Bug ID: 1206833 Summary: Cannot load KMPs on armv7 Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.4 Hardware: armv7 OS: openSUSE Leap 15.4 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: james.hobson@oriel.ox.ac.uk QA Contact: qa-bugs@suse.de Found By: --- Blocker: ---
KMPs do not load on OpenSuse Leap 15.4 on armv7.
This because the kernel-default/lpae package exports: Provides: ksym(...) = 5f For all kernel symbols, but kernel symbols are calculated correctly for KMP packages e.g. ksym(default:PDE_DATA) = 22e390 (made up hash)
This means that when you install a KMP package with zypper, it says that it cannot resolve dependencies.
More worryingly, this breaks OBS kiwi builds for the armv7 platform

--- Comment #2 from Michal Suchanek msuchanek@suse.com --- The tooling seems to work on TW:
localhost:~ # /usr/src/linux-6.0.12-1-obj/armv7hl/lpae/scripts/mod/ksym-provides lpae /lib/modules/6.0.12-1-default/kernel/lib/crc7.ko ksym(lpae:crc7_be) = 7fffffff ksym(lpae:crc7_be_syndrome_table) = 65aaf037

--- Comment #4 from James Hobson james.hobson@oriel.ox.ac.uk --- Is there any movement on this bug? anything I can do?

--- Comment #5 from Michal Suchanek msuchanek@suse.com --- perhaps provide the output of
echo /lib/modules/*/kernel/lib/crc7.ko | /usr/lib/rpm/find-provides.ksyms

--- Comment #6 from James Hobson james.hobson@oriel.ox.ac.uk --- Sadly I'm running a very modified appliance with a custom kernel and I don't have that file.
localhost:~ # echo /lib/modules/5.14.21-lp154.84.g49db222-default/pvrsrvkm.ko | /usr/lib/rpm/find-provides.ksyms error: cannot determine ksym provides of /lib/modules/5.14.21-lp154.84.g49db222-default/pvrsrvkm.ko - missing ksym-provides tool. kmod(pvrsrvkm.ko)
I have run this. I don't know if my system is missing something or weather this is the bug

--- Comment #7 from James Hobson james.hobson@oriel.ox.ac.uk --- Found an armv7 device running vanilla Leap 15.4:
tellurium-128:~ # echo /lib/modules/5.14.21-22-lpae/kernel/lib/crc7.ko.zst | /usr/lib/rpm/find-provides.ksyms error: cannot determine ksym provides of /tmp/tmp.l9DGd9H9qB.ko - missing ksym-provides tool. kmod(crc7.ko)
Same error!
But I'm not sure if the fact that the module is compressed matters?

--- Comment #9 from James Hobson james.hobson@oriel.ox.ac.uk ---
kernel-default-devel that includes the tool for build
How do I build one of these? Both the default one and my custom one doesn't have this tool

--- Comment #10 from Michal Suchanek msuchanek@suse.com --- it does /usr/src/linux-5.14.21-24.39-obj/armv7hl/default/scripts/mod/ksym-provides

--- Comment #11 from James Hobson james.hobson@oriel.ox.ac.uk --- Sorry, I've got myself confused so I'm rewinding :) If I install Leap 15.4 (armv7) fresh, I can't install any modules from zipper in the default repos, nor can I build any.
Is there any way to build the kernel to generate the Provides correctly?

--- Comment #12 from Michal Suchanek msuchanek@suse.com --- There probably isn't, there is some bug in generating those dependencies.
However, running the ksym-provides tool and the dependency generator on Tumbleweed does not show any obvious problem.
