[1] glibc-2.3.4 kill buggy bins at the load time.
(please look into: elf/dl-load.c, elf/dl-support.c, elf/rtld.c)
This works on i386/PaX systems too (hardware NX isn't required).
[2] `readelf -Wl |grep GNU_STACK` shows RWE ;-)
Please look at this quick example.
# gcc tmp1.c tmp2-invalid.S -o tmp -s
# readelf -Wl tmp
(...)
GNU_STACK 0x00 0x 0x 0x0 0x0 RWE 0x4
^ execstack?
PAX_FLAGS 0x00 0x 0x 0x0 0x0 0x4
(...)
Now, let's add section note to the asm. file and rebuild.
# gcc tmp1.c tmp2-valid.S -o tmp -s
# readelf -Wl tmp
(...)
GNU_STACK 0x00 0x 0x 0x0 0x0 RW 0x4
PAX_FLAGS 0x00 0x 0x 0x0 0x0 0x4
(...)
The execstack req. disappeard (~99% of broken sources).
I get the same effect with fixed cflags and invalid source.
# gcc tmp1.c tmp2-invalid.S -o tmp -s -Wa,--noexecstack
# readelf -Wl tmp
(...)
GNU_STACK 0x00 0x 0x 0x0 0x0 RW 0x4
PAX_FLAGS 0x00 0x 0x 0x0 0x0 0x4
(...)
I known several apps that really need executable data/stack (eg. jvm, xorg).
The rest of RWE-marked binaries have IMHO buggy sources.
> It would be fine if there was a compile time error or something,

IMHO the `as` should warn about missed (.note.GNU-stack) section.

PaweÅ.

Re: [PROPOSAL/PATCH] Remove PT_GNU_STACK support before 2.6.11
My proposal is to recompile broken software with cflags += -Wa,--noexecstack. This works fine with e.g. 2.6.10+pax/i386. -- /* Copyright (C) 2003, SCO, Inc.
