Some SCSI devices use the same WWN and have a WWN extension that we
need to take into account when creating the /dev/disk/by-id/wwn
symlinks. Thus, introduce ID_WWN_WITH_EXTENSION. This property will
contain either the WWN (if no extension is present) or the WWN with
the vendor extension appended.
Example:
# /lib/udev/ata_id/ata_id --export /dev/sda |grep WWN
ID_WWN=0x5001517387d61905
ID_WWN_WITH_EXTENSION=0x5001517387d61905
# /lib/udev/scsi_id --whitelisted --export -d /dev/sdb |grep WWN
ID_WWN=0x600508b400105df7
ID_WWN_VENDOR_EXTENSION=0x0000e00000d80000
ID_WWN_WITH_EXTENSION=0x600508b400105df70000e00000d80000
# /lib/udev/scsi_id --whitelisted --export -d /dev/sdc |grep WWN
ID_WWN=0x600508b400105df7
ID_WWN_VENDOR_EXTENSION=0x0000e00000db0000
ID_WWN_WITH_EXTENSION=0x600508b400105df70000e00000db0000

Since the Unit Serial Number and the WWN are useful bits of
information export them as properties in the udev database. These
bits of information are often printed on the physical disk, see
http://people.freedesktop.org/~david/FUJITSU-MAY2036RC-sas-disk-picture.jpg
and displaying them separately in the UI (or in /dev/disk) might help
users identify the physical disk. This patch exports these bits of
information as ID_WWN and ID_SCSI_SERIAL.
Note that ata_id also use the ID_WWN property since commit
66094a4a7f (2009-11-04).
Also print out ID_SCSI=1 so users of the udev database knows the disk
speaks SCSI.
Here's the scsi_id output from one of my SAS disks with these changes:
ID_SCSI=1
ID_VENDOR=FUJITSU
ID_VENDOR_ENC=FUJITSU\x20
ID_MODEL=MAY2036RC
ID_MODEL_ENC=MAY2036RC\x20\x20\x20\x20\x20\x20\x20
ID_REVISION=0103
ID_TYPE=disk
ID_SERIAL=3500000e01b83f520
ID_SERIAL_SHORT=500000e01b83f520
ID_WWN=0x500000e01b83f520
ID_SCSI_SERIAL=B3G1P8500RWT
Unfortunately we can't overload ID_SERIAL for two reasons
1. ID_SERIAL (and ID_SERIAL_SHORT) exported by scsi_id isn't really
the unit serial number (as defined by SCSI) - it is sometimes the
WWN (since it is more unique than the Unit Serial Number) and
complex rules (to make the serial unique) govern what value to
use.
2. It would break existing setups if the value of ID_SERIAL changed

So ID_MODEL and ID_VENDOR are pretty useful keys. However since we fix
them up (removing leading/trailing whitespace, converts spaces to
underscores) for use in device naming etc. we also force these fixups on
the desktop shell. And this looks pretty ugly.
The attached patch introduces the ID_MODEL_ENC and ID_VENDOR_ENC keys
that contains the encoded version of the raw strings obtained. It's
pretty similar in spirit to ID_FS_LABEL and its cousin ID_FS_LABEL_ENC.
With this patch a desktop shell can fix up these strings as it sees fit.
Note that some fixup is still needed though, for example
# /lib/udev/ata_id --export /dev/sda |grep ID_MODEL
ID_MODEL=INTEL_SSDSA2MH080G1GC
ID_MODEL_ENC=INTEL\x20SSDSA2MH080G1GC\x20\x20\x20\x20\x20\x20\x20\x20
\x20\x20\x20\x20\x20\x20\x20\x20\x20\x20\x20
Note the trailing and leading whitespace. Anyway with the attached patch
the desktop shell should be able to display "INTEL SSDSA2MH080G1GC"
rather than "INTEL_SSDSA2MH080G1GC" to the user.
The problem was strncpy() doesn't stop after writing the terminating
NUL; by definition it goes on to zero the entire buffer.
I spy another use of strncpy in udev_device_add_property_from_string(),
which is responsible for another ~1% user cpu time...

This scheme is more consistent and makes it obvious if a match happens
against the event device only, or the full chain of parent devices.
The old key names are now:
BUS -> SUBSYSTEMS
ID -> KERNELS
SYSFS -> ATTRS
DRIVER -> DRIVERS
Match keys for the event device:
KERNEL
SUBSYSTEM
ATTR
DRIVER (in a future release, for now the same as DRIVERS)
Match keys for all devices along the parent device chain:
KERNELS
SUBSYSTEMS
ATTRS
DRIVERS
ID, BUS, SYSFS are no longer mentioned in the man page but still work.
DRIVER must be converted to DRIVERS to match the new scheme. For now,
an error is logged, if DRIVER is used. In a future release, the DRIVER
key behaviour will change.
Request specific parents identified by subsystem and don't rely on
a predefined sequence.
Also let the devpath be longer than 72 chars, tsss ...

We never used any of the libsysfs convenience features. Here we replace
it completely with 300 lines of code, which are much simpler and a bit
faster cause udev(d) does not open any syfs file for a simple event which
does not need any parent device information.

/tmp is not writable on most systems, so just use /dev to create a
temporary node. If called from a udev rule, "-d $tempnode" should be
used and udev will create a temporary node and pass the name before
calling scsi_id.
Also remove gen_scsi_id_udev_rules.sh per Patrick's request, as it's
no longer needed with the persistent disk links.

This patch is to enable the use of scsi_id to derive a UID for a SCSI-2
device which is not compliant with the page 83 inquiry reply format for
either SPC-2 or SPC-3. In this case, the page 83 reply does not
contain a list of Identification descriptors but a single binary encoded
hexa-decimal Vendor Specified Identifier.
The update is being driven by the need for scsi_id to support older
model EMC Symmetrix hardware, that is, models 4, 5, and 6.
Solaris uses volume_id now and they fiddled around with configure scripts
to map the linux kernel int types. Adding the types locally to volume_id
breaks the klibc build, so just switch to these ugly types and forget it. :)

Export the type of device from ata_id and scsi_id, also strip
leading and trailing whitespace and substitute consecutive
whitespace with a single underline char.

Update scsi_id to work with the libsysfs changes in udev: use
sysfs_get_classdev_attr and sysfs_get_device_attr in place of
sysfs_read_attribute_value.
Changes to scsi_id to support the udev %N and %p substitutions:
- Update version from .7 to .8
- change TMP_DIR back to /tmp
- if DEVPATH is set assume hotplug_mode (use syslog for logging, and does
not output some warnings)
- Always output a newline after the id is printed
- Allow command line options to override settings when hotplug_mode is set
- update man page
- update generator script to use the %N and %p substitutions.
