Re: [PATCH] PT_GNU_STACK

Hi Andrew,


Wouldn't two note sections work better:

	if (.note.GNU-stack.rwx)
	  stack read-write-executable
	else if (.note.GNU-stack.rw)
	  stack read-write

Having empty sections would let binutils ignore the problem entirely. Instead it could just pass the sections through.

	else
	  stack $KERNEL_CONFIG_VARIABLE

gcc generating one or the other (all empty). 


What benefit does this have over having just one note section and
checking the section's attributes ?

The other advantage is that BINUTILS would not have the policy / contents of the .note section hard wired. Such defaults should be comming from something outside of BINUTILS (eg crt0.o, crt0begin.o, kernel option, et.al.). Not matter how much people tell you otherwize, you can bet on there being a request to change the default - arrrrggghghg!

You could have code merging existing note sections (although that really strikes me as weird) (and something that will slow down the link??).

Andrew
