Subject: Re: [PATCH 2/2] integrity: double check iint_cache was initialized

Hi Mimi, Tetsuo, Kees, all,

FYI this commit merged as 92063f3ca73a ("integrity: double check iint_cache was initialized")
is the reason for openSUSE distro installer going back from lsm= to deprecated
security= when filling default grub parameters because security=apparmor or
security=selinux does not break boot when used with ima_policy=tcb, unlike
using lsm.

@Kees, @Mimi sure, people who use ima_policy=tcb will just remove lsm parameter
or add "integrity" to it but I wonder whether there could be "integrity"
automatic inclusion when using ima_policy=tcb. Although the point of lsm= (and
CONFIG_LSM) is to have *ordered* list of enabled LSMs and it wouldn't be clear
on which place.

Kind regards,
Petr
