2005-04-26[PATCH] make symlink work properly if there is already a file in its placeazarah@nosferatu.za.org
If a file that is not a symlink (node, socket, fifo, etc) already exist where udev need to create a symlink, symlink() fails. This patch basically test for an existing file, and unlink it.
2005-04-26[PATCH] check for empty symlink stringkay.sievers@vrfy.org
Attached is a patch for udev-add.c to ignore empty symlink string parts. Issue was brought up by ide-devfs.sh with only one symlink returned, while two are expected.
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] pre-libsysfs-0.4.0 patchdsteklof@us.ibm.com
I am sending you a pre-release patch. It's everything that's in our current CVS tree. It adds the functionality you've been looking for. Please play with this before checking it into your tree, I'd like to know if it's ok with you or if you find problems. I have tested this out with test.all and the perl regression test. Let me know what you think. Still need to do more testing for our work and add some more functions related to the changes. I've gone into namedev.c and udev-add.c to make the necessary changes in line with the library. I have not gone and edited any of the "extras". Changes: 1) Libsysfs object structures work more as handles now, their included directories or devices are labeled private. If you need attributes from a sysfs_class_device, call the available function and don't access the directory directly. Same holds true for a sysfs_class_device sysfs_device. Do not access the link directly but call the function sysfs_get_classdev_device() instead. We only populate entries upon request, makes things faster and uses less memory. 2) Added sysfs_get_classdev_parent() as requested. 3) Changed getpagesize to sysconf. 4) Added sysfs_refresh_attributes function for refreshing views of attribute lists. We still need to add refresh for links and subdirs. All udev needs to do is keep calling sysfs_get_classdev_attr() and that will internally call the refresh routine.
2005-04-26[PATCH] allow multiple symlinkskay.sievers@vrfy.org
Here is a patch to allow the creation of multiple symlinks. The names must be separated by a space character. REPLACE, KERNEL="ttyUSB0", NAME="visor", SYMLINK="first-%n second-%n third-%n" results in: Dec 9 05:28:51 pim udev[12019]: create_node: mknod(udev-root/visor, 020666, 188, 0) Dec 9 05:28:51 pim udev[12019]: create_node: symlink 'udev-root/first-0' to node 'visor' requested Dec 9 05:28:51 pim udev[12019]: create_node: symlink(./visor, udev-root/first-0) Dec 9 05:28:51 pim udev[12019]: create_node: symlink 'udev-root/second-0' to node 'visor' requested Dec 9 05:28:51 pim udev[12019]: create_node: symlink(./visor, udev-root/second-0) Dec 9 05:28:51 pim udev[12019]: create_node: symlink 'udev-root/third-0' to node 'visor' requested Dec 9 05:28:51 pim udev[12019]: create_node: symlink(./visor, udev-root/third-0)

2005-04-26[PATCH] D-BUS patch for udev-008david@fubar.dk
Attached is a patch against udev-008 to send out a D-BUS message when a device node is added or removed. Using D-BUS lingo, udev acquires the org.kernel.udev service and sends out a NodeCreated or NodeDeleted signal on the org.kernel.udev.NodeMonitor interface. Each signal carries two parameters: the node in question and the corresponding sysfs path. [Note: the D-BUS concepts of service, interface, object can be a bit confusing at first glance] An example program listening for these messages looks like this #!/usr/bin/python import dbus import gtk def udev_signal_received(dbus_iface, member, service, object_path, message): [filename, sysfs_path] = message.get_args_list() if member=='NodeCreated': print 'Node %s created for %s'%(filename, sysfs_path) elif member=='NodeDeleted': print 'Node %s deleted for %s'%(filename, sysfs_path) def main(): bus = dbus.Bus(dbus.Bus.TYPE_SYSTEM) bus.add_signal_receiver(udev_signal_received, 'org.kernel.udev.NodeMonitor', # interface 'org.kernel.udev', # service '/org/kernel/udev/NodeMonitor') # object gtk.mainloop() if __name__ == '__main__': main() and this is the output when hot-plugging some usb-storage. [david@laptop udev-008]$ ~/node_monitor.py Node /udev/sda created for /block/sda Node /udev/sda1 created for /block/sda/sda1 Node /udev/sda1 deleted for /block/sda/sda1 Node /udev/sda deleted for /block/sda The patch requires D-BUS 0.20 or later while the python example program requires D-BUS from CVS as I only recently applied a patch against the python bindings.

2005-04-26[PATCH] udev: sleep_for_dev() bitsrml@tech9.net
OK, I fixed that bug you hinted at earlier in my previous sleep_for_dev() patch. I am sure you fixed it, but here we go nonetheless, just in case. I actually changed it up a bit. It is probably faster to count down from SECONDS_TO_WAIT_FOR_DEV than count up. I also made the lone 'path' argument const, since it can be. Some other misc. bits, too.

2005-04-26[PATCH] udevdb prototypedsteklof@us.ibm.com
Here's an "idea" of what I had in mind for udevdb. Let me preface the code with a few remarks: 1) I was expecting to write this udevdb for udev to keep track of devices. I was planning an external package that depends upon udev to provide an external API to the udevdb database. The calls for the interface would be read only access. Not sure how you want to do packaging, if having a separate package is ok or having it included in udev. 2) I created it as it is because udev isn't a daemon. So, the open database call doesn't take any parameters. My plan was to create a udevdb_init function that took arguments for initializing the db to start, where you could specify in memory only or a file location. This can all be filled in. 3) I hacked the Makefile to get it to work. Not sure how you'd want that in the future. 4) This assumes TDB has been installed elsewhere, you would need to edit your Makefile and point it to the header and library locations. How do you want to do TDB in udev? Do you want to just reference it and make udev dependent on that package being installed. Or should we do what samba does and include a limited tdb version in udev? 5) Again, I hacked udev into your existing code. In the future, I'd probably make a function around the filling out the udevice before calling the store command. Didn't know if you wanted to change your add device function to use struct udevice rather than having everything separate. 6) Not sure what we should include in the udevice structure that's stored by udev. I made a stab at a first shot - we can add and remove of course, this was a first pass. I've come to realize - with you including libsysfs in udev, the "external" interface that references udevdb could make use of getting information from through libsysfs from sysfs and doesn't need to be in udevdb. 7) I could write a namedevdb for namedev's device management if you wanted.
