These callbacks tend to use fc_block_scsi_eh() requiring scsi_cmnd. In order to start decoupling above eh callbacks from scsi_cmnd, introduce a new variant of the function called fc_block_rport() taking an fc_rport as argument.

Other FCP LLDDs such as qla2xxx and lpfc shield their queuecommand() to only access any of scsi_prot_sg...() if (scsi_get_prot_op(cmd) != SCSI_PROT_NORMAL). Do the same thing for zfcp, which introduced DIX support with commit ef3eb71d8ba4 ("[SCSI] zfcp: Introduce experimental support for DIF/DIX"). Otherwise, TUR SCSI commands as part of scsi_eh likely fail in zfcp, because the regular SCSI command with DIX protection data, that scsi_eh re-uses in scsi_send_eh_cmnd(), of course still has (scsi_prot_sg_count() != 0) and so zfcp sends down bogus requests to the FCP channel hardware. This causes scsi_eh_test_devices() to have (finish_cmds == 0) [not SCSI device is online or not scsi_eh_tur() failed] so regular SCSI commands, that caused / were affected by scsi_eh, are moved to work_q and scsi_eh_test_devices() itself returns false. In turn, it unnecessarily escalates in our case in scsi_eh_ready_devs() beyond host reset to finally scsi_eh_offline_sdevs() which sets affected SCSI devices offline with the following kernel message: "kernel: sd H:0:T:L: Device offlined - not ready after error recovery" Signed-off-by: Steffen Maier Fixes: ef3eb71d8ba4 ("[SCSI] zfcp: Introduce experimental support for DIF/DIX") Cc: #2.6.36+ Reviewed-by: Benjamin Block Signed-off-by: Benjamin Block Signed-off-by: Martin K.

When this flag is set, it is possible, in regards to the FCP standard, that the storage-server processes the command normally, up to the point where data is missing and simply ignores those. In this case no CHECK CONDITION would be set, and because we ignored the FCP_RESID_OVER flag we resulted in at least a data loss or even -corruption as a follow-up error, depending on how the applications/layers on top behave. To prevent this, we now set the host-byte of the corresponding scsi_cmnd to DID_ERROR. Other storage-behaviors, where the same condition results in a CHECK CONDITION set in the answer, don't need to be changed as they are handled in the mid-layer already.

While it already saves space by not dumping any empty residual entries of the large successful GPN_FT response (4 pages), there are seldom cases where the GPN_FT response is unsuccessful and likely does not have FC_NS_FID_LAST set in fp_flags so we did not cap the trace record. We typically see such case for an initiator WWPN, which is not in any zone. Cap unsuccessful responses to at least the actual basic CT_IU response plus whatever fits the SAN trace record built-in "payload" buffer just in case there's trailing information of which we would at least see the existence and its beginning. In order not to erroneously cap successful responses, we need to swap calling the trace function and setting the CT / ELS status to success (0).

That way we would also get the full FCP_SNS_INFO in case a target would ever send more than min(SCSI_SENSE_BUFFERSIZE==96, ZFCP_DBF_PAY_MAX_REC==256)==96. The mandatory part of FCP_RSP IU is only 24 bytes. PAYload costs at least one full PAY record of 256 bytes anyway. We cap to the hardware response size which is only FSF_FCP_RSP_SIZE==128. So we can just put the whole FCP_RSP IU with any optional parts into PAYload similarly as we do for SAN PAY since v4.9 commit aceeffbb59bb ("zfcp: trace full payload of all SAN records (req,resp,iels)"). This does not cause any additional trace records wasting memory. Decoded trace records were confusing because they showed a hard-coded sense data length of 96 even if the FCP_RSP_IU field FCP_SNS_LEN showed actually less. Since the same commit, we set pl_len for SAN traces to the full length of a request/response even if we cap the corresponding trace. In contrast, here for SCSI traces we set pl_len to the pre-computed length of FCP_RSP IU considering SNS_LEN or RSP_LEN if valid. Nonetheless we trace a hardcoded payload of length FSF_FCP_RSP_SIZE==128 if there were optional parts. This makes it easier for the zfcpdbf tool to format only the relevant part of the long FCP_RSP UI buffer. And any trailing information is still available in the payload trace record just in case. Rename the payload record tag from "fcp_sns" to "fcp_riu" to make the new content explicit to zfcpdbf which can then pick a suitable field name such as "FCP rsp IU all:" instead of "Sense info :" Also, the same zfcpdbf can still be backwards compatible with "fcp_sns".

