riscv: No need to relocate the dtb as it lies in the fixmap region

2023-04-30T23:26:28Z

commit 1b50f956c8fe9082bdee4a9cfd798149c52f7043 upstream. We used to access the dtb via its linear mapping address but now that the dtb early mapping was moved in the fixmap region, we can keep using this address since it is present in swapper_pg_dir, and remove the dtb relocation. Note that the relocation was wrong anyway since early_memremap() is restricted to 256K whereas the maximum fdt size is 2MB.

riscv: Do not set initial_boot_params to the linear address of the dtb

2023-04-30T23:26:28Z

commit f1581626071c8e37c58c5e8f0b4126b17172a211 upstream. early_init_dt_verify() is already called in parse_dtb() and since the dtb address does not change anymore (it is now in the fixmap region), no need to reset initial_boot_params by calling early_init_dt_verify() again.

riscv: Move early dtb mapping into the fixmap region

2023-04-30T23:26:28Z

commit ef69d2559fe91f23d27a3d6fd640b5641787d22e upstream. riscv establishes 2 virtual mappings: - early_pg_dir maps the kernel which allows to discover the system memory - swapper_pg_dir installs the final mapping (linear mapping included) We used to map the dtb in early_pg_dir using DTB_EARLY_BASE_VA, and this mapping was not carried over in swapper_pg_dir. It happens that early_init_fdt_scan_reserved_mem() must be called before swapper_pg_dir is setup otherwise we could allocate reserved memory defined in the dtb. And this function initializes reserved_mem variable with addresses that lie in the early_pg_dir dtb mapping: when those addresses are reused with swapper_pg_dir, this mapping does not exist and then we trap. The previous "fix" was incorrect as early_init_fdt_scan_reserved_mem() must be called before swapper_pg_dir is set up otherwise we could allocate in reserved memory defined in the dtb. So move the dtb mapping in the fixmap region which is established in early_pg_dir and handed over to swapper_pg_dir.

driver core: Don't require dynamic_debug for initcall_debug probe timing

2023-04-30T23:26:27Z

commit e2f06aa885081e1391916367f53bad984714b4db upstream. Don't require the use of dynamic debug (or modification of the kernel to add a #define DEBUG to the top of this file) to get the printk message about driver probe timing. This printk is only emitted when initcall_debug is enabled on the kernel commandline, and it isn't immediately obvious that you have to do something else to debug boot timing issues related to driver probe. Add a comment too so it doesn't get converted back to pr_debug().

bluetooth: Perform careful capability checks in hci_sock_ioctl()

2023-04-30T23:26:27Z

commit 25c150ac103a4ebeed0319994c742a90634ddf18 upstream. Previously, capability was checked using capable(), which verified that the caller of the ioctl system call had the required capability. In addition, the result of the check would be stored in the HCI_SOCK_TRUSTED flag, making it persistent for the socket. However, malicious programs can abuse this approach by deliberately sharing an HCI socket with a privileged task. The HCI socket will be marked as trusted when the privileged task occasionally makes an ioctl call. This problem can be solved by using sk_capable() to check capability, which ensures that not only the current task but also the socket opener has the specified capability, thus reducing the risk of privilege escalation through the previously identified vulnerability.

gpiolib: acpi: Add a ignore wakeup quirk for Clevo NL5xNU

2023-04-30T23:26:27Z

commit 782eea0c89f7d071d6b56ecfa1b8b0c81164b9be upstream. commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable") changed the policy such that I2C touchpads may be able to wake up the system by default if the system is configured as such. However on Clevo NL5xNU there is a mistake in the ACPI tables that the TP_ATTN# signal connected to GPIO 9 is configured as ActiveLow and level triggered but connected to a pull up. As soon as the system suspends the touchpad loses power and then the system wakes up. To avoid this problem, introduce a quirk for this model that will prevent the wakeup capability for being set for GPIO 9. This patch is analoge to a very similar patch for NL5xRU, just the DMI string changed.
