8c0cdf29 1# DragonFly Projects
b790f880 2
8c0cdf29 3This page shall serve as a common place to look if you're in search of a DragonFly related project. It's also the place to check if someone else is already working on it (to prevent project collision) or should be contacted.

8c0cdf29 22## Documentation projects
b790f880 23
8c0cdf29 24* Check all chapters of the handbook and do the following:
8c0cdf29 25* Check if the content applies to DragonFly. If not, change it.
8c0cdf29 26* Add new content and enhance the previous chapters
8c0cdf29 27* Check for syntax error, typos and wiki errors.
8c0cdf29 28* Add prev/next buttons to all pages.
8c0cdf29 29* Reorder `/usr/src/UPDATING` to put more relevant information at top; remove data no longer relevant.
193c08af 30* Help out in [http://bugs.dragonflybsd.org](http://bugs.dragonflybsd.org) (try to reproduce, diagnose, propose fixes ...)
8c0cdf29 31* Organize, contribute to, and finish the C book project.
193c08af 32
8c0cdf29 33## Userland projects
b790f880 34
193c08af 35* Bring in BSD-licensed versions of some text tools like `grep`, `diff` and `sort`. The OpenBSD guys already did some work related to that. If you manage to bring the tools to DragonFly, check if everything works as expected (e.g. rc.d scripts, make world runs, ...). Of course the new tools need to have at least all the features of the old GNU tools.
48ae8f2c 36* Update the [[contributed software|docs/user/ContribSoftware]] which is out-of-date.
8c0cdf29 37* Remove `NOINET6` build option
8c0cdf29 38* `WARN` corrections to utilities
8c0cdf29 39* Clean our code to make it [style(9)](http://leaf.dragonflybsd.org/cgi/web-man?command#style&sectionANY) compatible. Compile and test your changes. Verify that the checksum (sha(1)) of the unmodified object matches the checksum of the cleaned object. Check also with strip(1)+sha(1)
8c0cdf29 40* Bring in code from other *BSDs:
8c0cdf29 41* smbfs changes from FreeBSD
8c0cdf29 42* pf changes from OpenBSD
193c08af 43* Randomize mmap() offsets as described in [http://www.openbsd.org/papers/ven05-deraadt/index.html](http://www.openbsd.org/papers/ven05-deraadt/index.html)
8c0cdf29 44* Add extended slice support to `fdisk`
8c0cdf29 45* Install Coverity and fix the FreeBSD bugs that were uncovered by Coverity, but do not just blindly pull over the FreeBSD patches. Make sure that you first understand what the patch does.
193c08af 46* C99 Standards Conformance. The todo list is on [[/docs/developer/StandardsConformanceProject]] (original [http://www.in-nomine.org/~asmodai/df/conformance/](http://www.in-nomine.org/~asmodai/df/conformance/)).
8c0cdf29 47* Setup a regression testing machine/system to register and find problems and new improvements..
8c0cdf29 48* Networking performance scalability
193c08af 49* scalability (algorithmic performance) - ideas: [http://bulk.fefe.de/scalability/](http://bulk.fefe.de/scalability/) and [http://bulk.fefe.de/lk2006/talk.pdf](http://bulk.fefe.de/lk2006/talk.pdf)
50* [[RegressionTest|/docs/developer/RegressionTest]]
51* also check [[HowToStressTest|/docs/developer/HowToStressTest]]
8c0cdf29 52* Add lwp support to ptrace/gdb/core dumps.
193c08af 53* [[/docs/developer/CheckpointFeatures]]
54* Linuxulator update (FreeBSD did a lot of work in this area. Look [here](http://wiki.freebsd.org/linux-kernel),
8c0cdf29 55* Bringing in version 2.0 of the BSD Installer
193c08af 56* Build a Live CD with a DragonFly-specific X desktop, integrated into nrelease build. Check ongoing LiveDVD project: [[LiveDVD for Google SoC|/docs/developer/LiveDVDGSoC]]
8c0cdf29 57* UTF8 support in the console
8c0cdf29 58* Write a tool to monitor changes in other code bases such as FreeBSD, NetBSD, OpenBSD. corecode is busy with this one (http://oly.corecode.ath.cx/~corecode/cgi-bin/crosscgi.py) (svn repository (https://fortunaty.net/svn/crossref/)).
8c0cdf29 59* Work relating GDB:
18741101 60 * ptrace/gdb follow-fork-mode support and more (peek at linux)
61 * Change the build to create one libbfd for gdb and binutils
62 * Separate RPC code from NFS into separate library.
8c0cdf29 63
64## Kernel projects
65
8c0cdf29 66* Make our sound system support surround sound
8c0cdf29 67* Port the BSDL OSS code to DragonFly
8c0cdf29 68* Complete Path MTU Discovery by adding a host route to remember the Path MTU and setting a timer to expire old host routes. See netinet/if_ether.c for an example of this mechanism as used by ARP. Periodically increase MTU of hosts that have had its MTU decreased.
