[20091107] NetBSD vs. Microkernels - From Kernel to Userspace and Abroad
A few weeks ago I made a comment about NetBSD not being a "microkernel" despite it's move to kernel modules. Antti Kantee wrote back to me (Hi Antti!) reminding me of his work on RUMP, PUFFS and the like, which I think does definitely deserve mentioning in that context:

With RUMP, PUFFS and the like, Antti is set on a mission to define interfaces between kernel components, and move those kernel components from inside the kernel to the userland. As a result, the (once) kernel-code is now running as "simple" userland processes that have all the benefits like memory protection and not taking down the whole system in case of an error. Examples that Antti has been bashing on started with moving file systems to the userland, which resulted in PUFFS and ReFUSE, an implementation of the Linux inferface of File systems in USErland (FUSE). Not stopping at file systems (which are traditionally used for accessing data on storage media, like e.g. for ntfs-3g), Antti went further and moved into getting network services like SSHFS going - in userland, based on FUSE.

Not stopping there, more recent works include:

Remember when NetBSD got (re)FUSE? All of a sudden we got a bazillion of filesystems back then. So why not turn this development around, and make RUMP available as an interface for all sort of drivers to other operating systems. That way, they can get our file systems, usb stack and drivers, etc., and run them in userspace as well. Developing a driver on one operating system, and using it on many - a wet dream would come true!

Sounds impossible? Ye fear not, it's been done! Arnaud 'stacktic' Ysmal already has ported RUMP to FreeBSD and Linux, the work is available via pkgsrc/misc/rump, and there is also Arnaud's page on Rump on non-NetBSD Operating Systems for more information.

Whew... lots of research and development going on in this area, and - getting back to the initial topic - we may well see an operating system in the future that moves from the monolithic to a microkernel approach, and it may or may not be called NetBSD. Fact is, that a lot of research is going on in that area, on NetBSD, here and now. Hats off, Antti!

[20091014] Catching up: Webfwlog, git, vnd and sparse disk images, acpismbus
Here are two news items from the past few days:
  • Web-based firewall log reporting and analysis tool Webfwlog 0.94 released: ``Webfwlog is a flexible web-based firewall log analyzer and reporting tool. It supports standard system logs for linux, FreeBSD, OpenBSD, NetBSD, Solaris, Irix, OS X, etc. as well as Windows XP. Supported log file formats are netfilter, ipfilter, ipfw, ipchains and Windows XP. [...]

    With Webfwlog you can design reports to use on your logged data in whatever configuration you desire. Included are example reports as a starting point. You can sort a report with a single click, "drill-down" on the reports all the way to the packet level, and save your reports for later use. You can also create a link directly to any saved report.''

    See the webfwlog homepage for more information.

  • Git copies of cvs modules available - spz@ writes that ``htdocs, othersrc, pkgsrc, src and xsrc are now available as (bare) git repository copies at These repositories are currently updated every 30 minutes.

    They are not authoritative and are not meant to replace cvs, but if you want to track your development that is not yet fit for committing into cvs head or sending in as a PR, and want to use git for that, they may serve as a convenient starting point or reference.''

  • Support for writing file systems on sparse disk images - File system hacker Antti Kantee writes: ``Yesterday I wanted to write to a file system which was on a sparse disk image. Normally I would have just used a rump mount, but since the file system was not at offset = 0 in the file, this failed. vnd wasn't helpful either: it allowed me to mount the image and then I got weird errors when writing.

    I just finished adding disklabel support to the various rump_fs utilities. Due to them using the option parsing code of the real mount_fs utilities, I decided to signal the label number with a magic parameter at the end of the device (yes, this really simplifies things currently).

    Let's assume you're looking at wd0.img. Here's how it works:

    === SNIP ===
    golem> disklabel wd0.img
    16 partitions:
    #        size    offset     fstype [fsize bsize cpg/sgs]
     a:    719712        63     4.2BSD   1024  8192     0  # (Cyl.      0*-    714*)
     b:     66657    719775       swap                     # (Cyl.    714*-    780*)
     c:    786369        63     unused      0     0        # (Cyl.      0*-    780*)
     d:    786432         0     unused      0     0        # (Cyl.      0 -    780*)
    golem> rump_ffs wd0.img%PART:a% /puffs
    rump_ffs: "wd0.img" is a non-resolved or relative path.
    rump_ffs: using "/usr/home/pooka/wd0.img" instead.
    golem> df /puffs
    Filesystem                      1K-blocks       Used      Avail %Cap Mounted on
    /usr/home/pooka/wd0.img%PART:a%     338471     256211      65337  79% /puffs
    === SNIP ===
    So you specify the partition number as %PART:n%, where is n is obviously the partition number. Other than that, things work as usual. No vnconfig etc. necessary.

