2005-04-26[PATCH] move udevinfo into the main build and clean up the main Makefile a bit.greg@kroah.com
2005-04-26[PATCH] udevinfo - now a real program :)kay.sievers@vrfy.org
I want to make udevinfo the standard query interface, so all the user features of the main udev are copied in here. It is now capable to: o query the database for a given value o dump the whole database o extract all possible device attributes for a sysfs_device In addition to the known options of udev it supports the query for the mode of the device node, and it includes the mode in the database dump: udevinfo -d P: /class/video4linux/video0 N: video/webcam0 M: 0666 S: camera0 kamera0 O: 500 G: 500 It is also a bit more friendly with the pathnames specified for devices or nodes. We remove the absolute path or add it if neccessary: udevinfo -q mode -n video/webcam0 udevinfo -q mode -n /udev/video/webcam0 0666 udevinfo -q mode -p /sys/class/video4linux/video0 udevinfo -q mode -p /class/video4linux/video0 udevinfo -q mode -p class/video4linux/video0 0666
2005-04-26[PATCH] udev - udevinfo with device chain walkkay.sievers@vrfy.org
udevinfo is now capable to print "all" attributes along the device chain of a sysfs device. Just like udev itself it walks the chain upwards and prints all usable attributes in the udev key format. So it should be easy to find unique attributes to compose a rule. All multiline attribute values and values containing non printable characters are skipped now. I hope nothing useful gets lost with this :) NOTE: The BUS value corresponding with the attributes is printed for every device. Don't specify BUS= in a rule and mix SYSFS_attributes from different busses, the rule can't match. ./udevinfo /sys/block/sda/sda1 device '/sys/block/sda/sda1' has major:minor 8:1 looking at class device '/sys/block/sda/sda1': SYSFS_dev="8:1" SYSFS_start="32" SYSFS_size="160" SYSFS_stat=" 0 0 0 0" follow the class device's "device" looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.3/1-1.3:1.0/host32/32:0:0:0': BUS="scsi" ID="32:0:0:0" SYSFS_detach_state="0" SYSFS_type="0" SYSFS_model="USB 2 HS-CF" SYSFS_vendor="SMSC " SYSFS_max_sectors="240" SYSFS_device_blocked="0" SYSFS_queue_depth="1" SYSFS_scsi_level="3" SYSFS_rev="1.25" SYSFS_online="1" looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.3/1-1.3:1.0/host32': BUS="" ID="host32" SYSFS_detach_state="0" looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.3/1-1.3:1.0': BUS="usb" ID="1-1.3:1.0" SYSFS_detach_state="0" SYSFS_bInterfaceNumber="00" SYSFS_bAlternateSetting=" 0" SYSFS_bNumEndpoints="02" SYSFS_bInterfaceClass="08" SYSFS_bInterfaceSubClass="06" SYSFS_bInterfaceProtocol="50" SYSFS_iInterface="00" looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.3': BUS="usb" ID="1-1.3" SYSFS_detach_state="0" SYSFS_bNumConfigurations="1" SYSFS_bNumInterfaces=" 1" SYSFS_bConfigurationValue="1" SYSFS_bmAttributes="80" SYSFS_bMaxPower=" 96mA" SYSFS_idVendor="0424" SYSFS_idProduct="20fc" SYSFS_bcdDevice="0125" SYSFS_bDeviceClass="00" SYSFS_bDeviceSubClass="00" SYSFS_bDeviceProtocol="00" SYSFS_speed="12" SYSFS_manufacturer="SMSC" SYSFS_product="USB 2 Flash Media Device" SYSFS_serial="0305037000C2" looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1': BUS="usb" ID="1-1" SYSFS_detach_state="0" SYSFS_bNumConfigurations="1" SYSFS_bNumInterfaces=" 1" SYSFS_bConfigurationValue="1" SYSFS_bmAttributes="e0" SYSFS_bMaxPower=" 64mA" SYSFS_idVendor="03eb" SYSFS_idProduct="3301" SYSFS_bcdDevice="0300" SYSFS_bDeviceClass="09" SYSFS_bDeviceSubClass="00" SYSFS_bDeviceProtocol="00" SYSFS_speed="12" SYSFS_product="Standard USB Hub" looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.0/usb1': BUS="usb" ID="usb1" SYSFS_detach_state="0" SYSFS_bNumConfigurations="1" SYSFS_bNumInterfaces=" 1" SYSFS_bConfigurationValue="1" SYSFS_bmAttributes="40" SYSFS_bMaxPower=" 0mA" SYSFS_idVendor="0000" SYSFS_idProduct="0000" SYSFS_bcdDevice="0206" SYSFS_bDeviceClass="09" SYSFS_bDeviceSubClass="00" SYSFS_bDeviceProtocol="00" SYSFS_speed="12" SYSFS_manufacturer="Linux 2.6.2-rc1-p4 uhci_hcd" SYSFS_product="UHCI Host Controller" SYSFS_serial="0000:00:1d.0" looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.0': BUS="pci" ID="0000:00:1d.0" SYSFS_detach_state="0" SYSFS_vendor="0x8086" SYSFS_device="0x2482" SYSFS_subsystem_vendor="0x1014" SYSFS_subsystem_device="0x0220" SYSFS_class="0x0c0300" SYSFS_irq="9" looking at the device chain at '/sys/devices/pci0000:00': BUS="" ID="pci0000:00" SYSFS_detach_state="0"

