1. Concepts: Kprobes, Jprobes, Return Probes
Kprobes enables you to dynamically break into any kernel routine and
collect debugging and performance information non-disruptively. You
can trap at almost any kernel code address, specifying a handler
routine to be invoked when the breakpoint is hit.
There are currently three types of probes: kprobes, jprobes, and
kretprobes (also called return probes). A kprobe can be inserted
on virtually any instruction in the kernel. A jprobe is inserted at
the entry to a kernel function, and provides convenient access to the
function's arguments. A return probe fires when a specified function
returns.
In the typical case, Kprobes-based instrumentation is packaged as
a kernel module. The module's init function installs ("registers")
one or more probes, and the exit function unregisters them. A
registration function such as register_kprobe() specifies where
the probe is to be inserted and what handler is to be called when
the probe is hit.
The next three subsections explain how the different types of
probes work. They explain certain things that you'll need to
know in order to make the best use of Kprobes -- e.g., the
difference between a pre_handler and a post_handler, and how
to use the maxactive and nmissed fields of a kretprobe. But
if you're in a hurry to start using Kprobes, you can skip ahead
to section 2.
1.1 How Does a Kprobe Work?
When a kprobe is registered, Kprobes makes a copy of the probed
instruction and replaces the first byte(s) of the probed instruction
with a breakpoint instruction (e.g., int3 on i386 and x86_64).
When a CPU hits the breakpoint instruction, a trap occurs, the CPU's
registers are saved, and control passes to Kprobes via the
notifier_call_chain mechanism. Kprobes executes the "pre_handler"
associated with the kprobe, passing the handler the addresses of the
kprobe struct and the saved registers.
Next, Kprobes single-steps its copy of the probed instruction.
(It would be simpler to single-step the actual instruction in place,
but then Kprobes would have to temporarily remove the breakpoint
instruction. This would open a small time window when another CPU
could sail right past the probepoint.)
After the instruction is single-stepped, Kprobes executes the
"post_handler," if any, that is associated with the kprobe.
Execution then continues with the instruction following the probepoint.
1.2 How Does a Jprobe Work?
A jprobe is implemented using a kprobe that is placed on a function's
entry point. It employs a simple mirroring principle to allow
seamless access to the probed function's arguments. The jprobe
handler routine should have the same signature (arg list and return
type) as the function being probed, and must always end by calling
the Kprobes function jprobe_return().
Here's how it works. When the probe is hit, Kprobes makes a copy of
the saved registers and a generous portion of the stack (see below).
Kprobes then points the saved instruction pointer at the jprobe's
handler routine, and returns from the trap. As a result, control
passes to the handler, which is presented with the same register and
stack contents as the probed function. When it is done, the handler
calls jprobe_return(), which traps again to restore the original stack
contents and processor state and switch to the probed function.
By convention, the callee owns its arguments, so gcc may produce code
that unexpectedly modifies that portion of the stack. This is why
Kprobes saves a copy of the stack and restores it after the jprobe
handler has run. Up to MAX_STACK_SIZE bytes are copied -- e.g.,
64 bytes on i386.
Note that the probed function's args may be passed on the stack
or in registers (e.g., for x86_64 or for an i386 fastcall function).
The jprobe will work in either case, so long as the handler's
prototype matches that of the probed function.
1.3 How Does a Return Probe Work?
When you call register_kretprobe(), Kprobes establishes a kprobe at
the entry to the function. When the probed function is called and this
probe is hit, Kprobes saves a copy of the return address, and replaces
the return address with the address of a "trampoline." The trampoline
is an arbitrary piece of code -- typically just a nop instruction.
At boot time, Kprobes registers a kprobe at the trampoline.
When the probed function executes its return instruction, control
passes to the trampoline and that probe is hit. Kprobes' trampoline
handler calls the user-specified handler associated with the kretprobe,
then sets the saved instruction pointer to the saved return address,
and that's where execution resumes upon return from the trap.
While the probed function is executing, its return address is
stored in an object of type kretprobe_instance. Before calling
register_kretprobe(), the user sets the maxactive field of the
kretprobe struct to specify how many instances of the specified
function can be probed simultaneously. register_kretprobe()
pre-allocates the indicated number of kretprobe_instance objects.
For example, if the function is non-recursive and is called with a
spinlock held, maxactive = 1 should be enough. If the function is
non-recursive and can never relinquish the CPU (e.g., via a semaphore
or preemption), NR_CPUS should be enough. If maxactive <= 0, it is
set to a default value. If CONFIG_PREEMPT is enabled, the default
is max(10, 2*NR_CPUS). Otherwise, the default is NR_CPUS.
