• f8e471f9e   target: Add target_show_dynamic_sessions attribute helper ... Browse Code »

  This patch adds a new helper function that can be used by fabric driver
  TPG attributes for dumping the list of active sessions with a dynamically
  generated se_node_acl. (generate_node_acl=1).

  It prints one se_node_acl->initiatorname per line, up to PAGE_SIZE which
  is due to the current limitiation of single page attribute output within
  sysfs and configfs code.

  Note that if a session is referencing a explicit NodeACL, the InitiatorName
  will not appear within dynamic_sessions output.

• c66ac9db8   [SCSI] target: Add LIO target core v4.0.0-rc6 ... Browse Code »

  LIO target is a full featured in-kernel target framework with the
  following feature set:

  High-performance, non-blocking, multithreaded architecture with SIMD
  support.

  Advanced SCSI feature set:

  * Persistent Reservations (PRs)
  * Asymmetric Logical Unit Assignment (ALUA)
  * Protocol and intra-nexus multiplexing, load-balancing and failover (MC/S)
  * Full Error Recovery (ERL=0,1,2)
  * Active/active task migration and session continuation (ERL=2)
  * Thin LUN provisioning (UNMAP and WRITE_SAMExx)

  Multiprotocol target plugins

  Storage media independence:

  * Virtualization of all storage media; transparent mapping of IO to LUNs
  * No hard limits on number of LUNs per Target; maximum LUN size ~750 TB
  * Backstores: SATA, SAS, SCSI, BluRay, DVD, FLASH, USB, ramdisk, etc.

  Standards compliance:

  * Full compliance with IETF (RFC 3720)
  * Full implementation of SPC-4 PRs and ALUA

  Significant code cleanups done by Christoph Hellwig.

  [jejb: fix up for new block bdev exclusive interface. Minor fixes from
  Randy Dunlap and Dan Carpenter.]
