A race condition is triggered when usermode control is given to userspace before the kernel's MSFT query responds, resulting in an unexpected response to userspace's reset command. Issue can be observed in btmon: < HCI Command: Vendor (0x3f|0x001e) plen 2 #3 [hci0] 05 01 .. @ USER Open: bt_stack_manage (privileged) version 2.22 {0x0002} [hci0] < HCI Command: Reset (0x03|0x0003) plen 0 #4 [hci0] > HCI Event: Command Complete (0x0e) plen 5 #5 [hci0] Vendor (0x3f|0x001e) ncmd 1 Status: Command Disallowed (0x0c) 05 . > HCI Event: Command Complete (0x0e) plen 4 #6 [hci0] Reset (0x03|0x0003) ncmd 2 Status: Success (0x00) Reviewed-by: Abhishek Pandit-Subedi <abhishekpandit@chromium.org> Reviewed-by: Sonny Sasaka <sonnysasaka@chromium.org> Signed-off-by: Jesse Melhuish <melhuishj@chromium.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
