These are used by the USB device model, which is * defined in chapter 9 of the USB 2.0 specification and in the * Wireless USB 1.0 spec (now defunct). Linux has several APIs in C that * need these: * * - the host side Linux-USB kernel driver API; * - the "usbfs" user space API; and * - the Linux "gadget" device/peripheral side driver API. * * USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems * act either as a USB host or as a USB device. That means the host and * device side APIs benefit from working well together. * * Note all descriptors are declared '__attribute__((packed))' so that: * * [a] they never get padded, either internally (USB spec writers * probably handled that) or externally; * * [b] so that accessing bigger-than-a-bytes fields will never * generate bus errors on any platform, even when the location of * its descriptor inside a bundle isn't "naturally aligned", and * * [c] for consistency, removing all doubt even when it appears to * someone that the two other points are non-issues for that * particular descriptor type. */ #ifndef __LINUX_USB_CH9_H #define __LINUX_USB_CH9_H #include /* USB 3.2 SuperSpeed Plus phy signaling rate generation and lane count */ enum usb_ssp_rate { USB_SSP_GEN_UNKNOWN = 0, USB_SSP_GEN_2x1, USB_SSP_GEN_1x2, USB_SSP_GEN_2x2, }; struct device; extern const char *usb_ep_type_string(int ep_type); extern const char *usb_speed_string(enum usb_device_speed speed); extern enum usb_device_speed usb_get_maximum_speed(struct device *dev); extern enum usb_ssp_rate usb_get_maximum_ssp_rate(struct device *dev); extern const char *usb_state_string(enum usb_device_state state); unsigned int usb_decode_interval(const struct usb_endpoint_descriptor *epd, enum usb_device_speed speed); #ifdef CONFIG_TRACING extern const char *usb_decode_ctrl(char *str, size_t size, __u8 bRequestType, __u8 bRequest, __u16 wValue, __u16 wIndex, __u16 wLength); #endif #endif /* __LINUX_USB_CH9_H */  //* SPDX-License-Identifier: GPL-2.0-only */ /* * Copyright (C) 2011 Nokia Corporation * Copyright (C) 2011 Intel Corporation * * Author: * Dmitry Kasatkin * */ #ifndef _DIGSIG_H #define _DIGSIG_H #include enum pubkey_algo { PUBKEY_ALGO_RSA, PUBKEY_ALGO_MAX, }; enum digest_algo { DIGEST_ALGO_SHA1, DIGEST_ALGO_SHA256, DIGEST_ALGO_MAX }; struct pubkey_hdr { uint8_t version; /* key format version */ uint32_t timestamp; /* key made, always 0 for now */ uint8_t algo; uint8_t nmpi; char mpi[]; } __packed; struct signature_hdr { uint8_t version; /* signature format version */ uint32_t timestamp; /* signature made */ uint8_t algo; uint8_t hash; uint8_t keyid[8]; uint8_t nmpi; char mpi[]; } __packed; #if defined(CONFIG_SIGNATURE) || defined(CONFIG_SIGNATURE_MODULE) int digsig_verify(struct key *keyring, const char *sig, int siglen, const char *digest, int digestlen); #else static inline int digsig_verify(struct key *keyring, const char *sig, int siglen, const char *digest, int digestlen) { return -EOPNOTSUPP; } #endif /* CONFIG_SIGNATURE */ #endif /* _DIGSIG_H */ #lY>eJpS ik?ELF>(@@8 @@@@00 kkd` 88800hhhDDStd8