  • New ACPI driver: acpismbus(4) - call for testers - Paul Goyette writes that ``At the request of some folks off-list, I have created a driver for ACPI's SMBus Control Method Interface. Basically, this is an acpi-based wrapper to provide device-independant access to i2c/SMBus controllers. (See spec at for further info.)

    To see if your system can use this driver, check the output of acpidump for the existence of a Device(SMB0). If you have an SMB device, I'd appreciate it if you could help test this driver!''

    Continue with Paul's mail to learn on how to test the driver, and what limitations there are currently.

[20081114] Catching up - what happened in NetBSD-land between mid-August and mid-November
OK, I've been slacking^Wbusy for the past weeks, but I hope things will get a bit better now. For a start, here's a catch-up of the things that accumulated in my inbox in the past ~two months:
  • Google Summer of Code is over for some time, but apparantly no final report has emerged so far (shame!). Still, a number of individual status reports came by on the official lists:

    I know of at least one other project (uvc) that has completed but that I didn't see a report here - maybe I've missed it. Anyways, GSoC was another big success this year. Thanks, Google!

  • Speaking of Adam Hamsik and Logical Volume Management (LVM), Adam has continued his work in that are, and he has written a device mapping library that interacts with his kernel driver. This allows to interact with his GSoC project without using any GPL code! See Adam's posting for more details.

  • Force 10 Networks, producer of 10gbit switches that use an operating system based on NetBSD, have added a new feature as part of their FTOS operating system: VirtualView, which provides virtualization of Force 10 based equipment. From the xchange article: ``Force10 Networks Inc. this week introduced VirtualView software for benchmaking, troubleshooting and managing virtualized environments based on Force10 gear.''

    More information is available from the Force 10 Networks homepage, plus in articles by, light reading, Zycko, and SmartBrief.

  • Following the latest hype in portable computers, NetBSD has created a netbook page that intends to list models and the extent to which they are supported. Your contributions are most welcome here! (Contact me for sending updates and hardware :-)

  • Zafer Aydogan has made RSS feeds available for CVS commits to single files - see his mail to netbsd-users for more details.

  • New security advisory were released that I've missed in my last update:

  • A project that's been ongoing for quite some time is the move from "old-school" loadable kernel modules (LKMs) to new-style kernel modules. Important changes include the fact that modules can be either linked into the kernel at build time, or loaded into the kernel at runtime from the same file. Also, the bootloader was modified to load modules after the kernel, e.g. for a RAM-disk like the one that is used by the INSTALL kernel.

    In the same line, some parts are starting to be moved out of the GENERIC kernel, and installed as modules that can be loaded by the new framework then. The start is made by POSIX semaphores as a first step and proof-of concept, even if some details are still under hot debate, e.g. what the file system layout for modules is, and if the belong to the kernel and its build process, or to the userland.

  • While talking about splitting the kernel into modules, Antti Kantee has continued his work to move parts of the kernel into userspace, in particular running file system code as userland in his RUMP, and puffs and (Re)FUSE works. The idea is to provide the interfaces that file systems need in the userland, and the result is that you can run code that used to run inside the kernel in userland now.

    Another subsystem running in the kernel that could be moved to userland by providing appropriate interfaces with the rest of the kernel is the network stack, and Antti has moved just that to the userland. See Antti's mail to tech-net@ for more information on this impressive work.

  • NetBSD has shipped XFree in previous releases, and people who wanted to use had to install it from pkgsrc. That's all fine, but to get a modern X, one had to compile things, as no precompiled binary packages are made available for many platforms. This is changing now, and NetBSD is getting integrated via a reachover infrastructure which is also enabled for crosscompiling.

    The "user interface" for this is still in flux, but after some detour (" -V MKXORG=yes", without -x), " -x" now builds whatever X is considered the default for the platform. Some platforms already default to use as X, and more will come, as changes that were made to NetBSD's copy of XFree are adopted to

    Platforms that use by default now are macppc (see here and here), sparc sparc64, shark, amd64 and i386.

    As is at Revision 7 now, it's installed in /usr/X11R7, which will lead to a lot of interesting effects. pkgsrc is already prepared for the new layout, but there are still many minor details that will need adjusting to the new directory. If you find one, post your patches to tech-x11.

