+@node Stack Smashing Protection
+@section Stack Smashing Protection
+Stack Smashing Protection is a compiler feature which emits extra code
+to check for stack smashing attacks. It depends on a canary, which is
+initialized with the process, and functions for process termination when
+an overflow is detected. These are private entry points intended solely
+for use by the compiler, and are used when any of the @code{-fstack-protector},
+@code{-fstack-protector-all}, @code{-fstack-protector-explicit}, or
+@code{-fstack-protector-strong} compiler flags are enabled.
+
+@node Object Size Checking
+@section Object Size Checking
+Object Size Checking is a feature which wraps certain functions with checks
+to prevent buffer overflows. These are enabled when compiling with
+optimization (@code{-O1} and higher) and @code{_FORTIFY_SOURCE} defined
+to 1, or for stricter checks, to 2.
+
+@cindex list of overflow protected functions
+The following functions use object size checking to detect buffer overflows
+when enabled:
+
+@example
+@exdent @emph{String functions:}
+bcopy memmove strcpy
+bzero mempcpy strcat
+explicit_bzero memset strncat
+memcpy stpcpy strncpy
+
+@exdent @emph{Stdio functions:}
+fgets fread_unlocked sprintf
+fgets_unlocked gets vsnprintf
+fread snprintf vsprintf
+
+@exdent @emph{System functions:}
+getcwd read readlink
