Could we harden GCC's stack smashing? (Re: Adam Zabrocki's Adventure with stack smashing protection)

Hello, Adam Zabrocki's Adventure with stack smashing protection at (http://blog.pi3.com.pl/?p=485 ) is kind of interesting. It lists some possible weaknesses in GCC's -fstack-protector. Given that the weaknesses happen when the stack has already been smashed I do not think they are critical but th

Hi, So far I've been testing with hardware but I'm pretty sure I read somewhere about an RL78 simulator, which would be a useful addition. Does this simulator exist, and if so, how do I run the tests against it? I tried 'make -k check RUNTESTFLAGS="--target_board=rl78-sim"' but in amongst th

Thank you, I must then apologize to the GCC mailing list for bringing up something off topic. About GCC's _stack_chk_fail. Yeah, it's much simpler. Personally, I wouldn't trust syslog but I'm not sure of a good alternative. I'll go bother the GLibc people. Thank you, Steven Stewart-Gallus P.S. I
