Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending

2015-04-24T17:22:09+00:00

Pull SCSI target updates from Nicholas Bellinger:
 "Lots of activity in target land the last months.

  The highlights include:

   - Convert fabric drivers tree-wide to target_register_template() (hch
     + bart)

   - iser-target hardening fixes + v1.0 improvements (sagi)

   - Convert iscsi_thread_set usage to kthread.h + kill
     iscsi_target_tq.c (sagi + nab)

   - Add support for T10-PI WRITE_STRIP + READ_INSERT operation (mkp +
     sagi + nab)

   - DIF fixes for CONFIG_DEBUG_SG=y + UNMAP file emulation (akinobu +
     sagi + mkp)

   - Extended TCMU ABI v2 for future BIDI + DIF support (andy + ilias)

   - Fix COMPARE_AND_WRITE handling for NO_ALLLOC drivers (hch + nab)

  Thanks to everyone who contributed this round with new features,
  bug-reports, fixes, cleanups and improvements.

  Looking forward, it's currently shaping up to be a busy v4.2 as well"

ib_srpt: convert printk's to pr_* functions

2015-04-15T20:06:54+00:00

The driver already defined the pr_format, it just hadn't
been converted to use pr_info, pr_warn, and pr_err instead
of the equivalent printks.  Convert so that messages from
the driver are now properly tagged with their driver name
and can be more easily debugged.

In addition, a number of these printk's were not newline
terminated, so fix that at the same time.

target: simplify the target template registration API

2015-04-14T19:28:41+00:00

Instead of calling target_fabric_configfs_init() +
target_fabric_configfs_register() / target_fabric_configfs_deregister()
target_fabric_configfs_free() from every target driver, rewrite the API
so that we have simple register/unregister functions that operate on
a const operations vector.

This patch also fixes a memory leak in several target drivers. Several
target drivers namely called target_fabric_configfs_deregister()
without calling target_fabric_configfs_free().

A large part of this patch is based on earlier changes from
Bart Van Assche .

(v2: Add a new TF_CIT_SETUP_DRV macro so that the core configfs code
can declare attributes as either core only or for drivers)

ib_srpt: wait_for_completion_timeout does not return negative status

2015-01-20T23:48:17+00:00

This patch changes srpt_close_session() to properly use an unsigned long
for wait_for_completion_timeout()'s return value, and to update WARN_ON()
to only trigger for a zero return.

srp-target: Retry when QP creation fails with ENOMEM

2014-10-28T20:55:08+00:00

It is not guaranteed to that srp_sq_size is supported
by the HCA. So if we failed to create the QP with ENOMEM,
try with a smaller srp_sq_size. Keep it up until we hit
MIN_SRPT_SQ_SIZE, then fail the connection.

ib_srpt: replace strnicmp with strncasecmp

2014-10-14T00:18:25+00:00

The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics and
a slightly buggy strncasecmp.  The latter is the POSIX name, so strnicmp
was renamed to strncasecmp, and strnicmp made into a wrapper for the new
strncasecmp to avoid breaking existing users.

To allow the compat wrapper strnicmp to be removed at some point in the
future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.

GID change events need a refresh just like LID change events and several
others.  Handle this the same as the others.
