Linux kernel modifications for the Kernel Hacking exam

The old document for usbip protocol is misleading and hard to read: * Some fields in header are incorrect * Explanation of some fields are unclear or even wrong * Padding of header (namely all headers have the same length) is not explicitly pointed out, which is crucial for stream protocol like TCP Major changes: * Document the correct field as described in the codebase. * Document the padding in usbip headers. This is crucial for TCP stream hence these padding should be explicitly point out. In code these padding are implemented by a union of all headers. * Fix two FIXME related to usbip unlink and Document the behavior of unlink in different situation. * Clarify some field with more accurate explanation, like those fields associated with URB. Some constraints are extracted from code. * Delete specific transfer_flag doc in usbip as it should be documented by the URB doc in Documentation/driver-api/usb/URB.rst * Add data captured from wire as example Version change: From "PRELIMINARY DRAFT, MAY CONTAIN MISTAKES, 28 Jun 2011" To "Version 1, 31 Mar 2021" Co-developed-by: Alexandre Demers <alexandre.f.demers@gmail.com> Reviewed-by: Randy Dunlap <rdunlap@infradead.org> Reviewed-by: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: Hongren Zheng <i@zenithal.me> Link: https://lore.kernel.org/r/YGNZHfmAbHO6fyAr@Sun Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.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.
