target: Fix lookup of dynamic NodeACLs during cached demo-mode operation

2013-03-06T03:24:03Z

commit fcf29481fb8e106daad6688f2e898226ee928992 upstream. This patch fixes a bug in core_tpg_check_initiator_node_acl() -> core_tpg_get_initiator_node_acl() where a dynamically created se_node_acl generated during session login would be skipped during subsequent lookup due to the '!acl->dynamic_node_acl' check, causing a new se_node_acl to be created with a duplicate ->initiatorname. This would occur when a fabric endpoint was configured with TFO->tpg_check_demo_mode()=1 + TPF->tpg_check_demo_mode_cache()=1 preventing the release of an existing se_node_acl during se_session shutdown. Also, drop the unnecessary usage of core_tpg_get_initiator_node_acl() within core_dev_init_initiator_node_lun_acl() that originally required the extra '!acl->dynamic_node_acl' check, and just pass the configfs provided se_node_acl pointer instead.

target: Add generation of LOGICAL BLOCK ADDRESS OUT OF RANGE

2012-08-02T13:37:48Z

commit e2397c704429025bc6b331a970f699e52f34283e upstream. Many SCSI commands are defined to return a CHECK CONDITION / ILLEGAL REQUEST with ASC set to LOGICAL BLOCK ADDRESS OUT OF RANGE if the initiator sends a command that accesses a too-big LBA. Add an enum value and case entries so that target code can return this status. Signed-off-by: Roland Dreier Signed-off-by: Nicholas Bellinger Signed-off-by: Ben Hutchings

target: Allow control CDBs with data > 1 page

2012-03-01T00:31:09Z

commit 4949314c7283ea4f9ade182ca599583b89f7edd6 upstream. We need to handle >1 page control cdbs, so extend the code to do a vmap if bigger than 1 page. It seems like kmap() is still preferable if just a page, fewer TLB shootdowns(?), so keep using that when possible. Rename function pair for their new scope.

target: Set additional sense length field in sense data

2012-01-26T00:13:50Z

commit 895f3022523361e9b383cf48f51feb1f7d5e7e53 upstream. The target code was not setting the additional sense length field in the sense data it returned, which meant that at least the Linux stack ignored the ASC/ASCQ fields. For example, without this patch, on a tcm_loop device: # sg_raw -v /dev/sda 2 0 0 0 0 0 gives cdb to send: 02 00 00 00 00 00 SCSI Status: Check Condition Sense Information: Fixed format, current; Sense key: Illegal Request Raw sense data (in hex): 70 00 05 00 00 00 00 00 while after the patch we correctly get the following (which matches what a regular disk returns): cdb to send: 02 00 00 00 00 00 SCSI Status: Check Condition Sense Information: Fixed format, current; Sense key: Illegal Request Additional sense: Invalid command operation code Raw sense data (in hex): 70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 Signed-off-by: Roland Dreier Signed-off-by: Nicholas Bellinger Signed-off-by: Greg Kroah-Hartman
