[SCSI] iscsi class: sysfs group is_visible callout for iscsi host attrs
The iscsi class currently does not support writable sysfs
attrs for LLD sysfs settings. This patch converts the
iscsi class and driver's host attrs to use the attribute
container sysfs group and the sysfs group's is_visible callout
to be able to support readable or writable sysfs attrs.

iscsi: Resolve iscsi_proto.h naming conflicts with drivers/target/iscsi
This patch renames the following iscsi_proto.h structures to avoid
namespace issues with drivers/target/iscsi/iscsi_target_core.h:
*) struct iscsi_cmd -> struct iscsi_scsi_req
*) struct iscsi_cmd_rsp -> struct iscsi_scsi_rsp
*) struct iscsi_login -> struct iscsi_login_req
This patch includes useful ISCSI_FLAG_LOGIN_[CURRENT,NEXT]_STAGE*,
and ISCSI_FLAG_SNACK_TYPE_* definitions used by iscsi_target_mod, and
fixes the incorrect definition of struct iscsi_snack to following
RFC-3720 Section 10.16. SNACK Request.
Also, this patch updates libiscsi, iSER, be2iscsi, and bn2xi to
use the updated structure definitions in a handful of locations.

[SCSI] bnx2i: Added the use of kthreads to handle SCSI cmd completion
This patch breaks the SCSI cmd completion into two parts:
1. The bh will allocate and queued work to the cmd specific CPU IO
completion kthread. The CPU for the cmd is from the sc->request->cpu.
2. The CPU specific IO completion kthread will call the scsi_cmd_resp
routine to do the actual cmd completion.
In the normal case, these IO completion kthreads should complete before
the blk IO times out at 60s. However, in the case when these kthreads
are blocked for whatever reason and exceeded the timeout, the call
to conn_destroy will have to iterate and exhaust all related work in the
percpu work list for all online CPUs. This will guarantee the protection
of the work->session and conn pointers before they get freed.
Also modified the event coalescing formula to have at least the
event_coal_min outstanding cmds in the pipeline so the SCSI producer
would not get underrun.
Also changed the following SCSI parameters:
- can_queue from 1024 to 2048
- cmds_per_lun from 24 to 128

[SCSI] bnx2i: Optimized the iSCSI offload performance
Modified the event coalescing code for iSCSI offload to combat both
corner cases and optimize performance as follows:
1. Added mechanism to loop back a second time to process any leftover
CQEs that was generated by the hardware during the time the driver is
busy processing previous CQEs in the bh. This not only helps the
performance but also fixes the corner case when no more CQEs are being
generated in the pipeline; so those leftover CQEs will get a a chance
to be processed.
2. Added ARM_CQE_FP to distinguish between fast path arming versus
slow path arming. This change will guarantee that the CQEs will
always get a chance to be re-armed during fast path completions.
3. Removed the inline event coalescing division for perf optimization.
Also fixed a division-by-zero error when the event_coal_div module
param was set to 0.
4. Changed the default SQ WQEs size from 256 to 128 to match chip
default.
5. Changed the cmd_per_lun from 32 to 24.

[SCSI] bnx2i: Fixed packet error created when the sq_size is set to 16
The number of chip's internal command cell, which is use to generate
SCSI cmd packets to the target, was not initialized correctly by
the driver when the sq_size is changed from the default 128.
This, in turn, will create a problem where the chip's transmit pipe
will erroneously reuse an old command cell that is no longer valid.
The fix is to correctly initialize the chip's command cell upon setup.

[SCSI] bnx2i: Separated the hardware's cleanup procedure from ep_disconnect
This patch introduces a new bnx2i_hw_ep_disconnect routine which
contains all chip related disconnect and clean up procedure of
iSCSI offload connections. This separation is intended as a
preparation for the subsequent bnx2i_stop patch.

[SCSI] bnx2i: Bug fixes related to MTU change issue when there are active iscsi sessions
bnx2i driver has to wait and cleanup all iscsi endpoints before
returning from bnx2i_stop(). This is to make sure all chip resources
are freed before chip is reset.
As the requirements for 1G and 10G chipsets is different, added
per-device 'hba_shutdown_tmo' parameter to adapter structure
If the connections are not torn down by the daemon within this timeout
period, 'cid's will be leaked in 10G device. 1G devices are more
flexible and do not leak any resources because the whole chip ports
gets reset when MTU is changed or ethtool selftest is run
fixed a minor issue in bnx2i_ep_poll() which unnecessarily forced
error return code when driver timed out waiting for TCP connect
request to complete

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

[SCSI] bnx2i: use common iscsi suspend queue
This just has bnx2i use the iscsi_suspend_queue helper.
The suspend works as follows:
When ep_poll has succeeed iscsid will call conn_bind, the LLD will
then call iscsi_conn_bind which will clear the suspend bit.
When ep_disconnect is called (or if there is a conn error) we set
the suspend bit. For the ep_disconnect case I added a helper
in the previous kernel that will take the session lock to make sure
iscsi_queuecommand/xmit_task is not running and it will set
the suspend bit.

When bnx2i_adapter_ready() fails, connection handle(cid) = 0 is wrongly freed
because 'cid' is not yet allocated for the endpoint. Fix is to initialize
bnx2i_ep->ep_iscsi_cid to '-1' in bnx2i_alloc_ep() and not in
bnx2i_ep_connect() to avoid releasing invalid 'cid'. There is already a check
in bnx2i_free_iscsi_cid() not to free invalid iscsi connection handle (-1)

[SCSI] bnx2i : Fix command session number jump issue seen during cable pull test
Without the fix bnx2i would fail tt->xmit_task() when link is down and
libiscsi would have already incremented session->cmdsn before calling bnx2i's
xmit_task() entry point and will just return the command to SCSI-ML when
xmit_task() fails. libiscsi does not retract the session->cmdsn as the command
was never sent on wire. It is generally good idea for LLD, bnx2i to accept
the scsi cmnd/nopout and let upper layer timeout and go though normal session
recovery process. When link is down, unsolicited nopout will not be accepted
by bnx2i and connection will never enter recovery state. This fix is required
for MPIO to work corectly

[SCSI] bnx2i: register given device with cnic if shost != NULL in ep_connect()
When using iface, bnx2i was unable to offload further connections after all
active sessions are logged out. bnx2i will unregister the device from cnic
when the last connection is torn down. Next call to ep_connect() will fail
because the device is not registered. This issue is not seen if shost == NULL
is passed to ep_connect() call because in that case bnx2i will registers all
known devices with cnic before doing a route look-up. When shost != NULL,
bnx2i knows the device on which to offload the connection and has to register
this device before attempting to offload the connection
