THINGS TO BE DONE:

[ Note that this list does not include change requests filed via 'gnats'.

For information about them, mail [email protected]. ]

This is a list of things that need to be done for NetBSD. Some of

these projects are small, others are large. Some are extremely

important, others are enhancements to make the system more flexible

for the wide variety of NetBSD users and their applications.

In general there are some guidelines for work to be included in

NetBSD. Chief among these are:

(1) Keep GPLed stuff out of the kernel.

(2) Introduce little to no more GPLed stuff as non-optional

components of the user environment.

(3) Only clean code, that lends itself to further enhancement

(4) Keep architecture dependent code out of architecture independent

directories

Associated with some entries are login names which indicate persons or

groups who may already be working on that problem. This isn't to say

that others shouldn't also look at it, but consultation with other

parties may result in less duplicated work. A directory of these

persons can be found after the todo list itself.

Please don't hesitate to suggest more projects for this list.

High Kernel:

swap fixes:

swap to file of dynamic size; see apollo

User programs:

rwall nfs-mountees on shutdown

This is a list of suggested smaller projects (in no particular order):

+ speed up sort(1) by using mmap(2) rather than temp files

+ port valgrind to NetBSD for pkgsrc, then use it to do an audit of

any memory leakage

+ simplify some of the quirks in our build system

+ investigate zebra or quagga in gnusrc rather than routed

+ do a type-punned pointer sweep for -fstrict-aliases (and fix the

problems, not the symptoms)

+ perhaps look at putting wonka into src/ (with uuencoded class lib?)

+ write an overview document for openssl and certificates

+ documentation project help

+ Examine our vnode locking and vfs layer and see what needs to be changed

for locking in layered filesystems to really work

+ Make mountd(8) update the in-kernel exports list for each file system

atomically. Many parts of the utility will need a rewrite, but the kernel

functionality is already there (just enable the "notyet" blocks of code in

sys/nfs/nfs_export.c).
