2006-09-07[SCSI] aci94xx: implement link rate settingJames Bottomley
This patch implements the ability to set the minimum and maximum linkrates for both libsas (for expanders) and aic94xx (for the host phys). It also tidies up the setting of the hardware min and max to make sure they're updated when the expander emits a change broadcast. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-09-07[SCSI] scsi_transport_sas: make minimum and maximum linkrate settable quantitiesJames Bottomley

2006-09-07[SCSI] SAS: consolidate linkspeed definitionsJames Bottomley
At the moment we have two separate linkspeed enumerations covering roughly the same values.

Eventually I'll get around to removing the duplicated fields in asd_sas_phy and sas_phy ... Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-09-04[SCSI] FC transport: Add dev_loss_tmo callbacks, and new fast_io_fail_tmo w/ ↵James Smart
callback This patch adds the following functionality to the FC transport: - dev_loss_tmo LLDD callback : Called to essentially confirm the deletion of an rport. Thus, it is called whenever the dev_loss_tmo fires, or when the rport is deleted due to other circumstances (module unload, etc). It is expected that the callback will initiate the termination of any outstanding i/o on the rport. - fast_io_fail_tmo and LLD callback: There are some cases where it may take a long while to truly determine device loss, but the system is in a multipathing configuration that if the i/o was failed quickly (faster than dev_loss_tmo), it could be redirected to a different path and completed sooner.

2006-09-02[SCSI] SCSI and FC Transport: add netlink support for posting of transport ↵James Smart
events This patch formally adds support for the posting of FC events via netlink. It is a followup to the original RFC at: http://marc.theaimsgroup.com/?l=linux-scsi&m=114530667923464&w=2 and the initial posting at: http://marc.theaimsgroup.com/?l=linux-scsi&m=115507374832500&w=2 The patch has been updated to optimize the send path, per the discussions in the initial posting. Per discussions at the Storage Summit and at OLS, we are to use netlink for async events from transports. Also per discussions, to avoid a netlink protocol per transport, I've create a single NETLINK_SCSITRANSPORT protocol, which can then be used by all transports. This patch: - Creates new files scsi_netlink.c and scsi_netlink.h, which contains the single and shared definitions for the SCSI Transport. It is tied into the base SCSI subsystem intialization. Contains a single interface routine, scsi_send_transport_event(), for a transport to send an event (via multicast to a protocol specific group). - Creates a new scsi_netlink_fc.h file, which contains the FC netlink event messages - Adds 3 new routines to the fc transport: fc_get_event_number() - to get a FC event # fc_host_post_event() - to send a simple FC event (32 bits of data) fc_host_post_vendor_event() - to send a Vendor unique event, with arbitrary amounts of data. Note: the separation of event number allows for a LLD to send a standard event, followed by vendor-specific data for the event. Note: This patch assumes 2 prior fc transport patches have been installed: http://marc.theaimsgroup.com/?l=linux-scsi&m=115555807316329&w=2 http://marc.theaimsgroup.com/?l=linux-scsi&m=115581614930261&w=2 Sorry - next time I'll do something like making these individual patches of the same posting when I know they'll be posted closely together.

2006-09-02[SCSI] add refcouting around ctask usage in main IO patchMike Christie
It is possible that a ctask could be completing and getting cleaned up at the same time, we are finishing up the last data transfer. This could then result in the data transfer code using stale or invalid values. This patch adds a refcount to the ctask. When the count goes to zero then we know the transmit thread and recv thread or softirq are not touching it and we can safely release it. The eh should not need to grab a reference because it only cleans up a task if it has both the xmit mutex and recv lock (or recv side suspended).

2006-08-27[SCSI] scsi_transport_sas: remove local_attached flagJames Bottomley
This flag denotes local attachment of the phy. There are two problems with it: 1) It's actually redundant ... you can get the same information simply by seeing whether a host is the phys parent 2) we condition a lot of phy parameters on it on the false assumption that we can only control local phys. I'm wiring up phy resets in the aic94xx now, and it will be able to reset non-local phys as well. I fixed 2) by moving the local check into the reset and stats function of the mptsas, since that seems to be the only HBA that can't (currently) control non-local phys.

2006-07-28[SCSI] iscsi bugfixes: reduce memory allocationsMike Christie
We currently try to allocate a max_recv_data_segment_length which can be very large (default is 64K), and common uses are up to 1MB. It is very very difficult to allocte this much contiguous memory and it turns out we never even use it. We really only need a couple of pages, so this patch has us allocates just what we know what we need today. Later if vendors start adding vendor specific data and we need to handle large buffers we can do this, but for the last 4 years we have not seen anyone do this or request it.

