From 2bdc74f3d7c4cacb65dbde910471c62992640275 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Mon, 1 Feb 2021 23:05:51 +0100 Subject: [PATCH] linux-user: fix O_NONBLOCK usage for hppa target Historically the parisc linux port tried to be compatible with HP-UX userspace and as such defined the O_NONBLOCK constant to 0200004 to emulate separate NDELAY & NONBLOCK values. Since parisc was the only Linux platform which had two bits set, this produced various userspace issues. Finally it was decided to drop the (never completed) HP-UX compatibilty, which is why O_NONBLOCK was changed upstream to only have one bit set in future with this commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=75ae04206a4d0e4f541c1d692b7febd1c0fdb814 This patch simply adjusts the value for qemu-user too.
