- It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.

# All library objects contain FreeBSD revision strings by default; they may be
|
|
# excluded as a space-saving measure. To produce a library that does
|
|
# not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
|
|
# below. Note, there are no IDs for syscall stubs whose sources are generated.
|
|
# To included legacy CSRG sccsid strings, add -DLIBC_SCCS and -DSYSLIBC_SCCS
|
|
# (for system call stubs) to CFLAGS below. -DSYSLIBC_SCCS affects just the
|
|
# system call stubs.
