Catalin Marinas 69ebc01824 Revert "arm64: mm: add support for WXN memory translation attribute" ... This reverts commit 50e3ed0f93. The SCTLR_EL1.WXN control forces execute-never when a page has write permissions. While the idea of hardening such write/exec combinations is good, with permissions indirection enabled (FEAT_PIE) this control becomes RES0. FEAT_PIE introduces a slightly different form of WXN which only has an effect when the base permission is RWX and the write is toggled by the permission overlay (FEAT_POE, not yet supported by the arm64 kernel). Revert the patch for now. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Link: https://lore.kernel.org/r/ZfGESD3a91lxH367@arm.com		2024-03-13 10:53:20 +00:00
