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.

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
|
2015-02-19 14:20:43 +03:00
|
|
|
+ do a type-punned pointer sweep for -fstrict-aliases (and fix the
|
|
|
|
|
problems, not the symptoms)
|
2003-09-02 16:01:14 +04:00
|
|
|
+ write a BSD-licensed web browser
|
2003-08-15 14:10:17 +04:00
|
|
|
+ perhaps look at putting wonka into src/ (with uuencoded class lib?)
|
|
|
|
|
+ write an overview document for openssl and certificates
|
|
|
|
|
+ documentation project help
|
2004-11-29 12:48:03 +03:00
|
|
|
+ Examine our vnode locking and vfs layer and see what needs to be changed
|
|
|
|
|
for locking in layered filesystems to really work
|
Apply the NFS exports list rototill patch:
- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
file sys/nfs/nfs_export.c. The former was becoming large and its code
is always compiled, regardless of the build options. Using the latter,
the code is only compiled in when NFSSERVER is enabled. While doing this,
also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
path and a set of export entries. At the moment it can only clear the
exports list or append entries, one by one, but it is done in a way that
allows setting the whole set of entries atomically in the future (see the
comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
that it becomes file system agnostic. In fact, all this whole thing was
done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
exports initialization; done internally by the kernel when initializing
the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
subsystems can run arbitrary code upon receipt of specific VFS events.
At the moment, this only provides support for unmount and is used to
destroy NFS exports lists from the file systems being unmounted, though it
has room for extension.

and advice in the development of this patch.

|
|
+ 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).
