Compile error with 2.1.7-2.6.14.3-200511261227

Same config with 2.6.13-2 worked fine.

Can you mail me your complete config? I'm unable to reproduce this problem.

-Brad

[linuxuser]

Sent the full config to your e-mail. Thanks for looking into this. It may simply be that I'm doing something unusual in my config, in which case, I can probably change it.

[spender]

I just successfully compiled a kernel with your configuration. Can you check to make sure your kernel source and patch haven't been corrupted?

-Brad

[linuxuser]

The archives look good. Perhaps this a problem with older redhat distributions? I'm building this on a rh9 box.

Gonna try cleaning up the build environment, maybe there is some cruff laying around that is throwing off the build.

[linuxuser]

The problem only seems to be with the paging based non-executable PAX option, when compiled on a rh9 box with gcc 3.2.2. All the other PAX options compile, and with the 2.6.13 patch, they compiled as well.

My best guess is that the gcc 3.2.2 compiler doesn't like something with the new patch. Maybe something as subtle as a syntax issue with newer compilers that the older 3.2.2 compiler doesn't like. I'll see if I can find out what exactly is causing it.

[linuxuser]

For some reason, gcc 3.2.2 doesn't like this:

Starting on line 354 of arch/i386/mm/fault.c:

#ifdef CONFIG_SMP
&& cpu_isset(smp_processor_id(), mm->context.cpu_user_cs_mask)
#endif

It looks like gvv 3.2.2 doesn't like the format. Without it, its compiling just fine, well, with one minor warning:

arch/i386/mm/fault.c: In function `do_page_fault':
arch/i386/mm/fault.c:627: warning: unused variable `pte'

This box isn't SMP, so I'm not concerned about pull this out. So I think this is just a gcc syntax issue.

[PaX Team]

So I think this is just a gcc syntax issue.

indeed, it's a nesting of ifdef inside define, to fix it, change that whole construct to:

Code: Select all

#ifdef CONFIG_SMP
        if (likely(address > get_limit(regs->xcs) && cpu_isset(smp_processor_id(), mm->context.cpu_user_cs_mask)))
#else
        if (likely(address > get_limit(regs->xcs)))
#endif


[spender]

It's fixed in the latest patch on the website. I didn't catch it earlier because my gcc was accepting it as valid.

i have the same problem with kernel 2.6.18
