2006-05-03[SCSI] mptspi: revalidate negotiation parameters after host reset and resumeEric Moore
This is a bug fix for mptspi driver, where after a host reset or resume, we revalidate the negotiation parameters for all devices. This bug was introduced when the driver was ported to use the spi transport layer. Signed-off-by: Eric Moore <Eric.Moore@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-04-27[SCSI] qla2xxx: Correct eh_abort recovery logic.Michael Reed
Fix the driver to return SUCCESS if the firmware or driver doesn't have a command to abort, i.e., it's already been returned. Without this patch, error recovery will take the target offline as it tries harder and harder to get the driver to return the command it no longer has.

2006-04-27[SCSI] megaraid_{mm,mbox}: fix a bug in reset handlerJu, Seokmann
When abort failed, the driver gets reset handleer called. In the reset handler, driver calls 'scsi_done()' callback for same SCSI command packet (struct scsi_cmnd) multiple times if there are multiple SCSI command packet in the pend_list. More over, if there are entry in the pend_lsit with IOCTL packet associated, the driver returns it to wrong free_list so that, in turn, the driver could end up with 'NULL pointer dereference..' during I/O command building with incorrect resource. Also, the patch contains several minor/cosmetic changes besides this.

Some versions of the IBM 2104-DU3 disk enclosure have been observed to hang Inquiries to non zero LUNs to the SES device.

2006-04-25[SCSI] - fusion - mptfc bug fix's to prevent deadlock situationsMoore, Eric
mptbase.h bump version number to 3.03.09 remove unneeded flags define workq and remove old fc specific locks mptbase.c initialize new lock and don't initialize two removed locks mptscsih.c when firmware reports target is no longer there, return DID_REQUEUE for fc hosts so that i/o doesn't get killed until the transport has an opportunity to manage the loss via its dev loss timer when the "eh_abort" routine is called, check to see if the driver has the command or not before looking to see if a reset is pending. James Smart and I talked about this and believe that the API for this routine is: if driver doesn't have command, return SUCCESS. This change helps prevent a target from being taken offline. SUCCESS is returned because it's likely that the command completed after error recovery timed it out but before it could be aborted. provide a routine to queue work to newly created workq, and use it. remove "ioc" from mptscsih_abort() it was only used one time. the other references were via hd->ioc, so I just moved it.... net change in references to ioc via hd->ioc is zero move hd->resetPending test and hd->timeouts increment to after the test for whether the command to be aborted remains known to the driver Make certain that the workq exists before queuing work to it. mptfc.c no longer need to lock rport data structures as I was able to single thread the code! I fixed up the debug code to eliminate compilation messages due to type mismatch in the printk. Got rid of some no longer needed rport flags. Initialize and destroy the workq used for the rescan work. simplify the logic regarding the increment of fc_rescan_work_count. use post increment and test for zero vs. pre increment and test for one; eliminate work_count variable: queue_work can be called with the work_lock held as it doesn't sleep Signed-off-by: Michael Reed <mdr@sgi.com> Signed-off-by: Eric Moore <Eric.Moore@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

If qla2x00_probe_one() fails before calling request_irq() but gets to qla2x00_free_device() then it will mistakenly try to free an irq it didn't request. It's chosing to free based on ha->pdev->irq which is always set. host->irq is set after request_irq() succeeds so let's use that to decide to free or not.

2006-04-18[CPUFREQ] If max_freq got reduced (e.g. by _PPC) a write to sysfs ↵Thomas Renninger
scaling_governor let cpufreq core stuck at low max_freq for ever The previous patch had bugs (locking and refcount). This one could also be related to the latest DELL reports. But they only slip into this if a user prog (e.g. powersave daemon does when AC got (un) plugged due to a scheme change) echos something to /sys/../cpufreq/scaling_governor while the frequencies got limited by BIOS. This one works: Subject: Max freq stucks at low freq if reduced by _PPC and sysfs gov access The problem is reproducable by(if machine is limiting freqs via BIOS): - Unplugging AC -> max freq gets limited - echo ${governor} >/sys/.../cpufreq/scaling_governor (policy->user_data.max gets overridden with policy->max and will never come up again.) This patch exchanged the cpufreq_set_policy call to __cpufreq_set_policy and duplicated it's functionality but did not override user_data.max. The same happens with overridding min/max values. If freqs are limited and you override the min freq value, the max freq global value will also get stuck to the limited freq, even if BIOS allows all freqs again. Last scenario does only happen if BIOS does not reduce the frequency to the lowest value (should never happen, just for correctness...) drivers/cpufreq/cpufreq.c | 17 +++++++++++++++-- 1 files changed, 15 insertions(+), 2 deletions(-) Signed-off-by: Thomas Renninger <trenn@suse.de> Signed-off-by: "Pallipadi, Venkatesh" <venkatesh.pallipadi@intel.com> Signed-off-by: Dave Jones <davej@redhat.com>
