Bug#1066883: alg: ecdh-nist-p256: test failed on vector 2, err=-14
Source: linux
Severity: important
Same as: Bug #1061262
I've been seeing this with builds since 6.7 cycle started. It seems to
show up mostly for hosts with bluetooth hardware since the bluetooth
module depends on ecdh. The trace indicates ecdh_generic is still
loading when the test is attempted.
journalctl --grep 'alg: self-tests for ecdh-nist-p256' |
grep -- '-- Boot' |
while read -r a b hash d; do
journalctl --boot $hash | head -n 1 |
grep -oE 'version [^ ]+'
done |
sort -u

version 6.7.4+debian+tj
version 6.8.0+debian+tj
crypto algo self-tests 'alg: ecdh-nist-p256: test failed on vector 2, err=-14
-14 is "EFAULT 14 / Bad address */
and the log shows
Modules linked in: ecdh_generic(+) ...
where the "(+)" means module loading.
This only seems to occur on hosts with Bluetooth hardware and "bluetooth" module (requires ECDH) when those modules are in the initrd.img.
It feels like the self-tests are running before the module is fully loaded - in fact the tcrypt module (CONFIG_CRYPTO_TEST) isn't loaded according to "Modules linked in:" report and it isn't contained in the initrd.img so these tests seem to be occuring without it.
