udev 129 says it supports linux 2.6.19 but prints a warning

Mikael Magnusson — 2008-10-03T20:33:11

I just updated udev to 129 and got this, udev: deprecated sysfs layout (CONFIG_SYSFS_DEPRECATED) is unsupported However, I have no such option in my kernel config (2.6.19). I assume this means 2.6.19 will soon not be supported in udev. It would perhaps be nice if the message said which kernel version would be required after the deprecation, and how far in the future this will happen?

udev doesn't detect ddf-format raid array

Peter — 2008-10-02T21:09:49

Hi! I have an adaptec hostraid controller (fakeraid) with 2 drives connected in a RAID1 array (metadata is in DDF format) which is nicely detected and enabled by dmraid, there is no problem with it after it's enabled. Recently debian's dmraid-booter has switched to use udev. But udev does not detect my drives as raid type, ID_FS_USAGE is missing from the drive info (it should be "raid"), so the result is that dmraid does not called at boot. Also vol_id sees the partitions as normal partitions. I've recognised that one of my disks has a HPA, the other hasn't. I'm not sure if this has any effect, but because of this, the DDF1-headers are not at the same position on the 2 drives. Below are some outputs. The last one is a 'dmraid -n' output, and what is strange for me at first sight is that both drives has 2 DDF1-headers. Is this normal? Or do you think I should try to rebuild the raid array with the bios utility (maybe after some bios upgrade)? Or is this rather an udev problem?

[PATCH] selinux: fix 'defined but not used' warning

udev-129 compile error with --disable-logging

Matthias Schwarzott — 2008-10-01T21:16:32

Hi there! It seems udev-129 has some log-related name conflicts when compiling udev configured with --disable-logging libudev-ctrl.c: In function 'udev_ctrl_enable_receiving': libudev-ctrl.c:104: error: called object 'log_null' is not a function libudev-ctrl.c: In function 'ctrl_send': libudev-ctrl.c:161: error: called object 'log_null' is not a function The original source is this: <<<<<<<<<<<<<<<<<<<<<< int udev_ctrl_enable_receiving(struct udev_ctrl *uctrl) { int err; const int feature_on = 1; err= bind(uctrl->sock, (struct sockaddr *)&uctrl->saddr, uctrl->addrlen); if (err < 0) { err(uctrl->udev, "bind failed: %m\n"); return err; } /* enable receiving of the sender credentials */ setsockopt(uctrl->sock, SOL_SOCKET, SO_PASSCRED, &feature_on, sizeof(feature_on)); return 0; } <<<<<<<<<<<<<<<<<<<<<< the pre-processor does change it to: <<<<<<<<<<<<<<<<<<<<<< int udev_ctrl_enable_receiving(struct udev_ctrl *uctrl) { int log_null; const int feature_on = 1; log_null= bind(uctrl->sock, (struct sockaddr *)&uctrl->saddr, uctrl->addrlen); if (log_null < 0) { log_null(uctrl->udev, "bind failed: %m\n"); return log_null; } setsockopt(uctrl->sock, 1, 16, &feature_on, sizeof(feature_on)); return 0; } <<<<<<<<<<<<<<<<<<<<<< So I think it will help to rename the err variable to any other name.

[ANNOUNCE] udev 129 release

Kay Sievers — 2008-10-01T20:47:11

Here comes a new udev version. Thanks to all who have contributed to this release. The tarball can be found here: ftp://ftp.kernel.org/pub/linux/utils/kernel/hotplug/ The development repository can be found here: http://www.kernel.org/git/?p=linux/hotplug/udev.git;a=summary The ChangeLog can be found here: http://www.kernel.org/git/?p=linux/hotplug/udev.git;a=blob;hb=HEAD;f=ChangeLog udev 129 ======== Fix recently introduced bug, which caused a compilation without large file support, where vol_id does not recognize raid signatures at the end of a volume. Firewire disks now create both, by-id/scsi-* and by-id/ieee-* links. Seems some kernel versions prevent the creation of the ieee-* links, so people used the scsi-* link which disappeared now. More libudev work. Almost all udevadm functionality comes from libudev now. udevadm trigger has a new option --type, which allows to trigger events for "devices", for "subsystems", or "failed" devices. The old option --retry-failed" still works, but is no longer mentioned in the man page. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo< at >vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH] Fix Linux RAID detection

