      iscsi: Resolve iscsi_proto.h naming conflicts with drivers/target/iscsi · 12352183
      Nicholas Bellinger 提交于
      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.

      RDMA/cma: Pass QP type into rdma_create_id() · b26f9b99
      Sean Hefty 提交于
      The RDMA CM currently infers the QP type from the port space selected
      by the user.  In the future (eg with RDMA_PS_IB or XRC), there may not
      be a 1-1 correspondence between port space and QP type.  For netlink
      export of RDMA CM state, we want to export the QP type to userspace,
      so it is cleaner to explicitly associate a QP type to an ID.
      
      Modify rdma_create_id() to allow the user to specify the QP type, and
      use it to make our selections of datagram versus connected mode.

      IB/iser: Fix error flow in iser_create_ib_conn_res() · 9fda1ac5
      Dan Carpenter 提交于
      We shouldn't free things here because we free them later.
      The call tree looks like this:
      	iser_connect() ==> initiating the connection establishment
      and later
      	iser_cma_handler() => iser_route_handler() => iser_create_ib_conn_res()
      if we fail here, eventually iser_conn_release() is called, resulting
      in a double free.

      IB/iser: Enhance disconnection logic for multi-pathing · 39ff05db
      Or Gerlitz 提交于
      The iser connection teardown flow isn't over until the underlying
      Connection Manager (e.g the IB CM) delivers a disconnected or timeout
      event through the RDMA-CM.  When the remote (target) side isn't
      reachable, e.g when some HW e.g port/hca/switch isn't functioning or
      taken down administratively, the CM timeout flow is used and the event
      may be generated only after relatively long time -- on the order of
      tens of seconds.
      
      The current iser code exposes this possibly long delay to higher
      layers, specifically to the iscsid daemon and iscsi kernel stack. As a
      result, the iscsi stack doesn't respond well: this low-level CM delay
      is added to the fail-over time under HA schemes such as the one
      provided by DM multipath through the multipathd(8) service.
      
      This patch enhances the reference counting scheme on iser's IB
      connections so that the disconnect flow initiated by iscsid from user
      space (ep_disconnect) doesn't wait for the CM to deliver the
      disconnect/timeout event.  (The connection teardown isn't done from
      iser's view point until the event is delivered)
      
      The iser ib (rdma) connection object is destroyed when its reference
      count reaches zero.  When this happens on the RDMA-CM callback
      context, extra care is taken so that the RDMA-CM does the actual
      destroying of the associated ID, since doing it in the callback is
      prohibited.
      
      The reference count of iser ib connection normally reaches three,
      where the <ref, deref> relations are
      
       1. conn <init, terminate>
       2. conn <bind, stop/destroy>
       3. cma id <create, disconnect/error/timeout callbacks>
      
      With this patch, multipath fail-over time is about 30 seconds, while
      without this patch, multipath fail-over time is about 130 seconds.

      IB/iser: Remove buggy back-pointer setting · d265b980
      Or Gerlitz 提交于
      The iscsi connection object life cycle includes binding and unbinding
      (conn_stop) to/from the iscsi transport connection object.  Since
      iscsi connection objects are recycled, at the time the transport
      connection (e.g iser's IB connection) is released, it is not valid to
      touch the iscsi connection tied to the transport back-pointer since it
      may already point to a different transport connection.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      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.

      If a task did not complete normally due to a TMF, libiscsi will
      now complete the task with the state ISCSI_TASK_ABRT_TMF. Drivers
      like bnx2i that need to free resources if a command did not complete normally
      can then check the task state. If a driver does not need to send
      a special command if we have dropped the session then they can check
      for ISCSI_TASK_ABRT_SESS_RECOV.

      [SCSI] iscsi: pass ep connect shost · 10eb0f01
      Mike Christie 提交于
      When we create the tcp/ip connection by calling ep_connect, we currently
      just go by the routing table info.
      
      I think there are two problems with this.
      
      1. Some drivers do not have access to a routing table. Some drivers like
      qla4xxx do not even know about other ports.
      
      2. If you have two initiator ports on the same subnet, the user may have
      set things up so that session1 was supposed to be run through port1. and
      session2 was supposed to be run through port2. It looks like we could
      end with both sessions going through one of the ports.
