Hello,

with kernels from fedora-rawhide-kernel-nodebug [1]compilation of kmods
 started fail because [2]  , how we can fix this issue ? 


Thanks

Hi,

we're seeing a similar issue with upstream kernels built on rawhide
for the past ~week.

Specifically in our case we're compiling bpf-next tree (though based
on the message I'm replying to it doesn't matter). The kernel is then
installed on Fedora 33 with an attempt to rebuild some modules which
fails with

/usr/src/kernels/5.10.0-rc3/tools/objtool//fixdep: /lib64/libc.so.6:
version `GLIBC_2.33' not found (required by
/usr/src/kernels/5.10.0-rc3/tools/objtool//fixdep)

This is on x86_64.

Did anyone manage to find out what what's causing this? Is it a
mismatch of versions between rawhide and fc33 that's not expected to
work? @Sérgio are you also using the kernels with fc33 or purely
rawhide?


Thanks,
Veronika

Sometimes when I want test builds of kernel modules (with akmods of
RPMFusion), I install kernels from fedora-rawhide-kernel-nodebug
or kernel-stabilization . 
I workaround it, by building the kernels that I want to test on copr
[1] for that I download src.rpm from koji .

Thanks for the update! Unfortunately building in copr doesn't work
for us.

ccing Don and Justin, have you ever run into this issue with
building on rawhide?

A mismatch of modules is definitely expected not to work. Fedora runs
without CONFIG_MODVERSIONS because we do not in any way promise KABI.
Because of this, if you want to run a module, it must be built with
the same compiler/environment that the kernel you wish to insert it
into is built.  If you need out of tree modules, rawhide/nodebug
kernels will need to be run in rawhide, or rebuilt against the version
of Fedora you wish to run it on.

I have not seen any issues, though I don't build any out of tree modules either.

I think [1] make it work , the problem is these binaries (fixdep,
objtool and modpost)  that are compiled in rawhide with a new glibc
... 

[1] 
cp /usr/src/kernels/5.9.9-100.fc32.x86_64/scripts/basic/fixdep
/usr/src/kernels/5.10.0-0.rc6.90.fc34.x86_64/scripts/basic/

Hi,

As the copy didn't work, I tried this [2] that worked for me, ie akmods
build kmod successfully for 5.10.0-0.rc7.20201211git33dc9614dc2

[2]
cd /usr/src/kernels/5.10.0-0.rc7.20201211git33dc9614dc20.97.fc34.x86_64
rm tools/objtool/fixdep scripts/basic/fixdep
tools/bpf/resolve_btfids/fixdep 
cd tools/
make objtool
cd ..
make (I think just need to build fixdep again)

interesting. For us the problem appeared as we were trying to rebuild
fixdep and a few other tools. Instead of trying to add more workarounds
we moved on the fix Justin suggested, not mixing rawhide and fc33 --
we did that for a good year and everything worked until now but if
it's not officially supported then we may run into future problems too.
The errors are gone with that step.