However, this is only one of multiple possible sources determining a failed struct zfcp_fsf_req. An FSF request can also "fail" if its response runs into an ERP timeout or if it gets dismissed because a higher level recovery was triggered [trace tags "erscf_1" or "erscf_2" in zfcp_erp_strategy_check_fsfreq()]. FSF requests with ERP timeout are: FSF_QTCB_EXCHANGE_CONFIG_DATA, FSF_QTCB_EXCHANGE_PORT_DATA, FSF_QTCB_OPEN_PORT_WITH_DID or FSF_QTCB_CLOSE_PORT or FSF_QTCB_CLOSE_PHYSICAL_PORT for target ports, FSF_QTCB_OPEN_LUN, FSF_QTCB_CLOSE_LUN. One example is slow queue processing which can cause follow-on errors, e.g. FSF_PORT_ALREADY_OPEN after FSF_QTCB_OPEN_PORT_WITH_DID timed out.

In case of problems detecting that new responses are waiting on the input queue, we sooner or later trigger adapter recovery due to an FSF request timeout (trace tag "fsrth_1"). FSF requests with FSF request timeout are: typically FSF_QTCB_ABORT_FCP_CMND; but theoretically also FSF_QTCB_EXCHANGE_CONFIG_DATA or FSF_QTCB_EXCHANGE_PORT_DATA via sysfs, FSF_QTCB_OPEN_PORT_WITH_DID or FSF_QTCB_CLOSE_PORT for WKA ports, FSF_QTCB_FCP_CMND for task management function (LUN / target reset). One or more pending requests can meanwhile have FSF_PROT_GOOD and FSF_GOOD because the channel filled in the response via DMA into the request's QTCB. In a theroretical case, inject code can create an erroneous FSF request on purpose. If data router is enabled, it uses deferred error reporting. A READ SCSI command can succeed with FSF_PROT_GOOD, FSF_GOOD, and SAM_STAT_GOOD. But on writing the read data to host memory via DMA, it can still fail, e.g. if an intentionally wrong scatter list does not provide enough space. Rather than getting an unsuccessful response, we get a QDIO activate check which in turn triggers adapter recovery. One or more pending requests can meanwhile have FSF_PROT_GOOD and FSF_GOOD because the channel filled in the response via DMA into the request's QTCB.

Typically this was the case for I/O requests resulting in a SCSI trace record "rsl_err" with DID_TRANSPORT_DISRUPTED [On ZFCP_STATUS_FSFREQ_DISMISSED, zfcp_fsf_protstatus_eval() sets ZFCP_STATUS_FSFREQ_ERROR seen by the request handler functions as failure]. However, the reason for this follow-on trace was invisible because the corresponding HBA trace record was missing at the default trace level (by default hidden records with tags "fs_norm", "fs_qtcb", or "fs_open"). On adapter recovery, after we had shut down the QDIO queues, we perform unsuccessful pseudo completions with flag ZFCP_STATUS_FSFREQ_DISMISSED for each pending FSF request in zfcp_fsf_req_dismiss_all(). In order to find the root cause, we need to see all pseudo responses even if the channel presented them successfully with FSF_PROT_GOOD and FSF_GOOD. Therefore, check zfcp_fsf_req.status for ZFCP_STATUS_FSFREQ_DISMISSED or ZFCP_STATUS_FSFREQ_ERROR and trace with a new tag "fs_rerr". It does not matter that there are numerous places which set ZFCP_STATUS_FSFREQ_ERROR after the location where we trace an FSF response early. These cases are based on protocol status != FSF_PROT_GOOD or == FSF_PROT_FSF_STATUS_PRESENTED and are thus already traced by default as trace tag "fs_perr" or "fs_ferr" respectively. NB: The trace record with tag "fssrh_1" for status read buffers on dismiss all remains. zfcp_fsf_req_complete() handles this and returns early. All other FSF request types are handled separately and as described above.

Nonetheless, use the conversion on the constant expression where possible.

