Subject: Re: [PATCH v5 1/1] security: Add mechanism to safely (un)load LSMs after
boot time
Suggested changes on top of your patch:
Replace "struct hlist_head *head" in "struct security_hook_list" with
"const unsigned int offset" because there is no need to initialize with
address of the immutable/mutable chains.
Remove LSM_HOOK_INIT_MUTABLE() by embedding just offset (in bytes) from
head of "struct security_hook_heads" into "struct security_hook_list"->offset.
Make "struct security_hook_heads security_hook_heads" and
"struct security_hook_heads security_hook_heads_mutable" local variables.
Rename "struct security_hook_heads security_hook_heads" to
"struct security_hook_heads security_mutable_hook_heads" and mark it as
__ro_after_init.
Add the fourth argument to security_add_hooks() which specifies to which
chain (security_{mutable|immutable}_hook_heads) to connect.
Make all built-in LSM modules (except SELinux if
CONFIG_SECURITY_SELINUX_DISABLE=y) be connected to
security_immutable_hook_heads.
Rename __lsm_ro_after_init to __selinux_ro_after_init which is local to
SELinux.
Mark "struct security_hook_list"->hook const because it won't change.
Mark "struct security_hook_list"->lsm const because none of
security_add_hooks() callers are ready to modify the third argument.
Remove SECURITY_HOOK_COUNT and "struct security_hook_list"->owner and
the exception in randomize_layout_plugin.c because preventing module
unloading won't work as expected.
