From 0444a3b7935f6e09dfddf00411840e70f6fd933e Mon Sep 17 00:00:00 2001 From: Aleksandar Markovic Date: Mon, 19 Sep 2016 13:44:43 +0200 Subject: [PATCH] linux-user: Add missing TARGET_EDQUOT error code for Mips EDQUOT is defined for Mips platform in Linux kernel in such a way that it has different value than on most other platforms. However, correspondent TARGET_EDQUOT for Mips is missing in Qemu code. Moreover, TARGET_EDQUOT is missing from the table for conversion of error codes from host to target. This patch fixes these problems. Without this patch, syscalls add_key(), keyctl(), link(), mkdir(), mknod(), open(), rename(), request_key(), setxattr(), symlink(), and write() will not be able to return the right error code in some scenarios on Mips platform. (Some of these syscalls are not yet supported in Qemu, but once they are supported, they will need correct EDQUOT handling.)
