Hello,
There is currently a knob to enable/disable SSP: WITH_SSP or
WITHOUT_SSP. WITH_SSP is the default on -CURRENT, so no one had to put
WITH_SSP= in src.conf(5). This has hidden the following bug so far:
When buildworld is run with WITH_SSP= on command-line or in src.conf(5),
it fails immediately with the following message, because the toolchain
is built with WITHOUT_SSP:
% "/usr/src/share/mk/bsd.own.mk", line 365: WITH_SSP and WITHOUT_SSP can't both be set.
My leaning is to create an additional knob NO_SSP, much like
NO_CPU_CFLAGS, that could be set internally. However I'm not sure it
complies with the src.conf(5) policy. Any objection to the patch below?
Thank you!
Best regards,
--