Chris Spiegel — 2008-10-01T00:24:33

After upgrading to udev 128, the devices of my RAID array stopped being detected as such by vol_id. The reason is that libvolume_id lacks large file support, so it couldn't seek to the end of my 500GB devices to find the RAID magic. This patch simply #includes config.h in util.c so that the proper macros are defined, bringing in a 64-bit lseek(). If any other backends apart from Linux RAID require a volume_id_get_buffer() that has 64-bit support, they will obviously be fixed by this as well. diff -ru udev-128/extras/volume_id/lib/util.c udev-128.new/extras/volume_id/lib/util.c --- udev-128/extras/volume_id/lib/util.c2008-09-09 17:37:38.000000000 -0700 +++ udev-128.new/extras/volume_id/lib/util.c2008-09-30 15:55:19.402775372 -0700 < at >< at > -21,6 +21,7 < at >< at > #define _GNU_SOURCE 1 #endif +#include #include #include #include -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo< at >vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH] replace strerror() usage with threadsafe "%m" format string

Alan Jenkins — 2008-09-29T15:01:32

strerror() is not threadsafe. It uses a buffer to build messages of the form "Unknown error 387689". syslog() provides a %m format which is equivalent to strerror(errno). As a GNU extension, this is also accepted by printf and friends. At least in the current implementation, it is correctly threadsafe.

udev: bug in /lib/udev/path_id -- wrong assumptions about ieee1394 devices?

Stefan Richter — 2008-09-28T22:54:21

Hi, the path_id script was apparently written with the assumption that the hierarchy of IEEE1394 device representation begins with fw-host devices and ends with children (node entry devices) or grandchildren (unit directory devices) of them. If there are more levels of descendant devices than that, i.e. if there are children of unit directory devices, then path_id may get stuck with 100% CPU utilization. This is not a problem with current mainline drivers. But there is a new driver to be added soon which adds input devices which would naturally be children of unit directory devices. (It's the firedtv driver for FireDTV DVB devices which feature a remote control. See http://ieee1394.wiki.kernel.org/index.php/Out-of-tree_Kernel_Drivers and http://user.in-berlin.de/~s5r6/linux1394/firedtv/.) I will work around this path_id bug by making the input devices children of the fw-host devices. The drawback is that some useful information from the unit directory device and node entry device (like model, vendor, and unique ID) will be unavailable that way. Strangely, path_id does not hang due to the dvb child and dvb/* grandchildren of the node entry device. (I tested with Gentoo's udev-124-r1.) I hope that I won't need that workaround when I port firedtv from the ieee1394 stack to the firewire stack. The firewire stack does not have fw-host devices (only node entry devices and unit directory devices, with different names and attributes than in the ieee1394 stack), hence path_id's ieee1394 heuristics will not be triggered if the firewire stack is running. Just FYI.

[PATCH 0/2] udevd: Optimize "goto"

Alan Jenkins — 2008-09-28T11:00:29

I seem to remember you mentioned this as a longer-term goal. This was in the context of the TODO item "rework rules to a match-action list, instead of a rules array". The idea was to move the scan for the label targeted by a goto rule (udev_rules_iter_label), from run-time to parse-time. It avoids repeating the scan for every event. I already had a patch for this specific idea. I think it can be implemented now without causing problems. It's no big win - cachegrind suggests it takes 5% off user cpu time - but it is progress. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo< at >vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Differend udev names with different kernels

Tino Keitel — 2008-09-24T20:01:27

Hi, what's the intention of /dev/disk/by-id/? My firewire hard disk seems to have different names with different kernels. With 2.6.26.3, it's name is /dev/disk/by-id/ieee1394-0030e001e0006585:00043c:0000. With someting after 2.6.27-rc7, merged with Arjan's fastboot branch, the disk has the same name. With 2.6.27-rc7, it is called /dev/disk/by-id/scsi-1WDC_WD10EACS-00D6B0_WD-WCAU41668315. One major config difference is that 2.6.26.3 has CONFIG_FIREWIRE and CONFIG_FIREWIRE_SBP2 set to "m", whereas the 2.6.27 kernels have set them to "y". But that doesn't explain the difference between both 2.6.27-rc kernels. Shouldn't these names be somewhat constant? Otherwise they would be totally useless.