  • Besides the GNU C compiler, there's the BSD-licensed Portable C Compiler around for some time now. It doesn't offer the same support as its GNU cousin yet, but this may change now: The BSD Fund is currently doing a fund drive to get money to enhance PCC. The goal is to raise $12,000US to improve support for core compiler functionality as well as support for C99, gcc compatibility and the amd64 architecture. See the project page for further details.

  • The NetBSD 5.0 release cycle has started! There's a netbsd-5 branch in CVS, daily binaries are available for testing, and some of the highlights of the upcoming release include file system journalling for FFS via WAPBL, and

    To help testing of NetBSD on Cobalt machines, Izumi Tsutsui has made a NetBSD 5.0_BETA based version of the Cobalt restore CD available. Enjoy!

  • As the final point today, a word on NUMA support from Christoph Egger. Non-Uniform Memory Access is needed in massive parallel systems where some nodes have RAM more tightly associated than others, where the RAM is further away, resulting in different access times for different regions of memory. In order to support this, Christop Egger has made first steps.

    His example implementation uses information from ACPI, and shows some heavy dmesg-pr0n from a 16-core machine with four sockets. Yumm!

So much for today. With the NetBSD 5.0 release cycle started, I'd like to encourage everyone to test the release branch, report errors, send patches as well as beer and choccolate to make this the best release that we've ever had.

[20080428] Recent development related to puffs, ReFUSE, rump, and more (Updated)
NetBSD's kernel is under very active development these days, and while many changes are related to improve SMP, it's not the only area. An area where very interesting and unique work is being done is the filesystem interfaces that Antti Kantee is working. Things started out as a past year's Google "userfs" SoC project to implement an interface for running filesystem code in userland. The project was imported into NetBSD some time ago. On top of that, a library that mimics the Linux interface for filesystems in userland. Following the Linux name FUSE, the re-implementation is called ReFUSE (pun intended :). See the webpage about puffs, refuse, FUSE on the NetBSD website for more information.

Another project that was started by Antti after his work to run filesystem code in userland is "rump". The project allows to use "ordinary" filesystems that usually run inside the kernel, and mimic an environment similar to what's available inside the kernel, and move the whole filesystem into userland - verbatime, with no code changes! This allows to develop filesystem code in userland, and later on move it inside the kernel with no further changes - a bit step forward for filesystem development!

This all sounds rather easy, but as filesystems need to move data between storage and memory, a big issue in filesystems is interfacing with the virtual memory subsystem, and adding interfaces like puffs and ReFUSE also needs to consider VM for efficient transfers and caching.

Work in this area is still ongoing, and I've asked Antti about his recent achievements in this area[1]. While the only user-visible change is caching and performance improvements in the Secure Shell filesystem's handler "mount_psshfs", most of the changes are on the inside. Antti wrote me: ``The interesting ones from a programmer's perspective are probably:

  • Splitting userspace transport out of puffs in the kernel (putter)
  • Using putter to implement support for userspace block/char device drivers (pud). pud does still not have a userspace library similar to libpuffs. libpuffs needs to become libputter and lib{puffs,pud}.

  • Removing special case handling for the puffs user/kernel protocol transport. This means that file system requests can now be read/written like any other protocol. This is covered in the AsiaBSDCon 2008 paper "Send and Receive of File System Protocols: Userspace Approach With puffs"

    With some minor work in libpuffs, it possible to e.g. do an ffs mount from a remote site with the help of rump.

Finally, while not really useful for anything except puffs development, I think the following is cool from the perspective of completeness:

  • Add support to rump to be able to run the puffs kernel module in userspace. This means that that *any* puffs file system (incl. rump ones) can be mounted so that requests pass once through the puffs kernel module running in the kernel and once through the puffs kernel module running in userspace before being delivered to the file system driver. Example:
      sys/rump/fs/bin/syspuffs> ./syspuffs mount_psshfs server.address /path 

With puffs and rump, there are two very interesting and active projects doing research in filesystems on NetBSD, which may lead to changes in the way filesystems are understood in the Unix world. While there, a third project that may be worth watching in this regards is this year's Google hurdt Summer of Code project by Marek Dopiera, which aims at implementing Hurd translators for NetBSD,

Update: Antti dropped me a note that another project related to filesystems is this year's "fs-utils" SoC project. The goal is to create a userland tool to manipulate filesystem images, and the idea is to reuse kernel code with the ukfs library. That way, no redundancy between kernel sources and userland sources are created, and both areas benefit from mutual testing and code maturity.

[20070806] RUMP - Userspace kernel file system framework
One of this year's summer-of-Code projects is Antti Kantee's Userspace Kernel File System framework, which has the goal of creating an interface to run file system code in userspace. Antti did a lot of work in his previous Userspace filesystem hooks which also resulted in puffs and (re)fuse.

