Description David Anderson 2006-05-18 13:11:27 UTC
Though this issue involves Livna/Madwifi, it's not Livna/Madwifi-specific - it will apply to any packager of any kernel modules. I have a machine with two kernels installed, running the latter: kernel-2.6.16-1.2096_FC5 kernel-2.6.16-1.2111_FC5 Also, I have the two corresponding madwifi kernel modules (from Livna) installed (with apologies to any crazed FSF zealots): kmod-madwifi-0.0.0.20060317-184.108.40.206_1.2096_FC5 kmod-madwifi-0.0.0.20060317-220.127.116.11_1.2111_FC5 Then, Livna release an updated package for the running kernel: kmod-madwifi-0.0.0.20060317-18.104.22.168_1.2111_FC5 When I run "yum update", yum suggests to remove kmod-madwifi-0.0.0.20060317-22.214.171.124_1.2096_FC5, thus leaving me with: kernel-2.6.16-1.2096_FC5 kernel-2.6.16-1.2111_FC5 kmod-madwifi-0.0.0.20060317-126.96.36.199_1.2111_FC5 kmod-madwifi-0.0.0.20060317-188.8.131.52_1.2111_FC5 i.e. Leave me with two different kernels, but two madwifi modules for the same kernel. Not very useful! I then tried running yum with --noplugins. It still offers to install the new kmod-madwifi for kernel 2111 without removing the old one. These two kernel modules then both install, owning the same files, which differ only by timestamp. That doesn't matter, I suppose (nothing breaks), but it's clearly not desired behaviour. What should happen: installonlyn seems to have a check that it doesn't remove packages relating to the running kernel. This should be made more subtle: it should not remove a package for the running kernel if no other package for the same kernel will remain. In my case, this means that it would have been happy to remove kmod-madwifi-0.0.0.20060317-184.108.40.206_1.2111_FC5 because kmod-madwifi-0.0.0.20060317-220.127.116.11_1.2111_FC5 is about to be installed. I suspect that this, though a good step, isn't enough, as it will still suggest to remove the oldest package (the 2096 kernel one). Whatever mechanism in yum decides to install instead of updating kernel-related packages should also be modified somehow. I'm not sure how. It seems that the newer Livna packages have a "Provides: kernel-modules = <kernel-version>" that presumably is meant to deal with this same problem, so maybe that's already being taken care of.

Today you can view the same phenomena with kmod-nvidia from the same source.

Comment 2 Jeremy Katz 2006-05-22 17:05:27 UTC
Do you have the fedorakmod plugin installed?
Comment 3 David Anderson 2006-05-23 09:09:02 UTC
No, I don't - should I? I've not heard of that. Today I see there's a new kernel released, and "yum update" is offering both to _install_ and _update_ the very same RPM for madwifi (though not nvidia): [david@shed ~]$ rpm -q kmod-nvidia kmod-nvidia-1.0.8756-184.108.40.206_1.2096_FC5 kmod-nvidia-1.0.8756-220.127.116.11_1.2111_FC5 kmod-nvidia-1.0.8756-18.104.22.168_1.2111_FC5 [david@shed ~]$ rpm -q kmod-madwifi kmod-madwifi-0.0.0.20060317-22.214.171.124_1.2096_FC5 kmod-madwifi-0.0.0.20060317-126.96.36.199_1.2111_FC5 kmod-madwifi-0.0.0.20060317-188.8.131.52_1.2111_FC5 [david@shed ~]$ su - Password: [root@shed ~]# yum update Loading "installonlyn" plugin Loading "fastestmirror" plugin Setting up Update Process (snip) ============================================================================= Package Arch Version Repository Size ============================================================================= Installing: kernel i686 2.6.16-1.2122_FC5 updates 13 M kernel-devel i686 2.6.16-1.2122_FC5 updates 4.7 M kmod-madwifi i686 0.0.0.20060520-184.108.40.206_1.2122_FC5 livna 234 k kmod-nvidia i686 1.0.8756-220.127.116.11_1.2122_FC5 livna 1.6 M Updating: (snip) madwifi i386 0.0.0.20060520-6.lvn5 livna 214 k (snip) Removing: kernel i686 2.6.16-1.2096_FC5 installed 34 M kernel-devel i686 2.6.16-1.2096_FC5 installed 14 M kmod-madwifi i686 0.0.0.20060317-18.104.22.168_1.2111_FC5 installed 557 k kmod-madwifi i686 0.0.0.20060317-22.214.171.124_1.2096_FC5 installed 557 k kmod-nvidia i686 1.0.8756-126.96.36.199_1.2096_FC5 installed 4.9 M kmod-nvidia i686 1.0.8756-188.8.131.52_1.2111_FC5 installed 4.9 M Installing for dependencies: ImageMagick-c++ i386 184.108.40.206-4.2.1 core 141 k Updating for dependencies: kmod-madwifi i686 0.0.0.20060520-220.127.116.11_1.2122_FC5 livna 234 k Transaction Summary ============================================================================= Install 5 Package(s) Update 18 Package(s) Remove 6 Package(s) Total download size: 41 M Note that kmod-nvidia 0.0.0.20060520-18.104.22.168_1.2122_FC5 appears both as an update and as a new installation.

