Command Prompt / Console / Windows Subsystem for Linux (WSL)

Greetings from the Windows Command-Line Teams, including the Windows Console and Windows Subsystem for Linux (WSL) teams!

We’re hear to learn about the features you’d like to see in the Windows Console (the terminal app itself), Cmd and PowerShell shells, and the Windows Subsystem for Linux (WSL) upon which several Linux distros now run!

Note: Please don’t file bugs & issues here: file issues on our GitHub repos instead:

Please DO post your asks, ideas, wants and needs for future features: We ARE listening, and we ARE grateful for your feedback!

  1. Add libusb support to WSL

    Since previous one(https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/16759696-add-usb-device-support) was marked "complete", this one more clearly states support for libusb as in any usb device raw, rather than just storage mounting and serial pass-through.
    My example need is Yubikey gpg-card.

    • WSL raw socket support for ethernet to allow for nmap functionality

      Can not run nmap from WSL due to inability to interface with network sockets. Please enable passthrough or provide documentation / support to allow configuration of ethernet sockets to work with nmap. Was lead here by this discussion: https://github.com/Microsoft/WSL/issues/2039

      • Support iptables

        Originally posted on Github around a year ago: https://github.com/Microsoft/WSL/issues/767

        Not sure how feasible this is to implement, but I've found myself in a couple of situations where it would've come in quite useful.

        • Support AF_PACKET address family (tcpdump/wireshark...)

          From https://github.com/Microsoft/BashOnWindows/issues/1628

          It would be great to get support for AF_PACKET, as some networking tools or software rely on that.

          Samples of tool that won't work without it:
          - tcpdump (socket: Invalid argument)
          - wireshark
          - some nmap functions
          - Scapy

          • Support Oracle Berkeley DB and lmdb

            Both Oracle Berkeley DB and lmdb fail on WSL as of build 18204. This is due to an issue with mmap described at https://github.com/Microsoft/WSL/issues/658 and https://github.com/Microsoft/WSL/issues/902

            Please fix the mmap issue so that lmdb and Oracle Berkeley DB, and projects relying on them, work in WSL.

            • OpenCL & CUDA GPU support

              It would be nice to have (relatively) easy access to the dedicated GPU's on our Win10 PC's, and OpenCL support for the AMD Drivers & CUDA for NVidia drivers etc.

              What I am thinking on specifically (although there are many many uses for it and CUDA support) is hashing functions that are lackluster within windows itself, but benefit immensely within Linux and Unix.

              Cryptocurrency mining for example, is known to be much faster on Linux systems than Windows. Do you see any support for OpenCL and/or CUDA in the future?

                Hey WSL users, as many of you have been asking for an update: we still do not have anything on the books yet for this feature, but we have NOT forgotten this request.

                As we navigate requirements and evaluate our WSL work, we ask that you please continue voicing your desires and upvoting this issue. Feel free to ping me on twitter @CraigWilhite to tell me more about how you’d like to see this feature in WSL.

              • Support native Docker daemon (dockerd)

                It would be great to be able to run the Docker daemon (dockerd) natively in WSL.

                Thanks for already adding support for running the Docker client in WSL.

                  • Support *BSD operating systems.

                    One of the benefits of WSL is that many server environments are Linux systems and the developer can validate many changes locally before deployment.

                    Similarly, various *BSD variants (Free-, Open-, etc.) are also frequently used on servers and developers could benefit immensely from having similar functionality.

                    This will likely be a larger item than allowing multiple Linux distributions on WSL due to the differences in system call structure.

                    • Add support for other Linux distros / meta-distributions - part two

                      After about year we have some distros in official MS magazine but we already don't have rights to install another Linux distributives.

                      I think we need to general methods of porting yourself distros to WSL.
                      It's will be easy to another people - the one idea to be popularity.

                      • Add USB Device Support

                        This ask is specifically for adding USB Device support to WSL - i.e. exposing USB busses and devices to the OS.

                        This is NOT an ask for adding the ability to communicate with external USB peripherals like phones, IoT boards, etc. - those asks are elsewhere:

                          • Make core dump files available in WSL

                            When a process crashes on WSL it does not generate a core dump, even if the necessary configuration is in place.

                            This is critical for debugging complex issues during development.

                            Referencing this issue: https://github.com/Microsoft/BashOnWindows/issues/1262

                            • Support kernel namespaces and cgroups (for Docker, headless Chrome, ...)

                              Kernel namespaces are a Linux feature that enables sandboxing (used in things like headless browsers) and containerization (i.e. Docker).

                              It would be great if WSL supported those scenarios.

                              • Add FUSE (Filesystem in Userspace) support in WSL

                                Please add FUSE (Filesystem in Userspace) interface /dev/fuse into WSL (Windows Subsystem for Linux).
                                With FUSE, we can access from WSL to file storages regularly used with Linux cluster environments such as GlusterFS, Moose FS, etc.

                                • Would love to have MTR support

                                  MTR is a very useful tool for Ops people. I would love to not have to fire up my Ubuntu VM to be able to run mtr.

                                  Currently I get "mtr: unable to get raw sockets." when attempting to run it.

                                  • Consider enabling cron jobs, daemons and background tasks

                                    Bash/WSL doesn't support cron jobs, daemons or background tasks in Win10AU. The ability to run background jobs would be very useful. Please consider adding this feature.

                                    • Add Wireless Device Support

                                      iwconfig and other wireless device tools cannot interact with wireless devices. While ifconfig, ip, etc network support has been added and displays the wireless devices (wifi0, wifi1, ...), iwconfig and other tools cannot detect wireless support. Considering the omnipresence of wifi, this makes the "Enable network connection enumeration" request feel technically fulfilled but practically half-done. Can we expect wifi support in the near future? Or are there work arounds involving the installation or compilation of particular tools?

                                      • Please enable WSL to run 32 bit ELF binaries

                                        It seems that executing 32bit ELF binaries results in "Exec format error" - guessing the kernel doesn't have 32 bit emulation support (compilation is fine, but precompiled binaries don't run). A vast number of legacy programs are still 32 bit, please add support if it won't completely destroy everything in the process - thanks!

                                        • Filesystem slow compared with native Ubuntu system.

                                          http://www.phoronix.com/scan.php?page=article&item=windows-10-lxcore&num=1

                                          Lists some benchmarks across Ubuntu and this subsystem. It is very competitive with Native Ubuntu Linux, except when it comes to filesystem access.

                                          Filesystem access is important for compilation, as well as the thousands of "watcher" js and ruby programs that constantly touch the filesystem, which are the stated target market.

                                          So, find a way to speed that up. (I don't know how you are currently mounting the filesystem, so I can't offer any ideas, other than removes as many layers as possible to the filesystem.)

                                          If you are using the ntfs systems in Linux, you might consider implementing…
