| |
Hi,
It is not possible to build ipv6 for already compiled and running kernel, recompilation of whole kernel, even if building as a module, is typically a must. This is because ipv6-specific functions in drivers/char/random.c are inside #ifdefs, and as random.c is almost always built directly into kernel, recompilation of whole kernel can't be avoided. The corresponding functions for IPv4 in random.c are not inside those ifdefs, and I think that IPv6 shouldn't be either. Recompiling whole kernel just because I want to build ipv6 module is quite annoying. The following patch removes those ifdefs and makes additional compilation of ipv6 module possible.
