From 6ee64cc3020b5b5537827c71d8eaac814ad4d346 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Tue, 15 Mar 2022 23:02:00 +0900 Subject: fprobe: Add sample program for fprobe Add a sample program for the fprobe. The sample_fprobe puts a fprobe on kernel_clone() by default. This dump stack and some called address info at the function entry and exit. The sample_fprobe.ko gets 2 parameters. - symbol: you can specify the comma separated symbols or wildcard symbol pattern (in this case you can not use comma) - stackdump: a bool value to enable or disable stack dump in the fprobe handler.
