Jarkko,
are you ok with this patch?
Hmmm, hope I did not miss anythng, but looks like nothing happened for
about 10 days here. Hence:
Jarkko, looks like some feedback from your side really would help to
find a path to get this regression resolved before 6.10 is released.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
Sorry for latency, and except a bit more slow phase also during
July because I'm most of this month on Holiday, except taking care
6.11 release.
This really is a bug in the HMAC code not in the IBM driver as
it should not break because of a new feature, i.e. this is only
correct conclusions, give the "no regressions" rule.
Since HMAC is by default only for x86_64 and it does not break
defconfig's, we should take time and fix the actual issue.
It was enabled it on my ppc64 system after a git pull -- at least I did
not enable it explicitly. Besides that others can enable it on any arch
unless you now change the 'default x86_64' to a 'depends x86_64' iiuc
otherwise the usage of a Fixes: , as I used in my patch, would be justified.
config TCG_TPM2_HMAC
bool "Use HMAC and encrypted transactions on the TPM bus"
default X86_64
select CRYPTO_ECDH
select CRYPTO_LIB_AESCFB
select CRYPTO_LIB_SHA256