The mac_esp driver neglects to explicitly ack them, which causes a timeout during messages larger than one byte (e.g. tag bytes during reconnect). Fix this with an ESP_CMD_MOK command after each byte. The MESSAGE IN phase is also different in that each byte transferred raises ESP_INTR_FDONE. So don't exit the transfer loop for this interrupt, for this phase. That resolves the "Reconnect IRQ2 timeout" error on those Macs which use PIO transfers instead of PDMA. This patch also improves on the weak tests for unexpected interrupts and phase changes during PIO transfers.

In a couple of cases esp_scsi doesn't do so. When the initiator receives an unhandled message, just respond by sending a MESSAGE REJECT instead of ABORT TASK SET, and thus avoid the issue. OTOH, a MESSAGE REJECT sent by a target can be taken as an indication that the initiator messed up somehow. It isn't always possible to abort correctly, so just fall back on a SCSI bus reset, which will complete the affected commands with the appropriate result code. For example, certain Apple (Sony) CD-ROM drives, when the non-existent LUN 1 is scanned, can't handle the INQUIRY command. The problem is not detected until the initiator gets a MESSAGE REJECT. Whenever esp_scsi sees that message, it raises ATN and sends ABORT TASK SET -- but neglects to complete the failed scmd. The target then goes into DATA OUT phase (probably bogus), while the ESP device goes into disconnected mode (surprising, given the bus phase). The next Transfer Information command from esp_scsi then causes an Invalid Command interrupt because that command is not valid when in disconnected mode: mac_esp: using PDMA for controller 0 mac_esp mac_esp.0: esp0: regs[50f10000:(null)] irq[19] mac_esp mac_esp.0: esp0: is a ESP236, 16 MHz (ccf=4), SCSI ID 7 scsi host0: esp scsi 0:0:0:0: Direct-Access SEAGATE ST318416N 0010 PQ: 0 ANSI: 3 scsi target0:0:0: Beginning Domain Validation scsi target0:0:0: asynchronous scsi target0:0:0: Domain Validation skipping write tests scsi target0:0:0: Ending Domain Validation scsi 0:0:3:0: CD-ROM SONY CD-ROM CDU-8003A 1.9a PQ: 0 ANSI: 2 CCS scsi target0:0:3: Beginning Domain Validation scsi target0:0:3: FAST-5 SCSI 2.0 MB/s ST (500 ns, offset 15) scsi target0:0:3: Domain Validation skipping write tests scsi target0:0:3: Ending Domain Validation scsi host0: unexpected IREG 40 scsi host0: Dumping command log scsi host0: ent[2] CMD val[c2] sreg[90] seqreg[cc] sreg2[00] ireg[20] ss[01] event[0c] scsi host0: ent[3] CMD val[00] sreg[91] seqreg[04] sreg2[00] ireg[18] ss[00] event[0c] scsi host0: ent[4] EVENT val[0d] sreg[91] seqreg[04] sreg2[00] ireg[18] ss[00] event[0c] scsi host0: ent[5] EVENT val[03] sreg[91] seqreg[04] sreg2[00] ireg[18] ss[00] event[0d] scsi host0: ent[6] CMD val[90] sreg[91] seqreg[04] sreg2[00] ireg[18] ss[00] event[03] scsi