Subject: Re: [PATCH v2] kmod: Handle undefined O_CLOEXEC
Date: Tue, 24 Jul 2012 10:37:41 +0300	[thread overview]
Message-ID: <500E50C5.8000403@intel.com> (raw)
In-Reply-To: <lywr1uzguj.fsf@ensc-virt.intern.sigma-chemnitz.de>

As far as kmod package is concerned O_CLOEXEC is used in constructs like 
"O_RDONLY|O_CLOEXEC". O_CLOEXEC can be used (is defined) starting with 
Linux kernel ≥2.6.23 and glibc ≥2.7 case in which the patch does not 
logically changing anything. However, prior Linux kernel ≥2.6.23 
O_CLOEXEC is not defined (the case for CentOS 5.8 - kernel 2.6.18) and 
using it in code will cause build errors. My patch provides a workaround 
for those distributions that do not have O_CLOEXEC define, just to be 
able to build stuff. I have not tested on CentOS 5.8 if the applications 
are not broken in some way, but that's not in the scope of this patch. 
If something does indeed break, then a totally different patch is 
required, targeting a backport of kmod for kernel older than 2.6.23.