It's not a disaster if you set maxactive too low; you'll just miss
some probes. In the kretprobe struct, the nmissed field is set to
zero when the return probe is registered, and is incremented every
time the probed function is entered but there is no kretprobe_instance
object available for establishing the return probe.
2. Architectures Supported
Kprobes, jprobes, and return probes are implemented on the following
architectures:
- i386
- x86_64 (AMD-64, E64MT)
- ppc64
- ia64 (Support for probes on certain instruction types is still in progress.)
- sparc64 (Return probes not yet implemented.)
3. Configuring Kprobes
When configuring the kernel using make menuconfig/xconfig/oldconfig,
ensure that CONFIG_KPROBES is set to "y". Under "Kernel hacking",
look for "Kprobes". You may have to enable "Kernel debugging"
(CONFIG_DEBUG_KERNEL) before you can enable Kprobes.
You may also want to ensure that CONFIG_KALLSYMS and perhaps even
CONFIG_KALLSYMS_ALL are set to "y", since kallsyms_lookup_name()
is a handy, version-independent way to find a function's address.
If you need to insert a probe in the middle of a function, you may find
it useful to "Compile the kernel with debug info" (CONFIG_DEBUG_INFO),
so you can use "objdump -d -l vmlinux" to see the source-to-object
code mapping.
4. API Reference
The Kprobes API includes a "register" function and an "unregister"
function for each type of probe. Here are terse, mini-man-page
specifications for these functions and the associated probe handlers
that you'll write. See the latter half of this document for examples.
4.1 register_kprobe
#include <linux/kprobes.h>
int register_kprobe(struct kprobe *kp);
Sets a breakpoint at the address kp->addr. When the breakpoint is
hit, Kprobes calls kp->pre_handler. After the probed instruction
is single-stepped, Kprobe calls kp->post_handler. If a fault
occurs during execution of kp->pre_handler or kp->post_handler,
or during single-stepping of the probed instruction, Kprobes calls
kp->fault_handler. Any or all handlers can be NULL.
register_kprobe() returns 0 on success, or a negative errno otherwise.
User's pre-handler (kp->pre_handler):
#include <linux/kprobes.h>
#include <linux/ptrace.h>
int pre_handler(struct kprobe *p, struct pt_regs *regs);
Called with p pointing to the kprobe associated with the breakpoint,
and regs pointing to the struct containing the registers saved when
the breakpoint was hit. Return 0 here unless you're a Kprobes geek.
User's post-handler (kp->post_handler):
#include <linux/kprobes.h>
#include <linux/ptrace.h>
void post_handler(struct kprobe *p, struct pt_regs *regs,
unsigned long flags);
p and regs are as described for the pre_handler. flags always seems
to be zero.
User's fault-handler (kp->fault_handler):
#include <linux/kprobes.h>
#include <linux/ptrace.h>
int fault_handler(struct kprobe *p, struct pt_regs *regs, int trapnr);
p and regs are as described for the pre_handler. trapnr is the
architecture-specific trap number associated with the fault (e.g.,
on i386, 13 for a general protection fault or 14 for a page fault).
Returns 1 if it successfully handled the exception.
4.2 register_jprobe
#include <linux/kprobes.h>
int register_jprobe(struct jprobe *jp)
Sets a breakpoint at the address jp->kp.addr, which must be the address
of the first instruction of a function. When the breakpoint is hit,
Kprobes runs the handler whose address is jp->entry.
The handler should have the same arg list and return type as the probed
function; and just before it returns, it must call jprobe_return().
(The handler never actually returns, since jprobe_return() returns
control to Kprobes.) If the probed function is declared asmlinkage,
fastcall, or anything else that affects how args are passed, the
handler's declaration must match.
register_jprobe() returns 0 on success, or a negative errno otherwise.
4.3 register_kretprobe
#include <linux/kprobes.h>
int register_kretprobe(struct kretprobe *rp);
Establishes a return probe for the function whose address is
rp->kp.addr. When that function returns, Kprobes calls rp->handler.
You must set rp->maxactive appropriately before you call
register_kretprobe(); see "How Does a Return Probe Work?" for details.
register_kretprobe() returns 0 on success, or a negative errno
otherwise.
User's return-probe handler (rp->handler):
#include <linux/kprobes.h>
#include <linux/ptrace.h>
int kretprobe_handler(struct kretprobe_instance *ri, struct pt_regs *regs);
regs is as described for kprobe.pre_handler. ri points to the
kretprobe_instance object, of which the following fields may be
of interest:
- ret_addr: the return address
- rp: points to the corresponding kretprobe object
- task: points to the corresponding task struct
The handler's return value is currently ignored.
