_BRH_WRITE = 2, - I2400M_BRH_JUMP = 3, - I2400M_BRH_SIGNED_JUMP = 8, - I2400M_BRH_HASH_PAYLOAD_ONLY = 9, -}; - -/* Boot mode command masks and stuff */ -enum i2400m_brh { - I2400M_BRH_SIGNATURE = 0xcbbc0000, - I2400M_BRH_SIGNATURE_MASK = 0xffff0000, - I2400M_BRH_SIGNATURE_SHIFT = 16, - I2400M_BRH_OPCODE_MASK = 0x0000000f, - I2400M_BRH_RESPONSE_MASK = 0x000000f0, - I2400M_BRH_RESPONSE_SHIFT = 4, - I2400M_BRH_DIRECT_ACCESS = 0x00000400, - I2400M_BRH_RESPONSE_REQUIRED = 0x00000200, - I2400M_BRH_USE_CHECKSUM = 0x00000100, -}; - - -/** - * i2400m_bootrom_header - Header for a boot-mode command - * - * @cmd: the above command descriptor - * @target_addr: where on the device memory should the action be performed. - * @data_size: for read/write, amount of data to be read/written - * @block_checksum: checksum value (if applicable) - * @payload: the beginning of data attached to this header - */ -struct i2400m_bootrom_header { - __le32 command; /* Compose with enum i2400_brh */ - __le32 target_addr; - __le32 data_size; - __le32 block_checksum; - char payload[0]; -} __attribute__ ((packed)); - - -/* - * Data / control protocol - */ - -/* Packet types for the host-device interface */ -enum i2400m_pt { - I2400M_PT_DATA = 0, - I2400M_PT_CTRL, - I2400M_PT_TRACE, /* For device debug */ - I2400M_PT_RESET_WARM, /* device reset */ - I2400M_PT_RESET_COLD, /* USB[transport] reset, like reconnect */ - I2400M_PT_EDATA, /* Extended RX data */ - I2400M_PT_ILLEGAL -}; - - -/* - * Payload for a data packet - * - * This is prefixed to each and every outgoing DATA type. - */ -struct i2400m_pl_data_hdr { - __le32 reserved; -} __attribute__((packed)); - - -/* - * Payload for an extended data packet - * - * New in fw v1.4 - * - * @reorder: if this payload has to be reorder or not (and how) - * @cs: the type of data in the packet, as defined per (802.16e - * T11.13.19.1).