2005-04-26[PATCH] udev - small script optimizationkay.sievers@vrfy.org
Optimize the scripts reflecting the now more powerful rule logic, cause we can combine all known fields now in any order: The ide-devfs.sh is only executed if the kernel name matches with 'hd*': BUS="ide", KERNEL="hd*", PROGRAM="/etc/udev/ide-devfs.sh %k %b %n", NAME="%k", SYMLINK="%1c %2c" The name_cdrom.pl is only executed for ide and scsi devices, but not for a partition. It exits with nonzero to skip the rule if the CD is not found: KERNEL="[hs]d[a-z]", PROGRAM="name_cdrom.pl %M %m", NAME="%1c", SYMLINK="cdrom"

2005-04-26[PATCH] LSB init script and other stuffeike-hotplug@sf-tec.de
I had too much time during the holidays, so I played a bit with udev. The changes are like last time mostly on the init stuff. I'm sending you this as a great diff which is just for comments. What it does: -fix a typo in Makefile -use only one "grep -v" instead of many -don't include BK-Files into release (shrinks the stuff to 30%!) -add a new init script which is LSB compliant -add some flags to choose which one to use -use /etc/udev/udev.conf in Redhat init script as the source for the udev directory. If this is not done then the init script may create a directory which udev itself isn't using (I changed /udev to /Udev to avoid collisions with /usr and ran into this) -first check for sysfs_dir before creating udev_root (maybe someone else has already fixed this, I saw this discussion on lkml)
2005-04-26[PATCH] fix Silly udev scriptkay.sievers@vrfy.org
Hey, this is funny. I couldn't resist to give it a try and we need a few changes: - it's %2c otherwise nearly all my CD's are "good", but sure I also have bad ones :) - remove the node first, cause get_cddb() dies and leaves the old one there - remove spaces in name, cause this is our separator /udev/ |-- The_Cure-The_Peel_Sessions |-- cdrom -> ./The_Cure-The_Peel_Sessions |-- hda |-- hda1 |-- hda2 |-- hda4

