From 7815c55f7d0ee4bef94ddc54c4845c399f964719 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 22 Apr 2023 19:48:54 +0200 Subject: [PATCH] kernel: Deactivate CONFIG_COMPAT This deactivates the CONFIG_COMPAT kernel option. With CONFIG_COMPAT the kernel will provide syscall interfaces for arm32 binaries in addition to the interfaces needed for arm64 binaries. In OpenWrt the complete userspace is compiled for this specific architecture and support for 32 bit ARM applications is not needed. This reduces the size and the attack surface for the systems. On all other targets CONFIG_COMPAT is already deactivated.
