.SH ENVIRONMENT
+Various environment variable influence the operation of the dynamic linker.
+.\"
+.SS Secure-execution mode
+For security reasons,
+the effects of some environment variables are voided or modified if
+the dynamic linker determines that the binary should be
+run in secure-execution mode.
+This determination is made by checking whether the
+.B AT_SECURE
+entry in the auxiliary vector (see
+.BR getauxval (3))
+has a nonzero value.
+This entry may have a nonzero value for various reasons, including:
+.IP * 3
+The process's real and effective user IDs differ,
+or the real and effective group IDs differ.
+This typically occurs as a result of executing
+a set-user-ID or set-group-ID program.
+.IP *
+A process with a non-root user ID executed a binary that
+conferred permitted or effective capabilities.
+.IP *
+A nonzero value may have been set by a Linux Security Module.
