commit c2e4b24ff848bb180f9b9cd873a38327cd219ad2 upstream.
When a trace recorded on a 32-bit device is processed with a 64-bit
binary, the higher 32-bits of the address need to ignored.
The lack of this results in the output of the 64-bit pointer
value to the trace as the 32-bit address lookup fails in find_printk().
Before:
burn-1778 [003] 548.600305: bputs: 0xc0046db2s: 2cec5c058d98c
After:
burn-1778 [003] 548.600305: bputs: 0xc0046db2s: RT throttling activated
The problem occurs in PRINT_FIELD when the field is recognized as a
pointer to a string (of the type const char *)
Heterogeneous architectures cases below can arise and should be handled:
* Traces recorded using 32-bit addresses processed on a 64-bit machine
* Traces recorded using 64-bit addresses processed on a 32-bit machine

commit e523caa601f4a7c2fa1ecd040db921baf7453798 upstream.
Ours uses a u32 for the data, since we ensure it's always
aligned and it's x86 so it doesn't matter anyway.

commit 266fa2b22294909ddf6e7d2f8acfe07adf9fd978 upstream.
We have map_groups__find_by_name() to look at the list of modules that
are in place for a given machine, so use it instead of traversing the
machine dso list, which also includes DSOs for userspace.
When merging the user and kernel DSO lists a bug was introduced where
'perf probe' stopped being able to add probes to modules using its short
name:
# perf probe -m usbnet --add usbnet_start_xmit
usbnet_start_xmit is out of .text, skip it.
Error: Failed to add events.
#
With this fix it works again:
# perf probe -m usbnet --add usbnet_start_xmit
Added new event:
probe:usbnet_start_xmit (on usbnet_start_xmit in usbnet)
You can now use it in all perf tools, such as:
perf record -e probe:usbnet_start_xmit -aR sleep 1

commit caa470475d9b59eeff093ae650800d34612c4379 upstream.
The original patch introducing this header wrote the number of CPUs available
and online in one order and then swapped those values when reading, fix it.
Before:
# perf record usleep 1
# perf report --header-only | grep 'nrcpus \(online\|avail\)'
# nrcpus online : 4
# nrcpus avail : 4
# echo 0 > /sys/devices/system/cpu/cpu2/online
# perf record usleep 1
# perf report --header-only | grep 'nrcpus \(online\|avail\)'
# nrcpus online : 4
# nrcpus avail : 3
# echo 0 > /sys/devices/system/cpu/cpu1/online
# perf record usleep 1
# perf report --header-only | grep 'nrcpus \(online\|avail\)'
# nrcpus online : 4
# nrcpus avail : 2
After the fix, bringing back the CPUs online:
# perf report --header-only | grep 'nrcpus \(online\|avail\)'
# nrcpus online : 2
# nrcpus avail : 4
# echo 1 > /sys/devices/system/cpu/cpu2/online
# perf record usleep 1

commit 93df8a1ed6231727c5db94a80b1a6bd5ee67cec3 upstream.
perf currently fails to build on MIPS as there is no
tools/perf/arch/mips/Build file. Adding an empty file fixes this as
there are no MIPS-specific sources to build.
It looks like the same is needed for Alpha and PA-RISC, though I
haven't been able to test those.

commit 601083cffb7cabdcc55b8195d732f0f7028570fa upstream.
print_aggr() fails to print per-core/per-socket statistics after commit
582ec0829b3d ("perf stat: Fix per-socket output bug for uncore events")
if events have differnt cpus. Because in print_aggr(), aggr_get_id needs
index (not cpu id) to find core/pkg id. Also, evsel cpu maps should be
used to get aggregated id.
Here is an example:
Counting events cycles,uncore_imc_0/cas_count_read/. (Uncore event has
cpumask 0,18)
$ perf stat -e cycles,uncore_imc_0/cas_count_read/ -C0,18 --per-core sleep 2
Without this patch, it failes to get CPU 18 result.
Performance counter stats for 'CPU(s) 0,18':
S0-C0 1 7526851 cycles
S0-C0 1 1.05 MiB uncore_imc_0/cas_count_read/
S1-C0 0 <not counted> cycles
S1-C0 0 <not counted> MiB uncore_imc_0/cas_count_read/
With this patch, it can get both CPU0 and CPU18 result.
Performance counter stats for 'CPU(s) 0,18':
S0-C0 1 6327768 cycles
S0-C0 1 0.47 MiB uncore_imc_0/cas_count_read/

commit e8e6d37e73e6b950c891c780745460b87f4755b6 upstream.
When we introduce a new sort key, we need to update the
hists__calc_col_len() function accordingly, otherwise the width
will be limited to strlen(header).
We can't update it when obtaining a line value for a column (for
instance, in sort__srcline_cmp()), because we reset it all when doing a
resort (see hists__output_recalc_col_len()), so we need to, from what is
in the hist_entry fields, set each of the column widths.

