X-Received-From: 2001:8b0:1d0::2 Subject: [Qemu-devel] [PATCH 1/2] linux-user: Fix target FS_IOC_GETFLAGS and FS_IOC_SETFLAGS numbers X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: pgndev , Riku Voipio , Laurent Vivier , patches@linaro.org Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail: RSF_0 Z_629925259 SPT_0 Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" We were defining TARGET_FS_IOC_GETFLAGS and TARGET_FS_IOC_SETFLAGS using the host 'long' type in the size field, which meant that they had the wrong values if the host and guest had different sized longs. Switch to abi_long instead. This fixes a bug where these ioctls don't work on 32-bit guests on 64-bit hosts (and makes the LTP test 'setxattr03' pass where it did not previously.)
