Hello Ard Biesheuvel,
This is a semi-automatic email about new static checker warnings.
The patch 19483677684b: "jump_label: Annotate entries that operate on
__init code earlier" from Sep 18, 2018, leads to the following Smatch
complaint:
kernel/jump_label.c:524 __jump_label_mod_update()
error: we previously assumed 'm' could be null (see line 519)
kernel/jump_label.c
518 m = mod->mod;
519 if (!m)
^^
Old code has check for NULL
520 stop = __stop___jump_table;
521 else
522 stop = m->jump_entries + m->num_jump_entries;
523 __jump_label_update(key, mod->entries, stop,
524 m->state == MODULE_STATE_COMING);
^^^^^^^^
New code adds unchecked dereference.
525 }
526 }
regards,
dan carpenter
