* [NETNS]: Consolidate kernel netlink socket destruction.Denis V. Lunev2008-01-282-3/+3
| | | | | | | | | | Create a specific helper for netlink kernel socket disposal. This just let the code look better and provides a ground for proper disposal inside a namespace.

* [ETH]: Combine format_addr() with print_mac().Michael Chan2008-01-281-13/+1
| | | | | | | | | | | | | | | | | | | print_mac() used many most net drivers and format_addr() used by net-sysfs.c are very similar and they can be intergrated. format_addr() is also identically redefined in the qla4xxx iscsi driver. Export a new function sysfs_format_mac() to be used by net-sysfs, qla4xxx and others in the future. Both print_mac() and sysfs_format_mac() call _format_mac_addr() to do the formatting. Changed print_mac() to use unsigned char * to be consistent with net_device struct's dev_addr. Added buffer length overrun checking as suggested by Joe Perches.

| * blktrace: Add blktrace ioctls to SCSI generic devicesChristof Schmitt2008-01-281-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the SCSI layer uses the request queues from the block layer, blktrace can also be used to trace the requests to all SCSI devices (like SCSI tape drives), not only disks. The only missing part is the ioctl interface to start and stop tracing. This patch adds the SETUP, START, STOP and TEARDOWN ioctls from blktrace to the sg device files. With this change, blktrace can be used for SCSI devices like for disks, e.g.: blktrace -d /dev/sg1 -o - | blkparse -i - Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* | SG: work with the SCSI fixed maximum allocations.James Bottomley2008-01-281-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | SCSI sg table allocation has a maximum size (of SCSI_MAX_SG_SEGMENTS, currently 128) and this will cause a BUG_ON() in SCSI if something tries an allocation over it. This patch adds a size limit to the chaining allocator to allow the specification of the maximum allocation size for chaining, so we always chain in units of the maximum SCSI allocation size.

I merely expanded the fib lock to include the fib context. There have been no field reports of any issues generally because the applications are relatively static and do not come and go often enough to stress this area.

| * [SCSI] use dynamically allocated sense bufferFUJITA Tomonori2008-01-233-3/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes static array sense_buffer in scsi_cmnd and uses dynamically allocated sense_buffer (with GFP_DMA). The reason for doing this is that some architectures need cacheline aligned buffer for DMA: http://lkml.org/lkml/2007/11/19/2 The problems are that scsi_eh_prep_cmnd puts scsi_cmnd::sense_buffer to sglist and some LLDs directly DMA to scsi_cmnd::sense_buffer. It's necessary to DMA to scsi_cmnd::sense_buffer safely. This patch solves these issues. __scsi_get_command allocates sense_buffer via kmem_cache_alloc and attaches it to a scsi_cmnd so everything just work as before.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cards being added are supported in a limited sense already through family matching, but we needed to add some functionality to the driver to expose selectively the physical drives. These Physical drives are specifically marked to not be part of any array and thus are declared JBODs (Just a Bunch Of Drives) for generic SCSI access. We report that this is the second patch in a set of two, but merely depends on the stand-alone functionality of the first patch which adds in that case the ability to report a driver feature flag via sysfs. We leverage that functionality by reporting that this driver now supports this new JBOD feature for the controller so that the array management applications may react accordingly and guide the user as they manage the controller.

Breaking from the one-line output typical of sysfs entries, newline was added to tailor for grep, or simple gets line by line string match within an application. I added one for a compiler time check for existence of debug print output, one for an optional manifest defined enhanced status reporting in the logs, and one for runtime reporting whether the controller and driver supports arrays larger than 2TB. Adaptec's storage management software uses the last flag to determine whether to make available the creation of arrays larger than 2TB, otherwise a warning is posted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: <debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.

This breaks on 32-bit platforms which support 64-bit MMIO resources. Correct code by removing the temporary variables used during MMIO PIO mapping and using resource_size_t where applicable. Also correct a small typo in a printk() where the wrong region number was displayed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Actually there are several but one is trivially fixed 1. FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list but needs to 2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB 3. It is possible to construct an attack via the SRB ioctls where the user obtains assorted elevated privileges. Various approaches are possible, the trivial ones being things like writing to the raw media via scsi commands and the swap image of other executing programs with higher privileges. So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating ones. This is a bandaid fix for #3 but probably the ioctls should grow their own capable checks. The other two bugs need someone competent in that driver to fix them.