Polish manual translation for udevadm

Hi, are you interested in appending to udev package the Polish translation of man udevadm? I attached *roff and docbook versions of man for udev-128, both in UTF-8, but I can't give command for proper encoding (manpage from docbook version have missing Polish chars like "ł" or ó"), see diferent both manpages.

ntfs.c failure in udev128

Scott Tester — 2008-09-18T01:34:59

I am having problems with udev recognizing an ntfs filesystem under udev128. Strangly, another ntfs partition is being recognized. (One formatted using mkfs.ntfs.) (I have added extra info() lines to ntfs.c and util.c as my syslog config is not picking up debug statements.)

Is there a bug manager for udev?

lvm+dmsetup device mapper rules

Michal Soltys — 2008-09-17T12:35:35

This is an attempt at generic device mapper rules file. Both lvm and manually (dmsetup) created devices are supported. The rules file depends only on lvm and dmsetup binaries. Standard /dev/disk/* symlinks are created at the end, with additional /dev/disk/by-id/dm-uuid-* symlinks (by device's uuid, not filesystem's one). KERNEL=="device-mapper", NAME="mapper/control", GOTO="dm_end" ACTION!="add|change", GOTO="dm_end" SUBSYSTEM!="block", GOTO="dm_end" KERNEL!="dm*", GOTO="dm_end" # First get the name from dmsetup - it can be fed to lvs for parsing PROGRAM="/sbin/dmsetup info -c --noheadings -o name -j%M -m%m", ENV{DM_NAME}="%c" ENV{DM_NAME}!="?*", GOTO="dm_end" ENV{DM_NAME}=="?*", NAME="mapper/$env{DM_NAME}" # Try to get volume group name # - lvs always indents first field with 2 spaces (thus %c{2}) # - note, that node doesn't have to exist, and it would fail if $tempnode was used PROGRAM="/sbin/lvm lvs --ignorelockingfailure --noheadings -o vg_name /dev/mapper/$env{DM_NAME}", ENV{LVM_VGN}="%c{2}" ENV{LVM_VGN}!="?*", GOTO="dm_finalize" PROGRAM="/sbin/lvm lvs --ignorelockingfailure --noheadings -o lv_name /dev/mapper/$env{DM_NAME}", ENV{LVM_LVN}="%c{2}" ENV{LVM_LVN}!="?*", GOTO="dm_finalize" SYMLINK+="$env{LVM_VGN}/$env{LVM_LVN}" LABEL="dm_finalize" # /disk/* symlinks PROGRAM="/sbin/dmsetup info -c --noheadings -o uuid -j%M -m%m", SYMLINK+="disk/by-id/dm-uuid-%c" IMPORT{program}="vol_id --export $tempnode" ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{ID_FS_UUID_ENC}=="?*", SYMLINK+="disk/by-uuid/$env{ID_FS_UUID_ENC}" ENV{ID_FS_USAGE}=="filesystem|other", ENV{ID_FS_LABEL_ENC}=="?*", SYMLINK+="disk/by-label/$env{ID_FS_LABEL_ENC}" LABEL="dm_end"

udev-test.pl failures

commit 8753fadf2a6ecead372e71b8bf9336cf29f9c958 Author: Kay Sievers vrfy.org> Date: Mon Sep 15 17:12:47 2008 -0700 libudev: switch API from devpath to syspath Lots of the udev tests fail here. udev_sysfs.c broke when util_resolve_sys_link() switched API. I'll leave this up to you - maybe your next commit is going to do away with udev_sysfs.c altogether :-).
