HAL soon wants to read the whole content of the udevdatabase while starting up. This makes the whole udev structure available to the udevinfo "dump". Signed-off-by: Kay Sievers <kay.sievers@suse.de>

2005-06-06Fix udevinfo for empty sysfs directoriesGreg KH
udevinfo would die if it ran into a sysfs directory with no attributes. This is valid for a lot of scsi devices, so now we just continue on up the chain. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2005-04-26[PATCH] replace tdb database by simple lockless file databasekay.sievers@vrfy.org
This makes the udev operation completely lockless by storing a file for every node in /dev/.udevdb/* This solved the problem with deadlocking concurrent udev processes waiting for each other to release the file lock under heavy load.
2005-04-26[PATCH] big cleanup of internal udev apikay.sievers@vrfy.org
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.
2005-04-26[PATCH] close the syslogkay.sievers@vrfy.org
Seems that we never closed the opened syslog. Here is a patch to do this in all our binaries.
2005-04-26[PATCH] netdev - udevdb+dev.d changeskay.sievers@vrfy.org
Here is a patch to change the netdev handling in the database and for the dev.d/ calls. I applies on top of the udevd.patch, cause klibc has no sysinfo(). o netdev's are also put into our database now. I want this for the udevruler gui to get a list of all handled devices. All devices in the db are stamped with the system uptime value at the creation time. 'udevinfo -d' prints it. o the DEVPATH value is the key for udevdb, but if we rename a netdev, the name is replaced in the kernel, so we add the changed name to the db to match with the remove event. NOTE: The dev.d/ scripts still get the original name from the hotplug call. Should we replace DEVPATH with the new name too? o We now only add a device to the db, if we have successfully created the main node or successfully renamed a netdev. This is the main part of the patch, cause I needed to clean the retval passing trough all the functions used for node creation. o DEVNODE sounds a bit ugly for netdev's so I exported DEVNAME too. Can we change the name? o I've added a UDEV_NO_DEVD to possibly skip the script execution and used it in udev-test.pl. udevstart is the same horror now, if you have scripts with logging statements in dev.d/ it takes minutes to finish, can we skip the scripts here too? o The get_device_type() function is changed to be more strict, cause 'udevinfo -a -p /block/' gets a class device for it and tries to print the major/minor values. o bugfix, the RESULT value has now a working newline removal and a test for this case.
2005-04-26[PATCH] hmm, handle net devices with udev?kay.sievers@vrfy.org
Hmm, Arndt Bergmann sent a patch like this one a few weeks ago and I want to bring the question back, if we want to handle net device naming with udev. With this patch it is actually possible to specify something like this in udev.rules: KERNEL="dummy*", SYSFS{address}="00:00:00:00:00:00", SYSFS{features}="0x0", NAME="blind%n" KERNEL="eth*", SYSFS{address}="00:0d:60:77:30:91", NAME="private" and you will get: [root@pim udev.kay]# cat /proc/net/dev Inter-| Receive | Transmit face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed lo: 1500 30 0 0 0 0 0 0 1500 30 0 0 0 0 0 0 private: 278393 1114 0 0 0 0 0 0 153204 1468 0 0 0 0 0 0 sit0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 blind0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 The udevinfo program is also working: [root@pim udev.kay]# ./udevinfo -a -p /sys/class/net/private looking at class device '/sys/class/net/private': SYSFS{addr_len}="6" SYSFS{address}="00:0d:60:77:30:91" SYSFS{broadcast}="ff:ff:ff:ff:ff:ff" SYSFS{features}="0x3a9" SYSFS{flags}="0x1003" SYSFS{ifindex}="2" SYSFS{iflink}="2" SYSFS{mtu}="1500" SYSFS{tx_queue_len}="1000" SYSFS{type}="1" follow the class device's "device" looking at the device chain at '/sys/devices/pci0000:00/0000:00:1e.0/0000:02:01.0': BUS="pci" ID="0000:02:01.0" SYSFS{class}="0x020000" SYSFS{detach_state}="0" SYSFS{device}="0x101e" SYSFS{irq}="11" SYSFS{subsystem_device}="0x0549" SYSFS{subsystem_vendor}="0x1014" SYSFS{vendor}="0x8086" The matching device will be renamed to the given name. The device name will not be put into the udev database, cause the kernel renames the device and the sysfs name disappears. I like it, cause it plugs in nicely. We have all the naming features and sysfs queries and walks inside of udev. The sysfs timing races are already solved and the management tools are working for net devices too. nameif can only match the MAC address now. udev can match any sysfs value of the device tree the net device is connected to. But right, net devices do not have device nodes :)
2005-04-26[PATCH] udevinfo patchdsteklof@us.ibm.com
I think this is what you want for udevinfo. Patched against the latest BK tree. I tested it and it seemed to work. One other question, shouldn't udevinfo.c:print_all_attributes() check to make sure attr->method is SYSFS_METHOD_SHOW along with checking to see if attr->value != NULL or doesn't that matter? Here's the libsysfs fix for print_device_chain():

The device list is sorted in alphabetical order now and if there are only a few recently discovered devices, they are placed on top of the list. For those who want to have a look: http://vrfy.org/projects/udev/udevruler.png The patch applies on top of today's mmap() patch. The db format is changed to have the file and line number of the applied rule. So it should be easy to edit the matching rule with this beast. It compiles with "make all udevruler".
