@kernellogger I'd love to, but the main machine I would use has the openssl-hates-sha1 problem. Any easy way to work around that for just this run?

@klausman fedora or some other distro?

@klausman hmmm, can't reproduce that in a container that I just set up with distrobox, so for now I can't tell; will take a closer look later.

Found another problem while trying: compilation failed with "cc1: all warnings being treated as errors"; wonder why, CONFIG_WERROR is disabled; 'CFLAGS=-Wno-error' did not help either. Wonder what sorcery I'm missing. #sigh

@klausman ohh, and just to be sure: the error message is something like "Aborting: build would fail, as your distribution's OpenSSL policy apparently rejects SHA1 checksums by default. Compile […]", yes?

@kernellogger yes, exactly

@klausman some googling says that "CipherString = ALL@SECLEVEL=0" in /etc/ssl/openssl.cnf might help; is there a line similar to that already? I do not have it here in the container.

https://serverfault.com/questions/1143995/tls-1-0-broken-with-newer-debian-openssl

@kernellogger So I tried copying the system openssl.cnf, adding this to its end (the base file does not contain a line like it):

[system_default_sect]
CipherString = ALL:@SECLEVEL=0

and

export OPENSSL_CONF=$(pwd)/openssl.cnf

before running kcbench. It did not make the error go away. I don't know if the var makes it all the way down to the actual check or the env is cleared.

@klausman you likely have heard the answer to the "all the way down" a few times in your life already:

it should (but I haven't tried).

@kernellogger How much would just building a newer kernel throw off the tests?

@klausman I don't care about the results, I only want to know if everything works

@klausman yup; that -Werror comes from tools/objtool/Makefile and I have found no easy way to override this from Kcbench without modifying the sources (which I don't want to do).

So comping a newer version it is (5.17 seems to work)

@kernellogger I have tried to find a way to specify the kernel versionn, but --help showed nothing obvious. It also is aodd in that it claims:

On this machine kcbench by default will use a Linux kernel 6.8 configured
by 'make allmodconfig'.

but when starting it, it says:

Linux compiled: 5.15.0 [/home/klausman/.cache/kcbench/linux-5.15/]

So I am not sure there isn't something else that's off.

@klausman

"help showed nothing obvious" -> see screenshot.

@klausman that "On this machine kcbench by default will use a Linux kernel 6.8 configured" is a bug, thx!

heh, just started the same...

Run 1 (-j 96): 365.64 seconds / 9.85 kernels/hour [P:8354%, 5013 maj. pagefaults]

I had to show off the new machines at work

@klausman I wouldn't access the work machines at this time of day. Also, the biggest machines I could currently access would have only half the cores of that - but then, they're VMs anyway.

@kernellogger

```
Processor: AMD Ryzen 7 7840HS w/ Radeon 780M Graphics [16 CPUs]
Cpufreq; Memory: powersave [amd-pstate-epp]; 27849 MiB
Linux running: 6.10.13 [x86_64]
Compiler: gcc (Debian 12.2.0-14) 12.2.0
Linux compiled: 5.17.0 [/root/.cache/kcbench/linux-5.17]
Config; Environment: allmodconfig; CCACHE_DISABLE="1"
Build command: make vmlinux modules
```

and still running with `-j 16`.

@klausman @kernellogger

Aaaand then it failed.

```
Compilation failed. Aborting kcbench. Command used for compilation:
CCACHE_DISABLE="1" make --silent -C '/root/.cache/kcbench/linux-5.17' O='/tmp/kcbench.1YjKs0X4y/worker-0/' -j '16' vmlinux modules
```

A lot of "note:" and "warning:" in the "Tail from the output", but no errors.

@klausman @kernellogger

@wonka @klausman

that's unfortunate, but will happen sometimes; guess compiling an even newer kernel might do the trick (maybe try 6.8).

Might try to reproduce this here to add a check to catch this.

@kernellogger 6.8 fails too:

```
CCACHE_DISABLE="1" make --silent -C '/root/.cache/kcbench/linux-6.8' O='/tmp/kcbench.kBGChNXa5/worker-0/' -j '16' vmlinux modules
make[4]: *** [/root/.cache/kcbench/linux-6.8/kernel/Makefile:159: kernel/kheaders_data.tar.xz] Error 127
```

(About the "/root/": I'm running that in a podman container.)

@klausman

@wonka @klausman thx for testing; pretty sure that should be fixed now thx to https://gitlab.com/knurd42/kcbench/-/commit/da615f9a6b6f6197d42dde5beed183dfd65be646

@kernellogger Can confirm that the current HEAD script reports the correct kernel version in --help
