The effects were usually harmless, it would add bogus "binary" search directories to the places it actually looked for files.

| | | | | | | | | | | | | | | | | file is processed by passing its name in argv[1]: return(mod_loadobj(typestr, argv[1])); however, it is not tested to see if argv[1] actually is defined. At best, mod_loadobj() near line 244 returns an error like "can't find 'garbage'" but if the "filename" entered is sufficiently long, some buffer gets overrun. Of course, "load -t filename" is actually a typo because we meant to type "load -t mfs_root filename"; nevertheless, a hung machine seems like too harsh a punishment for such a small typo...

* The default search path for kernel and modules was bogus. It makes nodcs2000-09-161-1/+1
| | | | sense for /boot/kernel to come last.
* Fix autoboot. Now autoboot *always* show the correct kernel name. Itdcs2000-09-081-0/+1
| | | | | | | | | | | | | | | | | | gets the name from the environment variable kernelname, which is set when a kernel is loaded. For this reason, autoboot will _first_ try to load a kernel, and only proceed with the wait prompt after that succeeds. If it fails, it will abort immediately. While I understand some may think this behavior undesirable, I think it is, overall, the best thing to do, even if we do not consider the aesthetic issue. Notice that anyone using the default loader.rc already has the kernel loaded before autoboot. On unload, unset kernelname. Separate the code that tries to load a kernel from the list of options to the function loadakernel(). It is used by both boot() and autoboot().

* Fix a number of memory leaks and other memory-related disorders.dcs1999-03-081-4/+6
| | | | | | | | | | | | | | | Also, unbreak the breakage introduced at the last revision of module.c. This changes the semantics of mod_searchfile() (and mod_searchmodule()) to make the caller's responsibility freeing the buffer returned. This is different from other functions in loader's code, and was done as a fix for kern/9631. If someone wants to revert this to the original behavior, don't forget to fix kern/9631 in another way. This should also fix bin/10462, which was introduced as a result of the first try at kern/9631 (module.c last revision). PR: bin/10462 Submitted by: Takanori Saneto <sanewo@ba2.so-net.ne.jp>

* Resynch with working sources before BTX integration.msmith1998-09-141-30/+84
| | | | | | | | | | | - Use format-independant module allocator. - Conditionalise ISA PnP support. - Simplify PnP enumerator interface. - Improve module/object searching. - Add missing depend/install targets in BTX makefiles. - Pass the kernel environment and module data in extended bootinfo fields. - Add a pointer to the end of the kernel + modules in bootinfo. - Fix parsing of old-style kernel arguments.
* Bootstrap updates.msmith1998-09-031-38/+376
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move some startup code from MD to MI sections - Add a 'copyout' and some copyout-related functions. These will be obsoleted when BTX is available for the 386 and the kernel load area becomes directly addressable. - Add the ability load an arbitrary file as a module, associating and arbitrary type string with it. This can be used eg. for loading splash-screen images etc. - Add KLD module dependancy infrastructure. We know how to look for dependancies inside KLD modules, how to resolve these dependancies and what to do if things go wrong. Only works for a.out at the moment, due to lack of an MI ELF loader. Attach KLD module information to loaded modules as metadata, but don't pass it to the kernel (it can find it itself). - Load a.out KLD modules on a page boundary. Only pad the a.out BSS for the kernel, as it may want to throw symbols away. (We might want to do this for KLD modules too.) - Allow commands to be hidden from the '?' display, to avoid cluttering it with things like 'echo'. Add 'echo'. - Bring the 'prompt' command into line with the parser syntax. - Fix the verbose 'ls'; it was using an uninitialised stack variable. - Add a '-v' flag to 'lsmod' to have it display module metadata as well (not terribly useful for the average user) - Support a 'module searchpath' for required modules. - The bootstrap file on i386 is now called 'loader' to permit the /boot directory to use that name. - Discard the old i386 pread() function, as it's replaced by arch_readin()
* Bootloader update.msmith1998-08-311-3/+56
| | | | | | | | | | | | - Implement a new copyin/readin interface for loading modules. This allows the module loaders to become MI, reducing code duplication. - Simplify the search for an image activator for the loaded kernel. - Use the common module management code for all module metadata. - Add an 'unload' command that throws everything away. - Move the a.out module loader to MI code, add support for a.out kld modules. Submitted by: Alpha changes fixed by Doug Rabson <dfr@freebsd.org>
* This is the new unified bootstrap, sometimes known previously as themsmith1998-08-211-0/+129
'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.
