[PATCHv3 0/9] perf tool: Assorted fixes

[PATCHv3 0/9] perf tool: Assorted fixes

[Jiri Olsa]

hi,
sending assorted general fixes that queued
up in my other branches.

v3 changes:
  - reworked machine__create_kernel_maps to take into account
    kernel modules based on Namhyung's comments
  - fixed dso__load changes to take into account namespace switch
  - add perf test 1 fix

v2 changes:
  - rebased on current perf/core
  - detailed changelog for patch 1
  - using zfree instead of free in patch 2
  - using machine__set_mmap_name function name

Also available in here:
  https://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/fixes

thanks,
jirka

[PATCH 1/9] tools lib symbol: Skip non-address kallsyms line

[Jiri Olsa]

Adding check on failed attempt to parse the address
and skip the line parsing early in that case.

The address can be replaced with '(null)' string in
case user don't have enough permissions, like:

  $ cat /proc/kallsyms
      (null) A irq_stack_union
      (null) A __per_cpu_start
      ...

[PATCH 2/9] perf tools: Check if we read regular file in dso__load

[Jiri Olsa]

Current code in dso__load calls the is_regular_file function,
but it checks its return value only after calling symsrc__init.

That can make symsrc__init block in elf_* functions on reading
the file if the file happens to be device and not regular one.

Calling symsrc__init only for regular files. Also removing
the symsrc__destroy cleanup, which is not needed now, because
we call symsrc__init only for regular files.

[PATCH 4/9] perf tools: Move kernel mmap name into struct machine

[Jiri Olsa]

It simplifies and centralizes the code. The kernel mmap
name is set for machine type, which we know from the
beginning, so there's no reason to generate it every time
we need it.

[PATCH 6/9] perf tools: Don't search for active kernel start in __machine__create_kernel_maps

[Jiri Olsa]

We should not search for kernel start address in
__machine__create_kernel_maps function, because it's being
used in 'report' code path, where we are interested in kernel
MMAP data address instead of in current kernel address

The __machine__create_kernel_maps serves purely for creating
the machines kernel maps and setting up the kmap group. The
report code path then sets the address based on the data from
kernel MMAP event in machine__set_kernel_mmap function.

The kallsyms search address logic is used for test code, that
calls machine__create_kernel_maps to get current maps and calls
machine__get_running_kernel_start to get kernel starting address.

Using machine__set_kernel_mmap to se the kernel maps start
address and moving map_groups__fixup_end to be call when
all maps are in place.

Also making __machine__create_kernel_maps static, because there's
no external user.

[PATCH 7/9] perf tools: Remove machine__load_kallsyms function

[Jiri Olsa]

And replacing it with __machine__load_kallsyms function.

The current machine__load_kallsyms function has no caller,
so replacing it directly with __machine__load_kallsyms.
Also removing the no_kcore argument as it was always called
with true value.

[PATCH 8/9] perf tools: Do not create kernel maps in sample__resolve

[Jiri Olsa]

There's no need for kernel maps to be allocated at this
point - sample processing.

We search for kernel maps using the kernel map_groups in
machine::kmaps which is static. If vmlinux maps for any
reason still don't exist, the search correctly fails
because they are not in the map group.

[PATCH 9/9] perf tests: Use arch__compare_symbol_names to compare symbols

[Jiri Olsa]

The symbol search called by machine__find_kernel_symbol_by_name
is using internally arch__compare_symbol_names function to compare
2 symbol names, because different archs have different ways of
comparing symbols. Mostly for skipping '.' prefixes and similar.

In test 1 when we try to find matching symbols in kallsyms and
vmlinux, by address and by symbol name. When either is found
we compare the pair symbol names  by simple strcmp, which is not
good enough for reasons explained in previous paragraph.

On powerpc this can cause lockup, because even thought we found
the pair, the compared names are different and don't match
simple strcmp. Following code path is executed, that leads
to lockup:

   - we find the pair in kallsyms by sym->start
next_pair:
   - we compare the names and it fails
   - we find the pair by sym->name
   - the pair addresses match so we call goto next_pair
     because we assume the names match in this case

tools lib symbol: Skip non-address kallsyms line

Adding check on failed attempt to parse the address and skip the line
parsing early in that case.

The address can be replaced with '(null)' string in case user don't have
enough permissions, like:

  $ cat /proc/kallsyms
      (null) A irq_stack_union
      (null) A __per_cpu_start
      ...

perf symbols: Check if we read regular file in dso__load()

The current code in dso__load() calls is_regular_file(), but it checks
its return value only after calling symsrc__init().

