* linux: drop __bitwise__ everywhereMichael S. Tsirkin2016-12-151-1/+1
| | | | | | | | | | | | | __bitwise__ used to mean "yes, please enable sparse checks unconditionally", but now that we dropped __CHECK_ENDIAN__ __bitwise is exactly the same. There aren't many users, replace it by __bitwise everywhere. Signed-off-by: Michael S.

* iscsi: Add Serial Number Arithmetic LT and GT into iscsi_proto.hNicholas Bellinger2011-07-251-0/+30
| | | | | | | | | | | | | | | This patch moves the iscsi_sna_lt() and iscsi_sna_lte(), along with iscsi_sna_gt() and iscsi_sna_gte() from iscsi_target_mod into static inlines inside of include/scsi/iscsi_proto.h This patch also includes the ISCSI_HDR_LEN and ISCSI_CRC_LEN definitions.

* iscsi: Use struct scsi_lun in iscsi structs instead of u8[8]Andy Grover2011-07-251-9/+9
| | | | | | | | | | struct scsi_lun is also just a struct with an array of 8 octets (64 bits) but using it instead in iscsi structs lets us call scsilun_to_int without a cast, and also lets us copy it using assignment, instead of memcpy().

* iscsi: Resolve iscsi_proto.h naming conflicts with drivers/target/iscsiNicholas Bellinger2011-07-251-8/+22
| | | | | | | | | | | | | | | | | | | | 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] libiscsi: Check TMF state before sending PDUMike Christie2009-12-041-0/+2
| | | | | | | | | | | | | | | | | | Patch and mail from both MikeC and HannesR: Before we're trying to send a PDU we have to check whether a TMF is active. If so and if the PDU will be affected by the TMF we should allow only Data-out PDUs to be sent. If fast_abort is set, no Data-out PDUs will be sent while a LUN reset is being processed for a affected LUN. fast_abort is now ingored during a ABORT TASK tmf. We will not send any Data-outs for a task if the task is being aborted.

* [SCSI] libiscsi: fix session age rollover and remove cid encodingMike Christie2008-02-081-2/+2
| | | | | | | | | | | | The session age mask is only 4 bits, but session->age is 32. When it gets larger then 15 and we try to or the bits some bits get dropped and the check for session age in iscsi_verify_itt is useless. The ISCSI_CID_MASK related bits are also useless since cid is always one. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] libiscsi: fix shutdownMike Christie2008-01-121-0/+2
| | | | | | | | | | | | | We were using the device delete sysfs file to remove each device then logout. Now in 2.6.21 this will not work because the sysfs delete file returns immediately and does not wait for the device removal to complete. This causes a hang if a cache sync is needed during shutdown. Before .21, that approach had other problems, so this patch fixes the shutdown code so that we remove the target and unbind the session before logging out and shut down the session Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] iscsi_tcp, libiscsi: initial AHS SupportBoaz Harrosh2008-01-121-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | at libiscsi generic code - currently code assumes a storage space of pdu header is allocated at llds ctask and is pointed to by iscsi_cmd_task->hdr. Here I add a hdr_max field pertaining to that storage, and an hdr_len that accumulates the current use of the pdu-header. - Add an iscsi_next_hdr() inline which returns the next free space to write new Header at. Also iscsi_next_hdr() is used to retrieve the address at which to write the header-digest. - Add iscsi_add_hdr(length). What the user do is calls iscsi_next_hdr() for address of the new header, than calls iscsi_add_hdr(length) with the size of the new header. iscsi_add_hdr() will check if space is available and update to the new size. length must be padded according to standard. - Add 2 padding inline helpers thanks to Olaf. Current patch does not use them but Following patches will. Also moved definition of ISCSI_PAD_LEN to iscsi_proto.h which had PAD_WORD_LEN that was never used anywhere. - Let iscsi_prep_scsi_cmd_pdu() signal an Error return since now it is possible that it will fail. - I was tired of yet again writing a "this is a digest" comment next to sizeof(__u32) so I defined a new ISCSI_DIGEST_SIZE. Now I don't need any comments. Changed all places that used sizeof(__u32) or "4" in connection to a digest. iscsi_tcp specific code - At struct iscsi_tcp_cmd_task allocate maximum space allowed in standard for all headers following the iscsi_cmd header. and mark it so in iscsi_tcp_session_create() - At iscsi_send_cmd_hdr() retrieve the correct headers size and write header digest at iscsi_next_hdr().

* [SCSI] libiscsi, iscsi_tcp: add device supportMike Christie2008-01-121-0/+2
| | | | | | | | | | | This patch adds logical unit reset support. This should work for ib_iser, but I have not finished testing that driver so it is not hooked in yet. This patch also temporarily reverts the iscsi_tcp r2t write out patch. That code is completely rewritten in this patchset.