2005-04-26[PATCH] experimental CALLOUT script for devfs ide node creation with cd, ↵kay.sievers@vrfy.org
disc, part Here is a experimental CALLOUT script for udev to create devfs nodes for IDE-devices. Not that I need these, I just wanted to see if it works :) The script is really stupid, no error handling, nothing more than absolutely needed. The rule uses the 'k' format char of the previous patch. The %D is not used, so the user can have disc or disk :) this single line: CALLOUT, BUS="ide", PROGRAM="/etc/udev/ide-devfs.sh %k %b %n", ID="hd*", NAME="%1c", SYMLINK="%2c" creates the following on my machine with two hard disks, one DVD and a PCMCIA-compact-flash inserted: /udev |-- hda |-- hda1 |-- hda2 |-- hda4 |-- hdb |-- hdb1 |-- hdc |-- hde |-- hde1 `-- ide |-- host0 | |-- bus0 | | |-- target0 | | | `-- lun0 | | | |-- disc -> ../../../../../hda | | | |-- part1 -> ../../../../../hda1 | | | |-- part2 -> ../../../../../hda2 | | | `-- part4 -> ../../../../../hda4 | | `-- target1 | | `-- lun0 | | |-- disc -> ../../../../../hdb | | `-- part1 -> ../../../../../hdb1 | `-- bus1 | `-- target0 | `-- lun0 | `-- cd -> ../../../../../hdc `-- host2 `-- bus0 `-- target0 `-- lun0 |-- disc -> ../../../../../hde `-- part1 -> ../../../../../hde1
2005-04-26[PATCH] libsysfs 0.4.0 patchdsteklof@us.ibm.com
Ananth released sysfsutils 0.4.0 last night, I'm sure you saw the email. Here's a patch with the latest changes from the pre-patch I already gave you. It includes sysfs_get_device_parent(), which you said you needed. I've run your test scripts and I've built scsi_id. Please play around with this and check it out. There are quite a few changes. Please do not access structure pointers, like sysfs_device's parent, directly like dev->parent. Please use the "get" function to retrieve. The functions load things on demand and refresh views under the covers.
2005-04-26[PATCH] fix scsi_id segfault with udev-009dsteklof@us.ibm.com
Scsi_id hasn't been changed to use the latest libsysfs changes. The "directory" in the sysfs_class_device is now considered "private" and only should be accessed using functions. Treating the structures as handles lets us only load information when it's needed, reducing caching or stale information and also helping performance. Here's the problem. static inline char *sysfs_get_attr(struct sysfs_class_device *dev, const char *attr) { return sysfs_get_value_from_attributes(dev->directory->attributes, attr); } Please try this quick fix:

* implement a reschedule flag in /var/run. Last thing the prog do before exit is check if a call to multipath was done (but canceled by /var/run/multipath.run check) during its execution. If so restart the main loop. * implement a blacklist of sysfs bdev to not bother with for now (hd, md, dm, sr, scd, ram, raw). This avoid sending SG_IO to unappropiate devices.

2005-04-26[PATCH] extras/multipath updatechristophe.varoqui@free.fr
here is the next update which brings this multipath to the state i'm not ashamed of it being in udev :) * drop a libdevmapper copy in extras/multipath; maybe discussions w/ Sistina folks will bring a better solution in the future. * drop a putchar usage in libdevmapper to compile cleanly with klibc * drop another such usage of my own in main.c * massage the Makefile to compile libdevmapper against klibc * use "ld" to produce the binary rather than "gcc -static" * stop being stupid w/ uneeded major, minor & dev in main.c:dm_mk_node() * reverse to creating striped target for now because the multipath target is more hairy than expected initialy * push the version code to 009 to be in synch w/ udev builds & run here. binary size is 43ko, which is fairly gratifying after all the efforts I've put to compiling it with klibc :)
2005-04-26[PATCH] udev-007/extras/multipath updatechristophe.varoqui@free.fr
here is a clean-up patch : * removes sg_err.[ch] deps * makes sure the core code play nice with klibc * port the sysfs calls to dlist helpers * links against udev's sysfs (need libsysfs.a & dlist.a) * finally define DM_TARGET as "multipath" as Joe posted the code today (not tested yet) * push version forward (do you want it in sync with udev version?) libdevmapper doesn't play well with klibc, so I wasn't able to produce a static binary yet. Help needed here ... as I don't want to fall back to merge libdevmapper code in the core. It compiles here and doesn't segfault.
