/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.
vol_id segfaults if read() fails on broken devices reporting

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.
udev can create the temporary node for us now. (On bootup we don't
know where a writable filesystem is mounted). Also the parent handling
is not needed anymore, cause udev is able to pass us the node name
of the parent device.
Adding prototypes for functions resulted in an error, cause:
table_find_disk(disk_snum, &chassis_num, &slot_num);
is called but the function is defined as:
int table_find_disk(char *serialnumber , int *host_num, int *chassis_num, int *slot_num)
which can obviously not work correctly.
Using popen() is not klibc compatible, so skip the compilation if
a klibc compile is requested.
The -d option in udev_allows to go from a partition to the underlying disk
for s390 dasd labels. If the device is already the disk itself, finding the
parent will fail, therefore -d on /sys/block/dasda/ for example gives no
result at all.
Fix FAT label reading bug for very large volumes.
Recognize FAT label at Win98 formatted volumes.
Read iso9660 joliet descriptor for unicode labels.
Support uuid/label of swap partitions.
Here is the first patch to cleanup the internal processing of the
various stages of an udev event. It should not change any behavior,
but if your system depends on udev, please always test it before reboot :)
We pass only one generic structure around between add, remove,
namedev, db and dev_d handling and make all relevant data available
to all internal stages. All udev structures are renamed to "udev".
We replace the fake parameter by a flag in the udev structure.
We open the class device in the main binaries and not in udev_add, to
make it possible to use libsysfs for udevstart directory crawling.
The last sleep parameters are removed.
Let's try it another way:
We define BLKGETSIZE64 in udev-volume_id.c now, cause including <fs.h>
does also not work with klibc. This hopefully fixes your compile problem
too.
Also included is an update to udev_volume_id with the latest fixes for
volume_id. It adds a simple logging file to map the debug function, that
we can use exactly the same files in HAL and udev.
Here is an update for the volume_id callout to catch up to the latest
and greatest:
o It is able to skip the label reading of linux raid members, which are
otherwise recognized as a normal filesystem.
o It reads FAT labels stored in the directory instead of the
superblock (Windows only writes in the directory).
o The NTFS uuid is the right one now.
o It reads all the Apple HFS(+) formats with the labels.
o UFS volumes are recognized but no labels are extracted.
o We use CFLAGS+=-D_FILE_OFFSET_BITS=64 instead of lsee64() which may fix
a bug mentioned on the klibc mailing list.
A lot of other new features are only used in HAL and not needed in this
simple callout. But if someone stumbles over it and want's to send a patch
for some exotic formats, we better keep it up to date :)
The attached patch contains a few patches against udev, to remove
use of various XSI:isms and bash:isms, and to change two scripts form
/bin/bash to /bin/sh. None of the bash-scripts in test/ uses any
bash-specific functions as far as I know, but I didn't touch them since
they aren't used runtime.
Rationale:
* Both of the /bin/bash-scripts are totally free from bashisms, hence they
don't need to be /bin/bash; using /bin/sh instead helps (mainly)
embedded-people
* local and source are bash:isms (well, they exist in several other
shells as well, but they aren't part of POSIX or any of its extensions)
* -a in tests is an XSI-extension, not part of strict POSIX, and is
easily replaced by &&
| http://www.opengroup.org/onlinepubs/009695399/utilities/test.html
* Use of fgrep is deprecated in POSIX in favour of grep -F (though fgrep
will remain in use for a long time...)
| http://www.opengroup.org/onlinepubs/009695399/utilities/grep.html
The fgrep-change isn't really necessary, since fgrep can always be
implemented as a shell-script, but the rest of the changes would really
be appreciated.
First, update extras/start_udev. udevstart always internally set
UDEV_NO_SLEEP as well as setting the ACTION variable, so that only needs

volume_id is now able to read NTFS labels. Not very exciting, but we
keep up to date with the version in HAL. Also __packed__ was needed for
the structs, cause the gcc 3.4 compiled version was no longer working
properly.
Here is a update to extras/volume_id/*
o The device is now specified by the DEVPATH in the environment,
it's no longer needed to pass the major/minor to the callout.
o leading spaces and slashes are now removed from the returned string
and spaces are replaced by underscore, to not to confuse udev.
o Arnd Bergmann <arnd@arndb.de> provided the code to recognize s390
dasd disk labels. The -d switch tries to read the main block device
instead of the partition.

Here is a update, which supports iso9660 and udf labels.
Not very useful in the udev case, but I've added it for hal,
so we just catch up with the latest version.
here is a small udev toy, which enables udev to name partitions by
its filesystem label or uuid's.
The following udev rule:
KERNEL="sd*", PROGRAM="/sbin/udev_volume_id -M%M -m%m -u", SYMLINK="%c"
creates a symlink with the uuid read from the filesystem. If no label or
uuid is found the program exits with nonzero and the rule will fail.
ext2, ext3, reiserfs, xfs, jfs, vfat, msdos volume labels are supported,
ntfs and swap partitions can be recognized.
It's possible to compile with klibc and the static binary takes 13kb.
Here is the fix for extras/seliux/*
o install the binary in /sbin/
o add symlink to /etc/dev.d/ with suffix .dev
o removed the undefined udev_log variable
o fixed compiler warnings

Here we install the binary in /usr/sbin/ and symlink it to
/etc/dev.d/ with the .dev suffix.
It seems that the transition from DEVNODE to DEVNAME wasn't done
everywhere. This broke udev_dbus for me.
Attached patch does the transition in the places it wasn't done yet.
Hi, Greg. Appended is scsi-devfs.sh, a script for udev to implement
devfs-style names for SCSI hard discs, CD-ROM's and generic devices.
This has been tested with both hard discs and CD-ROM's. The SCSI
generic support should be OK for when there is sysfs/udev support for
SCSI generic devices. SCSI tapes are not yet implemented because I
don't have one to test with.
In addition, this script supports physical names, based on PCI bus
location, both longhand (/udev/bus/pci/...) and shorthand
(/udev/sd/pci/*).
