Some distributions have turned on the reset attack mitigation feature, which is designed to force the platform to clear the contents of RAM if the machine is shut down uncleanly. However, in order for the platform to be able to determine whether the shutdown was clean or not, userspace has to be configured to clear the MemoryOverwriteRequest flag on shutdown - otherwise the firmware will end up clearing RAM on every reboot, which is unnecessarily time consuming. Add some additional clarity to the kconfig text to reduce the risk of systems being configured this way.

Quoting Hans: If we return 1 from our post_reset handler, then our disconnect handler will be called immediately afterwards. Since pre_reset blocks all scsi requests our disconnect handler will then hang in the scsi_remove_host call. This is esp. bad because our disconnect handler hanging for ever also stops the USB subsys from enumerating any new USB devices, causes commands like lsusb to hang, etc. In practice this happens when unplugging some uas devices because the hub code may see the device as needing a warm-reset and calls usb_reset_device before seeing the disconnect. In this case uas_configure_endpoints fails with -ENODEV. We do not want to print an error for this, so this commit also silences the shost_printk for -ENODEV. ENDQUOTE However, if we do that we better drop any unconditional execution and report to the SCSI subsystem that we have undergone a reset but we are not operational now.

[Linux-stable-mirror] Patch "USB: serial: io_edgeport: fix possible sleep-in-atomic" has been added to the 4.15-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: io_edgeport: fix possible sleep-in-atomic to the 4.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: usb-serial-io_edgeport-fix-possible-sleep-in-atomic.patch and it can be found in the queue-4.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From c7b8f77872c73f69a16528a9eb87afefcccdc18b Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai <baijiaju1990(a)gmail.com> Date: Wed, 13 Dec 2017 20:34:36 +0800 Subject: USB: serial: io_edgeport: fix possible sleep-in-atomic From: Jia-Ju Bai <baijiaju1990(a)gmail.com> commit c7b8f77872c73f69a16528a9eb87afefcccdc18b upstream. According to drivers/usb/serial/io_edgeport.c, the driver may sleep under a spinlock. The function call path is: edge_bulk_in_callback (acquire the spinlock) process_rcvd_data process_rcvd_status change_port_settings send_iosp_ext_cmd write_cmd_usb usb_kill_urb --> may sleep To fix it, the redundant usb_kill_urb() is removed from the error path after usb_submit_urb() fails. This possible bug is found by my static analysis tool (DSAC) and checked by my code review.
