Arch Linux

Description:

The following messages appeared in my dmesg:
evdev.c(EVIOCGBIT): Suspicious buffer size 511, limiting output to 64 bytes. See http://userweb.kernel.org/~dtor/eviocgbit-bug.html

"The reason for this message is that some userspace programs specify KEY_MAX as the length argument of EVIOCGBIT ioctl. Unfortunately KEY_MAX specifies the highest keycode number whereas EVIOCGBIT expects length of the buffer in bytes. As a result the kernel returns much more data than the program expected smashing its stack and causing the program to crash. To avoid breakage a workaround was put in the kernel to return no more than 64 bytes of data when userspace issues EVIOGCBIT(EV_KEY, KEY_MAX) and to log the message that led you here." [1]
