0000208: kmod-nvidia-96xx module fails to load under CentOS 6

Notes
(0001326) dhungyel (reporter) 2011-12-10 03:11	When trying load driver by force by doing "modprobe nvidia" gives the following: FATAL: Error inserting nvidia (/lib/modules/2.6.32-131.17.1.el6.i686/weak-updates/nvidia-96xx/nvidia.ko): Accessing a corrupted shared library

(0001327) pperry (administrator) 2011-12-10 09:56	I've updated to the latest upstream sources. Packages will be available in the el6 testing repository shortly: http://elrepo.org/linux/testing/el6/ [^] kmod-nvidia-96xx-96.43.20-1.el6.elrepo.i686.rpm nvidia-x11-drv-96xx-96.43.20-1.el6.elrepo.i686.rpm kmod-nvidia-96xx-96.43.20-1.el6.elrepo.x86_64.rpm nvidia-x11-drv-96xx-32bit-96.43.20-1.el6.elrepo.x86_64.rpm nvidia-x11-drv-96xx-96.43.20-1.el6.elrepo.x86_64.rpm nvidia-96xx-kmod-96.43.20-1.el6.elrepo.nosrc.rpm nvidia-x11-drv-96xx-96.43.20-1.el6.elrepo.src.rpm Please test and let us know how you get on. Thanks.

(0001334) dhungyel (reporter) 2011-12-10 23:46	tested the new packages(96xx-96.43.20-1) from ELRepo. No luck there also. Problem is same as with the earlier package (96xx-96.43.19). The Xorg log reports FATAL error in accessing a corrupted shared library. Uninstalled the packages from ELRepo and tried with the binary from nVidia. The module builds but fails to load. nvidia-installer log reports that the Module Fails "ELF Checks". -- Dhungyel

(0001335) pperry (administrator) 2011-12-11 04:58	Thanks for reporting back. From what you describe, I'm certainly beginning to think the issue is your end rather than anything specific with the drivers / packages. For reference, here is dhungyel's forum thread with more information / logs: https://www.centos.org/modules/newbb/viewtopic.php?topic_id=34654&forum=57 [^]

(0001338) dhungyel (reporter) 2011-12-11 07:33	That thread in the CentOS support forum was created by me. I am not sure what the issue could be from my end. It is clean install of CentOS 6 with just the updates. The ELF check failure could be the issue with either the elf utilities, the driver itself or the Kernel (as my hardware is 10 years or older).

(0001766) AntonyKing (reporter) 2012-03-03 15:07	Hi, I discovered the aforementioned thread in the forum and discovered a way to solve the loading problem (for details see my posts 0000016 and #17 in the thread https://www.centos.org/modules/newbb/viewtopic.php?topic_id=34654&forum=57). [^] Any way it was recommended I post a patch, which I do have, and so I thought this would be the most appropriate place. The fix is as I described in the forum: the size specified by the n_namesz field in the elf32_note structures within the .note section in the object file usr/src/nv/nv-kernel.o need to be changed to the correct value to prevent an assertion failure being tripped during kernel module loading (the failure is in module_verify_elf () from kernel/module_verify_elf.c). The patch is in the form of a diff of xxd dumps of the original nv-kernel.o object file and the updated nv-kernel.o. To apply the patch perform the following: >>> cut here <<< sh NVIDIA-Linux-x86-96.43.20-pkg1.run -x cd NVIDIA-Linux-x86-96.43.20-pkg1/usr/src/nv xxd nv-kernel.o nv-kernel.o.xxd patch -i ../../../../nv-kernel.o.xxd.patch mv nv-kernel.o nv-kernel.o.orig xxd -r nv-kernel.o.xxd nv-kernel.o rm nv-kernel.o.xxd >>> cut here <<< After the patch has been applied the drivers can be built and installed as normal. Cheers, Antony.

(0001768) pperry (administrator) 2012-03-04 06:37	Many thanks Antony. Based on the information you have kindly provided I'm going to report this issue upstream to nvidia in the hope that they will fix it so we don't have to. The issue I have is that the license explicitly denies us permission to modify binary files (see below) so in my limited understanding, elrepo applying your patch and redistributing the modified binaries would break the license terms. From the LICENSE: 2.1.2 Linux/FreeBSD Exception. Notwithstanding the foregoing terms of Section 2.1.1, SOFTWARE designed exclusively for use on the Linux or FreeBSD operating systems, or other operating systems derived from the source code to these operating systems, may be copied and redistributed, provided that the binary files thereof are not modified in any way (except for unzipping of compressed files).

(0002245) chartness (reporter) 2012-05-17 08:34	PPerry, I wonder if you might have gotten any Joy out of this from NVIDIA ? I am reaching the same results with IBM Hardware, NVS 280 SD and CentOS 6.2 kernel 2.6.32-220.el6.i686 Thanks in Advance! Clark

(0002246) pperry (administrator) 2012-05-17 09:38	Hi Clark, As you can see from the link above, I've had no response from nvidia to the report I filed. Please feel free to add your weight in the above thread as that's probably our best chance of getting a response. As it's a legacy driver it would appear it's not high on their list of priorities, which I guess is understandable.

(0002247) chartness (reporter) 2012-05-17 10:50	Thanks Phil, I cross posted your NVNews post here: http://nvidia-submit.custhelp.com/app/account/questions/detail/i_id/422608 [^] Explaining you seemed to be getting no response @ NVNews so maybe we can get some response there.... I will also make a quick post here explaining I see the same issues with the IBM Hardware and the Quadro 280 Thanks Clark

(0002781) pperry (administrator) 2013-02-19 09:19	There are new upstream drivers (96.43.23) that _may_ fix this issue ?? I've built packages for el6 for these and released them to the el6 testing repository: kmod-nvidia-96xx-96.43.23-1.el6.elrepo.i686.rpm kmod-nvidia-96xx-96.43.23-1.el6.elrepo.x86_64.rpm nvidia-96xx-kmod-96.43.23-1.el6.elrepo.nosrc.rpm nvidia-x11-drv-96xx-32bit-96.43.23-1.el6.elrepo.x86_64.rpm nvidia-x11-drv-96xx-96.43.23-1.el6.elrepo.i686.rpm nvidia-x11-drv-96xx-96.43.23-1.el6.elrepo.nosrc.rpm nvidia-x11-drv-96xx-96.43.23-1.el6.elrepo.x86_64.rpm If anyone is able / willing to test and confirm they work (the kernel module now loads) then I'd much appreciate it.

(0002782) AntonyKing (reporter) 2013-02-21 07:39	I have tested kmod-nvidia-96xx-96.43.23-1.el6.elrepo.i686.rpm and nvidia-x11-drv-96xx-96.43.23-1.el6.elrepo.i686.rpm on Centos 6.3 (running on a Dell Precision 650); both packages installed OK and seem to be working AFAICT. (Note that I had previously installed the upstream package from NVIDIA but yum install did not complain so I assume everything went smoothly.)

(0002783) pperry (administrator) 2013-02-21 08:07	@AntonyKing Thank you very much for the feedback. To confirm it is indeed the elrepo packaged module that is loaded, please could you show the output from running: /sbin/modinfo nvidia Many thanks

(0002785) pperry (administrator) 2013-02-21 08:28	Thank you very much for the confirmation. The following shows the module is loaded correctly: % /sbin/modinfo nvidia filename: /lib/modules/2.6.32-279.22.1.el6.centos.plus.i686/weak-updates/nvidia-96xx/nvidia.ko Many thanks. We shall push this fix out to the main repo in due course and I'll mark this bug as resolved.
