From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- drivers/char/tpm/tpm-dev.h | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 drivers/char/tpm/tpm-dev.h (limited to 'drivers/char/tpm/tpm-dev.h') diff --git a/drivers/char/tpm/tpm-dev.h b/drivers/char/tpm/tpm-dev.h new file mode 100644 index 000000000..f3742bcc7 --- /dev/null +++ b/drivers/char/tpm/tpm-dev.h @@ -0,0 +1,33 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef _TPM_DEV_H +#define _TPM_DEV_H + +#include +#include "tpm.h" + +struct file_priv { + struct tpm_chip *chip; + struct tpm_space *space; + + struct mutex buffer_mutex; + struct timer_list user_read_timer; /* user needs to claim result */ + struct work_struct timeout_work; + struct work_struct async_work; + wait_queue_head_t async_wait; + ssize_t response_length; + bool response_read; + bool command_enqueued; + + u8 data_buffer[TPM_BUFSIZE]; +}; + +void tpm_common_open(struct file *file, struct tpm_chip *chip, + struct file_priv *priv, struct tpm_space *space); +ssize_t tpm_common_read(struct file *file, char __user *buf, + size_t size, loff_t *off); +ssize_t tpm_common_write(struct file *file, const char __user *buf, + size_t size, loff_t *off); +__poll_t tpm_common_poll(struct file *file, poll_table *wait); + +void tpm_common_release(struct file *file, struct file_priv *priv); +#endif -- cgit v1.3.1
