• add3508a0c Changes: - Fixed race condition between SCST session registration and IB channel event handler in srpt_add_one(): at least in theory it was possible that sdev->scst_tgt was accessed before being initialized properly. - A kernel WARN_ON() is no longer triggered when a DREQ has been received after SCST session deregistration started. - Made sure that srpt_unmap_sg_to_ib_sge() does not call ib_dma_unmap_sg() twice. - Moved srpt_unmap_sg_to_ib_sge() call out of srpt_reset_ioctx() and srpt_abort_scst_cmd() into the callers of these functions. - Renamed some of the SRPT command states.

• 23accb2e12 When converting the SCST source code into a series of upstream patches, SCST is built via the kbuild infastructure. In kernel version 2.6.24 (commit f77bf01425b11947eeb3b5b54685212c302741b8) the kbuild variable ccflags-y has been introduced and the use of EXTRA_CFLAGS in kbuild makefiles has been deprecated. The patch below converts SCST's in-tree makefiles such that these use ccflags-y instead of EXTRA_CFLAGS when generating kernel patches for kernel 2.6.24 or later. Vladislav Bolkhovitin 2010-01-11 19:16:38 +00:00
• b85002b263 Made sure that if a work completion reports an error status that completion queue processing is not aborted but that the remaining completion queue entries are processed. Bart Van Assche 2010-01-11 19:00:03 +00:00

• 0cd53b65ef Made sure that the pre-cflags patches are uniform to the other in-tree kernel patches, i.e. that -p1 has to be used to apply these patches. Bart Van Assche 2010-01-10 13:16:28 +00:00
• 048a338747 Backported some 2.6.32 IB bug fixes to the 2.6.30 kernel. Bart Van Assche 2010-01-10 13:14:28 +00:00
• 5cc522712e Fixed the following race conditions: - With thread=1, the kernel thread was stopped before all I/O was stopped. This could result in IB completions for responses sent to the initiator not being processed, scst_tgt_cmd_done() not being called for certain SCST commands and hence this race could cause "rmmod ib_srpt" to hang. - ib_unregister_event_handler() was called after cancel_work_sync(). This could cause srpt_event_handler() to queue new work, work that could be executed after the data it operates on had been deallocated. Change: simplified module unloading by calling ib_destroy_cm_id(sdev->cm_id) before calling scst_unregister(). This made the variable "cleaning_up" superfluous. Bart Van Assche 2010-01-09 20:14:13 +00:00
• 1660fe1c3c Fixed the following category of checkpatch complaints: 2 ERROR: code indent should use tabs where possible Bart Van Assche 2010-01-09 15:01:59 +00:00