commit b5cabbcbd157a4bf5a92dfc85134999a3b55342d upstream.
A copy of /proc/kcore containing the kernel text can be made to the
buildid cache. e.g.
perf buildid-cache -v -k /proc/kcore
To workaround objdump limitations, a copy is also made when annotating
against /proc/kcore.
The copying process stops working from libelf about v1.62 onwards (the
problem was found with v1.63).
The cause is that a call to gelf_getphdr() in kcore__add_phdr() fails
because additional validation has been added to gelf_getphdr().
The use of gelf_getphdr() is a misguided attempt to get default
initialization of the Gelf_Phdr structure. That should not be
necessary because every member of the Gelf_Phdr structure is
subsequently assigned. So just remove the call to gelf_getphdr().
Similarly, a call to gelf_getehdr() in gelf_kcore__init() can be
removed also.
Committer notes:
Note to stable@kernel.org, from Adrian in the cover letter for this
patchkit:
The "Fix copying of /proc/kcore" problem goes back to v3.13 if you think
it is important enough for stable.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
- Fix buildid processing done at the end of a 'perf record' session, a
problem that happened in workloads involving lots of small short-lived
processes. That code was not asking the perf_session layer to order
the events.
Make the code more robust to handle some of the problems with such
out-of-order events and fix 'perf record' to ask for ordered events
on systems where we have perf_event_attr.sample_id_all. (Adrian Hunter)

When processing a fork event, the tools lookup the parent thread by its
tid. In a couple of cases, it is possible for that thread to have the
wrong pid.
That can happen if the data is being processed out of order, or if the
(fork) event that would have removed the erroneous thread was lost.
Assume the latter case, print a dump message, remove the erroneous
thread, create a new one with the correct pid, and keep going.

The transaction length metrics in perf stat -T broke recently.
It would not match the metric correctly and always print K/sec.
This was caused by a incorrect update of the cycles_in_tx statistics.
Update the correct variable.
Also the check for zero division was reversed, which resulted in K/sec
being printed for no transactions. Fix this also up.

Commit 5ef7bbb09f7b ("perf tools: Allow to specify custom linker
command") was meant to enable usage non $(CROSS_COMPILE)ld linker during
perf building.
But implementation didn't take into account the fact that LD is a
pre-defined variable in GNU Make. I.e. it is always defined.
Which means there's no point to check "LD ?= ..." because it will never
succeed.
And so LD will be either that explicitly passed to make like this:
------->8-------
make LD=path_to_my_ld ...
------->8-------
or default value, which is host's "ld".
Latter leads to failure of cross-linkage because instead of cross linker
"$(CROSS_COMPILE)ld" host's "ld" is used.
Fortunately there's a way to do correct substitution of $(CROSS_COMPILE)ld
with user defined LD on command-line.
As a reference was used implementation in "tools/lib/traceevent/Makefile".
Build tested for x86_64 and ARC.
Thanks Jiri for this hint.

At some point:
commit 2c86c7ca7606
Author: Namhyung Kim <namhyung@kernel.org>
Date: Mon Mar 17 18:18:54 2014 -0300
perf report: Merge al->filtered with hist_entry->filtered
We stopped dropping samples for things filtered via the --comms, --dsos,
--symbols, etc, i.e. things marked as filtered in the symbol resolution
routines (thread__find_addr_map(), perf_event__preprocess_sample(),
etc).
But then, in:
commit 268397cb2a47
Author: Namhyung Kim <namhyung@kernel.org>
Date: Tue Apr 22 14:49:31 2014 +0900
perf top/tui: Update nr_entries properly after a filter is applied
We don't take into account entries that were filtered in
perf_event__preprocess_sample() and friends, which leads to
inconsistency in the browser seek routines, that expects the number of
hist_entry->filtered entries to match what it thinks is the number of
unfiltered, browsable entries.
So, for instance, when we do:
perf top --symbols ___non_existent_symbol___
the hist_browser__nr_entries() routine thinks there are no filters in
place, uses the hists->nr_entries but all entries are filtered, leading
to a segfault.
Tested with:
perf top --symbols malloc,free --percentage=relative
Freezing, by pressing 'f', at any time and doing the math on the
percentages ends up with 100%, ditto for:
perf top --dsos libpthread-2.20.so,libxul.so --percentage=relative
Both were segfaulting, all fixed now.
More work needed to do away with checking if filters are in place, we
should just use the nr_non_filtered_samples counter, no need to
conditionally use it or hists.nr_filter, as what the browser does is
just show unfiltered stuff. An audit of how it is being accounted is
needed, this is the minimal fix.

