* [SCSI] zfcp: Hold queue lock when checking port handle for ELS commandChristof Schmitt2008-01-11
| | | | | | | | | | | | We need to hold the queue-lock when checking whether we still have a valid port handle for the ELS command, i.e whether we can issue this request for this port. If the error recovery is about to close this port, then it competes for the queue-lock. If the close request issued by the error recovery wins, then it is guaranteed that this port has been blocked for other requests.

* [SCSI] zfcp: Fix evaluation of port handles in abort handlerChristof Schmitt2008-01-11
| | | | | | | | | | | According to the FSF spec, word 0 (bytes 0-3) has the handle specified with the abort command and word 1 (bytes 4-7) has the handle for the command to be aborted.

* [SCSI] zfcp: fix use after free bug.Heiko Carstens2008-01-11
| | | | | | | | | | | | | | | | | zfcp_erp_strategy_check_fsfreq() checks if it is safe to access the fsf_req associated with the erp_action that gets passed. To test if it is safe it accesses the fsf_req in order to get its index into the hash list. This is broken since the fsf_req might be freed already and the read index has no meaning. It could lead to memory corruption. Fix this by introducing a new zfcp_reqlist_find_safe() method which just checks if addresses are equal. This is slower, but only gets called in case of error recovery.

| | | | | | | | | | | | | | | | | | we are planning a major rewrite of the zfcp driver, meaning that a lot of patches will hit the mailing-list in the near future. Since I can't support this additional work-load along with my other responsibilities we are shifting the maintainership to Christof Schmitt as the maintainer and Martin Peschke as the co-maintainer.

If it does we do not really know what is coming down after the header, unless we evaluate the hdr and do some guessing sometimes.

* [SCSI] libiscsi: fix nop handlingMike Christie2008-01-11
| | | | | | | | | | | | During root boot and shutdown the target could send us nops. At this time iscsid cannot be running, so the target will drop the session and the boot or shutdown will hang.

* [SCSI] libiscsi: fix shutdownMike Christie2008-01-11
| | | | | | | | | | | | | 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] libiscsi: grab eh_mutex during host resetMike Christie2008-01-11
| | | | | | | | | | | | | | I thought we may not need the eh mutex during host reset, but that is wrong with the new shutdown code. When start_session_recovery sets the state to terminate then drops the session lock. The scsi eh thread could then grab the session lock see that we are terminating and then return failed to scsi-ml. scsi-ml's eh then owns the command and will do whatever it wants with it. But then the iscsi eh thread could grab the session lock and want to complete the scsi commands that we in the LLD, but it no longer owns them and kaboom.

* [SCSI] libiscsi, iscsi_tcp: iscsi pool cleanupOlaf Kirch2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | iscsi_pool_init simplified iscsi_pool_init currently has a lot of duplicate kfree() calls it does when some allocation fails. This patch simplifies the code a little by using iscsi_pool_free to tear down the pool in case of an error. iscsi_pool_init also returns a copy of the item array to the caller. Not all callers use this array, so we make it optional. Instead of allocating a second array and return that, allocate just one array, of twice the size. Update users of iscsi_pool_{init,free} This patch drops the (now useless) second argument to iscsi_pool_free, and updates all callers. It also removes the ctask->r2ts array, which was never used anyway. Since the items argument to iscsi_pool_init is now optional, we can pass NULL instead.

* [SCSI] libiscsi,iser: patch for AHS supportBoaz Harrosh2008-01-11
| | | | | | | | | | | | | | - The default initialization of hdr_max is the minimum - sizeof(struct iscsi_cmd) - Once this patch goes into iser the default initialization at libiscsi can be removed. - This is not yet full support for AHSs at iser end. But it should be easy. Just allocate more space at iser_desc right after iscsi_hdr. Than at transmission time use ctask->hdr_len to retrieve the total size of all iscsi pdu headers.

* [SCSI] iscsi_tcp, libiscsi: initial AHS SupportBoaz Harrosh2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] aacraid: fix driver failure with Dell PowerEdge Expandable RAID ↵Salyzyn, Mark2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Controller 3/Di As reported in http://bugzilla.kernel.org/show_bug.cgi?id=3D9133 it was discovered that the PERC line of controllers lacked a key 64 bit ScatterGather capable SCSI pass-through function. The adapters are still capable of 64 bit ScatterGather I/O commands, but these two can not be mixed. This problem was exacerbated by the introduction of the SCSI Generic access to the DASD physical devices. The fix for users before this patch is applied is aacraid.dacmode=3D0 on the kernel command line to disable 64 bit I/O. The enclosed patch introduces a new adapter quirk and tries to limp along by enabling pass-through in situations where memory is 32 bit addressable on 64 bit machines, or disable the pass-through functions altogether. I expect that the check for 32 bit addressable memory to be controversial in that it can be incorrect in non-Dell non-Intel systems that PERC would never be installed under, the alternative is to disable pass-through in all cases which could be reported as another regression. Pass-through is used for SCSI Generic access to the physical devices, or for the management applications to properly function. In systems where this patch has disabled pass-through because it is unsupportable in combination with I/O performance, the user can choose to enable pass-through by turning off dacmode (aacraid.dacmode=3D0) or limiting the discovered kernel memory (mem=3D4G) with an associated loss in runtime performance. If we chose instead to turn off 64 bit dacmode for the adapters with this quirk, then this would be reported as another regression.

* [SCSI] sd,sr: add early detection of medium not presentJames Bottomley2008-01-11
| | | | | | | | | The current scsi_test_unit_ready() is updated to return sense code information (in struct scsi_sense_hdr). The sd and sr drivers are changed to interpret the sense code return asc 0x3a as no media and adjust the device status accordingly.

I will deal > with the warnings ... Actually there are a lot of endianess warnings, fortunately most of them harmless. The patch below fixes all of them up (including the ones in the patch I replied to), except for aac_init_adapter which is really odd and I don't know what to do.