host0: ent[7] EVENT val[05] sreg[91] seqreg[04] sreg2[00] ireg[18] ss[00] event[03] scsi host0: ent[8] EVENT val[0d] sreg[93] seqreg[cc] sreg2[00] ireg[10] ss[00] event[05] scsi host0: ent[9] CMD val[01] sreg[93] seqreg[cc] sreg2[00] ireg[10] ss[00] event[0d] scsi host0: ent[10] CMD val[11] sreg[93] seqreg[cc] sreg2[00] ireg[10] ss[00] event[0d] scsi host0: ent[11] EVENT val[0b] sreg[93] seqreg[cc] sreg2[00] ireg[10] ss[00] event[0d] scsi host0: ent[12] CMD val[12] sreg[97] seqreg[cc] sreg2[00] ireg[08] ss[00] event[0b] scsi host0: ent[13] EVENT val[0c] sreg[97] seqreg[cc] sreg2[00] ireg[08] ss[00] event[0b] scsi host0: ent[14] CMD val[44] sreg[90] seqreg[cc] sreg2[00] ireg[20] ss[00] event[0c] scsi host0: ent[15] CMD val[01] sreg[90] seqreg[cc] sreg2[00] ireg[20] ss[01] event[0c] scsi host0: ent[16] CMD val[c2] sreg[90] seqreg[cc] sreg2[00] ireg[20] ss[01] event[0c] scsi host0: ent[17] CMD val[00] sreg[87] seqreg[02] sreg2[00] ireg[18] ss[00] event[0c] scsi host0: ent[18] EVENT val[0d] sreg[87] seqreg[02] sreg2[00] ireg[18] ss[00] event[0c] scsi host0: ent[19] EVENT val[06] sreg[87] seqreg[02] sreg2[00] ireg[18] ss[00] event[0d] scsi host0: ent[20] CMD val[01] sreg[87] seqreg[02] sreg2[00] ireg[18] ss[00] event[06] scsi host0: ent[21] CMD val[10] sreg[87] seqreg[02] sreg2[00] ireg[18] ss[00] event[06] scsi host0: ent[22] CMD val[1a] sreg[87] seqreg[ca] sreg2[00] ireg[08] ss[00] event[06] scsi host0: ent[23] CMD val[12] sreg[87] seqreg[ca] sreg2[00] ireg[08] ss[00] event[06] scsi host0: ent[24] EVENT val[0d] sreg[87] seqreg[ca] sreg2[00] ireg[08] ss[00] event[06] scsi host0: ent[25] EVENT val[09] sreg[86] seqreg[ca] sreg2[00] ireg[10] ss[00] event[0d] scsi host0: ent[26] CMD val[01] sreg[86] seqreg[ca] sreg2[00] ireg[10] ss[00] event[09] scsi host0: ent[27] CMD val[10] sreg[86] seqreg[ca] sreg2[00] ireg[10] ss[00] event[09] scsi host0: ent[28] EVENT val[0a] sreg[86] seqreg[ca] sreg2[00] ireg[10] ss[00] event[09] scsi host0: ent[29] EVENT val[0d] sreg[80] seqreg[ca] sreg2[00] ireg[20] ss[00] event[0a] scsi host0: ent[30] EVENT val[04] sreg[80] seqreg[ca] sreg2[00] ireg[20] ss[00] event[0d] scsi host0: ent[31] CMD val[01] sreg[80] seqreg[ca] sreg2[00] ireg[20] ss[00] event[04] scsi host0: ent[0] CMD val[90] sreg[80] seqreg[ca] sreg2[00] ireg[20] ss[00] event[04] scsi host0: ent[1] EVENT val[05] sreg[80] seqreg[ca] sreg2[00] ireg[20] ss[00] event[04] scsi target0:0:3: FAST-5 SCSI 2.0 MB/s ST (500 ns, offset 15) scsi target0:0:0: asynchronous sr 0:0:3:0: [sr0] scsi-1 drive cdrom: Uniform CD-ROM driver Revision: 3.20 sd 0:0:0:0: Attached scsi generic sg0 type 0 sr 0:0:3:0: Attached scsi generic sg1 type 5 This patch resolves this issue because the bus reset causes the INQUIRY command to fail earlier, and return the appropriate result code.

