On: Google's Android faces a serious Linux copyright issue

[FlorianMueller]

Linus Torvalds says that "normal system calls" are allowed, but once you use the original kernel headers, you're subject to the GPL: http://lkml.org/lkml/2003/12/5/13 The way to avoid this is to use glibc.

In relation to Android and Bionic, I think the following message from the same thread is more relevant:

http://lkml.org/lkml/2003/12/5/162

(in general, the thread was about kernel modules - this message explicitly mentions user-space)