2006-07-28[SCSI] iscsi bugfixes: fix oops when iser is flushing ioMike Christie
When we enter recovery and flush the running commands we cannot freee the connection before flushing the commands. Some commands may have a reference to the connection that needs to be released before. iscsi_stop was forcing the term and suspend too early and was causing a oops in iser, so this patch removes those callbacks all together and allows the LLD to handle that detail.

2006-07-28[SCSI] iscsi bugfixes: fix abort handlingMike Christie
Abort handler fixes. If a connection is dropped and reconnected while an abort is running then we should assume the recovery code will clean up the abort. Not doing so causes a oops. And if a command completes then we get the status for the abort, we do not need to call into the LLD to cleanup the resources. Doing this causes and oops in iser because it ends up freeing some resources twice. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-07-28[SCSI] iscsi bugfixes: fix r2t handlingMike Christie
The iscsi tcp code can pluck multiple rt2s from the tasks's r2tqueue in the xmit code. This can result in the task being queued on the xmit queue but gettting completed at the same time.

2006-07-09[SCSI] hide EH backup data outside the scsi_cmndChristoph Hellwig
Currently struct scsi_cmnd has various fields that are used to backup original data after the corresponding fields have been overridden for EH commands. This means drivers can easily get at it and misuse it. Due to the old_ naming this doesn't happen for most of them, but two that have different names have been used wrong a lot (see previous patch). Another downside is that they unessecarily bloat the scsi_cmnd size. This patch moves them onstack in scsi_send_eh_cmnd to fix those two issues aswell as allowing future EH fixes like moving the EH command submissions to use SG lists like everything else.

2006-07-09[SCSI] scsi_transport_sas: add unindexed portsJames Bottomley
Some SAS HBAs don't want to go to the trouble of tracking port numbers, so they'd simply like to say "add this port and give it a number". This is especially beneficial from the hotplug point of view, since tracking ports and the available number space can be a real pain. The current implementation uses an incrementing number per expander to add the port on. However, since there can never be more ports than there are phys, a later implementation will try to be more intelligent about this. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-06-29[SCSI] iscsi: add async notification of session eventsMike Christie
This patch adds or modifies the transport class functions used to notify userspace of session state events.

2006-06-29[SCSI] iscsi: pass target nr to session creationMike Christie
So the drivers do not use the channel numbers, but some do use the target numbers. We were just adding some goofy variable that just increases for the target nr. This is useless for software iscsi because it is always zero. And for qla4xxx the target nr is actually the index of the target/session in its FW or FLASH tables. We needed to expose this to userspace so apps could access those numbers so this patch just adds the target nr to the iscsi session creation functions. This way when qla4xxx's Hw thinks a session is at target nr 4 in its hw, it is exposed as that number in sysfs.

2006-06-29[SCSI] iscsi: break up session creation into two stagesMike Christie
qla4xxx is initialized in two steps like other HW drivers. It allocates the host, sets up the HW, then adds the host. For iscsi part of HW setup is setting up persistent iscsi sessions. At that time, the interupts are off and the driver is not completely set up so we just want to allocate them. We do not want to add them to sysfs and expose them to userspace because userspace could try to do lots of fun things with them like scanning and at that time the driver is not ready. So this patch breakes up the session creation like other functions that use the driver model in two the alloc and add parts. When the driver is ready, it can then add the sessions and userspace can begin using them. This also fixes a bug in the addition error patch where we forgot to do a get on the session.

2006-06-29[SCSI] iscsi: rm channel usage from iscsiMike Christie
I do not remember what I was thinking when we added the channel as a argument to the session create function. It was probably due to too much cut and paste work from the FC transport class. The channel is meaningless for iscsi drivers so this patch drops its usage everywhere in the iscsi related code.

2006-06-26[SCSI] sd/scsi_lib simplify sd_rw_intr and scsi_io_completionLuben Tuikov
This patch simplifies "good_bytes" computation in sd_rw_intr(). sd: "good_bytes" computation is always done in terms of the resolution of the device's medium, since after that it is the number of good bytes we pass around and other layers/contexts (as opposed ot sd) can translate that to their own resolution (block layer:512). It also makes scsi_io_completion() processing more straightforward, eliminating the 3rd argument to the function. It also fixes a couple of bugs like not checking return value, using "break" instead of "return;", etc. I've been running with this patch for some time now on a test (do-it-all) system.

If recovery failed or we are in recovery only overwrite the state if we are going to terminate the session or if we logged back in. STOP_CONN_SUSPEND and conn_cnt are not used. We only support a single connection session ATM, so cleanup that code while we are working around it.

2006-05-20[SCSI] iscsi: fix command requeues during iscsi recoveryMike Christie
Do not flush queues then block session. This will cause commands to needlessly swing around on us and remove goofy recovery_failed field and replace with state value. And do not start recovery from within the host reset function. This causeis too many problems becuase open-iscsi was desinged to call out to userspace then have userpscae decide if we should go into recovery or kill the session.
