From 4352b8aee98005853aa63f57d6377282de17a33f Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 23 Aug 2026 13:28:57 -0700 Subject: Merge tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux Pull I3C updates from Alexandre Belloni: "A new driver this cycle, for the AMD AXI I3C controller. There are also new features such as IBI wakeup support, SETAASA device discovery and ACPI support for the the DAA methods, meaning we can now communicate with the SPD devices on DDR5 modules. New driver: - AMD AXI I3C master controller Subsystem: - I3C Common Command Code (CCC) handling improvements, especially around GET CCCs - SETAASA device discovery support - ACPI support for all existing DAA methods like SETDASA, SETNEWDA as well as I2C devices on I3C bus - IBI-based wakeup support Drivers: - dw: SETAASA support - mipi-i3c-hci: advertise IBI wakeup capability, AMD_PT I3C controller support, PIO queue management support for HCI v1.2 - renesas: improve suspend to RAM support, add runtime PM support" * tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux: (70 commits) i3c: dw: reduce do_daa time if there's no client i3c: mipi-i3c-hci: Add support for AMD_PT I3C controller i3c: mipi-i3c-hci: Add PIO queue management support for HCI v1.2 i3c: mipi-i3c-hci: Fix missing STAT_IBI_STATUS_THLD in PIO mode i3c: dw: rename "pclk" to "apb" to match dt-binding i3c: dw: make struct dw_i3c_cmd smaller i3c: dw: use COMMAND_PORT_TRANSFER_ARG instead of hardcoding i3c: renesas: Don't register devices when ENTDAA times out i3c: master: dw-i3c-master: fix OD timing for first broadcast i3c: mipi-i3c-hci: Advertise IBI wakeup capability i3c: mipi-i3c-hci: Factor out i3c_hci_sysdev() i3c: mipi-i3c-hci-pci: Propagate I3C wakeup requirements to PCI i3c: master: Reject IBI requests from non-IBI-capable devices i3c: master: Add helper to query bus wakeup requirements i3c: master: Report wakeup events for IBIs i3c: master: Support IBI-based wakeup capability i3c: master: Fix potential UAF in i3c_device_match() i3c: master: Fix potential UAF in i3c_device_uevent() i3c: Make dev->desc locking assumptions explicit i3c: master: Fix use-after-free of master->this ... --- security/integrity/evm/evm.h | 89 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 89 insertions(+) create mode 100644 security/integrity/evm/evm.h (limited to 'security/integrity/evm/evm.h') diff --git a/security/integrity/evm/evm.h b/security/integrity/evm/evm.h new file mode 100644 index 000000000..694552ace --- /dev/null +++ b/security/integrity/evm/evm.h @@ -0,0 +1,89 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +/* + * Copyright (C) 2005-2010 IBM Corporation + * + * Authors: + * Mimi Zohar + * Kylene Hall + * + * File: evm.h + */ + +#ifndef __INTEGRITY_EVM_H +#define __INTEGRITY_EVM_H + +#include +#include + +#include "../integrity.h" + +#define EVM_INIT_HMAC 0x0001 +#define EVM_INIT_X509 0x0002 +#define EVM_ALLOW_METADATA_WRITES 0x0004 +#define EVM_SIGV3_REQUIRED 0x0008 +#define EVM_SETUP_COMPLETE 0x80000000 /* userland has signaled key load */ + +#define EVM_KEY_MASK (EVM_INIT_HMAC | EVM_INIT_X509) +#define EVM_INIT_MASK (EVM_INIT_HMAC | EVM_INIT_X509 | EVM_SETUP_COMPLETE | \ + EVM_ALLOW_METADATA_WRITES | EVM_SIGV3_REQUIRED) + +struct xattr_list { + struct list_head list; + char *name; + bool enabled; +}; + +#define EVM_NEW_FILE 0x00000001 +#define EVM_IMMUTABLE_DIGSIG 0x00000002 + +/* EVM integrity metadata associated with an inode */ +struct evm_iint_cache { + unsigned long flags; + enum integrity_status evm_status:4; + struct integrity_inode_attributes metadata_inode; +}; + +extern struct lsm_blob_sizes evm_blob_sizes; + +static inline struct evm_iint_cache *evm_iint_inode(const struct inode *inode) +{ + if (unlikely(!inode->i_security)) + return NULL; + + return inode->i_security + evm_blob_sizes.lbs_inode; +} + +extern int evm_initialized; + +#define EVM_ATTR_FSUUID 0x0001 + +extern int evm_hmac_attrs; + +/* List of EVM protected security xattrs */ +extern struct list_head evm_config_xattrnames; + +struct evm_digest { + struct ima_digest_data_hdr hdr; + char digest[IMA_MAX_DIGEST_SIZE]; +} __packed; + +int evm_protected_xattr(const char *req_xattr_name); + +int evm_init_key(void); +int evm_update_evmxattr(struct dentry *dentry, + const char *req_xattr_name, + const char *req_xattr_value, + size_t req_xattr_value_len); +int evm_calc_hmac(struct dentry *dentry, const char *req_xattr_name, + const char *req_xattr_value, + size_t req_xattr_value_len, struct evm_digest *data, + struct evm_iint_cache *iint); +int evm_calc_hash(struct dentry *dentry, const char *req_xattr_name, + const char *req_xattr_value, + size_t req_xattr_value_len, char type, + struct evm_digest *data, struct evm_iint_cache *iint); +int evm_init_hmac(struct inode *inode, const struct xattr *xattrs, + char *hmac_val); +int evm_init_secfs(void); + +#endif -- cgit v1.3.1
