From b1755cea5d8116eb8f3b0cf4c12359b9b2052bb4 Mon Sep 17 00:00:00 2001 From: Justine Tunney Date: Tue, 16 Jun 2020 06:41:10 -0700 Subject: [PATCH] Darth Raadt is holding the Bell Labs ABI hostage The binary system interfaces designed at Bell Labs were what helped our friends like Linus Torvalds become successful. It's why Torvalds always respected syscall abi and made every effort to not break the userspace. Sadly OpenBSD developer Theo de Raadt thinks respecting Bell interfaces is a risk for security and conjured up the Return Oriented Programming bogeyman to justify his policies, per https://lwn.net/Articles/806776/ See libc/nexgen32e/gc.S where we use ROP concepts for garbage collection in C due to our belief that powerful programming techniques can be good. See https://opensource.googleblog.com/2017/03/operation-rosehub.html for an example of something similar to rop but potentially more of a concern --- libc/dce.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libc/dce.h b/libc/dce.h index 7889ccab..55747393 100644 --- a/libc/dce.h +++ b/libc/dce.h @@ -24,7 +24,7 @@ #define METAL 2 #define WINDOWS 4 #define XNU 8 -#define OPENBSD 16 +#define OPENBSD 16 /* 2019-12-11: new openbsd drm might thwart syscall */ #define FREEBSD 32 /* #define YOUR_CLOUD_PLATFORM_HERE 64 /\* jtunney@gmail.com *\/ */ /* #define YOUR_CLOUD_PLATFORM_HERE 128 /\* jtunney@gmail.com *\/ */
