4f6b206998 scsi: elx: libefc: Fix second parameter type in state callbacks 
[ Upstream commit 3d75e766b58a7410d4e835c534e1b4664a8f62d0 ]

With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function pointer
prototype to make sure the call target is valid to help mitigate ROP
attacks. If they are not identical, there is a failure at run time, which
manifests as either a kernel panic or thread getting killed. A proposed
warning in clang aims to catch these at compile time, which reveals:

  drivers/scsi/elx/libefc/efc_node.c:811:22: error: incompatible function pointer types assigning to 'void (*)(struct efc_sm_ctx *, u32, void *)' (aka 'void (*)(struct efc_sm_ctx *, unsigned int, void *)') from 'void (*)(struct efc_sm_ctx *, enum efc_sm_event, void *)' [-Werror,-Wincompatible-function-pointer-types-strict]

                                    ^ ~~~~~

The type of the second parameter in the prototypes of ->current_state() and
->nodedb_state() ('u32') does not match the implementations, which have a
second parameter type of 'enum efc_sm_event'. Update the prototypes to have
the correct second parameter type, clearing up all the warnings and CFI
failures.

[ Upstream commit bb0cd225dd37df1f4a22e36dad59ff33178ecdfc ]

In efct_device_init(), when efct_scsi_reg_fc_transport() fails,
efct_scsi_tgt_driver_exit() is not called to release memory for
efct_scsi_tgt_driver_init() and causes memleak:

commit 61263b3a11a2594b4e898f166c31162236182b5c upstream.

GFP_KERNEL/GFP_DMA can't be used under a spin lock. According the comment,
els_ios_lock is used to protect els ios list so we can move down the spin
lock to avoid using this flag under the lock.

450907424d scsi: elx: efct: Do not hold lock while calling fc_vport_terminate() 
Smatch checker reported the following error:

  drivers/base/power/sysfs.c:833 dpm_sysfs_remove()
  warn: sleeping in atomic context

With a calling sequence of:

  efct_lio_npiv_drop_nport() <- disables preempt
  -> fc_vport_terminate()
     -> device_del()
        -> dpm_sysfs_remove()

Issue is efct_lio_npiv_drop_nport() is making the fc_vport_terminate() call
while holding a lock w/ ipl raised.

It is unnecessary to hold the lock over this call, shift where the lock is
taken.

96fafe7c65 scsi: elx: efct: Fix void-pointer-to-enum-cast warning for efc_nport_topology 
The kernel test robot flagged an warning for ".../efc_device.c:932:6:
warning: cast to smaller integer type 'enum efc_nport_topology' from 'void
*'"

For the topology events, the "arg" field is generically defined as a void *
and is used to pass different arguments. Most of the arguments are pointers
to data structures. But for the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event, the
argument is an enum value, and the code is typecasting the void * to an
enum generating the warning.

Fix by converting the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event to pass a pointer
to the enum, thus it's a straight-forward pointer dereference in the event
handler.

 - Creation of the sessions subdirectory. Modify this creation to create
   under the initial directory created, and fix failure check.
