About this tag
Kernel taint is a Linux kernel mechanism that flags a running system as having loaded code or entered a state that reduces the value of any subsequent bug reports. This tag follows discussion of a proposed taint flag, TAINT_FORCED_BIND, raised by Greg Kroah-Hartman on the kernel mailing lists. The patch would mark a kernel whenever the driver-core bind or unbind sysfs files are used to manually attach or detach a device and driver, a practice fuzzers such as syzbot have used to create pairings that would not occur in normal operation. The series remains under review, so no merged release is confirmed.

It would mark a running kernel whenever someone uses the driver-core bind or unbind sysfs files to manually attach a device to a driver or detach it. He says he wants this because fuzzers such as syzbot have been...
