We are already using %u in the sscanf() format string.
The patch replaces the int for the kernel release number with
unsigned int, as we can never have negative release numbers.
First case without the patch:
KERNEL="hd*", GROUP="disk", MODE="0660"
KERNEL="hdc", SYMLINK="cdrecorder", MODE="0666"
brw-rw---- 1 root disk 22, 0 Feb 5 14:08 /dev/hdc
Second case without the patch:
KERNEL="hd*", GROUP="disk", MODE="0660"
KERNEL="hdc", MODE="0666"
brw-rw-rw- 1 root disk 22, 0 Feb 5 14:08 /dev/hdc
Adding prototypes for functions resulted in an error, cause:
table_find_disk(disk_snum, &chassis_num, &slot_num);
is called but the function is defined as:
int table_find_disk(char *serialnumber , int *host_num, int *chassis_num, int *slot_num)
which can obviously not work correctly.
Using popen() is not klibc compatible, so skip the compilation if
a klibc compile is requested.
Move code into a .c-file instead of big inline functions in a header file.
Pass the device name down instead of relying that the node name is equal
to the kernel name.
The -d option in udev_allows to go from a partition to the underlying disk
for s390 dasd labels. If the device is already the disk itself, finding the
parent will fail, therefore -d on /sys/block/dasda/ for example gives no
result at all.
If the system reaches a defined limit of processes in running state, udevd
starts to count its own processes in running state from its session (all
forked hotplug child processes, subprocesses and callouts) and throttles
further process forking if the limit is reached.
This should help setups with hundreds of events emitted hotplug events
in parallel with hundreds of processes in "R" state. which makes the machine
unresponsible.
I placed a 100% cpu time consuming program in /etc/hotplug.d/ which runs for 5
seconds. With this patch I can load "scsi_debug add_host=100" without any major
problem. Without the patch the box is completly unresponsible for many minutes.
Fix FAT label reading bug for very large volumes.
Recognize FAT label at Win98 formatted volumes.
Read iso9660 joliet descriptor for unicode labels.
Support uuid/label of swap partitions.
We delay the execution of events if there is already an event running for
the same device, a parent or a child device. "add" events with a reference
to a physical device will also wait for the physical device to finish.
Here we fix the devpath comparison logic to return "busy" only if a complete
device names is matching. /block/sdaa will not longer block a /block/sda event.
Define an inititialization phase, where we delay the events only
for a short time to eventually recollect the event sequence instead
of delaying the very first events for 10 seconds, which breaks the
firmware loader.
With the "permissions only rules" we can just place:
MODE="0660", OWNER="root", GROUP="root"
at the beginning of the rules file and get exactly the same behavior.
If no values are given the compiled-in defaults are used.

If we take over the hotplug call and manage the events we don't need
to call the event fake script in dev.d/. Just set all expected values
to the new network interface name and call hotplug.d/. This way the
device renaming is completely handled inside of udev and userspace
can't get confused.
