scsi: fcoe: Embed fc_rport_priv in fcoe_rport structure

2019-08-09T15:51:41+00:00

commit 023358b136d490ca91735ac6490db3741af5a8bd upstream.

Gcc-9 complains for a memset across pointer boundaries, which happens as
the code tries to allocate a flexible array on the stack.  Turns out we
cannot do this without relying on gcc-isms, so with this patch we'll embed
the fc_rport_priv structure into fcoe_rport, can use the normal
'container_of' outcast, and will only have to do a memset over one
structure.

scsi: fcoe: make use of fip_mode enum complete

2019-02-19T23:58:38+00:00

commit 1917d42d14b7 ("fcoe: use enum for fip_mode") introduces a separate
enum for the fip_mode that shall be used during initialisation handling
until it is passed to fcoe_ctrl_link_up to set the initial fip_state.  That
change was incomplete and gcc quietly converted in various places between
the fip_mode and the fip_state enum values with implicit enum conversions,
which fortunately cannot cause any issues in the actual code's execution.

clang however warns about these implicit enum conversions in the scsi
drivers. This commit consolidates the use of the two enums, guided by
clang's enum-conversion warnings.

This commit now completes the use of the fip_mode: It expects and uses
fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls
fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up().  It
also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to
indicate these two enums are distinct.

scsi: fcoe: remove unneeded fcoe_ctlr_destroy_store export

2019-01-29T05:30:50+00:00

There's no need to export fcoe_ctlr_destroy_store as a symbol, so remove
the EXPORT_SYMBOL() line for it.

scsi: fcoe: convert to use BUS_ATTR_WO

2019-01-29T05:29:30+00:00

We are trying to get rid of BUS_ATTR() and the usage of that in the fcoe
driver can be trivially converted to use BUS_ATTR_WO(), so use that
instead.

scsi: flip the default on use_clustering

2018-12-19T04:13:12+00:00

Most SCSI drivers want to enable "clustering", that is merging of
segments so that they might span more than a single page.  Remove the
ENABLE_CLUSTERING define, and require drivers to explicitly set
DISABLE_CLUSTERING to disable this feature.

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2018-08-16T05:06:26+00:00

Pull SCSI updates from James Bottomley:
 "This is mostly updates to the usual drivers: mpt3sas, lpfc, qla2xxx,
  hisi_sas, smartpqi, megaraid_sas, arcmsr.

  In addition, with the continuing absence of Nic we have target updates
  for tcmu and target core (all with reviews and acks).

  The biggest observable change is going to be that we're (again) trying
  to switch to mulitqueue as the default (a user can still override the
  setting on the kernel command line).

  Other major core stuff is the removal of the remaining Microchannel
  drivers, an update of the internal timers and some reworks of
  completion and result handling"
