Linus Torvalds 3fdacf402b tracing: Fix the histogram logic from possibly crashing the kernel ... Working on the histogram code, I found that if you dereference a char pointer in a trace event that happens to point to user space, it can crash the kernel, as it does no checks of that pointer. I have code coming that will do this better, so just remove this ability to treat character pointers in trace events as stings in the histogram. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYPH9FRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qsyhAQDKiQzVJtjfsNbIWliDQOaUwJMO9tNl Qu5TUDmPbAA4fwD+MgYsnITPL+o/YcKQ+aMdj/wLLMKfIjhNkFY8wqdLvwg= =CN97 -----END PGP SIGNATURE----- Merge tag 'trace-v5.14-5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "Fix the histogram logic from possibly crashing the kernel Working on the histogram code, I found that if you dereference a char pointer in a trace event that happens to point to user space, it can crash the kernel, as it does no checks of that pointer.