Sorry, that last line should say "kmod-madwifi".

Comment 5 David Anderson 2006-05-23 09:49:12 UTC
A subsequent run of "yum update" then succeeds (and installs kmod-madwifi - doesn't 'update' it).
Comment 6 David Anderson 2006-05-25 14:59:05 UTC
OK, it looks like yum-fedorakmod is something I should have. So I installed it. This seems to fix the _initial_ problem (a new kmod-nvidia is released today, and yum now correctly suggests to install the new one and remove the old one) (which seems equivalent to updating the old one - presumably there's a reason why it _doesn't_ just update the old one). Should I file a bug at Livna to suggest that kmod-* packages should Require: yum-fedorakmod ???
Comment 7 David Anderson 2006-05-25 15:05:06 UTC
No, I'm wrong. It hasn't fixed the initial problem. It's not offering to retain just one kmod-X package for the currently installed kernel - it's offering to leave me with two kmod-X packages for the current kernel, and none for the other installed kernel, just as before. Sorry about that - I misread it. Here's what I get this time on a "yum update": [root@shed ~]# yum update Loading "installonlyn" plugin Loading "fastestmirror" plugin Loading "fedorakmod" plugin Setting up Update Process Setting up repositories (snip) Dependencies Resolved ============================================================================= Package Arch Version Repository Size ============================================================================= Installing: kmod-nvidia i686 1.0.8762-184.108.40.206_1.2122_FC5 livna 1.6 M Updating: (snip) xorg-x11-drv-nvidia i386 1.0.8762-2.lvn5 livna 4.0 M Removing: kmod-nvidia i686 1.0.8756-220.127.116.11_1.2111_FC5 installed 4.9 M Here's what I had installed before running "yum update": [root@shed cups]# rpm -q kmod-nvidia kmod-nvidia-1.0.8756-18.104.22.168_1.2111_FC5 kmod-nvidia-1.0.8756-22.214.171.124_1.2122_FC5 [root@shed cups]# rpm -q kernel kernel-2.6.16-1.2111_FC5 kernel-2.6.16-1.2122_FC5 [root@shed cups]# rpm -q yum-fedorakmod yum-fedorakmod-0.6-2.fc5 However, I believe this may be because of the interdependency with xorg-x11-drv-nvidia which has had its version bumped, so this probably doesn't count as a real case.
Comment 8 David Anderson 2006-06-19 17:44:44 UTC
Here's a further datapoint. Today there was a kmod-madwifi update available (from 0.0.0.20060520-126.96.36.199_1.2133_FC5 to 0.9.0-188.8.131.52_1.2133_FC5). I have the fedora kmod yum plugin installed. yum again offers to do the wrong thing (i.e. remove the kmod for the old kernel, and install (not update) for the new kernel). I then tried with pup instead. It claimed it was going to do the right thing (i.e. when you click for more details, it says it is "updating" the kmod for the existing kernel), but after running the transaction, it transpires that it didn't do what it claimed - it did the wrong thing and left me with two kmods for a single kernel and none for the other kernel. Afterwards: [root@shed ~]# rpm -q kmod-madwifi kmod-madwifi-0.0.0.20060520-184.108.40.206_1.2133_FC5 kmod-madwifi-0.9.0-220.127.116.11_1.2133_FC5

This should all be working well AFAIK with fc6
