2005-04-26[PATCH] ide-devfs.sh updatekay.sievers@vrfy.org
Attached is a patch for ide-devfs.sh, The script is merged with the one from Martin Schlemmer, and cleaned up by him, to create both types of symlinks with one single rule: CALLOUT, BUS="ide", PROGRAM="/etc/udev/ide-devfs.sh %k %b %n", ID="hd*", NAME="%1c", SYMLINK="%2c %3c" /udev/ |-- cdroms | `-- cdrom0 -> ../hdc |-- discs | |-- disc0 | | |-- disc -> ../../hda | | |-- part1 -> ../../hda1 | | |-- part2 -> ../../hda2 | | `-- part4 -> ../../hda4 | |-- disc1 | | |-- disc -> ../../hdb | | `-- part1 -> ../../hdb1 | `-- disc2 | |-- disc -> ../../hde | `-- part1 -> ../../hde1 |-- 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] extras multipath updatechristophe.varoqui@free.fr
incremental to 20031222-2, 2003-12-22 multipath-010 * tweak the install target in Makefile * stop passing fds as argument : this change enable a strict segregation of ugly 2.4 code * sysfs version of get_lun_strings() * be careful about the return of get_unique_id() since errors formerly caught up by if(open()) in the caller fn are now returned by get_unique_id() * send get_serial() in unused.c
2005-04-26[PATCH] extras multipath updatechristophe.varoqui@free.fr
incremental to 20031222, 2003-12-22 multipath-010 * introduce dm-simplecmd for RESUME & SUSPEND requests * split add_map() in setup_map() & dm-addmap() * setup_map() correctly submits "SUSPEND-RELOAD-RESUME or CREATE" sequences instead of the bogus "RELOAD or CREATE"
2005-04-26[PATCH] extras multipath updatechristophe.varoqui@free.fr
incremental to 20031220, 2003-12-22 multipath-010 * don't print .sg_dev if equal to .dev (2.6) in print_path() * since the kernel code handles defective paths, remove all code to cope with them : * move do_tur() to unused.c * remove .state from path struct * remove .state settings & conditionals * add a cmdline switch to force maps to failover mode, ie 1 path per priority group * add default policies to the whitelist array (spread io == MULTIBUS / io forced to 1 path == FAILOVER) * move get_disk_size() call out of add_map() to coalesce() * comment tricky coalesce() fn * bogus unsused.c file renamed to unused.c
2005-04-26[PATCH] extras multipath updatechristophe.varoqui@free.fr
An important one, against stock udev-009 : 2003-12-20 multipath-010 * big ChangeLog update * start to give a little control over target params : introduce cmdline arg -i to control polling interval * cope with hotplug-style calling convention : ie "multipath scsi $DEVPATH" ... to avoid messing with online maps not concerned by an event * example hotplug agent to drop in /etc/hotplug.d/scsi * revert the run & resched patch : unless someone proves me wrong, this was overdesigned * move commented out functions in unused.c * update multipath target params to "udm[23] style" * mp target now supports nr_path == 1, so do we * add gratuitous free() * push version forward
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:
2005-04-26[PATCH] more extras/multipath changeschristophe.varoqui@free.fr
* Make the HW-specific get_unique_id switch pretty * Prepare to field-test by whitelisting all known fibre array, try to fetch WWID from the standard EVPD 0x83 off 8 for everyone ... we will learn from feedback :) Could you drop a note with the udev-009 release-notes asking for testing this WWID fetching thing ?
2005-04-26[PATCH] and more extras/multipath updateschristophe.varoqui@free.fr
* configure the multipath target with round-robin path selector and conservative default for a start : yes it makes this release the first really useful one. * temporarily disable map creation for single path device due to current restrictive defaults in the kernel target. Sistina should work it out. * correct the strncmp logic in blacklist function.

2005-04-26[PATCH] more extras/multipath updateschristophe.varoqui@free.fr
* update the Makefiles to autodetect libgcc.a & gcc includes "ulibc-style". Factorisation of udevdirs & others niceties * drop a hint about absent /dev/sd? on failed open() for poor Debian users who don't imagine their favorite distro with only 16 preconfigured SCSI device nodes :)
2005-04-26[PATCH] update udev extras/scsi_id to version 0.2patmans@us.ibm.com
This patch updates scsi_id under udev from version 0.1 to version 0.2.
2005-04-26[PATCH] yet more extras/multipathchristophe.varoqui@free.fr
* 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. Compiles & survive "while true;do (./multipath -v &);done"
2005-04-26[PATCH] more extras/multipath updateschristophe.varoqui@free.fr
* Adds a /var/run/multipath.run handling to avoid simultaneous runs. * Remove a commented-out "printf"
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.
