Driver crashes if the BIOS do not set up at least one memory I/O resource. This failure can happen if the device is too slow to respond during POST and is missed by the BIOS, but Linux then detects the device later in the boot process.

This patch removes 21 casts between an __iomem pointer type and another data type but also introduces five new casts (see also the casts with "__force"). Although this patch does not change any functionality, IMHO the code with __force casts needs further review. Signed-off-by:

Whether htonl() or __constant_htonl() is used, if the argument is a constant the conversion happens at compile time. Hence leave out the __constant_ prefix for this and other endianness conversion functions. This improves source code readability. [jejb: checkpatch fixes] Signed-off-by:

These are signed values the come from the user, we put a cap on the upper bounds but not on the lower bounds. We use "karg.dataSgeOffset" to calculate "sz". We verify "sz" and proceed as if that means that "karg.dataSgeOffset" is correct but this fails to consider that the "sz" calculations can have integer overflows. Signed-off-by:

Under the 'default' case in scmnd->sc_data_direction we have 3 options: - DMA_NONE which we handle correctly. - DMA_BIDIRECTIONAL which is never supposed to be set by SCSI stack. - Garbage value. Do WARN() and return -EINVAL in the last two cases. virtio_scsi does BUG_ON() here but it looks like an overkill. Reported-by:

Commit f3ddac19 ("[SCSI] qla2xxx: Disable adapter when we encounter a PCI disconnect.") has introduced a code that disables the board, releasing some resources, when reading 0xffffffff. In case this happens when there is an EEH, this read will trigger EEH detection and set PCI channel offline. EEH will be able to recover the card from this state by doing a reset, so it's a better option than simply disabling the card. Since eeh_check_failure will mark the channel as offline before returning the read value, in case there really was an EEH, we can simply check for pci_channel_offline, preventing the board_disable code from running if it's true. Without this patch, EEH code will try to access those same resources that board_disable will try to free. This race can cause EEH recovery to fail.

The iSCSI session recovery_tmo setting is writeable in sysfs, but it's also set every time a connection is established when parameters are set from iscsid over netlink. That results in the timeout being reset to the default value after every recovery. The DM multipath tools want to use the sysfs interface to lower the default timeout when there are multiple paths to fail over. It has caused confusion that we have a writeable sysfs value that seem to keep resetting itself. This patch adds an in-kernel flag that gets set once a sysfs write occurs, and then ignores netlink parameter setting once it's been modified via the sysfs interface. My thinking here is that the sysfs interface is much simpler for external tools to influence the session timeout, but if we're going to allow it to be modified directly we should ensure that setting is maintained.

The 'sd' driver is calling scsi_mode_sense() to figure out internal details. But scsi_mode_sense() never checks for any pending unit attentions, so we're getting annoying error messages like: MODE SENSE: unimplemented page/subpage: 0x00/0x00 and a possible wrong decision for device cache handling.
