Message-ID: <55CA90B4.2010205@list.ru> Date: Wed, 12 Aug 2015 03:17:56 +0300 From: Stas Sergeev <stsp@...t.ru> To: Andy Lutomirski <luto@...capital.net> Cc: Linux kernel <linux-kernel@...r.kernel.org> Subject: [regression] x86/signal/64: Fix SS handling for signals delivered to 64-bit programs breaks dosemu Hi guys, I wonder how easily the include/uapi/* is being changed these days. The patch: http://lkml.kernel.org/r/405594361340a2ec32f8e2b115c142df0e180d8e.1426193719.git.luto@kernel.org breaks dosemu (and perhaps everyone else who used to restore the segregs by hands). And the fix involves both autoconf magic and run-time magic, so it is not even trivial. I realize this patch may be good to have in general, but breaking userspace without a single warning is a bit discouraging. Seems like the old "we don't break userspace" rule have gone. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
