BugLink: https://bugs.launchpad.net/bugs/1854855 [ Upstream commit 09015855 ] Upon success the update_status handler returns a positive number corresponding to the number of bytes transferred by usb_control_msg. However the return code of the update_status handler should indicate if an error occurred(negative) or how many bytes of the user's input to sysfs that was consumed. Return code zero indicates all bytes were consumed. The bug can for example result in the update_status handler being called twice, the second time with only the "unconsumed" part of the user's input to sysfs. Effectively setting an incorrect brightness. Change the update_status handler to return zero for all successful transactions and forward usb_control_msg's error code upon failure.

BugLink: https://bugs.launchpad.net/bugs/1854855 [ Upstream commit c2712b85 ] Andy had some concerns about using regs_get_kernel_stack_nth() in a new function regs_get_kernel_argument() as if there's any error in the stack code, it could cause a bad memory access. To be on the safe side, call probe_kernel_read() on the stack address to be extra careful in accessing the memory. A helper function, regs_get_kernel_stack_nth_addr(), was added to just return the stack address (or NULL if not on the stack), that will be used to find the address (and could be used by other functions) and read the address with kernel_probe_read().

BugLink: https://bugs.launchpad.net/bugs/1854855 [ Upstream commit 6b995f4e ] In _scif_prog_signal(), the boolean variable 'x100' is used to indicate whether the MIC Coprocessor is X100. If 'x100' is true, the status descriptor will be used to write the value to the destination. Otherwise, a DMA pool will be allocated for this purpose. Specifically, if the DMA pool is allocated successfully, two memory addresses will be returned. One is for the CPU and the other is for the device to access the DMA pool. The former is stored to the variable 'status' and the latter is stored to the variable 'src'. After the allocation, the address in 'src' is saved to 'status->src_dma_addr', which is actually in the DMA pool, and 'src' is then modified. Later on, if an error occurs, the execution flow will transfer to the label 'dma_fail', which will check 'x100' and free up the allocated DMA pool if 'x100' is false. The point here is that 'status->src_dma_addr' is used for freeing up the DMA pool. As mentioned before, 'status->src_dma_addr' is in the DMA pool. And thus, the device is able to modify this data. This can potentially cause failures when freeing up the DMA pool because of the modified device address. This patch avoids the above issue by using the variable 'src' (with necessary calculation) to free up the DMA pool.

BugLink: https://bugs.launchpad.net/bugs/1854855 [ Upstream commit 655603de ] The sysfs handler should return the number of bytes consumed, which in the case of a successful write is the entire buffer. Also fix a bug where param.data_len was being set to (count - (2 * sizeof(u32))) instead of just (count - sizeof(u32)). The latter is correct because we skip over the leading u32 which is our param.type, but we were also incorrectly subtracting sizeof(u32) on the line where we were actually setting param.data_len: param.data_len = count - sizeof(u32); This meant that for our example event.kernel_software_watchdog with total length 10 bytes, param.data_len was just 2 prior to this change.

Since setup_log_buf() is called during early init, logbuf is mostly empty, so __LOG_BUF_LEN - log_next_idx is close to 1<<25. Thus when we multiply it by 100, we overflow signed integer value range: 100 is 2^6 + 2^5 + 2^2. Example, booting with LOG_BUF_LEN 1<<25 and log_buf_len=2G boot param: [ 0.075317] log_buf_len: -2147483648 bytes [ 0.075319] early log buf free: 33549896(-28%) Make "free" unsigned integer and use appropriate printk() specifier.

BugLink: https://bugs.launchpad.net/bugs/1854855 [ Upstream commit ea893695 ] A recent bugfix added a call to i8042_install_filter but did not add the dependency, leading to possible link errors: drivers/platform/built-in.o: In function `asus_nb_wmi_quirks': asus-nb-wmi.c:(.text+0x23af): undefined reference to `i8042_install_filter' This adds a dependency on SERIO_I8042||SERIO_I8042=n to indicate that we can build the driver when the i8042 driver is disabled, but it cannot be built-in when that is a loadable module.

BugLink: https://bugs.launchpad.net/bugs/1854855 [ Upstream commit db2582af ] This patch adds support for ALS on the Zenbook UX430UQ to the asus_nb_wmi driver. It also renames "quirk_asus_ux330uak" to "quirk_asus_forceals" because it is now used for more than one model of computer, and should thus have a more general name.

This patch will do the same. Turn ALS on by default.

BugLink: https://bugs.launchpad.net/bugs/1854855 [ Upstream commit b5643539 ] Some revisions of the ASUS Q500A series have a keyboard related issue which is reproducible only after Windows with installed ASUS tools is started. In this case the Linux side will have a blocked keyboard or report incorrect or incomplete hotkey events. To make Linux work properly again, a complete power down (unplug power supply and remove battery) is needed. Linux/atkbd after a clean start will get the following code on VOLUME_UP key: {0xe0, 0x30, 0xe0, 0xb0}. After Windows, the same key will generate this codes: {0xe1, 0x23, 0xe0, 0x30, 0xe0, 0xb0}. As result atkdb will be confused by buggy codes.