During an 1.) OS shutdown or 2.) kexec outside of a kdump, the Linux kernel will clear BME on our controller. If BME is cleared during a controller/host PCIe transfer, the controller will lock up. So we perform a PQI reset in the driver's shutdown callback function to eliminate the possibility of a controller/host PCIe transfer being active when the kernel clears BME immediately after calling the driver's shutdown callback.

Fix issue of controller reset required to send commands. For reset process, it may be required to send commands to the controller, but not during soft reset. So add HISI_SAS_NOT_ACCEPT_CMD_BIT to prevent executing a task during this period. 2. Send a broadcast event in rescan topology to detect any topology changes during reset. 3. Previously it was not ensured that libsas has processed the PHY up and down events after reset. Potentially this could cause an issue that we still process the PHY event after reset. So resolve this by flushing shot workqueue in LLDD reset. 4. Port ID requires refresh after reset. The port ID generated after reset is not guaranteed to be the same as before reset, so it needs to be refreshed for each device's ITCT.

This may be done via the /proc filesystem. -For example: - - echo "rescan" > /proc/scsi/cciss0/1 - -This causes the driver to query the adapter about changes to the -physical SCSI buses and/or fibre channel arbitrated loop and the -driver to make note of any new or removed sequential access devices -or medium changers. The driver will output messages indicating what -devices have been added or removed and the controller, bus, target and -lun used to address the device. It then notifies the SCSI mid layer -of these changes. - -Note that the naming convention of the /proc filesystem entries -contains a number in addition to the driver name. (E.g. "cciss0" -instead of just "cciss" which you might expect.) - -Note: ONLY sequential access devices and medium changers are presented -as SCSI devices to the SCSI mid layer by the cciss driver. Specifically, -physical SCSI disk drives are NOT presented to the SCSI mid layer. The -physical SCSI disk drives are controlled directly by the array controller -hardware and it is important to prevent the kernel from attempting to directly -access these devices too, as if the array controller were merely a SCSI -controller in the same way that we are allowing it to access SCSI tape drives. - -SCSI error handling for tape drives and medium changers -------------------------------------------------------- - -The linux SCSI mid layer provides an error handling protocol which -kicks into gear whenever a SCSI command fails to complete within a -certain amount of time (which can vary depending on the command). -The cciss driver participates in this protocol to some extent. The -normal protocol is a four step process. First the device is told -to abort the command. If that doesn't work, the device is reset. -If that doesn't work, the SCSI bus is reset. If that doesn't work -the host bus adapter is reset. Because the cciss driver is a block -driver as well as a SCSI driver and only the tape drives and medium -changers are presented to the SCSI mid layer, and unlike more -straightforward SCSI drivers, disk i/o continues through the block -side during the SCSI error recovery process, the cciss driver only -implements the first two of these actions, aborting the command, and -resetting the device. Additionally, most tape drives will not oblige -in aborting commands, and sometimes it appears they will not even -obey a reset command, though in most circumstances they will. In -the case that the command cannot be aborted and the device cannot be -reset, the device will be set offline. - -In the event the error handling code is triggered and a tape drive is -successfully reset or the tardy command is successfully aborted, the -tape drive may still not allow i/o to continue until some command -is issued which positions the tape to a known position. Typically you -must rewind the tape (by issuing "mt -f /dev/st0 rewind" for example) -before i/o can proceed again to a tape drive which was reset. - -There is a cciss_tape_cmds module parameter which can be used to make cciss -allocate more commands for use by tape drives. Ordinarily only a few commands -(6) are allocated for tape drives because tape drives are slow and -infrequently used and the primary purpose of Smart Array controllers is to -act as a RAID controller for disk drives, so the vast majority of commands -are allocated for disk devices. However, if you have more than a few tape -drives attached to a smart array, the default number of commands may not be -enough (for example, if you have 8 tape drives, you could only rewind 6 -at one time with the default number of commands.) The cciss_tape_cmds module -parameter allows more commands (up to 16 more) to be allocated for use by -tape drives.

Currently in the driver we've been using the fc_fcoe_set_mac() function to set the source MAC for FCoE traffic. This works well in most cases as it uses the spec. default FCF-MAC. However, if the administrator changes the FCF-MAC switch, then any FCoE traffic we send will be dropped by the switch. Instead we should check the granted MAC from the FLOGI payload and use that address if it is present. Otherwise, fall back to using the the default FCF-MAC and the fabric ID of the port as the FCoE MAC address.

Currently in the driver the qedf_ctx attribute vlan_hw_insert is used to which whether to insert a VLAN tag in FIP frames (except for FIP VLAN request which is explicitly sent out untagged at least from the driver's point of view). When we receive a FIP VLAN response, we set qedf->vlan_hw_insert to 0 which makes the qedf_fip_send function insert the VLAN. However when we exhaust our FIP VLAN retries, we do not set qedf->vlan_hw_insert to 0 which means that the driver will not tag the FIP frame with the correct VLAN ID. The result that was observed on the wire is that some entity either in the LL2 or L2 firmware is adding a NULL VLAN tag which can cause FIP solicitation to fail. The offload FCoE frame function, qedf_xmit, does not use the vlan_hw_insert attribute to decide whether to tag frames with the FIP/FCoE VLAN. Instead it unilaterially tags the offload frames with the VLAN ID stored in qedf->vlan_id. This is the correct behavior so the driver can guarantee that non-offload FIP frames go out with the correct VLAN ID. Also use the Linux network layer helpers instead of doing the VLAN insert manually. Also fix setting the fallback VLAN so that it used the module parameter and is not hardcoded to 1002 (though 1002 is the default).