4.4 unregister_*probe
#include <linux/kprobes.h>
void unregister_kprobe(struct kprobe *kp);
void unregister_jprobe(struct jprobe *jp);
void unregister_kretprobe(struct kretprobe *rp);
Removes the specified probe. The unregister function can be called
at any time after the probe has been registered.
5. Kprobes Features and Limitations
As of Linux v2.6.12, Kprobes allows multiple probes at the same
address. Currently, however, there cannot be multiple jprobes on
the same function at the same time.
In general, you can install a probe anywhere in the kernel.
In particular, you can probe interrupt handlers. Known exceptions
are discussed in this section.
For obvious reasons, it's a bad idea to install a probe in
the code that implements Kprobes (mostly kernel/kprobes.c and
arch/*/kernel/kprobes.c). A patch in the v2.6.13 timeframe instructs
Kprobes to reject such requests.
If you install a probe in an inline-able function, Kprobes makes
no attempt to chase down all inline instances of the function and
install probes there. gcc may inline a function without being asked,
so keep this in mind if you're not seeing the probe hits you expect.
A probe handler can modify the environment of the probed function
-- e.g., by modifying kernel data structures, or by modifying the
contents of the pt_regs struct (which are restored to the registers
upon return from the breakpoint). So Kprobes can be used, for example,
to install a bug fix or to inject faults for testing. Kprobes, of
course, has no way to distinguish the deliberately injected faults
from the accidental ones. Don't drink and probe.
Kprobes makes no attempt to prevent probe handlers from stepping on
each other -- e.g., probing printk() and then calling printk() from a
probe handler. As of Linux v2.6.12, if a probe handler hits a probe,
that second probe's handlers won't be run in that instance.
In Linux v2.6.12 and previous versions, Kprobes' data structures are
protected by a single lock that is held during probe registration and
unregistration and while handlers are run. Thus, no two handlers
can run simultaneously. To improve scalability on SMP systems,
this restriction will probably be removed soon, in which case
multiple handlers (or multiple instances of the same handler) may
run concurrently on different CPUs. Code your handlers accordingly.
Kprobes does not use semaphores or allocate memory except during
registration and unregistration.
Probe handlers are run with preemption disabled. Depending on the
architecture, handlers may also run with interrupts disabled. In any
case, your handler should not yield the CPU (e.g., by attempting to
acquire a semaphore).
Since a return probe is implemented by replacing the return
address with the trampoline's address, stack backtraces and calls
to __builtin_return_address() will typically yield the trampoline's
address instead of the real return address for kretprobed functions.
(As far as we can tell, __builtin_return_address() is used only
for instrumentation and error reporting.)
If the number of times a function is called does not match the
number of times it returns, registering a return probe on that
function may produce undesirable results. We have the do_exit()
and do_execve() cases covered. do_fork() is not an issue. We're
unaware of other specific cases where this could be a problem.
6. Probe Overhead
On a typical CPU in use in 2005, a kprobe hit takes 0.5 to 1.0
microseconds to process. Specifically, a benchmark that hits the same
probepoint repeatedly, firing a simple handler each time, reports 1-2
million hits per second, depending on the architecture. A jprobe or
return-probe hit typically takes 50-75% longer than a kprobe hit.
When you have a return probe set on a function, adding a kprobe at
the entry to that function adds essentially no overhead.
Here are sample overhead figures (in usec) for different architectures.
k = kprobe; j = jprobe; r = return probe; kr = kprobe + return probe
on same function; jr = jprobe + return probe on same function
i386: Intel Pentium M, 1495 MHz, 2957.31 bogomips
k = 0.57 usec; j = 1.00; r = 0.92; kr = 0.99; jr = 1.40
x86_64: AMD Opteron 246, 1994 MHz, 3971.48 bogomips
k = 0.49 usec; j = 0.76; r = 0.80; kr = 0.82; jr = 1.07
ppc64: POWER5 (gr), 1656 MHz (SMT disabled, 1 virtual CPU per physical CPU)
k = 0.77 usec; j = 1.31; r = 1.26; kr = 1.45; jr = 1.99
7. TODO
a. SystemTap (http://sourceware.org/systemtap): Work in progress
to provide a simplified programming interface for probe-based
instrumentation.
b. Improved SMP scalability: Currently, work is in progress to handle
multiple kprobes in parallel.
c. Kernel return probes for sparc64.
d. Support for other architectures.
e. User-space probes.

Machine check
mce=off disable machine check
mce=bootlog Enable logging of machine checks left over from booting.
Disabled by default because some BIOS leave bogus ones.
If your BIOS doesn't do that it's a good idea to enable though
to make sure you log even machine check events that result
in a reboot.
nomce (for compatibility with i386): same as mce=off
