From 6ea7bb00c1ba180f8bf8320b8d59b532501c5271 Mon Sep 17 00:00:00 2001 From: Rick Edgecombe Date: Fri, 1 Sep 2023 11:16:52 -0700 Subject: [PATCH] selftests/x86: Update map_shadow_stack syscall nr Shadow stack's selftest utilizes the map_shadow_stack syscall. The syscall is new with the feature, but the selftests cannot automatically find the headers for the kernel source tree they are located in. This resulted in the shadow stack test failing to build until the brand new headers were installed. To avoid this, a copy of the new uapi defines needed by the test were included in the selftest (see link for discussion). When shadow stack was merged the syscall number was changed, but the copy in the selftest was not updated. So update the copy of the syscall number define used when the required headers are not installed, to have the final syscall number from the merge.
