From f7e97cea20f3ca0966c6b505da953827d2b0891c Mon Sep 17 00:00:00 2001 From: Sam James Date: Sat, 5 Aug 2023 00:04:33 +0100 Subject: sysdeps: tst-bz21269: handle ENOSYS & skip appropriately SYS_modify_ldt requires CONFIG_MODIFY_LDT_SYSCALL to be set in the kernel, which some distributions may disable for hardening. Check if that's the case (unset) and mark the test as UNSUPPORTED if so.
