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 39## Userland projects
b790f880 40
06d07101 41### One-liners
99e24f21 42 * Update the [[contributed software|docs/user/ContribSoftware]] which is out-of-date.
43 * Remove `NOINET6` build option
44 * `WARN` corrections to utilities
45 * Bring in code from other *BSDs:
46 * smbfs changes from FreeBSD
47 * pf changes from OpenBSD
48 * Add extended slice support to `fdisk`
49 * 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.
50 * C99 Standards Conformance. The todo list is on [[/docs/developer/StandardsConformanceProject]]
51 * Setup a regression testing machine/system to register and find problems and new improvements..
52 * Networking performance / scalability
53 * [[RegressionTest|/docs/developer/RegressionTest]]
54 * also check [[HowToStressTest|/docs/developer/HowToStressTest]]
55 * Add lwp support to ptrace/gdb/core dumps.
56 * [[/docs/developer/CheckpointFeatures]]
57 * Linuxulator update (FreeBSD did a lot of work in this area. Look [here](http://wiki.freebsd.org/linux-kernel),
58 * Bringing in version 2.0 of the BSD Installer
59 * UTF8 support in the console
06d07101 60
61### Scalability (algorithmic performance)
62 * [http://bulk.fefe.de/scalability/](http://bulk.fefe.de/scalability/)
63 * [http://bulk.fefe.de/lk2006/talk.pdf](http://bulk.fefe.de/lk2006/talk.pdf)
64
65### Write a tool to monitor changes in other code bases such as FreeBSD, NetBSD, OpenBSD.
66 * corecode is busy with this one (http://oly.corecode.ath.cx/~corecode/cgi-bin/crosscgi.py) (svn repository (https://fortunaty.net/svn/crossref/)).
67
68### Clean our code to make it [style(9)](http://leaf.dragonflybsd.org/cgi/web-man?command#style&sectionANY) compatible.
69 * Compile and test your changes.
70 * Verify that the checksum (sha(1)) of the unmodified object matches the checksum of the cleaned object. Check also with strip(1)+sha(1)
71
72### Port BSD-licensed tools (ex: `grep`, `diff` and `sort`)
73 * The OpenBSD guys already did some work related to that.
74 * If you manage to bring the tools to DragonFly, check if everything works as expected (e.g. rc.d scripts, make world runs, ...).
75 * The new tools need to have at least all the features of the old GNU tools.
76
77### Randomize mmap() offsets
78 * [http://www.openbsd.org/papers/ven05-deraadt/index.html](http://www.openbsd.org/papers/ven05-deraadt/index.html)
79
99e24f21 80### GDB
18741101 81 * ptrace/gdb follow-fork-mode support and more (peek at linux)
82 * Change the build to create one libbfd for gdb and binutils
83 * Separate RPC code from NFS into separate library.

85## Kernel projects
86
06d07101 87### One-liners
99e24f21 88 * Port the BSDL OSS code to DragonFly
89 * 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.
90 * 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.
91 * 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).
92 * 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)
93 * Setup a regression testing machine/system to register and find problems and new improvements..
94 * Networking performance scalability
95 * fix `APIC_IO` on SMP
96 * Port or update drivers from other systems.
97 * Port NFSv4. [This mail](http://leaf.dragonflybsd.org/mailarchive/kernel/2008-01/msg00065.html) is a good starting point.
98 * Import/Update DRM from the DRM git repository ([http://dri.freedesktop.org/wiki/DRM](http://dri.freedesktop.org/wiki/DRM)).
99 * clean up buildworld/kernel compilation warnings
100 * Port DragonFly over to Xen.
101 * Port DTrace
102 * Capriccio threads
103 * Xen support as domU and dom0 platform
06d07101 104
105### Code to port/sync from FreeBSD
193c08af 106 * PCI code (to take advantage of power saving features)
107 * cpufreq and powerd
108 * netgraph modules. Contact joerg.
109 * Bring in support for UFS2, just the changes to extend the width of some fields from 32 bits to 64 bits.
110 * hardware drivers.
99e24f21 111
06d07101 112### Code to port/sync from OpenBSD
193c08af 113 * 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).
114 * After that, make user stacks and data heaps non-executable. (W^X)
115 * hardware drivers, specially wireless.
06d07101 116
117### CPU scheduler:
118 * A scheduler API supporting multiple scheduler implementations already exists
119 * Add a Solaris-like dispatcher framework that can handle more than one installed scheduling policy
120
121### I/O scheduler
193c08af 122 * factor out, and make the IO scheduler plugabble.
123 * start with a "NOP" scheduler for RAM based devices
124 * implement a anticipatory scheduler (see documentation about the linux anticipatory scheduller)
125 * implement a Fair Queuing scheduler (even out the access to IO between competing processes/users)
06d07101 126
127### Work relating LWKT (LightWeightKernelThreading)
193c08af 128 * Implement lazy IPI cross-processor lwkt message passing.
129 * Add timeout functionality to lwkt_waitmsg().
130 * Write man pages for the lwkt message passing API.