That can make symsrc__init() block in elf_* functions on reading
the file if the file happens to be device and not regular one.

Call symsrc__init() only for regular files. Also remove the
symsrc__destroy() cleanup, which is not needed now, because we call
symsrc__init() only for regular files.

It simplifies and centralizes the code. The kernel mmap name is set for
machine type, which we know from the beginning, so there's no reason to
generate it every time we need it.

perf machine: Generalize machine__set_kernel_mmap()

So it could be called without event object, just with start and end
values. It will be used in following patch.

perf machine: Don't search for active kernel start in __machine__create_kernel_maps

We should not search for the kernel start address in
__machine__create_kernel_maps(), because it's being used in the 'report'
code path, where we are interested in kernel MMAP data address (the one
recorded via 'perf record', possibly on another machine, or an older or
newer kernel on the same machine where analysis is being performed)
instead of in current kernel address.

The __machine__create_kernel_maps() function serves purely for creating
the machines kernel maps and setting up the kmap group. The report code
path then sets the address based on the data from kernel MMAP event in
the machine__set_kernel_mmap() function.

The kallsyms search address logic is used for test code, that calls
machine__create_kernel_maps() to get current maps and calls
machine__get_running_kernel_start() to get kernel starting address.

Use machine__set_kernel_mmap() to set the kernel maps start address and
moving map_groups__fixup_end to be call when all maps are in place.

Also make __machine__create_kernel_maps static, because there's no
external user.

perf machine: Remove machine__load_kallsyms()

The current machine__load_kallsyms() function has no caller, so replace
it directly with __machine__load_kallsyms().  Also remove the no_kcore
argument as it was always called with a 'true' value.

perf tools: Do not create kernel maps in sample__resolve()

There's no need for kernel maps to be allocated at this point - sample
processing.

We search for kernel maps using the kernel map_groups in machine::kmaps
which is static. If vmlinux maps for any reason still don't exist, the
search correctly fails because they are not in the map group.

perf tests: Use arch__compare_symbol_names to compare symbols

The symbol search called by machine__find_kernel_symbol_by_name is using
internally arch__compare_symbol_names function to compare 2 symbol
names, because different archs have different ways of comparing symbols.
Mostly for skipping '.' prefixes and similar.

In test 1 when we try to find matching symbols in kallsyms and vmlinux,
by address and by symbol name. When either is found we compare the pair
symbol names  by simple strcmp, which is not good enough for reasons
explained in previous paragraph.

On powerpc this can cause lockup, because even thought we found the
pair, the compared names are different and don't match simple strcmp.
Following code path is executed, that leads to lockup:

   - we find the pair in kallsyms by sym->start
next_pair:
   - we compare the names and it fails
   - we find the pair by sym->name
   - the pair addresses match so we call goto next_pair
     because we assume the names match in this case

Hmm.. this will make map_groups__fixup_end() below not working since
it only updates if the end address of a map is zero.

And about the paranoid check, AFAIK the only case it cares is the
machine__process_kernel_mmap_event() which calls it with
event->mmap.start and event->mmap.start + event->mmap.len.  Thus, in
order for the end to be zero, both start and len should be zero.  Then
I think this condition can be changed like below:

With above change, I think it work.  But the whole point of the above
is to set the end address of vmlinux and modules.  And now we don't
need it for modules thanks to modules__parse() for passing the size.

So we only needs to update the end address of vmlinux using the start
address of the first module.  What about this then?

Thanks,
Namhyung

right, the call from machine__create_kernel_maps will have always
the start != 0 and there will be subsequent map_groups__fixup_end
call..

seems ok to me.. will you send the patch?

Subject: [PATCH] perf tools: Fix paranoid check in machine__set_kernel_mmap()

The machine__set_kernel_mmap() is to setup addresses of the kernel map
using external info.  But it has a check when the address is given
from an incorrect input which should have the start and end address of
0 (i.e. machine__process_kernel_mmap_event).

But we also use the end address of 0 for a valid input so change it to
check both start and end addresses.

Looks ok, Jiri? I noticed that Namhyung has the patch below in his git
tree, but I couldn't find it in the mailing list, Jiri, can I have your

This version has a bug that misses the call when there's no module.
I'll send a new version if Jiri agrees with the idea.

perf machine: Fix paranoid check in machine__set_kernel_mmap()

The machine__set_kernel_mmap() is to setup addresses of the kernel map
using external info.  But it has a check when the address is given from
an incorrect input which should have the start and end address of 0
(i.e. machine__process_kernel_mmap_event).

