From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
Hi folks,
This -v2 series addresses a long standing race between
fabric driver se_node_acl lookup + pointer dereference
during session login, and when kref_get() of ->acl_kref
actually happens within __transport_register_session()
code.
Also as reported earlier by HCH, go ahead and convert
core_tpg_set_initiator_node_queue_depth() to use proper
se_node_acl->se_acl_list -> se_session dereference,
following how core_tpg_del_initiator_node_acl() works
for invoking explicit session shutdown.
Please review,
--nab
-v2 changes:
- Have tcm_fc/ib_srpt conversion preceed other changes
- Fix demo-mode acl regression with generate_node_acls=1
- Fix set_initiator_node_queue_depth session reference
usage.
- Add ib_srpt hack to avoid potential user-space
backwards-compat issue.
Nicholas Bellinger (4):
tcm_fc: Convert acl lookup to modern get_initiator_node_acl usage
ib_srpt: Convert acl lookup to modern get_initiator_node_acl usage
target: Fix change depth se_session reference usage
target: Obtain se_node_acl->acl_kref during get_initiator_node_acl
