Some rules do not work in udev 131 and 132

Some rules do not work in udev 131 and 132

[Mikhail Kolesnik]

Hello.
 
udev was built from sources with no patching or very special rulesets
installed. After a simple update from 130 to 131 some of my custom rules
stopped working. And I can't find information about syntax change in
git log.

In the example below the first rule creates a symlink, but the second
one creates none. It works with 130 but does not work on 131 and 132.
The same results for another device (and partitions are there
untouched).

BUS="usb", ATTRS{serial}="A500000000025423", KERNEL="sd?", NAME="%k", SYMLINK+="usbflash", GROUP="cdrom"
BUS="usb", ATTRS{serial}="A500000000025423", KERNEL="sd?[1-3]", NAME="%k", SYMLINK+="usbflash%n", GROUP="cdrom"

These rules seem to work fine here. I just replaced the serial number:
  ls -l /dev/usbflash*
  lrwxrwxrwx 1 root root 3 Nov 12 21:21 /dev/usbflash -> sdb
  lrwxrwxrwx 1 root root 4 Nov 12 21:21 /dev/usbflash1 -> sdb1

What does (replace sdb with the correct name):
  udevadm test /class/block/sdb
  udevadm test /class/block/sdb1
print?

I get "unable to open device '/class/block/sd*'" for
any '/class/block/sd*' name. The same for "/block/sd*[0-9]":

# udevadm test /block/sdc1
run_command: calling: test

Only names like '/block/sdX' seems to go beyond the parse_file part:

Your kernel has the old sysfs layout. Put the  partition devices after
the disk device:
  udevadm test /block/sdc/sdc1

Hmm, strange, your rules still work here. Care to try if tracing shows
if reading the sysfs value goes wrong?
It shows here:
  readlink("/sys/.../usb5/5-2/subsystem", "../../../../../bus/usb"...,
1024) = 22
  lstat("/sys/.../usb5/5-2/serial", {st_mode=S_IFREG|0444,
st_size@96, ...}) = 0
  open("/sys/.../usb5/5-2/serial", O_RDONLY) = 3
  read(3, "000000009407\n", 512)          = 13
  close(3)                                = 0

This creates a "udev-trace" file:
  strace -s 256 -o udev-trace /sbin/udevadm test /block/sdc/sdc1
Can you send this to me?

Thanks,
Kay

I guess I've considered it a safe choice during a kernel upgrade at
some point.

I was able to unset CONFIG_SYSFS_DEPRECATED_V2 from menuconfig, which
disabled invisible CONFIG_SYSFS_DEPRECATED too. Now recent udev
versions work with my rulesets. Thanks a lot.

I'm Cc'ing the linux-hotplug to be sure anyone with such a trouble can
find the answer.

I think I fixed it for udev 133, it seems to work fine here now with the
deprecated sysfs layout. Thanks for your help!

Btw, you can remove the NAME="%k", it's the default and does not do
anthing. Instead of the kernel name matches, you can use
ENV{DEVTYPE}="partition" and ENV{DEVTYPE}="disk" to distinguish
between a disk and a partition.

And udev by default creates these links, which should be as stable as
your custom links for this device, and not depend on any probing order
or port which is used to connect:
  /dev/disk/by-id/usb-Corsair_Flash_Voyager_A500000000025423-0:0
  /dev/disk/by-id/usb-Corsair_Flash_Voyager_A500000000025423-0:0-part1

They are just a a bit longer. :)

Thanks,
Kay
