[meta-intel] [met-intel-quark] Enable stack-protector defense support for SPI image

[Ramajayam, Yugeraj]

Hi Brian, 

I followed as you said. I ran, 

1. $ bitbake -c menuconfig uclibc
2. Selected fstack-protector option 
3. Copied the .config file from build/tmp-spi/work/i586-poky-linux-uclibc/uclibc/0.9.33+gitAUTOINC+48a0006012-r9/git/.config
4. I replaced ../meta/recipes-core/uclibc/uclibc-git/uClibc.distro with .config and renamed it as uClibc.distro and did a $ bitbake uclibc
5. After compilation, I checked the build/tmp-spi/work/i586-poky-linux-uclibc/uclibc/0.9.33+gitAUTOINC+48a0006012-r9. The Uclibc.distro there is the same as I changed in ../meta/recipes-core/uclibc/uclibc-git/uClibc.distro with all the SSP (stack-protector) related configs built in.
6. But, when I checked .config file at  build/tmp-spi/work/i586-poky-linux-uclibc/uclibc/0.9.33+gitAUTOINC+48a0006012-r9/git/.config, the SSP configs are disabled as in my previous build. Somehow the stack-protector features were not passed over to the final .config

Is there any other way for me to check if those stack-protector options are enabled ?
Or did I missing some steps ??

Regards,
RAJ

I had a quick go with meta-intel-quark and it worked as expected, I modified the config by using:

$ bitbake -c menuconfig uclibc

Grabed the config file from
build/tmp-spi/work/i586-poky-linux-uclibc/uclibc/0.9.33+gitAUTOINC+48a0006012-r9/git/.config
and then rebuilt uclibc with that config file. My guess is that you manually modified the config file instead of using menuconfig so it reverted you to the default as there where conflicting options?

Cheers,
Brendan
