      A recent change appears to have moved an #endif by accident:

Move it back to where it was previously.

      scsi: iscsi: Avoid potential deadlock in iscsi_if_rx func · bba340c7
      Bo Wu authored 
      In iscsi_if_rx func, after receiving one request through
iscsi_if_recv_msg func, iscsi_if_send_reply will be called to try to
reply to the request in a do-while loop.  If the iscsi_if_send_reply
function keeps returning -EAGAIN, a deadlock will occur.

For example, a client only send msg without calling recvmsg func, then
it will result in the watchdog soft lockup.  The details are given as
follows:

	sock_fd = socket(AF_NETLINK, SOCK_RAW, NETLINK_ISCSI);
	retval = bind(sock_fd, (struct sock addr*) & src_addr, sizeof(src_addr);
	while (1) {
		state_msg = sendmsg(sock_fd, &msg, 0);
		//Note: recvmsg(sock_fd, &msg, 0) is not processed here.
	}
	close(sock_fd);

      scsi: iscsi: Fix a potential deadlock in the timeout handler · 5480e299
      Bart Van Assche authored 
      Some time ago the block layer was modified such that timeout handlers are
called from thread context instead of interrupt context. Make it safe to
run the iSCSI timeout handler in thread context. This patch fixes the

      scsi: libsas: stop discovering if oob mode is disconnected · f70267f3
      Jason Yan authored 
      The discovering of sas port is driven by workqueue in libsas. When libsas
is processing port events or phy events in workqueue, new events may rise
up and change the state of some structures such as asd_sas_phy.  This may
cause some problems such as follows:

==>thread 1                       ==>thread 2

                                  ==>phy up
                                  ==>phy_up_v3_hw()
                                    ==>oob_mode = SATA_OOB_MODE;
                                  ==>phy down quickly
                                  ==>hisi_sas_phy_down()
                                    ==>sas_ha->notify_phy_event()
                                    ==>sas_phy_disconnected()
                                      ==>oob_mode = OOB_NOT_CONNECTED
==>workqueue wakeup
==>sas_form_port()
  ==>sas_discover_domain()
    ==>sas_get_port_device()
      ==>oob_mode is OOB_NOT_CONNECTED and device
         is wrongly taken as expander

This at last lead to the panic when libsas trying to issue a command to
discover the device.

      scsi: ufs: Disable autohibern8 feature in Cadence UFS · d168001d
      sheebab authored 
      This patch disables autohibern8 feature in Cadence UFS.  The autohibern8
feature has issues due to which unexpected interrupt trigger is happening.
After the interrupt issue is sorted out, autohibern8 feature will be
re-enabled

      scsi: iscsi: qla4xxx: fix double free in probe · fee92f25
      Dan Carpenter authored 
      On this error path we call qla4xxx_mem_free() and then the caller also
calls qla4xxx_free_adapter() which calls qla4xxx_mem_free().  It leads to a
couple double frees:

drivers/scsi/qla4xxx/ql4_os.c:8856 qla4xxx_probe_adapter() warn: 'ha->chap_dma_pool' double freed
drivers/scsi/qla4xxx/ql4_os.c:8856 qla4xxx_probe_adapter() warn: 'ha->fw_ddb_dma_pool' double freed

      Pull orangefs update from Mike Marshall:
 "orangefs: posix open permission checking...

  Orangefs has no open, and orangefs checks file permissions on each
  file access. Posix requires that file permissions be checked on open
  and nowhere else. Orangefs-through-the-kernel needs to seem posix
  compliant.

  The VFS opens files, even if the filesystem provides no method. We can
  see if a file was successfully opened for read and or for write by
  looking at file->f_mode.

  When writes are flowing from the page cache, file is no longer
  available. We can trust the VFS to have checked file->f_mode before
  writing to the page cache.

  The mode of a file might change between when it is opened and IO
  commences, or it might be created with an arbitrary mode.

  We'll make sure we don't hit EACCES during the IO stage by using
  UID 0"

[ This is "posixish", but not a great solution in the long run, since a
  proper secure network server shouldn't really trust the client like this.
  But proper and secure POSIX behavior requires an open method and a
  resulting cookie for IO of some kind, or similar.    - Linus ]