This year's project goes one step further as not only the VFS operations are passed from kernel to userspace, but the full filesystem code is ran in userspace, including memory management (buffer cache!). This allows developing filesystem code in userland with the "normal" kernel interfaces, but no panics if something goes wrong -- a simple core dump, and that's it. To cite from Antti's mail: ``If you want to give it a whirl, upgrade, go to sys/rump, type "make", go to fs/bin/$foofs and run the file system. It should work to a certain degree provided your system comes with puffs. Does it do anything a kernel file system wouldn't do? No .. except the core dump may be smaller and faster and less intrusive. Oh, actually it does one cool trick: you can run it on non-block devices, so you don't need to vnconfig the file system image first (provided, of course, that the file system starts right from the beginning of the image and that you wouldn't need a disklabel).''

For more information, see Antti's first and second email and his Summer-of-Code project page.

[20070313] Filesystems in User-Space: puffs, refuse vs. FUSE, and more (Updated)

[I'm taking the liberty to post this unquoted here, as I did the editing on the news item, based on input from Antti and Al]

NetBSD now offers full support for running file systems in userspace. The core component inside the kernel that exposes a file system interface towards the userland programs is "puffs", and communicates with vnodes, the kernel's own idea of files. The "libpuffs" library is the interface between userland file systems and the kernel component. To facilitate running the huge amount of file systems already available for the FUSE interface, but not dictate the capabilities of puffs by it, it was decided that FUSE support should be provided as a compatibility layer on top of the native puffs interface. This compatibility is offered by re-fuse, a BSD-licensed re-implementation of FUSE. It is designed to be source code compatible with FUSE, and more information can be found in the refuse(3) manpage.

While puffs is stable for users, the library programming interface and the binary interfaces are still likely to change, and therefore puffs and the dependant librefuse are not built by default. For people tracking -current, the build of all relevant puffs components (librefuse, psshfs, etc.) by "make build" can be enabled by adding "MKPUFFS=yes" to /etc/mk.conf. Using puffs also requires the kernel option "file-system PUFFS", or alternatively loading the puffs.o kernel module, which is included in a puffs-enabled build.

FUSE compatibility was added within pkgsrc, and besides the required infrastructure work a number of FUSE packages were added to pkgsrc in the new "filesystem" category. Example packages that are currently available include:

puffs was originally developed during the Google Summer of Code 2005 "userfs" project by Antti Kantee. It was further polished using funding from the Ulla Tuominen Foundation and committed into the NetBSD source tree in October 2006. The work was presented at AsiaBSDCon 2007 in a paper entitled "puffs - Pass-to-Userspace Framework File System". The "refuse" library was written by Alistair Crooks and committed to NetBSD in February 2007. All components will be available in NetBSD releases starting with NetBSD 5. Work for using FUSE-enabled packages via pkgsrc was done by Juan Romero Pardines following import of the "refuse" library.

For more information, see NetBSD's webpage on file systems in userspace at

Update: An in-depth technical description of puffs was presented at AsiaBSDCon 2007 in a paper entitled "puffs - Pass-to-Userspace Framework File System". The paper and slides are available.

[20070221] ReFUSE - Linux-compatible filesystem in userspace interface
After Antti Kantee has picked up his previous userfs: Userspace file system hooks Summer-of-Code project, it has since been integrated into NetBSD, together with a small number of example filesystems -- see my previous report on ssshfs.

Now while having a new interface for filesystems in userspace is all nice and dandy, there's already such a thing which (of course) differs in details and is not compatible with the puffs interface: Linux' Filesystem in Userspace (FUSE). Alistair Crooks has sat down and implemented "refuse", a FUSE-compat library for puffs that allows using Linux FUSE filesystems with NetBSD's puffs.

After compatibility with Linux on the source level was realized, FUSE-based filesystems can be ported to NetBSD easily, and a separate category was created for them in NetBSD's Packages System: pkgsrc/filesystems (link will work shortly ;). Packages that are available right now:

  • fuse: Filesystem in Userspace (compat headers, pkg-config files, etc.), needed for pkgsrc on Linux
  • fuse-archivemount: FUSE gateway to libarchive
  • fuse-cddfs: FUSE filesystem that uses libparanoia for audio CDs
  • fuse-cryptofs: FUSE encrypted filesystem
  • fuse-curlftpfs: FUSE filesystem for acessing FTP hosts
  • fuse-httpfs: FUSE HTTP filesystem
  • fuse-lzofs: Filesystem which allows you to transparently use compressed files
Much of the work on pkgsrc was done by Juan 'xtraeme' Romero Pardines, who also told me about his (spanish-language) blog.