• 3ec2a5c02c Updated kernel revisions. Bart Van Assche 2010-01-07 12:41:46 +00:00
• 7bf99a3584 Removed some TRACE_ENTRY() / TRACE_EXIT() statements. Bart Van Assche 2010-01-06 20:47:08 +00:00
• 754d139673 Fixed checkpatch complaints about whitespace (use tabs instead of spaces / trailing whitespace) and the sparse complaint about using '0' as a pointer. Bart Van Assche 2010-01-06 20:22:15 +00:00
• ca9004962d Changes: - srpt_release_channel_by_cmid(): the sdev->spinlock and scst_mgmt_lock are no longer locked nested. - srpt_find_channel(): does now return NULL when the channel is not found (which never happens). Bart Van Assche 2010-01-06 20:11:24 +00:00
• 05d1bbfedc A huge chunk of related to each other changes, which had to be tested together. Vladislav Bolkhovitin 2010-01-06 13:02:22 +00:00
• 6a523b3c13 Added more debugging code. Bart Van Assche 2010-01-04 20:56:00 +00:00
• 45c93135f8 Changes: - Removed references to SCST core internal state names. - Does no longer accept new connections while unloading. - Module unloading should now really no longer cause a hang. Bart Van Assche 2010-01-04 20:26:19 +00:00
• af086e27a8 Merged two lines. Bart Van Assche 2010-01-04 20:13:04 +00:00
• af5ae6eeb7 Do not try to include files marked for deletion. Bart Van Assche 2010-01-04 20:05:53 +00:00
• 388c38bfd9 Fixed typos. Bart Van Assche 2010-01-03 08:34:21 +00:00
• a8a72c1b51 Fixed sporadic lockup triggered by removing the ib_srpt kernel module. The following complaint was logged by the kernel when this happened: Bart Van Assche 2010-01-02 13:56:12 +00:00
• d124f1cc8e Changes: - Decreased number of target-to-initiator request send buffers from two to one such that a clear error message can be printed when the SRP initiator did not respond to the SRP_CRED_REQ information unit. - Bug fix: don't modify ch->last_response_req_lim when sending an SRP information unit that contains the REQUEST LIMIT DELTA field failed. Bart Van Assche 2010-01-02 12:27:32 +00:00
• e1de778c3a Changes related to credit-based SRP buffer management: - Bug fix: don't set the REQUEST LIMIT DELTA field to SRPT_RQ_SIZE when sending the first reponse to the initiator but to the proper value (a small integer). - An SRP_CRED_REQ information unit is now sent to the initiator if the number of I/O contexts available for receiving dropped below two I/O contexts (see also the SRP standard for more information). This change is required to fix the SRP initiator lockup that happens when the initiator sends requests faster than the target can process them. In order to fix the lockup, it is also necessary to implement SRP_CRED_REQ support in the SRP initiator in the vanilla Linux kernel and in OFED. Neither kernel version 2.6.32 nor OFED 1.5 nor any previous version of these components supports SRP_CRED_REQ information units. See also http://bugzilla.kernel.org/show_bug.cgi?id=14235 for more information about the initiator lockup. Bart Van Assche 2010-01-01 17:48:07 +00:00
• 0d4ba05ae8 Added and commented out the following statement: EXTRA_CFLAGS += -DCONFIG_SCST_EXTRACHECKS Bart Van Assche 2010-01-01 17:06:38 +00:00
• ad4cde8bfe The patch below fixes the following two issues in the iscsi-scst-howto.txt document: * For some Linux distro's the command iscsi-iname is installed in /usr/sbin and for others in /sbin. * The scst and scst_vdisk modules must be loaded before the sample scstadmin commands work. Vladislav Bolkhovitin 2009-12-28 19:58:39 +00:00
• bab121a720 Compilation of the SCST's sysfs code triggers a section mismatch because the function scst_sysfs_cleanup() is declared as an exit-only function while it is also called from init_scst(). The patch below fixes this section mismatch. Vladislav Bolkhovitin 2009-12-28 19:55:45 +00:00
• d1e5f40622 Changes: - Convert sense data to/from fixed format / descriptor format before sending back a response. - Print an error message to the kernel log when an unsupported IB event has been received. - Return the SCSI status BUSY instead of CHECK CONDITION when allocating an SCST command failed (until r1409, the SCSI status in the SRP_RSP information unit was set to TASK SET FULL in this case).

• 8d13d15332 Follow-up for r1415: compiles again without warnings on both 32-bit and 64-bit systems. Bart Van Assche 2009-12-26 18:57:17 +00:00

• 2fbe389419 Behavior changes: - Fixed: the SCSOLNT and UCSOLNT bits were ignored in received SRP requests, and the SOLNT bit was not set in responses when required. This is required by the SRP protocol specification. - Fixed: SRP_RSP messages must be limited to the MAXIMUM TARGET TO INITIATOR IU LENGTH field indicated in the SRP_LOGIN_RSP response instead of the maximum message size supported by SRPT. This is also required by the SRP protocol specification. - Fixed: the STATUS field of response messages with status GOOD and that contain sense data is no longer modified into CHECK CONDITION. Internal changes (refactoring): - Replaced the SCSI sense data handling data structures and code in SRPT by those of the SCST core. - Moved the code for building an error response from srpt_handle_cmd() and srpt_handle_tsk_mgmt() to srpt_handle_new_iu(). - Removed the ioctx::data_len member.

• 0075ec260e Limiting MaxOutstandingR2T to 1, because this code is known to crash sometimes. The proper fix is too big for the stable branch. Vladislav Bolkhovitin 2009-12-24 19:33:16 +00:00
