Hi Eric, > The general case requires self modifying code. Where do you need this in the > kernel. For most callbacks the kernel is already passing a fairly generic > parameter you can use. So this trick should be unnecessary. In my case the problem is indeed fairly general, so I can't seem to count on a generic parameter. Most callbacks do have them, but not all of them. Anyway, since you agree the general case requires self modifying code I'll do it that way. Now I just need to know how to make a page executable in a portable way (get_free_page on i386 already returns executable pages...) If anyone's interested in the background of this: I'm writing a kernel module containing an interpreter for the Python language, which in turn accesses the kernel functions through a wrapper layer. This makes writing kernel modules in pure Python possible. I know this is rather sick :) cheers Matthias - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
