* [SCSI] libiscsi: fix iscsi cmdsn allocationMike Christie2007-06-02
| | | | | | | | | | | | | | | | | | | | | The cmdsn allocation and pdu transmit code can race, and we can end up sending a pdu with cmdsn 10 before a pdu with 5. The target will then fail the connection/session. This patch fixes the problem by delaying the cmdsn allocation until we are about to send the pdu. This also removes the xmitmutex. We were using the connection xmitmutex during error handling to handle races with mtask and ctask cleanup and completion. For ctasks we now have nice refcounting and for the mtask, if we hit the case where the mtask timesout and it is floating around somewhere in the driver, we end up dropping the session. And to handle session level cleanup, we use the xmit suspend bit along with scsi_flush_queue and the session lock to make sure that the xmit thread is not possibly transmitting a task while we are trying to kill it.

* [SCSI] iscsi tcp: fix iscsi xmit state machineMike Christie2007-06-01
| | | | | | | | | | If iscsi_tcp partially sends a header, it would recalculate the header size and readd the size of the digest (if header digests are used).This would cause us to send sizeof(digest) extra bytes when we sent the rest of the header.

* [SCSI] iscsi class, iscsi_tcp, ib_iser: add sysfs chap fileMike Christie2007-06-01
| | | | | | | | | | | | | | The attached patches add sysfs files for the chap settings to the iscsi transport class, iscsi_tcp and ib_iser. This is needed for software iscsi because there are times when iscsid can die and it will need to reread the values it was using. And it is needed by qla4xxx for basic management opertaions. This patch does not hook in qla4xxx yet, because I am not sure the mbx command to use.

* [SCSI] iscsi class, qla4xxx, iscsi_tcp, ib_iser: export/set initiator nameMike Christie2007-06-01
| | | | | | | | | | | | | | | For iscsi root boot, software iscsi needs to know what the BIOS/OF initiator used for the initiator name so this puts it in sysfs for userspace to be able to pick up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | complete Every so often, the driver will call asd_clear_nexus to clean out a task. It is supposed to be the case that the CLEAR NEXUS does not go on the done list until after the task itself has been put on the done list, but for some reason this doesn't always happen. Thus, the wait_for_completion_timeout call times out, and we return success. This makes libsas free the task even though the task hasn't completed, leading to a BUG_ON message from aic94xx_hwi.c around line 341. We should return failure from asd_clear_nexus so that libsas tries again; at a bare minimum it shouldn't be freeing active tasks. I _think_ this will fix one of the SCB timeout crash problems (though I've not been able to reproduce it lately...) Signed-off-by: Darrick J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under some conditions associated with the unclean transition to kdump, the aacraid adapters will view the array as foreign and not export it to prevent access and data manipulation. The solution is to submit a commit configuration to export the devices since this is a expected behavior when transitioning to a kdump kernel. This patch adds the aacraid.reset_devices flag and when either this or the global reset_devices flag is set, ensures that a commit config is issued and extends the startup_timeout if it is set less than 5 minutes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After reset completed, the scsi error handler sends out TEST_UNIT_READY to the device. For 'normal' devices the command will be handled by firmware. However, because the RAID console only interfaces to scsi mid layer, the firmware will not process the command for it. This will make the console to be offlined right after reset. Add the handling in driver to fix this problem.

| | * [SCSI] stex: extend hard reset wait timeEd Lin2007-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | During hard bus reset of st_shasta controllers, 1 ms is not enough for 16-port controllers, although it's good for 8-port controllers. Extend the wait time to 100 ms to allow bus resets finish successfully. Signed-off-by: Ed Lin <ed.lin@promise.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| | * [SCSI] stex: fix id mapping issueEd Lin2007-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The correct internal mapping of stex controllers should be: id:0~15, lun:0~7 (st_shasta) id:0, lun:0~127 (st_yosemite) id:0~127, lun:0 (st_vsc and st_vsc1) This patch reports the internal mapping to scsi mid layer, eliminating the translation between scsi mid layer and firmware. To achieve this goal, we also need to: -- fail the REPORT_LUNS command for st_shasta because the firmware is known to not report all actual luns -- add an entry in scsi_devindo.c to force sequential lun scan (for st_shasta controllers) -- fail the REPORT_LUNS command for console device -- remove special handling of REPORT_LUNS command for st_yosemite, as there is no translation mapping now Signed-off-by: Ed Lin <ed.lin@promise.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| | * [SCSI] ipr: Proper return codes for eh_dev_reset for SATA devicesBrian King2007-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ipr always returns success from eh_dev_reset when called for a SATA device. If ata_do_eh is unable to recover for some reason, this can result in commands that are still outstanding when ata_do_eh returns. Change ipr to verify no commands are outstanding before returning success. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * | Detach sched.h from mm.hAlexey Dobriyan2007-05-21
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.
