1# $NetBSD: TODO,v 1.19 2015/02/19 11:20:43 mrg Exp $ 2 3THINGS TO BE DONE: 4 5[ Note that this list does not include change requests filed via 'gnats'. 6 For information about them, mail query-pr@NetBSD.org. ] 7 8This is a list of things that need to be done for NetBSD. Some of 9these projects are small, others are large. Some are extremely 10important, others are enhancements to make the system more flexible 11for the wide variety of NetBSD users and their applications. 12 13In general there are some guidelines for work to be included in 14NetBSD. Chief among these are: 15 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 21 directories 22 23Associated with some entries are login names which indicate persons or 24groups who may already be working on that problem. This isn't to say 25that others shouldn't also look at it, but consultation with other 26parties may result in less duplicated work. A directory of these 27persons can be found after the todo list itself. 28 29Please don't hesitate to suggest more projects for this list. 30Suggestions, comments, etc to projects@NetBSD.org. 31 32High Kernel: 33 swap fixes: 34 swap to file of dynamic size; see apollo 35 36User programs: 37 rwall nfs-mountees on shutdown 38 39i386 kernel support: 40 make use of sysenter/sysexit instructions on PIII/4 and Athlon for 41 reducing syscall overhead. 42 43This is a list of suggested smaller projects (in no particular order): 44 45+ speed up sort(1) by using mmap(2) rather than temp files 46+ port valgrind to NetBSD for pkgsrc, then use it to do an audit of 47 any memory leakage 48+ simplify some of the quirks in our build system 49+ investigate zebra or quagga in gnusrc rather than routed 50+ do a type-punned pointer sweep for -fstrict-aliases (and fix the 51 problems, not the symptoms) 52+ write a BSD-licensed web browser 53+ perhaps look at putting wonka into src/ (with uuencoded class lib?) 54+ write an overview document for openssl and certificates 55+ documentation project help 56+ Examine our vnode locking and vfs layer and see what needs to be changed 57 for locking in layered filesystems to really work 58+ Make mountd(8) update the in-kernel exports list for each file system 59 atomically. Many parts of the utility will need a rewrite, but the kernel 60 functionality is already there (just enable the "notyet" blocks of code in 61 sys/nfs/nfs_export.c). 62
