Cover a potential buffer overrun problem

1996-08-13T00:43:01Z

changed a strchr to a strrchr so that modules with a `.' in the path

can be loaded (e.g. ./mymod.o)

Add a few more heuristics to modload:

1: generate the outfile in /tmp if it's not specified explicitly. 2: if the outfile was implicitly placed in /tmp, automatically remove it. This means that you can type: modload /lkm/ipfw_mod.o and it'll work, it wont try and write to /lkm, and it wont leave the (normally) useless symbol file. This should not interfere with things like ibcs2 and atapi, which export some symbols from one LKM to the other by leaving the symbol file.

Make modload calculate a reasonable default entry point name, in light

of the recent changes to bsd.kmod.mk, which enforces that the entry point be _mod, unless overridden. This means that when modloading "/lkm/foo_mod.o", it'll use "foo_mod" as the default entry point (instead of xxxinit) unless you specify another via the -e option.