But we also use the end address of 0 for a valid input so change it to
check both start and end addresses.

[PATCH] Revert "perf machine: Fix paranoid check in machine__set_kernel_mmap()"

[Kim Phillips]

perf test 1 is failing on an arm64 box (that has a kernel module
loaded fwiw).  Running bisect resulted in commit 1d12cec6ce99 "perf
machine: Fix paranoid check in machine__set_kernel_mmap()" being the
first bad commit.  Reverting it fixes symbol resolution:

Hmm.. maybe your kernel map has non-zero start and zero end.  I
thought it was just from an old or invalid data.  But now I think that
overflow can create it..  could you please show me the mmap event?

  $ perf script --show-mmap-events

Thanks,
Namhyung

On x86, the first line in /proc/kallsyms is:

0000000000000000 A irq_stack_union

On arm64, it's:

ffff200008080000 t _head

Another arm64 box has:

ffff000008080000 t _head

(neither have RANDOMIZE_BASE set FWIW)

It would be good to know what that was, yes.

So it should have ~0ULL of the 'end' already.  I don't know why it
caused the problem..  Was it from the `perf.good`?

Hmm.. also it seems arm64 loads modules under the kernel.  Then the
fixup logic in machine__create_kernel_maps() won't work.  Also as we
don't use the map_groups__fixup_end() anymore I think it's ok just
checking the end address.

There's no difference between the output of perf.good and perf.bad (the
difference between them is this reversion patch, .good being the one
that includes it).

you mean this:

void __map_groups__fixup_end(struct map_groups *mg, enum map_type type)
...
                if (!curr->end)
                        curr->end = next->start;

?  Module symbol resolution is working, however.  Maybe because this
'paranoid' check was setting all the end addresses to ~0ULL?  Does the
design assume what maps__first() returns always has the lowest address,
and they're in sorted order?  If so, what's the fix, to re-sort
map_groups afterwards?

> don't use the map_groups__fixup_end() anymore 

?  I see map_groups__fixup_end() still being called.

> I think it's ok just
> checking the end address.

Where?  In machine__set_kernel_mmap(), like this reversion does?

The original commit says:

    The machine__set_kernel_mmap() is to setup addresses of the kernel map
    using external info.  But it has a check when the address is given from
    an incorrect input which should have the start and end address of 0
    (i.e. machine__process_kernel_mmap_event).
    
    But we also use the end address of 0 for a valid input so change it to
    check both start and end addresses.

yet the comment above the code says:

                 * Be a bit paranoid here, some perf.data file came with
                 * a zero sized synthesized MMAP event for the kernel.

I tracked the first comment insertion down to this commit:

commit 10fe12ef631a7e85022ed26304a37f033a6a95b8
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date:   Sat Feb 20 19:53:13 2010 -0200

    perf symbols: Fix up map end too on modular kernels with no modules installed
    
    In 2161db9 we stopped failing when not finding modules when
    asked too, but then the kernel maps (just one, for vmlinux)
    wasn't having its ->end field correctly set up, so symbols were
    not being found for the vmlinux map because its range was 0-0.

which, when reading that last part, one would assume start == end == 0,
therefore size also == 0, the comment only talks about a zero *sized*
event...so did the original commit 1d12cec6ce99 "perf machine: Fix
paranoid check in machine__set_kernel_mmap()" really fix that case?
Because it checks start == 0, not necessarily the size...

If not, can it be reverted until we figure out what's going on with
arm64?  It's causing a regression in the meantime...

Thanks,

Kim

Strange.. I have no idea what's the problem if the end is already
~0ULL then.

Right.  For the fixup routine to work, a map should have 0 end.

Only if the end was 0.  Modules should have non-zero end.

I think it's another problem but agree with you to fix it sorted.

Oops, sorry.  I looked a wrong branch (which I removed it but never
sent to the LKML).

Yes, the reason is all other maps (i.e. modules) are already have
non-zero end and we can fixup the end of kernel manually.

As I said I thought it only cares the start == end == 0 case and now
the problem is fixed.  So I added the start check for the fixup
routine to take care of the end address.  Otherwise kernel might have
an overlap with some module(s).

I think the right solution would be

1. sort map groups
2. set kernel end to ~0ULL in machine__create_kernel_maps()
3. fix the kernel end to the start of next module (if any) manually
   instead of calling map_groups__fixup_end()
