When logging async events, also print the payload in addition to the
event received.

[SCSI] ibmvfc: Sanitize response lengths

2008-08-16T15:49:01+00:00

Sanitize the response lengths in order to prevent possible oopses
in the command response path.

[SCSI] ibmvfc: Fix for lost async events

2008-08-16T15:48:40+00:00

If the client virtual fibre channel adapter is already logged into the
server and does an NPIV Login again, the async queue, which is used for
reporting Link Up/Link Down type of events, does not get reset on the
server side. Fix up the client driver so that we also do not reset it.
This fixes a problem of lost async events following relogins.

[SCSI] ibmvfc: Fixup host state during reinit

2008-08-16T15:48:25+00:00

If an ELS is received while the virtual fibre channel adapter is going
through its discovery, a flag is set which causes discovery to get
re-driven. However, the hosts's state does not get set back to
IBMVFC_INITIALIZING and scsi_block_requests does not get called again,
which can result in queuecommand ops getting sent during
discovery. This should not occur and may cause problems. One example
is that we may no longer be logged into the target we send the command
to, resulting in a failure which should not have occurred.

[SCSI] ibmvfc: Fix another hang on module removal

2008-08-16T15:47:46+00:00

This fixes a hang on module removal. The module removal code was setting
the hosts's state to IBMVFC_HOST_OFFLINE before tearing down the kernel
thread, but, due to a bug in ibmvfc_wait_while_resetting, was not waiting
for the kernel thread's offlining work to be done prior to destroying
the kernel thread, which left the scsi host in a blocked state which we
never got out of.

[SCSI] ibmvscsi: Fixup desired DMA value for shared memory partitions

2008-08-16T15:33:01+00:00

When running ibmvscsi in a shared memory partition, it must provide
a default value for the amount of DMA resources it will need in order to
perform reasonably well. This was being calculated in sectors rather than
bytes, as it should. This patch fixes this.

[SCSI] megaraid_sas: remove sysfs dbg_lvl world writeable permissions

2008-08-16T15:32:24+00:00

/sys/bus/pci/drivers/megaraid_sas/dbg_lvl defaults to being
world-writable, which seems bad (letting any user affect kernel driver
behavior and logging level).

This turns off group and user write permissions, so that on typical
production systems only root can write to it.
