Description Manfred Hollstein 2023-10-09 08:25:17 UTC

The recently updated binutils in openSUSE_Leap_15.4 generate new DT_ tags which dwarves does not know about:

[ 1122s] Unsupported DW_TAG_unspecified_type(0x3b)
[ 1122s] Encountered error while encoding BTF.

osc branch --nodevelproject openSUSE:Factory dwarves Kernel:stable:Backport

would probably solve this issue.

Comment 1 Jiri Slaby 2023-10-09 08:58:32 UTC

IMO dwarves should be updated to 1.25 in Leap, so that it can handle updated tags which the new binutils generate.

Comment 2 Jiri Slaby 2023-10-09 09:04:15 UTC

(Forgot to note that I temporarily worked around this by linking dwarves from Factory (1.25) to Kernel:stable:Backport.)

Comment 3 Michal Suchanek 2023-10-09 09:44:20 UTC

dwarves is part of SLE so it needs to be updated there, and SLE does not have the required libraries for that.

The current dwarves can be only built with vendored libbpf.

OTOH 1.25 builds fine in Kernel:stable:Backport, i.e. against Leap:15.5:Update (it was :15.4: yesterday before Takashi did the switch and was OK too). I didn't check SLE, but does Leap have enough and SLE not?

Comment 6 Michal Suchanek 2023-10-10 11:29:22 UTC

No, it's built with vendored libbpf which probably works but is unfit for releasing in SLE.

Comment 9 Andreas Stieger 2024-04-06 06:35:57 UTC

Seen on 15.5

Comment 10 Bob Goddard 2024-04-10 14:14:49 UTC

This is also a problem in 15.5.

Is this going to be fixed, or do we have to wait until 16 which is over a year away?

Comment 11 Michal Suchanek 2024-04-10 14:22:43 UTC

dwarves are updated in 15.6

I do not think it is acceptable that we have to wait until 15.6 for a fix.

It is NOT acceptable that this issue is not being fixed.

The inability to build a kernel should not be left until 15.6.

Comment 14 Michal Suchanek 2024-05-09 13:59:54 UTC

You can install the build tools from Kernel:stable:Backport project as well as the prebuilt kernels.

In 15.6 dwarves is new enough to build the upstream kernel out of the box, for now.

That is NOT acceptable.

We should not have to go through hoops & I am sure as heck NOT going to install a whole bunch of other packages..

I just tried to install from https://download.opensuse.org/repositories/Kernel:/stable:/Backport/standard/aarch64/ & there is no build tools or any dwarves package listed.