Please note that this is an area where heavy development is still going on, and that this work is only available on NetBSD-current. Upcoming work that we can look forward for are improvements on FUSE compatibility and a port of the ntfs-3g filesystem, an open source, freely available NTFS driver for Linux with read and write support. Many more FUSE modules/filesystems are available, so it can be expected that there's more to come.

[20061123] ssshfs success (Updated)
I've taken the existance of ssshfs as a reason for upgrading my kernel from the netbsd-4 branch (which will go through re-birth from -current soon anyways) to today's -current, and played with ssshfs a bit. As I didn't want to upgrade the full userland of the machine, I had to do a bit of a dance to get things going in src/obj/destdir, but after
  • chroot .../src/obj/destdir
  • cd .../src/obj/destdir/dev ; sh MAKEDEV all puffs
  • cd .../src/share/examples/puffs/ssshfs ; make
  • ./ssshfs i@remotemachine:/path/to/my/home /mnt
things work fine, and I can access my $HOME on the remote machine just like a local file (esp. from outside the chroot):
miyu% df | grep destdir
puffs:ssshfs  0 0 0   100%    /usr/src/obj/destdir/mnt
miyu% cd /usr/src/obj/destdir/mnt
miyu% ls
AdobeFnt.lst    OS                  bin     public_html
Desktop         OpenOffice.org1.1.0 in      tmp
miyu% ls -l .cshrc

miyu% head -2 .cshrc
# Default .cshrc fuer Solaris, Irix, ...
miyu% md5 .cshrc
MD5 (.cshrc) = 2ad1d2606a5678f312709a388376c2e5
miyu% ls -l test
ls: test: No such file or directory
miyu% date >test
miyu% ls -l test
-rw-r--r--  1 39068  2000  29 Nov 23 01:19 test
miyu% cat test

miyu% cat test
Thu Nov 23 01:19:36 MET 2006
hubertf was here
miyu% rm test
miyu% cat test
cat: test: No such file or directory
Neat! I've found one bug when running stat(2) -- e.g. via ls -l -- on a symlink. ssshfs then hangs and the mounting process needs to be ^Cd, but I'm sure this is not a major problem.

Update: The cause of the hang was identified: I tried this against Solaris 9, which has a sshd that only supports the SFTP File Transport Protocol Version2, but to properly handle symlinks Version 3 is needed. A check for the protocol version was added, to indicate the case can't be handled.

[20061123] Digest: ssshfs, NAMP VMware image, Segvguard, BSDtalk and a daemonic bag
OK, I'm too lazy to put this into separate items, so here's the stuff from today in one digest:
  • There was some progress on puffs, the userland filesystem stemming from last year's Google SoC, some time ago. More example userland filesystems are now available with sysctlfs and ssshfs, see src/share/examples/puffs.

    Rumours say that ssshfs works pretty well, which is a final reason to ditch the (abandoned first cut of the) netbsd-4 branch and make a -current kernel to play with this. BTW, for those wondering what ssshfs is, see ssshfs.c:

     * simple sshfs
     * (silly sshfs?  stupid sshfs?  snappy sshfs?  sucky sshfs?  seven sshfs???)
     * (sante sshfs?  severed (dreams) sshfs?  saucy sshfs?  sauerkraut sshfs?) 

  • People complained that there's no ready-made VMware image with NetBSD available, and this has changed now. The #NetBSD blog points at a NAMP (NetBSD + Apache + MySQL + PostgreSQL + PHP) image that has quite a lot of software installed in 187MB size. See the arudius homepage for more information on NAMP.

  • Elad, chief security hacker of NetBSD's infrastructure has proposed to add PaX Segvguard as yet another building stone in NetBSD's security architecture:
         PaX Segvguard monitors the number of segfaults in a program
         per-user, in an attempt to detect on-going exploitation attempts
         and possibly prevent them.  One common attack PaX Segvguard can
         help mitigate is when an attacker tries to brute-force a function
         return address, when wanting to perform a return-to-lib attack.  

    See Elad's proposal for more details! Note that a start of the implementation is already in NetBSD-current, but that this is still work-in-progress.

  • BSDtalk did an interview with pkgsrc developer Johnny Lam (jlam@), it's available in mp3 and ogg.

  • Last, if you don't know what to wish for Xmas, there's something for the average BSD geek: a daemon-themed bag (which is probably not really authorized by the Daemon owner, but well).