8c0cdf29 69* Look for places in the kernel that can benefit from Solaris-style caching of preconstructed slab allocator objects. If we can find enough of these uses, we can add this functionality to the kernel memory allocator.
421e78f1 70* Implement [`sem_open()`](http://www.opengroup.org/onlinepubs/000095399/functions/sem_open.html), [`sem_close()`](http://www.opengroup.org/onlinepubs/000095399/functions/sem_close.html), and [`sem_unlink()`](http://www.opengroup.org/onlinepubs/000095399/functions/sem_unlink.html).
8c0cdf29 71* Clean our code to make it [style(9)](http://leaf.dragonflybsd.org/cgi/web-man?command#style&sectionANY) compatible. Compile and test your changes. Verify that the checksum (sha(1)) of the unmodified object matches the checksum of the cleaned object. Check also with strip(1)+sha(1)
8c0cdf29 72* Setup a regression testing machine/system to register and find problems and new improvements..
8c0cdf29 73* Networking performance scalability
193c08af 74 * scalability (algorithmic performance) - ideas: http://bulk.fefe.de/scalability/ and http://bulk.fefe.de/lk2006/talk.pdf
75 * RegressionTest
76 * also check HowToStressTest
8c0cdf29 77* fix `APIC_IO` on SMP
8c0cdf29 78* Port drivers from other systems. (Being able to support most of the wireless adapters out there would be nice.)
193c08af 79* Port TMPFS. Look [here](http://wiki.freebsd.org/TMPFS) for the work the FreeBSD guys did.
80* Port ZFS. Look [here](http://wiki.freebsd.org/ZFS) for the work the FreeBSD guys did.
8c0cdf29 81* Port NFSv4. [This mail](http://leaf.dragonflybsd.org/mailarchive/kernel/2008-01/msg00065.html) is a good starting point.
8c0cdf29 82* Port/sync the following from FreeBSD:
193c08af 83 * PCI code (to take advantage of power saving features)
84 * cpufreq and powerd
85 * netgraph modules. Contact joerg.
86 * Bring in support for UFS2, just the changes to extend the width of some fields from 32 bits to 64 bits.
87 * hardware drivers.
8c0cdf29 88* Port/sync the following from OpenBSD:
193c08af 89 * Add support for the NoExecute bit as described in [http://www.openbsd.org/papers/auug04/index.html](http://www.openbsd.org/papers/auug04/index.html).
90 * After that, make user stacks and data heaps non-executable. (W^X)
91 * hardware drivers, specially wireless.
92* Import/Update DRM from the DRM git repository ([http://dri.freedesktop.org/wiki/DRM](http://dri.freedesktop.org/wiki/DRM)).
8c0cdf29 93* CPU scheduler work:
0d29a1cd 94 * Design & implement a run-time switchable scheduler framework. (see Luigi's FreeBSD4 scheduler framework at [http://info.iet.unipi.it/~luigi/ps_sched.20020719a.diff](http://info.iet.unipi.it/~luigi/ps_sched.20020719a.diff) broken try [http://madchat.fr/tech/sched/FreeBSD/patch/ps_sched.20020719a.diff.txt](http://madchat.fr/tech/sched/FreeBSD/patch/ps_sched.20020719a.diff.txt))
193c08af 95 * The next step is to add a Solaris-like dispatcher framework that can handle more than one installed scheduling policy, all running on top of the base fixed lwkt priorities.
8c0cdf29 96* I/O scheduler work:
193c08af 97 * factor out, and make the IO scheduler plugabble.
98 * start with a "NOP" scheduler for RAM based devices
99 * implement a anticipatory scheduler (see documentation about the linux anticipatory scheduller)
100 * implement a Fair Queuing scheduler (even out the access to IO between competing processes/users)
8c0cdf29 101* Work relating LWKT (LightWeightKernelThreading)
193c08af 102 * Implement lazy IPI cross-processor lwkt message passing.
103 * Add timeout functionality to lwkt_waitmsg().
104 * Write man pages for the lwkt message passing API.
8c0cdf29 105* A real slab allocator. Contact corecode for patches.
8c0cdf29 106* clean up buildworld/kernel compilation warnings
8c0cdf29 107* Make the kernel more robust. Do this by removing any cases causing a kernel panic on memory allocation failure. Contact Devon H. O'Dell for information and ideas about how this might work.
8c0cdf29 108* Port XFS. (Contact joerg)
8c0cdf29 109* Computer Architecture related:
8c0cdf29 110* Port DragonFly over to Xen.
193c08af 111* Port DragonFly over to amd64 (look [here](http://cvsweb.dragonflybsd.org/cgi-bin/cvsweb.cgi/src/README.amd64) for more information).
8c0cdf29 112* Port DTrace
8c0cdf29 113* Capriccio threads
8c0cdf29 114* Xen support as domU and dom0 platform
8c0cdf29 115* DistributedFileSystem
