Hi,

Here is a series of kprobes and x86 patches for moving
optprobe (jump optimized kprobe) onto the int3-based
instruction patching (a.k.a. text_poke_bp, introduced by
Jiri Kosina).

Since this completely moves text_poke_smp* user to new
text_poke_bp, I also remove the old text_poke_smp* code
from alternative.c. As a side effect, it also fixes a
Kconfig warning about CONFIG_STOP_MACHINE dependency
confliction.

Thank you,

---

Remove a comment about an int3 issue in NMI/MCE, since
the commit 3f3c8b8c already fixed that. Keeping this
incorrect comment can mislead developers.

Use text_poke_bp() for optimizing kprobes instead of text_poke_smp*().
Since the number of kprobes are usually not so much (<100) and
text_poke_bp() is much lighter than text_poke_smp(), this
just stops to use batch processing.

Since introducing the text_poke_bp for all text_poke_smp*
callers, text_poke_smp* are now unused. This basically
reverts 3d55cc8a, 7deb18dc and related commits.

This also fixes a Kconfig dependency issue on STOP_MACHINE
in the case of CONFIG_SMP && !CONFIG_MODULE_UNLOAD.

kprobes/x86: Remove an incorrect comment about int3 in NMI/MCE

Remove a comment about an int3 issue in NMI/MCE, since
commit:

  3f3c8b8c4b2a ("x86: Add workaround to NMI iret woes")

already fixed that. Keeping this incorrect comment can mislead developers.

kprobes/x86: Use text_poke_bp() instead of text_poke_smp*()

Use text_poke_bp() for optimizing kprobes instead of
text_poke_smp*(). Since the number of kprobes is usually not so
large (<100) and text_poke_bp() is much lighter than
text_poke_smp() [which uses stop_machine()], this just stops
using batch processing.

kprobes/x86: Remove unused text_poke_smp() and text_poke_smp_batch() functions

Since introducing the text_poke_bp() for all text_poke_smp*()
callers, text_poke_smp*() are now unused. This patch basically
reverts:

  3d55cc8a058e ("x86: Add text_poke_smp for SMP cross modifying code")
  7deb18dcf047 ("x86: Introduce text_poke_smp_batch() for batch-code modifying")

and related commits.

This patch also fixes a Kconfig dependency issue on STOP_MACHINE
in the case of CONFIG_SMP && !CONFIG_MODULE_UNLOAD.

kprobes/x86: Remove unused text_poke_smp() and text_poke_smp_batch() functions

Since introducing the text_poke_bp() for all text_poke_smp*()
callers, text_poke_smp*() are now unused. This patch basically
reverts:

  3d55cc8a058e ("x86: Add text_poke_smp for SMP cross modifying code")
  7deb18dcf047 ("x86: Introduce text_poke_smp_batch() for batch-code modifying")

and related commits.

This patch also fixes a Kconfig dependency issue on STOP_MACHINE
in the case of CONFIG_SMP && !CONFIG_MODULE_UNLOAD.

Hm, it does not build with the attached config:

arch/x86/kernel/kprobes/opt.c: In function 'setup_optimize_kprobe':
arch/x86/kernel/kprobes/opt.c:394:6: error: dereferencing pointer to incomplete type
arch/x86/kernel/kprobes/opt.c:395:6: error: dereferencing pointer to incomplete type
arch/x86/kernel/kprobes/opt.c:396:6: error: dereferencing pointer to incomplete type

Thanks,

Hmm, setup_optimized_kprobes is already removed by 2/3 (this is actually
a series of tightly coupled patches). Could you check your working tree?

32-bit appears to be the key pattern.

Ingo, please make sure your x86/jumplabel tree picked all of my patches.
This 3/3 strongly depends on the previous 1/3 and 2/3.
Without it, kprobes/opt.c can not be build because it still uses the
text_poke_params data structure which 3/3 removes.

Thank you,

Yes I know, and it was on top of -tip which already had these included:

 51b2c07b2226 x86: Make jump_label use int3-based patching
 fd4363fff3d9 x86: Introduce int3 (breakpoint)-based instruction patching

without these the third patch wouldn't even apply I think.

Thanks,

	Ingo

No, I meant below two patches:
 kprobes/x86: Remove an incorrect comment about int3 in NMI/MCE
 kprobes/x86: Use text_poke_bp() instead of text_poke_smp*()

Since the "setup_optimize_kprobe" in the error message is completely
*removed* by the second one, the above error should not happen.

Thank you,

Oh, indeed - I correctly applied them but then messed up the 
cherry-picking, that's all.

So never mind, it's all fine.

Thanks,

Hi Ingo,

x86/jumplabel branch still seems to contain only Masami's "kprobes/x86: 
Remove unused text_poke_smp() and text_poke_smp_batch() functions", with 
the the prerequisity patches missing, which effectively means it's broken 
... are you planning to fix that up, please?

Thanks,

That must be a Git server push-out delay - it should contain two patches:

 51b2c07b2226 x86: Make jump_label use int3-based patching
 fd4363fff3d9 x86: Introduce int3 (breakpoint)-based instruction patching

The kprobes patches are in perf/core, with x86/jumplabel merged in:

 ea8596bb2d8d kprobes/x86: Remove unused text_poke_smp() and text_poke_smp_batch() functions
 a7b0133ea94e kprobes/x86: Use text_poke_bp() instead of text_poke_smp*()
 c7e85c42be68 kprobes/x86: Remove an incorrect comment about int3 in NMI/MCE
 9bb15425c3bc Merge branch 'x86/jumplabel' into perf/core

Thanks,

	Ingo
