target: Fix incorrect fallthrough of ALUA Standby/Offline/Transition CDBs

2013-04-11T08:48:49+00:00

This patch fixes a bug where a handful of informational / control CDBs
that should be allowed during ALUA access state Standby/Offline/Transition
where incorrectly returning CHECK_CONDITION + ASCQ_04H_ALUA_TG_PT_*.

This includes INQUIRY + REPORT_LUNS, which would end up preventing LUN
registration when LUN scanning occured during these ALUA access states.

target: writev() on single-element vector is pointless

2013-02-26T07:46:11+00:00

... in other news:
	filp_open() can't return a struct file with NULL dentry
	filp_open() can't return a struct file negative dentry
	filp_close() of something that never had been in any descriptor
tables is pointless - fput() is all you need

target: Use TCM_NO_SENSE for initialisation

2013-01-11T04:07:10+00:00

The compiler complained about uninitialized variables, so
use TCM_NO_SENSE here.

target: Fix incorrect inversion of TPGS_EXPLICT_ALUA check

2012-11-07T04:55:46+00:00

Fix a bug introduced with patch "target: pass sense_reason as a return value"
in for-3.8 code where only target port groups with TPGS_EXPLICT_ALUA set
need to be allowed to perform explictly ALUA.

target: pass sense_reason as a return value

2012-11-07T04:55:46+00:00

Pass the sense reason as an explicit return value from the I/O submission
path instead of storing it in struct se_cmd and using negative return
values.  This cleans up a lot of the code pathes, and with the sparse
annotations for the new sense_reason_t type allows for much better
error checking.

(nab: Convert spc_emulate_modesense + spc_emulate_modeselect to use
      sense_reason_t with Roland's MODE SELECT changes)

target: simplify alua support

2012-11-07T04:55:45+00:00

We always support ALUA for virtual backends, and never for physical ones.  Simplify
the code to just deal with these two cases and remove the superflous abstractions.

target: kill struct se_subsystem_dev

2012-11-07T04:55:43+00:00

Simplify the code a lot by killing the superflous struct se_subsystem_dev.
Instead se_device is allocated early on by the backend driver, which allocates
it as part of its own per-device structure, borrowing the scheme that is for
example used for inode allocation.

target: report too-small parameter lists everywhere

2012-09-07T18:09:08+00:00

Several places were not checking that the parameter list length
was large enough, and thus accessing invalid memory.  Zero-length
parameter lists are just a special case of this.
