Bug#728975: linux: [ARM] CONFIG_OABI_COMPAT harmful (slower, unsafe, breaks at least seccomp and audit)
Package: linux
Severity: normal
Tags: security

The issue is not yet closed in LKML, but basically OABI_COMPAT enabled seems
to be a danger: at least seccomp and audit should not be used with OABI, and
to top it off it is not "free" as far as performance goes, either: a fair
amount of added complexity, and an extra D-cache miss on every syscall.
