[PATCH] INPUT: add MODALIAS to the event environment
input: add MODALIAS to the event environment
Could you please tell me sample modaliases for a number of "common"
devices (like a PS/2 mouse)?
I ask because earlier (namely, in
http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/old/gregkh-all-2.6.15.patch)
such modaliases contained commas (",") and comma is not a "trusted"
character in Udev (see replace_untrusted_chars() in udev_utils_string.c).
Thus, such modaliases were mangled and didn't work.
Only if you read it with $sysfs{modalias}, it's available in $env{MODALIAS}
and does not get mangled there, right? If you have problems with that,
let us know and we will fix it.
With the old gregkh-all-2.6.15.patch, I have:
sh-3.1# cat /sys/class/input/input1/modalias
input:b0011v0002p0004e0000-e0,1,2,k110,111,112,113,114,r0,1,8,amlsfw
sh-3.1# echo "add" >/sys/class/input/input1/uevent
sh-3.1# cat /events/1663

i.e., there is the "modalias" file in sysfs but no $MODALIAS in the
environment. Is this the problem that your patch solves (note: I haven't
tried it yet)?
