Function Documentation

int _stp_register_jprobes (  struct jprobe *  probes, int  num_probes )

Register a group of jprobes. Parameters: probes  Pointer to an array of struct jprobe. num_probes  Number of probes in the array. Returns: 0 on success. Definition at line 32 of file probes.c. References _stp_lookup_name, _stp_unregister_jprobes(), and dlog().

int _stp_register_kprobes (  struct kprobe *  probes, int  num_probes )

Register a group of kprobes. Parameters: probes  Pointer to an array of struct kprobe. num_probes  Number of probes in the array. Returns: 0 on success. Definition at line 77 of file probes.c. References _stp_lookup_name, _stp_unregister_kprobes(), and dlog().

void _stp_unregister_jprobes (  struct jprobe *  probes, int  num_probes )

Unregister a group of jprobes. Parameters: probes  Pointer to an array of struct jprobe. num_probes  Number of probes in the array. Definition at line 18 of file probes.c. References dlog(). Referenced by _stp_register_jprobes().

void _stp_unregister_kprobes (  struct kprobe *  probes, int  num_probes )

Unregister a group of kprobes. Parameters: probes  Pointer to an array of struct kprobe. num_probes  Number of probes in the array. Definition at line 63 of file probes.c. References dlog(). Referenced by _stp_register_kprobes().

Variable Documentation

unsigned long(* _stp_lookup_name)(char *name) = (void *)KALLSYMS_LOOKUP_NAME [static]

Lookup name. This simply calls the kernel function kallsyms_lookup_name(). That function is not exported, so this workaround is required. See the kernel source, kernel/kallsyms.c for more information. Definition at line 11 of file probes.c. Referenced by _stp_register_jprobes(), and _stp_register_kprobes().
