WARNING:at_crypto/kdf_sp800108.c:#crypto_kdf108_init
(please be noted we reported this commit as
"[security] d3b04a4398: WARNING:at_crypto/kdf_sp800108.c:#crypto_kdf108_init"
when it's on linux-next/master
https://lists.01.org/hyperkitty/list/lkp@lists.01.org/thread/5B23YXI7UOBEBJXXKHV2SPDN7PUE7RW7/
where we saw discussion about solution.
since now it's on mainline and the issue still exists, we reported this again
as a reminder)
Greeting,
FYI, we noticed the following commit (built with clang-14):
commit: d3b04a4398fe8022c9ca4b5ac6ab08059334b180 ("security: DH - use KDF implementation from crypto API")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: boot
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 16G
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag
