| * [SCSI] Fix refcount breakage with 'echo "1" > scan' when target already presentJames Bottomley2006-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Spotted by: Dan Aloni <da-xx@monatomic.org> The problem is there's inconsistent locking semantic usage of scsi_alloc_target(). Two callers assume the target comes back with reference unincremented and the third assumes its incremented. Fix by always making the reference incremented on return. Also fix path in target alloc that could consistently increment the parent lock. Finally document scsi_alloc_target() so its callers know what the expectations are.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] SCSI and FC Transport: add netlink support for posting of transport ↵James Smart2006-09-02

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.

| * [SCSI] scsi_tcp: rm data rx and tx tfmsMike Christie2006-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently allocated seperate tfms for data and header digests. There is no reason for this since we can never calculate a rx header and digest at the same time. Same for sends. So this patch removes the data tfms and has the send and recv sides use the rx_tfm or tx_tfm. I also made the connection creation code preallocate the tfms because I thought I hit a bug where I changed the digests settings during a relogin but could not allocate the tfm and then we just failed.

| * [SCSI] iscsi_tcp: fix padding, data digests, and IO at weird offsetsMike Christie2006-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iscsi_tcp calculates padding by using the expected transfer length. This has the problem where if we have immediate data = no and initial R2T = yes, and the transfer length ended up needing padding then we send: 1. header 2. padding which should have gone after data 3. data Besides this bug, we also assume the target will always ask for nice transfer lengths and the first burst length will always be a nice value. As far as I can tell form the RFC this is not a requirement. It would be silly to do this, but if someone did it we will end doing bad things. Finally the last bug in that bit of code is in our handling of the recalculation of data digests when we do not send a whole iscsi_buf in one try. The bug here is that we call crypto_digest_final on a iscsi_sendpage error, then when we send the rest of the iscsi_buf, we doiscsi_data_digest_init and this causes the previous data digest to be lost. And to make matters worse, some of these bugs are replicated over and over and over again for immediate data, solicited data and unsolicited data. So the attached patch made over the iscsi git tree (see kernel.org/git for details) which I updated today to include the patches I said I merged, consolidates the sending of data, padding and digests and calculation of data digests and fixes the above bugs.

| * [SCSI] attempt to complete r2t with data len greater than max burstMike Christie2006-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A couple targets like string bean and MDS, send r2ts with a data len greater than the max burst we agreed to. We were being strict in our enforcing of the iscsi rfc in that code path, but there is no driver limitation that prevents us from fullfilling the request. To allow those targets to work we will ignore the max_burst length and send as much data as the target asks for assuming it has consciously decided to override its max burst length.

| * [SCSI] add refcouting around ctask usage in main IO patchMike Christie2006-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

Since the standard disallows such characters, this will affect only non-compliant devices. To help maintain backward compatibility, NUL characters are treated specially. They are taken as string terminators; they and all the following characters are set to ' '. If some valid characters get erased as a result... well, we weren't seeing them before so we haven't lost anything. The primary purpose of this change is to allow blacklist entries to match devices with illegal Vendor or Product strings. In addition, the patch updates a couple of function prototypes, giving inq_result its correct type (unsigned char *).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch sets can_queue in the aic94xx driver's scsi_host to better performing values than what's there currently. It seems that asd_ha->seq.can_queue reflects the number of requests that can be queued per controller; so long as there's one scsi_host per controller, it seems logical that the scsi_host ought to have the same can_queue value. To the best of my (still limited) knowledge, this method provides the correct value. The effect of leaving this value set to 1 is terrible performance in the case of either (a) certain Maxtor SAS drives flying solo or (b) flooding several disks with I/O simultaneously (md-raid). There may be more scenarios where we see similar problems that I haven't uncovered. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] scsi_transport_sas: remove local_attached flagJames Bottomley2006-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | [SCSI] fc transport: add fc_host system_hostname attribute and u64_to_wwn()James Smart2006-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the fc transport for the following: - Addition of a new attribute "system_hostname" which can be used to set the fully qualified hostname that the fc_host is attached to. The fc_host can then register this string as the FDMI-based host name attribute. Note: for NPIV, a fc_host could be associated with a system which is not the local system. - Add the inline function u64_to_wwn(), which is the inverse of the existing wwn_to_u64() function. - Slight reorg, just to keep dynamic attributes with each other, etc Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
