block: do not pass disk names as format strings

2013-07-13T18:42:26+00:00

commit ffc8b30866879ed9ba62bd0a86fecdbd51cd3d19 upstream.

Disk names may contain arbitrary strings, so they must not be
interpreted as format strings.  It seems that only md allows arbitrary
strings to be used for disk names, but this could allow for a local
memory corruption from uid 0 into ring 0.

driver-core: constify data for class_find_device()

2013-02-06T20:18:56+00:00

All in-kernel users of class_find_device() don't really need mutable
data for match callback.

In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c)
this patch changes match callbacks to use const search data.

The const is propagated to rtc_class_open() and power_supply_get_by_name()
parameters.

Note that there's a dev reference leak in suspend_test.c that's not
touched in this patch.

[SCSI] osd_uld: Add osdname & systemid sysfs at scsi_osd class

2012-11-27T04:59:34+00:00

This patch adds the support for the following two read-only sysfs attributes
to scsi_osd class members : osdname & systemid

These attributes will show up as below in sysfs class hierarchy:
/sys/class/scsi_osd/osdX/osdname
/sys/class/scsi_osd/osdX/systemid

The osdname & systemid are OSD device attributes which uniquely
identify a device on the network, while it's IP and certainly
it's /dev/osdX device path might change.
Userspace utilities (e.g. mkfs.exofs) can parse these attributes to
identify the correct OSD in safer and faster way.

(Today osd apps open each device in the system and send a
 attributes query for these, in order to access the user
 requested device)

[SCSI] osd_uld: Bump MAX_OSD_DEVICES from 64 to 1,048,576

2012-02-25T14:25:09+00:00

It used to be that minors where 8 bit. But now they
are actually 20 bit. So the fix is simplicity itself.

I've tested with 300 devices and all user-mode utils
work just fine. I have also mechanically added 10,000
to the ida (so devices are /dev/osd10000, /dev/osd10001 ...)
and was able to mkfs an exofs filesystem and access osds
from user-mode.

All the open-osd user-mode code uses the same library
to access devices through their symbolic names in
/dev/osdX so I'd say it's pretty safe. (Well tested)

This patch is very important because some of the systems
that will be deploying the 3.2 pnfs-objects code are larger
than 64 OSDs and will stop to work properly when reaching
that number.

scsi: Fix up files implicitly depending on module.h inclusion

2011-10-31T23:31:24+00:00

The module.h header was implicitly present everywhere, so files
with no explicit include of the module infrastructure would build
anyway.  We are now removing the implicit include, and so we need
to call out the module.h file that we need explicitly.

osd: Kconfig remove wrong FIXME

2011-09-22T11:14:05+00:00

The OSD protocol calls for all kind of security levels that use
CRYPTO_HMAC and SH1, but the current code only supports NO_SEC,
which does not use any of these.

Remove a wrong FIXME that calls for them. Thanks Maxin for
reporting on this.

[SCSI] libosd: osd_req_read_sg, optimize the single entry case

2011-01-24T18:06:31+00:00

Since sg-read is a bidi operation, it is a gain to convert
a single sg entry into a regular read. Better do this in the
generic layer then force each caller to do so.
