2005-04-26[PATCH] remove sleeps from udev as it is external nowkay.sievers@vrfy.org
Here we remove all the sysfs sleep loops from udev as wait_for_sysfs will do this for us and any other hotplug user. We still keep a small blacklist of subsystems we don't care about but any missing entry here will no longer lead to a spinning udev waiting for files.
2005-04-26[PATCH] prevent deadlocks on an corrupt udev databasekay.sievers@vrfy.org
Here is the patch, that should prevent all of the known deadlocks with corrupt tdb databases we discovered. Thanks to Frank Steiner <fsteiner-mail@bio.ifi.lmu.de>, who tested all this endlessly with a NFS mounted /dev. The conclusion is, that udev will not work on filesystems without proper record locking, but we should prevent the endless loops anyway. This patch implements: o recovery from a corrupted udev database. udev will continue without database support now, instead of doing nothing. So the node should be generated in any case, remove will obviously not work for custom names. o added iteration limits to the tdb-code at the places we discovered endless loops. In the case tdb tries to find more than 100.000 entries with the same hash, we better give up :) o prevent a {all_partitions} loop caused by corrupt db data o log all tdb errors to syslog o switch sleep() to usleep() cause we want to use alarm()
2005-04-26[PATCH] switch udev's seqnum to u64kay.sievers@vrfy.org
The kernel will use a u64 for the sequence number, so we want the same.

We may just test if we are there > instead of the "device" match. How about something like this. It adds all the net devices without looking at the attributes and keeps the remaining logic like it is. It also removes certain levels of indirection and much simplifies the udevstart process. We surely don't need to open and close the udevdb for every node while iterating over the list. (We are about 5% faster on my box) It's not well tested, so it would be nice if someone can have a look at it, before a broken udevstart renders any system unbootable.
2005-04-26[PATCH] udev - read long lines from config files overflow fixarun@codemovers.org

While looking at it I restructured > the buffer reading logic a bit and fixed another stupid bug. Thanks for the cleanup. You may have overlooked the fix for udev_config.c(parsing udev.conf) in your patch. So, I've adapted the fixes you applied to namedev_parse.c to this file also. Also, while 'eating' the whitespace the 'count' doesn't get decremented. This leads strncpy to copy the number of whitespace minus 1 characters from the next line. Minus 1 because it copies '\n' from the current line. while (isspace(bufline[0])) { bufline++; + count--; } . . . strncpy(line, bufline, count); Included patch(against udev-030) contains the above fixes as well as your fixes.

2005-04-26[PATCH] pass SEQNUM trough udevdkay.sievers@vrfy.org
here we change udevd to pass the SEQNUM from the hotplug environment to udev and the dev.d/ scripts. We need this for HAL to match the hotplug event with the dev.d/ events. It also changes the type from int to long to match the kernel.
2005-04-26[PATCH] Make udev/udevstart be one binarytrini@kernel.crashing.org
Hi, The following patch makes udev/udevstart be a common binary. First, doing this grows udev by a total of 1.8kB (ppc32, stripped) whereas udevstart by itself is 6.4kB. I know you mentioned being able to replace udevstart with a script, but at 1.8kB I don't think it'll be easy to beat this with size there. Next, the following are by-eye timings of before, after, and with devfs on a slow, but still usable embedded platform (config stripped down to more-or-less bare for ramdisk): -- Embedded Planet RPX LITE, 64Mhz MPC 823e -- devfs : 15.333s, 15.253s, 14.988s (15.191s avg) udev-pristine : 18.675s, 18.079s, 18.418s (18.390s avg) udev-multi : 14.587s, 14.747s, 14.868s (14.734s avg) The patch ends up being rather large to add this, as in doing so I ended up making all refs (that I hit..) to devpath/subsystem be marked as 'const'.

2005-04-26[PATCH] DEVPATH for netdevkay.sievers@vrfy.org
Here we change the DEVPATH for netdev's in the environment of the dev.d/ scripts to the name the device is renamed to. The original name doesn't exist in the kernel after rename.
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.

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".

2005-04-26[PATCH] replace fgets() with mmap() and introduce udev_lib.[hc]kay.sievers@vrfy.org
Here we replace the various fgets() with a mmap() call for the config file reading, due to the reported performance problems with klibc. Thanks to Patrick's testing, it makes a very small, close to nothing speed gain for libc users, but a 6 times speed increase for klibc users with a 1000 line config file. I've created a udev_lib.[hc] for this and also moved all the generic stuff from udev.h in there and uninlined the functions.
2005-04-26[PATCH] rename strn*() macros to strmaxkay.sievers@vrfy.org
Hey, I wrote the strn*() macros just 10 days ago and yesterday this trap caught me with the %c{x} bug. The names are misleading cause we all expect that the from field is limited by the size argument, but we actually limit the overall size of the destination string to prevent a overflow. Here we rename all strn*() macros to str*max(). That should be more self-explanatory.

