Commit 77debf316c44 ("LFV-26 crypto: caam - fix Secure Memory driver init")
|
|
addressed SM driver initialization and also update SM test.
|
|
|
|
However, the fix for SM test is insufficient.
|
|
There are cases when SM test runs before SM driver, causing a crash
|
|
due to uninitialized "priv" pointer being dereferenced.
|
|
|
|
The fix consists in the following:
|
|
|
|
1. Since SM test is a "bare" device driver (doesn't sit on any bus),
|
|
there is no deferred probing support.
|
|
Thus we have no choice (*) but to abort SM tests with a notification.
|
|
|
|
(*) We don't want to force SM driver running first by means of
|
|
init levels etc. Just KISS.
|
|
|
|
2. SM test driver forced to being built only as a module
|
|
Since SM test driver's only goal is to run SM tests, it doesn't make
|
|
any sense to be built-in.
|
|
Building the driver as a module allows for running the tests
|
|
several times if needed (multiple modprobe & rmmod cycles).
|
|
|
|
Note: from the perspective of wanting to test repetitively, it would
|
|
make sense to force module unloading by returning an error code
|
|
in the module_init function.
|
|
However, this might affect test scripts (due to error code and/or
|
|
message output by unsuccessful module loading), so we postpone
|
|
this change for now.
|