During chip reset recovery process, driver notifies the transport layer that remote port no longer exist, by calling fc_remote_port_delete(). When this function is called, it actually delays deletion by "blocking" it. It sets the remote port state to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING. When driver tries to abort the command by calling its abort handler function, abort handler will wait until remote port state is blocked state or wait for dev_loss_tmo time. Due to this blocking, rport times out and results in an IO failure. This patch adds a check for any active reset process before calling abort handler function.

In Pt2Pt, the driver must send PRLI's for both (scsi) FCP and NVME rather than using fabric aids. The driver was inconsistent on handling various PRLI completions, especially rejects, which had reject codes cross the different protocol PRLI completions. Fixed to perform the following: if nvmet mode (fc port can only be a nvme target) - rejects all unsolicitly FCP PRLI's. Never issues a FCP PRLI. The multiple protocol PRLI's are sent simultaneously. However, driver will now only state transition after both PRLI's are complete. New flags were added to aid tracking the responses from the different PRLI's.

After lip, the driver sometimes would have two rports for the same device, allowing the namespaces to be duplicated by nvme. In lpfc_plogi_confirm_nport() the driver was not swapping the nrport maintained by the ndlp's undergoing address swapping. This allowed the 2nd rport to sneak in as it was considered a separate device. This patch adds the fixes to Swap the nrport in each ndlp and take care of the reference counts on the ndlps similar to FCP rports.

For asynchronously received ius where the driver must assign exchange resources, the resources were on a single get (free) list and put list (finished, waiting to be put on get list). As all cpus are sharing the lists, an interrupt for a receive frame may have to wait for all the other cpus to place their done work onto the put list before it can acquire the lock to pull from the list. Fix by breaking the resource lists into per-cpu lists or at least more than 1 list with cpu's sharing the lists). A cpu would allocate from the free list for its own cpu, and put its done work on the its own put list - avoiding the contention. As cpu load may vary, when empty, a cpu may grab from another cpu, thereby changing resource distribution. But searching for a resource only occurs on 1 or a few cpus until a single resource can be allocated. if the condition reoccurs, it starts looking at a different cpu.

There were conflicting NVME SGL posting/reposting responsibilities between lpfc_online()/lpfc_sli4_hba_setup() and lpfc_nvme_create_localport(). The lpfc_online() causes a REPOST on existing NVME SGLs which is not released during the fc port reset. However, lpfc_nvme_create_localport() wants to allocate new NVME buffers and post them. Both cancelled out each other which had a side effect of hosing the mailbox handling that was used to remove the sgl lists - causing multiple 60s mbx timeouts.

Make this change where appropriate. Although this patch does not change any functionality, it slightly improves performance and slightly improves readability.

Several places throughout the aacraid driver call aac_fib_send or similar to send a command to the aacraid adapter, then check the return code to determine if the command was actually sent to the adapter, then update the phase field in the scsi command scratch pad area to track that the firmware now owns this command. However, there is nothing that ensures that by the time the aac_fib_send function returns and we go to write to the scsi command, that the command hasn't already completed and the scsi command has been freed. This was causing random crashes in the TCP stack which was tracked down to be caused by memory that had been a struct request + scsi_cmnd being now used for an skbuff. Memory poisoning was enabled in the kernel to debug this which showed that the last owner of the memory that had been freed was aacraid and that it was a struct request. The memory that was corrupted was the exact data pattern of AAC_OWNER_FIRMWARE and it was at the same offset that aacraid writes, which is scsicmd->SCp.phase. The patch below resolves this issue.

Use kfree_rcu() instead of kfree() to free VPD data. Move the VPD buffer pointer check inside the RCU read lock in the sysfs code. Only annotate pointers that are shared across threads with __rcu. Use rcu_dereference() when dereferencing an RCU pointer. This patch suppresses about twenty sparse complaints about the vpd_pg8[03] pointers. This patch also fixes a race condition, namely that updating of the VPD pointers and length variables in struct scsi_device was not atomic with reference to the code reading these variables.

When we add "start + size" it could lead to an integer overflow bug. It means we vmalloc() a lot more memory than we had intended. I believe that on 64 bit systems vmalloc() can succeed even if we ask it to allocate huge 4GB buffers. So we would get memory corruption and likely a crash when we call ha->isp_ops->write_optrom() and ->read_optrom(). Only root can trigger this bug.
