8 This is a list of things that need to be done for NetBSD. Some of
9 these projects are small, others are large. Some are extremely
10 important, others are enhancements to make the system more flexible
11 for the wide variety of NetBSD users and their applications.
13 In general there are some guidelines for work to be included in
14 NetBSD. Chief among these are:
16 (1) Keep GPLed stuff out of the kernel.
17 (2) Introduce little to no more GPLed stuff as non-optional
18 components of the user environment.
19 (3) Only clean code, that lends itself to further enhancement
20 (4) Keep architecture dependent code out of architecture independent
23 Associated with some entries are login names which indicate persons or
24 groups who may already be working on that problem. This isn't to say
25 that others shouldn't also look at it, but consultation with other
26 parties may result in less duplicated work. A directory of these
27 persons can be found after the todo list itself.
29 Please don't hesitate to suggest more projects for this list.
30 Suggestions, comments, etc to projects@NetBSD.org.
34 swap to file of dynamic size; see apollo
36 kernel support for lockd(8), lockf(3)
39 rwall nfs-mountees on shutdown
40 add detachment to window(1)
41 clean up gas config files, set up common defines
44 someone should actually test all the netiso stuff.
47 modify sys docs to reflect NetBSD/arch-specific stuff
48 clean up src/share/man/{man0,tools} so that we can generate a printable
49 version from the manpages again.
52 better ways of accessing BIOS, i/o space. some exportable to
53 user space. See mach3,linux dos emulator
54 i686 optimized versions of copyin/copyout/memcpy/memset/etc. lazy
55 floating-point context switching should be implemented as well.
56 make use of sysenter/sysexit instructions on PIII/4 and Athlon for
57 reducing syscall overhead.
59 This is a list of suggested smaller projects (in no particular order):
61 + speed up sort(1) by using mmap(2) rather than temp files
62 + autoconf version of nawk, for use in non-NetBSD pkgsrc
63 + port valgrind to NetBSD for pkgsrc, then use it to do an audit of
65 + implement POSIX async IO
66 + help in implementing various things in pkgsrc
67 + simplify some of the quirks in our build system
68 + help out with scripts for tgm/autobuild
69 + some PR fixing/re-categorising/investigating/closing
70 + investigate zebra or quagga in gnusrc rather than routed
71 + do a type-punned pointer sweep for gcc3 (and fix the problems, not
73 + kernel fine-grained locking
74 + write a BSD-licensed web browser
75 + write a BSD-licensed privacy guard like gnupg or pgp
76 (see http://netbsd-soc.sourceforge.net/projects/bpg/)
77 + perhaps look at putting wonka into src/ (with uuencoded class lib?)
78 + investigate ProPolice
79 + document autoconf framework
80 + write an overview document for openssl and certificates
81 + documentation project help
82 + investigate which userland utilities and daemons would benefit from
83 kqueue, and rewrite them
84 + better testing in general; in particular, more regression tests
85 + add a native scheme interpreter
86 + add platform support for TenDRA compiler suite
87 + merge moused(8) with wsmoused(8) as a new work mode (i.e. serial)
88 + re-design our mbuf/network buffer memory handling so that it is simpler
89 and can handle zero copy tcp
90 + re-design our signal handling path. It is far too complicated and will not
91 be easy to accommodate MP code
92 + Examine our vnode locking and vfs layer and see what needs to be changed
93 for locking in layered filesystems to really work
94 + Make mountd(8) update the in-kernel exports list for each file system
95 atomically. Many parts of the utility will need a rewrite, but the kernel
96 functionality is already there (just enable the "notyet" blocks of code in
97 sys/nfs/nfs_export.c).
98 + Kerberize more services like ftp, ftpd, rsh, rshd, rlogind, ...
