This needs to be resolved - by fixing the header files, which I haven't bothered to do (the - main conflict was "printf", and I made a dirty hack to get - around it until the header files have been fixed). - - -3.0 Usage warnings - - Loading a bogus module will kill your machine, but if you are - doing development, this will end up happening (hopefully) - less frequently than changing, recompiling, installing, and - rebooting would normally occur. This should speed development - considerably for a lot of the in-kernel work that is currently - taking place. - - -4.0 Loadable module types supported - - There are six loadable modules types supported; five of these are - specific module types; the sixth is to allow the user to make - their own loader as part of the module and allow them to replace - or extend appropriate tables in the kernel. - - -4.1 System call modules - - System calls as loadable modules use one of two approaches. - - If the system call slot is unspecified (-1), it will attempt - to locate (and allocate) the next free call slot that points - to the address of the "lkmnosys" function (an alias for the - "nosys" function). It replaces this with the user's call; - the user can tell which slot was allocated using the "modstat" - command (the call slot is indicated by the value of "Off"). - - If the system call slot is specified, it will replace that - specific call (assuming it is in range of the entries in the - sysent[] table). Care should be taken when replacing system - calls. Good candidates are calls that the user is attempting - to repair or make POSIX compliant. It is possible to replace - all calls, although care should be taken with the "ioctl()" - call, as it is the interface for the lkm loader. - - When unloaded, the system call module replaces the previous - contents of the call slot. If this was an allocable slot, it - is now reallocable; if it was a particular call slot, the - previous function is restored. - - The directory ./sample/syscall contains a sample implementation - of a loadable system call. - - -4.2 Virtual file system modules - - A virtual file system can be loaded as a module. The example - provided is for the "kernfs" file system; this is the code in - NetBSD's /sys/kernfs combined in a single object with another - piece of code giving a module entry point for the file system; - with very little effort, any file system can be set up this way - (although I suggest you leave "ufs" statically linked, since - it is necessary for booting). - - The critical section of loading a VFS is to get the entry in - the right slot and mounted. - - Because of the dependency on the vfssw[] table index during - the mount, we can't simply mix and match file systems except - in their predefined locations with regard to mount. This - means that there are changes to vfssw[] and mount coming - down the road (which will end up incrementing the lkm version - and introducing an incompatibility as far as file system modules - are concerned). - - The directory ./sample/vfs contains the sample implementation - of the loadable kernfs vfs. - - -4.3 Device driver modules - - The major issue to deal with when creating device drivers is - ensuring the creation of the device node. The current approach - to this is executing a module specific shell script upon a - successful load. - - A potentially better solution is encoding the device name in - the device switch, or, better, providing a functional interface - to the init routine, and then using a "/devices" file system - to export devices to the file system name space. Of course, - the default "/dev" directory would have to be maintained for - compatibility (probably using symbolic links). - - This distribution does not contain a loadable device driver - example. A potentially beneficial example could be made of - the "lpa" interruptless printer driver. - - -4.4 Streams modules - - Streams module support has been removed from this release; when - the streams implementation is ready, it will be restored as a - patch. - - Please do not ask me for early availability on my streams - implementation; until I have some non-proprietary modules - to distribute, I'm putting work on it on the back burner - while I finish shared libraries. - - -4.5 Execution interpreters - - Execution interpreters allow loading of programs with magic - numbers other than the default numbers supported by NetBSD. - This allows user space development of changes in exec format - to support, among other things, shared libraries. - - Another potential use requires changing the references to - the "sysent[]" system call table from direct references to - indirect through a pointer in the proc struct. This allows - the execution interpreter to, among other things, support - (statically linked) executables from other environments, - like XENIX, SVR3, SVR4, and Linux. - - There is no example of a loadable execution interpreter - provided with this distribution. - - -4.6 Miscellaneous modules - - Miscellaneous modules are modules for which there is not a - current, well-defined, or well-used interface for extension. - They are provided for extension, and the user is expected to - write their own loader to handle the kernel pointer/table - manipulation to "wire in" their loaded module (and "unwire" - it on unload). - - One example of a "miscellaneous module" might be a loader for - card-specific VGA drivers or alternate terminal emulations in - an appropriately layered console driver. - - The table manipulations required are specific to the console - interface, yet a loadable module may be used if code is written - to tell it how to manipulate the interfaces within the internal - console interfaces. - - An example of a "miscellaneous module" is provided to show how - to write "miscellaneous modules"; it duplicates the functionality - of the "system call" module type, and is not intended to be - seriously used, as it could interfere with the "system call" - module type. The sample code is located in ./sample/misc. - - - -5.0 END OF DOCUMENT diff --git a/share/lkm/misc/Makefile b/share/lkm/misc/Makefile deleted file mode 100644 index af1f7969cfb..00000000000 --- a/share/lkm/misc/Makefile +++ /dev/null @@ -1,49 +0,0 @@ -# $OpenBSD: Makefile,v 1.2 2000/03/02 14:46:36 todd Exp $ -# -# Makefile for sample loadable system call -# -# 25 May 93 Terry Lambert Original -# -# Copyright (c) 1993 Terrence R.

To unload it, - type the following from the directory this file is in: - - cd module - make unload - - The miscellaneous module will be unloaded by name. - - -4.0 END OF DOCUMENT diff --git a/share/lkm/misc/module/Makefile b/share/lkm/misc/module/Makefile deleted file mode 100644 index 978f9d49c61..00000000000 --- a/share/lkm/misc/module/Makefile +++ /dev/null @@ -1,66 +0,0 @@ -# $OpenBSD: Makefile,v 1.3 2000/03/02 14:46:36 todd Exp $ -# -# Makefile for miscmod -# -# 05 Jun 93 Terry Lambert Original -# -# Copyright (c) 1993 Terrence R.
