disable aio support in recommended configuration

2017-05-28T16:04:04+00:00

The aio interface adds substantial attack surface for a feature that's not being exposed by Android at all. It's unlikely that anyone is using the kernel feature directly either. This feature is rarely used even on servers. The glibc POSIX aio calls really use thread pools. The lack of widespread usage also means this is relatively poorly audited/tested. The kernel's aio rarely provides performance benefits over using a thread pool and is quite incomplete in terms of system call coverage along with having edge cases where blocking can occur. Part of the performance issue is the fact that it only supports direct io, not buffered io. The existing API is considered fundamentally flawed and it's unlikely it will be expanded, but rather replaced: https://marc.info/?l=linux-aio&m=145255815216051&w=2 Since ext4 encryption means no direct io support, kernel aio isn't even going to work properly on Android devices using file-based encryption.

ANDROID: base-cfg: enable CONFIG_IP_NF_NAT

2017-04-13T10:35:12+00:00

IP_NF_TARGET_{MASQUERADE,NETMAP,REDIRECT} configs, already enabled in android-base.cfg for tethering, are of no use if CONFIG_IP_NF_NAT is not enabled. Don't rely on platform config for that and enable CONFIG_IP_NF_NAT in android-base.cfg as well.
