iproute2 contains a bunch of kernel headers, including uapi ones. Android's libc uses uapi headers almost directly, and uses a script to fix kernel types that don't match what userspace expects. For example: https://issuetracker.google.com/36987220 reports that our struct ip_mreq_source contains "__be32 imr_multiaddr" rather than "struct in_addr imr_multiaddr". The script addresses this by replacing the uapi struct definition with a #include <bits/ip_mreq.h> which contains the traditional userspace definition. Unfortunately, when we compile iproute2, this definition conflicts with the one in iproute2's linux/in.h. Historically we've just solved this problem by running "git rm" on all the iproute2 include/linux headers that break Android's libc. However, deleting the files in this way makes it harder to keep up with upstream, because every upstream change to an include file causes a merge conflict with the delete. This patch fixes the problem by moving the iproute2 linux headers from include/linux to include/uapi/linux. Tested: compiles on ubuntu trusty (glibc) Signed-off-by: Elliott Hughes <enh@google.com> Signed-off-by: Lorenzo Colitti <lorenzo@google.com>