2005-04-26[PATCH] cleanup mult field string handlingkay.sievers@vrfy.org
Here I try to cleanup our various multifield iteration over the strings. Inspired by our nice list.h we now have a macro to iterate over the string and process the parts of it: It makes the code more readable and we don't change the string while we process it like the former strsep() does. Example: foreach_strpart(dev->symlink, " ", pos, len) { if (strncmp(&dev->symlink[pos], find_name, len) != 0) continue; ... } For the callout part selector %c{2} we separate now not only by space but also newline and return characters, cause some programs may give multiline values back. A possible RESULT match must contain wildcards for these characters. Also a bug in the recent udevinfo symlink query feature is fixed.
2005-04-26[PATCH] udev - safer sprintf() usekay.sievers@vrfy.org
Here is for now my last patch to the string handling for a rather theorethical case, where the node is very very very long. :) We have accordant to strfieldcat(to, from) now a strintcat(to, i) macro, which appends the ascii representation of a integer to a string in a safe way.
2005-04-26[PATCH] udev - safer string handling - part fourkay.sievers@vrfy.org
Mainly a cleanup of the earlier patches with a few missing pieces and some cosmetical changes. I've moved the udev_init_config() to very early init, otherwise we don't get any logging for the processing of the input. What would I do without gdb :) Greg, it's the 7th patch in your box to apply. I will stop now and wait for you :)
2005-04-26[PATCH] udev - safer string handling - part threekay.sievers@vrfy.org
Here we truncate our input strings from the environment to our defined limit. It's a bit theroretical but better check for it. It cleans up some magic length definitions and removes the code duplication in udev, udevtest and udevsend. udevd needs to be killed after installation, cause the message size is changed with this patch. Should we do this with the 'make install', like we do with the '.udevdb'?
2005-04-26[PATCH] udev - safer string handling - part twokay.sievers@vrfy.org
As promised, here is the next round. We provide in addition to the already used macros: strfieldcpy(to, from) strfieldcat(to, from) the corresponding friends, if the size of the target is not known and must be provided by the caller: strnfieldcpy(to, from, maxsize) strnfieldcat(to, from, maxsize) and switch nearly all possibly unsafe users of strcat(), strncat(), strcpy() and strncpy() to these safer macros. The last known remaining issue seems the use of sprintf() and snprintf(). I will take on it later today or tomorrow.

2005-04-26[PATCH] make logging a config optionazarah@nosferatu.za.org
Once again, patch to make logging a config option. Reason for this (since you asked for it): - In our setup it is easy (although still annoying) .. just edit the ebuild, add logging support (or remove it) and rebuild. For say a binary distro, having the logging is useful for debugging some times, but its more a once of, or rare thing, as you do not add or change config files every day. Sure, we can have logging by default, but many do not want ~300 lines of extra debugging in their logs is not pleasant, and they will complain. Rebuilding the package for that binary package (given the users it is targeted to) is usually not within most users grasp.

2005-04-26[PATCH] set default owner/group in db.hannal@us.ibm.com
This patch fixes a bug where the udev database stored empty strings for Owner and Group if they were default. This patch stores the default value into the database if not set otherwise. See example output: crw------- 1 root root 4, 65 Jan 16 11:13 ttyS1 P: /class/tty/ttyS1 N: ttyS1 S: O: root G: root This is a bit of a hack. However, until udev supports setting the o/g values they will be root/root anyway so the database might as well reflect the truth instead of empty strings.

I've created a logging.h file and moved the debug macros from udev.h in there. If you type: 'make' - you will get a binary that prints one or two lines to syslog if a device node is created or deleted 'make LOG=false' - you get a binary that prints asolutely nothing 'make DEBUG=true' - the same as today, it will print all debug lines

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.

2005-04-26[PATCH] enable default_mode ability to actually buildgreg@kroah.com
2005-04-26[PATCH] get rid of the majority of the debug environment variables.greg@kroah.com
Now there are only 3 valid environment test variables. The rest can be specified with the config file.
2005-04-26[PATCH] add support for a main udev config file, udev.conf.greg@kroah.com
the older udev.config file is now called udev.rules. This allows us to better control configuration values, and move away from the environment variables.
2005-04-26[PATCH] Build failure - missing linux/limits.h include?arnd@arndb.de

No, don't include kernel headers directly if you can avoid it. The problem you are referring to seems to be with old tool chains, I have the same symptom with my s390 gcc-2.95/glibc-2.1.3. Including <sys/param.h> instead of <limits.h> seems to fix it.
2005-04-26[PATCH] changed the default location of the database to /udev/.udev.tdb to ↵greg@kroah.com
be LSB compliant Finally the Debian people can get off my back...
2005-04-26[PATCH] overall whitespace + debug text conditioningkay.sievers@vrfy.org
01-overall-whitespace+debug-text-conditioning.diff o cleanup whitespace o clarify a few comments o enclose all printed debug string values in ''
2005-04-26[PATCH] added ability to put format specifiers in the CALLOUT program string.greg@kroah.com
2005-04-26[PATCH] more robust config file parsing in namedev.carnd@arndb.de
After getting a number of different crashes for udev reading broken udev.config files, I decided to try to make the parser a little more robust. The behaviour is changed to stop reading the configuration file and logging the broken entry instead of silently ignoring it (is that good? It's easy to just print and continue). All strcpy()'s to a fixed length string are now implicitly limited to the bounds of the target string. I kept the -ENODEV return code for now, not sure if there should be different ones.
2005-04-26[PATCH] got rid of struct device_attrgreg@kroah.com
namedev.c is still a mess, that's up next after testing...
2005-04-26[PATCH] rename namedev.permissions and namedev.config to udev.permissions ↵greg@kroah.com
and udev.config the namedev name didn't really make much sense anymore...
2005-04-26[PATCH] make config files, sysfs root, and udev root configurable from ↵greg@kroah.com
config variables This will make running tests a lot simpler.
2005-04-26[PATCH] major database cleanupsgreg@kroah.com
Now we standardise on a struct udevice to pass around, and store in the database. This cleaned up the database code a lot.