When setting yup the symbols library we setup several filter lists,
for dsos, comms, symbols, etc, and there is code that, if there are
filters, do certain operations, like recalculate the number of non
filtered histogram entries in the top/report TUI.
But they were considering just the "Zoom" filters, when they need to
take into account as well the above mentioned filters (perf top --comms,
--dsos, etc).
So store in symbol_conf.has_filter true if any of those filters is in
place.

Pull libnvdimm fixes from Dan Williams:
"1) Fixes for a handful of smatch reports (Thanks Dan C.!) and minor
bug fixes (patches 1-6)
2) Correctness fixes to the BLK-mode nvdimm driver (patches 7-10).
Granted these are slightly large for a -rc update. They have been
out for review in one form or another since the end of May and were
deferred from the merge window while we settled on the "PMEM API"
for the PMEM-mode nvdimm driver (ie memremap_pmem, memcpy_to_pmem,
and wmb_pmem).
Now that those apis are merged we implement them in the BLK driver
to guarantee that mmio aperture moves stay ordered with respect to
incoming read/write requests, and that writes are flushed through
those mmio-windows and platform-buffers to be persistent on media.
These pass the sub-system unit tests with the updates to
tools/testing/nvdimm, and have received a successful build-report from
the kbuild robot (468 configs).
With acks from Rafael for the touches to drivers/acpi/"

In preparation for fixing the BLK path to properly use "directed

flush its internal buffers to persistent media, similar to the x86

Instead of accessing it directly, as it uses EXPORT_SYMBOL, that has
no meaning in tools/perf and because we removed the stubs for it, i.e.
we removed the tools/include/linux/export.h file.
This fixes the build for the detached tarball sources cases and removes
one more source of entanglement with the kernel sources.

The python binding build process was still looking at the kernel
rbtree.c file, so, when doing a in-tree build it would work, but when
creating a tarball using tools/perf/MANIFEST as the contents list and
then trying to build the resulting detached sources, it failed.
Fix it by removing one level of indirection from rbtree.c in the
tools/perf/util/python-ext-sources file.

When we started adding extra stuff per array entry, growing the size of
those entries to more than sizeof(pid_t), we had to convert those sizeof
operations to the more robust sizeof(map->map[0]) idiom, that is future
proof, i.e. if/when we add more stuff to those entries, that expression
will produce the new per-entry size.
And besides that, we need to zero out those extra fields, that sometimes
may not get filled, like when we couldn't care less about the comms,
since we don't need those, but since we will try freeing it at
thread_map__delete(), we better fix it.
That is why a thread_map__realloc() was provided.
But that method wasn't used in thread_map__new_by_uid(), fix it.

We were using the include/linux/rbtree.h directly from the kernel,
which broke the build as soon as it started using rcupdate.h, to
avoid dragging the rcu header files into tools/, for which there is
no use so far, grab a copy of rbtree.h.
This is the minimal fix, later patches will copy as well lib/rbtree.c
and move rbtree.h into tools/include/, etc.

Pull ACPICA updates from Rafael Wysocki:
"Additional ACPICA material for v4.2-rc1
This will update the ACPICA code in the kernel to upstream revision
20150619 (a bug-fix release mostly including stable-candidate fixes)
and restore an earlier ACPICA commit that had to be reverted due to a
regression introduced by it (the regression is addressed by
blacklisting the only known system affected by it to date).
The only new feature added by this update is the support for
overriding objects in the ACPI namespace and a new ACPI table that can
be used for that called the Override System Definition Table (OSDT).
That should allow us to "patch" the ACPI namespace built from
incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
during system startup without the need to provide replacements for all
of those tables in the future.
Specifics:
- Fix system resume problems related to 32-bit and 64-bit versions of
the Firmware ACPI Control Structure (FACS) in the firmare (Lv
Zheng)
- Fix double initialization of the FACS (Lv Zheng)
- Add _CLS object processing code to ACPICA (Suravee Suthikulpanit)
- Add support for the (currently missing) new GIC version field in
the Multiple APIC Description Table (MADT) (Hanjun Guo)
- Add support for overriding objects in the ACPI namespace to ACPICA
and OSDT support (Lv Zheng, Bob Moore, Zhang Rui)
- Updates related to the TCPA and TPM2 ACPI tables (Bob Moore)
- Restore the commit modifying _REV to always return "2" (as required
by ACPI 6) and add a blacklisting mechanism for systems that may be
affected by that change (Rafael J Wysocki)
